Léon Bollée, of Mans, France

CALCULATING-MACHINE.



Specification forming part of Letters Patent No. 556,720, dated March 17, 1896;
Application filed November 16, 1895. Serial No. 569,205 (No model.) Patented in France September 30, 1889, No. 201,033; in England October 22, 1889, No. 16,677, and in Belgium March 11, 1891, No. 94,099.

To all whom it may concern:
   Be it known that I, Léon Bollée, a citizen of the French Republic, residing at Mans, in the Province of Sarthe and Republic of France, have invented certain new and useful Improvements in Calculating-Machines, (for which I have obtained Letters Patent in France No. 201,033, dated September 30, 1889; in Great Britain, No. 16,677 dated October 22, 1889, and in Belgium, No. 94,099, dated March 11, 1891,) of which the following is a specification.
   This application is filed in the place of and as a continuation of my original application for Letters Patent of the United States, Serial No. 330,157, filed November 13, 1889, for the same invention, and which application was permitted to become abandoned by my attorneys without my knowledge or consent by failure to respond to the action of the office within two years, as required by the statutes.
  My invention relates to that class of devices known as "calculating-machines," and designed primarily for the operations of multiplication and division, but which can be used for addition and subtraction, as well as any mathematical calculations employing these operations.
   By the use of my device numbers with several decimal places can be multiplied or divided with much greater rapidity than by the use of logarithmic tables, and with absolute accuracy which is not attainable by the use of logarithms.
   As before stated, my invention is designed primarily for multiplication and division, and contains a series of what I call "controllers," which may be described as material embodiments of the multiplication-table - that is, mechanical means, consisting in my invention of pins of varying lengths mounted upon a plate, so arranged that when adjusted for the product of one figure by another figure two pins will, by their varying lengths, represent the units and tens of the product, which may be transmitted by rack-bars or otherwise to the units and tens wheels having indicating-figures. By employing a plurality of these plates and adjusting them individually in one direction to represent the figures of a multiplicand, and adjusting them as a unit in another direction to represent successively the figures of the multiplier, and transmitting the amounts of each partial product as soon as obtained, the product of a multiplicand of any desired length can be obtained by setting the plates as a unit and operating the transmitter as many times as there are figures in the multiplier. As compared with the mental operation of multiplying two numbers, the machine is much faster, as instead of multiplying the figures of the multiplicand one at a time by each figure of the multiplier it multiplies all the figures of the multiplicand at a time by each figure of the multiplier, and instead of setting down these partial products separately, as is done mentally, it adds them as fast as obtained to the sum of those previously obtained, so that upon multiplying by the last figure of the multiplier you have the total product instead of a series of partial products yet to be added together.
   It also embodies, as a primary and fundamental structure, a series of racks, which are moved simultaneously, and a corresponding series of gear wheels connected to numeral wheels or dials mounted in a frame and movable therewith from their normal position out of the plane of movement of said racks into the plane thereof during such portion of the movement of said racks as it may be desired to register, and out of plane thereof during the remainder of the movement, together with means for carrying over on each wheel or dial to the next higher one in succession, from the lowest to the highest denominations, any tens that may have accrued by a dial passing over a zero-indication during the portion of the movement of the racks or operation of the machine that the gear-wheels are not in the plane of movement of the racks. These racks may be straight, and in that case they would have to reciprocate, or they may be curved, in which case they might reciprocate or move forward continuously. The differential movement of the gear-wheels desired may be effected in several ways, such as by moving the racks a differential distance at each operation, or by moving them a uniform distance and previously adjusting them so that the teeth will only be engaged for the differential distance desired, or by having selecting means to throw the wheels out of or into mesh with the racks at different periods of the operation.
  My invention also relates more specifically to the use of controllers, as mentioned above, for determining the differential movements of the racks co-operating with the wheels, as above referred to. If it is desired to employ the machine for addition solely, in which each number may be considered as the product of itself by one, it will not be necessary to have controllers arranged for a multiplier of all figures, but only only for the figure 1, which simplifies the controller greatly.
   My invention also relates to various other features for simplifying and making effective the various mechanical structures necessary in calculating-machines, and such features, as well as the ones before motioned, will be more fully set forth in the following description, as well as in the claims annexed.

   E is the base-plate, from which, nearly at its ends, rise two standards F and F' fixed parallel to each other, and which support the receiver C and the two horizontal cross-bars G and G', which are properly perforated to serve as guides for the vertical rack-bars B constituting the transmitter. These standards F and F' also support a shaft H, which passes through them, and upon the left-hand end of which are fastened in order a crank-handle Ha, a gear-wheel Hb, and a cam-disk Hc, while the right-hand end carries also rigid therewith a grooved drum Hd.
   The controlling mechanism or controller A is carried by hollow rails Ia and Ib at the front and rear respectively, which are connected by cross-bars Ic and Id of an inverted-T shape at either end, and which in turn are connected at the top of the machine by a cross-bar Ie, which is vertically adjustable by means of screws and nuts. The frame formed by the bars Ia, Ib, Ic and Id is fitted in the four guides Ea, Eb, Ec and Ed placed at the four corners of the base-plate and in two other guides Fa and F'a at the top and exterior of the standards F and F'.
   At the rear of the machine is a rock-shaft If, turning in bearing Ee and Ef, rising from the base-plate, and having fast thereon at the left and right hand ends, respectively, the two levers Ig and Ih, from which are suspended by links Ii and Ij, respectively, the cross-bars Ic and Ic. The lever Ig also carries an outwardly-projecting friction-roller Ik, which runs in a cam-groove, (indicated by dotted line in Fig. 
5,) upon the inner face of the disk Hc, so that during each rotation of the shaft H by its handle Ha the hollow rails Ia and Ib will be raised parallel to each other and to the same height and then lowered to initial position. The guide Fa also carries a stub-shaft, upon which is mounted an intermediate gear-wheel which transmits motion from the gear-wheel Hb to a pinion Da of one-half its diameter, which is fast to the end of the shaft Db of the carrying mechanism journaled in the upper and rear portions of the standards F and F'.
   The principal parts of the machine are the controller A, the transmitter B, receiver C, and carrying mechanism D, to which may be added the handles J and K and connected mechanism for resetting to zero and the tape L for locating the decimal-point and reading the result.
   The controller exists of a base-plate Aa, having ten parallel slots therein serving as guides for the ten controlling-plates Ab sliding thereon, supported by projecting shoulders upon the flanged lower portions of the plates Ac and Ad at the front and rear, respectively, which, together with the connecting side pieces Ae and Af at the right and left, respectively, serve to form the framework of the controller. The side pieces Ae and Af also serve to support the horizontal plate Ag extending forward thereto from the top of the plate Ad.
   At the front of the controller are eleven plates Ah, supported upon and between the top of the plate Ac and the horizontal angle-bar Ak, which connects the front upwardly-extending portions of the side pieces Ae and Af, as seen in Figs. 2 and 3. The left-hand ten of the plates Ah are notched and numbered from 0 and 1 to 9 for the purpose of adjusting and retaining the controlling-plates Ab by their handles Ab2, the spaces between the plates Ah permitting this adjustment. The sliding piece Al, stepped for a purpose to be afterward mentioned, is adjustable by notches (see Fig. 1) in the angle-bar Ak which supports it, and serves as a decimal-pointer.
   The controller is supported by horizontal shafts Aj and Aj', journaled in the shoulders forming the lower portions of the plates Ac and Ad, and which have rollers and Aj 2 at their ends, guided in the hollow rails Ia and Ib. The double-angled plates Ai and Ai', fastened to the front of the plate Ac, take over the hollow rail Ia and serve to guide the controller in its horizontal movements.
   The controller is adjusted to the right or left, as may be desired, by means of the handle Am rotatable over a dial An, projecting forward from the plate Ac, having ten notches for determining the movement of the controller and locking the handle by means of a lug Am' upon its lower side engaging with said notches. This handle Am is pivotally mounted in the top of a vertical shaft Am2 mounted in said dial An and having at its lower end a small pinion Ao gearing in the rack Ia' projecting forward from the hollow rail Ia so that the rotation of the handle Am will move the controller A a distance (in this machine) of 3.3 millimeters for each notch of the dial An, or thirty-three millimeters for a complete rotation. The cross-bar G has a downwardly-projecting portion G' with teeth on its rear face with a pitch of 3.3 millimeters, and the co-operating rack Ap supported by an upturned flange on the forward end of the plate Ag has similar teeth. If the crank-handle Am is not exactly in a notch of the dial the teeth of Ap will abut against the teeth of G and prevent the controller from rising, and similarly, the teeth, when meshed, prevent its horizontal displacement, thus avoiding any danger of damaging the rack-rods of the transmitter B. These rods are steel, rectangular in section and sixty in number, arranged in three rows Ba Bb Bc, forming twenty groups thirty-three millimeters apart. The rods of the rows Ba and Bb have rack-teeth Ba' and Bb' on the right-hand side, while those of the row Bc have similar teeth on the left-hand side. The pitch of their teeth is 3.3 millimeters, and each rod is provided with a lug or shoulder Ba2 resting on the cross-bar G to prevent the rods descending too far.
   The controlling-plates Ab, like the groups of rods of the transmitter, are placed thirty-three millimeters apart from center to center and each has a vertical spring-pressed lever Ab2 pivoted thereto, which serves to place and retain it in the notches of its associated plate Ah. The plates Ab', which are placed on the rear portion of the plates Ab, are each provided with eighteen rows of pins arranged in nine groups of two rows in each group, the front row of each group representing units and the rear row thereof representing tens carried over from each partial product, and their positions and lengths are determined in the following manner: The lever Ab2 of one plate is placed in the notch 1 of its plate Ah and the crank-handle Am is also placed in the notch 1 of its dial An, and as the product of these numbers is one a pin equal in height to the pitch of the rack on the rod Bb, 3.3 milimeters, is placed under said rod Bb, no pin being placed under the rod Bc, as the product has no tens to be carried over. Then turn the handle to the notch 2, the product being two multiplied by one, equaling two, and place a pin of twice the length of the first beneath the rod Bb and none beneath Bc. When the whole row has been thus placed, the lever Ab2 is placed in the second notch of the plate Ah and the crank-handle is again moved successively into the notches 1, 2, 3, 4, 5, 6, 7, 8 and 9 of the dial An, and the pins are placed under the rod Bb of lengths proportional to 2, 4, 6, 8, 0, 2, 4, 6, and 8 - that is to say, the units of the products of 2 by 1, 2, 3, 4, 5, 6, 7, 8 and 9, respectively, and under the rod Bc pins of a length proportional to 0, 0, 0, 0, 1, 1, 1, 1 and 1, which represent the tens of these same products to be carried forward. Similarly for the other rows. In this manner a controlling plate or member, which is a material embodiment of the multiplication-table, is obtained, and the ten plates Ab' are identical in structure.
   The sliding piece Al is adjustable along the notched bar Ak and has a stepped piece at its back which can be fixed over any of the controlling-plates Ab. The different heights of the steps correspond, starting from the left hand, to 1, 2, 3, 4, 5, 6, 7, 8, and 9 - that is to say, when the handle Am is in notch 7 the stepped plate Al will, in rising with the whole controller A, push up the rack-rod Ba to a height corresponding to seven of its teeth, and it thus serves to set up the successive figures of the multiplier or quotient, depending upon whether multiplication or division is being performed.
   The receiver C has a framework composed of the front plate Ca having a section, as shown in Fig. 3, provided with two rows of twenty sight-apertures each, and have end pieces Cr and Cr' connected with each other by the cross-pieces Cb, Cc, and Ci. The cross-bars Cb and Cc serve to support a series of plates Cd, which, together with the front plate Ca, serve as bearings for three rows of superposed shafts Ce, Cf, and Cg, each twenty in number, and placed at a horizontal distance of thirty-three millimeters from each other. Upon each shaft Ce are placed a lug Ce', a ten-toothed pinion Ce2 loose thereon, and a fixed collar Ce3, all to the rear of its plate Cd, and between the plates Cd and Ca is a fixed arm Ce4 which extends to the right between the adjoining shafts Ce and Cf, where it is supported by a pin in one of the plates Cd, as shown in Fig 2a. Upon each of the shafts Cf, to the rear of its plate Cd, are fixed a ten-toothed pinion with two of its teeth removed and carrying a pin Cf 2 projecting rearwardly, and a ten-toothed pinion Cf 3 gearing with the pinion Ce2 immediately above it, and between the plates Cd and Ca are fixed the cam-pin Cf 4, a ten-toothed pinion Cf 5, a ten-toothed star-wheel Cf 6, a dial Cf 7, bearing the figures 0 and 1 to 9, and outside the plate Ca is fixed a milled knob Cf 8 for setting the shaft to any desired position. Upon each one of the shafts Cg, to the rear of the plate Cd, is fixed an eleven-toothed pinion Cg', from which two teeth have been removed, and having a pin Cg2 projecting rearwardly therefrom, and between the plates Cd and Ca are the eleven-toothed pinion Cg3, an eleven-toothed star-wheel Cg4, and a dial Cg5 bearing two sets of figures 0 and 1 to 9 and a blank space, arranged in reverse order, and outside the plate Ca is the milled knob Cg6, similar to Cf 8. When a dial Cf 7 passes from 9 to 0, or from 0 to 9, the cam-pin Cf 4, taking against a double beveled lug Ch' fast upon a leaf-spring Ch, which is fastened at its lower end in an extension of the cross-bar Cb and has its upper end bearing against the arm Ce4 of the shaft Ce, immediately to the left of the shaft Cf, whose cam-pin Cf 4, takes against the lug Ch, causes the leaf-spring to move the shaft Ce to the rear as a preliminary step in the carrying of the tens, which will be further explained. Upon a cross-bar (not shown) are spring-detents (not shown) for co-operating with the star-wheels Cf 6 and Cg4 for preventing accidental movements of the shafts Cf and Cg. The shaft Ce, which does not rotate, but reciprocates longitudinally, as above stated, has a bearing in the plate Ca of a sufficient depth to permit this, and a strong leaf-spring Cj fast upon the cross-bar Cc serves to hold it yieldingly in either position.
   Fb, F'b, Fc, and F'c are pins fixed in the end standards F F', upon which the receiver C is carried by corresponding holes in its end plates Cr and Cr'. The receiver C is also carries rigid therewith at its right-hand end an axis Ck, upon which, outside of the standard F', is rotably mounted a sleeve Cl, which has two arms Cg, carrying at their ends friction-rollers Cm and Cn, one or the other of which arms is by its roller engaged in the cam-grooves of the drum Hd before referred to and is there retained by a spring-lever Co rigid with said sleeve Cl and held in one or the other of the notches + or - upon a standard Cp rigid with the axis Ck. The two grooves of the drum Hd being symmetrical and inverse in direction, it follows that if by a given rotation of the drum Hd the receiver is moved to the left when the lever is in the notch + a similar rotation will move it to the right when the lever is in the notch -.
   The carrying mechanism D consists of the shaft Db, on which is fast the pinion Da, which transmits thereto in the ratio of two to one the rotary movement of the gear-wheel Hb. The shaft Db carries twenty cams Dc (of which only one is shown in Fig. 3 to prevent confusion,) so arranged that each is placed at an angular advance of four degrees thirty-one minutes from its left-hand neighbor, from which it is distant thirty-three millimeters. Each cam Dc, by means of a groove (indicated in dotted lines in Fig. 3) in its left-hand face, at each rotation moves downward a lever De, pivoted by trunnions Df in notches in the cross-bar Dg connecting the standards F and F', and which has a laterally-projecting pin De2 co-operating with the cam-groove of the cam Dc. This lever De has a pin De' at its end, projecting laterally at both sides, which on the lever being depressed by the cam passes behind the pinion Ce2 if it is in a forward position or engages therewith and rotates it one tooth if it is in a rearward position. Before the lever rises a lug Dc' upon the cam Dc strikes the lug Ce' and moves it forward, if not already in that position, after which the lever is free to rise.
   The object in having the cams arranged to act in succession instead of simultaneously is to prevent any possible failure to carry, such as would occur if the dials Cf 7 showed the amount of 999,999 and by the operation of the machine 1 was to be added to the sum already indicated. If the cams were arranged to act simultaneously, the sum shown would be 999,900 instead of 1,000,000, as it should be and will be if the cams act in succession.
   As the mechanisms J and K for resetting the upper and lower dials to zero are the same, but one of them will be described. This mechanism consists of a hand-lever K, fixed to a sleeve Ka, which is capable of sliding longitudinally and turning upon two pins Fd and F'd, fixed in the standards F and F'. The sleeve Ka is provided with arms Kb, carrying a rack Kc and a bar Kd, which is free to rise with the rack when the hand-lever K is moved backward, but is prevented from moving horizontally with said rack if the hand-lever is moved longitudinally. The bar Kd is provided with small pins Kd', so arranged that when the bar Kd is raised and the mutilated portions of the pinions Cg' are downward (the dials Cg5 being then at zero) the pins will abut against the left-hand face of the pins Cg2, which are also held at their lowest position. Thus in order to return the dials Cg5 to zero when placed in any position it is simply necessary to raise the rack and move the hand-lever K from right to left. The pinions Cg' are caused to turn so long as the teeth are in gear with the rack Kc, but are out of gear when the mutilated portion of the gear is downward. At this moment the small pins Kd' abut against the pins Cg2 and stop and retain the dials Cg5, which are now at zero. On then lowering and returning the rack the pinions are free to move.
   The traveling band L is endless and is placed above the apertures, (being possibly threaded in two parallel slots in each of the standards F and F',) but preferably mounted on two spools depending from lugs at the front and top of the standards F and F', as seen in Fig. 1, and starting from the decimal-point is divided into spaces extending over three of the dials and bearing the names of the orders of figures, as "units," "thousands," "millions," &c.
   One revolution of the crank-handle may be considered as divided into nine parts, in each of which the principal parts of the machine perform one function. If the lever Co be placed in the + notch:
   First. The receiver is moved to the right, gearing the teeth of the pinions Cf 5 in the racks Bc of the transmitter.
   Second. The controller A is raised, pushing up the rack-rods Ba, Bb, and Bc of the transmitter distances corresponding to the height of the parts contacting therewith. The rod Ba is raised by the stepped plate Al and the rods Bb (representing the units of the product of the number denoted by the position of the controlling-plates by the figure denoted by the position of the multiplying-crank Am on its dial An) are raised by the pins on the plates Ab' and none of them produce any action, not being in gear with their pinions; but the racks Bc, which alone are in gear and which represent the tens of the product to be carried over, rotate the dials Cf 7 to an extent corresponding to the number of teeth which they are raised.
   Third. The receiver is placed slightly to the right of its middle position.
   Fourth. The levers De, by their pins De', engage in succession and rotate to the extent of one tooth those of the pinions Ce2 (which are on their left hand) which have been moved back. As the pinions Ce2 are broad enough to mesh with the pinions Cf 3 directly beneath them, whichever position they may be in, this causes the dials Cf 7 to be advanced one space, and the tens are thus carried over.
   Fifth. The receiver is shifted entirely to the left, causing the pinions Cf 5 and Cg3 to gear with the racks Bb and Ba, respectively, which were raised free and held in their raised position by the controller.
   Sixth. The controller redescends and the racks are lowered by gravity, assisted by the cross-bar Ie, if necessary, so as to rotate the dials Cg5 and Cf 7 the number of divisions they have been raised. The rods Bc, being free, no longer act.
   Seventh. The receiver returns a little to the right of middle position.
   Eighth. The levers De carry over any tens which may have to be carried forward.
   Ninth. The receiver places itself exactly in the center, which was its original position.
    If the receiver-lever Co is placed in the notch the same actions will take place; but all the left-hand positions will be transferred to the right, so that those racks which were in gear in rising will be in gear descending, and vice versa, and the pinions Ce2, which were geared by the levers De on their right will be geared by the levers which are on their left. The receiving-dials thus turn in a reverse direction to the previous case, and as when turning in the first direction the numeration increases, in the other direction it diminishes. Thus, for example, to multiply 956.48 by 638, the levers Ab2 of the controlling-plates are placed in the notches of the figures corresponding, respectively, to those of the number 956.48, care being taken to place the slider Al, carrying the stepped plate, above the figure 6 of the units, after which the multiplying-crank is placed successively in the notches Nos. 6, 3, and 8 corresponding to the figures of the multiplier passing over zero between each stoppage and moving it in the direction of the arrow in Fig. 2. After each stoppage the crank-handle Ha is moved one turn. The product 610,234.24 is indicated on the upper dials at the same time that 638 appears on the lower ones. The tape L is then moved so as to bring the decimal-point to the right of the 8 of the figures 638, and the result is immediately found divided into groups of three figures, in integers and decimals, of which the names may be read off from the tape. The result in this case is 610 thousand, 234 units, and 24 hundredths.
   Addition is only a special instance of multiplication, as a number is considered as its product by one, so that if the calculating-plates are adjusted successively to certain numbers, leaving the multiplying-handle at 1, and the handle Ha be turned each time, the machine will produce the sum of these products and consequently of the numbers themselves. If the receiver-lever is in the negative notch the products, instead of being added, will be subtracted from a number previously set up on the machine and the difference will be indicated.
    Division is but multiplication reversed - that is to say, worked from the negative notch.
    As regards other operations - such as involution, evolution, &c. - they are obtained by suitably combining the four fundamental operations of arithmetic.
    It will be understood that my invention is capable of numerous modifications of the structure shown and described and all within the scope thereof, and with which it is unnecessary to cumber this specification, and that I do not desire to be limited to the exact form shown and described, but only to those structures and combinations within the terms of the following claims.

Notes:
  1. The original says De but this must be a typo.  (back)
  2. Contrary to David Weil of the Computer Museum of America, J.A.V. Turck is rather positive about this machine in his book "Origin of Modern Calculating Machines" (The Western Society of Engineers, Chicago, 1921):
    Although the Bollee machine is reputed to be a practical machine, as is attested from the models on exhibit in the Museum of Des Arts and Metiers of Paris in France, it was never manufactured and placed on the market.
    Bollee's principle has, however, been commercialized by a Swiss manufacturer in a machine made and sold under the trade-name of "The Millionaire", the U.S. patents of which were applied for and issued to Steiger.
    Hopkins constructed his multiplying mechanism on the Bollee scheme of using stepped controlling for his reciprocating racks to give the multiples of the digits, but the ingenious method of application shown in the Hopkins patent drawings illustrates well the American foresight of simplicity of manufacture.
    During the past ten years there have been a large number of patents applied for on mechanism containing the same general scheme as that of Bollee and Steiger, but up to the present writing no machines with direct multiplying mechanism have been commercialized except "The Millionaire," which is non-recording, and "Moon-Hopkins Bookkeeping Machine".
  3. A French biography of Léon Bollée is available on the web, but it focuses on his design of cars.
  4. Bollée also made complete plans for a difference engine with 27 orders of difference, by far the most extensive machine of its type ever envisaged. The machine was never built.
