To all whom it may concerm.

Be it known that I, LON BonLm, a citizen of the French4 Republic, residing at Mans, in'the Province of Sarthe and Republicl of France, have Ainvented certain new and usetul Improvements in Salculating-Machines,

(for which I have obtainedfLettei-s 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,

- March 11, 1891,)'of which the following Ypermitted to become abandon is a s ication.

This application isfiled in the place of and as a continuation of my original application for Letters Patent ot the United States, Serial No."330,157, led November 13, 1889, -for the same invention, and which ap lication was by my attorneys without my knowledge or consent by tail- 'of logarithme.A

As before stated, my invention is'designed primarilyformultiplication and division, and contains a series of what I call controllers, which may be described as material embodiments of the" mu1tip1ication-table-that is,

mechanical means, consisting in my inven-l tion of pins of varying lengths mounted upon a plate, so arranged that when adjusted for the product of one ligure by another ligure two pins will, by their varying lengths, represent th'e units and tens otthe product, which may be transmitted by rack-bars or otherwise to the units and tens wheels hat'-, ing indicating-figures. By employing a p1ural y of these plates and adjusting them indiv duallyin one direction to represent the gurcsiof-amultiplicand, and adjustingthem 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 multiplyingtwo numbers, the machine is much faster, asinstead of multiplying the iigures of the multiplicand one at a time by each gureof the multiplier it multiplies all theilgures 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 obtainedto' the sum of those previously obtained, so that upon multiplying by'the last figure of the multiplier lyou have the total product instead of a series of, partial products yetto bev added together.

t also embodies, as-a primary anu laudamental structure, a series'of racks, whichare 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 tion out ,of the plane of movementof 'sai racksinto the plane thereof during such portion of the movement of said racks as it may be desired toregister, and outof the plane thereof during the remainder of the movement, together with means for carrying over on each wheel or dial to thenexthigher one in succession, 4f rom the lowest to the highest denominations, any tens that may have accrued by a dial passing over a zero-indication during the porton'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. 'ihe difforen tial movement of the ear-wheels desired may be effected' in severa 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 thc differential distance desired, or by having selecting means to throw the wheels out of or inte mesh with the racks at different periods of the operation.

My invention also relates more specifically tothe use'of controllers, as mentioned above, for determining the differential movements of the racks cooperating -wit-h the wheels, as above referred to. If it is desired to empio the machine for addition solely, in which eac 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 for the ligure 1 which simpliiies the controller greatly.

My invention also relates to various other features for simplifyln and making eiiective the various mechanica 'structures necessary in calculating-machines, and such features, as

'well as the ones before metioned, will be more full set forth in the following description, as w as in the claims annexed.

I have illustrated my invention in the accompanying six sheets of drawings, in which the saine reference-letters are used to designate identical parts. in all the figures, of which- Figure 1 is a perspective view of the front of the machine.` Figs. 2 and 2 together constitute a plan, partly in section, taken on different planes. Fig. 3 is atransverse vertical section taken through the axis of the handle of the controlling apparatus, and- Figs. 4 and li :re views of the opposite ends of the mach ne.

E is thebase-plate,.from which, nearly at its ends, rise two standards F and F' dxed parallel to 'each other, and whichsnpport the receiver C and the two horizontal crossbars G and G', which are properl perforated to serve as guides for the vertica rack-bars B constitutin the transmitter. These standards F and also support a-shaft H, which through them, and upon the leftfhand end of which are fastened in order a crank-handle Ila,'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 controllerA iscarried by hollow rails Ia and Ib at the front and rear respectively, which areconnected by cross-bars Ic and Id of an inverted-T shape at either end, and which in tum are connected at the top of the machine by s crossbar le, 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 guidesEa, Eb, Ec and Ed placed at the four corners of the base-plate and in two other guides Fa and F'a att-he tcp and exterior of the standards F and F' At the rear of the machine is a rock-shaft l turnin in bearings Ee and Ef, rising from c base-p te, 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 U, respectively, the cross-bars .extending portions of the side Ic and Id. The levenig also carries an o twardlylprojecting friction-roller Ik, which runs in scam-groove, (indicated by dotted line in Figli, upon theinner face of the diskHc, so that du each rotation of the shaft H by its handle a the hollow ,rails Ia and Ib will be raised parallel to each other and to the same height and then lowered to initial tion. The guide Fa also carries'a stub-amt, upon which is mounted an intermediate gearwheel which transmits mot-ion from the gearwheel Hb to s inion Da of one-half its diameter, which s fast to the end 4of the shaft Db of the carrying mechanism urnaled in the uuger and rear portions of t estandards F an The rincipal parts of themachine are the control er A, the transmitter B, receiver C, and carrying mechanismjD, te whichl 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 consists of a baseplate Aa, having ten rallel slots therein serving as guides for t e ten controlling-plates Ab sliding thereon, su ported by projecting shoulders upon the anged lower portions of. the plates Ac and Ad at the front and rear, repectively, which, together with the connecting side pieces Ae and Af at the right and left, respectivel Y, serve to form the framework of the controler. The side pieces Ae and Af also serve to support'the horizontal plate Ag extending forward thereto from th'e top cf 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 an 1ebar Ak, which connects the front upwa ly- ;ieces Ae and Af, as seen in Figs.- 9 and he leftfhand ten of the plates Ah are notched and numberedfromOandl to 9 for the nurposeof adjusting and retainin the controlling-plates Ab by their handles A the between the plates Ah permitting this adjustment. The sliding piece "Al, stepped for s purpose to be afterward mention ,is adjustable b notches (see Fig. l) in the angleber which supports it, and serves as a decimalpointer.

The controller4 is supported b shafts AJ' and AJ', journaled in formin the lower portions of the lates Ac and A and which have rollers at their ends, guided in thc hollow rails a and Ib. The do able-angled plates Ai and A1', fastened to the front of the plate Ac,.talrc over the hollow rail Ia and serve to guide the ccntroller 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 e shoulders horizontal llO IOO

, said notches.4

lug Am' upon its lower side engaging with This handle Am is pivotally mounted in the top of a vertical shaft Am2 mounted in said dial An and having atits lower end a small pinion Ao gearing in the rack Ia. projecting forward fromthe 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 A'n, orthirtythree millimeters for a complete rotation. The' cross-bar G hasa downwardly-projecting portion G' with teeth on its -rear face with a pitch of 3.3- millimeters, and the co-operating rack Apsupported" by an upturned flange on the forward end of the' plate Ag has similar teeth. If the crankhandle Am is not exactly in a notch of the dial the teeth of Ap will abut against the4 teeth of- Gv 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 steely rectangular in section and sixty in number, arranged in three rows BafBb-Bc, forming twenty groups thirty-three millimeters apart. The rods of the rowsBa and Bb have rackteeth Ba.' and Bbl 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 Ba resting on the cross-bar G to prevent the rods descending too far.

The controlling-plates Ab,1ike the groups of rods of the transmitter, are placed thirtythree millimeters apart 'from center to center and each has -a verticabspring-pressed lever Ab 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 ot two rows in each group, the front row of each group representing units and the rear row thereof representf ing tens carried over from each partial product, and their positions and lengths are de`` termined in the following manner: The lever Abof one plate is'placed in thenotch '1 of its plate Ah and the crank-handle Amis also Aplaced 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 racko'nthe rod B'b, 3.3 millimeters, 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 rst beneath the rod Bb and n`one beneath Bc. 'h'en the whole row has' been thus placed, the `lever Ab is placed in-the second notch of the plate Ah and the crank-handle is again A moved successively into the notches 1,2, 3,4, 5, 6, 7, 8 and 9 of the dial An, and the pins areA placed under the rod Bb of lengths proportional to 2, 4, 0, 8,0, 2,4, 6 and .S-that is to say, the units of the products of 2 by 1,2, 3, 4, 5, 6, 7, 8 and 9, respectively, and lunder the rod Bc pins of a length proportional te 0 0, O, 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 multipli'cation-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 diterent heights of the steps correspond, starting from the left hand, to 1, 2, 3, 4, 5, 6, 7, 8, and 9-that iste 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 orquotient, dependingxppon whether multiplication or division is ing performed.

The receiver C has ag framework composed of the front plate Ca having a section, as shown in Fig. 3, provided with two rows of twenty sight.apertureseach, andl have end pieces Cr 95 and Cr' connected with eachother by the crosspieces Cb, Cc, and Ci. The cross-bars Cb and Cc serve to supporta series of plates Cd,which, together with the front plate Ca, serve as bearings for three rows of su shafts Ce., Cf, and Cg, each twenty in number, and placed at a horizontal distance of thrtythree millimeters from each other. Upon each shaft Ce are placed a lug Ce', a ten-toothed inion Ce2 loos'e thereon, -and a fixed collar all to the rear of. its plate Cd, and between the plates Cd and Ca is a xed arm Cetwhich extends to the right between the adjoining shafts Ce and Cf,- where it is supported by a pinin one of the plates Cd, as shown in Fig. 2.. Upon eachof the shafts Cf, to the rear of its plate Cdare fixed a ten-toothed pinion with two of its teeth removed and carrying a phi Cf projecting rearwardly, and a ten-toothed pinion Cf gearing with the pinion Ce immediately above it, and between the plates Cd and Ca are fixed the cam-pin Off, a ten-toothed pinion Cf, a ten-toothed star-wheel Qf, a dial Cf?, bearing the iigures 0 and 1 to 9, and outside the plate Ca is fixed a milled knob Cf* for setting the shaft to any desired position. Upon each one o the shafts Cg, to the rear of the plate Cd, is fixed au eleven-toothed pinion Cg', from which two teeth have been removed, and having a pin Cg projecting rearwardly therefrom, and between the plates Cd and Ca are the eleven-toothed pinion Og, an eleventoothed star-wheel Cg, and a dial Cg 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 Cg, similar to Cf. Vhen a dial Cf' passes from 9 to 0, or from 0 to 9, the camin Cf, taking inst a double beveled lug C fast upon a lea `spring IOC IIO

Upon a cross-har (not shown) are sprin -detents (not shown) for co-operating with t e star-wheels Cf and Cg for preventing accidental movements ot the shafts Cf and Cg. The shaft Ce, which does not rotate, but' reclprocates longitudinally, as above stated, has a bearing in die plm ca of a aufncient depth to permitthis, and a strong leafspring ("4' tast u n the cross-'bar Ccserves to hold it yielding y in either position.

which transmitsthereto in the ratio of two to one the rotary movement o! the gear-wheel Hb. The shaft Db 'carries twenty cams De, (of which only one iss'hown in Fig. 8 to 1prevent confusiom) so arranged that eac is placed at an vance of tour degrees thirtyone minutes from its lett-handneighbor, 'from which it is distant thirty-three millimeters. Each cam Dc, means of a groove (indicated in dotted lines hand face, at eachrotation moves downward alever De, pivoted bytrunnions Df in notches in the crossbar Dg connecting the standards F and F', and which has a laterally-projecting pin De 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 Ce ii it is in a forward position or engages therewith and rotates it one tooth it it is in a rearward position. Before the leverrises a lu Dc upon the cam Dc strikes the lug Ce' an moves it forward, if not alread inthat position, ai'- tar which the llever in ree to rise.

The obiect in having the cams arranged to a) ,in its left act in succession instead of simultaneously is to prevent any possible failure to carry, such as would occur the dials Cf 7 showed the amount of 999,99 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 999,000 instead of 1,000,000, as it should be and will be if the cams act lnsuccession.

As the mechanisms J and K for resetting the `up r and' lower dials to zero are the same, ut one of them will be described. This mechanism consists of s hand-lever K, ilxed to a sleeve Ka, which is capable o! slidin; longltudinall and turnin 'upon two pins F and F'd, ilx in the stan ards F and F'. The sleeve Ka is provided with arms Kb, carrying a rack Kc and a bar Kd, which ls free to rise with the rack when the hand-lever K is moved backward, but isrprevented from moving horizontally with said rack if the hand-lever is moved lon gitudinally. The bar Kd is provided with small ins Kd', so ar-, ranged that when the bar d is raised and the mutilated portions in the pinions C'g' are downward (the dials Cg being then at xero) the pins will abut against the left-hand face of the pins Cg, which are also held at their lowest ition. Thus in orderto return'the dials it is simplginry to raise the rack and move the d-lever K from right to leit` The `pinions-Cg' are caused to turn so longI as the-teeth are in rwith therackKc, but are out of gear w `en the mutilated portion of thevgear is downward. At this moment the small-pins Kd'but against the pins Cg' and stop and retain the dials Cg, which are now at zero. Onthen lowering and returhingthe rack the pinions are to move. "v

The traveling band L is sndle and is placed above the a res, be possibly threaded in two l slots in eac ot the standards F and but preferblymounted on two spools depending from lu atlthe front and top ot-the standards F an F', asseen in Fig. l, and starting from the decimalint is d vided into spaces extendingover ree ofthe dials and bearing the names ot the orders of ilgures, as unita thousandsf millions, 5o. A

One revolution of the cranbhandle may be considered as divided into nine parts, in each oi which the princi l parts ot the machine perform one inn on. If the lever Co be placed in the notch:

First. The receiver is moved to the right, gearing the teeth ci the pinions Cf' in the racks c of the transmitter.

Second. The controller A is raised, pushing np the rack-rods Ba, Bb, and Bc`ot the transmitter distances corresponding to the height of the parts contacting therewith. The rod Ba is raised l rods Bb (representing the units of the product of the number denoted by the position of the to zero when placed in any position by the stepped plate A1 and thevhe - sition by the controller.

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 Al," 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 ot be carried over, rotate the dials Cf to an extent corresponding to the number of teeth which they are raised.

Third. The receiver lis 'placed sli gh'tly to the' right of its middle position. Fourth; The levers De, b'y their pins De', 'engage in succession and rotate to the extent of one tooth thosoof the pinions Ce (which are on their left hand) which have bee'nmoved hack. As the pinions Ce2 are broad venough to mesh with the pi'nions Cf directly beneath them, whichever position they may be in, this causes the dials Cf to be advanced one space, and the tens are thus carried over.

Fifth. The receiver is shifted entirely to the left, causing the pinons Cf?4 and Gg tolg'ear with the racks Bb andBa., iespecti vel y, which were raised free and held in their raised-po- Sixth. The controller -rcdescends and the' racks are lowered by gravity,'assisted by the cross-bar Ie,-if necessary, so as to rotate the they have been .;raised. T-he rods Bc, beingk free, no louger'aet. l

Seventh. 'Ilie receiver returns a little to the right of itsmiddle 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 wasits original posit-ion. If the receiver-lever 'Co is'placed in the notch the same actions will take place; but' all the left-hand positions Awill be transferred to the right, so that those raclis'uhich were in gear in rising will be in gear descending,

and vice' versa, and the pinions CP2, \\lich= were geared by the levers De on their right will be geared bythe levers which are on theirleft. The receiving-dials thus turn ina reverse di- Yeetion 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 Ab of the controlling-plates are placed in the notches of the tigurescorre spending,l respectively, to those of the number 956.48, care being-taken to place the slider AI, carrying the stepped plate, 'above the tgure 6 of the nits, after which the multiplying-crank is placed successively in. tho

-notches Nos. (i, 3, and' 8 corresponding to the figures 'of the multiplier passingover zero between each stoppage and moving it in the direction of the arrow in' Fig. 2. After each stoppagethe crank-handle ia is .moved one turn. 'l`he product '6 l0,ff34l24isindicated on; 'the upper dials at the sametime'thatGBS appears on' the 'lower buss. The tape L1 is then moved so aste hring the'dccimal-point to the right of the 8 of' the figures 638, and the result is immediately found divided into groups of three gurcs, in integers and decimals, of which the names may be read ot from the tape. The result in this case is 6 10 thousand, 234 units, and 24 hundredths. A

' Addition is only; a special instance of multiplication, as a number is considered as its product byone, so that if th'c calculatingplates are adjusted successively. to certain numbers, leavin the multiplying-handle at 1, and the handle abe turned each time, the machine will produce the sum of these products and consequently of the numbers themnotch the products, instead of being added, will be'subtraoted from a number previously set up on the machine and the difference will be indicated.

' Division is but multiplication reversedthats to say, worked from the negativo notch.

As' regards other operations-such as involution, evolution, incr-thtay` are obtained by suitably combining the fourfundamental operations jot arithmetic. V e It will be understood hatln'y invention iscapable of numerous modicat-ions of the structure shown and described 'and all within the scope thereof, and with which it is unnecessaryto .cumber this specification, andthat I do not desire to be limited to the .exact/form shown and described, butonly to those structures and' combinations within the terms of the following claims.'
