CALCULATING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 767,468,dated August 16, 1904.

I Application filed November 2, 1903. Serial No. 179,625. (No model.)

To all whom, it may concern.-

Be it known that I, WVILLIAM F. YAXLEY, residing at Chicago, Cook county, Illinois, have invented certain new and useful Improvements in Calculating-Machines, of which the following is a specification.

My invention relates to calculating-machines having a series of key-controlled wheels or dials by which amounts corresponding to the value of the key or keys operated are registered and totalized; and the object of my invention is to provide a simple and inexpensive machine of this character embodying new constructions and principles of operation, as will be apparent from the description hereinafter given.

In the drawings, Figure l is a plan view of my machine; Fig. 2, an end elevation thereof; Fig. 3, a plan view of the machine with the top of the casing broken away; Fig. 4:, a section on line 4: of Fig. 3; Fig. 5, a detail view of the carry-one mechanism; Fig. 6, a section on line 6 of Fig. 1; Fig. 7, a diagrammatic view showing another differential in distance between the lugs on the operating rod on bar and between the operating levers, respectively; and Fig. 8, a detail view of the modified form of construction of the operating rod or bar.

. The operating parts of my machine, with the exception of the key-buttons, are inclosed in the present instance in a suitable casing comprising a base 10, end walls 11, front wall 12, rear wall 13, and top 14. Upon the base are supported standards 15, to which is secured a main shaft 16, extending transversely of the machine and constituting the axis for aseries of adding-wheels 17, which are loosely mounted on such shaft. These wheels, which indicate units, tens, hundreds, thousands, and so on, are each provided on their right-hand side or face with a ratchet-wheel 18, whereby such wheels 17 are actuated in the manner hereinafter described. These adding-wheels may be of any number according to the desired capacity of the machine, and in the present instance I have shown a series of eight of these wheels, so that the machine is capable of registering up to one hundred millions. Sight-openings 1 1 are provided in the top of the casing to expose the indications on the adding-wheels. Each of the add1ng-wheels is provided on its periphery with four series of figures, from 0 to 9, although any number of such series may be employed; but the number shown is considered preferable for the reason that the extent of movement of the parts for actuating the wheels is lessened. he ratchet-wheels 18 are provided with marginal teeth corresponding in number with the figures on the adding-wheels.

The mechanism for actuating the addingwheels comprises a series of lever-arms 19, corresponding in number to said wheels and pivoted loosely upon the main shaft. These lever-arms have hub portions formed into segmental gear-wheels 20 and are provided at their outer ends with pivoted spring-pressed pawls 21, adapted to engage the ratchetwheels 18, and thereby actuate and rotate the adding-wheels a distance corresponding to the amount of movement or throw of the lever-arms.

A second shaft 22 is mounted between the standards 15 and arranged in front of the adding wheels. Similar operating levers 23, equal in number to the adding-wheels, are pivoted intermediate of their length to this shaft and terminate at their rearward ends in geared segments 2&, adapted to engage the scribed, whereby the movement of any one of the operating-levers 23 is communicated to its adding-wheel. The forward ends of these levers are drawn upward by means of suitable springs, as the springs 25, with the result that the actuating-levers 19 are normally held against stops 26, arranged on the top of the casing, as shown in Fig. 4:.

A vertically-swinging bailcomprising arms 27 and cross-bar 28 is pivoted to the shaft 22 near its ends and yieldingly held in a normal horizontal position by means of a spring 29,

as shown in Fig. 1. The parallel arms 27 of the bail are provided with slots through which passes a bar 30, capable of sliding but prevented from rotating with respect to the bail by reason of the angular construction of the bar and slots. This sliding bar is provided on its rear edge with aseries of projecting segmental gear-wheels 20, hereinbefore debail is depressed.

lugs 31, one for each lever-arm 19, and so arranged with respect to these lever-arms that only one of the lugs will engage a lever at a time when the bail swings downwardly, while the other lugs will be permitted to pass by. To accomplish this result, the distance between the lugs is diiferential with respect to the distance between the levers, and in the present instance this differential is expressed by the ratio 7 to 8; but any other ratio may be adopted so long as the stated purpose is effected. Referring to Fig. 3, the sliding bar is in such position that its first lug on the right will contact and actuate the lever of the units-wheel when said bail is depressed, while all the other lugs will clear their respective levers. WVhen the bail and also the sliding bar carried thereby are swung downwardly while the parts are in the relative position indicated in Fig. 3,'

the first lug on the right-that is, the unitslugwill contact, and consequently actuate the lever-arm of the units-wheel a certain distance, according to the value of the key depressed, as hereinafter explained. hen the bar is moved one unit of space to the left in a manner to be described, the second lug from the right-hand endthat is, the tens-lugwill be brought into operative relation with the tens-leverthat is, the lever of the tenswheelwhile all the other lugs, including the units-lug, theretofore in operative relation with the units-lever,will be in a position to pass by or clear their respective levers whenever the Consequently at this time the tens-wheel alone will be actuated. Further shifting of the sliding bar to the left a space at a time with respect to the bail which supports it will bring the other lugs into operative relation with their respective levers, so that any one of the operating-levers is capable of being actuated by the sliding bar, whose position is controlled by the operator. The extreme movement of such bar to the left will bring the last'lug on the left into operative relation with the lever of the last wheel on the left. According to the construction shown when the bar has been shifted to this extreme position just described the units-lug is brought into the same vertical plane as the tens-lever, and to avoid contact and actuation of such tens-lever under these circumstances the tenslug is made longer than the others and its tens-lever is made correspondingly shorter, with the result that such units-lug will clear the end of this shortened tens-lever when in the same vertical plane as the latter, and the last lug on the left will then be the only one to contact a lever-arm when the bail is depressed. In this manner the eight lugs are capable of operating the eight levers; but the operation is permitted of only one lug at a time.

In order to give the sliding bar a step-bystep movement and enable it to be shifted a proper distance or space, I provide the same into operative relation with its lever.

with an escapement comprising a pawl 32, which cooperates with a series of ratchet-teeth 33 on the under side of the sliding bar, whereby the bar is held in set or adjusted positions against the tension of a spring 34, tending to draw the bar to the left. This pawl, which. is pivoted at 35 to the cross-bar of the bail, is provided at its opposite ends with teeth 36 37, adapted to alternately engage the ratchetteeth. The distance between these ratchetteeth bears such a relation to the distance between the lugs of the bar that the escapement will permit the said spring 34 to shift the bar sufficiently to draw one lug from operative relation with its lever and bring the nextilig 1e pawl of the escapement is spring-pressed as to its right-hand end, Fig. 6, in suitable manner, as by a coiled spring 38, which tends to hold the teeth 37 in engagement with the ratchet-teeth 33. The right-hand end of the pawl is provided with a pin 39, extending to the front of the machine, as shown in Figs. 3 and 4, in the range of operating mechanism now to be described.

A shifting rod 40 is arranged to slide transversely of the machine in bearings 41, formed in standards 42, secured to the base of the casing. This rod is capable of sliding longitudinally, but prevented from rotating. An operating-handle or sliding key 42, projecting through a horizontal slot in the front wall of the casing, is secured to the rod, whereby such rod may be shifted laterally to the right against the force of a spring 43, tending to thrust the rod to the left. The rod 40 is provided on its inner or rearward side with a short pin 44, located at such a point intermediate of the length of the rod that when the operating parts are in their normal position such pin will contact and engage the pin 39, extending from the pawl of the escapement, as hereinbefore described, with the result that the pawl is prevented during such contact from acting freely by reason of the depression of its righthand end against the tension of the spring 38. A movement of this red to the right by the operator removes the short pin 44 from such contact with the pawl-pin 39 and enables such pawl to work freely for the purposes hereinafter made apparent. The rod is restored to normal position by its spring 43. The lefthand end of the rod 40 is provided with an arm 45, extending inwardlythat is, toward the rear of the machine-and in the same horizontal plane as the sliding bar in order to move such bar to the right when the rod 40 is moved in the same direction, as described. Before contacting the bar the arm 45 has a slight movement sufficient to disengage the pins 39 and 44 and permit the pawl to act freely when the bar is moved to the right, at which time the pawl will trip over the ratchetteeth.

In the left-hand corner of the machine-casing next to the operator is a wedge 46, which is arranged to slide in suitable grooves and connected to a push key or lever 47, passing through the top of the casing. This wedge is adapted to be moved or shifted by thispush-key against the left-hand end of the sliding rod 41, with the result that such rod will be slightly moved to the right, but sufficiently to cause disengagement of the two pins 39 and 44 for a purpose hereinafter made apparent when the operation of the machine is described.

Ten operating keys 48 are provided, the same being numbered 0 to 9, both inclusive, which numbers represent the value of the respective keys. These keys have vertical stems or rods 49, which bear in and are guided by a series of openings in two horizontal cross bars 50 in the standards 42. These keys are normally upwardly springpressed by the coiled springs 51. Suitable means are employed for giving each key an amount of depression corresponding to its value. For instance, the N o. 1 key has a certain or unit amount of depression, while key No. 2 has twice that amount of depression, and so on. plish this result by providing a series of stepby-step stops 52, arranged on the base of the machine and immediately below the lower ends of the key-rods, whose downward movement is thereby limited. The highest step is immediately below the cipher-key and the lowest step below the N o. 9 key. Each keyrod or step has a pin 53 extending toward the rear of the machine and normally above or in contact with the upper edge of the crossbar of the swinging bail, with the result that a depression of any one of the operating-keys will swing the bail downward a distance corresponding to the value of the key 50 oper ated.

The carrying device comprises in the present instance a series of levers 54 and pawls 55, operatively connecting the indicating-wheels for the purpose of carrying one from one wheel to the next. These levers 54 are arranged below and at one side oftheir respective wheels, (with the exception of the last wheel on the left, which obviously needs no carrying-lever,) the same being pivoted intermediate their length on short standards 56 to permit the levers to swing in a vertical plane. The rear end of each lever is turned upward to form a wedge or triangular-shaped tooth 57, which is adapted to be contacted and moved by any one of a series of pins 58. All the wheels with the exception of the last one on the left are provided with one of these pins for each series of figures thereon, and as such wheels in the present instance have four series they are each provided with four pins 58, spaced equidistantly on the left-hand face thereof near the periphery and in position to contact and actuate the levers. An arm 54 In the present instance I aceom projects laterally to the left from the forward end of each lever 54, and upon the free end of such arm is pivoted the long vertically-extending pawl 55, which engages the ratchetteeth of the indicating-wheel next to the left of the one with which its lever 54 directly cooperates. Depression of the rear end of any one ofthe levers 54 by one of the pins 58 will depress such end of the lever and rock the other end and the pawl upward, with the result that the wheel with which the pawl cooperates is advanced one space or number. Besides acting to operate the wheels, as described, these pawls also serve as detentpawls to keep the wheels from overthrowing. The amount of rocking of these levers may be adjusted to a nicety by a series of adjusting-screws 59, screwing into short posts 60.

In practice the adding wheels are first brought to Zero position and the sliding key 42, together with its rod 41, moved to the right, with the result that the sliding bar is also shifted to its right-hand position, the escapement permitting such shifting at this time owing to the fact that the pins 39 and 44 are now disengaged. hen the sliding key is released, such key and rod are restored to normal position by the spring 43 and the pins 39 and 44 are again in engagement. The machine is now set ready for the calculating operation. To clearly describe the operation, we will take, as an example, the addition of the two numbers 786 and 402. The first number is indicated on the machine by depressing the 6 key, which will swing the bail as well as the sliding bar downward six spaces. As the first lug on the right that is, the units-lugis now in operative relation with the units-lever, the units-wheel will be moved such a distance as to expose a 6 through the sightopening. During this downward movement of the bar all the other lugs pass freely on one side of their respective operating-levers. After the key 6 is released the bail, bar, and units-lever are all restored to normal position by their respective springs. Then the bail returns to normal position, as described, the pin 39 of the escapement is brought into contact with the pin 44 on the bar 40, with the result that the pawl will permit a movement of the sliding bar a distance of one tooth, which is one-half the distance required to bring the next or tens lug in operative relation with its operatinglever. The 8 key is next depressed, whereupon the first movement will cause disengagement of the pins 39 and 44 and allow the pawl to trip the ratchet another tooth, thereby permitting the sliding bar to move to the left another space and bring the tens-lug in position to operate the tens-lever. Further movement causes the tens-lug to thus actuate the tens-lever and indicate 8 on the tens-wheel. The actuating parts are restored as before and the sliding bar shifted a single space to the left. hundreds-lug on the sliding bar is caused to actuate the hundreds lever and wheel, with the result that the number 7 86 is now inindicated on the machine. It being desired to add 402 to 786, as hereinbefore suggested, the machine is reset by operating the sliding key 42 in the manner already explained. The 2 key is now depressed, and the unitswheel is turned so as to expose the figure 8 through the sight-opening. As the next figure in the number to be added is a cipher, the depression of the 0 key will simply move the swinging bail sufficiently to operate the escapement and shift the sliding bar a single space, as already made apparent, but without affecting the tenswheel. The 4 key is now depressed, whereupon the sliding bar is first moved another space, so as to bring the hundreds-lug into operative relation with its lever and transfer the value of the key so depressed to the hundredswheel. As the addition of 4 upon the hundredswheel will move such wheel beyond its 9, the carry-one mechanism is brought into operation, for after the figure 9 has passed the sight-opening one of the pins 58 of the hundreds-wheel will contact the tooth 5'7 of the lever 54 belonging to that wheel, and thereby cause its long pawl 55 to move upward a distance of onetooth and advance the thousands-wheel one figure, so that the thousands-wheel will now expose 1 through the sight-opening. The hundreds-wheel after having passed the 9, as stated, continues until the figure 1 of the next series or set of figures appears through its sight-opening, whereupon the machine indicates 1188 as the result of the addition. The addition of other numbers is performed in the same manner, the total always appearing plainly through the sight-openings. The wheels are set to Zero position by pushing the sliding key 42 to its limit of stroke to the right and then commencing with the units-wheel by adding sufiicient thereto in the manner above described to make ten, whereupon 0 will appear through the sight-opening. This operation should be repeated until all the wheels show 0.

For the purpose of adding a column of one denomination of figures or'the repeated addition of the same figure in one denomination, as ,in multiplication, the key or lever 47 is pulled outwardly, thereby causing the wedge 46 to shift the rod 40 and release the pawl of the escapement, with the result that the same lug can repeatedly actuate the same lever and wheel. Any one of the wheels can be thus operated repeatedly by bringing its lug in cooperative relation with its lever by depression of the O key the required number of times.

By the use of my machine a column of figures may be totalized by a series of simple and rapid operations. Moreover, my ma- The 7 key is now depressed, and the chine is comparatively simple in its construction and operation considering its capacity.

he differential in distance between the lugs and the operating-levers may be varied so long as the intended operation follows, and in order to show a variation in such difierential I have illustrated the bar and ends of the operating-levers in a diagrammatic way, the

lugs being spaced or separated by distances corresponding to the numbers or

ratios

7, 6, 5, 4, 5, 6, and 7 and the levers by the numbers or

ratios

8, 7, 6, 5, 6, 7, and 8. Again, the bar or rod for actuating the operating-levers may partake of a different construction, and instead of moving or sliding laterally in order to present the proper lug the bar or rod may be made to rock or rotate with the same results. In Fig. 8 I have shown such modification, in which the rod or bar 61 is provided with a series of lugs 62, properly arranged and spaced in spiral fashion on the periphery of such bar, and is also provided with an escapement-wheel 63, operated in any suitable manner.
