ADDING MECHANISM.

To all whom it may concern:

Be it known that I, FREDERICK L. FULLER, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Adding Mechanisms, of which the following is a specification.

My invention relates to adding mechanisms, such as are used in calculating machines, cash registers, and analogous constructions, and has for its object the production of a simple and positively operated mechanism, adapted to the addition of selected numerals.

In the accompanying drawings, forming a part of this specification, I have illustrated my adding mechanism or counter in 'connec tion with sufficient means to operate the same. Such illustrations as I have given show that part of an ordinary adding machine embodying my construction, which is sufficient to fully illustrate my invention, but without the inclusion of other parts of such a machine which are commonly used to indicate and register or record the results of the operation of the mechanism.

In the drawings Figure 1 shows a top view of a calculating machine embodying my invention, a part of the case being broken away to disclose portions of the mechanism within: Fig. 2 shows a side view of a portion of a calculating machine containin my invention, with a part of the side oi the case broken away: Fig. 3 is a detail view showing one form of a driving mechanism for operating the adding device, being an end view of said operatingdevice and the connections: Fig. 4 represents a longitudinal view of the main or actuating shaft of the driving mechanism with a central longitudinal sectional view of the driving sectors and their hubs, and the 'cam wheel used to throw the adding mechanism into position for action: Fig. 5 is a detail plan view of a portion of the adding mechanism: Fig. 6 is a sectional view of the mechanism shown in Fig. 5: Fig. 7 is an end view of the addin mechanism or counter with one of its en frames removed: Fig. 8 is a similar view to that shown in Fig. 7, but illustrating the parts in different relative Specification of Letters Patent. Application filed August 13, 1909. Serial No. 512,628.

Fig. 9 is a plan view of a complete section of the adding mechanism: Fig. 10 is a plan view of an actuating detent and its secondary cam, and another of said detents and secondary cams shown in section: Fig. 11 is an end view of the adding mechanism with one end frame removed showin the parts of the mechanism in a position di ferent from that shown in the preceding figures: Fig. 12 is a view of the parts shown in Fig. 11, but in a yet different position; and Fig. 13 is a front view of mechanism used in the final operation of addition, and in releasing the adding mechanism for renewed action of its parts.

My construction is so arranged that'the desired numbers can be selected, indicated and added or totalized, and the means for accomplishing this I shall now describe.

In Fig. l I have disclosed my adding mechanism proper in connection with one form of mechanism for operating the same, but it will be understood that the adding mechanism itself can be combined with a variety of means for producing this result; In the particular construction which I have illustrated in the drawings the apparatus is inclosed in a case 1, the top or cover of which contains nine slots 2, 2, four of which are shown in Fig. 1. Beside each of these slots, or between each two thereof, are arranged the numerals from naught to nine inclusive, as shown, to guide the operator in the manipulation of the machine. Operated through each of said slots is a knob or handle 3,'with a pointer 4, to guide the eye to the desired numeral on the case. Each of these knobs, 3, is attached to a rack, 5, which slides within the case of the machine, and is shown in Figs. 2 and 3, each of which racks, 5, meshes with a segment 6, mounted loosely on the actuating shaft 7. Rigidly attached to the shaft 7 are the arms 8, to the lower ends of which is fixed the rock shaft 9. At one end of said shaft 7 is pinned the operating lever 10, which is shown in its normal position in Fig. 2. Loosely mounted upon the shaft 7 is the cam wheel 11, which has live cam surfaces equally spaced on its periphery, also fast -to the shaft 7 is the arm 12, upon which is mounted the spring pressed plunger 13, which bears constantly against the edge of the cam wheel 11, and partially rotates the same when the operating handle 10 is moved. On the shaft 14, journaled at its ends in the sides of said case of the machine, are mounted the endframes 15, which contain th adding device proper. Mounted on the right hand endframe, 15, is the roller 16, which contacts with the cam wheel 11. rigidly attached to each end-frame, 15, is the shaft, 17, on which are loosely mounted a series of indicating disks, 18, hearing the numerals on their peripheries, to each of which indicating disks is rigidly attached a gear wheel 19; and it will be noted that said several disks are spaced from each other and retain their relative positions by means of thehubs 20. Higidly mounted in said endframe, 15, is the shaft, 21, parallel to the shaft, 17, and below the same. On said shaft 21 are loosely mounted a series of actuating detents, 22, of anchor or pallet formation corresponding in number with the indicating disks. Also loosely mounted on said shaft 21 is a series of secondary cams, 23, corresponding in number with said actuating detents, 22, and alternating therewith.

Rigidly mounted in the end-frames, 15, is the shaft 24, on which are loosely mounted a series of detents 25, corresponding in number with said secondary cams 23, and respectively held in contact therewith by the series of helical springs 26' which serve to hold said detents 25 and actuating detents 22 in their normal positions, and return them thereto after action. Rigidly attached to the shaft 14 are a series of spirally arranged primary cams, 27 one less in number than the indicating disks, 18, and respectively positioned in the paths of the corresponding secondary cams 23. On the left hand face of each of the indicating disks, 18, and opposite the numeral 4 on the periphery thereof, except on the extreme left hand indicating disk, is fixed a stud, 28, which in its path contacts with the secondary cam, 23, next to the left of the disk, 18, on which said stud is placed. On the left hand face of each of said secondary earns, 23, is fixed a stud, 29, which projects perpendicularly from the face of its cam, 23, and under the actuating detent, 22, with which it may contact. (See Figs. 7, 8, 11 and 12). Rigidly mounted on the shaft, 7, near the left end thereof, is a geared sector, 30, and rigidly attached to the adjacent side ofthe case of the machine is the stud 31. On this stud 31 are revolubly mounted the pinion, 32, and the eccentric 33; and to the said eccentric is strapped the rack, 34, which meshes with the pinion, 35, rigidly fixed on the shaft 14. Fixed to the pinion, 32, is the disk, 36; while fixed to the eccentric, 33, is the sleeve, 37, having a transverse notch in Mounted on andv the lug, 41, on the outside of the case. this motion of the said lever the cam-wheel 11 is turned one fifth of a revolution, and

suming the several parts of the machine to be in the primary or normal positions, shown in Figs. 1 and 2, the zeros on the peripheries of the several indicating disks, 18, are visible through the openings 40 in the :case, and the several knobs, 3, and their pointers, 4, are below the zeros marked ex- .ternally upon the case.

To select and add anynumerals, the desired numerals in units,

tens, or hundreds are determined by moving the proper knobs, 3, until their pointers respectively stand opposite the several selected numerals as indicated on the case.

As each of-said knobs, 3, is moved forward to its position opposite the selected numeral, the rack, 5, to which said knob is attached is moved the same distance, and the teeth on such rack meshing with the teeth on the particular sector, 6, to be actuated by said rack,

turn back the said sector as many fiftieths of an entire revolution thereof as there are units in the numeral selected. The several knobs, 3, having been brought opposite the selected numerals indicated on the case, the lever 10 is thrown forward from its normal position indicated in Fig. 2 one-fifth of a complete revolution, when it is stopped by y the roller 16 is forced up upon the periphery of said cam-wheel, whereby the endframes 15, are rocked upon the shaft 14 so that the gear-wheels 19 are brought into ganes with the several make 5 which have been moirl from their normal positions; the rock smart 9 contacts with and drives forward the previously operated sectors 6. which being constantly in mesh with said racks 5, operate to return said racks to their normal or primary positions by the time the lever 10 contacts with the stop 41 (see Figs. 2 and 3); and simultaneously the meshed gear-Wheels 19, and their related disks 18, are turned one-tenth of a revolution to each unit of the numeral on the case indicated by the pointer on the knob 3 on the related rack 5. Simultaneously with the completion of this operation the roller 16 drops into the next cam on the cam-wheel 11, and allows the end-frames 15 to drop, thus removing the gear-wheels 19 from contact with the racks 5. When any gear-wheel 19 has forced to a complete rotation-by the motionof its related rack 5, the stud 28 on the related disk 18 will have come into contact with the related secondary cam 23, and said secondary cam 23 is brought into the position indicated in Fig. 8, the related detent 25 catching in the second notch in said secondary cam 23, and holding the projecting cam of said secondary cam 23 in the path of its related prim "ry cam 27 mount ed on the shaft 14. (See Fig. 8.)

' On the forward movement of the lever 10,

the shaft 7 and the geared sector 30, mounted thereon, are turned one-fifth of a revolution, and the related inion 32 is turned one complete revolution, ut the pawl 38, being thrown out of the notch in the sleeve 37, the eccentric 33 does not rotate, and, therefore, the shaftl'i and its prima cams 27 do not rotate. When,however, the ever 10 is thrown 1 back to its normal position, and the sector 30 is drivenupward one-fifth of a revolution, and the pinion 32 is turned one full revolution, the pawl 38 catches in the notch in the sleeve37, and the eccentric 33 is forced to a complete revolution, and its related rack 34 meshing with the pinion L 5 forces said pinion 35 and the shaft 14 with its primary cams 27 to one full revolution forward, and

one full revolution backward. In the forward revolution of said rimary cams 27 those of said cams 27 which are related to such of the secondary cams 23 as are projected into their respective paths, force the said secondary cams 23 down out of their paths, bringing the noses of the related detents 25 out of the notch in the said second ary cams 23, and driving the studs 29 fixed on said operated secondary cams 23 against their related actuating detents 22, and said actuating detents move the indicating disks 1'8,to which they are respectively related forward one-twentieth of a revolution (see Fig. 11.) As the shaft 14 carryin the primary earns 27 completes its forwar rotation, the cut out portions of said cams will be presented to the operated secondary cams 23, thereby permitting the springs 26 to return the operated detents 22 from the position shown in Fig. 11 tothe position shown in Fig. 8, during which movement the disks 18 garimary positions shown in Figs. 2 and 7. id secondary cams 23 thus remain out of are respectively oroed in their. paths again by the operation just described.

In an operation of the machine where a transfer is caused by a transfer, such for inat 9 and 1 is added to the disk of lower order, it is necessary that the. secondary cams 23 be positioned to effect a transfer durin the one-twentieth of revolution imparte to the disks by the movement of their related detents 22 in an anti-clockwise direction, Fig. 8, because of the fact that the last half of the transfer movement is imparted after the shaft 14 carryin the primary cams 27 has completed a fu l rotation in a clockwise direction, Fi 8, at which time it would be too late to initially set the seccams would be reset during the reverse rotation of the shaft 14 by the primary cams 27 carried thereby, consequently losing the transfer. It will thus be seen that by the construction described and shown and the proper proportioning of the various gears on racks, sectors and pinions the indicatin disks 18 are turned as desired, and as eac peripherally numbered disk completes a revolution the adjacent disk indicating the next higher denomination of units is rotated to the extent of one figure, and the adding proceeds regularly and surely with the operation of the machine.

As hereinbefore stated I have shown and described only my invention and such parts of a mechanism adapted to operate the same as I deem requisite to enable those conversant. with the art to make and use the same, giving no description of the means necessary to record or visibly indicate the various summations effected by the apparatus; such parts of a complete mechanism constituting a calculatin machine, or indicating register of any ind, to which my construction may be applied, forming no part of my invention or being necessarily shown or described with it to convey a full understanding of the construction and use of my invention.
