WALTER J. PASINSKI, OF DETROIT, MICHIGAN, ASSIGNOR TO BURROUGHS ADDING MACHINE COMPANY, OF DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN.

ADDING-MACHINE.

To all whom it may concern:

Be it known that I, WALTER J. PAsINsnl, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Im rovements in Adding-Machines, of which t e following is a description, reference being hadito the accompanying drawin s, forming part of this. specification.

y present invention' relates to adding machines of the general type disclosed in my prior Patent No. 1,023,168 of April 16, 1912, and the Horton Patent No. 1,016,501 of February 6, 1912; and consists mainly in a novel construction, combination and arrangement of parts whereby the length of the columnactuators or operatin levers of the machine may be materia y reduced, and the machine as a whole he correspondingly shortened up, as compared with prior machines of this class, without decreasing the range of movement of such actuators or levers or interfering with the accurate and satisfactory operation of such machines as heretofore constructed. This I accomplish by mounting each of said actuators or levers upon a vertically movable pivot or fulcrum and causing said fulcrum to be depressed with the lever as the latter is rocked upon such fulcrum by the operations of the keys of the machine, as hereinafter described.

In the accompanying drawings, Figure 1 is a vertical section of a machine embodying my invention, showing the operating parts of the machine in elevation; and Fig. 2 a corresponding view with one of the operating keys depressed to its limit of moyement. The same letters of reference are used to indicate corresponding parts in both views.

Inasmuch as the general construction and mode of operation of machines of this type is disclosed in the patents heretofore referred to, as well as in various prior patents, the present specification will be confined to a description of the novel features of construction and operation constituting my present invention.

Heretofore, in machines of this class, the column-actuators or operating levers of the machine have usually been pivoted or fulcrumed upon a fixed rod or support at the extreme rear end of the machine, some distance in the rear of the-keyboard of the machine, and have extended thence to the forward part of the machine where they co- Specication of Letters Patent.

operate with the accumulating mechanism. ln prior constructions, having the operating levers so mounted, it has been necessary to employ levers of such extreme length, relatively to the length of the machine as a whole, in order to provide the desired range of movement for the front ends of the levers, for their proper cooperation with the operatingV keys and the accumulating mechamsm, and the result has been that the machine as a whole has had to be made of considerably greater length than was necessary for the accommodation of the other mechanisms of the machine. This necessity is entirely overcome by my present invention, which permits the levers in question to be made of approximately the same length as the keyboard of the machine, and the latter to be correspondingly shortened up and reduced in size, as will now be explained.

In the construction disclosed in the drawings, each column-actuator or operating lever A is pivotally supported or fulcrumed at its rear end, at a, upon one arm of a bellcrank lever B which is mounted upon a fixed cross rod C supported in the framework of the machine. Near its forward end the lever A has a slot-and-pin connection, at l, with one arm of a bell-crank lever D which is mounted upon a fixed cross rod E supported in the framework of the machine. The u wardl and forwardly extending arms, and of the bell-crank levers B and D, are connected by a link or bar F, which in the present instance constitutes a stop-bar for limiting the movements of the parts under the operations of the different keys, as hereinafter described. The forn'ard bell-crank to whose arm D the front end of the bar F is connected carries the gear-toothed sector or rack G which meshes with the pinion H ofthe accumulating mechanism, and a coiled spring l connecting the rear end of the lever A and bell-crank B with a cross rod c at the top of the machine serves to yieldingly hold the parts in and return them to their normal position. Each of the levers A is provided with a segmental slot (l for the accommodation of the cross-rod C, said rod extending transversely across the machine through the slots d of all of the levers A.

The operating keys J of the machine, which are arranged in the usual denominational rows extending from the front to rear of the keyboard, are provided immediately above the lever A with laterally extending lugs f which overlie the upper edge of the lever A and serve to depress the latter when the keys are depressed. The reduced lower ends ol' (he keys J are surrounded by coiled resetting springs 1r/ confined between the shoulders formed upon the keys et the upper ends of such reduced portions and the horizontal frame-plate /iy through which the lower ends of the keys pass and in which they are guided.

Under the foregoing construction and arrangement of parts, when any key in any one of the denominational rows of keys is depressed, :is in the case of the -lrev in Fig. 2, its lug f will contact with the upper edgeof the lever A and depressthe front end of the latter, rocking it upon its pivotal support or fulcrurn a :Lt its rear end. Such downward movement of the front end of the-llever'A will be communicated, through the bell-crank D, D', and link or bar F to the Ybell-crank B, "B, with the result that the latter will be rocked upon its fulcrurn C and the pivotal support or fulcrum o, of the 'lever A be lowered. The proportions of the parts are such, in the present instance. that such pivotal support or ulcrum of the lever A will be lowered to such an extent` relatively to the depression of the front end of the lever, et the operatoniof any key, lthat the lever will be given substantially the same movement as a whole as it would be if it were extended rearward of the keyboard of the'maehine and supported at its rear end upon a fixed fulcrum or pivot A as in the machinesof the prior patents beretofore referred to. The mountings of the lever A upon n. vertically movable support or fulcrum, in the manner described, there fore enables the lever to be very materially shortened. as com-pared with the necessary length of the levers in the prior constructions referred to, while preservingr snbstalntially the same movement of the portion of the lever which underlies ihe kevboard of the marhine and is directly acted upon b v the operating keys.

The depression of the lever A :1nd the roekinpr of the bell-cranks` in the manner described` will of course put the spring l under inrreased tension. and when the operated key is released said spring will restore the parts to normal position. The gear-toothed sector (l will be reciprocated buck and forth at each of such operations. to an extent determined by the particular key operated, and serve to transmit the movement of the parts to the accunnilatinry mechanism, to add the value of the operated key upon it. The accumulating mechanism of the machine may be of any suitable eher acter, that illustrated or indicated in the drawings elnbmlyintgT a ratchet-aiid-paul and gear connection between the pinions ll which mesh with the sectors G and the numeralfwheels Hf, under which the latter are advanced at the return movement of the parts in accordance with the values of the operated keys.

#lo far as the operation above described is concerned, the link or bar F might consist of a simple linlrconnectingl the vertical arms of the two bell cranks, but in the present instance it also ser-ves as a stop-har to positively limitvthe movements of the parts under the operations` of the several keys, to which enditis provided with a series of rearwardly facing shoulders-z' adapted toco operate with lu'gs j projecting laterally from the si'deswof thef key-stems slightly below the top 4plate-ofthe easing of the machine. The adjustment-and relation of the parts aresuchf-thatvihen any key is depressed to its limit of vmovement the corresponding shoulder lnponthe bzlrlF will, in the rearwar'd movement of saidwb'ar, contact with the orvvairdfside4 of thelug j upon the said key,fimd the latter will-.actas a stop to arrest=the movement of the bar F and the parts counectedfwvith: it, as fin the instance of the depression ofthe -key shown in Fig. 2.
