CARRYING MECHANISM FOR CALCULATING-MACHINES AND LIKE.

I '0 all whom it may concern:

Be it knowntliat I, DANIEL W. SHIEK, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Carrying Mechanism for Calculating-Machines and the Like, of

ried to the'next higher order and is there 1 indicated. For example as the indicator of the lower order reaches a total of ten, in decimal notations, one is carried to the next higher order and there indicated.

The object of my invention is to produce eliective and accurate means for the purpose stated.

To this end my invention consists of the novel construction, arrangement and combination of parts shown and described and more particularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like or corresponding parts; Fi 'ure 1 is a. plan view of a calculating or adding machine containing my invention. F ig. 2 is a side elevation of the same with the side plate and a part of the operating mechanism removed, showing a part of.

the mechanism of the lowest numerical order. Fig. 3 is a similar view showing the relative position of the parts when a key of the order isdepressed. .Fig. "i' is a similar view of one of the higher orders, with the key cont-rolled mechanism and connections therewith, and also my improved carrying mechanism.

Specification of Letters Patent.

11 is a section on line 1111 of Fig. 10, showing also the companion or cooperating part of the transmitting member. Fig. 12 is a similar view on line 12-12 of Fig. 10. Fig. 13 .is a view taken substantially on line 13-43 of Fig. 9; and Figs. 14, and 16 are detail views.

The first seven figures of the drawings illustrate the key mechanism and associated parts of an accounting machine substantially the same as that shown in an application filed by me on January 11th, 1906, for improvements in computing machines, Serial No. 295,670.

As shown, 1 is the frame of the machine, 2 the key board provided with a section of keys 33 'for each numerical order. The stems t of the keys extend through the key board and down into the machine and are provided with stops 5, and 6, for a purpose hereafter described. Ieneath the key board is a pair of substantially parallel bars't', and 8, connected by bell crank levers 9, and 10, tending-to keep the bars parallel to one another during their operation and to give the lower bar 8 a forward swing. Resilient means such for example as the springs 11, are provided to return the bars together with the key operated and their associated parts to their normal positions. This may be aided also by any other suitable means, for example by one or more springs 12, secured to one of the hell crank levers and to the frame of the machine. A link 13 connects the bar with a spring latch 14; which coacting with a resilient pivotal detent 15 prevents the rcstoration of the parts to their normal positions until the key has completed the limit of movement allowed in its stroke. A latch 16 is also operated by the movement of the bar 8 for a purpose hereafter described. A spring 17 is provided to restore the latch 16 to its original or normal position. pivotally supported bar 18 (Figs. and T) is operated by the forward movement of the bar 8 and is connected by a link 19 with an arm or lever 21) carrying a pawl 21 arranged to engage the periphery of the gear-wheel 22. pawl 23 o crating in the opposite direction engages t e gearwheel 22 and prevents any back movement. The bar 18 is provided with a stop 24: arranged to cooperate with the latch 16 to retain the bar in its normal position until the, spring 11 is properly tensionedandthe opsubstantially in the'form of a bell crank le-' ver, with one end extended in line with a stop'26 carried on the bar 8,'clearly illus trated in Figs. 2, 3 and 4. The swinging arm or bar 18is also provided with an offset part 27 (see Fig. 7) which extends between the ends of the spring 11 as shown in Figs. 2, 3 and 4, thus as the free arm of the bar 18 is held against movement by the enwheel.

gagement of the latch 16, with the stop 24, the depressing of the key swings forward the bell crank lever 10 when the engagement of the pin 32 with the other leg of the spring 11 tensions the said spring storing sufficient energy to operate the bar 18 and its connected parts when the key reaches the proper point to cause the release of the. arm 18 from the latch 16.

A series of bell crank levers 28 are provided for the keys each provided with a camface 29 by means of which the bell crank will be operated by the contact of the stop 6 of the particular key depressed. By this operation the other arm of the bell crank lever will be swung out of its normal position and in line with a stop 30 on the longitudinally movable bar 31, which is supported by slot and in connection 33, 34.

A link 35 connects t e end of the bar 31 with a bell crank lever 36, 37, pivotally supported upon the same center as the gearwheel 22 with the arm 20. The latter arm 37 carries a stop 38 arranged to co-act with the pawl 21 in operating the gear-wheel 22. The arm 20 is provided with-a projecting pin 39 positioned between the arms 36, 37,

of the bell crank for a reason which will be hereafter stated. In the operation of the mechanism just described, the swin ing forward of the arm 18 brings the paw L2l into engagement with the gear-wheel wedgin the same between the stop 38 and sai The continued forward movement of the,arm 18 thus rotates the gear-wheel 22 a distance permitted by the movement of the bar 31 w ich again is regulated by the stop constituted by the bell crank 28 of the particular key 0 erated. When the parts reachtheir limito movement and the key is released the various resilient connections restore the several parts except the gear-wheel 22 to their ori inal positions during which the. stop 39 on t e arm 20 engage's the arm 36 of the bell crank thus forcing the longitudinally movable bar 31 back into'its normal position.

' A'longitudinally movable-bar 40 (Fig.5)

is provi ed withextensions 41 in line with the bell crank sto s 28, arranged to en a e the notches 42 int e end of sa d stops. e

projections 4343 spaced" from one another to enga e the opposite sides of the cam lever 44 whic 1 is pivota-lly supported between its ends at 45 with its opposite end loosely enaging a part 46 on the bar 40. As a key is t epressed, therefore, its initial movement causes one of the pins 5 to. depress the bar 7 and one of the extensions 6 on the key stem to engage with the cam 29 on its bell crank lever 28 thus depressing theopposite end of the bell crank lever below the level of the stop 41. The continued movement of the key causes the extensions 43 to operate the cam lever 44 longitudinally moving the bar 40 causing the extensions 41 thereon to engage the notches in all of thetother stops 28 so that until the operated key reaches its limit of movement and is released, no other key in that section can be operated inasmuch as they are all locked by the mechanism described. The' reverse movement reverses the action of the cam lever 44 and restores the movable bar 4O to its normal position.

As before stated the parts heretofore described are included in the above mentioned pending application and are not claimed 1 erein except in claims in which they may be included as elements of the combination with the parts hereafter described. v

The novel means for transmitting the movement of the drivin member or wheel 22 to the indicator, and o the carrying from a lower to a higher'order are substantially as lUl) follows. As clearly shown in Figs. 10, 11 and 12 two gear wheels 47 and 48 are placed I ment to anidler 50'and thence to a inion r 51 actuating an indicator 52. In the rst or lowest order it is obvious that an ordinary pinion may be. em'ployedto transmit the movement of the driving pinion to the idler 50, since nothing is carried to it from a lowerorder. All others, however are provided with the double transmitting member and the carrying mechanism therewith. The pinion or member 47 is referably provided with a sleeve 53, secure thereto or integral therewith and a collar 54 slidably mounted on saidsleeve. The collar-54 is constructed with two circumferential grooves 55, 56. A'bell crank lever 57.58 is pivotally supportedat 59 on a lug.'60 formed on t e pinion 47 with one arm 57 bifurcated and positioned in the roove 56 and the other arm 58 extended t rough a slot 61 in the pinion and engaging a s iding reciprocating yoke 62 carried on the opposite face of the pinion. As shown (Fig. 10) the yoke 62 is provided with slots 63-63 within which pins 64 64 on the pinion are positioned. In the preferred construction the yoke is also constructed with an enlar ed central slot 65 loosely embracing a gni ing extension 66. Obviously the parts may be reversed ifpreferred and the functions mentioned retained. A lever 67 is pivotally supported between its ends on each side of the yoke with one end extended to and pivotally engaging the adjacent side of the yokeand the other end provided with a spring pawl 68 off-set to engage an internal ratchet ring 69 or equivalent part carried on the companion member 48, of the transmitting device. The pawls extend in opposite directions andthe reciprocation of the yoke thus causes the pawls to alternately engage the ratchet ring and thus periodically move the part 48 in one direction in relation to the part 47. Stop pins 7 0 or equivalent devices are suitably positioned upon the member 47 to limit the advance movement of the pawls and thus measure with exactness the movement of the part 48,

u in relation to the part 47, at each movement of the yoke. overthrow of the two parts and to positively lock the parts 47 and 48 together at measured points to operate as a unit until the reverse movement of the yoke, when the part 48 is again advanced in relation to the part- 47 and they are again locked together to operate as a unit. Obviously the advance movement of the part 48 will be transmitted at once to the idler and thence to the indicator, the operation being regulated to ad vance the indicator a suihcient distance to register theamount carried from the lower order. I

The idler 50 of all the orders except the last or highest is constructed with a sleeve 71 having fixed thereon two substantially elliptical cams72-73 arranged to extend at right angles to each other, with a disk 74 positioned between them. The said disk has formed in its periphery four transverse slots 75, positioned to register with the longest diameterof the two cams 7273. A rock shaft 76 is located beneath each disk 74 (Figs. 4, 8, 9, 18, 15, 16) providedwith an oscillating arm 77 having at its free end'a transversely projecting pm or finger 78- adapted to readily pass through the several slots'75 in the disk'74. The rock-shaft 76 is also provided with an oppositely extending arm 79which'at its free end is bifurcated and positioned in the slot 55 of the collar 54 heretofore described. (Figs ll, 12 and 13). A cross piece or arm 80 is also carried by the They also serve to prevent,

rock shaft extending at right angles to the arms 7 7 and 79, with its opposite ends resiliently connected to levers 81 and 82 pivotally connected to a fixed part of the device with the free ends extended to the cams 7273 andarranged to ride thereon. As shown the ends of the said levers or arms are provided with anti-friction rollers 83-84 ridlng upon said cams, while coiled springs 85-85 serve to connect the said levers to the cross arm 80.

It will be apparent that the gradual rotation of the idler 50 and the connected cams 7273 will alternately oscillate the levers 8182 in opposite directions to one another and that the tensioning and release of the springs 85-85 will also be alternate and in opposition to one another thus actuating the rock shaft 80 and tending to oscillate the arm 77. The pin 78, however, rides upon the side of the disk until a slot registers therewith at which moment the maximum tension is 011 the spring actuating the rock shaft. The pin being unobstructed readily passes through the slot thus allowing the rock shaft to operate .the actuating lever 7 t), thus moving the collar 54 longitudinally on the shaft 49, operating the bell crank lever 57-58, the sliding yoke 62, the proper pawl 68 and moving the part 48 forward in rela-' tion-to the part 47. This train of operations is timed to take place at the moment the next lower order has reached the point when the carrying is to be done, for example when a ten is to be carried 'to the proper order.

It is clear that the operation described will take place with substantially the same exactness" and accuracy whether the transmitting members 47 -48 be then moving in movement of the mechanism of the higher orders. It is obvious therefore, that keys in several orders may be simultaneously 0 erated, thus greatly increasing the spec at which the machine may be manipulated.

resppnse to the actuation of a key, or whether The indicating mechanism may be as preferred, As shown in Fig. 4, the indicator is the same as that shown and described in said prior application for Letters Patent. As thus arranged the indicator pinion 51 has secured thereto or made inte a1 therewith a ratchet wheel 86, the two belng loosely mounted on a shaft 87. An oscillating arm 88 carrying upon its free end an indicator segment 52, is provided with a bell crankhooked pawl 89 for the'ratchet wheel 86 ivotally supported between its ends with the free end 90 extended to contact/with astop 91 to release means limits the return of the indicator to its normal position. The indicating characters on the part 52 are shown through a sight opening 94 in the case. The shaft 87 extends from the casing (Fig. 1) and is provided with a suitable knob or button 95 by means of which it may be rotated in re-setting the device. The shaft also has fixed thereto for each wheel 51 a ratchet wheel 96 co-acting with a spring pawl 97 on the ratchet wheel 86, by means of which upon rotating the shaft the ratchet wheels 86 and the associated wheels 51 are engaged carrying the several indicators up in unison to the point where they are simultaneously released resetting them all at the zero point, the several associated parts being capable of such movement for the purpose stated.

It is obvious that after describing my improvement, various immaterial modifications may be made without departing from the spirit of my invention. Hence I do not wish to be understood as limiting myself to the exact form and construction shown.
