pplieetion tiled Hoven* To all whom i? may con-ce Be it known that i, FRANK Warren; citizen of the United residing at Detroit, .in the county of Vitayne and 'there ot Michigan, have invented useful lmprovemei iu Adding ldachin of which the following is a specification, erence being had therein to the accon panying drawin Ther invention relates to adding-me and it consists in the novel constru rangement, and combination oi" parts', hereinafter set fort-h,

. In the drawings, Figure i is a crosssectio through the machine. Fig. 2 is a den' view on line :ras, Fig. l. F 3 is a pers-p0 tive view of a portieri of the carrying mecnanism. Fig. is a front elevation of the machine.

A. represents the counters, which are p1 iierably in the form of Wheels sleeved upoi a shaft B, extending longitudinallythrough the case C. As shown, each oi the Wheels provided with a ilange c, on which the dig is are arranged, and the Wheel may be pro ded either with a singleseries of digits equally spaced around the flange or preferably scveral series arranged luccessively. In the construction shown the Wheel termed for four complete series of digits, each occupying a quadrant of the liange.

The counters A .are provi( ed with means for variably actuating the same, preferably consisting of a notched peripheral iiangcl), forming a series of fmgenbearings c adjacent to each oi the digits. The casing C is con: structed so that of digits project outward 'through a slot into turn the wheel. case is provided with a slotted quadrant i), and upon the sections of this quadrana inter mediate the slots, are marked a series otdigits o posite the bearings c. t e counters maybe operated by placinga :finger in the bearing c opposite the proper digit and drawing dowmvard on the wheel g This until the limit oi movement is reached. limit is preferably formed by a ledge der E on the case.

Each of the counters A is provided with a carrying mechanism by which the Wheel of next higher denomination is actuated. This mechanism is not directly actuated by the movement of thecorresponding counter or its actuating means; but the arrangement is and in normal position the bearings c for one series l Thus any one of or shoul- Patented July 10, 11906.

such thateach eoimter controls the carrying to the Wheel ot' next higher denomination, While the cari' uechanism is actuated by l'H the construction shown sf represents o s members tor the carrying mechanisms, cach oi which is arranged ed jacent to and .in iront of the ilange l) on its corresponding con l and extends downward through beW gs on, the case. .ln normal position 'these ak y.ing devices project above the shoulder o that Whenever the corresponding comite is actuated by the engagement of a tin er w1 th. one of the bearings c, the operators hnger will also strike against the actuating device h" before completing the movement. Thus the said member will be depressed simultaneously with the nal movement imparted to the counter.

Each actuating device F has an operating connection With a pawl, which. when operated engages with. the .notched bearings of wl rlhis, as shown, consists of a lever G, iuleru'med upon a crossthe corresponding bar il. The iront end of said lever lies in the path of the lug c, secured to member F,

l thereby arresting further movement of both a position Where they may be c perated to Ls shown, the iront ot the the pawl and the counter-Wheel.

it will be noticed that 1n the mechanism just described the actuating member F ad- IOO d dogs are, however, normally held from such engagement by iingers f oi the levers K, which are pivote-ily secured Within the case have their fingers f projecting between adacent members F, so as to hold the dogs J rom contact with the shoulder e. The fingers f are operated by actuating-arms g, which extend adjacent to the corresponding counter-wheel.-and into the path of lugs or pins L on said Wheelarranged between adjacent series of digits.

Thus whenever one of said pins L by engaging with the arm g moves the finger f out of the path of the dog J which occprs Whenever H9-ap'pears at thel opening K, sai'd dog will engage with the shoulder e of the next higher member F, with the result that the next higher number F will be depressed simultaneously with the depression of the member F corresponding to 'the counter.

` If the number shown through the openings k is 979908, the second, third, fourth,.and sixth arms g counting from the left in Fig. 2 and from the right in Fig. a will be depressed, and the second, third, and sixth members J will lhave been permitted to swine over the lugs e of the next higher mem )ers F. Depressing the fourth-member f F, as in Fig. 2, would cause the iifth member to go down with it,`eausinu the iifth counter to move one step at theimal movement of the fourth counter and its member F. If, instead of the fourth counter being actuated, the sum of two be added to the first counter, thereby turning the wheel and causi'nnr one of its pins L tovdepress its fmgerf, and t ere! by release its dog J, the depression of the member F would cause the units-dog J to depress the tens member F, its dog would de press the hundreds member F, its dog would depress the thousands member F, audits dog would depress the ten-thousand member F. The members F of the units, tens, hundreds, thousands, and tens thousand wouldinove together and their counter-wheels would turn together, and the number shown tlirough the openings lc would be changed from QYQJQS to 980000. All this setting of the dogs J is done as the lowest counter-wheel passes a ligure 9 past the opening r, and as the figure 0 of the lowest counter passes its opening c the tens are transferred.

It is one. ofthe objects of the construction to avoid the use of sprh1gs,which are liable to get out of order and cause inaccurate operation. To this end the pawl I and iinger f are constructed to return to normal position by gravity. The dog J is also actuated by gravity to move into a position for engaging with the shoulder c of the adjacent member F. A ain the actuating members F are re- -turne by the gravity of the outer ends of the levers G and the awls I thereon. More specifically the dog I as its dog' d suiiicientiy wei hted to assume the position shown in fu l lines in Fig. 1. The dog J is provided with the weight 65 pivot h, and the lever has the counteron one side of its weight i thereon for holding and returning it to normal position, where the arm g exLends into the path of the pin L and the end j of the dog has passed below the finger The levers K are preferably pivotally secured upon `the shaft M, which is secured in bear' s N ,to the frame O, in which the members I* are slidingly secured. The dogs J have a runded ortion j for projecting into engagement wit the shoulder e, so that in the return movement of the members F said dogs will be automatically disengaged form said shoulders by again contacting with the Corresponding linger With the mec anis'm constructed as shown and described in operation any one of the counters may be actuated for any number from l to 9 where there is but a single series of digits upon the wheel-flange or where there are four series, as in the preferred construction, each counter may be actuated for any number from 1 to 36. In this movement the counter isi turned the proper distance, and at the end of the movement the member F is operated as before described to actuate its corresponding lever H and pawl I. If the linger f is in normal p'osition, this actuation willnot aifect the a'djacent counter, but if the Enger has been moved bv one of the'pins L out of the path of the dog J it cannot again assume its normal position until said dog and its correspondin actuating member F have been 'depresse As a consequence the pins L may operate the finge'rsat any point in the movement 'of loo the counters; but the carrying will not be effected until the end of the movement, and

when this occurs the finger previously `operated is still in position to permit the carrying. The advantage of this construction is that the counters may always be operated with perfect ease and offer very little resistance't'o the finger until the member E is reached, and the latter may be easily operated, as it is provided with a lat bar for the iinger to 'rest on. pThe result of the addition may be read through a window located at any convenient point in the casing, but preferably arranged in the segmental portion D, as shown at o Vreset the-machine for a subsequent addition, the shaft B is provided at 'one 'end with a crank-armi), arranged outside the ease, and within the case are a series of'arms Qbetween adjacent counters, each of said arms Y I 2O provided with a awl R for engaging wit one of the pins i Thus the operator moving the crank P through 'a quarter of 'a revolution will` engage the tpawls R with the pins `of all the counters a'n'd will move said counters to the zero position. 'Ivhe arm P is then returned to its normal position by a counterwei ht S.
