Gaxcnsn, n citizenoi the United States, botli'resiilents vof the city of New York, borough of Manhattan, in tle county und State of New York, have invented o. new and improved Aclcling-.\laehine, of which the following is a full, clear, and exact description. The obect of the invention is to provide a new and improved adding-machine which is comparatively simple and 'durable in con,-A struction, not liable to easilyget out of order, and arran ed to permit convenient manipulatin wit a view to edd. up any desired numger of sums and indicate the total, 'and more particularly to add sums representing money in dollars and cents or other denominations. Y The invention consists of novel features andV )erts and combinations of 'the same,A as will lie `more fully described hereinafter and then pointed ont in the claims.` I

A practical embodiment of the invention is represented in the accompanying drawings, forming s. part of this specification, in which similar characters of reference indicate corresponding parts in all the vievvs. Figure 1 is a perspective viexvof thev inif of the improvement detached romthe standY and its casing removed. Fie. 3 is areal' f ace view of thesame, the operiert-m -ohains being' removed. Fig. 4 is en enlarge cross-sectionv of the improvenf'ientY on theline 4 4 of Figi?. Fig.`5'is alike view of the same on the line' 5. 5 of Fi' 2.' .Fim 6 is, a 'similar vejw'of 'the same', s owing tie parts in a different.'1 osition. Fig. 'I Y1s an enlarged longitudine seotional elevotion ofthe saine ontheviinelf 7 of Fig. 4.: Fig. 8 is a cross-section ofthe same on the line 8 8 of Fig. 7.. FiV i 9 is a face vien ofone of thodi'sk cams, an: Fig.- 1i)` is a perspective view of oneA of the numerallates.

The adding-machine,- as shown in Eg. 1, is

removably mounted on n-sta'nel A, provided,V

at its 'rear end with a rack B for snp ortingjhiclithe amounts to be gilded are read, they dooti'xfnnts beingxlisplayed to alloue the pperf.; 1to1- to 'convenientlv-read the amounts suc. cessively. "The-kid ing'nmclii'ne is provided with lansingv D, fitting nn inclined retossilil ing is fitted A freine E, in which is journaled a and G,`ench havin# on its eripheral'face the numerals from OPto" 9, thennr'nber-wheel G representingunit cents,the number-wheel G' tens yof cents, and the number-wheels ,G2 G4, G* G", ancLG representin unit dollars, tens oi Y, sands and tensof thousands of dolla'rs.' ft is, however, expressly understood that "the wheels me f re resent other denominations of money esi( es dollars ontleent-s as, men'- tioned. Y Tiie numersl whichr is on the tlopof a wheel at the time is visible throu h a corre,- syonrling'aperture D in the-casing to' allow t i e'operator to read the ag agate amount of the sums added, as hereina scribed. Y y

` in order to turn each number-wheel menually and independently'ofthe others, 'the following device isrovlded. On the hub of each number-Whse G,-Gf, Gl, G, G, G?, and G is secured a sprocket-wheel H, over which passes alsprooketLcliain'H, also' passing over.

If it is desired to add 9 at any of the devices, the tool is engaged with the corresponding chain at the link registering with the numeral 9" of the numeralplateA J, and then the chain ward untill the tool abuts against the lower edge Da of theopening D. The numberwheels turn in the direction of tlie arrow b.'

The nuineral-platesJ for the units and tens of cents are preferably' in contrast to thc adjacent numera lates J forthe units, tens, and hundreds of ollars, and the thousands and tens-of-thousands numeral-plates J are likewise in contrast .to the said units, tens, and hundreds of dollars iiuiiieral-plates, to enable the operator to readily distinguish the several numeralplates with a view to facilitating the use of the machine.

In order to turna number-wheel from a grecedin one whenever the latter moves om 9 to 0, the following device is provided: In each number-wheel G, G', G', G, G, and G is ulcrinied a sidewiseextending awl L, adaptedto engage a ratchet-wheel secured on the hub ofthe next following number-wheel, and-the said paw] L rides on the eripheral face of a disk-cani O, secured to t e spindle F, normally locked a ainst rotation on the frame E, as hereina ter more fully described.- Each disk cam O isA ar- -ran ed toormally hold the correspondin aw L ou't of en agement with the' next'fo ratchet-w eel N, andA each disk -cam O is provided 4with a' cut-out portion O to allow the'pawl L to-xnove into engagement with a tooth oftheratchet-wheel with a vien'r toturnthelatter to rotate the following number-fivheel a sufcient :distance to bring thel next followin'gnuineral into view at the opening D. In orderto causethe p awl L to travelinwardly'onthe cut-out portion-O', a camLann"`Pis Ero'vided, (see Figs. 5 and-6,) registering wit .t l ie cutot'it portion O', and consequently causing the pawl L tofollow the`cut-o'ut `portion and thereby engage a toc lli oftheratch'et-,wheel N with a view to til thc tool is pulled down.

When it is desired to reset 4the machine. it is onlv neeessarv for the operator to nil the knob ll outward to nnloeksthe knob v tlisenrfaginv the pin R from the aperture Ef,- nnd then t te operator turns Vthe knob, and consequently the s indle F, in the. direction ol" theV 'nrroiv b'-t int is, in the direction in' 'whielithe vmunber-wheels turn when the machine is used for adding sums. This rotation ofthe spindle F'catises engagement of thel several an'ls SQso that the number-wheels G,` G*.,' G?, and G are inaily all hrnvht 'ir to Snell o,v position that their nuniern s stand in alineinent, and eonseqnentlt' the operator on further turning of the knol; R and-spindle F an llnnllj; bring the 0" of thelsevernl ,number-wheels to appear in the;

When this has been done, the operator releases the knob R, so

that the'sping R* pushes the knob hack te itsroricfina position-that4 is, en aves the pin R with the opening E to hold t e noh, and jconse nently the spindle F, against turning until t "e machine is again reset, as above described.
