COMBU'l-ING-MACHINE.

lbv all 'whom 'it cloacem:

vBe. it known that I, GUsrAvE O. DEGENER,

a citizen of the iUnited 'States,.residing in `NewYork cit in the vcounty vof'NeW York ew York, liave invented cerjputingfMachines, of.which the followingis a specification. l d This invention relates to the tens-carryinginechanisinof computing devices, particularly those offthe kinddisclosed -in the applications of -l-Valter VIight, No. 185,046,

tiled March 22,- 1909,.anclfl\o. 543,693, tiledv -February '.12 1910, in which a constantlyv v revolving device i is called' upon inter- 'f- Amittentlyto assist incarrying tens from one computing wheel to the next. As 'set forthfi'ii said app1ications,.each main computing '.wheel. is provided' with a special tooth,

' 20' whicl i turns a pinion that in mesh with 'the Vcomputing wheel of next- 'higher de- "poin-ination, toi `the end that said' higher' tcomputing-,n'fheel .may make one-tenth of a revolution- The movement of this tensl carrying piiiionis Vassisted by a constantly 1. revolving soft-rubber roll; the pinion having as'et of points 'or lobesl to engage said rollito be Vturned thereby, whereby sutlicient assistance to the tens-carrying pinion as- Surfed.

The object of the present invention is to -improve the construct-ion and operation of thetens-carrying devices, with' a view to in- `cre se 'the speed and reliability of action,

S5 and prolongthe life'of the parts.

' According' vto thepresent im rovements, in place of the soft-rubber rol aforesaid, there is employed a set of yieldingly .mounted pinions having line teeth adapted 40 to engage teeth-provided upon the -assisting lugs lixed to vthe aforesaids'tenscarrying pinion. Normally,=the constantly revolving pinion is out of mesh with vthe teeth on said assisting lugs; but at the proper` time the movement of the main computing wheel .will cause one of said assisting spurs or l Vlugs to mesh withthefconstantly revol'ying pinion', whereby; the latter is enabled tof assist 'in the turning ofthe tensfcarrying' 5 0 pinion. ASince the constantly revolvingpinions f areyielding'ly mounted, they Vare sure to' mesh properly `with the teeth of the aforel said assistin-1u'gs, since they will yield if I the lug teet -are improperly presented to theiil. r

F ig. 6 -is a plan of the devices seen at .Fig.'2. Fig. Tis a perspective view, show-- in g the opposite side of the device se'eiiat F 5. Fig.' 8 is a 'perspectiveview-'of a primary computing wheels Fig'. 9 is a-part-, sectional 'plan of the computing devices. Fig. l0 is an' elevation of the constantlyievolving tens-carrying. pinion, showing in v.section the yielding support upon which it is' mounted. liig. 1l is a view' similar, to Fig. 10, but showing the pinion mounted upon a revolving support which is square m cross section; this being the preferred form of the invention. Fig. 12 is a separate View' of the pinion seen at Fig. 1l.

Each .primary computing wheel'l is inthe form 'of a gear inI mesh with a gear 2, the latter fixed upon a number Wheel 3. AEach computing wheel l has a series of ten interior notches 4;, whereby it is rotated. The rotation is effected by an interior master wheel 5, having opposite teeth 6 working in the notchesl 4;; said master wheel fixed upon a shaft 7 rotated by a gear 8. Intermittent variable rotation ofthev gear Sis effected o r controlled by keys in any suitable manner, as for instance in the manner illustrated in said applications. The gangs of computing and number Wheels travel step-by-step, to enable the master wheel 5 to operate consecutively upon the primary computing wheels 1,. as set'forth iiisaid a plications.

Once in each revolution of eachprimary computing wheel 1, a special tooth 10 thereon, sets in motion a tens-carryingpinion 11, which is in mesh with the primary wheel l of next higher denomination, whose diameter is twice that of thepinion; said pinion being provided forthis'purpose with a set of five equally spaced Aprojections 12. 'en- 10 pinion .11 iid of thev nexthigher computing wheel l'is'a'ssisted or in part effected by one of a series of constantly revolving auxiliary pinions 13; the pinion 11 being provided,

. Vfor 'this purpose, with a series of ive spurs or lobes 14,. forming an auxiliary Wheel; the tipsof the lobes or points 14 having teeth 'orfserrations 15 to match those ofthe pinion 13. A'detent roll 16 is seated in one of -five notches- 17 .between the points or lobes 14. {Said roll 16 is carried on an arm 17, pivoted at 18, and held by a compressionfspring 19, occupying a fixedftube or housing 20 and having a screw adjustment. The movement of the tens-carrying pinion 11 originally effected by the special tooth 10 of the computing Wheel, is sufficient to bring a point or lobe 14 into mesh with the auxiliary pinion' 13. Since the latter isv in constant motion, it ivill operate to drive the pinion 11 positively in the same direction i until the latter completes its movement through one-fifth of a revolution. The movement of the tens-carrying pinion 11 is completed by said detent roll 16, and the teeth 15 are 'carried out of mesh with 13, the latter normally occupying one of the recesses 17 as shown. The pinions 13 are spaced at intervals along a constantly revolving shaft 22, extending along the'g'ang of tens-addingl pinions 11, said shaft constantly rotated by any suitable source of power as set forth in I said applications. The-shaft 22 is preferably square or prismatic in cross section,.

and has a soft rubber covering 23 in the form of a tube, square in cross-section; the pinion 13 having a square central hole 24,

. vto tit upon the cushion 23. This member 23 is of such consistency or Athickness as to yield very easily, so that, when the first of the advancing teeth 15 on the star or Inutilated Wheel is struck by one of the teeth of the 'revolving pinion 13, the latter is enabled to yield, in order to prevent injury to the teeth. and also to prevent the teeth from becoming inter-locked, and to insure that the pinion 13 will mesh properly with thc teeth 15. The square. or prisiniitic form of the shiitt und the cushion thereon, to

vvwhieh'the square' or non-circular central perforntions 24 in the pinions are fitted,

insures thiit the pinion will nli'vnys he positively rotated without liiihilitv of. injiii-.vuoti'he cushion and withoutintei'tering with the Ayielding 65 action of the pinion.

by the shaft und its cushion,

'carrying device In the form' of the invention shown at Figs. 3 and 10, the pinion' 13 is mounted? on a round shaft 25, corresponding with 22,

and having a round tubular soft rubber tube ,26 secured to the shaft and to the pinions,

which have round bores to fit on said cushion. 4 .At Fig.' 3, the pinions 13E* are separated by vyashers 27 at intervals to agree with. -the se aration o f the star wheels .14; and it will be understood thatl the pinions 13 may.

4be similarly separatedby .ring washers 28, 'Fig.111,
