is shown arranged to rotate a shaft represented conventionally at 10, and suitably supported by a bearing 11, the latter supported upon a suitable sta-ndard,or other support, not shown. The lmproved device comprises a shell like structure including a rear disk-like portion 12 having an annular rim 13 secured thereto by any suitable means, for instance by screws, or like fastening devices as shown in Figs. 1, 2, 3 and' t, or'by set bolts 47 as angular supporting members, one of which is shown in perspective in Fig.- 6. The supporting members are precisely alike and are interchangeable within the shell.

Each of the supporting members is'indieated as a whole by the character 15, and

each provided with a projection. 16 extending from the outer edge and the remaining edges beveled, as shown at 17 The supporting members 15 are so arranged that when disposed within the shell their confronting edges ares aced apart to formguideways 18, the beve ed edges 17 of the members 15 forming the sides of the guidew'ays.

7 Four of the members 15 are "employed so that the guideways radiate from a common center, asshown in Fig. 1. Eachof the which engage over ribs, indicated at 20,

:'which project from the inner face of the portion 12 of the shell. The guide-slots 19 and the ribs '20 extend inparallel relation'to each other and at right angles to the outer faces of the members 15, so that the latter are movable toward and away from'the center of the shell and of the shaft 10 and thus control the width of theguideways 18, as hereinafter explained. I

Clamp bolts 23 extend through the memhere 15 and the portion 12 of the shell, and are formedwith countersunk heads engaging in countersunk apertures in the members 15 and provided with clamp nuts 24 bearing against the inner face of the member 12. The member 12 is formed with slots indicated at 25 where the bolts 23 pass throu h, so that themembers 15 may be ad- ,members 15 is provided with guide-slots'19 justed toward and away from'the center of the shaft to any required extent within the range of the slots 25, and thus hold the members 15 in their adjusted position.

Fittin within the spaces between the members 15 and the rim at eachside of the projection 16, are adjusting blocks26, the inner faces of the blocks bearing flatly against'the outer edges of the members 15 and the outer faces of the blocks curved to correspond to the curvature of the inner face'of the rim 13. Operating through each of theprojections 16 is a clamp bolt 27 upon which adjusting nuts 28 are mounted and operate to adjust the blocks 26 toward and away from the projections 16 to cause their outer curved faces to bear against the inner face of the rim 13. 'By this arrangementit will-be obvious that'the members 15 may be adjusted toward and away from the center of the shaft 10 and thus control :the width of the guideways 18, and the-blocks 26-may be-likewise adjustedto hold the members 15 firmly in their adjusted position. The bolts 23 and 27 enable these adjustments to be made, and cooperate to firmly lock the members 15 in their adjustedposition.

Movablydisposed in the guideways 18 are coacting sliding members 29 which are formed; as shown in Fig. 8 with beveled sides conforming to and closely engaging the beveled edges of themembers 15. Each of-the slides is provided with a wrist=pin30. Two of the members 29 are employed and are ofgreaterlength than the width of the guideways- 18, so that the slides will move past the innerterminals of the: guideways and notbe deflected from their paths. connecting'rod comprising a stock portion 31 and ahead portlon 32 forms a part of the im roved. device, the head portion being of Sn cient length to engage both of the wrist pins '30,'as shown in Fig. 1. The head portion' 32 of the connecting rod is formed with transverse-openings"or guideways 33 for the bearing blocks or brasses which engage the wrist; pins, the guideways being-separated by aweb .34. Each pair of the bearing blocks or brasses which engage in theguideways 33 are precisely alike 'and-the description of oneset-or pair willsufiice for both. The

bearing blocks or brasses for each of the openings-'33 are shown in perspective'in the lower, portionof the group of members represented-in Fig. 7 On'e ofthe bearing blocks is represented at 35 and fits'fiatly against the-outer-end-of oneof the-guideways 33 and against the flat inner end of the other guideway33. The other bearingblock or brassrepresented at 36, fits-within the 'guideway -33 at the opposite sides of the wrist pin's from the member 35 and are formed :with V shaped portions 37 the V shaped portionsof the twoblocks extending toward each other, as shown-in Fig. 1. The

head member 32' ofthe connecting rod is 'clampnuts 42 whereby the key blocks may the head 32 and the other set'operating through the bottomof the head; as shown in Fig. 1. The key members '39 are apertured to receive clamp bolts 41 provided with so be moved toward each other and thus apply pressure to the members 36. By this means the brasses 3536 may be adjusted to control th position of the connecting rod 5 relative to the wrist'pins, and take up lost motion which may occur, and maintain the parts in adjusted position. Thebolts 41 are preferably provided with jam nuts 43 to prevent the clamp-nuts 42 from working loose.

By thisarrangement when reciprocal motion is imparted by-anysuitable means to the connecting-rod 31 rotarymotion will be imparted to the shell member 1213, and a universaladjustment between the. parts secured by simply manipulating the holding nuts 28 and 42;. The improved device maybe applied without structural change for driving wheels or devices of various sizes and forms and thus adapt the device to various forms of machinery and to machinery employed, for various purposes;

In Figs. 5 and 6 a modification of the construction is shown consisting in an attachment whereby power may be transmitted fromthe rim of themember 12 instead of fromthe -shaft' 10. Themodified attachment consists in providing the rim 13 with an annular, gear rack 48 and an inwardly directed fiange.49,-the latter bearing against the rear outer face of the member 12 and secured .thereto by set bolts or like'f'devices 47. The flahge49 is provided with inwardly directed projections 50,while the ,l remainder-of theflange extends outwardly of the bolts 23 and the nuts 24; so th at. the presence ofthe fiange and its projections do not interfere with the operation of the bolts whereby the members 15 are secured in position. a j
