H. v. UNDERWOOD CAN TURNING, MECHANISM Filed Aug. 30. 1922', 2 Sheets-Sheet 1 1 ,4 o o o a a 20 Attorneys guide for' moving this end 34 from ajpoint above the Wheelto a point below it and When the end 34c is resting on pinion" 3O meslibetween' the studs 37, caus ing the Wheel to be rotated in one -(l1I8Ctl0I1 VJhenthe end 34 is located b low the Wheel and held up by th-ebottomof the slot 32' in the bracket 33, the teeth on the Wheel or i upini'on K atthe top thereof, similarly mesh 'betiveenthe. studs 37 and cause the Wheel 3 ';to;rotate in-the other direction.

' Onthel bottom of the Wl168l35 is a bevel gear 242 meshing. with a bevel pinion 43 on 'a shaft-t l. This shafthas a-seriesof bevel pinions 4'5 meshing with bevel'gears 46 on vertical shafts parallel to theeshalft" 36 and spaced therefrom. On the top of each ofthefshafts36and 47 there is a plat-e 4c8.

The operation ofthe deviceis very simple.

rection and transmits its motionof-rotationthrough thegear 28 tOtllGSlliLfi; 29 constantly. This shaft by its constant rotationin onedirection With the. end 34 resting on the top of the 'WllBGl for example-rotates 'thatwheel around 'through less than a com- *p lete revolution. This maybe half a revolution orsconsiderably more, i In the presentgcase it. is shown as about five-sixths of a revolution'. I When the Wheel has/rotated, far

enough for the end 34 to come into contact :withone. of the surfaces 4'0 that end will be .forced down'through the space between the. fiilrfacs- LO and41 so as to come below the. v;*heel-35. But thewheel or pinionBO continues in mesh With the end stud:3 7 and,

being-held against further descent by the delayiit starts the Wheel 35 turning in the opposite direction. It'will. continue to turn in that Way until the opposite surface 40 geomes into contact with the end'34.v This 'williraise thislend up. to a point above the P Wheel 35 and immediately reverse the r0ta-' tion ofthe wheel. The turning of theend up *or down-through the semi-circular space between the surfaces aOand 41 is a .positive motion caused by these guiding surtacesand, bythe-p'ositive rotation of the V 51 wheel '30} around the .endistud 37.

t. A ll'the' cans in' the series'are rotated. in

enactly the same way by means ofone of.

This-prevents its being sub]ected to a continu'oustwist all t the 'tline. in; one direction and eliminates all tendency to kink up in the canand occainvention rection and then automatically reverse them 'but' one "convolution is drawn up from the can coming outin one direction and then H the next coming out in the opposite direc tion; These are equal and 'oppositeand all kinks and twists are neutralizedso thatthey arejnot passed on to the next machine which .is to operate upon the material. 7
