The rivet 19 also extends through apertures provided therefor. in parts 5 and and is riveted, or lattended, at the end thereof against the under side or face of part'y 5, as atI 20, Fig. 1. Theportion bf .rivet19 which extends through the apertures i'n parts 5 and .6, is preferably, of less diameter than 6 respectively, fitting tightly in said apertures; 7

34 is then forced into Hange 26, at one end. 27 represents a wheel whlch. is provided with ratchet teeth 28. Roller'25 and wheel 27 are, respectively provided with a screw threaded central aperture, said screw threads tting closely to corresponding screw threads on shaft 22; and said roller and wheel are rigidly mounted on said shaft 22 by means of the co-acting screw threads, and the riveting of the end of said shaft against the face of wheel 27, as at 29, Fig. 4.

envertical shaft 2,2, with roller 25 and 27, rigidly mounted thereon as reare rotatably mounted in frame 1, the roller is rotatable in the aperture provided and said roller also fits loosely in slot or recess 15, at the end of member 14 of part 6 of the movable frame. represents a bolt which is rigidly. secured in member 14 of part 6'of the movable frame, as by screw threads on said bolt fitting an laperture having corresponding threads in Ymember 14, and by the nut 31. 32 is a. roller, and 33 a cutter, which are mounted on'bolt 30. 34 represents a lever which is manually turnable on bolt or rivet wheel 35. Said bolt or rivet 35 is rigidly mounted Y on Vframe 1, and 4forms the fulcrum of said 36, 37, represent cams, or cam surfaces, on one end of lever 34, and are illustrated as integral with said lever. Cam 36 is--al'ranged to abut or come in contact with member 1Q of of the device, abut or come part 5 of the movable frame and cam 37 is arranged to in 'contact with the end 38 of part 6 of said movable frame, which is adjacentthereto. The position of the slidframe comprising parts 5 and 6, on frame 1, is controlled by lever 34 and cams 36, 37; one of said cams moving said-sliding frame in one direction and the other in the opposite direction, as lever 34 is turned on its fulcrum in one or the other direction.

39, Fig. 1, represents a portion of one end of a cam-and 40a portion of a wall of a can. 41 represents the ordinary peripheral liange on the end of a can, and 42 the fold of the wall 40 on to said ange.

To operate .the device the lever 34 is turned on its fulcrum into substantially the position illustrated inFig. 3, thereby separatin wheel 27 from roller 32 andcutter 33. The device ,is then' laced on a `can substantially as illustrate in Fig. 1, and handle substantially the position illustrated in Fi 2.v The peripheral edge of cutter 33 is thewvall 40 of4 the forced against said of wheel 27 are can; the roller 32 is wall; and the teeth 28 forced against fold 42.

- Handle 23 is then turned clockwise, vas

viewed in Fig. 2, and by said turning the teeth 28 will turn the can and the peripheral cutting edge of cutter 33, will continuously cut the wall 40. The turning of handle 23 thereby forced through is preferably continued until said cutter has cut said wall entirely around the can and bottom 39 thereby separated from wall 40.

If the can is rectangular in cross section, with rounded corners, the device is placed thereon in the manner last above recited, and as illustrated in Fig. 1; and handle 23 is turned on its fulcrum as above set out. The ratchet teeth 28 of wheel 27 will thereupon engage with fold 42, and move the can along to a corner, and will then turn the can and moveit along the next corner of the can; and upon continuous turning of said handle 23 will turn the can around and separate the bottom ofthe can from the walls thereof.

` During the operation of the machine as above described the member 9 of part 5 of the movable frame forms a guard protecting the operator from the cutting Wheel 33. e claim:
