.Y i CAN OPENER Filed March 13. 1931 v INVENTOR Patented Nov; 2 4, 1931 UNITED I STATES: Y or` Application filed March 17,3,

The object of this invention is to provide a can opening device of the type v disclosed in my'U. S. Patent No. 1,742,140, the' present construction involving certain important im provements with reference to construction, assembly and operation, and showing hori- Zontal mounting. f

With the foregoing and other objectsy in view, the `invention consists in the novel features of construction and in Vthe novelarrangement of the elements herein disclosed', it being understood that' modifcations,l alter ationsor changes may be made within the scope of the claims Without departingjfrom the spirit of the invention.` In the drawings forming .part ofthis lapplicationr-` f. f

Figure 1 shows thedevice in elevation, a bracket for mounting the appliance on a stationary element appearing at, the left of 'eled edge at 28and` this cutter is formed by deiecting a portion of thepressure plate 29` n the view. Y

Figure 2 1s a view 1n elevation, the view being from kanother angle, 4as compared Figure 3 constitutes a section online 3;-,3 ofFigure 1 j A main supporting element comprises a `frame 10 which may be reinforced by alongitudinal rib 11, the plate or strip of material being formed by dies or the like, and said platel 10 having a laterally deflected end portion 12 adapted to cooperate with an angle element 13 secured by means of rivets or the like A14C to themain plate.

In order to support the structurejust re.

ferred to and the operative elements, on'V a stationary device, I provide a bracket comprising Va plateV 15 havingears, such as 16, struck up therefrom, and these earsmay be spaced, so that the upper pair, considered in Figures 1 and 3, will` be farther apart than 7 the lower pair. The portions l2 and `l3`wll,

therefore, have inclined edges, so that the complete end portion of the tool-supporting device Will represent a tapered foot or end member, as will be observed in Figure 3.

Plate 10 is provided with a cam slot 18 having aV forward portion 19, and a portion 19 toward the opposite end, or the inner end of the opening. lug is providedby cutting camajseeure'cl tofitheferank arm bynlea a screwortheli'kez2ti :'Altoothedrwhe'eEQr.

4A guiding element or'bracket includes a portion 34, deflected laterally at 35 and 3 6, z

and these portions are apertured for the accornmodation of the bolt 30. The bracket thus described is retained by means of rivets or other securing devices 36. t f

The operation is similar to thatfdisclosed in connection with my previous patent, re ferred to by number, but thejspecial mount- V ing of some of the elements, including the cut-` i V't'er, the crank ar1nan'd the rotatable means,

is important. rI lhebead orannular flange at the end of the Canis engaged by the toothed Wheel 25,and upon-the rotation of the crank arm 21 'tow-ard the rightin-Figure 1, thehub portion 25rdesupwardly in the cam slot,
