A further object is to provide apower can opener which is adaptable to the various sizes of cans. v
A further object is to provide a power can opener which is simple in construction and economical 1n manufacture.

In large restaurants and hotels much'time and energy is lost in openingwith'a small hand can opener the great amount of canned 5e food used. My device solves these various problems:
I have used the numerallO todesignate the base portion of the housing. The back end of this housing "extends upward intofa trough portion 11, whilethe front portion of the "base is enclosed by the hover 412 a'I-id Fig. 3 is a top plan sectional view taken the raised portion'lii hinged thereto by the hinge13. The numeral 14 designates a cover ove'r the remaining portion of the base housmg 10. Mounted in the housing and below the cover 14 is'the electric" motor 16 having the form gear 17 on its drive shaft. J ourn-aled in the bearing'members 18 and 19 is the shaft 20 having loosely mounted thereon the worm gear 21 in engagement with the worm gear 17.. The numeral 22 is a clutch member slid'ablyunounted on and keyed to the shaft 20 andso positioned thatits teeth Wlll engage the ratchetiteeth 23 on the hub, of the gear 21 when in operativeengagement. V The numeral 24 ,is a spring for yiel'dingly' holding the teeth in engagement. Per-ma k l nently secured to the shaft 20' is thebevel gear: 25 which is in engagement vwith the bevel gear 26 permanently secured to the shaft -27'rota'tably mounted in the bearing member 28; Positioned within the opening 29 in the cover portion 12' and on the shaft 27* is the circular platform 30. The numerals 31. 32 and 33 are rollers which engagethe marginal edge of the platform and act as a bearing therefor. In this platform are three radially extending slot 34. In each of these slots are two screws 35 and 36 which pass,
through a bar 37 on the under side of the platform and screw into a jaw 38 loosely resting on the top of the platform. The numeral 39 designates a washer on each of the screws and inthe slot 34 which hold the bars and jaws the proper distance apart so that the same may slide in their respective slot. Pivotally secured near their centers to the collar 40 secured to the shaft 27 are the three arms 41. The numeral 42 designates a link pivotally secured at one end to each of the arms '41 and pivotally secured to a lug on'each of the bars respectively. Loosely mounted on the shaft 27 and just below the free ends of the arms 41 is the cone member 43. Secured to the sides and within the trough member 11 are two upright beams 44 a1id45 having the grooves 46 and 47 into which slides the member 48. J ournaled in but not slid'ably mounted in the bracket 49 secured 'to'the beam .45 is the rod 50' having one end threaded into the member 48 and the other end extending through the top of the' trough and onto which is secured the v crank handlehl. 'Pi'votally secured near one end to the member 48 is the lever 52 having oneend e'xtendin'gove'r the platform 30 and through-"the-forked member 53 secured to the the clutch fork 6S.
If it is desired to get to the working parts, raise the handle out of the forked member 53 and swing the cover 12 back on the hinge 13.
It will readily be seen that my invention'is automatic. All that is necessary is to place the can to be cut on the platform and pull down the lever. All machinery will stop as soon as it has been properly cut. 7
Some changes maybe made in construction and arrangement of my improved power can opener without departing'from the real spirit and purpose ofmy invention and it is my intention to cover by my claims any modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope.
I claim:
1.
