Application filed May 81, 1910. Serial Nor-328.

To all whom it may concern:

Be it known that I, NEn H. MoPEAK, a

citizen of the United States, residing at Cornerstone, in the county of Jefferson and State of Arkansas, have invented certain new and useful Improvements in Can-Openers, of which the following is a specification.

My invention relates to improvements in can openers, and it consists in the constructions, combinations and arrangements herein described and claimed.

An object of my invention is to provide an improved can opener especially adapted 'for sardine cans, which Will cut a flap, or tongue, comprising approximately the entire top of the can and automatically elevate the cut flap.

A further object of my invention is to provide\an improved can opener'avhich cuts the can progressively along the sides and free end of a substantially U-shaped flap, and firmly supports the free endof such flap during the severance thereof; thereby avoiding the annoyance caused in'previous constructions by buckling of the can and depression of the cut portion.

A further object of my invention is to provide an improved can opener constructed to operate with great rapidity and convenience, with entire safety to the operator and without danger of injury to the contents of the can. I

In the accompanying drawings, forming a part. of this application and in which similar reference symbols indicate corresponding parts in the several views: Figure 1 is a perspective view, illustrating one embodiment of my invention in open position after cutting and elevating the flap of a sardine can, and Fig. 2 is a central longitudinal section, showing my invention in partly closed position with the serrated cutter just beginning to cut the sides of a flap in the can top.

Referring to the drawings, 1 indicates a base provided with a recess 2 for receiving a sardine can 3, and having a clamp 4 for overlapping the front end of a can placed in the recess. The recess'2 can be formed of sufficient size to receive all required different sizes of cans; the can being always po sitioned with its front end beneath the clamp 4.

A swinging member 5 is hinged at 6 to the rear of the base 1, and carries a cutter 7 provided with a serrated cutting edge 8 for preferably formed of a continuous metal.

.band detachably secured to the. member 5,

the can at successive points along the outline of the flap, and cut with a'shearing action,

in both directions from said points; thereby minimizing the cutting pressure on the can, and avoiding all danger of distorting the can and injuring itsjcontents.

An elevator 12 project's-from thgilswlng- 1 ing member 5 beyond the adiaoenttidge of the cutter 7, in position-for pieFgipg-the free, endof the can flap'be'fore complete severance of the latter -by--' 'such adjacent cutter edge; said elevatorv being "provided with a shoulder,- or.head,'-;f or 'hookinglbe neath the flap to elevate latter upon up-l a pened tofacilitate piercing 'of the can flap,. and extends'substantially the plane of the adjacent cutting edge 8, in order Qto'cut to Ward swing ofthe membfeffi.

The lower face of the elevator-1s the margin of the flap arid thereby permit ready displacement of the elevator from said flap during upward swing-of the member 5.

I have illustrated and describeda 'preferred and satisfactory construction, but 55 1 changes, could be made within the spirit and scope of my invention. The puncturing hook in the line; of the cutter is forced through the cover when the cutter is depressed and vided with cutter members arranged to sever the cover of a, can, and a ipg qet point upon said-swmgmg mem :space being'disposedwvith- 7 us esc'ribed my invention,.what
