UNITED STATES PATENTIOFFIDIOE.

a I OAR-OPENER.

Be it known that I Eow'ann A. Conn, a citizen of the United States, residing at tain new and useful Improvement in Can- Openers, of which the following is aspecification.

My invention relates, to a new and useful improvement in can openers, and has for its ob set to rovide'an exceedingly simple and e active dbvice of this character, whereby a can may he perforated, the device bem principally designed for use upon cans hol 111g evaporated milk, in which it is only.

necessary to make two ,small 'op'enin s, one for the admission of a1r,-the other or the outlet of the contents.

Another object of the invention isto provide a can opener which may be readily and quickly adjusted to fit upon different sized cans, and further to provlde means whereby .the device will adjust itself to the varying sizes of cans supposed to be of the same diameter.

Another object of the'invention is to pro vide a can opener having a bifurcated end, from the arms of which are formed grippinghoo rs adapted to en age the flange u on the top of the can, there preventing t e accidental withdrawal of t e can opener.

A still further object of the invention is a o 1produce a can openerof few parts, which.

wi be inexpensive in the cost of manufacture, yet strong and durable, and one in which-the parts may be readily and quickly assembled. a v

With these ends in view, this invention consists in the details of construction and combination of elements hereinafter set forthand then specifically designated by the claims.

. showing In order an those skilled inithe'art to which'this invention a pertains may understand how to make an use the same, I will describe its construction-in detail, referring by letter to the accompanyingdrawing forming a part of this'specification, in wh1chigure 1 is a perspective viewof a can opener made in accordance with mimprovement; Fig. 2, an ed e view t ereof it used u on a can, said can being shown in dotted: ines. Fig. 3, a bottom plan view thereof, and' Fig. 4, a section at- .the line w--w of Fig. 2 looking in .the direcof Allegheny and ennsylvania, ave inventeda oer With the carriage F is formed the p v catcd therefrom.

part of the handle t e In carrying out my invention as here embodied, A represents the handle or body ofthe can opener, having a lateral slot 13 formed therein, and having one end bifurcated to form the arms C, said arms bein curved outwardlyand forming an angle with the lower face of the handle, the outer ends of these arms having gripping hooks'l) projecting therefrom whlch en age the flange of the to a of ,thecan E, s% lines in Big. 2.

In the slot 13 is mounted the slidingcarria e F, having a fiangeG upon both sides wh1cl1 overlap the side wallsof the slot an rest upon the under face of the handle A. unch H, and in proximity to said punch an also own in dotted Patented Feb. 14,1911.

formed with the carriage is a ressure foot I, the front face J being'slight y curved so that the pressure is gradually brought to bear u on the side of t e can.

" Tot e to of the carria e is secured the handle upon bot-insides of-the slot B. A.v

portion ofsaidspring bulges upward, its free end engaging the sto s M, said stops being formed integral wit the handle; an having a Nportion thereof beveled, as ind .y to allow the, spring'to f'reelysli e so I In practice it is onl necessary to per- 3 forate a can in two "p aces'when the contents of said can are in the form of a liquid, such as evaporatedmil With the herein described can opener t-h 'e erforations may be readily and quickly ma e by placing the hooks D up'onone side of the can so that they enga e theflange upon the to. of the can, then ypre'ssin -.downupon t c outer (pr7ssure foot I will engage the o posite s1 e of the can, thus drawing the coke D into the side of the can, insuring-a grip, and by further pressure upon the handle the ,punch' H will perforate the top. t

The sprin K allows the pressure foot to adjust itsel to' varying diameters of cans supposed to be the same size, thus causing the punch H' to always entelfthe top the same distance from the edge of the can. 'llhe jacent said punch, and means mounte upon the carriage adapted to engage the stops for holding the carriage in various adjustments. 1

engagement of this spring with the different stops M ermits the device to be used upon cans of ifler'ent size.

Of course I do not wish to behmited to the exact details of construction here'showni as these may be varied within the limits 0 the appended claims without departingfrom the spirit of my invention.

2. A can opener consisting of a handle provided with a IateraL'sIot and having one end bifurcated to form arms, hooks projecting from the ends of said arms, stops mounted uon the handle, one side of each of said stops ein beveled, a carriage mounted in the slot, sa1d carriage having a flange formed vupon each side thereof overlapping the sidewalls of the slot and englgingthe under face of the handle, a punch formed sem s having a curved face formed integral with said carriage, and a flat spring mounted u on the carriage, its free end engaging the s ops.

3. A can opener consisting of-a handle provided with u lateralslot and having one end bifurcated to form arms, hooks projecting from the ends of said arms, stops mounted uponthe handle, one side of each of saidstops being. beveled, a carriage mounted in the slot, said carria e having a flange formed 'upon each side ereof overlapping the side walls of the slot and engaging the under'face of the handle, a punch formed integral with said carria e, a ressure foot having a curved face forme integral with said carriage, a flat spring, rivets for securin "saidsprin% to the car-.- riage, a portion 0 said spring eing. bulged upward, its free end engaging the stops, acting as an adjusting device, and a tenslon e pressure foot.
