CAN-OPENING DEVCE.

Application filed June 19, 1922. Serial No. 569,416.

To all whom t may concern.:

Be it known that l, FRANK B. ANGELI., a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Can-Opening Devices, of which the following is a specification.

rhis invention relates to improvements in l0 can openers7 the principal object of which is to produce a can opener which will operate upon the side of a can in counter-distinction to the usual can opener which operated' upon the top or end of the can,

Another. object is to provide a can opener wherein the can being operated upon will be retained against turning.

A. further objectY is to provide means whereby the cutter lever will be centrally held with respect to the ve tical axis of the can. f

Still further objects are to provide simple means for gripping the can, simple means for effecting the adjustment for any size of can and simple means for retainingr the cutter in adjusted position with respectY to the can.

Other objects and advantages will be apparent during the course of the following f1@ description.

In the accompanying drawings forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same,

- Figure 1 is a top plan view of my improved opener shown applied to a can,

Figure 2 is a cross-section taken on the line 2 2 of Figure 1 looking inthe direction ofthe arrow,

Figure 3 is a vertical section taken on the line 3 8 'of Figure 1 loolringin the direction of the arrow, A v

liigure 4f is a vertical section taken on the line 4-4 of Figure 1. looking inthe. direction of the arrow,` and Figure 5 is a fragmentary det-ail view of thelocking dog viewed from beneath the opener.

There V are many commodities upon the market that cannot. be removed from the can which is open on the end. that is by having a hole cut in one end. -The reason is that the restricted size of the hole is not sufficient. to provide for the sizeof the contents. This is true in emptying canned meats and tamales from the can. An attempt vhas been made to provide a side seam which can be torn with a key, but this has proven unsatisfactory` owing to the tin out of which the can is made tearing. I Y i l therefore provid'ea can opener which has a cutting knife which knife is adapted to penetrate the can and pass around the entire circumference of the can thereby severing one end of the can which'will allow the entire contents to be removed without breaking or disiiguring. y Y Y In the accompanying drawings wherein for the purpose of illustration is shown a. preferred embodiment of my invention. the numeral 6 represents the top of an ordinary camand the numeral 7 the side wall ofthe same. rlhis can is of the usual construction and' needs no further description.

By now referring to Figure 1, it will be noted that the numeral 8 represents a bar AND ONE-EIGHTE provided midway of its Vlength with teeth 9 i,

and having at one end a V shaped member 11 which is equipped at its extremities with serrations 12 which are adapted to contact the side of the can at a point adjacent the end. rl`his V shaped' member is also provided with lugs'lf which are adapted to contact the end ofthe can as is shown in this figure. rlhe member 11 is preferably secured to the bar 8 by rivets 111. vbut it is ob.- vious that any means of connection might *be used. rihe opposite end of the bar 8 is provided with an offset portion 16. which offset portion engages portionof' a bar 17. The

part of the bar 17 adjacent this engagement is dovetailed' asis best yshownfin VFigure t in g order that the offset portion 16 may slidably engage the bar 17. This har is provided with a handle 18 at .one end and'at its opposite extremity with an offset portionV 19 similar in construction tothe offset portion V16 of the bar 8. This offset portion19 engages the bar 8 asl shown in Figure 3 and is also dovetailed to form a sliding engagement. At 2 1 and at 22 l have providedratchetteeth, which ratchet teeth are .adapted to VbeV contacted by afdog 23. rlhis dog is riveted or otherwise secured to a link24, V'pivoted as at 26 to the bar 8 and-provided withan operating knob 27. 'A handle 28 is pivoted to the bar 17 as shown at 29n The opposite extrem- I have shown teeth .formed on the bar 17,

ity of this pivoted handle is arcuate and rries serrations 81, the purpose of which is to engage the side of the can in a. manner similar to the serrations 12 when the handle 28 is moved in the direction of the arrow A of Figure 1. l

By now referring to Figure-s 1 and 2, it will be lnoted that a pinion 32 is positioned between the bars 8 and 17 in sucha manner that its teeth engage the teeth 9 and 21 so that as the bars 8 and 17 lare moved lengt tudinally relative to each other the pinion will roll therebetween.A A -bolt 33 passes through the center of the pinion 32 and has pivoted upon its upper extremity a lever 34 ,offset as atr 36 and terminating in a handle 37. A slider'38- is adapted toengage the teeth 41 formed upon the lever 34. This slider v8,8 carriesa knife 42 upon its under' surface, whichA knife is vof the ordinary construction'. Thenumeral 18 designates a'washerwhich is secured t0 the lower end of the bolt ywhich washer prevents the withdrawal of the pinion from its position between the bars 8 and 17.

The operation of vmy device is as vfollows The device as a whole is placed over the can so that the lugs'l rest upon the top of the can, which' brings theserrated portions of the V shaped member 11 into Contact with the side ofthe can. The knob 27 is then pressed withthe thumb so as to disengage the dog 23 from the :ratchet 22 after which rthe barsu 8 and` y17A may be moved longitudinally relative to each other until the serrations 31`on the end of the handle 28 engage vthe oppositeside of the canas best shown in Figure'l, after which the handles 18 and 28 are grasped in one hand so as to tendnto move them together thus firmly gripping the can top. The slider 88 is then moved toward the can so that the knife 4t2 will Contact the can.l |The handles 18 and y28 are then contracted so that the cutter 42 will pier/ce vthe side of the can as best Shown in Figure 2.L The tooth 89 on the slider will then Vautomatically engage the teeth41 as the handle 37v is moved in the direction of the arrow B. After a partial cut has been'made, the handles 28 and 18 are released and the can` is partlyrotated afterfwhich another cutis made. In this manner it is possible to cut around the entire top of thetany and sever the same without in any way. lmutilatingthel contents.

As before 'mentionech I have provided means whereby the bolt 33 will always be positioned above the'center of thel can durinl1`the cutting action.

It is to beunderstood thatthe formof myfiventea herewith Shown and dscrlvelV is t0 be taken as' a preferred example 0f .the Seine;aadjthatvarieus,chansesia fileshare,

size and arrangement of paris may be resorted to without departing from the spirit of the invention or the scope 0f the subjoined claims.

Having thus described my invention, I

o claim 1. A device of the character described comprising spaced parallel bars, gripping means connected to said bars and adapted to engage the side wall of a can, a lever longitudinally movable between said bars, i" and a cut-ting element slidable on said lever and adapted to be rotated about lthe side wall of a can, substantially as and for the purpose described.

bar and having one of its faces serrated at pre-determined point-s throughoutits length, means for temporarily locking said bars one to the other, a pivoted lever secured on said second mentioned bar and adapted to co- 'operate with said V shaped member for engaging' the can, a pivoted cutting lever supported between said bars, and a cutting' element'slidably mounted on said pivoted cutting` lever, for the purpose specified.

4. In a can opener, a V shaped member adapted to engage one side of a can, a pivoted lever, one end of which is adapted to contact the opposite side of` a can from said V shaped member,` abar secured to said t shaped member, a bar secured to said pivoted lever, means for maintaining a sliding engagement with said bars, means for temporarily locking said bars against 'movement in one direction, apinionpositioned between said bars and having` roll-Y ing engagement with the opposing,TA faces` of said bars, a lever pivoted on said pinion, teeth formed on said lever, a slider movable longitudinally on said lever, a tooth formed on said slider, said tooth being adaptedito engage said teeth on said leverv` and a cutter mounted below said slider and adapted to engage the side of a can atr a?, point Slightly below its top.
