v CHARLES AA ON'D A RRAH or enem rows; I l

Be it known thatI, CHARLES A. 1DA RA' acitizen of the United "States,residing at Ottumwa, in the county of VVapellofand State of Iowa,'have invented bertain new and useful Improvements inCan-Openers; I and I do vdeclarethe following to be a full, I clear, and eXact description of .theinven tion, such as will enable others, 'skilled' in the art to which itj 'a'ppertainslto make and use thesame. I I

My invention'whi'ch' relates to improvenients'in can openers, has for its principal object to" providea device ofthis character view, the invention resides in the novel feaproved can opener'show'ing the s'ainein use;

tures of construction and unique combinations, of parts to bei'hereinafter fully described and claimed, the descriptive matter being supplemented by the accompanying "drawings which constitute a partof this application and in which? I II I Figure 1 is a side elevation of, the m- Fig.2 is a front. elevation of Fig. '1; I I

Figs. 3 and 'are horizontal sections on Fig. 5 is a detail vertical sectionon the plane of the line 5-5 of Fig. 3;

Fig. 6 is a horizontal section on the plane indicated by the line 66 of Fig. 1;

Fig. 7 is a perspective view of the verti cally adjustable bracket carrying the can opening means; and I I Fig. 8 is a similar view of one of the links for operating the can clamping jaws.

In the drawings above briefly described,

' the numeral 1 designates a vertical standard having laterally extending feet 2 at its upper and lower ends secured to a verticalwall or the like 3, said standard being by preference stamped from sheet metal as shown. A

the'p'lanes of the lines 3'3 and f eta "51551134 is fsflppeiteja J n -idly byithe standard .1, near' litsfjlower end, whereas a bracket 5 isirnounted slidably o n said standard above the 'clamp carr esa-canopening'Ib lade G and means for goperating the same. 1

ca'n, supporting plate 7 rigidly secured and braced at 8 .to the standard. 1 and, having plurality of slots 9. disposed; substantially I in a tangential manner", although Y said slots will in most ca'seslbe arcuate as shown. triangular lever '10is disposedbeneath plate 'Z and is pivoted at its' 'cejnter to the centerof saidplate assh'own at ll, said lever 10havg t fingfa handle la'wher'by it maybe turned around its .pivot. Wire links 13 are bent downwardly at; one end at. 1a and upset. in

openings in. the three} corners ofthe-lever bent upwardly 15 through the, slots 9, said links being pivoted, by. means ofsaid .upw'ardlyibent ends, to flat preferably sheet metal jaws 1 6 whi' ch rest on the plate 7.

10, whereas thelotherflends of said-links are Bythisl construction, itl will; be observed that swinging of the handle 12 in one direction, will so movethelinks.13'asto cause the ".jaws 16 totravel inwardly abovethe slots 9, whereas operation ,of said handle in the ,wardly. It will thus, be. seen that cans. of

'85 other"dir'ection will move said j'aws out' various sizes may; be, clamped in the plate T the cipeningfmeans is being actuated, 1t belng' understood that the operator must hold the handle, 12 operative position.

while .the' opening process is being carried out." I

The m k s 5 isfpi'rmbi am am I horizontally elongated sheet. metal plates 17 secured together by rivets. or the like 18, one

end of each; plate beingi bentilaterally out ward fattld for with the front side of the'standard'h'then rearwardly at 20 for engagement with-the edge of said standard,

and finally inward at 21 to form a flange I "contacting'with the rear side of the standi ard. "The formations 19. 20 and 21 of'the two plates 17 constitute a slide which per- I mits the bracket 5 to move vertically accord: ing to the height of the can to be opened.

The ends of the plates 17 remote from' those just described, are bulged outwardly at 22 to form a bearing for a vertical shaft 23,

said shaft having on its lower end a prong 24 to penetrate the center of the can top,

while secured to said shaft directly above the prong is a laterally extending arm '25 upon which a slide 26 is mounted said slide carrying the blade v6 above described. A gear 27 is carried by'the upper end of shaft 23 and meshes with a gear segment 28 ntthe lower end of a vertical lever 29 which is fuL crumedat 30 to an inclined arm 31 which rises from and is formed integrally with the upper edge of one of the plates 17, said arm being ofl set from the plane of said plates as shown most clearly in Fig. 7. By the construction just described, it is obvious that after clamping the can between the several Ijaws 16,"'th'e bracket 5 maybe lowered so that then 9; 24mm Mil-C166 both penetrate the top of can, said blade being positioned adjacent the edge of said top} This having been done, the lever 29' is so operated as to cause sa emes and gear 27- to rotate the shaft 23,thus swinging the arm 25011 a circular path and s'ii nilarly moving the .blade'tof completelycut the top ofthe can from the bodyfthereof. i

om ef s i g, tak n in conn ction with the accompanying drawings, it will be observed that I ha'veprovided' a can opener which will be highly eflicie'nt'and durable,

yet "one which may be easily and inexpenr without sacrificing the principal advantages.

I claim 1. A' can opener comprising a vertical standard, a'clam'p carried by the. lowerend I thereofifor gripping the lowe end of a can, a bracket slidable vertically on said standard and consisting of a pair of hori zontally elongated metal plates standing. on

' edge, and secured together, one end of said plates being bent laterally outward for con,- tact with *the front side of the standard, then rearwardly for engagement with'the edges thereof, and then inwardly for. contact with the rear side of said standarchthe Copies of this patent may be. obtained for five cents each, by Washington, D, 0.

other ends ofsaid plates'being bulged outwardly to form a vertical bearing, an uprie shafit i qeabiyim in said in'gand having a prong on its lower end to penetrate the center of the can top, a laterally extending arm on said shaft above said -iprong, a can opening blade slidahle along sald arm, a pinion secured on the upper end of said shaft, an operating gear meshing with said segment, and an arm rising from and formed integrally with the upper edge 'ofbneqf said plates and serving as asupport for said gear.

2. A can opener comprising a vertical standard, can opening. means including a slide mounted on the upper portion of said standard, and a can clamp. consisting of a horizontal plate rigidly'secured tofand projcc illg forwardly fromith e lower end of said standard, said plate having a'plurality of slots disppsed substantiallylon tangential lines, can gripping jaws. resting on said plate and extending across said slots, ahoricn al y w n ia rm atins l v r belo lsaidplateand fulcriuned to the center theref i -e i si eeee ins a le a w and having verticalportionspassing slidably thr h s d 19s.

3;. A can opener comprising vertical ta rd, an opening means havin a l d mount d n the upper n ti n cf said stand ard, can clamp consisting of: ahorizo ital metal plate extending forwardly fron j the lb iver end of said standard and rigi-dly'secured thereto, said platefhaving a plurality of slots disposed substantially ontangential lines, a lever fulcrumedzto, the center of said plate, and located belowthe latter, horizontal wire links below said plate and having on e'ndbeiit upwardly through theslots thereot, the other ends of said linlis lbeing. bent downwardly through openings in saidlever, and an p i i w est ie' 011 a la and mountedon said upwardly bent ends of the links.
