. CAN-OPENER.

T0 all wlw/m t may concern: l

Be itknown that I, Ronnnr- H; Eimer, a citizen of the United States 'of America, re-` siding at Brighton, in the county oiIla-sh`4 ington and `State of lowa, fhave'inve'nted certain new and useful Improvements in Can-Openers, of which the following. is a specification, reference being had thereinto the accompanying drawing.

This invention relates to can openers and y hasfor its principal object the production of a simple and eflicient means whereby the can top may be removed by one stroke of the can opener. f y i yAnother object of this invention is the production of a can openerwhich is so con-l structed as to eiiiciently cut a kcan top fnom the can, while a plunger is employed for removing the can'top which may b e carried byv the canv opener.y 1 p A stillfurther object yof this invention is the production oi a can opener whichmayA be easily operated for allowing thefsame to be used for removing a can top without possibility of cutting or injuring the hands.

With these and other objects in-view this inventionconsists of certain novel combinations, constructions, and larrangements of parts as vwill be hereinafter fully described and claimed. j,

The eanopener em- 6 which are semi-cylindrical in shapeV while their straightupper edges 7 lit upon the body 1 adjacent the inner portions of the lianges 3. y These blades 6 taper, to pointed lower ends which constitute cutting' portions for the insertion of the blades 6 into the can body. Each blade 6 is further provided with a plurality of inwardlybent ears 9 which lit adjacent each other when the` two blades-are used in connection with the canopener, as-shown clearly in `Figs. .6 and?. The'retaining plate 10, as shown clearly in Fig. 5is number of

notches

1,1 within which theears 9 areadapted-to fit when the can opener is As the can opener is constructed only two of the-notches will be used at a time, although any number ot', notches may be provided. for allowing the lconvenient assembling ofthe can opener and for producing a lighter structure in connection with the openings 12 formed in the plate. A'hollow as shown in Figs.

neck 13 extends -fromthe centralportions 1 of the plate-1Q and passes through the opening- 5 formed in the body 1. When'the can opener is assembled it will be seenthat the blades `6.will be held* uponthe body 1 by meansv ofthe ears 9 ttingfwithin the notches 11 lformed in the plate 10. After the neck 13 has been passed through the opening 5 of so as to be flared at at 14, thereby holdingl the y plate against ment. A headed plunger 15 passes through the neel; 13 and carries the washer l16 upon its lower end.)k It will ,be seen that after the can .opener has been' assembled the blades 6 will be positively retainedupon the body 1 by fitting within the flange VSofthe body 1, while the depending ears 17 of the plate 10 will be directedpositively in alinement with the ears lips ljof'fthe-.body 1,- yas clearly shown in Fig. 2,- so as toprovide a broad bearing surT from wabbling orbecoming loose when in use As the plate will be positively retained upon thebody ylk by means of the neck 13 it will be seen :that the blades will also be re:

accidental displacel ace for preventing the blades tained in their correct positions since the ears 9 thereof will t within the notches 11 of the plate 10.

VVhen the can opener is in use the points S of the blades 6 are positioned upon the top of the can as indicated in dotted lines in Fig. l. The operator at this time is gripping the handles 2 very firmly so that upon a downward thrust of the can opener the points will pass through the top of the can, while the edges of the blades will cut the top. As the downward movement is continued the top of the can will be evenly c ut until it is nally removed from engagement with the can, since the two semi-cylindrical blades 6 will form a complete circle for efficiently removing the can top from the can. After the can is opened the can top will of course, be carried in the upper portions of the blades. Then by exerting a downward pressure upon the headed plunger 15 it will be seen that the can top will be very quickly and efficiently ejected from the interior of the blades. In order to open comparatively flat cans a number of thrusts may be necessary. Under such conditions it will be seen that the top of the can may be easily removed without the necessity of employing the headed plunger.

From the foregoing description it will be seen that a very simple and efficient can opener has been produced wherein after the assembling thereof it may be operated for positively removing can tops without danger of injuring the operators hands, while simple and efcient means is provided for removing the can tops from engagement with the device which removed the same.
