'-To all whom it may comm:

Be it known that I, GroizenGgWnsnR,"

of Illinois, have invented certain newand' useful Improvements in Box-Opening. -Devices, of which the ,following is a specification.

. This invention relates to box or can opening devices, whichare adapted to facilitate the looseiiing or removal of the cover from a can or box of the eneral style employed in the packing of blac ing, stove polish, paint, bakmg .p'owder, and similar commodities.

'Qans- 'otthi's'character ordinarily are pros or covers which slip down preserve the contents of Y 'esfsary be a tight one, wit is frequently experien remove thecapor cov I v The object of the present invention is to so construct the canopening devices that they may be ap lied to a cap, or cover of the st le mentioned -*=-=w 'thout p ercing the wall '0 the cap or cover, which might result in damage to the contents of the can.

Another object of the invention is to so se- 1 1 re the key lever tothe cover that it may 1 and having the o invention applie i be left off-to facilitate packing andshi ment of the boizes. or cans-and may therea er be furnished to the consumer.

The lip co-acts with a key lever 17, comprising a handle portion18 and'a rounded cam. end 19. The handle portion is provided at its outer end with a finger piece 20, which is bent out from the under edge at right an: gles thereto. The key lever is further provided,-' near its cam end 19, with an out wardly projecting pivot stud 20*, which is preferablyj in the form of a tubular bur struck .out from; the bodyof the metal by a uric-hing operation. The upper edge of the iiey leyer is cut and struck outwardly to furn'ish 'a spring tongue 21-, which :is'adapted 'to bear'agai'nst and co-act' with the outer osition.
