To all whom t may concern.'

Be it known that ll, HENRY-R. CORDUM, a citizen of the United States, and residin at Gillespie, county of Macoupin, State o illinois, have invented the new and useful vide a can perltorator which shall be capable of perforating the can Without external assistance, such as resting the can on the table to hold it steady, etc.

Another object of this invention is to provide a can perforator which shall be cheap and simple to manufacture.

Further objects will appear from the detail description taken in connection with the accompanying drawing, which illustrates a can pertorator` embodying this invention in which l designates the can to be perforated. 2 and 8 designate the jaws of the per- 'torntor These jaws may be `Inade ot punched sheet metal, each being provided with a pair of wings l adapted to be bent over to embrace the other jaw, as'shown in the drawing. This construction renders the jaws movable relatively to one another in a rectilinear path.

rlhe upper jaw .2 is' provided with a per' forating point 5 and the lower jaw-3 is provided with abutments 6 and 7 which are out of, alinement with one anotherand each of which is ada ted to` engage the bottom of a can, the di erent jaws bein used for different sized cans, as indicate in the 'drawing. Each jaw is provided with an ear 8 to which ears are pivoted a pair of levers 9 pivoted'at 10 to one another and provided withI manipulative handles 11. A ring 12 is attached vto the handles 11 and tends 4to separatethemso as to automatically open the jaws when the handles 1 1 are released.

ln operation the can l may be grasped in one hand and the performer, held In the lother hand, may be.applied to the can, the

bottom of the lcan being engaged with one of the abutments 6 or l7 and the topbrought under t'he'point 5. Pressure on .the handles 11 will thenmove thejaws simultaneously 1921. serial No. 479,656.

toward one another, thereby forcing the point 5 against the top of the can to perforate the same. lt will be noted that the construction is such that the jaws are moved toward each other in a rectilinear path and that the force exerted on the can acts substantially along one edge thereof, there being no tendency to ti the can or throw it out of alinement. This makes it possible to pertorate the can without the aid of any ex ternal assistance, such as resting the can on the table to hold it steady. With this device they can held in one hand may be si1nply and quickly perforated by means ot this perforator operated by the other hand.

lt is obvious that various changes may be made in details of construction without dcparting from the spirit of this invention; it is, therefore, to be understood that this invention is not to be limited to the specific let-ails shown and-described- Having thus described the invention, what is claimed is:

l. A can perforator, comprising, a pair of relatively movable jaws adapted to engage the top and bottom of a can, and operating;r elements connected `with and I''or simultaneously moving" said jaws to pertorate the can.

2. A-canperforator, comprising', a pair o' jaws adapted for relative-rectilinear movement and adapted to engage the top and bottom of a can, and operating elements counec-ted with and tor moving said jaws to pertorate the can.

3. Acan perforator,con'iprising; a pair of jaws slidably mounted each upon the other tor relative 'rectilinear movement, and ma nipulative elements on said jaws for moving the same to perforate the can.

f1. A can pertorator` comprising, a pair ot jaws adapted for relative rectilinear movement, and a pair of operating levers pivoted to said jaws and to each other adapted to move said jaws to perforate the can.

5. A can perforator, comprising, a pair of jaws adapted for relative rectilinear movement, a pair of operating levers pivoted to said jaws and to each other adapted toI move said jaws to' perforate the can, and means for automatically separating said jaws.V

6. A can perforator, comprising, a pair of jaws mounted for relative rectilinear movement, a perforating element on one of said jaws, a plurality of abutments on the other oi said jaws, said abutments facing in the dsame direction being out of alinement with relatively movable jaws adapted. to enga-ge the top and bottoni of a can, oneof said jaws having` an'abutment and the other a pei'- .l'orator, and operating elements connected i5 with said jaws adapted for positioning said abutment and said perforator to el'igage the can and for moving' said jaws to pei'foi'ate the.

In testimony whereof ll aflix my signa- 20 ture. this 20th dav of June, 1921.

HENRY R. CORDUM.
