. CAN'OPENER. APPLICATION mzp MAY 11. 1921.

Y can OPENER.

ing is. a full, clear, and exact specification-1 My invention relatestocan openers-and refers particularly to'can openers capable F of producing openings having smooth edges at the outer periphery of a can-top.

- It is frequently desirable, to make openings in a can top which will allow theready and complete removalof the contents by.

flowing the contents therethrough.

It is likewise frequently desirable to open a can by the partial, or complete removal of the top from'the sides thereof with the edges at theline of i ing device F igures' l and 5.-

formation of smooth separation. I

The device of my invention accomplishes these,.and otherde'sirable results in'an easy manner, is cheap'of'construction and positive in results. v 7

Condensed milk, and other similar liquids, are usually removed from the can by male ing two small openings therein, one for the admission of air and the other for the flow o f the liquid.

n. is evident that if the liquid opening be some distance from the periphery of the top,

- all of the liquid can not be poured from the can by the simple tilting thereof, but the latter portions thereofcan be removed only by a shaking process.

It is also evident that the pressed edges of the top around the opening will act as a flange and prevent the removal of all the liquid by a flowing move ment thereof. 7

The, device or my invention overcomes both of these difficulties, as by its employment the opening is made at the extreme pet riphery of the top and the impressed metal is forced flush with the-side of the can, thus offering no impediment to the outward flow of the entire contents when the can is tilted.

Further, when a series of connected openings are made by my device around the outer periphery of the top, the line of sepa- 1 ration forms a smo'othvedge around both the side of the can and the top ofthe can.

presents an effective and practical means for" Application filed, May 1.7,

: The particular", form of the device of invention, shown 1n the accompany ng drawings, comprises -a guide having a secs tor portionlO, capableof placement around the can 11 and-atop member f Finedly attached to the upper face oftherguide member 12, by'the rivets 13,13, isaresilient arm 14. .Movably attached to the othei-" eg q I i tremity ofthearmlgby the screws 15, 15-,

is a wooden handle 16; the screws passing through the slotsQL-gQtof the arm li. .Passa'f ing through a slot 23, within'thearm: 14, .is a punch 17, which is fixedlyattached tothe handle 16 by the extended portion 18, which is driven into the under portion of the handle; Thevouter face of'the punch 17 is flat, 0i slightly cirCular, andthe i n face i bun h re in is circular in the' form of the accompanying drawing a The handle 16 andthe. punch 17, can be 'moved. longitudinally along the arm "14, by

loosingthe screws15, 15, sliding them along, the slots 24:, 24 and. then screwing them in;

tightly when the position. v

The operation of the device is a'sfollows:

punch 17 is in the proper The guidevis placed againstthe side and M top. of a can and, while held inthat position, punch 17 is fixed in proper posit-ion and the handle 16 is pressed firmly f downwardly,

as shown dotted lines of Figure 4:, the punch entering the can top 19. forming an opening. therein. The position of the punch 17, with'respect tothe guide'lO, issuch' that on through the line the outer face of the punch 1'? will practically abut upon the outer edge otthe can top 19, when the punch is This operation forms an opening in tli can top 19, as shown in Figure 6. The portion of the can top 19 around the outer edge of In the modification shown in Figures 4, 5 and 7, a punch 21 is attached to the under face of the plate 26, by means of the rivets 22, 22, passing through the angular member 25 of the punch 21. The plate 26'is fixedly attached to the handle 16 by means of the screws 27, 27, 27, which pass through the slots 28, 28, 28 in the arm 14, thus allowing of the positioning of the punch 21 along the arm 14:. The punch 21 is triangular in shape, the outer face of which is convex to correspond with the circular shape of acan.

The operation of this modifiediorm of my device is as follows The guideand punch are placed, as described above, and the handle 16 pressed downwardly, this producing an elongated opening, or slot, along the outerperiphery of the can top. The guide is then moved slightly and the operation repeated, the openingthus formed producing an elongated opening connecting with the first opening. By repeating this operation, a portion, or the entire, of the top may be cut pressed there through. i

in another portion'o't the can top to admit It is evident that other guide means ma'y be employed andthatthe handle need not be resilient.

I do not limit myselfto the particular size,-shape, number or arrangement of parts, as shown and described, all of whichmay be varied without going beyond the scope of my invention as shown, described and claimed.

'VVhat I claim is 1. In a can opener, in combinatioma segmental guide capable o1"- placement around resilient arm fixedly attached to the guide, a knob carried by the arm and a downward-- 1y extended punch carried by the knob.

3.111 a can opener, in combination, a segmental guide capable of placement around a portion of the edge of a can, a

resilient arm fixedly attached to the guide, a knobcarrled by the arm, a downwardly extended punch carried by the knob and means for positioning the arm and punch at predetermined positions along the arm.
