This invention relates to can openers. Objects of the invention are to provide an improved canopener comprising a rigid support having a cutting member rigid thereon and designed and arranged to cut through the end wall of a can when the can is rotated in the proper manner, in combination with an arm pivotally supported by said member and carrying a feeding roller in position to engage f the rim around the end wall of the can, a spring for actuating said arm constantly in a 'manner to cause the feeding roller to hold the can against and in engagement with said cutting member, and a crank in connection' J with the axis of said'feeding roller and movable therewith for rotating said feeding roller to rotate the can; to provide improved means for/operating said arm to permit application n and removal of the can; and to provide de vices for functioning as an abutment for the end of the can and against which the end of the can operates when the can is operated.

@ther objects will appear from the following description. reference being made to the accompanying drawings, in which- Fig. 1 is an outer side elevation of my improved can opener, a portion of the handle being broken away, and a release device being o adjusted to hold the feeding roller in position to permit application and can.

My improved can opener comprises a bar plate 1 preferably composed ot'V metal and `having near one end a tended ears 2. .The loweredges of the ears 2 are in the same horizontal plane and function as abutments against which the margin of the upper .end of the can 3 engages. when the can isy attached to the opener. r1`he ears 2 are spaced apart. The bar or plate 1 is formed with a laterally extended portion 4 extending upwardly from between the ears 2. A

cutting member,

rigidly attached to the part 4 by fasteners 6.

The lower end of the` jects below the lower end of the part 4 and is spaced from the bar or plate 1,'as indicated at 7 (Fig. 5). The lower end of the part 4 1s in the same horizontal plane with or above the horizontal plane of the lower edges of the ears 2 in order not to interfere with the positioning and removal of the can 3. rllhe lower corner 8 of the cutting member 5 constitutes a cutting edge that will cut through the upper end wall 9 of the can 3 close to the wall of said can 3 when the can is applied to the device and rotated.

An axle member 10 projects through a slot 11 in the bar or plate 1 and has a feeding roller 12 attached to one end thereof and is below the part 4. A washer 13 is loose on the axle v member 10 and is located between the feeding roller 12 and the adjacent surface of the plate or bar 1, thus holding said feeding roller slightly spaced from said plate or bar 1.

v An arm 14 has one end mounted on a pivot 15 carried by the outer end of the plate or bar 1. Said arm 14 is formed with a slot 16 through which extends a guide 17 in the form of a pin rigid with the plate or bar 1 and projecting therefrom through said slot. 16 and having a head on its outer end reventing outward bending of the arm 14. sleeve 18 is attached to the arm 14. The axle 10 projects through the arm 14 and through the sleeve 18 and has a crank arm 19 detachably secured to its outer end by a removable and replaceable nut 20. The lever 19 has a handle 21 on its free end whereby said lever may be operated to rotate the axle 10 and thereby the comprising a blade 5, is

pair of laterally exi cuttingr member profeeding roller 12. A strong spring 22 has site end engaged with the bar or plate 1 and is eective to actuate the free end ofthe arm 14 upwardly in a direction ,to move the feeding roller 12 toward-the part 4.

A lever 23 is mounted on a pivot 24 carriedby the bar or plate 1 and has a ca member 25 (pn oneend and a handle 26 on i lopposite en The bar or plate 1 `is formed with alateral The arms 28, 29 and 30 are engaged within the guides provided by the engaging portions 32 and the deviceis thereby supported due to the downwardly converging relationship of the parts 32 and the inclined ends of the arms 28, 29 and 30. .Fasteners 33 will hold the bracket in rigid connection with a wall or other support.

This device is used by operating the lever- 23 to the position shown in Figs.'1 and 2, causing the cam 25 to push downwardly the end of the arm 14 in opposition to thel power of the spring 22. In this position, the feeding roller12 is some distance below the point 8 of the cutting member, so that the bead 34 formed by the crimped'engagement of the end wall 9 with the side wall 3 of the can may be seated upon the 'upper peripheral ortion of said feeding roller. In this position, the cutting corner 8 of the cutting member is on the inside of the bead 34-in position to" be `forcedthrough the end wall 9 of the can.

Then the lever 23'is operated to the position shown in Figs.. 3 and 4, permitting the spring 22 to retract. When the spring 22 retracts, it draws upwardly the end of the arm 14 'and thereby the -feeding' roller 12,

thus causing the cutting corner 8 to cut- Vthrough the end wall 9 of thecan. This action f the parts moves the can upwardly to a position in which` the upperedge of the bead 34 is against the lower edges of the ears 2. The relationship of the cutting member to the bead 34 and the fact that the bead 34 isagainst the inner surface of the lower end of the cutting member hold the can in proper relationship, so that when the feeding roller 12 is rotated, the can will therebybe rotated, causin the cutting member to cut cleanly throug the end wall of the can so that said end wall maybe removed. The-can will be supported bythe can opener until the lever 23 1s again oper- 1 is split and ated to the position shown in Figs. 1 in order to release thebead 34 `from its clamping engagement between the partsv 2 and 12. Preferably the periphery of the feeding roller 12 is notched orknurled in order to obtain effective ripping engagement with the lower edge of t ef bead 34 to assure rotation of the can when the feeding roller is rotated.

A stop 35 for the lever v23 is rigid on the support 1 and prevents overthrow said vlever, and holds said lever in the position shown in Figs. 1 and 2. In this position, the can 3 may be applied or removed because the pressureof the feeding roller ,12 against the bead 34 is released.

This device may be manufactured at comparatively low cost and obtains all of and2 'i and sold its intended objects and purposes in an effective and satisfactory way. The construction andsarrangement of the parts may be varied within the scope of equivalent limits without departure from the nature and principle of the invention.
