Specification of Lette rs Patent.

Patented Nov. 27, 1906.

'To all whom it may concern.-

My invention relates to can 0 eners or cut' ters; and its'ohject is to provi e a device of simple construction by the aid of which a can may be cut or opened with great ra idity and with a minimum expenditure of e ort.

The invention includes the combination and arrangement of component parts and the details of construction to be hereinafter described, and particularly pointed out in the claims.

The invention is susceptible of various embodiments without departing from the spirit or scope thereof; but for the purpose of clearly explaining the same it has been deemed necessary toillustrate and describe but a single exemplification of the complete device and a modification of the cutting mechanism proper.

In the accompanying drawings, Figure 1 is a side elevation of the device; Fig. 2, a front elevation thereof; Fig. 3, a transverse sectional view; Fig. 4, an elevation of the modiiied construction of cutting mechanism proper; Fig. 5, a detail view of the same.

ig. 6 is a detail view' of a modified form of connection betweentwo of the gears, and Fig. 7 is a plan View of the stop-arm.

The illustrated exemplification of the invention comprises generally a suitable su porting-frame intended to rest upon or. e secured to a table, shelf, or the like, a cutter for operating upon the can, means engaging the can for supporting and rotating the same during the cutting operation, a hand-operated crank, and drive mechanism interposed between the latter and the supporting devices and cutter. V

The sup orting-frame shown in the accomganying rawings includes a horizontallyisposed base 1, having a forwardl -extending loop ortion for the reception 0 the ed e ofthe ta le, shelf, or the like, and asuitab e screw 2 for clamping the base to the table, and vertically-disposed standards 3 4, preferably cast integral with the-base 1.

The supporting and rotating means for the can, illustrated in the drawings, consists of two disks 5 6, intended, respectively, to coact with the-peripheral edgeor bead at the edge of the u per and lower ends of the can, each of whic disks is preferably provided with a grooved periphery roughened or milled to afford a good gri ping-surface. The disk 5 is shown as secure u on a horizontal shaft 7, which is 'ourna ed in the standards 3 4, and has fixed thereto an operating-crank 8. The disk 6 is arranged beneath and in alinement with the disk 5 and is mounted upon a horizontal shaft 9, ournaled in a bearing-block movably mounted in the standard 3. Suitable drive mechanism is interposed between .the shafts 7 9. The illustrated embodiment of this mechanism includes a vertically-disposed transmission-shaft 10, having a beveled gear 11 fixed thereto at one end, which intermeshes with a com anion gear '12 on the shaft 7, and a second eveled gear 13, keyed thereon and capable of sliding lengthwise thereof, which intermeshes with a companion gear 14 onthe shaft 9.

The shaft 9 is mounted in a movable bearing, as premised, in order that the disk 6 may be shifted toward and from the dlsk 5 to facilitate the placing of a can between the two and for varying the distance between the disks to accommodate cans of varying lengths.

It is preferable that the dlsk 6 be y1eldingly pressed toward the disk 5, and the means for effecting this purpose (illustrated in the drawings) includes a shlftable rest 15 and a suitable spring interposed between the same and the bearing-block for the shaft 9.

Qn reference to Fig. 2 it will beseen that the rest 15 is provided at one end with a hook 16, designed to engage with any one of a vertical series of pins or projections 17 on the front face of standard 3, with a laterally-disposed lug 18, intended to pro ect beneath the bearing-block of the shaft 9 and with an under edge upon the .opposlte side of the lug from the hook 16, designed to engage with one of a series or pins or projectlons l9'on the front face of standard 3. Between the lu 18 and the under side of the bearlng bloc a suitable spring is placed, the same bemglllustrated herein as a leaf-spring, secured mtermediate of its ends to the under side of the bearing-block and having its ends arranged LII its movement by means of the shaft 7, the end of which extends through a slot 27 in the body of said knife.

To hold the can properly centered during the cutting operation and to resist the tendency of the can to ride from between the disks 5 6, a suitable stop 28 is provided. In the accompanying drawings this stop is shown as an arm adjustably mounted on the standard 3, so that it may be moved toward and'froni the vertical plane of the axes of the disks 5 6 in order to accommodate cans of varying diameters and in addition may be thrown entirely out of action, or to the rear of the plane of the disk, so that it will be out of the way in case it is desired to cut a square can, or a can other than a round one is to be operated upon. The arm here shown is provided with a laterally-extending pin 29, revolving in a socket in the standard 3, with which a binding-screw 30 coacts for holding the arm in adjusted position.

The construction and operation of my invention will be readily understood upon reference to the foregoing description and accompanying drawings, and it will be appreciated that the parts and combinations recited may be varied within a wide range without departing from the spirit and scope thereof.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-
