Specification of Letters Patent.

Patented July12, 1910.

Application led November 6, 1909. Serial No. 526,556.-

To `oZZ whom 'it may concern: e

Be it known that I, CLINTON Anno'rr, a citizen of the United States, residing at Zinc, in the county of Boone und State of Arkansas, have invented new and useful Improvements in Can-Openers, of which the following is a specification.

Thisinvention relates to that class of can openers that are adapted to open cylindrical sealed cans by cutting an approximately circular piece ofthe tops thereof, and the invention has for its object to provide a machine of simple and inexpensive construction which ma be easily and quickly manipulated to e'iiect the desired result.

A further object of the invention is to provide a machine of the class indicated which may be readily adjusted to operate upon cans of different sizes and diameters.

Further objects of the invention are to simplify and improve the construction and 4 operation of this' class of machines.

With these and other ends in view which will readily appear as the nature of ythe invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention; it being however understood that no limitation is necessarily made to the precise structural details therein exhilnted, but thatj changes", alterations and modifications within the scope of the invention may be resorted to when desired.

In the drawings: Figure 1 is a side elevation of a can opening machine'constructed in accordance with the invention. Fig. 2 is a Vertical sectional view of the same. Fig. 3 is a top plan view of the machine somewhat enlarged. Fig. 4 is a horizontal sectional view, enlarged, taken on the line 4-4 in Fig. 1. Fig. 5 is 'a sectional detail view taken on he plane indicated by the line 5-5 in Pig. 2.

Corresponding parts in the several figures are denoted 'by like characters of reference.

'lhe frame of thc'improved machine comprises a. pair of uprights which for convenience will be deseri-'nsd as the front and rear uprigbts (3 and 7; .the same being mounted upon a base 8 and connected-at their upper ends by a bridge piece or cross piece 9. The rear upright is provided with a transverse slot 10 intersected by a longitudinal slotll; extending through, 4and vertically adjustable in the transverse slot 10 is a clamping screw 12 having a wing nut 12 and serving as a pivoter fulcrum' for a lever L which is free to operate in the' slot l1, said lever being provided at its front end with a handle 13. The lever L extends through a. slot 14 formed in the front upright 6, said slot being provided upon one of its side walls withteeth -or ratchets 15 with which the lever may be placed in engagement, by slightly tilting said Ilever which may thus be retained in position at various adjustments. Pivotally mounted in thc slot 14 near the lower end of the -latter is an arm 1G which is connected with the lever L by means of a link 17; a shank 18 that extends through an aperture in the arm` 16 carries at its rear end a gripping jaw 19 having a curved serrated face 20. mating gripping 'jaw 21 is formed upon a shank 22 'that extends from therear upright 7 with which it is se= curely connected. An auxiliary grip ing jaw 23 correspondingr with and locate in the vertical plane of the rear jaw 2l is secured upon the base 8 directly below `said jaw 21. l

The top piece or bridge piece 9 of the frame is provided with a longitudinal slot 24 and a corresponding slot 25 1s formed in a slide 26 which is secured adjustably upon the bridge piece by means of a set screw 27 operating through the slot 25. The slide 26 affords a bearing for a vertical shaft 28 having at its upper end a crank29 .whereby it may be rotated. The shaft 28 extends through the slot 24 in the bridge piece 9 and through a slot 30 in the lever. L. The lower extremity of the shaft 28 carries a cutter head 31 abuttin u on the underside of the lever L and the s a t 28 is provided with a sleeve-or collar 32 adjacent to the upper side of the leverwith which the shaft 28 is thus op fulcrum of the lever. The cutter head 3l terminates at itslower extremity in a conical point or prong 33; and said head is provided with a transverse slot 34 wherein a shank 35 having a downwardly extending cutting blade 36 is adj ustably securedf by means of-a set screw 37.

cratively connected for rotation and for adjustment at various distances from the The shank 18 carrying the gripping jaw 1.9 is mounted adjustably in the arm 16 by Ineans of a set screw 38.

From the foregoing description, taken in' Adjustment of the machine to operate upon cans of various heights and diameters may be had by vertically adjustinur the fulcriun i. member l2 of the lever L, by xiongitudinally adjusting theshank 18 carr mg the gripping jaw 19, and by laterally a justing the slide 26 which forms the bearing for the shaft 28 carrying the cutter head. After proper adjustment of the parts ofthe machine, the can is placed in position upon the base between the ripping jaws; by depressing the handle of t ie lever L, the jaws will be caused .to firmly grip the can, and at the same time the cutter head earryinw shaft will be depressed until the top of tie can is punt-.t ured by the prong-33 and by the blade 3G. The pron(r 33 serves to support the lower end of thel siat't while the latter is being rotated by the crank 29, thus causing the top of the can to be cut out by the blade or cutter 36.

Having thus described the invention, what is claimed is l.. In a can openingmachine, a .frame comprising two uprights and a bridge piece connecting the same, said uprights being provided with slots, a fulcrum member vertically adjustable in a slot in one upright, a lever pivoted upon said fulcrum member and guided through a slot in the other upright, a shaft carried by the lever and having a crank at one end, and a cutting device at the other end, a gripping jaw connected With one upright, an arm pivoted upon the other upright, a gripping jaw having a shank adjustably engaging the pivoted arm, and a link connecting the latter with the lever.

2. In a can oaening machine, a frame, a longitudinally slotted lever, adjustably con-V nected with the frame, acutter carrying shaft extending through the slot in the lever and through a corresponding slot inthe frame, means connecting the shaft with the leverfor vertical movement therewith, and a slide adjustably connected with the frame and affording a bearing for the cutter carrying shaft.

3. In a can opening machine, a frame in cluding a. longitudinally slotted bridge member7 a lever adjustably connect ed with the frame and having a longitudinal slot, can gripping means connected with and actuated by the lever, :1y shaft. extending through the slots in the lever and in the bridge piece of the frame, a cutter head u on the shaft abutting upon the underside ot the lever, a sleeve upon the shaft abutting upon the upper side o the lever, and a slide adjustably mounted upon the bridge member of the trarne and affording a bearing for the. cutter carrying shaft.

ln testimony whereof I ailx my signature in presence o tl two witnesses.

CLINTON ABBOTT.
