CAN-HEADING MACHINE.

SPECIFICATIQN forming part of Letters Patent No. 307,908, dated November l1, 1884.

(No model.)

To @ZZ whom t may concern:

Beit known t-hat I, JOSEPH BEAKELEY, a citizen of the United States, and a resident ot' Freehold, Monmouth county, Newl Jersey, have invented certain Improvements in Can- Heading Machines, of which the following is a specification.

The object of my invention is to constructa simple and effective device for applying the heads to the bodies of sheet-metal cans; and this object I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which- Figure l, Sheet l', is a front view of the machine; Fig. 2, a longitudinal section of the same, Fig. 3, Sheet 2, an enlarged section of the head-clamping portion of the machine; Fig. 4E, a plan view ofthe same; and Fig. 5, a

, sectional plan on the line l 2, Fig. 3.

A is the base or table of the machine, to which is rmly bolted or otherwise secured an annular frame, B, and to lugs L on the latter are hung by pins b a series of arms, el, each pair of arms carrying a segment, D, of which three are shown in the present instance, these three segments surrounding the frame B, and each segment being acted upon by a spring, e, contained in aradialsocket, f, forming part of said frame B, the tendency of the springs being to force outward or expand the segments D. The outer laces of the segments are inclined, andare acted upon by a ring, F, the latter being connected by rods g to a bar, G, beneath the table. This bar G carries a bolt, h, the upper end of which passes through an opening in one arm of a bell-crank lever, J, hung to lugs 'L' z' on the under side of the table, the other arm of the lever carrying an anti-friction roller, k, which is adapted to a slot, k, in a bar, K, this slot being partly straight and partly inclined, so that as the bar is reciprocated vertically a vibrating movement will be imparted to the lever J. A spring, m, is interposed between the end of the lever J and the bar G, and as the lever is vibrated in the direction of the arrow, Fig. 2, a yielding downward pressure will be imparted to the bar and to the ring F carried thereby, the ring and bar being elevated on the reverse movement of the lever by the action of the latter on the head of the bolt lz.. The bar K is reciprocated by means of a treadle, M, hung to the legs of the table, and thel upper end of the bar is connected to a slotted block, N, rods n a on which are adapted to guides p at the upper ends of the standard I? on the table, the lower end of the guide-rod n carrying the presser-plate S.

On each of the standards I) are two projecting studs, s, which are so located as to form four gages, two for the upper portion and two for the lower portion of the can-body, and the latter is thus properly centered in respect to the segment D, and is'also held in a vertical position, so as to insure its being thrust directly downward into the flanged head coniined by the segments.

The operation of the machine is as follows: The parts being in the position shown in Fig. 2, t-he operator throws a flanged head onto the top ot' the frame D, where it is supported partly by the frame and partly by the radial spring-sockets f. A can being held against the gage-studs s, the treadle is depressed, carrying with it the bar K, the first result of this movement being the operation of the lever J and the depression ofthe bar G through the medium of the spring m. A yielding pressure is thus applied to the bar and to the ring F, and the latter, acting on the inclined outer faces of the segments D, forces the same inward until they confine the tlanged head, the segments being notched so as to overlap the flange. The movement of the bar K continues until the presser-plate S strikes the top of the can-body and forces the same downward until its lower end enters the anged head confined by the segments D, the inner faces of the latter being inclined, so as to impart to the lower end of the can-body any amount of compression necessary to permit the latter to enter the flanged head of the can.

I claim as my inventionl. The combination of the frame B, the hinged segments D, the springs e, the compressing-ring F, and means for depressing said ring, as set fortho 2. The combination of the hinged segment D with the frame B, having radial sockets f, and springs e,contained therein and acting on the segments, as set forth.

3. The combination of the retaining-seg- ICO ments, the ring F, acting` thereon, the bai' G, In testimony whereof Ihave signed my name connected to the ring, the level1 J, the bolt h, to this specification in the presence of two sub- 1o the spring m, and means for vibrating the lescribing Witnesses.

ver as set forth. f

having a slot, k', as set forth. F. C. LooKWoon.
