CAN-HEADING MACHINE.

SPECIFICATION forming part of Letters Patent No. 415,994, dated November 26, 1889.

Application filed February 18, 1889.

To (0% whom it may concern:

Be it known that I, EDWIN E. ANGELL, of Boston, in the county of Suffolk and State of itlassachusetts, have invented certain new and useful Improvements in Oan-Body-Holding Mechanism for Can-Heading Machines, of which the following is a specification.

This invention has for its object to provide improved automatic means for supplying cylindrical bodies to machines in which flanged heads are applied to said bodies and the supporting or clamping said bodies during the operation of applying the heads.

The mechanism which constitutes the subj ect-matter of this application is shown in another application, Serial No. 300,249, filed by me concurrently herewith, for improvements in can-headin g machines, to which application reference may be had for a full description of the general operation of the machine.

The invention forming the subject of this application consists in the details of mechanism,whereby the can-bodies are supplied, held, and released, which I will now proceed to describe and claim.

In the accon'ipanying drawings, forming a part of this specification, Figure 1 represents the can-body supplying and holding mechanism, the clamps being separated prior to being closed upon the can-body. Fig. 2 represents a similar view showing the clamps closed. Fig. 3 represents aview taken at right angles to the view shown in Figs. 1 and 2. Figs. 4, 5, and 6 are views showing the can-feeding uates the same.

The same letters of reference indicate the same parts in all the drawings.

In the drawings, Ct represents a chute through which can-bodies are fed to the mechanism which applies the flanged heads to the ends of the can-bodies, said bodies having been previously formed into cylindrical shape and soldered by suitable mechanism for example, such as is shown in prior applications for improvements in can-soldering machines The cans are allowed to drop one at a time from the chute by a feeding mechanism, hereinafter described, upon a movable support or arm I), which is mounted to swing on a fixed rod or support 6, attached Serial No. 800,250. (No model.)

to the frame of the machine, and is operated by a cam, hereinafter described, so as to stand under the chute a and between the can-body clamps c c, in position to arrest and support a can-body dropping from the chute until the said clamps clasp the can-body, and ,then move away, so as to be out of the way of the devices that apply the heads to the can-body. Said arm or support I) has stops or projections b, which retain the can-body in place and prevent it from moving endwise. The clamps c c are semicircular and are arranged at opposite sides of the point where the can-body is supported by the arm I), said clamps being attached to the upper ends of levers (Z (I, the lower ends of which are pivoted upon the rod 6.

f represented a driving-shaft journaled in bearings in the supporting-frame and provided with a series of cams whereby motion is given to the different parts of the machine. The can-supporting arm Z) has a trundle-roll b", which is engaged with a cam-groove g in a disk g on the shaft f, and is thereby given an 7 5 oscillating motion, as described.

The levers cl d are provided with trundlerolls which enter cam-grooves h in disks h h on the shaft f, said cam-grooves being formed to move the levers (Z (Z and the clamps o 0 8o thereon alternately toward and from each other, thus closing the clamps upon a canbody, as shown in Fig. 2, while said body is supported by the arm I), the cams being timed to hold said clamps upon the can-body while the heads are being applied thereto, and to then separate the clamps and to allow the headed body to drop into a chute j, through which the can-bodies pass from the machine to another machine or floater which solders 9c the heads.

The cans are released from the chute a one at a time by a feeding mechanism composed of two slides or arms A A, which project in opposite directions into slots D D in said 9; chute, and are connected to a shank or holder B, which is attached to the upper end of a lever O. Said lever is mounted to swing upon the rod 6, and has a trundle-roll F, which enters a cam-groove G in a disk H on the shaft I00 f. The rotation of said disk oscillates the lever O and causes it to reciprocate the slides A A and thereby simultaneously move one slide into and the other out of the chute a. Said slides are separated by a space about 1 equal to the diameter of one can-body, and

when the lower slide A is moved out from the chute the can-body thereon is released and allowed to drop, the slide A being at the same time moved inwardly to arrest the next can-body above. After the discharge of the can-body the slides A A are moved in the opposite direction, the slide A being thus moved into the chute to arrest the lower canbody, which is allowed to fall upon it by the outward movement of the slide A.

It will be obvious that the devices above described for letting 01f, clamping, and releasing can-bodies may be used with any other suitable mechanism for applying heads to can-bodies while they are clamped, my invention not being confined to the can-applying devices shown in the above-named application.

The clamps c c are adjustably secured to the levers d (l by means of bolts a passing through slots in the shanks of the clamps. Screws 0 working in tapped sockets in ears on the let ers (I, support the clamps at any point to which they may be adjusted and p revent them from slipping on the bolts 0 I claim 1. In a can-heading machine, the combination of the can-body-delivering chute a, the connected slides A A arranged at different heights in the chute, the lever O, supporting said slides and pivoted at one end to a fixed support, and the shaft f, having a cam G, engaged with said lever, as set forth.

2. In a can-heading machine, the combination, with a can-body-delivering chute, of the clamps c c, mechanism for opening and closing the same, a can-supporting arm, and mechanism for holding said arm alternately under and away from the clamps, as set forth.

3. I11 a can-heading machine, the combination, with a can-body-delivering chute, of the clamps c c, the levers d d, supporting said clamp, the cams h h, whereby said levers are oscillated, the supporting-arm b, and the cam g, engaged with said arm, all arranged and operating substantially as described.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 31st day of January, A. D. 1889.
