IMPROVEMENT IN MACHINES FOR MAKING BARREL-HEAD-S.

Specification forming part of Letters Patent No. 209,311, dated October 22, 1878; application led September 25, 1878.

To all whom it may concern:

Beit known that I, ABRAHAM WAsoN, of New Boston, in the county of Hillsborough and State of New Hampshire, have invented certain new and useful Improvements in Machines for Cutting and Shaping Barrel-Heads, of which the following is a specification:

This invention relates to an improved machine for cutting and shaping barrel-heads, and it has for its object to provide an apparatus in which the heads may be automatiwhich it may be caused to approach to or re cede from the other, which is lixed, in order to automatically seize the blank and hold it during the operation of the cutters, and' release the head when completed, as more fully hereinafter specified.

My invention also consists in the combination, with the clamps and rotary cutter-heads, of a guide for directing the insertion of the blank, and automatically-working stopping devices for holding the blank until the preceding head has been cut and discharged from between the clamps, as more fully hereinafter speciied.

My invention further consists in the combination, with the clamps, of an automaticallyoperating releasing device, for releasing the qfinished head from the clamps, as more fully hereinafter set forth.

In the drawings, Figure 1 represents a front elevation of my improved apparatus. Fig.,2 represents a rear elevation, and Fig. 3 represents a top view, of the apparatus.

The letterA represents the frame of the machine, which carries the workin g parts thereof. The letter B represents two clamping-disks,

and mounted upon cylindrical bars C G1, eX

tending through the hollow shafts D of the cutter-heads DI, which are journaled in bearings E in the frame A. The hollow shafts are each provided with a pulley or drum, F, by which a rotary motion may be imparted to the same; and the cutter-heads each carry an angular cutter, G, by means of which the barrelhead is cut from the blank and chamfered at its edges.

At the rear of the pulleys, on the hollow shaft of each cutter-head, are secured collars H, which are embraced by the branches K at the ends of the bifurcated levers L, fulcrumed to the frame A, the opposite ends of said leshafts. Each of said levers is provided with an extension, T, rising vertically, and then extending horizontally to the center of the frame, where they terminate in bifurcated branches A. The said extensions move to and from each other when the machine is in operation, and form a stop for regulating the insertion of the blank, as more fully hereinafter specified.

The letter B represents the guiding devices,

' which consist of upright standards rising from the frame of the apparatus above the clamps and the stops, a space being left between the two for the insertion of the blank to be fed into the machine.

The levers S and Sl are provided at their outer ends with friction-rollers C2, whichfsit in cam-grooves D2 in the drums L on the shaft P, by which the levers are given an oscillating movement.` The lever Sl serves to reciprocate the bar C1 of the clamp, so as to cause the same to approach and recede from the opposite clamp at proper intervals to seize the blank and subject it to the action of the eutters. Said lever also serves to actuate the extension T1 of the stop, the other lever, S, serving to actuate the opposite extension, so as to operate in unison therewith, and riding free of the clamping-disk bar C, which is stationary.

To the lever S is secured one end of a lever, G', fulcriuned to the frame A, the other end of which is pivoted to a cross-bar, H', to which are attached the reciprocating rods K', mounted in ways or guides L" in the frame, and to which are attached the upwardly-extending arms, M', which sit just behind the stationary clamp, and serve, when thrust forward to force the finished head away from the stationary clamp, to facilitate the discharge of said head from the machine.

The shaft P is provided at one end with a gear-wheel, P', which engages a pinion on a shaft, R', journaled at one end of the machine,

said pinion being provided on its front face with a ratchet, S2, and being capable of a longitudinal movement on its shaft, controlled by a lever, T2, by means of which it can be thrown into and out of gear with a similar ratchetwheel on the hub of a loose pulley, U2, mounted on the same shaft, whereby the shaft may be putin motion or stopped at will.

The operation of my improved apparatus is as follows: The hollow shafts of the cutterheads being put in motion, as well as the shaft I), the reciprocating clamp will be caused to travel back and forth toward the stationary clamp. At the same time the stopping devices will be caused to approach to and recede from each other, and the cutter-heads will also be caused to approach to and recede from the work. The work is fed in between the guides, and is held by the stops, which close together at the proper time, until the reciprocating head has receded from'the stationary head and the two clamps arein position to receive the blank. When in this position the stops have receded from each other, permitting the blank to be fed in between the clamps, by which it is seized when the cutters advance andcommence their work upon the blank. When the head is cut and severed therefrom the parts again assume their normal positions, ready for work upon the succeeding part of the blank.

What I claim is- 1. In a machine for making barrel-heads, the combination, with the clamping-disks B, their shafts C (ll, the cutter-heads D', and their hollow shafts D, of the collars H onthe latter, the pivoted levers K, attached to said collars, and the drumsOon the shaftP,havingcam-grooves, in which the ends of the levers K are arranged, substantially as and for the purpose described.

2. The combination of the following element-s, to wit: the clamping-disks B B, their shafts C C', the cutter-heads D, their hollow shafts D, and mechanism for reciprocating the same, the pivoted lever S, pivoted to one of the clamp-shafts, and the drum L', having a cam-groove, in which the end of the lever S is arranged, substantially as and for the purpose described.

3. The combination, with the stationary clamping-disk and its shaft, of .the Vertical releasing bars M', the rods K', cross-bar H', vertical pivoted lever G', and a horizontal lever, S, attached at one end to the lever G', and having its other end arranged in a cam-groove in the rotating drum L', all arranged to automatically move the bar M' to discharge the finished barrel-head, substantially as shown and described.

4.. The combination, with the clamping-disks B and rotary cutters Dl of a machine for making barrel-heads, of the upright standards, forming guides B', facing each other and arranged above the disks and cutters, the bifurcated branches A', and mechanism such as described for automatically reciprocating said branches, as and for the purpose described.

5. In combination with the stationary clamping-disk and the rotary cutter, the releasingbars, automatically operated by suitable mechanism to discharge the finished head, substantially as specified.

In testimony that I claim the foregoing I have hereunto set my hand in the presence of the subscribing witnesses.

' ABRAHAM WASON.
