MACHINE FOR CUTTING BARREL-HEADS.

Specification of Letters Patent N o. 20,864, dated July 13, 18581.

T o all whom it may concern:

Be it known that I, A. H. CROZIER, of Oswego, in the county of Oswego and State of New York, have invented an Improved Machine for Turning the Heads of Barrels, Oasks, &c.; and I do hereby declare the following to be a correct description of the same, reference being had to the accompanying drawings, in which- Figure l is a perspective view of the machine complete; Fig. 2, a side elevation of the same showing the cutting tool in position to bevel the edge of the head; Fig. 3, a similar elevation showing the saw in posi ton for cutting the head into the circular form, and the cutting tool removed from the work; Fig. 4, an enlarged view of the beveling tool; and Fig. 5, a vertical section through the disks showing the mode in which they are driven.

The same part is marked in all the figures by the same letter of reference.

The nature of my invention consists in an improved arrangement of machinery for cutting and beveling the heads of barrels, casks &c., in which .both the cutting and beveling tools are controlled by a single winch or lever worked by the operator, and in which it is not necessary to stop the motion in order to put in the material or take out the finished work-all as hereinafter more particularly described.

In the drawings A marks the frame of the machine; B, a loose pulley on the end of the main shaft; O, a fast pulley on the same; D, the main shaft; E, a grooved pulley on D; F, spool on saw shaft; G, dished circular saw; H, worm on shaft D; I, pinion on cross shaft; J, cross shaft; K, pinion on shaft J; L, cogs on lower face of disk; M, lower disk or head holder; N, pulley near end of shaft D; O, band; P, band roller in which the cutter shaft is fixed; Q, beveling cutter; R, upper disk or head holder; S, shaft of the same; T, screw head of S; U, slide; V, guide in which V moves; W', rod connecting U with the rock lever; X, rock lever; X', X', journal boxes of the cutter shaft, which are attached to lever X; Y, pinion pivoted to lever X; Z, rack guide; a, winch working pinion Y; b, stop on rod WV; c, another stop on the same; d, shaft of cutter; e, spiral spring; f, shaft of M; g, socket in which shaft f turns and works vertically; z., upper journal of shaft f.

To enable others to make and use my improved head turner, I will proceed to describe its construction and operation.

I place the machine in a strong frame of iron A; the driving power is applied, from any suit-able prime mover, to pulleys B and C on the end of the main shaft D. This shaft D carries pulleys E and N, and worm H. Pulley E by a cord or band drives spool F on the saw shaft. Pulley N, by band O, drives roller P on the cutter shaft. Worm H drives pinion I on end of cross shaft J. On the other end of said shaft is a pinion K gearing into cogs L on the lower face of disk M. The lower end of the shaft f of disk M works in a socket g attached to the frame of the machine. On this shaft is a collar between which and socket g is placed a spiral spring e through the center of which shaft f plays. The upper part of sha-ft f passes through an upright journal box 71,. The spring e tends to force the collar z' up against the journal box la raising the shaft f' up so that cogs L will be out of gear with pinion K. Above disk M, and

detached from it is disk R attached to shaft S which has a screw thread on its upper portion, as shown, controlled by wheel or head T. By turning wheel T disk R is raised or lowered as desired. Disk R is loosely pivoted to the lower end of shaft S, so as to be capable of independent revolution upon it. When the disk R is brought into contact disk M by screwing down shaft S, the two disks will be capable of revolving together. The disk M, when not pressed down by the disk R is held up by the act-ion of spring e so that the cogs L are out of gear with pinion K, as seen in Fig. 3, and disk M will not be kept in motion by the revolution of said pinion. When, however, the disk R is forced down upon disk M, the spring e, is compressed, and the disk M is lowered down so that cogs L will fall into gear with pinion K and the two disks be revolved by the revolution of that pinion.

The shaft of the dished saw G revolves in journal boxes that form part of the sliding arc U which works in guide V. This guide is connected by rod WV with rock lever X. The rod IV has two stops, a and b, upon it, the end of lever X moving freely between them. The rock lever X is pivoted at its center to the frame of the machine as shown. It moves between guides (see Fig. l) the outer one of which Z has a rack upon its upper surface. Into this rack plays pinion Y which is pivoted to lever X and turned by winch a. Attached to lever X are the journal boxes X X, of the cutter shaft CZ. Fixed to this shaft is roller P which is driven by a band from pulley Y. On the top of shaft Z is the beveling tool or cutter Q. The back and forth movement of winch a will cause lever X to vibrate on its center and bring tool Q up toward, or away from disk M. 'Ihis winch is controlled by the operator.

The operation of the machine is as follows: Power being applied to pulley C, the saw G and cutting tool Q are respectively set in motion by reason of their connection with pulleys E and N. The disk R being drawn up out of contact with M, the cogs L are not in gear with pinion K, and both disks are therefore at rest. The stuff to be turned and beveled is placed on disk M; disk R is screwed down upon it untilv disk M is sufficiently depressed to throw cogs L into gear with pinion K, when revolution will be imparted to both disks and to the material clamped between them. The operator then turns the winch a to the right which brings the saw Gr up to its work of giving the circular form to the head. Vhen that is accomplished, the winch a is turned to the left which withdraws the saw Gr and brings the tool Q up to cut the bevel on the edges of the head. The stops Z) and c on rod W enable the operator to commence bringing up the cutter before withdrawing the saw, and vice versa, thus saving time. When the beveling is accomplished, the disk R, is retracted by means of wheel T; the spring e throws disk M up out of gear with pinion K; its motion is easily arrested; the finished head removed, and a fresh blank inserted for a repetition of the operation.
