MACHINE FOR CUTTING BARREL-HEADS.

Specicaton of Letters Patent No. 9,565, dated February 1, 1853.

To all whom t may concern Be it known that I, CHARLES B. HUTOH- INsoN, of IVaterloo, in Seneca county, in the State of New York, have invented certain new and useful Improvements in Machinery for Turning the Heads of Barrels; and I do hereby declare that the following is a full, clear, and eXact description of the construction and operation of the same, reference being had to t-he annexed drawings, making a part of this specification, in which* Figure l, is a perspective view of the machine. Fig. 2, is a transverse vertical section of the same, taken through the center. Fig. 3 is a side view of the cutters which cut out and bevel the head. This view is de signed to show the mode in which the said cutters are moved forward. Fig. l is a section, showing one of the two small yokes which clasp the shoulders of the clamp rings.

Similar letters of reference indicate corresponding parts in each of the several figures.

My invention relates to certain improvements in machinery for cutting or turning the heads of barrels or casks, andconsists in the use o-f clamp rings to hold the wood for the head and present it to be cut and dressed by rotating' cutters; said cutters being arranged upon a rotating disk and arms, in a peculiar combination to be hereafter described in detail, in such a manner that the head may be cut out, face dressed, and beveled or chamfered on the edge, by a single operation.

To enable others skilled in the art to make and use my invent-ion, I proceed to describe its construction and operation.

A, represents the frame of the machine.

C is a shaft, and upon one end of the shaft C, is iXed a disk J, (Figs. l and 3), carrying three cutters K, K, K, which eX- tend from t-he center of the disk nearly back to its edge, designed to dress 0E the head to a smooth face. Directly behind the disk, and carried and rotated in like manner by the shaft C, is a collar L, (Fig. 3), from which extend three arms or flanches, carrythe tools (g) (g) (g) designed for cutting out the head and beveling its edge, viz., a flem knife which cuts out the circle, followed by a chamfering knife which cuts the bevel. These tools project beyond the disk, which is cut away to admit their passage, so

as to cut a uniform chamfer to any required depth below the surface to which the ywood is dressed by the cutters K, K, K; and they are also adjustable by means of set screws so as to cut heads of any required diameter. The collar L, also slides upon the shaft C, and by means of a forked lever M, litted into a recess (e) and worked by t-he foot, may be thrown forward so far that the tools (g) (g) (g) will cut through the wood before the cutters K can act upon it. This will always be done when the inner face of the head is cut, as that does not require to be dressed off.

N, N, are clamp rings, designed to hold the wood from which the head is to be cut. The ring N, which I will call the upper ring, is attached by opposite shoulders to the small disks (l5) (is), in which are centered pivots (7L) (h) (one of which is seen in Fig. l), by which it is suspended upon and between the ends of the parallel slides O, O, working in the frame A, in such a manner that when the slides are drawn out it may be turned complet-ely around. The under ring N', is suspended upon the upper by means of small yokes, (j) (j), (seen in Figs. 1 and 4) clasping the shoulders of both, and is drawn up and held firmly against the wood placed between them by means of the eccentric handles or levers P, I), attached to the yokes. The teeth (z') upon N secure the wood when the pieces are not of equal or uniform thickness.

To use the apparatus, suppose the slides O, O, drawn out, and the rings in a horizontal position; the pieces of wood are placed between them, and they are strained together by means of the eccentric handles P, P; the rings are then turned to a vertical position, (in which they are secured by a small pawl R, fitting into a proper recess, seen in Fig. l), and moved up toward the disk J, so that the rotating cutters K, K, K, and (g) (g) (g) may act upon the wood. The outer face being thus cut and dressed, the rings are drawn back, reversed, pushed up again, (the collar L, being thrown forward by means of the lever M,) until the wood is cut through and the head falls out.

Having thus fully described the construction and operation of my machinery, I proceed to point out the parts and combinations which I consider novel and essential. In relation to the head turning apparatus, I am aware that there is nothing novel in the use of clamp rings as such, or of rotating cutting tools, such as flem knives, ehamfering chisels, and aee planers, set on disks or otherwise; but the peculiar combination and arrangement of all these which I have adopted, I believe to be Wholly novel and not heretofore used, either for the purpose herein specified vor any other.

What therefore I olaini as new, and desireA to secure by Letters Patent is- The use of clamp rings N, N, to hold the pieces of heading, and hung in bearings on opposite sides, or in any equivalent Way so as to be reversible, in combination With the adjustable rotating cutters (g) (y) (g) 15 be successively presented to the action of the 20 cutting tools, and the head Cut out, chamfered, and face dressed, or out outl and chamfered only, at one operation.
