CHUCK FOR CUTTING BARREL-HEADS.

Specification of Letters Patent No. 10,228, dated November 15, 1853.

To @ZZ whom t may concern.'

Be it. known that I, FRANKLIN FRUIT, of Jefferson City, in the county of Cole and State of Missouri, have invented a new and useful Improvement in Machines for Cutting Barrel-Heads; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l, is a plan or top view of the machine. Fig. 2, is a face view of the chuck.

Similar letters of reference indicate corr spending parts, in each of the two figures.

The nature of my invention consists in holding the material of which the barrelhead is cut, by means of a chuck, having a series of centers, placed in circular form, and concentric with the periphery of the chuck. Each center is provided with a spiral spring, which enables the centers, individually, to give or yield, so that the different. pieces formingk the barrel-head may vary in thickness, and still be firmly held by the chuck, as will be presently shown.

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

A, represents a mandrel, or shaft, on one end of which a face-plate, B, is secured.

O, is a mandrel, or shaft, on one end of which a chuck, D, is secured, and which chuck will be hereafter fully described. The two mandrels, or shafts, A, O, are placed in line, and work or run in suitable bearings, supported by a frame, constructed in any suitable manner.

The stuff or material from which the barrel-heads are cut, is secured between the face-plate, B, and the centers of the chuck, D.

The chuck is formed or constructed of two circular disks, (a), connected by studs, (c), of such a length as to allow a requisite space between the disks. These studs are screwed into the front disk, (a), and their opposite ends pass through the back disk, (b), and have nuts, (d), upon them, which nuts are screwed firmly against the outer surface ofthe back disk. The studs are placed all around the disks, and near their edges, forming a circle, concentric with the peripheries of the disks.

Between the studs, (c), are placed centers, (e), which pass through both the front and back disks. The centers have collars, (f), upon them; and between the collars and the inner side of the back-plate, and upon each center, there is placed a spiral spring, These springs, of course tend to throw the points of the centers firmly against the stuff or material, represented by, E.

Barrel-heads are formed of several pieces; and these pieces often vary in thickness. Now, by placing the several pieces against the face-plate, B, the centers, (e), will press each piece firmly against the face-plate, no matter whether it is thick or thin; for, if thick, the springs will allow the centers, against which the piece is in contact, to yield or give sufficiently to allow the perfect adjustment of the piece, between the faceplate and centers; the centers holding or pressing it firmly against the face-plate. If the piece is thin, the springs will force the centers forward and against it, and with sufficient pressure to keep it firmly to the face-plate.

In Fig. 2, the red lines indicate a barrelhead, and the several pieces of which it is formed.

It will be seen, by the above arrangement, that each piece of a barrel-head may dier in thickness from the others; and, as each center is provided with a spring, and works independently of the others, each piece may be properly secured between the face-plate and chuck.

The mandrels, or shafts, A, C, are provided each with a screw, F, at their outer ends, by operating which, the face-plate and chuck may be brought nearer together, or placed farther apart, as desired.

G, G, are two slides, which contain cutters, H, I, for cutting the bevels on the periphery of the head; and also, a cutter, J, for cutting the head in circular form, or of the proper circumference.

The slides are moved, longitudinally, by means of levers, K, K, the tops of which are seen in Fig. l and they are moved, laterally, by means of screws, Il, L, Ii.

The slides and cutters, and also the manner of operating them, are well known and familiar devices, and require no further description.

I do not claim the slides, nor the cutters, nor any particular manner of operating them; but,

I-Iaving described my invention, what I claim as new, and desire to secure by Letters Patent, is,

The chuck, D, constructed substantially independently of the'others, so that the different pieces forming the barrel-head may Vary in thickness, and still be properly adjusted and secured between the face-plate A(ind chuck, as set forth in the body of this specication.

FRANKLIN FRUIT.
