TIMOTHY SHEPARD, OF OSWEGATCHIE, NEW YORK.

MACHINERY FOR DRESSING BARRFL-HEADS.

Specification of Letters Patent No. 6,912, dated November 27, 1849.

To all whom t may concern Be it known that I, TIMOTHY SHEPARD, of the town of Oswegatchie, in the county of St. Lawrence and State of New York, have invented a new and useful Machine for Turning Barrel-Heads; and I do hereby declare that the following is a full, clear, and exact description of the construction and opera-tion of the same, reference being had to the annexed drawings, making a part of this specification, like letters referring to like part-s of the machine, in the several figures, in which- Figure l, is a descriptive view of the top surface. Fig. 2, is a view of the side elevation; Fig. 3, is a view of a cross section, through the center.

A, A, A, A, is a wooden frame.

B, is apulley on an arbor, for a band running fro-m the main drum.

C, a pulley and arbor to be driven by a band from pulley B; D, D, a faced plate with small wedgelike points on the surface, near the circumference, with the edges all parallel with each other; E, E, E, a cast iron shield covering the faced plate D, D, when in motion, having a circular flange extending toward the faced pla-te D, D. It rests and is supported by two arms resting on the pins H, I, and is held to its place by keys L L.

7F is an oblong ho-le cut in the shield from its circumference to the center, with a flange or protuberance. G on the underside, for a rest, and end of .the cut or opening F, a notch M, at the circumference of the shield. H, a circular pin with keyholes, and Key L. I, a square pin, with keyholes, and key L, and notch. K, a small plane on a hinge, so hung as to lit the bevel on the back side of the faced plate D, D, at the circumference, as seen in Figs. l and 3'. L, L, keys to hold the shield E, E, E, to its place. M, a notch on the lower side of the'opening F, at the circumference of the shield, through which the head is turned into a circular sha-pe. N, N, a wooden lever, playing on the point. O, a pin in the frame. P, an iron pin in the lever N, projecting on the back, or inside, toward the machine. a, a, a, a, the top of the machine.

The machine operates as follows: With the machine at rest, and the shield E, E, E, hanging perpendicularly from the pin I-I, as seen in Fig. 2, the lever N, is raised to a perpendicular position, and the pieces of heading, having been previously brought to a uniform thickness, and jointed o-n the edges, are placed edgewise, one on the other, the bottom one resting on the pin P. They are then driven with a mallet or hammer upon the points projecting from t-he faced plate D, D, D, D. The lever is' then returned to its position as Seen in Fig. 2, and the shield E, E, E, E, is raised from its perpendicular to a horizontal position, the lower end resting` in a notch in the square head or pin I, and the keys L, L, are put in their places.

The machine is then set in mot-ion, when with a pointed tool or chisel, used through the notch M, the heading is brought to a circular form. The face'or top of the head is then turned, through the opening F, with a chisel having the right hand corner turned up like a gouge, and smoothed with a chisel having an edge equal to half the diameter of the shield, in length: The plane K, is then brought forward, and in contact with the heading, and pressed down, till it comes in contact with the rear bevel of the faced plate D, D, D. This prepares the bottom, or large bevel of the head,-the Smaller or top one is then turned with a small hand chisel, through the opening F. This finishes the head ready for market, and the coopers use.

The nature of my invention consists in providing a way for turning the face or to of the head, and the edge, and bevels of the saine, at the saine operation.

What I claim as my invention and desire tosecure by Letters Patent is- The application of the shield with the orifice and rest attached to the same in combination with the plane. K to prepare the larger bevel.
