TIMOTHY NEWHALL, 0F LYNN, MASSACHUSETTS.

MACHINE FOR DRESSING KID-SKINS.

Specification of Letters Patent No. 24,139, dated May 24, 1859.

To all whom 'it may concern:

Be it known that I, TIMOTHY NEWHALL, of Lynn, in the county of Essex and State of Massachusetts, have invented a new and useful Machine for Dressing Kid and other Thin Skins; 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 side sectional elevation of my invention, the plane of section passing through the center. Fig. 2, is a plan or top view of ditto.

Similar' letters or lreference indicate corresponding parts in the twofigures.

The object of this invention is to brush up a gloss on kid and other thin skins after being colored and gummed.

The invention consists in the employment or use of a rotary brush in connection with a reciprocating yielding bed arranged to operate as hereinafter described.

To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.

A, represents a simple rectangular frame having two longitudinal rods B, B, fitted in it, one at each side at its upper part, and C, is a bed or carriage which is attached to or fitted onsaid rods B, bymeans of springs D, D, one at each end of the bed or carriage. The springs are merely iiat metal strips, bent at each end so as to form eyes a, through which the guide rods B, B, pass, the strips being also so bent as to allow a certain degree of vertical play to the bed or carriage. The springs D, are attached permanently to the bed or carriage C, which is allowed to slide freely back and forth on the rods B, B.

The bed or carriage C, is att-ached to an endless belt E, which passes over rollers Z), in the frame A. The axis c, of one of the rollers extending beyond the side of the frame A, and having three pulleys d, e, f, placed thereon, the pulley c, being a working pulley and the others cl, f, loose pulleys.

To each side of the frame A, an upright g, is attached. These uprights form bearings for a shaft on which a cylindrical brush F, is placed. The axis of the brush F, extends through one of the uprights g,

and has three pulleys z', j, lo, placed on it, the central one y', being a working pulley f and the others loose ones.

The uprights g, g, are allowed to slide vertically in the frame A, so that the brush may be adjusted higher or lower to graduate the pressure of the brush on the skin 7', shown in red outline on the bed or carriage, the springs D, D, producing the pressure.

On the working pulleys e, y', a direct and cross belt, shown in red Fig. 2, alternately work, so that the brush F, may be rotated in either direction, the loose pulleys d, c', f, lo, receiving their respective belts when not in use.

The operation is as follows The skin after being properly colored and moistened with gum water is placed on the bed or carriage C, and the brush F, adjusted higher or lower as may be desired, and a reciprocating motion is then given the bed or carriage C, by any proper means, the brush F, being rotated by the belt on the pulleys e, j, and brushing up a gloss on the skin, as the latter passes under it. After a certain interval the motion of the brush F, is reversed by changing the band on the working pulleys e, j, the reciprocating movement of the bed or carriage being continued. This reversing of the movement of the brush is important, as it prevents the skin being roughed up, by the action of the brush, a contingen'cy which would otherwise be liable to occur, in consequence of the continued action of the brush on the skin in one direction. The springs D, D, compensate for any inequalities in the skin, rendering the pressure of the brus about equal on it, its entire length.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is, n

The rotary brush F, in connection with the reciprocating bed or carriage C, connected with its guide rods B, B, by springs D, D, the parts being arranged to operate substantially as and for the purpose set forth.

TIMOTHY ANEWEALL.
