JOHN TAGGART, OF MELROSE, ASSIGNAOR TO HIMSELF AND WILLIS N.

BRTNK, or BOSTON, MASSACHUSETTS.

Letters Patent No. 98,121, dated December 21, 1869.

IMPROVE!) MACHINE FOR SCOURING, SETTING OUT, AND PINISHING- HIDES OR SKINS.

The Schedule referred to in these Letters Patent and making part of the same.

To all persons to whom these pTesentsf/nay come:

Be it known that I, JOHN' TAGGART, of Melrose, of the county of Middlesex, and State of Massachusetts, have invented a new and useful or Improved Machine for Securing, ASetting Out, and Finishing `Hides or Skins; and I do hereby declare the same to be fully described in the bllowing specicatio, and` nected by or having a sexies of semicircular and concentric rails, d d, applied to their top surfaces.

The said frame has a series of supporting-legs, e e

e e c, arranged-as represented.

There is pivoted to the frame A, at the junction of its bars a b, a platmn, (l, which, supported inthe frame and the curved rails, is to be capable of being moved thereon in a curved or circular path, and on 'a tubular pivot, f.

There projects from the unde'r side of the platform a semicircular toothed rack, g, which engages with a pinion, h, carried by a horizontal shaft, t.

This shaft, arranged as represented, and supported in suitable bearings, has a crank, It, iixed on its outer end. f

By revolving the crank, the platform may be moved in either direction, forward or backward,in a curved path.

Supported above the platform, and `in boxes l l, fixed in the upper ends of two vertical posts' m m, is a horizontal shaft, n.

A sleeve or tubular shaft, o, encompassesthe shaft a, and is connected therewith so as to revolve with it, and be capable of being moved endwise ou it, the connection being what is termed a feather-connection.7

This hollow shaft o is conc ntric with and has xed to ita drum, p, to whose o ter sulfacc several series of rubbers or slicking-tool ,'r i' r, are applied, each ofsuch tools being snppoted on or against .one or more springs s.

A furcatcd lever, t, pivoted to an arm, u, extended from one of the shaftboxes, spans and enters a grooved wheel, e, fixed 0n the sleeve.

A driving-pulley, fw, fastened on one end of the shaft n, serves to enable the said shaft to be revolved by means ofan endless belt from a suitable motor.

The two box-posts m m rest on helical springs x z, supported on tubular guides f f', through which the posts extend, such posts, at their lower ends, being connected by a bar, y.

A lever, z, resting on the middle of the said bar, is

jointed to another lever or treadle, a', arranged iumanner as represented.

A person, with his foot onl the treadle, can depress yboth of the posts m m simultaneously, so as to bring the cylinder of scooters or setting-out tools down upon a skin or hide when on the platform, or arranged thereon, in manner as shown at H, the springs x a:

serving, as occasion may require, to raise the cylinder out of action upon the hide.

In operating with this machine, the cylinder, when over the middle of the hide, is to be borne down upon the hide, and pnt in revolution. The platform should `next be moved, so as to cause one-half of the hide to be carried underneath the cylinder, so as to be dressed or set out1 thereby.

Lilie operations are to be performed with respect to the other half of the hide, the movements ofthe platform and cylinder being reversed in the performance. In the meantime, endwisc movements are to be im,- parted to the cylinder.

In this way, theuhide may be set out77 or be stretched, and have"`the wrinkles taken out of it to great advantage. y

".lhe moving of the platform in a circular path is far better for operating on a. skin or hide than would be a rectilinear movement ofthe platform.

The combination and arrangement of the rotary series of slickers or tools, mechanism for revolving them, and mechanism moving them endwise, as described, with a platform, and mechanism for imparting to it reciprocating circular movements, as specified.

And, in combination therewith, the mechanism, substantially as described, for raising the tools away ii'om and for depressing them toward the platform, as

explained.
