IMPROVEMENT IN LEATHER-SCOURING MACHINES.

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

Iof this specification.

The drawing represents aside view, partly in section, of our improved leather-scouring machine.'

'lhis mvcntion relates to a new manner of arranging a self -adjusting bed or table under the rotary scouring-cylinder of a leather-dressing apparatus, and to a novel method of securing the scouring-stones and brushes iu alternate rows to the said cylinder.

The vinvention consists in supporting the adjustable bed by springs, andguidiug it, by means ot jointed pns'working in tubular sockets, so that thereby the bed will be adjustable iu every.direction and automatically held against the scouring-implements.

rlhe invention consists also in securing the scouringstones tothe cylinder by means ofthe blocks to which the brushes are fastened, so thatthereby alternate rows `of stones and 'brushes arc produced..

in the drawing represents the scouring-cylinder. It is made ofmetal or other material, and carries stones B and brushes C on its rim. The stones are enlarged toward their bases, and are wedged in place by the wooden orother blocks a, to which the brushes are secured, said blocks being, by means of bolts b b, secured to the cylinder, as shown. 1n this manner the stones are securely held.

The rows of stones and brushes may be straight, laterally, or somewhat spiral', as may be desired. Each row is either entirely of stone and brush, or' made of alternating sections of either, the next row having the opposite sections of the other material.

'lhc scouringvlinder is hung in a pendulum-flame,

D, or in ixed bearings.

.E is the adjustable bed, upon which the leather to be dressed or scoured is placed. This bed is arranged above ar fixed table, F,.audis, by springs c c underneath, held against and in contactwith the scouringcylinder. 'lhese springs are disposed in suitable man- T161'.

The motion of the adjustable bed is controlled by springs d, which project from the under side of said bed into hollow sockets e e, held bythe table F. The

pins rl, however, are jointed, as at f, to give greater variety of rnotion to the bed.

The upper face of the bed is concave, and over it'is stretched, by being fastened to the ends, a sheet, V G, of rubber, leather, or other flexible or seinieelastic material. for the material to-be treated.

The leather to be scoured'or dressed is placed upon the sheet CI, and the same, by the springs e, held against the revolving cylinder, whereby the desired object, under a suit-able degree of pressure, is fully :1ttained.

Having thus described ourlnventxon We claim as new and desire to secure by Lettersv Patentl. The yielding bed E, supported by springs c, and I guided by jointed pins d, substantially as herein shown and described.

2. The sheet Gr, stretched over the' concave surface of the adjustable bed E, to constitute an elastic cushion thereon, substantially as herein shown vand dcscribed. A Y

'3. The scouring-cylinder containing the stones and brushes in alternate rows, the stones being secured by the blocks a, to which the brushes are fastened, substantially as herein shown and described.
