MACHINE FOR TREATING HIDES AND SKINS.

SFECIFICATIONforming part of Letters Patent No. 256,326, dated April 11, 1882.

Application tlledFebruar-y 7, 1882.l (No model.)

To all whom it may concern:

Be it known that I, JOHN MEREDITH JONES,

a subject ofthe Queen of Great Britain, and

My invention relates to a machine for tleshing, scudding or cleansing, striking out or v slicking, skiving or frizzing, unhairing, or laying out hides, skins, or leather, as may be necessary within the meaning of the several terms which are well known and understood among hide, skin, and leather dressers. p

My invention relates more particularly to machines of that class in which an endless 'band is combined with a roller having thin riphery of the roller; and the main object of my invention is to so construct such a machine that the leather or other article to be treated can be readily inserted and withdrawn. This object l attain by mounting the said roller in bearings in arms, which can be raised and lowered on the main frameby means of a treadle or other convenient device, as more fully described hereinafter. Y

Figure l of the accompanying drawings is a side elevation of my improved machine for treating hides, skins, or leather. Fig. 2 is an end elevation of thel same, and Fig. Sis aplan corresponding to Fig. 1.

a is a frame-constructed to carry the various rollers and gearing.

b is a roller having thin projecting strips of metal arranged spirally on its face, each strip running spirally and in opposite directions from the middle part of theroller-i'ace toward each end. This spiral-face roller b is so arranged thatY it may be raised out of contact with the endless band by means of the weighted lever t', the lever 'e'. bein g so constructed in this arrangement that the application of the vvOrk-. mans foot to the treadle-board `h raises the weight o and causes the roller b to be brought into contact with the endless band y; but the lever i, or its equivalent mechanical device, 'may be so arranged that the application of the workmans foot or other force shall raise the roller b out of contact with the. endless band, while it may be brought into contact by means of suitably-arranged weights'on theremoval of the opposing force. The vertical movement of the spiral-face roller b,- and consequent pressure on the endless band y, is governed by the set-screws Z, which are adjustable and regulate the travel of the end of the lever t'.

Behind the spiral-face roller b are placed three rollers, g g o, acting as retaining, traveling, and tightening rollers.

m represents radial arms attached to the frame a for carrying, raising, and lowering the spiral-face roller b.

n is a running-nut with right and left hand screws for tightening and retaining the spiralface roller at a greater or less distance from the surface ot' the endless band.

y is an endless band carried on two drums, e d, 'thedrum e being adjustable by means of set-screws lc for the purpose of stretching the band ti ghtlyg. The drum d is caused to revolve, and consequently to move the endless band y, by means of the gear-wheels 2 3, which are driven by the main driving-shaft r.

q q are y-vrheels fixed on the main shaft 1. i

s represents spur-wheels for driving the spiral-face roller.

tis a balance-lever, on which-a scraper is placed tor cleaning the endless band y.

a is a balance-weight attached to lever t. v w represents a water-pipe tted with jets for lubricating the endless band y.

Motion is given to the spiral-face roller b `from the main driving-shaft r, which is itself driven by a beltl running on the fast and loose pulleys p p.

In the drawings, the machine is shown containing all the parts necessary for the purpose ot iieshing, scudding or cleansing, frizzing, un-` hairing, or laying out hides, skins, or leather, as may be necessary.

The machine operates in the following manner: Motion being given to the spiral-face roller and the endless band, I place on such endless hand a skin or hide to be operated on as the skin or hide travels forward on the band until it reaches the retainingroller c, when by means of the treadle h and lever 'i the spiral roller b is brought into contact with the skin and such pressure given to thespiral-face roller b by the operator as may be necessary to perform the operations already enumerated. This spiral-face roller b extends the skin in every direction and performs the various operations of iieshing, scudding or cleansing, striking ont or slieking7 frizzing, unhairing, and laying out. In order to give greater s0- lidity to the endless band when it is desirable to give greater pressure on the spiral-face roller, the roller f is raised by means of setserews against the endless band y.

I claim 1. The combination of an endless band and feed-rollers with :t spiral-faced roller, movable arms m, carrying bearings for said spiral-faced roller, and a treadle or lever controlling the movement of said arms, all substantially asset forth.

2. The combination of an endless band and feed-rollers with a weighted lever, t, carrying zo a scraper.

3. The combination of the endless revolving band of a skin or leather treating machine JOHN MEREDITH JONES;
