SPECIFICATION forming part of Letters PatentNo. 601,133,-dated March 22, 1898. Application filed January 9, 1897. Serial No. 618,583. (No model.)

To a/ZZ whom it may concern,.-

Be it known that I, OTTO F. FEIX, a citizen of the United States, residing at Gloversville, in the county of Fulton and State of New York, have invented certain new and useful Improvements in Abrasive Appliances; and I do hereby declare the following to vbe a full, clear, and exact description of the invention, such as will enable others skilled in the artto which it appertains to make and use the same.

This invention relates to improvements in leather-working machinery, and has more particular relation t'o machines-forgdressing the surfaces of skins to remove the grain therefrom or to remove in a dry or wet condition ythe excess of flesh on the ieshy side of the skin to make the leather of a uniform thickness and smoothness.

The invention consists of certain novel conla perspective view of the machine embodying my invention. Fig. 2' represents a vertical section through the same, and Fig. 3 represents an enlarged detail top plan view of the straightening-roller.

A in the drawings-represents the frame of my improved machine; B, the abrasive roller; C, the feeding pressure -rol1er, and Dl the scraping-roller. Said frame A may be of any desired material and comprises a .base a and rigid spaced standardsv a', the latter being formed at their upper ends lwith journalboxes a2 for the reception of a transverse shaft a3, upon which the abrasive roller B is mounted. Said roller B may be of any desired construction and is provided upon its outer surface with any suitable abrasive sub- The said shaft a3 is provided at each end with a belt-wheel b and b', respectively. The said wheel b is connected to the source of power by asuitable belt b2. A supportingtable E is mounted on the frame A and is provided with a false hinged top e, normally held up by coil-springs e', inserted under the forward free end of the'same. Said top e is provided at each end with hinges e3, which are secured to the uprights of the table portion e, so that said top may rise and fall, as hereinafter described. This table, when in its lifted position, is adapted to contact with the straightening-roller D, which is journaled in suitable standards upon the frame A. This roller Dis constructed of rubber and is provided upon its periphery with oppositely-eX- `tending spiral grooves d d, which start from its middle and extend to its ends, the grooves forming said spirals passing about said roller in opposite directions. The office of this roller is to catch the skin or leather and straighten the same, smoothing out all creases or bumps therein. The ,said roller receives motion through the medium of the belt-wheel d', mounted upon its shaft and connected to the belt-wheel Z9 by a straight belt d2.

4It will be observed from the 'foregoing description that when the table e is forced downward the leather may be readily slipped under the roller D and forced into contact with the same by the release of said table. The feeding pressure-roller C may be of any desired material and is provided about its periphery with a vrubber facing c, adapted to grip the skin and hold it during the polishing operation. This roller C is journaled in supports c', which are hinged at their lower ends to the frame A, as at c2. Said standards c' are connected together, so that they will be caused to move in unisonby a cross-bar c3, under which is mounted a plurality of spiral springsl c4. v`Said springs c4 tend to normally tip the standards upon their hinges, and thus force the roller C into contact with the roller B.

When it is desired to separate the roller C from the roller B to enable the skin to be passed therethrough without being polished orV cut, Vthe foot is placed upon the cross-bar c3, whereby the same is depressed,thus causing the roller O to swing away from the roller B. Each of the standards a is provided with a laterally-extending arm 0,5, provided at its outer end with an adj usting-bolt a6, adapted to contact with its respective standard c. By means of said bolt a6 the movement of said roller O toward the roller B may be regulated at will. The shaft of said roller C is provided with a belt-wheel c5, connected by a belt c6 to the source of power. The roller B is so connected with the engine that it makes a maximum revolution of two thousand per minute, while the roller Chas a maxi- IOO mum revolution of only two hundred per minute. It will be observed from this thatl the skin passing over the roller C will be held iirmly to the same and the roller B, which is moving at a greater speed, will cut or grind all of the irregularities on the grain from the surface of the skin and leave it smooth and polished ready for cutting for the manufacture of gloves and other dressed leather articles.

By means of the spirally-grooved roller B the skin passing under the same is eectively straightened and all wrinkles removed from the same, commencing from the center and extending outward, so that said skins are fed between the rollers C and B in such manner that there will be no danger of them creasing between said rollers and thus being cut through by the abrasive roller. It will further be observed that when it is desired to insert the skin between the rollers C and D the simple pressure of the foot upon the bar c3 will cause said rollers to separate to permit this action. It also becomes necessary at times to instantly stop the action of the abrasive roller, and to eiect this result a similar depression ot' the cross-bar c3 by the foot is made.

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

1. In a leather-dressing machine, the combination with an abrasive roller, of a pressureroller contacting with the same, a straightening-roller having spiral grooves formed in its periphery, a spring-pressed table mounted under the straightening-roller and adapted to press the leather up against the same so as to feed it forward and hinges connecting one end of said table to the frame of themachine, substantially as described.

2. In a leather-dressing machine, the combination with a base, of an abrasive roller, a feeding-roller, two connected standards yhinged upon the base and provided at their upper ends with journal-boxes, a pressureroller journaled in said journal-boxes and springs mounted under the free ends of the standards for tipping the same to bring the pressure-roller in contact with the abrasive roller, substantially as described.

3. In a leather-dressing machine, the combination with a base, an abrasive roller, a feeding-roller, standards hinged upon the base, a pressure-roller j ournaled in the upper end of said standard, springs mounted under the free ends of said standards for tipping them to bring the pressure-roller in contact with the abrasive roller, and adjustable stops for limiting the movement of said standards7 substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
