SCOURlNG-ROLL.

SPECIFICATION forming part of Letters Patent No. 462,886, dated November 10, 1891.

Application filed March 2'7, 1891- Serial No. 386,619. (No model.)

T0 at whom it may concern:

Be it known that I, Gnonon E. WARREN, a citizen of the United States, and a resident of Exeter, in the county of Rockingham and State of New Hampshire, have invented new and useful Improvements in Scouring-Rolls, of which the following, taken in connection with the accompanying drawings, is a specification.

This invention relates to improvements in scouring-rolls particularly designed for the purpose of securing or abrading the bottoms of soles and heels on boots and shoes, although it is equally useful for other scouring or abrading purposes.

The invention is carried out as follows, ref erence being had to the accompanying drawings, wherein- Figure 1 represents a side elevation of the improved scouring-roll, showing the hinged segmental portion swung open for detaching and attaching the abrading medium. Fig. '2 represents a cross-section on the line X X in Fig. 1, showing the hinged segment locked in position when the scouring-roll is in use; and Fig. 3 represents a central longitudinal section on the line Y Y in Fig. 2, showing the rollshaft, its pulley and bearings in elevation.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

In the drawings, A represents a bracket or standard, of any desired size and shape, having bearings a a, in which the scouring-roll shaft 13 is journaled, said shaft having attached to it a pulley B, to which a rotary motion is conveyed by means of belt-power, as is usual in machines of this kind.

The improved scouring roll is composed of two parts preferably made of wood-namely, a main portion C and a segmental smaller por tion (1, which together form a cylindrical roll, as shown in the drawings. The parts 0 and O are hinged together at c, as shown in Figs. 1 and i. The part C is preferably secured to a metal flange D, having a hub or sleeve (Z mounted on the shaft B in any manner suitable for the conditions required.

I) is a shoulder or projection on the shaft B, against which the flange D is held, as shown in Figs. 1 and 3.

E is an elastic cushion surrounding the roll portions C C, it being divided at the meet ing edge 0'', as shown in Fig. 2, said cushion being preferably made of felt or similar elastic or compressible material.

F is the abrasive covering, which is preferably composed of a sheet or strip of said paper, emery-paper, or the like, which incloses the cushion E and is lapped over the meeting edges C of the roll parts (1 and C, as shown in Fig. 2.

The improved locking device for securing the roll parts 0 and C together and to the shaft B is constructed as follows: It consists of a disk G, adapted to turn upon and also to move longitudinally along the shaft B and to be locked in position on the latter by means of a pin B", secured to the said shaft and projecting through a bayonet-slot g in the hub of the locking-disk G, as shown in the drawings. The disk G is normally forced against the roll 0 C by the influence of aspring H, surrounding the shaft B between the outer end of the hub of the disk G and a collar or projection B secured to the outer end of the shaft B, as shown in Figs. 1 and 3.

G is an eccentric inclined or cam-shaped slot-hole in the locking-disk G, adapted to receive a pin C on the segment 0 when the said disk is liberated and moved toward the roll 0 O in locking the roll and disk together.

The operation of the device is as follows: If it is desired to remove the abrasive covering and replace it with another, the disk G is moved away from the roll and turned sufficiently around the shaft to cause the pin B to enter the lateral portion of the bayonetslot when it will be locked and held in position by the influence of the spring H, as shown in Fig. 1. The segment 0 may now be swung outward, as shown in Fig. 1, to permit the removal of the worn-out abrasive covering and wrapping a new one in its place, after which the segment 0 is closed by swinging it to the position shown in Fig. 2. The disk G is then turned slightly on the shaft B, so as to cause the pin B to enter the longitudiual portion of the bayonetslot g, causing the disk G to be forced toward the roll 0 C and causing the pin 0 011 the segment 0 to enter the slot-hole G, as shown in Fig. 3. By

turning the roll 0 O slightly in the direction of the arrow shown in Fig. 2 the roll parts 0 C will be clamped together and to the disk G, which is secured to the shaft, and also causing the turned-in edges of the abrasive covering F to be clamped between the adjoining edges of the roll parts 0 C, all as shown in Figs. 2 and 3.

To disengage the rollfrom the locking-disk the roll is turned slightly in an opposite direction and the locking-disk moved to the position shown in Fig. 1.

For *narrow rolls a single locking-disk is sufficient, but for longer rolls I may prefer to use two such locking-disks, one at each end of the roll, without departing from the essence of my invention.

Having thus fully described the nature, construction, and operation of my invention, I wish to secure by Letters Patent and claim- 1. The combination, with ashaft, of a scouring-roll composed of two sections, one of which is hung on the shaft and the other hinged to the former and provided with alaterally-pro jecting locking-pin, a longitudinally-movable and rotating locking-disk having an ecing-disk longitudinally movable on the shaft, W

having an eccentric groove or slot to receive the locking-pin on the hinged roll-section and provided with a hub havinga bayonet-slot to receive the projection on the shaft, substantially as described.

In testimony whereof I have signed my nameto this specification, in the presence of February, A. D. 1891. v
