SPECIFICATION forming part efl Letters Patent No. 623,176, dated Api-i1 1s, 1899.

Application filed October i, 1898.

To aZZ whom it may concern:

Be it known that I, EDWARD S. PARKS, residing at Danbury, in the county of Fairfield and State of Connecticut, have invented a 5 new and useful Shoddy-Making Machine, of

which the followingis a specification.

This invention relates to a shoddy-making machine, the object being to provide an eX- ceedingly cheap, simple, and efficient means 1o for tearing or pulling to pieces all kinds of knitted or woven fabrics, Whether of cotton, wool, or fur, and converting the same into shoddy.

Another object of the invention is to provide a machine which shall be exceedingly quick and efficient in operation, thereby overcoming the objections to the machines now in use for these purposes.

Another object is to provide amachine in 2:; which all clogging of material is avoided.

The invention consists in providing a novel construction of feed mechanism whereby the material to be shredded or torn is fed evenly to the tearing-disks and all danger of the maz 5 terial clogging avoided.

The invention consists also in certain details of construction and novelties of combination, all of which will be fully described hereinafter and pointed out in the claims.

In the drawings forming a part of this specification, Figure lis a view showing a machine constructed in accordance with myinvention. Fig.v2 is a sectional view of the machine and operating parts. Fig. 3 is a vertical section on the line 3 Seof Fig. 2. Fig. 4 is a horizontal section on the line et 4 of Fig. 2. Fig. 5 is a detail view of the disk through which the material is fed.

In carrying out my invention l employ a 4o suitable base A, to which is attached a case B, within which revolve the disks C and C', said disks being rigidly mounted upon the shafts D and D, respectively, said shafts being journaled in suitable hangers E and rotated in opposite directions by means of the band-pulleys F, mounted upon the shafts, the outer ends of said shafts being provided with balance-wheels G, as most clearly shown, the purpose of which is to counterbalance the 5o disks C and C, carried upon the inner1 ends of the shafts D and D, respectively.

Serial No. 692,716. (No model.)

The disk C has a ring C2 bolted to the inner face. thereof, said ring having the teeth C3 upon the inner face thereof, said teeth being constructed of steel or other suitable metal, and the ring, though preferably constructed of wood, may be made of any desirable material.

The disk C has a central circular opening, and the central portion of the disk C4 is set 6o in some distance beyond the body of the disk C', and, in fact, the portion C/ is set in beyond the central line of the case, as most clearly shown in Fig. 2, said central portion. being connected with the body portion C by means of the arms C5.

The shaft D is connected to the central portion C4, and inasmuch as this central portion is connected to the disk C/ the said disk will of course be rotated in a direction opposite 7o to the disk C. The portion C is also provided with a ring C2, having the teeth C3, which ring and teeth are constructed and arranged exactly the same as those upon the opposing disk.

The case B is formed with a central opening B, opposite the central opening of the disk C', and arranged in saidA opening is an inwardly-projecting ring H, which projects inwardly nearly to the central line of the 8o case, and at the upper portion of the said opening B/ isarranged the feed-hopper H', in which the material to be torn is fed, said material being drawn inward by means of the arms C:7 and forced between the teeth of 85 the disks by centrifugal force.

The arms C5 clear themselves by centrifugal force of the greater portion of the material; but to prevent any possibility of the material clogging upon the said arms I pro- 9o vide a scraper-arm I, which projects inwardly from the ring H and engages the inner faces of the arms C5 as they revolve about the scraper-arms, thereby clearing away any material which might by any possibility remain 95 upon the said arms C5.

The central portion C4, projecting inwardly beyond the central line of the machine, compels all of the material fed through the hopper to be instantly thrown between the teethroo disks by centrifugal action, and as the said.

disks are rapidly revolving in opposite directions it is clear that all of the material so thrown between them will be quickly and thoroughly torn or shredded.

The operation of my device is exceedingly simple and is believed to be clear to every one skilled in the art to which it pertains. The shafts D and D are revolved in opposite directions, rotating the disks C and C in opy posite directions, which disks are provided with tearing-teeth upon their opposing faces. The material fed through the hopper H is led directly to the center of the machine, and

the rapid rotation of the disk C causes the material to be thrown between the tearingdisks by centrifugal action, and the material Ais thus quickly and easily reduced to the I claim as new, and Ydesire to secure by Letters Patent, is-

l. In a shoddy-making machine, a pair of oppositely-rotating disks provided with tearing-teeth upon their opposing. faces, one of said disks having a central opening and provided with arms for forcing the material be tween the tearing-disks, and a seraperarm for clearing said arms of any accumulated mated rial, substantially as shown and described.

2. In a machine of the kind described, the combination with a case, of the oppositely-rotating toothed disks arranged wi thin the case, one of said disks having a central opening and provided with distributing-arms, the case having an opening opposite the opening of the disk and provided with an inwardly-projecting ring, the feed-hopper and scraper-arm, together with means for rotating the disks` in opposite directions, substantially as shown `and described.
