MACHINE FOR CUTTING UP PELTS.

SPECIFICATION forming part of Letters Patent No. 257,314, dated May 2, 1-882.

Application filed December 27, 1881. (No model.)

To all whom it may concern:

Be it known that we, THOMAS GIBSON and EDWARD ARMSTRONG, of Brooklyn, in the county of Kings and State of New York, have 5 invented a new and useful Improvement in Machines for Cutting up Felts; and the following is declared to be a description of the same.

' Pelts or skins of animals with the furor hair on have for years been used commercially-the fur or hair for felting purposes and the skin for glue; but the separation of these parts has not heretofore been accomplished in the most desirable manner. The machine heretofore 1 5 employed for cutting up pelts contained rotary cutters having knives that are screwed upon the outer surfaces of heads fastened upon a shaft. It has, however, been very difficult to make the cylinder with these knives perfectly 2o balanced so as to run true and without vibrating the machine under the'high rate of speed employed. Besides this, the fur or hair (after its separation from the skin) has been delivered near the place where the pelt is fed in; hence there is not room for the workmen to work with advantage.

Our improved machine is designed to 0bviate preexisting difficulties. WVe employ a rotary cutter that is constructed so as to be 0 perfectly balanced, and the fur or hair is taken away by a belt to a point of delivery that is at some distance from the place where the pelts are fed in, and the strips of skin are delivered at the side of the machine, out of the 5 way of the attendants. \Ve also use a fur or dust box, into which the fine pieces of fur or hair from the skins are delivered as thrown off by the revolving cutters.

In the drawings, Figure l is a side elevation 40 of the machine complete. Fig. 2 is a longitudinal section of the machine. Fig. 3 .is a front elevation of the machine with the armrest removed, and Fig. 4 is a plan view of the cutters and forward part of the machine with 4 5 the dust-cover of the cutters removed.

Power is communicated to the machine bythe belt a and fast and loose pulleys b. 1) upon the shaft 0; and d is a belt-shifter of the usual form for starting and stopping the machine,

and said belt-shifter is moved by the foot of the operator upon the lever d; The wheels e 0 upon the shaft 0 and the belts ff give mo tion to the pulleys g g upon the cutter-shaft h.

The shaft h and cutter-head are of one piece of metal. The cutter-head is made as a cylinder. Its exterior surface is turned off true. The journals at the ends are also turned true. The cylinder and shaft are supported on centers in a shaping-machine or planer, and grooves are planed in such cylinder, as seen at 6 Five of these grooves are represented, and each groove is inclined to the axis of the cutterhead, as seen in Fig. 2, so as to be adapted to the reception of the twisted cutter i, which acts with a shearing out against the standing shear k. We have represented fiveof these cutters i secured to the bodyt' by tap-bolts, and said cutters are slotted for the bolts to pass through them, so as to be capable of being brought forward toward the standing cutter-bar k as they wear away, and they are easily removed or replaced as occasion may require. The cutters 'i and cutter-bar 70 extend across between the side frames, A, and there is a cover or dust-cap, l, over the cutters, 7 5 and said cover is hinged at 1 to the frame of the machine, behind the cutters, and the arms 2 extend forward from the dust-cap, and are connected at 3 by a cross-bar, which serves the double purpose of an arm-rest and lever to keep the cover down or lift it up, as necessary. These arms also serve to apply pressare to the feed-rollers.

There are small grooved'ieeding-rollers m n, which areclose to the standing cutter is, and nip the pelt as it is fed in head first between the rollers and carried forward to the shear k and revolving cutters t", and these cutters, revolving at a high rate of speed, cut up the hide or skin into small shreds and cut off the 0 hairs near their roots, and hence the hairs will be left against the outer surface of the stand in g cutter k, and will not be carried away by the revolving cutters i, and the accumulation of hairs against this standing shear will cause 5 such hairs to pass down the incline o in the form of a fleece corresponding in size and shape to the skin, or nearly so, as the hairs mat and hold together. The shreds of hide out up by the cutters-t are thrown down into I00 the receptacle and upon the endless belt a, which belt carries them off laterally, and they fall over the end roller down the incline s to the floor or into a receptacle. The fleece of fur or hair upon the incline 0 ceases to be held up by the skin as soon as the last of the pelt has been out up by the cutters i, and said fleece then slides down said incline o and off upon the incline t, by which its direction is changed, and it is delivered upon the endless belt u, which carries it forward to the roller 25, where the fur or hair is taken by a roller, 1;, which is revolving in the same direction as the roller 4, and prevents the mass of fur or hair adhering to the belt a. Said fur or hair then slides down the incline w upon a table, at which the operatives sort over the mass of fur or hair, separating the inferior or refuse portions from the most valuable parts, as usual in preparing for or hair for felting purposes.

The mass of fur or hair as separated from the hide is upon the incline 0, with the outer side uppermost, or, in other words, with the points of the fur visible. In its passage from the incline 0 to the incline t the mass of fur or hair slides downwardly and passes to the incline t, the points of the hair now being downwardly, and this position is maintained during the passage to the hands of the operator. The refuse from the cutters i, which is in the form of dust and fine fur or hair, is carried into the box 1) of the machine, and then through the opening 5 into the receptacle 1), where it is allowed to settle. The speed of the cutters sets up a current of air through the receptacles 11 and p and dust-box, the exit for which air is through the wire-gauze gratings at 6, and these gratings are removable, so that the accumulation of material in the dust box or receptacle p can be taken out at pleasure.

The wheels 7 and 8 are upon the same shaft, and are secured in a bearing upon the frame A of the machine. The wheel 7 is belted to the wheel 9 on the driving-shaft c of the machine, and the wheel 8 is belted to the wheel 10, which wheel has a bearing on the top of the frame of the machine. Upon the same shaft as the wheel 10 there is a toothed wheel, 11, gearing into a toothed wheel, 12, which is upon the shaft of the feedingroller n, and the bearings of these shafts are upon the top of the frame A of the machine.

The feeding-roller at has its bearing, by preference, in the frame of the cover Z, and when the cover is raised the roller m is also raised, thereby giving easier access to the cutters and cutter-bar, and these feeding-rollers in and n are connected and driven by toothed wheels 13 and lat upon their respective axes. (See Figs. 3 and 4.)

The endless belt 1' is around the rollers 15 16, and is driven from a wheel, 17, upon the axis of roller 15, which is belted to a wheel, 18, upon the driving-shaft c of the machine. The roller 16 is supported by a frame, as shown,

and said belt r can be tightened as itbecomcs loose by the adjustable screw and nut 19. The wheels 20 and 21 are upon the same shaft or spindle, and secured, as shown in Fig. 1, to the side of the frame A of the machine. The wheel 20 is belted to a wheel, 22, upon the driving-shaft c, and the wheel 21 is cross-belted to a wheel, 23, which is upon the same shaft as the roller 24., which carries one end of the belt a, and motion is communicated to said belt u from the driving-shaft c by means of these belts and wheels 22, 20, 21, and 23.

The endless belt a is driven by wheel 23 and roller 24, and it passes around this roller 24, and also around the roller 25, which is .supported by the brackets 26. The brackets 26 are supported by the frame Aof the machine, and there are adjustable rods 27 in the ends of these brackets, acted upon by nuts in recesses in the brackets, as shown, and these rods carry the bearings that support the roller 25, so as to tighten the belt a if it becomes loose.

The roller 12 is driven by cog-wheels 28 from the shaft of roller 25, and it is carried by bearin gs secured to the bearingsthat support roller 25. (See Fig. 1.)

There is a brush at 29 extending across the width of the machine, and its use is to clean the revolving cutters i from any particles that may adhere to them, and there are adjustable bolts at 30, which serve to control the relation of the revolving cutters i to the cutter-bar k and keep them in contact.
