FUR-PLUCKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 534,787, dated February 26, 1 B95.

Application filed August '7, 1894.

To all whom t may concern.-

Be it known that I, IsIDoR DRESDNER, of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Fur-Plucking Machines; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this speciiication.

In Letters Patent of the United States granted to me March 7, 1893, and numbered 493,017, is represented an improved machine for plucking the long hairs from skins, in the use of which machines the long hairs of the skins to be plucked are presented to the grasp of the plucking rollers through the teeth of a comb, the elastic roller being also given a vertical reciprocation. The machine shown in this patent is exceedingly welll adapted for operation upon certain kinds of skins but it has been found that for operation upon certain other kinds of skins the hairs are admitted into the grasp of the plucking rollers and also that insome cases the hairs are more or less affected by the current of air produced by the repeated rotation of the bladed roller. After repeated experiments I have found that the difficulties mentioned, in the treatment of the class of skins referred to may be overcome by substituting for the comb of the former machine a continuous blade the edge of which stands in close proximity to theelastic roller while the latter rotates upon fixed bearings instead of reciprocating bearings.

In the operation of the improved machine the hairs of the skin operated upon are protected from the currents of air created by the bladed roller and coming into contact with the surface of the elastic roller and are drawn by it over the continuous edge of the interposed blade into the grasp of the two rollers.

In addition to the changes above referred to I have also improved the present machine in various details of construction, all of which will be fully set forth hereinafter and pointed ont in the claims.

In the accompanying drawings: Figure l is a plan view of the improved machine, the

main shaft and driving pulley being broken off to save space. Fig. 2 is a side view of the saine. Fig is a section on the line -x of Fig. l. Fig. 4 is a detail view inlongitudinal section through the bladed roller. Fig. 5 is a detail view in perspective of one of the plates of the bladed roller; and Fig. 6 is a de- 'ta'il view in perspective of one of the notched collars by which the plates are secured in position.

In suitable standards A, A, A', which are erected upon a bed-plate B, the main shaft C has bearings in which it may rotate freely. Upon the extremity of the shaft O may be secured the pulley D by which the shaft is driven and a small balance-wheel D. The shaft C also supports or forms in part the bladed roller of the two plucking rollers, it being .adapted to receive, between the standards A, A, the blades one of whichis shown at E in. Figs. 3, 4 and 5. The shaft is formed with longitudinal grooves c in any convenient number and each blade E is adapted to fit easily in one of these grooves, each blade having lugs e, e, at its ends.

Two collars F, F, are slipped upon the shaft C, each collar being provided upon its inner end'with a notch f and being adapted to be secured in position upon the shaft by a set screw f. The collars F, F, bear against the standards A, A, and therefore cannot be shifted longitudinally upon the shaft to permit the introduction of a blade E, but by rotating the two collars to bring their notches f,f, into alignment with one of the longitudinal grooves c the blade maybe introduced into such groove and then held firmly in po` sition by a further rotation of the collars upon the shaft.

The roller G which co-operates with the bladed roller is preferably composed of a rubber or other elastic body mounted upon a spindle g. The latter has bearings in arms H, H, which are secured respectively to the members of a two-part sleeve h, h. This sleeve is mounted upon a shaft I which is supported in exactness to the standards A, A, and the two parts are coupled by a tongue and slot connection, as indicated clearly in Fig. l, so that there can be no rotation of one part with respect to the other. Each part is also provided with a set-screw h2 by which it can be secured lin position on, the shaft I. By this construction either part h or 71. can be re- IOO leased by loosening the setscrew h2 and `slipped longitudinally upon a shaft Ito permit the removal of the roller G without disturbing the axial adjustment which has been found advantageous. To the extremity of the shaft I is fixed an arm J which has near its outer end a transverse slotj. A screw-stud K is fixed in the standard A in position to enter the slotj and is provided with a nut and washer 7c. This arrangement permits an easy adjustment of the roller G toward or from the bladed roller. The arm J is preferably split, as represented in Figs. 1 and 2, and is secured to the shaft I by a bolt L and nut Z. The bed-plate B also supports a slotted standard M between the two parts of which is placed the slotted stem N which supports a plate O. A bolt n passes through the two parts of. the slotted standard IWI and through the slot of the stem N and is provided with a nut n whereby the stem N may be clamped between the two parts of the slotted standard M and the plate O thereby holding it in adjusted position. The plate O has a continuous upper edge 0 and is preferably imperforate and bent substantially as represented in Figs. 2 and 3. It stands in close proximity to the bladed roller with its continuous upper edge, near the periphery of the roller G and in such position that the hairs which project from the skin under treatment across the edge of the blade and against the periphery of the roller are drawn down by saidV roller so that they may be seized between the same and the blades of the other roller.

The skin under treatment is drawn over the supporting rod P by the hands of the operator and the rod is adjustably supported by a frame R so that the skin can be pushed toward the plucking rollers by the pressure against the cross-bar R or removed therefrom by springs R2 in the usual manner. The plate O supports the skin to some extent against the pull of the pluclzing rollers, substantially as does the comb which is replaced, but it not only protects the hairs from the current of air produced by the bladed roller as the comb could not but it also presents the long hairs to the plucking rollers in a manner altogether different from that which they would be presented through a comb and thereby enables the machine to be used more effectively upon certain classes of skins and Without the reciprocation of the elastic roller.

The operation of machines of this character being already well understood it need not bey further explained herein.

I claim as my inventionl. In a fur plucking machine, the combination of a bladed roller, an elastic roller mounted in fixed bearings parallel with the bladed roller and in proximity thereto, and an imperforate plate with a continuous upper edge supported in front of the bladed roller with its continuous upper edge in proximity to the elastic roller, a slotted stem supporting said blade, a slotted standard in which said stem may be clamped and a clamping screw, substantially as shown and described.

2. In a fur plucking machine, the combination with a bladed roller,l of a shaft supported in parallelism therewith, a two-part sleeve mounted on said shaft, the two parts of said sleeve being coupled `end to end by a tongue and slot connection,means to secure the parts of said sleeve in position upon said shaft, arms carried respectively by the parts of said sleeve, and a roller mounted in said arms to cooperate with said bladed roller, substantially as shown and described.

3. In a fur plucking machine, the combination of a bed-plate, standards erected thereon, a bladed roller mounted in said standards, a shaft mounted in said standards in parallelism with said roller, arms secured to said shaft, a roller supported by said arms to cooperate with said bladed roller, the third arm fixed to said shaft having near its upper end a transverse slot and a screw-stud passing through said slot and fixed in the adjacent standard, whereby the second roller may be adjusted toward or from the bladed roller, substantially as shown and described.

4. In a fur plucking machine, the combination with a shaft having a series of longitudinal grooves, of collars slipped on said shaft and having in their proximate ends notches which may be brought into alignment With said grooves, blades adapted to enter said grooves through said slots and having lugs at their ends and means to secure said collars in position, substantially as shown and described.

In testimony whereof I have signed my name to this specilication in the presence of two subscribing witnesses.
