Application filed April 20, 1903. Serial No. 153 ,443. (No model.)

To all whom it mayoria/cern: v

Be it known that I, EMIL SCHROEDER, a citizen of the United States, and a resident of the city of NewYork, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Fleshing and Shaving Machine forRaw and Dressed Furs. or Skins, ofwhich the following is a full, clear, and exact description. The object ofthe invention is to provide a new and improved fleshing and shaving machine for quickly and accurately removing the surplus flesh from the under or iiesh side of raw furs or skins and for paringor shaving the under or iiesh side of dressed furs or skins to reduce the same to a desired uniform thickness.

f The invention consists of. novel features and parts and combinations of the same, as

Fig. 3 is an enlarged cross-section of a modified form ofthe disk cutter, having an overlaid knife-edge similar to a Currier knife edge. Fig. 4 is a frontelevation of the improvement as arranged with a traveling endless-band cutter. Fig. 5 is a side elevation of the same. Fig. 6 is an enlarged sectional side elevation of part of the driven wheel andthe endless-band cutter. Fig. 7 is a diagrammatic plan view of the cutter and thegage,

for the endlessfband cutter.

In removing the iesh and other superfluous matter from the under or iiesh side of raw fur or skin it has been the practice to first soak the skin, .then to straighten it over -the dull edge of the fleshingknife, and to the inventionV to the desired'thinness. Now both operations are not only very tedious andV slow, but require considerable skilled labor.

With4 my improvement, presently to be described in detail, it is possible for an unskilled workman to properly remove the surplus flesh from the raw furs and skins for accurately paring or shaving the dressed furs .or skinsto a desired uniform thinness in a comparatively short time and without danger of injuring the fur or skin.

On a suitably-constructed standard or other support A is journaled a shaft B, carrying a pulley C, connected by belt with other machinery for imparting a high-speed rotary motion tothe said shaft B. On the latter is secured the hub D of a diskcutter D, arranged between the spaced members E E2 of a stretcher gage or guard E, carried vby the support A, the said members E E2 consisting each of a fixed section E3 and a hinged section E4, connected by a vertically-disposed hinge E5 to thefixed section E3.

The hinged sections'E1 of the two members VE' and E2 can be swung toward and Vfrom each other at the front end of the machine, and for this purpose the said sections E4 are connected'with each other at the top and bottom 'and outside of the peripheral cutting edge of thevcutter D by left and right hand screwrodsF, so that on turning the latter in one :direction the hinged members E and E2 swing to the nature of the fur or skin under treatment.

The operating edge's E6 of the gage E are in the form of plates transversely adjustable on the hinged sections E4, and the terminals'of the said edges are concentric with the periphery of the cutter D, the annular cutting edge of which extends or projects beyond the said terminals, as plainly indicated in Figs. l and 2. Now the distance the cutter cutting edge projects beyond the terminals of the edges E6 can be regulated by adjusting the edges transversely on the hinged sections E4 for regulating the depth of the cut of cutter on the furs or skins.

For the purpose mentioned each hinged section E4 is provided with transverse slots E7, through which extend the buttons E8, secured on the corresponding edge E5. One of the buttons E8 (preferably the middle one) is in the form of a nut, in which screws a screwrod G, mounted to turn in a bearing E, held on the hinged section E4. Now by turningthe screw-rod G the edge E6 is moved outward or inward, according to the direction in which the screw-rod G is turned, to allow of adjusting the edges EG to bring their terminals in proper relations to the peripheral cutting edge of the cutter D for a shallower or deeper cut of the cutter on the fur or skin.

On the support. A, below the cutter D and its stretcher-gage E, is arranged a stretcherknife H, over which the furor skin is pulled to straighten the same previous to moving the fur or skin sidewise over the terminals of the edges E6 and the interposed cutting edge of the cutter D, it being understood that for both operations the operator is preferably seated in rear of the machine to be in position for conveniently pulling the flesh side of the furs tightly over the stretcher-knife II to straighten the skin and for con veniently drawing the esh side of the fur or skin firmly and straight over the gage E and the cutting edge of the cutter.

The operation is as follows: In preparing the raw furs or skins for the machine the under or flesh side is soaked and laid in wet sawdust for a certain length of time-that is, until the skin is soft and pliable-and then the flesh side of the fur is pulled tightlyover the stretcher-knife H until the skin is straight and even, and then the operator slowly draws the skin sidewise, preferably from the left to the right, over the gage edges E6 against the cutting edge of the rotary disk or band cutter, so that the cutting edge cuts the surplus flesh from the under side of the fur or skin to a depth corresponding to the distance the said cutting edge of the cutter projects beyond the terminals of the gage edges E6. For fleshing large skins the edges E6 are preferably set relative to the cutter, as shown in Fig. 8, to move the skin in an oblique or angular direction over the cutter, and for small skins I prefer the use of the curry-knife cutter shown in Figs. 3 and 4 and arrange the edges EG alike ou the sides of, the cutter, as indicated in Fig. 7, to allow of drawing the fur approximately at right angles over the cutter for the purpose mentioned. Now it is evident that by drawing the straightened flesh side of the fur or skin across the machine in the direction described the flesh surface of the fur or skin is in contact simultaneously with the gage-terminals-that is, at two places located on opposite sides of the cut made by the cutting edge of the cutterand hence the latter cannot cut deeper into the skin than the distance to which the cutting edge of the cutter projects beyond the terminals of the gage edges E, and an unskilled workman is therefore not liable to injure the fur or skin by causing too deep or irregular cuts. After the raw skin or fur is freed of the liesh it is dressed in the usual manner, and then the above-described operation is repeated for paring or shaving the under side of the fur or skin to a uniform thinness, and this operation is preferably carried on over the cutter and gage set as shown in Fig. 7.

I do not limit myself to the particular form of cutter above shown and described, as the same may be varied. For instance, as shown in Figs. 4: and 5, the cutter is in the form of an endless band D2, traveling under an idler- Wheel I and over a driven wheel J, connected with suitable machinery for rotating the driven wheel,and the said endless band passed between the edges K K2 of a stretcher gage or guard K, attached to the support A and approximately similar to the stretcher-gage above described, with the exception that the terminals of the edges K K2 are straight and vertically disposed, while the terminals of the edges E6 are segmental, as previously explained. The cutting edge of the traveling endless band D2 projects, however, a distance beyond the terminals ofthe said edges K K2, the same as above described in reference to the cutterD and the terminals of the edges E.

In order to hold the cutter D2 against lateral displacement, it is provided at its inner face a distance from the cutting edge with an annular shoulder D3, engaging corresponding annular grooves in the wheels I and J.

In using the modified form of machine the operator proceeds in the same manner as above described relative to the machine shown in Figs. 1 and 2, so that further description thereof is not deemed necessary.

Having thus described my invention, .I claim as new and desire to secure by Letters Patentl.
