My invention relates to an apparatus for use for fleshing or scraping hides, which by reason of its simple and easy manipulation avoids the necessity of employing skilled labour.

The apparatus'is characterized essentially by the employment of a circular rotary cutting blade, which is adapted to be so regulated as to allow strips of flesh varying in thickness to be removed, according to the part ofthe hide which is being treated.

The apparatus is moreover so constructed that it is adapted to be displaced on the skin or hide in any required direction and adapted to be regulated or adjusted without the workman having to remove his hands from the framework of the machine upon which they are resting.

"\Vith these objects in view, the axle of the rotary cutter is operatedfrom a flexible shaft connected to an electric motor suspended from a runway and displaceable within the workshop. This axle is mounted in a frame adapted to oscillate in a vertical plane, the oscillations of the frame being controlled from those of two cams operated by the fingers of the workman whose hands are applied to the neighbouring handles, permit ting of the displacement of the socket.

This tool holder may also be adjusted longitudin'ally in such a manner as to allow of regulating the distance between the active part of the cutting bladeand the front part of the frame which presses down upon the hide to be fleshed. Y l

. 'Moreover the apparatus may be provided with a sort of shield suitably'shaped to reject or throw off on all sides the strips of cut flesh.

In order that my invention may be better understood it will now be described with reference to the accompanying drawings which shows by way of example a simple mode of construction and an improved embodiment of a'machine for fleshing hides or. skins made according to my invention. Y

Figs. 1, 2, 3 and 4 show thefirst mode of execution. I

Fig. 1 is a side elevation partly in section.

Fig. 2 is afront elevation.

Fig. .3 is a part plan on a level with the line A, Fig. 1.

Fig. 4 shows to a smaller scale the arrangement of the unit constituting the apparatus and its driving mechanism.

Fig. 5 is a front elevation partly in section of a second mode of execution.

Fig. 6 is a plan view partly in section.

As will be seen from the drawings, according to the first mode of construction, the machine is provided with a socket or base 1 having a shoe 2 at the front intended to remove or smooth out creases in the hide or skin whilst being pushed forward during the work. The movement forward is facilitated by a slightly oblique lower surface 2 provided at the lower portion of the shoe.

The base or socket is fixed to a frame 3, between the uprights or standards of which is disposed at the rear a spindle 4 upon which are pivotally mounted lugs or extensions 5 made integral with the tool holder 6 which is, for example, cylindrical.

In the tool holder is mounted, preferably on ball bearings, a rotary spindle 7 to the end of which is attached by means of a plate 8, a circular blade 9, preferably with a lower bevelled edge 9 and brought substantially into the horizontal position by a suitable inclination givento the tool holder.

Underneath this latter is fixed a sort of shield 10 with an incurved lateral surface and extending as far as 10 and opening out on either side of the spindle, in such a manner that the strips of cut flesh are ejected or thrown away from the apparatus.

The tool holder 6 is provided with two lateral handles 11 and carries two pivotal axles 12 for cams 13 which are under the control of springs 14. attached to the tool holder on the one handand on the other hand rest on a wedge 15 displaceable in the frame in such a manner as to regulate or adjust the initial inclination of the system when-at rest, an inclination which as has already been seen, in which the bevel of the blade is substantially horizontal, with the plane of the upper portion of the blade directed under the rear edge of the shoe 2.

The earns 13 are provided with hook pieces the positionl3 to another position 18 determining the various inclinations for 16, into which the workman hooks' lllS forefinger, which allows him, whilst still holding the handles 11, to oscillate the cams from thus the blade between'the positions 9 and 9 and thus allowing, during working, the thickness 7 y of the layer of flesh being removed to be varied according to of the hide to be treated. {The rotary spindle of the region of the hide which is being treated, the back, head, feet, udder'or the like. f l i .1, .As regards the initial regulation by means of the wedges I5'thisiseffected-according to the type .of work to be done and the nature the machine iscoupled bv a flexible shaft 17 toa small electric 'motor l8 (Fig; 4) provided with a reverser, which imparts to it a movement of rotation of suitable speed. motor may be suspended on a loop 19 hooked to agroovepul-ley 20 running on a suitable-rail, cable or profile track," This arrangfiment. allows the motor the apparatus in direction, without-interfer ng I to follow the movements of a longitudinal a with the .pliability of the flexible shaft couslin I: I i "i j l The: skin or hide to be treated is stretched outandmaintained on a horizontal table 22, covered with a sheet of zinc 23. The work m-an takes hold of the apparatus by the handles and pushes itv in .a forward direction over. the skin. The apparatus works like a plane and carriesawayshreds orstrips of flesh adhering to the skin.

' The workman then brings the apparatus ragainto the: rear: and again pushes it. forward to remove a' the w-hole surface. When he comes to a part which is-mo-re fleshy, as for instance thehead, the feetfor. thendder, he operates upon' the cams with the forefinger in such away as to removea much greater thickness of flesh.

The .unit mechanism may with advantage becompleted or associated with means for sharpening the cuttingblade duringthedisplacementorwhen changing thelhide. For

V thispurpose one or two fgIlIldStOIlGS QaLmay I be ,providedasay one hard and one soft, 150

which are sprayed. with. water andwhich extend to thelevel ofthe workbench, so that it isyonly necessary to push the apparatus over these stonesv to obtain the required sharpening, the blade and the stone, turning together.

In the second mode of'eXecution shown in Figs-5, thecircularcutting blade 9 is bevelled atits upper edge.

The directi on in which it works being determinedby the bisector of the angle of the bevelwhich must. form an angle of about-10 with the surface of the hide,

this arrangement allowing a very wide cut with the least possible inclination. a The socket or base 2 is provided at between the standards with a wide hollow to prevent the-heaping up of flesh between the freshstrip of flesh andjso on, over shield 10 and the base, it'is also provided at 26 (Fig. 6) with a discharge opening. The strips of flesh will thus be easily evacuated and will not impede the movement of the tool holder. The, latter having for example the shape of a prism of square section is provided at its lower part with a cylindrical portion. The axle .7 rotates in roller bearings 27 and its vertical position is set by means of two ball abutments 28. It may thus rotate at a considerable speed.

The frame isprovided with a horizontal slot 30in-which the pivotal axle 4 of the tool holder accomplishes i a sliding motion under the action of a milled nut'31 whic'hmoves the screw 32 and the. bushing 29, through whichsaid.pivotalaxispasses.
