` ELEsHINe MACHINE.

Application filed October 27, 1921. Serial No. 510,723.

To cZZ whom it may concern:

Be it known that I, SAMUEL FRIEDMAN, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, county of Kings, and State of New York, have invented a new and Improved Fleshing Machine, of which the following is a description.

My invention relates to a machine for cut-ting the flesh from skins'and more particularly the invention relates to that type of machine in which the revolving fleshing knife has the general form of a disk. In the usual form of the machines referred to the disk is made with a cutting edge integral therewith. In thedisk being bent to form the cutting edge, obviously, the metal must be comparatively soft to permit of the bending and therefore the cutting edge does' not have the proper hardness and temper for the work and to withstand wear. i

The general object of my invention is to provide a knife having an improved cutting edge produced iny a manner to permit of the employment of high-grade steel in the manu-y facture thereof, preferably of piano wire.

A further object ofthe invention is to provide a knife for the indicated purpose in which the edge portion may be removed and discarded more economically than the grinding thereof can beeifected.`

More specifically, the invention has in view to provide a knife that initially may be effectively ground with facility and of a form that will enable the cutting edge to be preserved by the whetstone until the edge is substantially worn away.

The nature of the invention and its distinctive features and advantages will clearly appear as the description proceeds.

Reference is to be had tothe accompanying drawings forming a part of this speciicatiomit being understood that the drawings are merely illustrative of one example of the invention.

Figure 1 is a side elevation of a fleshing machine embodying my invention;

Figure 2 is an elevation at right angles to Figure 1 y y Figure 3 is a horizontal section on the line 3-3, Figure 2;

Figure 4 is a partial section on the line 4-4, Figure 2;

Figure 5 is an enlarged transverse section of the knife at the edge;

Figure 6 is a face view of the knife;

Figure 7 is an elevation of the peripheral cutting element;

Figure 8 is an edge view of said element.

In carrying out my invention in accordance withthe illustrated example the standard 11 has a suitable base 10 and at the upper end is in the form of an arched integral frame 11a. The knife of the machines of the type to which my invention relates is usually driven by an' electricl motor `12 mounted on the standardll` and' driving a belt 13 runningupwardly over the hub 14ofa revolving knife, here designated generally by the numeral' 15. The knife turns on 'a von shaft 16 supported in any suitable manner.'

in the frame 11a the shaft securing means including centeringscrews 17 engaging the" ends 'of the shaft. A guard 18 houses the knife'iV at the side at which the operator stands and at the opposite side separate guards 19 and 20 are ldisposed at the rear and front of the knife 15 the knife being exposed for a short section at the bottom of the-guards 19, 20.v The guards 19, 20 arel adjustably .secured by bolts 22, passing through the slots 22a-of said guard, ad-v ditional set screws 21 being employed to adjust the guards 19, 2O and hold the lsame in adjusted position.

The guard l18 issuitably fastened at .the

top and bottom' as at `182181 yto' theframe 11a and standard4v 11.`

My vimproved knife 15 is formed pracvtice of cast metal and generally of' dished form. In the grooved outer edge of the disk I employ an edge element 23 of ring form extending continuously about the disk and detachably held in Vposition in va concaveperipheral groove 15n of the disk, said element in practice beingv formed' of piano;

wire. At the back of the groovel')a the may terial of the body ext-ends radially outward a greater distance than at the front of the groove, the `lesserradiusat the front of the groove facilitating the removal of the annular element 23. The `metal at the rear side of the groove 15a takes the pressure when the knife is in use, the pressure being rearwardly. The ring element 23 is formed with a forwardly disposed oblique cutting edge 24 formed by grinding off obliquely the periphery 23 as at`25 and grinding an annular recess 26 within said cutting edge 24 to afford clearance for*l the removed flesh.

The'body of the knife 15 for the purpose hereinafter described has radially-extending slots 27 ipretenaljly 'three in nuniber, a greater number could be employed, and preferably extending from a point adjacent the hub 14; to the periphery of the knife. Each sector enclosed between the slots 27 and4 an approXiinately radial line dividing the saine are transverse holes 28. rlfhese holes 28 are adapted to receive the ingers of a Wrench.y

or other ltype 'oftooh 'fordetlecting said sectors laterally inward or outward toward the axis `of the 'knife to thereby contact the `circurnerence thereof to facili-tate `the removal; `of thefring element 23..

I would state in conclusion thatw-hile the `illiustratedy example constitutes a practical.
