ALBERT BAJOHR, OF BROOKLYN, NEW YORK.

DEFLES HINGMACHINE.

Application filed April 22, 1916.

To all whom it may concern:

Be it known that I, ALBERT BAJoHR, a citizen of the United States of America, residing in the borough of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Defieshing-Machines, of which the following is a specification.

The present invention relates to defieshing machines for operating upon fur skins and the like and the object of my invention is to provide a simple and effective apparatus for assisting in this operation.

In the accompanying drawings, Figure 1 is a side elevation partially broken away of a machine in which my invention is embodied in one form; Fig. 2 is a front elevation of the same; Fig. 3 is a section on the line 3-3, Fig. 2; Fig. 4 is a partial side elevation of a modified construction; Fig. 5 is a broken front elevation thereof; and Fig. 6 is a plan thereof, with the guard partially broken away.

The present machine is of the type adapted to cut or scrape from the inner face of fur skins the adherent flesh or fat to clean the skins and to render the latter of uniform thickness throughout.

The apparatus in the form shown in Figs. 1 to 3 comprises a standard 10 of any suit able construction, preferably channeled on one face at 11 to receive the slide block 12 which is held in the channel 11 by plates 13, the inner edges of which overlie the margins of the channel, thus forming a guideway in which the slide block works. Pivoted at 14 to the slide block is the upper end of a link 15, the lower end of which is mounted on the crank pin 16 on a head 17 of shaft 18 driven by the pulley 19 and supported in a bracket 20 fast to one side of the standard. A straight edge knife 21 is se cured to the slide block 12 by means of clamping screw bolts 22. In the particular form shown the slide block is of T-shape in section the web 23 being slotted to receive the back of the knife. From each side of the standard project stationary guards 24 secured to the standard by screws 25. The edge of the knife lies between the free edges of the guides 24 and projects slightly beyond the same, the distance being rendered adjustable by the slots 26 in the knife blade through which the clamp bolts 22 pass.

The operation of this apparatus is obvi- Specification of Letters Patent.

ous. Upon a drive of the shaft 18 the crank 16 imparts a vertical reciprocating motion to the blade 21 and the skin (diagrammatically represented at 27, Fig. 3) is pulled across the edge of the blade by an operator standing at the rear of the machine.

In the modification shown in Figs. 4:, 5 and 6, the blade 28 is mounted upon a shaft 29 supported in a pair of bearing blocks 30, 31. The shaft 29 is oscillated by a. crank 32 connected to the upper end of the link 15 to which a vertical reciprocating motion is imparted in precisely the same manner as in the construction previously described. In this form the guards 33, 34 are arcuate in shape and are permanently secured by their screws 35 to the head of the standard. In order to effect the adjustment of the blade 28 with relation to the guard, the lower bearing block 31 is beveled on its lower face 36 and rests upon the beveled upper end 37 of the standard. The bearing blocks are secured together and to the standard by means of bolts 38, 39 which pass therethrough and through the slotted flanges 40 on opposite sides of the standard. On the adjustment of the knife 28 with relation to the guards 33, 34, the bolts are moved in the slots 41 in the flange and tightened by the screwing up of the nuts beneath the flange. Such adjustment requires some freedom of the link 15 for angular displacement, and in this construction there is therefore no confined slide block (as 12) so that in the several positions which the link 15 may occupy it is at times out of the vertical. This is no detriment, however, to the proper operation of the shaft 29.

The operation of this modified form of knife is substantially the same as that previously described except that the knife moves back and forth in an are instead of in a plane. The skin is drawn across the blade in the well understood manner above mentioned.

Various modifications of construction will readily occur to those skilled in the art without departing from what I claim as my invention.

I claim:

1. A machine for defieshing furs and the like, comprising a standard, a knife supported at the head thereof, means carried by the lower portion of the standard for imparting to the knife a back and forth movement, and guards arranged on opposite sides of the knife beyond which the edge ofthe knife slightly projects.

2. A machine for defieshing furs and the like, comprising a standard, a crank shaft:

mounted in the lower portion thereof, an upwardly extending connecting rod the lower end of which engages said crank shaft, a knife operatively connected to the upper end of said rod and receiving a back and forth motion therefrom in'combination with guards on opposite sides of said knife and beyond which the edge of the latter.

slightly projects.

3. A machine for d'efleshing furs and the like, comprising a standard having a vertical channel-in one face, aslide block working in said channel, a knife carried by said slide block, guards extending from opposite sides of the standard and embracing said knife, the edge of which projects slightly beyond the guards, a crank shaft shaft supported. on the standard, an eccentrio on the shaft and a link' connection between the slide block and eccentric for the purpose described.

A; machine for defleshing furs and the like, comprising a standard having an undercut vertical channel in one face, a slide crank shaft supported on the standard and an operatlve connectlon between said crank block working. in said channel and having an outwardly-projecting split fin, a defleshing knife clamped in said fin, guards on op posite sides of the knife and beyond which the edgeof the latter slightly projects, a

shaft and slide block for vertically reciproeating the latter.

6. A machine for defieshing furs and the like, comprising a standard, a vertically arrangedknife supported thereby, stationary guards arranged on opposite sides of the knife and beyond which the edge of the knife slightly projects, means for imparting a back and forth motion to the knife and means for adjusting the position of the knife with relation to said guards to determine the eXtent to whichthe knife edge proj ects beyond the guards.

7. A machine for defieshing furs and the like, comprising a standard having'an undercut vertical slot in one face, a slide block confined in said slot, a knife carried by said slide block, stationary guards on opposite sides of said knife and'beyon'd which the edge of the knife slightly projects, means for adjusting the knife with relation to-its supporting-slide block to vary the extent of projection of the knife edge beyond the guards and'means for reciprocating the slide blockon the standard.

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

ALBERT BAJOHR.
