V PEI/l TREATING AND CLEANING MACHINE.
Application filed May 1, 1920. Serial N0. 37 8,060.
To all whom it may concern: y I
Be it known that I, OHARLEs UoonLmNi, a sulnect of the lung of Italy, and a resident of Central Park, Nassau County, State of New forlghave invented certain new and useful Improvements in PeltTreating and leaning Machines, of which the following is. a specification.
My invention relates to machines for treating pelts of animals'such as foxes, rabbits, squirr ls, skunks, etc etc., and has for its object a construction whereby the pelts of such animals are more readily and completely cleaned and softened thanin prior constructions, and the process or operation of such ClGElIllllg and softening is performed at a great saving of time which now required therefor. To thisend I have "constructed a mechanism comprising two drums, said drums being relatively rotatable, one within the other, and by reason of such relative rotation and the provision of mixing blades and ribs, I attain a more complete, thorough and intimate mixing of the Sawdust which is employed in such drum for rubbing contact with the pelts for softening and cleaning the same. The employment of sawdust for this purpose is well-known, the sawdust, and the pelts to be cleaned and softened being ordinarily introduced within a single rotating drum and. the sawdust being preferably in a moist condition, the moisture serving to attain more particularly the desired softening effect upon the pelts. The objects of my invention, therefore, does not relate to that process, but relates to an improved mecha nism for better accomplishing the desired result.
In the accompanying drawings, Fig. 1 is a section taken on line 11 of Fig. 2; Fig. 2 is a plan view of Fig. 1; Fig. 3 is a cross sec tion on line 8-3 of Fig. 2 and Fig. 1 is a diagrammatic view showing the interior arrangement of projecting ribs and intersecting blades or cleats in the inner and outer drums respectively. Having reference to these drawings 5 represents the outer drum of my construction, which drum may be made either of metal or wooden slats and which is provided with the usual door 6 which may be hinged as shown at or otherwise secured upon the drum to give access to the interior of the drum. Uponthe inner circumference of this, drum 5, I secure a s ries of ribs 8 preferably diagonally disposed to the axis of the drum' and I secure upon these ribs a plurality of progecting blades or cleats 9 extending toward the journal 10,
the said cleats beingcarried by and intersecting the ribs Sand, in COHJUHCUOII with blades or cleats 11, hereinafter described,
serving to stir up andthoroughly mix the sawdust placed in the drum.
Within the outer drum anduponthe same ournal 10 thereof, I mount an inner drum 12, which may be made of any desired material such as metal or wood and provide upon the outer circumference thereof a :plurality of diagonally disposed ribs 13 somewhat similar to the diagonal ribs 8, and
I secure upon such ribs blades or cleats 1.1 similar to the blades or cleats 9, the respective cleats projecting toward one another for some distance, with a sufficiency of space therebetween, however, for the pelts and sawdust to pass between when the drums are rotated and the cleats or blades pass one another in their opposite rotation. As shown in the drawings, the blades or cleats have their outer surfaces rounded, so as to prevent tearing or otherwise injuring the articles to be treated. The two drums above described are. designed to be rotated in opposite-directions and for this purpose I have shown in my drawings a sleeve 14- secured upon one side of the outer drum, said sleeve being rigidly mounted upon the collar 15 of the beveled gear 16 which is rotatably mounted upon the ournal 10. This beveled gear 16 is engaged by a beveled gear 17 and through the rotation of the latter, rotation is imparted to the gear 16, its collar 15 and the sleeve 14 secured upon the outer drum. For the purpose of rotating the inner drum, I provide a gear 19, similar to the gear 16 but oppositely located thereto and likewise to that of the outer drum 5. The journal 10, 105
the drums, the gears, the gear-box and appurtenant parts are supported on a framework, which l'have generally indicated 1D.
mounted upon the journal 10 and rotated by the drawings by the reference letter A, and the beveled gear 17 as indicated is rotated by means of a :journal 21 carrying the usual loose and fast pulleys 22' and 23' at its outer end.
From the foregoing description it will appear that in my construction of machine for cleaning and softening pelts, I have provided means for securing continuous agitation of the pelts and the sawdust employed in that operation; that the oppositely rotating drums, one ithin the other, prevent the ad,- herence by centrifugal force of the contents of the drum to the inner circumference thereof and that my arrangement of ribs and blades intersecting one another in the course of rotation serve to continuously and effectively stir up the mass located between the respective drums.
WVhat I claim and desire to secure by Letters Patent is: I 1. In amachine for treatingv pelts, the combination of an outer rotating drum mounted upon a horizontal axisadapted to receive and confine sawdust and pelts to be treated, ribs secured to the, inner circumference of said outer-drum, an inner rotating drum, ribs secured upon the outer circumference of. said inner drum, the respective ribs being diagonally disposed to the axisof said drums, and mechanism for rotating said drums in opposite directions.
2. In a machine for treating pelts, the combination of an outer rotating drum mounted upon a horizontal axis adapted to receive and confine sawdust and pelts to be treated, ribs secured to the inner circumference of said outer drum, an inner rotating drum, ribs secured upon the outer circumference of said inner drum, the respective ribs being diagonally disposed to the axis of said drums, and extending from one end wall of the respective'drum'to the other, and mechanism for rotating said drums in opposite directions.
, 3'. In a machine for treating pelts the combination of'an outer rotating drum mounted on a horizontal axis and adapted to receive and confine sawdust and pelts to be treated, diagonally disposed ribs secured upon the inner circumference of said outer drum; diagonally disposed blades secured upon said ribs; an inner rotating drum, diagonally disposed ribs secured upon the outer circumference of said inner drum; diagonally disposed blades secured upon said ribs, both sets of blades havin rounded outer surfaces and mechanism. for rotating said drums in opposite direction.
