- Application filed January I6, 1909. Serial No. 472,635.

To all whom it may concern: I

Be it known that I, CHARLES Duroun, a subject of the King of Great Britain, and resident of Cambridge, county of Middlesex, State of Massachusetts, have invented an Improvement in Apparatus for Washing Skins, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing, like parts;

This invention has for its object the production of a novel apparatus for washing skins, it being especially designed for washing-sheep skins with wool on them, although the device is capable of use for washing other kinds of skins.

The device is of that type embodying a rotary tub adapted to contain the skins and provided on its walls with inwardly-proand also provided with a vertical shaft situated centrally of the tub and having outwardly-projecting agitators thereon, said shaft and tub being rotated in opposite directions.

The objects of my invention are to provide a novel form of agitator which will opmate to stir the skins and complete the washing thereof without injuryto them, and also to provide a novel device for removing the washed skins from the tub.

One embodiment of my invention will first be described and then the novel" features pointed out in the appended claims.

In the drawings,Figure 1 is a vertical section through a washing machine embodying my inventlon, 1 1g. 2

1s a top plan view of the tub and the device for removing skins therefrom; Fig. 3 is a section through the side of the ww, Fig. 2.

The tub in which the skins-to be Washed are placed is designated by 3 and in practice this will have a diameter of something like 12 feet and may be about 6 feet in depth. This tub is adapted to be rotated as usual in devices of this class, ed in any suitable way for this purpose. I have herein shown it as having rigidly secured to the under side thereof a large bevel gear 4 which isprovided with astud or tub on substantially the line stem 5 that is received in a suitably-supported' step bearing 6.; The gear 4 is driven b a beve l gear 7 which is carried by a sha t sustained in suitable bearings 8 and driven and it may be support" Situated centrally of the tub is a vertical I shaft 1 1, the lower end of which is journaled a suitable bearing 12 sustained by the tub, and the upper end of which is sustained ina bearing 13 secured to the ceiling or some overhead support 14. Theshaft has fast thereon a bevel gear 15 that is driven by a bevel gear 16 mounted on afshaft having. a driving pulley 17 thereon. The parts thus far described may have any suitable or usual construction-and orm no part of my present invention.

The tub has rigid therewith a plurality of blades or agitators 10 which are in the na-, ture of fins that extend obliquely from the wall of the tub, as plainly seen in Fig. 2. These fins are preferably Wider at the bot.- tom than at the top, as clearly seen in Figs. 1 and 3.

The shaft 11 carries a plurality of coop-- crating blades or agitators herein designated by 18. In the present embodiment of my in: Vention I have shown three such agitators and each is in the form of a fin or web ex tending radially from the shaft and wider at the top than at the bottom.

in my preferred construction, the lower and of the shaft 1]: ismadetriangular in shape, as shown at 2'1, and the blades 18 extend from the flat faces of this portion of the shaft, as clearly seen in Fig. 2. I- find that agitators or blades of this character serve to'effectua-lly wash theskins without any danger of their becoming torn or in- .jua'ed. My invention also comprehend-s a novel device for removing the skins from the tub .3. This device is in the form of an elevator or conveyer adapted to be placed in the tub in such a osition that as the tub rotates, the skins Wlll be forced by the rotation of the tub onto said elevator, by which the skins are carried up over the top of the tub. I have herein shown this elevator as in the form of an endless belt elevator. It comprises two side pieces 22 which receive between them the two

rolls

23 and 24 over which the endless apron 25 passes. The side rails 22 are pivoted at 26 to a stand orsup port 27 and each side rail has an angular shape, as clearly seen in Fig. 1. The side rails 22 are'positioned so that the ends thereof carrying the endless apron 25 stand at one side of the shaft 11, and the shape of side rails 22. Vhen the skins have been washed and it is desired to remove them from the tub, the elevator is placed in the full line position F igu 1 so that the endless apron 25 is positioned within the tub. The tub is then rotated in'the direction of the arrow Fig. 2, and at the same time-the endless apron 25 is operated by.,turning the roll 24 in a direction to carry the upper run of said apron upwardly. Thismay be accomplished by any suitable means and I have herein shown for this purpose a gear 33 fast on the roll 24 and meshing with and driven by a gear 34 which is provided with a handle 35. The rotation of the tub carries the skins up against the upper run of. the endless apron 25, and by operating said endless apron, these skins are elevated from the tub and may be deposited through the space 38 between the side rails 22.

The shape of the

agitators

10 and 18 is such that when the endless apron 25 is lowered into the tub, as shown in full lines Fig. 1, said agitators will pass either side of the side rails 22, as shown in F ig. 3, the widest part of the agitators l8-pass1ng over the elevator and the widest part of the agitators 10 passing under the elevator. I will preferably provide the endless apron 25 with hooks 40 which are adapted to take hold of the skins and facilitate their being elevated by the apron. I have shown at a pipe by which the tub may be filled with liquid and at a valve pipe by which the liquid may be drained from the tub. My improvement, therefore, provides a simple mechanism for thus doing away with the tub.

laborious operation of lifting the skins out by hand as has been heretofore done.

Havin fully described my invention, what I cIa Letters Patent is 1. In a machine for washing skins, the

combination with a tub, a shaft situatedelevator for removing the skinsfrom thev tub, and means whereby said elevator may be inserted into the tub orremoved therefrom.

3. In a machine for washing skins, the combination with a tub, a shaft situated cent-rally of the tub, and means to rotate the tub and shaft in opposite directions,of an endless belt elevator, and means for sustaining said ,elevator whereby it may be placed within the tub for removing skins therefrom or placed in a position above the 4. In a machine for washing skins, the combination with atub and means forrotating it, of an elevator comprising .two .side rails pivotallyv mounted so as to permit one end thereof to be, carried into the tub or elevated above the" tub, an endless belt conveyer sustained by said end of said side rails,

and means for operating said 'conveyer.

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