With thev foregoingandxother object-s in view, I havedevsed the device, tWO arrangements 0f whth,are vshown in the accom- 4'panying drawing, similar reference` char- Macters being employed throughout the various figures to indicate corresponding. elements. In this drawing, Y Y t g i AFigl l5 is a side .elevation showing a device constructed according to` my invention, the

Fig. 4 is a view .similar to .Fig.; l of a somewhat dierent arrangement but valso I have. found thatbyproviding the surface .of a cylindricalvroll witha large number of small teeth undercut or inclined in the directionof rotationl ofthe roll, if this roll is given a relative rotation adjacent the wool side of a sheep skin these teeth will Y iirstV act to lay the fibres in more or-iless .parallel relation and thattheywill then .wrap themselves about the roll7 as shown lat (Ff) in Fig. l, and further rotation of 'the roll or a relative lateralmovementthereof will pull the fleece from 'theskin VThis Y ample,a cylindrical piece of steel withthe roll may .be of any 'suitable material7 `for exnr teeth cut in the surface and thenk hardened,

or a roll of suitable material may bevcovered l with'la shark skin arranged so that the line teeth of Athis skinare all inclinedin one direction landmlocatedi in planes"extending transverselytorhe'axisofthe m11.. ns inde C Y' catedin Figs. l .and 3, I have found thatA Such a` roll ifused vas indicated above,` will first lay out the members of the fleecel in lSubstantially parallel relation andV will cause, them 'to wrap themselvesl ontothe surface of the roll, and will then pull them roll-and by giving ita combined rotaryand yaway and separate themV fromA the skin.

bodily movement over the fleece side of the p y skin it can pull this fleece from the skin. l

yItis, however, preferred to operatethe roll by power andvprovide mechanical means associated therewith to present the skin with the `leeceto the, surface of theroll. I have shown `in Fig. l somewhatdiagrammatically an arrangement ofdevices for this purpose.

`In'this figure, 10 is the work roll which may be rotated at the proper speedbyany suitable teeth 1l inclined to point in the direction'of ymeans, not shown', the, directionV of rotation s' 'i lbeinglindicated by the arrow, and the surface 'of this roll is provided with small inclined y rotation. 'These teeth, as indicated above-,

they may be provided by fastening a shark skin tothe surface of thefroll by any suitable means, such as' cement. The diameter Y may be formed by cutting them onthe surface of a steel roll and then hardening or of the roll should betsuiflcient `so that theH per cloth having fine 'bristles or bristle-like vwires 13, and this isrotatedso that its surfaceV speed .is greater than that of theV working roll 'and in the. samel direction: so that the teeth 13 will catch the rear endsof the'.

kfleece on the work roll and strip it fromthe vibrating Wires'14, which may be vibrated by means of a roll'15 running in a toothedvvvheel 16, the stripped fleece being deposited` on a conveyor belt whichit maybe carried to any desired location.

To secure best results and toprevent in-f jury to the surface of the skin by the Work roll it should beheld tauton suitable vsupport While it is being moved past the surface ofthis roll." In Fig. 1 'is shown a painoi y feedrolls 18-to the'rear of the 'Workioll 10,

and these Vrolls are-geared to'rotate 'together by' spur 'gears 19; In order-to secure a firm grip on-the skin 20 the vsurfaces Yof these rol-ls are'provided with longitudinally ezitending grooves and ribs 21"Which intermesh in Aproper'sp'aced relation as' the vrolls arerotated and draw th'eskin past the Worki -ing roll.l I'alsoprovide-a-supportingroll-22 overwvhich the skin passes and Which holds itin properfspaced relation -from the surface ofthe-Working roll; Y The skin is held taut byy a suitable means'ion the-other side of xthe roll.V In Fig. 1, I-haveshoWn-aslovvly rotating drumv 23 on which the skin may be clamped by -a 'suitablemeand as for instance,

the clamps 24..- I'have shown only a 'few of these clamps, it beingunderstood that these clamps-are mounted on the opposite ends of the drum` and are .substantially equally spaced throughout-'the circumference of the drum In the. form-shown they comprise brackets Q5 secured vto-ithe drum to which the clamps are ,pivoted, 'and the.. clamps each have' a rounded extension QG-.to yengage the topsurface offtheskin andv clamp it/to the surface of-,zthedrumzunder the action of the vspring- 27.

As there may be p'lenty of power used it is not necessary to use a depilatory to loosen the fleece intherlskin.
