Patented Aug. 8, 1933 UNITED STATES r ori-ICE HAND MECHANICAL FLEECE DEBURRING MACHINE Application February 17, 1931, Serial No. 516,492, and in Great Britain March 22, 1930 16 Claims.

This invention relates to apparatus for use in de-burring the wool or hair held by the skin or pelt of an animal, and is more particularly adapted for use in de-burring the wool or of a live animal such as, for example, a sheep before the latter is sheared.

The object of the invention is to provide mechanically operated means which can be conveniently applied and guided by hand for this purpose.

According to this invention I provide mechanically driven de-burring apparatus adapted to be manually applied and to be so guided to eect the removal of burrs or the like from hair or Wool attached to the skin or pelt of an animal.

In order to carry the invention into efect I may provide a frame or support of any desired width, in which is rotatably mounted, on suitable bearings, a winged roller comprising a member provided, preferably in spiral formation, with a series of de-burring loops or beaters oi any convenient construction suitable for the extraction of burrs or the like from wool or hair. The winged roller or de-burring element is rotated by any suitable means such as a flexible shatt driven from a manually operated or power driven device.

In order to regulate the penetration of the beaters into the wool or hair I provide suitable guiding means which may, for example, comprise spring held rollers extending longitudinally of the de-burring element, or alternatively I may provide spring held guiding plates preferably arranged transversely of the de-burring eleg ment and at the outer ends thereof.V The guiding means, when in the out-o-action position, are level with or extend below the lower surn face of the downwardly directed beaters; the spring controlled movement of the guides may be adjustable and the resilient mounting of the said guides enables the operator to press the beaters, when in use, more or less deeply into the ileece, and so follow the contours of the animals body, in order to engage and so remove the burrs or foreign matter from the wool or hair.

In order that the above description may be more clearly understood, one form of the apr paratus is shown in the accompanying drawings 00. in which:

Figure l is an elevational view of a manually applied de-burring machine;

Figure 2 is a plan view thereof;

Figure 3 shows a corresponding view of the machine in end elevation;

(Cl. 11S-91) Figure 4 is an elevational View of a moded form of guiding member, and

Figure 5 is a fragmentary view at a right angle to Figure 4.

Referring to Figures l, 2 and 3, a four sided frame or supporting block 10 is provided, at each or" its four corners, with a vertical extending housing or guide member 11. End ilanges 12, extending downwardly from the frame l0, are adapted to house suitable bearings in which is rotatably mounted a spindle or hatt 13. 'Ihe latter carries a cyhndricalmember 14v on which are arranged, preierably in spiral formation, a. series of burr disengaging loops or beaters 15. A hollow extension piece l5 is bolted to the face ci one oi the end anges 12er formed integral therewith to provide a handle for the apparatus,

while anextension lSaof the shaft 13 extends through the hollow member 16 to form a con- -ection for. the mechanical ldriving means employed to rotate thel deeburring element. Guiding rollers 17 extending longitudinally of the frame and below thereof, are positioned to either side of` the cle-burring element. Theguide roll- 17 are rotatably mounted in bearing members 18 which latter are supported from the main frame 10 by means of upwardly extending stem-pieces 18d. The latter are slidably supported in the housings 11v as shown in Figure l. .Each stem-piece 18a is provided at its upper extremity with a disc or flange 19 which slidably lits in the housing 11 and serves as a seating' for a helical compression spring 20. The upper extremities of the guiding members 1l are drilled and tapped to receive threaded plugs 21 by means of which the compression,exerted by the hellcalsprings 20 upon the rollers 17, may be varied. The lower extremity of each stem-piece 18a is threaded to engage the locking nuts 18h which latter serve to adjust the positions oi the rollers, relative to the beaters 15 when the machine is in use. Flanged mem.- bers 22 are inserted in the lower extremity of each housing 11 to retain in the housing the respective discs 19 and springs Y20. The members 22 may be retained in position by set screws as shownY in Figure 1.

In. operation, the machine is connected, by means of a iiexiole shaft for instance, to a convenient source of driving power and isheld, whenin operation, by means of the handle 16.

The manner of application is similar to that of using power driven fleece shears. When applied to the iieece of a live animal such as, for example, a sheep, the latter is positioned as for the shearing operation and then the de-burring machine is applied to the fleece. By suitable hand-pressure upon the machine the guiding rollers are pressed upwardly, as shown in chaindotted lines in Figure 3, against the compressive force of the springs 20 and the beaters are thus allowed to penetrate more or less deeply, as desired, into the fleece. The latter is parted in a regular manner and the burrs or similar foreign matter removed.

A suitable opening 10u. (Fig. 1) is provided in the front side of the frame 10, to provide a passage for the clearance of the burrs as the latter are freed by the revolving beaters.

Deflecting plates, which it is not necessary to.

illustrate in the accompanying drawings, may be provided to deflect the freed burrs and so prevent the latter from again alighting on, and adhering to the de-burred object. A receptacle 25 may be attached to the machine in an easily removable manner, as shown more particularly in Figure 3, in order to collect the burrs thus removed from the de-burred object, and liquid nozzles could be associated with the de-burring element in order to spray water or suitable liquid compounds upon the object during the deburring thereof.

In an alternative construction, as shown in Figures 4 and 5, the guiding rollers 17 are replaced by curved plates 23, which latter are positioned transversely of the de-burring element and at either end thereof. Each plate 23 is resiliently supported in a manner similar to that above described in reference to the rollers 17, and the guiding plates act in a similar manner; or each spring support may be provided with a separate curved plate or surface adapted to rest upon and travel over the surface to be treated. If desired, both the guiding rollers 1'7 and plates 23 could be incorporated in the one machine in which case the spring housings 11 would be modified accordingly.

It will be appreciated from the above descrip- 45. tion that lmore than one de-burring element together with lthe corresponding beaters may be provided in the one machine and driven by a suitable arrangement of gearing. The single deburring element also could be rotated through a geared drive instead of through a direct drive as shown in the accompanying drawings. The de-burring element may comprise any type of roller or support on which the beaters would be arranged as desired.
