SHEEP-SHEARS HOLDER AND CONTROLLER.

Specification of Letters Patent.

Patented Apr. 3, 1917.

AppIication filed May 2, 1916. Serial No. 94,372.

To all whom it may concern:

Be it known that l, Berri Roos a citizen of the United States, residing at Idaho Falls, in the county of Booneville and State of Idaho, have invented certain new and useful Improvements in Sheep-Shears Holders and Controllers, of which the following is a specification.

This invention relates to certain new and useful improvements in sheep shears holders and controllers.

The primary object of the invention is the provision of a holder for sheep shears of the motor driven clipper form, the holder being so arranged as to automatically shut off the powerto the clippers when the latter are mounted thereon.

It will be understood that the clippers are to be held by the hand of the operator during the sheep shearing operation and while an electric motor is herein illustrated for operating the clippers, it will be understood that the device is equally applicable to any other driving power, the device being conveniently positioned for the operator to place the clippers upon the bracket, which operation. automatically opens the power switch or clutch, thus interrupting the motive power while a removal of the clipper from the bracket allows the clutch or switch to automatically close again con necting the clipper with the motive power for immediate use.

A still further object is the provision of a radially positioned block arranged with a clutch shifting slide upon which slide a mounting bracket is provided for repair of the sheep clippers, the block having a bearing leather or facing for engaging the clipper blades.

Vith this form of automatic control for the clipper motor, it will be seen that the shearer is enabled to place the clipper upon the bracket automatically throwing the clipper out of gear while leaving both hands free for manipulating the sheep during the shearing operation. The animal may then be held by one hand and the clipper released from the bracket with a downward stroke automatically throwing the clipper into gear. The device is therefore a time saver and of great assistance to shearers having a large number of animals to be shorn.

WVith these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and then claimed.

In the drawings forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views:

Figure 1 is a front elevation of the device illustrated in connection with a driving motor and switch, the clipper being positioned upon the bracket with the switch open.

Fig. 2 is a top plan view of the device.

Fig. 3 is a front elevation thereof.

Fig. 4 is a longitudinal sectional view taken upon line IV-IV of Fig. 3, and,

Figs. 5 and 6 are transverse sectional views taken respectively, upon lines VV and VIVI of Fig. 3.

Referring more in detail to the drawings, it should first be understood that the present invention broadly consists of a base block 10 preferably formed of wood and having a metallic slide plate 11 shiftably arranged in a central longitudinal groove 12 in the front face thereof, the said plate being provided with a special form of resilient bracket 13 adapted for removably receiving the sheep shears or clippers 14 to be supported thereby.

The block 10 may be rigidly secured to any convenientsupport such as a post or a fence board 15 by means of screws 16 arranged tirough receiving perforations 17 of the block. Retaining strips 18 and 19 are secured to the block 10 overlying the slide plate 11 and spaced from the upper and lower ends of the groove 12 while a spacing or bearing surface 20 in the form of a pad overlies the upper retaining strip 19 being ataptcd to receive the cutters or blades 21 of the clipper 15 thereagainst.

The bracket 13 is preferably formed of resilient material being substantially U- shaped having outwardly flaring side arms 22 and outwardly-extending inwardly opening loops 23 at the base of the bracket while a mounting shank 2 1' is carried thereby adapted to be screw-threaded into the plate 11 and retained by a lock nut 25, it being noted that two threaded receiving sockets 26 are provided for the shankQ l, allowing the bracket to be positioned normally at different distances from the pad 20 for holding clippers of different forms and sizes.

ll hile any form of mechanically driven clipper such as may be serviceably employed with the present device and operated by means of the usual flexible shafting 27, an electrical driving means for the clipper 14 is herein illustrated. The motor 28 is operatively connected to the switch poles 29 and 80 while the knife switch arm 31 is at tached by means of a cord 32 with the eye 33 in the upper end of the slide plate 11, it being noted hat coil springs 34-. normally retain the blades of the switch arm 31 closed upon the receiving terminals 36 of the line wires 37 and 38. The upper, end of the block 10 is provided with a central curved cut-away portion if? in which the upper end of the plate 11 projects It will l e noted that in connection with either a hand drive or an engine motive power if employed for operating the flexihis shaft 27 of the clipper, the clutch mechanism thereof would be normally closed in a manner similar to the switch arm 81 and with the cord 32 attached to the gear thereof, the gear would be automatically opened by the slide plate 11 in a manner identical to the present operation. In applying the clipper 14- to the bracket 13, the cutters 21 are forcibly engaged or slapped against the face of the pad 20, thus preventing any injury to the clipper mechanism when hanging the same upon the bracket 13.

It will be seen that with the switch arm 31 normally closed, the slide plate 11 will be in its dotted line position as indicated in Fig. 1, the clipper lat being removed from the bracket 13. At such times the motive power will be in full operation and the clipper blades 21 will be in continuous motion. Upon raising the clipper 14- upon the bracket 13, the weight of the clipper will draw the slide plate 11 downwardly, thus opening the switch arm 31 by means of the cord 32 and against the action of the springs 34:, thus interrupting the circuit and breaking the connection between the clipper and crates of this patent may be obtained for five cents each, by addressing 'hat ver motive power is employed. l/Vhen to again use the clipper, the handle e clipper is grasped and the clipper forced downwardly through the bracket 13 and the b; se loops 23 thereof, thus spreading the bracket arms 29. l i l1en the bracket is released from the weight of the clipper 14, the springs 34 will close the switch arm 31, thus drawing the cord 32 and slide plate 11 upwardly and the clipper being); in operative connection with the motive power, the blades 21 thereof will be set in motion and the device ready for immediate use.

lt will thus be seen that while an inexpensive and simple device is now presented, the same possesses great ability and fully carries out the objects for which it is intended. While the form of the invention herein shown and described is what is believed to be the preferred embodiment thereof, it is nevertheless to be understood that various forms, modifications and arrangements of the parts may be made without departing from the spirit and scope of the invention as claimed.

W hat I claim as new is r A device of the class described, con1pris mg a wooden base block having a longitudinal groove therein, a metallic slide plate shiftably arranged within the said groove and having one end thereof outwardly projecting from the block and provided with a perforation, a power controlling cord attached to the said plate perforation, spaced retaining strips carried by the said block overlying the said plate, a clipper receiving bracket having I6Slll6llb arms and base loops removably adjustably carried by the said plate between the said strips, and a bearing pad secured overlying; the upper one of said strips and adapted for engaging the clipper blades when a clipper is arranged within the said bracket.

In testimony whereof I attlx my signature.
