MACHINE FOR DOCKING LAMBS TAILS. APPLICATION HLED JULY 8.1920- Patented Dec. 6, 1921.

mm 5 M UNITED STATES PATENT" MACHINE FOR DOGKING LAMBS TAILS.

Specification of Letters Patent.

Patented Dec. e, 1921.

Application filed July 8, 1920. Serial No. 39 L791.

To all whom it may concern:

Be it known that I, RICHARD CoornHan- VEY, a subject of the King of Great Britain, residing atLethbridgdfrovince of Alberta, Dominion of Canada, have invented certain new and and useful Improvements in Machines for Docking Lambs Tails, of which the following is a specification.

My invention relates to a new and improved machine for docking lambs tails, and the object is to provide a machine that will perform the work intended more easily than has been able to be performed heretofore, by an easy and humane method without undue loss of blood by the lamb.

I attain these objects by the mechanism illustrated in the accompanying drawings, in

Figure 1 is a side elevation of the entire machine open ready for use;

Fig. 2 is a bottom plan view of the device Fig. 3 is a transverse vertical. section on line 3--3 of Fig. 1.

The machine preferably consists of a guard-piate 1 secured to the top of a standard 2 bolted to a suitable support 3. Se cured t0 the top side of the guard plate is a blade at, and pivoted as at 5 to the outer end of the guard-plate 1 is a lever 6, which is in the form of a blade as at 7 directly above the blade 4 and adapted to coiiperate therewith when the lever 6 islowered.

Fulcrumed to the standard 2 below the guard-plate 1 is alever 8, having secured to one of its free ends a metal plate or plunger 9, preferably made of copper or other heat-retaining element. This plunger is adapted to extend vertically through an opening 10 in the guard-plate 1 just beneath the blade 4. As the lever 6 is lowered to sever the tail of the lamb, a vertically-arranged spring-actuated actuating rod 11 is forced downwardly, its lower end being connected as at 12 to the opposite end of the fulcrum lever 8, this actioncausing the plunger or singer 9 to move vertically upwardly, and is thus brought-into contact with the lambs tail at the where it is docked.

It is desirab e to k ep this p ung r or singer 9 under heat to effect the proper slngelng of the freshly cut end of the lambs tail, and to effect this a torch or other heatmg element 13 is applied to the lower end thereof to maintain this plunger under a certain heat, the elfect of the heater plunger belng, as stated, to singe or close the bloodvessel of the freshly severed member.

In operation, the lever 6, together with the blade 7 assumes a position relative to the blade 4 (as disclosed in Fig. 1) to re-. ceive the lambs tail to be docked, whereupon the lever 6 is lowered, thus severing the tail and simultaneously actuating the heated plunger or singer 9, which, owing to the construction of the mechanism moves upwardly to singe the freshly severed portion to pro duce a more or less healing effect on the wound.

I claim:

1. A; tail docking device comprising a support, a blade aiiixed thereto, a lever pivoted to said Support and provided with a sharpened surface to cooperate with the fixed blade of the support, and a heated singer movable with respect to said support and arranged adjacent to said cutting edges adapted to sings the part being severed.

2. A tail docking device comprising a support, a guard extending laterally thereof, a fixed blade secured to said guard, a lever pivoted at one end to said guard and provided with .a sharpened surface adapted to coiiperate with said fixed blade, a heated vertically movable singer ,inounted upon said support and arranged adjacent to said fixed blade, adapted to singe the part being severed.

3. A tail} docking device comprising a support, a guard adapted to extend laterally therefrom in either direction, a fixed blade carried at the outer end thereof, a lever pivoted adjacent to said blade at the outer end of said guard and provided with a sharpened surface which is adapted to cooperate with said fiXed blade, a fulcrum lever mounted on said support below said guard carrying at one end a vertically movable singer which is mounted upon said support, arranged adjacent to said fixed blade,

and a spring-pressed actuating rod carried said first-mentioned pivotal lever to effect a at the opposite end of said guard and atsingeing of the part being severed, and a tached t0 the other end of said fulcrum lever heating element arranged adjacent to said 10 adapted to be actuated by the downward singer for maintaining a given heat thereto. movement of the first-mentioned pivoted In testimony whereof I affix my signature. lever, whereby the singer is caused to move 7 vertically upon the downward movement of RICHARD COUPE HARVEY.
