05cm? GEREKE 'BY ZV M A TTORNE Y Patented Nov. 6, 1945 DEHORNING UNITED. STATES PATEN OFFICE Oscar Gereke, Stockett, Mont. Application October 26, 1944, Serial Nd. 560,480 2 Claims. (c1. 128-235) cator for the purpose described and whereby such paste may be handled, used and applied to the horn buttons of a calf, without the danger of the operator burning his hands because of the acid nature of the paste used.
A further object of the invention is to, provide a dehorner paste applicator comprising a tube or cylinder adapted to hold and contain the dehorning paste, the same having an opening or port in one side thereof for filling in the paste, and being formed at its outer or working end with a reduced and shortened duct adapted for receiving measured quantities of the dehorning paste, and a spring set plunger dimensioned to enter the said duct and force the measured portion of dehorning paste therein outwardly and upon the horn button of the calf under treatment.
With the foregoing objects in view, together with such other and additional objects and advantages as may appear from the specification, attention is directed to the accompanying drawing as exemplifying a preferred embodiment of the invention, and wherein:
Figure 1 is an elevation of the implement, the subject matter of this invention, the interior confor receiving the porous rubber pad 6 which is struction and features thereof being indicated in dotted lines.
Figure 2 is a longitudinal section on the line 2-2 of Figure 1 Figure 3 is a detail view in perspective of the closure cap for the working end of the implement.
Figure 4 is a cross section Figure 2. l
The invention comprises a cylinder, barrel or tube represented generally at l, the same being formed on one side with the filler port and cap as represented at 2, and through which port the dehorning paste (not shown or indicated) may be filled into the cylinder for use. The outer or working end of the cylinder or barrel I is filled in as at la to provide the reduced and relatively short measuring duct 4 adapted for receiving a measured portion of the dehorning paste as forced thereinto from the cylinder l. The workon the line 44 of ing end of the cylinder is concaved out as at I b cemented therein. A plunger rod 3 is reciprocably and axially extended through the cylinder I, the same being provided with a hand disk 3a at its inner end, and with a plunger 5 at its outer or working end, threaded as shown upon the end of the rod, and adapted to nicely enter the measuring duct 4 of the cylinder l for the purpose of ejecting the charge of dehorning paste as same may be filled therein. The plunger rod 3 reciprocably passes through a screw cap I l threaded at H] upon the hand end of the cylinder or barrel I, the point of passage of the rod through the cap being indicated at 9 in the drawing. A partition web I0 is extended transversely of the interior of the cylinder I in spaced relation to the cap II, for providing a spring chamber, and within which chamber is mounted the retractile coil spring 1 which is anchored at its inner end to the web I0 and at its outer end to a stop pin 8 passed through the plunger rod 3.
In use the cylinder l is suitably filled with the dehorning paste through the port 2, a portion of which paste fiOWs into the measuring duct 4. The porous pad 6 is then positioned over the horn button of the calf and the plunger rod 3 is forced outward by pressure upon the hand disk 3a, thus forcing the plunger 5 into the duct 4 and in turn forcing the charge of dehorning paste in the duct out through the porous pad 6 and onto and around the horn button of the calf. One such treatment is ordinarily sufiicient to kill the further growth of the calfs horn. After each such operation the spring 1 withdraws the plunger 5 from the duct 4 and permits the latter to refill with the dehorner paste for further operations. When not in use the pad 5 may be protected by means of a, cap or cover I2 which maybe slidably seated upon the working end of the implement, as indicated in Figure 1.
While I have here shown and described a specific embodiment of the invention and specific structural features thereof, it is understood that the embodiment as shown and the structural features thereof may be changed or modified as desired, within the scope however of the appended claims.
I claim: 1. In a device of the kind described, a cylinder for holding a dehorning paste, means for filling a dehorning paste into the cylinder, the said cylinder being formed with a reduced and shortened duct for receiving a measured charge of the dehorning paste, means for discharging the contents of the duct, the working end of the said cylinder being concaved for receiving a porous pad, and a porous pad mounted in the said Worka cage at the inner or hand end of the cylinder adapted for receiving a coil spring, a plunger rod passed slidably out through the said cage'at the inner hand end of the cylinder, at plunger at the outer end of the plunger rod adapted to slidably enter the said measuring duct of the working end of the cylinder, 2, retractile coil spring seated over the inner end of the plunger rod within the said spring cage, the ends of the spring being anchored to the inner hand end of the cylinder and the said cage, whereby the plunger rod and plunger are automatically retracted after each outward" movement thereof, the outer working end ofthe cylinder being chambered out for receiving a, porous pad, and a porous pad seated within the said chambered end of the cylinder.
