9v Claims.

This invention relates in general to a device adapted for use in dairies, and in particular the invention is directed to, and it is one of the objects to provide, a cow teat medicator.

In order to prevent spreading of certain diseases, such as mastitis, from one cow to another in milk-cow herds, it is desirable, and often necessary, to apply a disinfectant solution to the teats of the cows after milking, and the present invention is designed for this purpose; the device being hand supported and operated to readily and quickly elect treatment tothe teats of a cow after milking.

A further object of this invention is to provide a device for the purpose described, which cornpassage between the tank and the lower end of said cup, and a finger actuated pump associated with the tank `and teat cup operative to pump fluid from the tank upward into the teat cup; a check valve being interposed in said passage to prevent back-flow of uid from the cup to the tank, and an overflow pipe leading from the cup adjacent its upper end downwardly to communication with said tank. y

A further object of the invention. is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purpose for which it is designed.

These objects I accomplish by means ci such structure and relative arrangement of parts as will fully appear by a perusal of the following specication and claims.

The igure of the drawing is a side elevation of the device, partly in section.

Referring now more particularly to the characters of reference on the drawing, the device comprises a relatively small upstanding tank I formed at its upper end with a relatively large diameter neck 2 threaded for the reception of a screw cap 3. A handle 4 is disposed outwardly of and alongside the tank I, and includes an attachment finger 5 which projects inwardly to xed connection with the top of cap 3 to one side (Cl. 12S-248) be seen that not only is the cup t supported from the tank but a passage P is formed therebetween.

A reciprocating sleeve pump, indicated at I0, is disposed in the tank and is mounted at its upper end in connection with the cap 3 and in communication with the passage P. rIhis reciprocating sleeve pump includes an upwardly opening ball check lI at the lower end, and another upwardly opening ball check I2 in the nipple 8. f

Sliding movement of the reciprocating sleeve I3 of the pump is accomplished by means of a pull rod i4 which extends from an ear I5 on said sleeve upward through an opening in the cap 3 to a ter'- mination in a head I 6 a short distance above said cap. IA finger actuated lever Il is secured at one end in loose play connection under the head I2 and is supported intermediate its ends for rocking movement by a fulcrum element It; the otherl and outer end of the lever Il being formed asa linger piece I9 disposed above the handle 4. A compression spring 2Q surrounds the rod It between the ear I5 and cap 3 whereby to normally maintain the sleeve I3 in lowered position and with the ball check I I adjacent the bottom of the tank.

A pair of oppositely disposed overiiow pipes 2I communicate with the cup 6 adjacent 'but short of its upper end, and thence extend downwardly to the cap and through which said pipes open at their lower ends. The cap is formed at any con.- venient point with an air bleed-opening 22 from which air can escape upon overflow of iiuid into pipes 2| and return of such fluid to the tank.

In use, the tank I is filled with the fluid disinfectant and the operator grasps the handle 4, and by means of which handle the device can be easily manipulated.

Holding the device in an upright position the operator actuates the linger piece l up and down, which in turn actuates the pump I0, pumping fluid from tank through passage P into the teat cup 6. The check valve I2 functions to prevent back flow of fluid from the cup into the pump. The operator continues such pumping action until the cup E is iillcd to a point adjacent the upper end 'of overflow pipes 2i. Thereafter the device is manipulated so that the cows teats are projected, one at a time, full length into the cup t, so that the fluid disinfectant, in said cup successively treats the teats.

In practice I prefer to use an antiseptic solution which comprises a base of mineral oil to which the disinfectant and other ingredients are added. The use of a mineral oil as the base is advantageous in that the solution when used not only disinfects but conditions the cows teats, maintaining the same soft and pliable, which enhances milking, prevents chailng, and heals small cuts and abrasions. For example, in the process of machine milking, the milk duct or teat opening of some cows often becomes sore and inflamed, which in turn causes the cow to hold her milk, making her a slow, hard cow to milk. I have found that after using the medicator with a solution as above, these ducts become soft and pliable, thus enabling the use of milking machines on cows that otherwise would have to be milked by hand.

From the foregoing description it will be readily seen that I have produced such a de vice as substantially fulfills the objects of the invention as set forth herein.

While this specification sets forth in detailthe present and preferred construction of the device, still in practice such deviations from such defined by the appended claims.

Having thus described my invention, what I claim as new and useful and desire to secure by Letters Patent is:

l. A portable medicator for cow teats, comprising, in unitary relation, a tank adapted to receive a fluid, an upwardly opening teat cup 'mounted on and upstanding from the tank, means forming a passage from the tank to the cup, and means mounted in fixed connection with the tank to pump fluid from said tank to the cup.

2. A portable medicator for cow teats, comprising, in unitary relation, a tank adapted to receive a fluid, an upwardly opening teat cup mounted in adjacent and fixed connection with the tank, means forming a passage from the tank to the cup, and means mounted in fixed connection with the tank to pump fluid from said tank to the cup; said last named means comprising a hand actuated pump, said pump including a check valve opening toward the cup and functioning to prevent back-flow of fluid from the cup to the tank.

3. A portable medicator as in claim 2 in which the teat cup is disposed above the tank; and an overflow pipe connecting at one end in communil cation with the cup adjacent the upper end of the latter, and connecting at the other end in communication with the tank, the tank having a relatively small bleed hole in the top thereof. 4. A portable medicator for cow teats, comprising, in unitary relation, a tank adapted to receive a fluid, an upwardly opening vertically elongated teat cup mounted in rigid connection with and upstanding from the top of the tank, means forming a passage from the tank to the cup at the bottom of the latter, a pump mounted in the tank in communication with said passage operative to pump fluid from the tank to the cup through said passage, a handle on said tank at one side thereof, and hand actuated means to operate the pump.
