LIVESTOCK OILER Larry R. Hall, Isabel, S. Dak.

Filed Oct. 16, 1959, Ser. No. 846,955

7 Claims. (Cl. 119-157) This invention relates to a novel livestock oiler of the type having a flexible applicator post, and adjustable, gravity seated valve means for feeding oil to the post, from a post mounted tank.

The primary object of the invention is to provide a more etfective and eflicient device of the kind indicated, which provides more positive and controlled feed of oil to the post, and from which the oil tank can be readily removed, for storage or other purposes, leaving the post in place, without subjecting the post to weather damage.

Another object of the invention is to provide a mechanically and structurally superior device of the character indicated above, which is more rugged and resistant to being damaged by animals using the same, and which can be more easily and conveniently serviced, when repairs or replacements of parts become necessary.

Other important objects and advantageous features of the invention will be apparent from the following description and the accompanying drawings, wherein, for purposes of illustration only, a specific form of the invention is set forth in detail.

In the drawings:

Figure 1 is a perspective view of a device of the invention, showing the same set into a base in the ground;

Figure 2a is an enlarged fragmentary transverse vertical section taken through the upper part of Figure 1 on the line 22;

Figure 2b is a similarly enlarged section taken through the lower part of Figure l on the line 2-2, showing, in phantom lines, the post removed by its spike; and

Figures 3, 4 and are enlarged horizontal sections taken on the lines 3-3, 44 and 5--5, respectively, of Figure 2a.

Referring in detail to the drawings, wherein like numerals designate like parts throughout the several views, the illustrated device comprises a vertical post assembly 10, a post supporting spike 12, securably engaged in a ground-engaging base 14, and an oil supply tank 16 mounted on the upper end of the post assembly.

The post assembly comprises a vertically elongated rigid metal tube 18 having an open lower end 20, in which is suitably secured a spider 22, and an upwardly tapered upper end portion 24, in which is suitably fixed, as indicated at 26, a stationary nut 28.

Fixed, as indicated at 30, to the center of the spider 22, is the lower end of a straight rigid rod 32, which rises axially and spacedly in the tube 18 to a point near to and spaced below the upper end portion 24. The rod has fixed on its upper end a spider 34 whose legs are fixed to the side wall 19 of the tube 18 at their outer ends, for holding the rod centered in the tube. At vertically spaced intervals, the rod 32 has fixed thereon upwardly tapered conical spreaders and deflectors 38, which have free lowerjedges 4t) which are concentrically spaced close to the tube side wall. -At locations immediately beneath the lower edges 40 of related--spreaders 38, the

tube side wall 19 is punched in to-provide'triangular oil receivers 42, spaced around the tube side wall, which dea cline to openings 44 through the side wall 19. The tube side wall 19 can be provided, if desired, with small holes or perforations 45 to supplement the openings.

Circumposed on and extending to a point near the lower end of the tube 18 is a jacket 46 of absorbent material, which is enclosed in a wire mesh sleeve 48, which serves to hold the jacket in place on the tube, protect the jacket against undue abrasions by animal contacts therewith, and to have the additional function of acting as a scratcher. Oil falling onto the spreaders 38 is directed outwardly to the receivers 42 which flow oil through the openings 44 and holes 45 to and into the absorbent jacket 46 and serve to prevent oil entering the upper end of the tube from falling therethrough from accumulating on the lower end of the tube without adequate contact with the jacket.

Securably circumposed on the lower end of the tube 18, is the upper end of a heavy helical spring 50, whose lower end is securably circumposed on the upper end of a heavy cylindrical spike 12, which is rigidly secured in a base 14, such as a concrete slab, embedded in the ground G. This flexible and resilient mounting of the post on the base 14 enables the post to be flexed harmlessly by animals rubbing thereagainst, facilitates application of oil to the rubbed areas, and serves to open and close an oil flow control valve assembly 52.

The valve assembly 52 comprises a cylindrical valve body 54 which has a threaded lower end 56 which is threaded downwardly in the nut 28, a threaded upper end 58, and a lateral flange 55 located between the ends. On the upper end of the valve body 54 is a reduced diameter upstanding threaded nipple 60, and a vertical axial bore 62 which extends through the valve body and is formed with a valve seat 64 at the upper end of the nipple 60. An inverted cup-shaped valve cover or cage 66 is threaded onto the nipple 60 and has a top wall 68 through which is axially threaded an adjusting screw 70, having a finger knob 72 on its upper end, above the cover 66, and provided with a lock nut 74 which bears upon the cover top wall 68. The screw 70terminates at its lower end in a reduced diameter pin 76 to contact the top of a ball valve 78 which is confined for limited lateral and vertical movement within the cover, relative to the valve seat 64.

The arrangement of the ball valve 78, the seat 64, and the cover 66 is such that whenever the post is tilted, by contact of an animal therewith, the ball valve is rolled laterally off the seat 64, so that oil from a supply tank 16 can flow through openings 82, provided in the cover side wall 84, enter the valve body bore 62, and fall into the tube 18, and onto the spreaders 38. When the post returns to its erect position, when released by an animal, the ball valve 78 is rolled back into the valve seat 64, so that flow of oil through the valve body is cut off. Downward adjustment of the adjusting screw 70 serves to decrease the flow of oil through the valve body 54, by limiting the amount of roll of the ball valve away from the seat, when the post is tilted out of erect position.

The valve body 54 also serves as the mounting for the oil supply tank 16, the tank having a conical bottom wall 86, having a nut 88 fixed in an opening at the apex thereof, which is threaded onto the upper end 58 of the valve body 54, and against the lateral flange 55. The tank is closed, and has a filling plug 90 in its top wall 92. The tank 16 can be removed from the post by screwing the same upwardly off the upper end of the valve body, while the "valve body is held stationary to avoid its being screwed out of the'upper end of the tube 18, the valvecove'r or cage .66 'being'small enough'in diameter to pass through the opening of the'nut 88 on the lower end of'the tank. -With the tank 16 removed from the post, water in the form of, rain or melted snow,

3 cannot harmfully enter the tube 18, because of the normally closed position of the ball valve 78, unless the post he tilted out of its erect position, and the spring can be'made stilt enough that expected winds will not tilt the'post :far enough to unseat the ball valve.

Although there has been shown and described herein a'preferred formof the invention, it is to be understood that the invention is not necessarily confined thereto; and that any change of changes in the structure of and in the relative arrangements 'of-cornponents thereof are contemplated as being within the scope of the invention -as defined by the claimsappended hereto.
