7 Claims. 1

The invention relates to stock oilers of the generaltype embodying an upright member. for the stock to rub against, and means for automatically supplying oil tothe periphery of said member.

The object of the invention is to provide a device of the above type which will .be of extremely simple and inexpensive form; yet hi hly efficient and free from valves or other relatively delicate parts which could cause-trouble.

Figure 1 of the accompanyin drawing is a side elevation showing the rubbing member in one of its tilted positions by means of broken lines.

Figure 2 is an upper end view,

Figure 3 is an enlarged vertical scctional'view, partly in elevation as indicated by line 3-.-3 of Fig. 1.

A preferred construction has .beenillustrated and will be rather specifically described, with the understanding, however, that within the scope of the invention as claimed, variations may be made.

A suitable base 5 is provided for anchorage to a floor or to the ground, and appropriately secured to this base is a rigid standard 6 preferably formed from a length of pipe. Welded or otherwise secured upon the upper end of this standard, is a flat horizontal disk I, said disk and standard serving to tiltably support the rub bing member 8. This member is of tubular form and is open at both of its ends. Within this member 8, near its upper end, is a horizontal partition 9 welded or otherwise liquid-tightly secured, to provide an oil chamber I in said upper end of said member 8. Oil discharge openings l l are formed through this member, from the chamber ID to the periphery of said member, said openings being spaced above the partition 9.

An oil tank l2 rests upon the upper extremity of the rubbing member 8 and closes the upper end of the oil chamber Ill. Two vertical rods I3 are preferably welded at their lower ends to the upper end of the rubbing member 8 to receive the tank l2 between them, and two angular positioning brackets M are also welded or otherwise secured to said member 8 to prevent movement of the tank l2 from its position between said rods it. A yoke bar rests on the tank 12, is apertured to receive the upper ends of the rods l3, and is held normally down against said tank by means of wing nuts or the like l6. Removal of these nuts and the yoke bar permit easy removal of the tank l2 for refilling.

5 projectin downwardly to a plane below the plane of the oil discharge openings ll. Except for this nipple I 8, the tank I2 is air-tight. Thus, air can enter said tank and liquid discharge from it only when the lower end of the nipple: i8 is 10 exposed. The oil discharging through this nipple rises in the chamber Ill until it forms a liquid seal preventing further extrance of air. into said tank. When this occurs, the oil level IS in the chamber I0 is somewhat below the openings l I and, therefore, no discharge of .oil will occur on the periphery of the rubbing member 8, until this member is tilted by stock pushing or rubbing against it. When such tilting occurs, one or another of the openings I l is lowered and the oil from the chamber I!) may discharge through it and run down on the periphery of the rubbing member 8 for application to the animalthat efiected tilting of the rubbing member. The periphery of this member is by preference provided with a more or less absorbent covering which becomes saturated with'the oil, said covering being shown as formed of a number of. turns 2-0 of rope.

I Due to the fiat contacting areas on the horipo zontal. disk 1 (or its equivalent) and the partition 9, the rubbing member 8 will be self-righting to an. upright position whenever it is released from a tilted position and hence,there is no danger of wasting any of the oil or other medicating liquid that may be used. As a safeguard, to prevent any possibility of a hog or other animal upwardly forcing the rubbing member 8 from the standard 6, an ordinary cap screw 2| may be threaded through said member 0 8 in position to underlie the disk 1, being downwardly spaced from said disk, however, a sufficient distance to prevent any interference with the required tilting movement of said member 8.

The base 5 is preferably about sixteen inches 5 in diameter and a half inch thick; the standard ,6 may Well be formed from one and one-half inch pipe; six-inch well casing is well adapted for constructing the rubbing member 8 and this member may well be say twenty-four inches long with its lower end supported six inches above the base 5. The partition 9 may be approximately two and a half inches down from the upper end of the member 8 and the openings ll spaced down about a half inch from said upper I end of the member 8. The oil tank I2 is preferably of about two gallons capacity, with a diameter of eight inches and a height of about ten inches. Three-eighth inch rods will suflice for the rods I3 and ordinary strap iron may be used for the lugs l4 and the yoke bar l5.

"It willbe seen from the foregoing that novel and advantageous provision has been made for attaining the desired end, and while preferences have been disclosed, possessing marked advan; 'tages from standpoints of manufacture and use; attention is again invited to the possibility -of making variations within the scope of themvention as claimed. r P
