H. IHv STEFFENS AUTOMATIC HOG OILER Filed Nov. 7, 1945 acs Inventor Patented Sept. 6, 1949 UNITED STATES PATENT DFFICE AUTOMATIC HOG OILER Herman H. Steffens, Corder, Mo.

Application November 7, 1945, Serial No. 627,237

My present invention relates to improvements in hog oilers and has for its primary object to provide means whereby hogs may do their own ciling.

Another object of this invention is to provide an oiler which operates to oil a hog when he stops to scratch himself beneath the oil container.

A further object of my invention is to provide a scratching pole for hogs that automatically causes the hog to be sprayed with oil.

Other features and advantages will become more readily apparent from the following description and the accompanying illustrative drawings in which:

Figure 1 is a side elevational view of my improved hog oiler,

Figure 2 is a front elevation thereof, and

Figure 3 is a top plan view.

In the above drawings as well asin the specication to follow, the same characters of reference indicate the same parts throughout.

While one embodiment of my invention is illustrated in the above referred to drawings, it is tc be understood that they are merely for the purpose of illustration and that various changes in construction may be resorted to in the course of manufacture in order that the invention may be utilized to the best advantage according to circumstances which may arise, without in any way departing from the spirit and intention of my device, which is to be limited only in accordance with the appended claims. And while I have stated the primary neld of utility of my invention it remains obvious that it may be employed in any other capacity wherein it may be found applicable.

My invention I0, consists of a suporting pole I I, the end I2, of which is sunk in the ground in a hog lot (the post may be a fence sustaining post) and upon the top I3, of the post is secured a shelf I4, of a size to support an oil container I5. A band I'B, secured to the lower end of the post has secured thereto annularly disposed upright strips I1, I8, etc., the upper ends I9, 20, 2|, etc. project far enough above the shelf to form arms for securely holding the tank I5 thereon. The portions 22, of said strips are nailed to the edge of the shelf I4.

The tank I5, is provided with a faucet 23, to which is secured a bracket 25, to the outer end 26, of which is pivoted a lever member 21, having a right-angular end 28, to which is bolted the rightangular terminal 29, of a strap 30, the end 3l, of the vertical portion 32, of which is bolted to the upper end 33, of a scratching pole 34, the lower 2 Claims. (Cl. 119-157) end 35, of which is hinged to the projecting portion 36, of said band I6. The pole 34, inclines outwardly from its hinged end. A leg 31, is secured at its upper end 38, to the table I4, and at its lower end 39, to the band I6.

Fixed to the upper part of the pole 34, is a rod 42, the end 4 I, of which projects through a bore 42, in the leg 31, and between said leg and the pole a spring 43, is coiled around said rod 40, whereby the upper end of the pole 34, and with it the member 3U, are normally held outwardly. However, when a hog leans against the pole to scratch itself the pole and its upper'adjunct will be pushed in causing the member 21, to actuate the valve stem 44, pushing the same into open the valve (not shown) of the faucet 23, and permitting oil to be sprayed upon the hog below. A yoke 45, through which the pole 34, extends is ,secured at 46, to the leg 31, whereby the pole is limited in its outer movement.

In order to control the extent to which the valve stem 44, may be operated to regulate the amount of spray to be emitted when the pole I4, is pushed in, I provide an adjustable stud bolt 41, having a nut 48, on its outer end 49, and a nut 53, on its inner end 5I, which end is adapted to engage the outer surface 52, of the leg 31, and thereby limit the in movement of the pole 34, thus a considerable, or a reduced, spray of oil may be ejected upon the hogs each time the pole is actuated by one of them.

The container I5, is provided with an air-tight cap 53, for its iilling port in the top wall 54. A pump 55, is also provided in said top whereby air i' may be pumped into the container to put the contents therein under pressure for a forced spray from the outlet of the faucet 31, when and if such a spray is required, otherwise just a few drops of the oil will fall upon the hog thereunder. The outer surface 56, of the pole 34, may be provided with serrations or prongs which will prove an invitation to the hogs (if they need one) to take a scratch thereon.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Changes in shape, size and rearrangement of details and parts such as come within the purview of the invention claimed may be resorted to, in actual practice, if desired.

Having now described my invention that which tank supported on the shelf and retained on the V shelf by the upper end portions of said uprights, said tank having an outlet port and valve controlling the now of liquid from the outlet port, a lever bar having upper and lower ends, a leg secured to the shelf and to the band, a hinge securing the lower end of said lever bar toksaid leg, means operatively connecting the upper end of said lever bar to the valve for actuation of the u valve by the lever bar, a substantially U-shaped guide and stop bracket having a web portion and spaced leg portions, the leg portions of said bracket being xed to said leg and disposed perpendicular to said leg with its web spaced from said leg, said lever bar being received between the leg portions of said bracket for pivotal movement with the web portion of said bracket limiting pivoted movement of the lever bar outwardly of the pole, the leg portions of said bracket also guiding the lever bar during its pivotal movement, a rod having first and second end portions, the first end portion of said rod being secured to said lever bar adjacent the upper end of said lever bar, said leg having an opening therein slidably receiving 'i the second end portion of said rod, a coil spring embracing said rod and biased between the levez` bar and said leg to yieldingly urge the lever bar against the web portion of said bracket, and means supported solely by said lever bar and disposed adjacent the upper end of said lever bar adapted to engage said leg during pivotal movement of said lever bar toward said leg to limit pivotal movement of said lever bar in one direction. i

2. A hog oiler comprising a support pole having upper and lower end portions, the lower end portion of said pole being driven into the ground, a shelf secured to the upper end portion of said pole, a band fixed to the pole and disposed adjacent the lower end portion of the pole, a plurality of circumferentially spaced uprights secured to the shelf and to the band, said uprights having upper end portions extending above the shelf, a tank supported on the shelf and retained on the shelf by the upper end portions of said uprights, said tank having an outlet port and valve controlling the flow of liquid from the outlet port, a lever bar having upper and lower ends, a leg secured t0 the shelf and to the band, a hinge securing the lower end of said lever bar to said leg, means operatively connecting the upper end of said lever bar to the valve for actuation of the valve by the lever bar, a substantially U-shaped guide and stop bracket having a web portion and spaced leg portions, the leg portions of said bracket being i'lxed to said leg and disposed perpendicular to said leg with its web spaced from said leg, said lever bar being received between the leg portions of said bracket for pivotal movement with the web portion of said bracket limiting pivoted movement of the lever bar outwardly of the pole, the leg portions of said bracket also guiding the lever bar during its pivotal movement, a rod having first and second end portions, the first end portion of said rod being secured to said lever bar adjacent the upper end of said lever bar, said leg having an opening therein slidably receiving the second end portion of said rod, a coil spring embracing said rod and biased between the lever bar and said leg to yieldingly urge the lever bar against the web portion of said bracket and a screw threaded stop member mounted on the lever bar and constituting a fastening means for securing said means on the lever bar.
