Patents, Hog oiler
A hog oiler was a mechanical device employed on farms to be used by hogs to provide relief from insects and offer skin protection. It consisted of a reservoir to hold oil, and a means to distribute the oil onto the hog, often via grooved wheels or cylinders. Hogs seeking relief would rub up against a wheel (or cylinder) causing it to rotate and dispense oil onto their bodies.
Hog oilers were produced in a variety of designs, most made of cast iron. The era of innovation for this device was mainly the years 1913-1923; during this time some 20 patents were issued by the U.S. Patent Office.
Hog oilers are now considered desirable antiques by collectors of agricultural equipment.
