all original and fully functional early 20th century antique american industrial cast iron pig or hog oiler device manufactured by farm-master inc., shenandoah, ia. the earliest design patent was issued to george j. saffert of new ulm, mn. in 1913. the dual oil delivering rotary wheels are comprised of sectional pierced cast iron that rotate freely above the detachable oil reservoir. 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. the hog oiler has been brushed down to bare metal and sealed with a clear coat lacquer. measures 11 x 11 x 11 1/2 inches.
