Hog Oilers Were Cheap Insurance

Stockmen turned to hog oilers to battle vermin and disease

C.W. Sherman's Stock Rubbing Device
C.W. Sherman’s Stock Rubbing Device, manufactured in Peoria, Ill., used grease rather than oil. Grease was worked through the gears, and then paddles forced it down to the device’s wheels. The big wheel, controlled by a ratchet, would turn in one direction only; the small red wheel at left is a belly oiler.
