Dempster Dumpmaster

From Wikipedia, the free encyclopedia

The Dempster Dumpmaster, introduced in the 1950s was the first commercially successful front loading garbage truck.

Built by Dempster Brothers, Inc of Knoxville, Tennessee, they used the Dempster-Dumpster system of mechanically emptying standardised metal containers, which had been patented by the company in 1937. It had arms at the front that picked up a dumpster and lifted it over the cab to tip it into the hopper. A rearward travelling compacting panel compressed the garbage stored in the truck, and was also used to push it out through a door at the back when it was being emptied.
