Dempster Dumpmaster

The Dempster Dumpmaster, introduced in the 1950s, was the first commercially successful, front-loading garbage truck in the United States. The product uses the ''Dempster-Dumpster'' system of mechanically emptying standardized 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-traveling 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.
