Abstract
Abstract An improved garbage truck is disclosed having an inlet opening leading into a tipping section, where a press reciprocally moves in the tipping section, guided along the side walls thereof, to propel garbage through an opening into a removable container. The tipping section has at least one lateral arm or wall reinforcing the side walls of the tipping section and is arranged above the press. A sensing element is arranged in the tipping section with generates a signal when there is a jam or when there are tilted or bulky objects, the signal stops the travel of the press or reverses the direction of the press to prevent damage to the garbage truck.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
176 words
A garbage truck comprising: a garbage inlet opening leading into a tipping section having side walls, an upper section, and an open push-out side; means for pressing in a reciprocally moveable motion in the tipping section, said pressing means having an upper edge and being guided along the side walls and propelling discharged garbage through a receptacle inlet opening into a removable receptacle; at least one lateral member reinforcing the side walls of the tipping section and being arranged above the press means; a shaft pivotally mounted in the upper section of the tipping section in close proximity to both the receptacle inlet opening and the upper edge of the press means, said shaft having a claw means for pressing down and freeing objects seized by the press means; means for pivoting said shaft and activating said claw means when objects are seized by the press means; a sensing element integrally associated with the shaft, the sensing element generating a signal when there is an obstruction, said signal stopping the reciprocal movement of the press means.
Claim 2
Dependent Claim
176 words
A garbage truck comprising: a garbage inlet opening leading into a tipping section having side walls, an upper section, and an open push-out side; means for pressing in a reciprocally moveable motion in the tipping section, said pressing means having an upper edge and being guided along the side walls and propelling discharged garbage through a receptacle inlet opening into a removable receptacle; at least one lateral member reinforcing the side walls of the tipping section and being arranged above the press means; a shaft pivotally mounted in the upper section of the tipping section in close proximity to both the receptacle inlet opening and the upper edge of the press means, said shaft having a claw means for pressing down and freeing objects seized by the press means; means for pivoting said shaft and activating said claw means when objects are seized by the press means; a sensing element integrally associated with the shaft, the sensing element generating a signal when there is an obstruction, said signal stopping the reciprocal movement of the press means.
