A refuse compactor having structure for preventing displacement of the compactor receptacle beyond a preselected permissible displacement during the compacting operation. The control includes a tilt switch for terminating operation of the compacting ram in the event of a preselected tilt movement of the receptacle during the compacting operation. The control further includes a safety switch preventing operation of the ram when the receptacle is displaced beyond a preselected distance from the compacting position. The displacement limiting structure disclosed herein is carried by the ram so as to be operative during the compacting operation to prevent a movement of the receptacle substantially beyond that effecting an opening of the tilt switch. The ram may be provided with a wiper which may form a portion of the displacement limiting structure.
In a refuse compactor having a receptacle for holding refuse to be compacted, electrically operated compacting means for compacting refuse in the receptacle with the receptacle disposed in a compacting position, first switch means for interrupting operation of the compacting means in the event the receptacle is displaced a first preselected distance from the compacting position by the compacting means during a refuse compacting operation, and second switch means for preventing operation of the compacting means in the event the receptacle is disposed at least a second preselected distance greater than said first distance from the compacting position, the improvement comprising
In a refuse compactor having a support, a ram, a receptacle into which refuse is placed to be compacted, said receptacle being movably carried on said support for selective disposition in a refuse compacting position in alignment with the ram and in an exposed refuse loading position, electrically operable drive means for selectively driving the ram into the receptacle to effect a compacting operation, and control means for controlling operation of the drive means including a tilt switch, a receptacle safety switch and a manually operable start switch, said tilt switch being positioned to open upon a preselected first small displacement of the receptacle from said compacting position, said receptacle safety switch being positioned to open upon a preselected second displacement of the receptacle from said compacting position greater than said first small displacement, said start switch being connected to the drive means to permit re-energization of the drive means subsequent to a stopping of the drive means as a result of said receptacle being displaced at least said first displacement from said compacting position during the compacting operation, the improvement comprising
