A device for emptying refuse bins, having a tipping frame to engage the bin, a fluid-actuated motor connected to the tipping frame for moving it between a first position wherein it is capable of initial engagement with and holding of the bin, and a second, tilted position, wherein the bin is partially inverted, so as to empty the contents thereof into a larger, collecting container. A switch is provided, responsive to placement of the bin in position on the frame. The device further includes a control circuit having a timing device operated by the switch. The switch initiates operation of the timing device to direct the functioning of the fluid-actuated motor. In a preferred embodiment, the switch is mechanical and is adapted to be engaged by the walls of the refuse bin. Upon the expiration of a predetermined interval established by the timing device, power to the fluid-actuated motor is removed, and the tipping frame carrying the emptied bin is returned to its initial position.
A device for emptying refuse bins (1) into a collecting container (2), said device comprising in combination:
The invention as set forth in claim 11, and further including:
A device for emptying refuse bins into a collecting container, said device having two tipping frame (17a, 17b) adapted to hold two refuse bins, respectively and having two fluid-actuated motors (62a, 62b, 63a, 63b) respectively operating said frames and controlled by two valves in a hydraulic pressure source, said valves each being connected with an actuating mechanism, each of the latter being operated by a control circuit having a timing device regulating the opening and closing of the respective valve, characterized in that each of the control circuits contains a switch for initiating the control sequence, said switches being actuated when the refuse bin is placed on either tipping frame of the emptying device, and an additional valve (53) for selectively connecting the fluid-actuated motors in parallel and to the hydraulic pressure source (55) when it is desired that the frame operate in synchronism together.
