Device for emptying containers, especially refuse bins
First Claim
1. A device for emptying refuse bins (1) into a collecting container (2), said device comprising in combination:
- (a) a tipping frame (6) for holding a refuse bin (1), said tipping frame being movable between a first, bin-receiving position and a second, bin-emptying position,(b) a source (33) of pressurized fluid,(c) a fluid-actuated motor (9) for shifting said tipping frame between said first and second positions,(d) valve means (36) connected with said source (33) of pressurized fluid and said fluid-actuated motor (9), for controlling the shifting movement of the tipping frame (6) between said first and second positions, by the fluid-actuated motor (9),(e) said valve means (36) comprising an actuating mechanism,(f) a timer (45), for controlling the actuating mechanism of the valve means (36),(g) switch means (12) responsive to placement of a refuse bin (1) on the tipping frame (6), for automatically initiating operation of the timer (45),(h) said timer (45) being characterized by a predetermined timing interval, said interval being at least sufficiently long to enable the fluid-actuated motor (9) to shift the tipping frame (6) from its first position to its second position after operation of the timer (45) is initiated by the switch means (12),(i) said timer (45), upon expiration of said timing interval, effecting movement of the actuating mechanism of the valve means (36) to a position causing said tipping frame (6) to return to its first, bin-receiving position.

Abstract
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.

- 13. 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.
