Abstract

727,788. Load-handling machines. OELLRICH, A., [trading as MASCHINENFABRIK UND EISENGIESSEREI A. BEIEN]. Dec. 16, 1953 [Jan. 16; 1953], No. 35070/53. Class 78 (3). In a loading machine in which one motor propels and another operates a scoop, the motors are operable by pressure fluid circulated by at least one pump continuously in one direction through one ring conduit to which the motors are connected through control and change over elements. A bucket loading machine is mounted to move on rails and is rotatable about a vertical axis and discharges into a truck at the rear. An oil reservoir 10 is mounted on skids and carries an electric motor 15 operating a pump 14 through a clutch 16. The pump is connected to a safety valve 29 and by a hose 18 and pipe 19 to control boxes 20, 21 connected to motors 7 and 8. The control boxes have a manuallyoperated gear-wheel 31 meshing with an axially movable sliding valve member 32. When the handle is central, Fig. 4, no fluid flows to the motor. Fluid flows from the pipe 19 to an annular groove 37 connected by a channel 38 to the return pipe 36. When the handle is turned to the left, fluid flows down pipe 24 to the motor and is discharged through pipe 25 to the return pipe 26 through the duct 36 in the slide valve. When the handle is turned to the right fluid flows through a cross-channel 39 to the groove 37 to the pipe 25 to the motor and returns by pipe 24 and duct 36 to the return pipe 26. The amount of pressure fluid can be controlled by partially opening the ports or groove. Two pumps may be used instead of one.
