Abstract

718,637. Hydaulic machines. CARBODIES, Ltd. Feb. 24, 1953 [April 24, 1952; Sept. 5, 1952; Jan. 26, 1953], Nos. 10289/52, 22330/52 and 2150/53. Class 69 (2). [Also in Group XXXVII] The drop-head frame member 21 of a motor vehicle is driven from an electric motor 25 through a telescopic device 27a which can either be a screw-type jack or a hydraulic piston and cylinder arrangement supplied by a hydraulic pump driven from the motor. An extension 22 of the frame operates limit switches 90, 91, for stopping the motor at the end of its travel in either direction. For raising the head, a pushrod is actuated to close the motor circuit, the push-rod being held in its operative position by means of a detent (see Group XXXVII). When the drop-head reaches the fully erected position, it closes the limit switch 90 to energize a solenoid for raising the detent and allowing the push-rod to be returned to the non-operated position. In a further arrangement involving the use of a motor-driven hydraulic pump, closure of a manual switch energizes the motor and a solenoid for a valve controlling the, supply of fluid to a cylinder forming part of the lifting and lowering apparatus. The operation of a relief valve, under the increased hydraulic pressure due to the drophead reaching an extreme position and resisting the effort of the hydraulic means, actuates a switch for energizing the winding which releases the detent; Figs. 11, 12 (not shown). In a modification, the apparatus for moving the drop-head is controlled by two solenoid-operated valves selectively energized by manual switches. The selected actuation of a manual switch energizes a self-maintaining relay for closing a circuit through the motor and through the winding of the appropriate solenoid-operated valve for actuating the hydraulic means in the desired direction. The operation of the relief valve at the end of the drop-head movement opens the circuit of the selected relay to de-energize the motor and the selected solenoid-operated valve. The switch controlled by the relief valve may be either of the normally-open or normally-closed type, Figs. 13, 14, 15 (not shown).
