Abstract
858,464. Lifting-jacks; load-engaging devices for handing loads. KELLY, J. J. May 5, 1958 [July 22, 1957], No. 14367/58. Classes 78 (3) and 78 (4). [Also in Group XXIII] A device 40 for automatically gripping a car engine is pivotally mounted on parallel pivoted links 16, 21 of a wheeled jack and comprises a frame 41 pivoted to links 16 at 19 and carrying two pairs of parallel tubular sockets 50 pivoted about axes 46 and urged to an upwardlyinclined position shown in chain lines, Fig. 4, by springs 49. The links 16, 21 are raised by rotating a screw 31 which engages a nut (not shown) supported on a cross-member between links 21. In operation, the device 40 is raised until the inner ends of sockets, 50, engage in grooves 58 in the engine E, Fig. 4, and embrace heads of bolts 59 after overcoming the action of springs 49. Pins 54 are passed through the frame 41 into tubular members 51 secured to the sockets 50 to lock the sockets when they have engaged the bolt heads 59.
