Abstract
581,833. Hydraulic machines. DOWTY EQUIPMENT, Ltd., DOWTY, G. H., and BASTOW, F. Feb. 25, 1944, No. 7546/45. Divided out of 579,294. [Class 69 (ii)] In a locking device for telescopic jacks of the kind in which spring fingers 10 on the piston or cylinder engage a locking-formation 12 on the other member and are locked in position by a sleeve 13, the sleeve is urged into locking 'position by fluid pressure. Specifications 568,582 and 579,294 are referred to.
