Abstract

454,180. Breaking - down appliances for mines &c. GULLICK, Ltd., 3, King Street, Wigan, and SEAMAN, T., 153, Twentywell Lane, Dore, Sheffield. May 29, 1935, No. 15587. [Class 68 (i)] In a hydraulic breaking-down appliance for mines &c., comprising a body 10 with one or more cylinders 11 each containing a ram 12, the rams are of full cylinder diameter with a flat 15, or opposed flats, terminating in a shoulder 16, each flat being engaged by a transverse bar 18 forced into an aperture 17 to limit the stroke of the ram. The ends of the bars 18 are chamfered to the contour of the body 10. In another form, the bars 18 are arranged longitudinally of the body and are common to all the cylinders. In other forms, the bars are screwed into the body or the apertures therefor extend inwardly from one side of the body only. In Fig. 6, a telescopic ram is provided, the outer ram member 24 being retained by bars 27 and carrying bars 30 for retaining the inner ram member 26.
