Abstract
1,220,903. Caps for pit props. HERMAN HEMSCHEIDT MASCHINENFABRIK. 28 Aug., 1969 [29 Aug., 1968], No. 42962/69. Heading E1P. A cardan type joint between a roof lining beam and a prop head, comprises a mounting 3 having a swivel pin 12 pivotally secured on the beam so as to permit the mounting to swivel in a direction transversely of the beam, and having also forked elements 5, 6, which are pivotally connected to the prop head to permit pivotal movement between the beam and prop head longitudinally of the beam. The mounting has an undersurface which engages a roller-like top surface on the prop head and the upper surface of the integral swivel pin engages in a groove 11 in the beam, the ends of the pin being rotatably secured in lugs 16 (fig. 3) attached to the beam. Abutment surfaces 19, 20 and 17, 18 (fig. 2) limit the extent of possible pivotal movement in the transverse and longitudinal directions respectively.
