Abstract
463,509. Fencing; gates. BELSHER, B. J. Feb. 26, 1936, No. 5730. [Class 45] Pedestrian barriers, cattle pens, and like fence-like structures are provided with means to facilitate making a temporary gap. The gap is normally closed by chains b, c, divided in the middle and having the ends united by bars d, e, adapted to be secured together. When the bars are separated, the surplus chain is drawn inside the standards a, which are hollow, by weights f. The chains pass over pulleys g or the equivalent, and the weight is channelled to accommodate the lower chain c. The posts may be provided with drain holes h, and hand holes for lifting, which may be covered by loose rings k. A rubber &c. buffer l may take the impact of the weight. Hoods g<1> minimize the entry of water and a stop bolt j limits the upward movement of the weight. The bars d, e are provided with handles d<2>, e<2> and are formed with lugs d<1>, e<1> to engage each other with a sliding movement, being locked in the closed position by a screw bolt i, Fig. 7. The withdrawal of the chains may be caused by spring action.
