Abstract
342,975. Operating sliding gates. DARBY, J. H., Newton House, Newton, Rugby. May 16, 1930, No. 15056. Addition to 321,623, [Class 65 (i), Door and gate operating appliances &c.]. [Class 65 (i).] In apparatus for operating sliding gates by tilting the rails on which they run by .means of treadles, similar to that described in the parent Specification, the treadles 9, 10 are pivoted at the ends remote from the gates 1, 2, and their other ends are carried by a pair of levers 16 pivoted at 17. The levers are normally held by a detent 22, so that the gates cannot be moved until one of the trips 25,27 has been operated, as by an approaching vehicle, to release the detent. When one of the treadles is then depressed, the end 19 of the pair of levers raises the inner ends of the tracks 5, 6 on which the gates run, so that the gates open by gravity. When the treadles are released, the weight returns the apparatus to the normal position, and the gates run down the tracks and close.
