Abstract

1409137 Gate operating devices L D ROYSTON 26 Jan 1973 [21 Sept 1972] 4156/73 Heading E2M In a gate opening device a detector, in the form of one or more vehicle operated mats 20a, 20b each incorporating a master cylinder 22, is actuated when a certain weight is applied to the detector, slave cylinders 16a, 16b being connected to a gate 12a, 12b respectively and adapted to be actuated to cause the gates to open when the detector and its associated master cylinder are depressed. On release of the pressure on the mat gate springs return the gate arms 12a, 12b to their closed position. The hydraulic circuit can also actuate a latching device 18 operated by a slave cylinder 19 in the hydraulic circuit to permit the opening of the gate arms and a detent is provided to prevent the opening of the arms. A holding or delay device (32) (Fig. 5, not shown) is incorporated in the mechanism for holding the gate open for a short period when the actuating device which opens the gate 6 is deactuated.
