Abstract

400,755. Gate-operating mechanism. POTTER RAX GATE CO., Ltd., Shepperton Road, and COLEMAN, F. G., 104, Croydon Road, Anerley, both in London. Sept. 2, 1932, No. 24494. [Class 65 (i).] Mechanism for automatically closing a collapsable gate, shutter or the like comprises a lever, pivoted on an intermediate or forward upright of the gate and having a sliding rocking connection with another upright in the rear part of the gate or with some fixed support, and a spring-urged rod pivotally connected to a part of the lever extending beyond the sliding connection. The mechanism is shown applied to a lazy-tongs gate, in which the spring is enclosed in a cylinder A fixed to the rear upright J of the gate. A lever C is pivoted at L to an intermediate upright M of the gate, and its free end passes through a long slot in a member D fixed to the upright J and is pivotally connected to a rod B which is pulled downwards by the spring in the cylinder A to force the gate to the closed position shown ; the lever C has two pins F fixed in it to guide it while it slides up the slot in member D during opening of the gate. Preferably a second lever C<1> is provided, arranged symmetrically with the lever C on the pivot L and engaging in a similar way a member D<1> on a forward upright of the gate.
