13,696. Nasmith, J. W. June 29. Signals, roadvehicle.- An adjustable pendent rod R carrying a wheel N is pivotany mounted in a bracket A attached to a vehicle axle so that when puncture of a tyre occurs the wheel N trails on the ground and carries the rod out of its vertical position. The pivot pin T, Fig. 3, attached to the rod projects into a box B cast on the bracket A and carries a notched disk K which by its rotation presses the springs G across the terminals of an electric circuit and rings a bell. As an alternative the wheel N may carry a ratchet-wheel which, in combination with a spring, indicates that the wheel has touched the ground.
