Abstract
794,309. Speed-responsive switches; switch cases. GAYLORD PRODUCTS, Inc. June 21, 1956, No. 19243/56. Class 38 (5). A switch suitable for detecting unintended movement of a motor vehicle, comprises an insulating cup-shaped member 1 containing a non-conductive liquid 7 and having a metal disc 4 which is normally engaged by a conducting vane 25 pivoted on a screw 24 threaded into a rotatable element 20. The latter is traversed by a speedometer cable 28 and also clamped thereto by a friction member 30 which grips the inner enlarged bore 27 of element 20. The cable-sheath ends 31, 32 are secured in split collars 9, 16 on the member 1 and closure 13 thereof and the whole secured to a support 33 having pairs of clamping arms 38, 39 and 40, 41 urged against the collars by bolts (Fig. 1, not shown). In operation, the liquid 7 acts on the rotating vane 25 to pivot it about screw 24 and disengage the plate 4, so breaking the circuit between lead 6 and earth 46.
