ROVISIONAL patent rights have been obtained by Mr. J. A. Harrop, 42, Woodcock Street, Sandal, Wakefield, and by Mr. M. W. Robinson, in respect of a speed-governing device which, in addition, serves as g recorder, the ribbon or chart of which is visible. It also functions as a speedometer.
The operator of the vehicle can select the maximum speed which he wishes to be attained; this can be varied to suit conditions. A mechanical drive is taken from the transmission or wheels in the usual manner adopted for a speedometer. When the vehicle reaches the pre-determined maximum speed, Ina electric contact is made which completes a circuit and operates a mechanism for retarding or discontinuing the supply of fuel. Shortly before the maximum speed is attained, another connection is made, and a coloured light warns the driver that he is nearing the limit set.
In conjunction with this device there is a recording ribbon, or diagram chart, which, tieing geared directly or indirectly to the road wheels of the vehicle, moves through a definite space for a given distatce travelled along the road. In this way a complete record of speed is obtained for any journey. Precautions have been taken to avoid tampering. Any person interested in this device should correspond with Mr. Harrop. 1341
