A Centrifugal-electric Governor

T°govern speed by a device driven from the transmission, which automatically cuts out the engine when the predetermined limit is reached, is no new idea, and is viewed with somewhat mixed feelings. Whilst it is held in some quarters that an inability to accelerate may constitute a danger, in
others efforts have actually been made to render compulsory the use of such a device.
Many operators, however, are in favour of thus controlling the vehicles in their service, and, consequently, there should be a market for an apparatus that is to be made by R. A. Rothermel, Ltd., Canterbury Road. Kilburn, London, N.W.6, and that is shown in the accompanying drawing.
' Its essential feature is a centrifugally operated switch, and the device is intended to be connected in the speedometer drive, the cable being broken for that purpose. The governor is mounted on a countershaft, which transmits the drive, via fibre and metal pinions, to the speedometer, and the switch is normally closed and is connected in the ignition circuit, which is interrupted when the governor weights fly apart.
A noteworthy point is that the entire length of the electric cable can be enclosed in armoured conduit, and, if necessary, sealed to render it impossible for the two wires to be connected together, and the switch, in this way, short-circuited. We understand that the device will be offered at a moderate figure.
