Abstract: 147,722. Ohmer, J. F., and Ohmer, F. L. May 21,1917, [Convention date]. Speed indicators with distanceregisters. - The apparatus described is practically identical with that described in Specification 147,721. The printing- mechanism however instead of co-operating with means governiug the operative and inoperative condition of the ignition system of the motor controls the admission valve through which the motive fluid is supplied to the carburettor of the engine. The invention is shown applied to an engine utilizing combustible fluid. The driver of the vehicle carries an identification key which is adapted to unlock the recording-mechanism, and an actuation thereof through gearing 89, 90, Fig. 4, having the ratio of 1 to 2, effects the rotation of a cam 99 attached to the wheel 90 through half a revolution. An arm 98 carrying a roller 101, which is held in engagement with the cam by means of a spring 100, follows the movement of the cam and by means of a pin 119 thereon engaging a slot in one end of a lever 114, Fig. 5, rocks said lever so that its other end which is connected to an arm 115 of the valve 116 opens the valve to the source of supply. The next succeeding operation of the printing mechanism closes the valve, releases the identification key so that it can be withdrawn from its housing and thereby locks the printing- mechanism. In a modification the arm 98 may act directly on an extension rod attached to the arm 115.
