Title: Improvements in fuel consumption meters for motor vehicles, motor-boats and liquid fuel engines
IPC: G01F23/34
Filed: 1922-06-29
Abstract: 204,145. Rippingille, F. S. June 29, 1922. Measuring consumption of petrol with respect to speed of engines &c.-The fuel consumption of an internal-combustion engine, say, of a motor vehicle is measured by means of a float chamber adapted to be placed in communication first with the air tank for filing and then with the carburetter for the test. The vehicle is then run over a measured distance and the amount of fuel consumed is shown bv a pointer connected with the float and indicating on a dial graduated in terms of miles per gallon. In one form shown in Fig. 5, the float 7 of the meter i is mounted between arms fixed to a spindle 11 geared as shown with the pointer spindle 14. A multiple way cock 16 permits flow from the main tank through pipe 2 either into the chamber or direct to the carburetter by way of pipe 6, and may also be turned to allow or prevent flow from the chamber to the carburetter. The connection between the float and pointer may take the form of rack and pinion, bevel or toothed arc and pinion gearing. In the modification shown in Fig. 7 the pointer spindle is actuated through gearing 13, 26 by a rotatable partially toothed annulus 12 carrying the float 7. The annulus may be weighted so as to cause the float to pass beyond the dead centre when the chamber empties so that when it i, again being filled the float rises on the other side and in so doing does not drive the pointer. Both the inlet 2 and the outlet 28 are controlled bv automatically-actuated valves 29, 30, the inlet valve 29 being opened by a spring-pressed lever 31 as soon as the chamber is emptied and closing when it is filled, and the outlet valve 30 being opened by a second spring lever 32, likewise operated by a cam 33 in the toothed annulus, when the chamber is filled. In this way a continuous filling and emptying of the chamber into the usual intermediate constant-level supply vessel 34, Fig. 8 takes place during the running of the engine, but to enable the consumption over a measured mile to be determined there is a pipe 36 from the meter 1 to the carburetter 35, and a three-way cock 37 upon the engine side of the intermediate vessel 34 to provide for a direct supply from the meter. A counter may be actuated by the float so as to register total consumption over a journey or period.
