Abstract

3892. Wolseley Tool and Motor Car Co., Remington, A. A., and Rowledge, A. J. Feb. 16. Spray carburettors.-The flow of fuel from the float chamber to the multiple nozzle B is controlled by restricted orifices c' in tubes c, which can be easily removed for cleaning. The spraying - nozzle comprises a plate D, Fig. 4, held between a ring D<1> and the part B, and having two series of slots d', d<2> fed by two independent annular conduits b<1> supplied by passages b<2>, b<3>, b<4> and spraying into air passages a, d, which are immediately connected with a common carburetting - chamber. In another form, the plate D may be omitted, the fuel passing through vertical holes in the ring D<1>. The passage a may be cut off by the choke tube h for slow running. The throttle valve E, has a by-pass f<1> for slow running, and is connected to the choke-tube by a spindle J and spring j, so that the throttle may be opened slightly before any movement of the choke-tube takes place. When the throttle is raised considerably, supplementary air is admitted through the ports g, e. In a modification, a supplementary supply of fuel is admitted to the outer conduit b<1> by a needle valve which is opened when the throttle is nearly fully open.
