Details of the Lyon-Spencer Gas Control Valve and Carburetter.
A new filling and connecting valve for itse with coal-gas has been designed by nasal>, Ernest Lyon (Gas Equipment) Ltd., for uzs in connection with the Lyon-Spencer coal-gas supply from flexible containers to internal-combustion engines.
The body of the valve is cast in aluminium,. and consists of a tapered barrel came,with a tapered', rotary aalve, the fatter haying ports cut in it so that gas can be. passed through it from the source of supply into the flexible gas container fitted on the car, duringi which process the port leading to the pipe which feeds the engine will be cut off. The second function of the device ia to supply the engine from the flexible gas container, the port for connecting up to the source of supply being then closed. The device is extremely simple, and we show it by photographs and by a sectional drawing.
From the photograph, it will be seen that, by means of a hand lever, the • valve can be set at the three positions : one for charging, one for wily to the _ engine, and one when all orifices are closed. The perforated pipe goes inside the flexible gas container, which is secured round the neck of the pipe above the flange. The bent pipe'is bolted, by its flanges, to the flanges at the top of the gas valve, clamping the bottom of the tray between the two flanges. Referring to the sectional drawing, 'it will be seen that the gas onters'at the bottom _ by a two-inch orifice (A), and has a clear run through into the as container. Whilst the process of filling the container is going on, the supply orifice (B) is shut off. When the container is fullr charged, the, act of rotating the barrel valve to the left r45 degrees from the charging position closes the charging orifice,' the orifice (B) remaining closed; if rotated to the right_ it. opens a port leading to the supply pipe (B), and leaves the charging orifice (A) closed.
The valve is adapted. to be pressed against the casing' by a spring which is mounted on the valve spindle. The filling orifice (A) is adapted to take, by means of two baprtet catches, a tapered adapter forming a gas-tight joint. This can be fastened to the ordinary supply pipe from the gas meter, It provides a ready means of attachment and detachment. The whole apparatus is exceedingly neat and workmanlike.
Lyon-Spencer Gas Carburetter.
Messrs. Ernest Lyon (Gas Equipment), Ltd., have also produced a new carburetter adapted for mixing coal-gas and air. This also is illustrated by photo

brings the gas to a central gas jet, which is capable of being regulated in its effective diameter by a conical, ping mounted at the end of a. screwed stem, the latter having a milled nut' tolock it into position. By means of this conical plug the throat of the gas Inlet can from the outside be enlarged or reduced, as required, when the carburetter is being set and adjusted to suit the engine to which it is being fitted.
A screen is placed across the annular chamber between the gas duct and the conical gas. jet,. in order to preyent hack-firing" IMO the spare° of supply. The body ofy.the carburetter i.proided with a rotary sleeve with ports in the shape of staggered hales, each gniup , being set at a slight angle, which are uncovered on the inside by vortical ports The new gas filling and connecting formed in the easing. By means of valve, showing_ bayonet socket to . a worm thread on the edge, the amount igCeive adapter. of -air passing into the engine can be
adjusted to the engine's requirements, so that both air and gas by the means described can be adjusted and regulated to a very fine degree. The supply of the mixture is controlled by a butterfly valve in the upper part orthe body.
Provision has been made for the fitting of liquid fuel jets at the base of the annular chamber below the coned throat, but it is generally, found that vehicle owners prefer to leave the carburetter already fitted to the car in' situ, regarding the addition of a. gas carburetter as' the most economical way of fitting up vehicles to run on alternative fuels.
