MIXTURE CONTROLLING VALVE.-Albion Motor Car Co. Ltd. and T. Blackwood Murray.-No. 6,903, dated 20th March, 1911.-The valve de scribed in this specification is arranged to give a simultaneous control of both the air and the mixture passages by a single lift valve. The mixture enters by the upper passage on the right-hand side into an annular space, and passes downwards through ports in the diaphragm to the second annular space into which air is admitted by a lateral conduit not shown in this view. The conical valve below this second annular chamber controls the passage of the mixture to the engine. The by-pass or pilot valve may be arranged axially on the main valve in accordance with Patent No. 15,584 of 1910. The inlet port for this pilot valve is shown in the spindle and connected with the upper annular chamber.
CHAIN CASE.-Albion Motor Car Co. and Murray.-No. 24,073, dated 18th October, 1910.-The chain case described in this specification is arranged to obviate the difficulties hitherto encountered due to lateral motion of the back axle and to the use of the small bush which prevented suitable lubrication and stiffness. A concentric double conical journal of somewhat large diameter is provided on the axle bush and on a plate forming an integral part of the chain ease a similar double conical collar is provided; between these conical parts a packing of leather or other suitable substance is provided. Either the collar or the journal is split and means are provided for adjusting the parts relatively to one another. The plate on which these conical collars are provided is attached to the rest of the chain case by the equivalent of a stiff
hinge. Narrow flanges are provided on the plate and on the adjacent part of the chain casing, and a packing of compreesible material is inserted between the parts which are held together by a single row of bolts passing through the flanges.
SLEEVE VALVES,—D. M. White and D. Napier and Son, Ltd.—No. 28,372, dated 6th December, 1910.—This invention relates to explosion engines in which separate inlet and exhaust valves of the sleeve type are provided. The valve chambers are arranged on either
side of the working cylinder ; that on the left for the inlet is smaller than the one on the right for the exhaust. The valves may be of an oscillating, rotating or reciprocating type, and are actuated by any suitable means from secondary shafts.
CARBURETTER. Lamplough, No. 17,343, dated 21st July, 1910.-In this specification there is described a carburetter in which the mixture is made to pass downwards to the inlet ports, thereby rendering it especially applicable for use with heavy hydrocarbons. The body of the carburetter is cloeed at the top by a conical pipe from which the air passes inwards by inclined passages to impinge on the fuel nozzle. The mixture passes downwards past an inverted done and escapes by means of helical passages formed on the outside of the conical surface of the stop valve. Before passing tn the inlet passages to the cylinders
the mixture is made to pass through an annular perforated screen ; the mixture enters from each side and
passes downwards between the two per
forated plates. An auxiliary air inlet is provided round the main air inlet and is controlled by a vertically-moving tube which also forms a throttle for the mixture.
WHEEL. Brampton. No. 5,367, dated 3rd March, 1911.-This invention relates to hubs suitable for road wheels for vehicles, pulleys or the like, and refers to that class in which the rim is secured to the hub by means of hollow spokes. In the hub, annular holes are made for the reception of the spokes, which preferably are flanged at the inner end, The upstanding part of the hub inside the spoke is riveted over to secure the spoke in place. In an alternative construction the upstanding part is made smaller and a ferrule is inserted round it, the two together then being expanded or riveted over. This ferrule is preferably bored slightly taper or has a coned mouth or enlargement at the outer end. For convenience in expanding the central rivet, it is bored out with a vertical hole in the upper surface. The outer ends of the spokes are secured to the rim by cutting them open to form suitable ears which are attached by riveting or any other convenient means.
