Filed: 1927-02-22
Abstract: 286,445. Taylor, H. B. Feb. 22, 1927. Cylinders receiving liquid fuel. - To prevent a fuelinjection valve, actuated by the fluid-pressure of the fuel, from opening too suddenly, the valve is arranged to strike a loaded stop after a small initial opening of the valve. The valve 1 is loaded by a light spring 10 and opened by the pressure of the fuel admitted at 7 and acting on a flange 27, an air vent 8 being provided. The stop 2 is loaded by a strong spring 12 the pressure of which may be adjusted by rotation of a screwed sleeve nut 18 locked by a nut 18<1>. The clearance between the valve and stop can be adjusted by screwing the stop into a sleeve 15, the stop being locked by an arm 27. The amount of the total opening of the valve is limited by a flange 20 which contacts with a cover 13, adjustable in the casing by a screw-thread 22. A fuel-leakage drain 28 is provided. In a modification, the valve is loaded by a semi-elliptic leaf-spring, the load of which is adjustable by screws engaging the anchoring shackles, and the stop is loaded by a pair of beams the pressure of which is adjusted by cams on one of the end-carrying members. The beams engage the stop through a flanged nut.

Title: Improvements in lighting appliances
IPC: F21V5/00
Filed: 1926-02-25
Abstract: 258,482. Stephens, A. J., (Rolph, T. W., and Dorey, W. A.). Feb. 25, 1926. Lantern fronts.-One surface of the front glass of a vehicle, signal, street or like lamp, adapted to illuminate a relatively long rectangular area, is provided with light-directing surfaces adapted to refract light downwards and outwards, these surfaces being separated wherever they occur by corrugated spaces. In the form shown in Fig. 5, a light source 10 is placed slightly above the focus of an ordinary condensing lens 11 having a, smooth inner surface 12 and annular prisms 13 on its outer surface, and the cover gla.ss 15 has its inner surface covered with diagonal lattices 18, 19 separated by smooth spaces 21 and its outer surface covered with laterally-spreading vertical flutes 17. Alternatively, the outer surface of the cover glass may be left smooth and the vertical flutes 17 made between groups of diagonal lattices 18, 19 arranged at different angles and intersecting each other on its inner surface, as shown in Fig. 3. Fig. 6 shows another form, more particularly for use with a parabolic reflector, in which the light is refracted downwards and outwards across the axis of the lamp by means of diagonal lattices 18, 19 of constant width but with inclination to the horizontal and their transverse concave curvature increasing progressively towards the bottom. Alternatively, the diagonal lattices may be of constant transverse curvature, in which case their width and inclination to the horizontal increases progressively towards the top. If the lattices of these two latter forms are made convex and the arrangement turned upside down, the light is refracted downwards and outwards away from the axis of the lamp. If the lamp be placed at the corner of the area to be illuminated, only one set of diagonal lattices is required for example, as shown in Fig. 9 in which diagonal lattices 18 are located in the upper left hand corner of the cover glass of a ditch light to refract light downwards and to the right, the diagonal lattices being intersected by horizontal depressing prisms 22. Fig. 10 shows a still further form using downwardly curved and preferably small prisms 24 the active faces of which may be spherical. The inside contours of these prisms are arcs of a circle but their depth increases from the centre outwards, this curvature being obtained by originally making the prisms of constant depth and cutting out vertical flutes 25 with their full depth corresponding to the centres of the prisms. Alternatively, upwardly curved prisms may be used, or upwardly and downwadly curved prisms may be arranged alternately in wave-like form horizontally or diagonally across the face of the cover glass. When the lamp is placed at one corner of the area to be illuminate ,d half prisms only are used.

Abstract: 631,727. Surface carburetters. MEYNIER, J. M. J. F. Feb. 26, 1946, No. 5988. Convention date, Aug. 7, 1939. [Class 7 (iii)] The carburetter comprises a member of china or like porous material a vertically arranged central cylindrical chamber enclosed in the porous member an annular chamber enclosed within the porous member and surrounding the central cylindrical chamber the annular chamber being supplied with fuel through the lower part thereof and a regulating member comprising a sleeve of smaller diameter than that of the central chamber the sleeve being closed at its lower part by a plug in such manner as to permit flow of air through the annular space between the outer surface of the sleeve and the inner surface of the central chamber the sleeve also being provided with a return spring and adapted to slide longitudinally within the central chamber under the combined control of the suction of the engine and the elastic force of the spring so as to effect automatic variation of the mixture strength by the movement of the sleeve relative to the porous element. As shown liquid fuel is supplied from a reservoir, by a pipe 24 to an annular chamber 12 in an element 8 of porous material such as china. Air for slow running is drawn by engine suction through holes 2 and passes around the outside of the element between it and a casing 1 the air carrying with it sufficient fuel for slow running. The main air supply enters through holes 5 and a valve 15 which is opened by engine suction, and passes through an annular passage between a sleeve 14 attached to the valve 15 and the walls of a central bore 13 in the element 8. The mixture so formed together with fuel air mixture from around the outside of the element 8 passes to the engine past a throttle valve 23. A pipe 12a normally open at 12b admits air to prevent fuel from being drawn further up the chamber 12 under engine suction through its wall 9. The carburetter may be readily designed to cater for different requirements of mixture richness, the weight of the sleeve 14, and valve 15, the elasticity of the spring 20, loading the valve 15, the length and diameter of the sleeve 14 and the internal diameter of the inner porous element 9 affecting the mixture richness.
