No. 17,o78., dated August 4th, 3904 J. Cairn, Ireland.—This patent is for a pneumatic foot device for sounding a horn on a motor vehicle. Within a suitable casing (a), supported by a strap (j), is a bellows (c) normally maintained in an extended state by a spring (d). At the top of the bellows (c) is a plate (c1)1 having an upwardly-extending rod (h), provided with a foot plate (i). The casing (a) is situated beneath the foot-board (1), and when the foot plate (1) is depressed, air is forced from the bellows through the outlet conduit (n), which communicates with the horn or any other alarm device, so that the latter is sounded. The chamber (a) is provided with an inlet valve (e), for the admission of air.
No. 18,713, dated August 3oth, 1904 : P. W. Noble, Swindon.—In order that the various parts of a motor vehicle may be readily assembled on the vehicle frame, a standard frame (a) is provided according to this invention. Each vehicle of the same type has a frame of the same kind, and a corresponding frame is kept at the works, so that all the parts of the vehicle may be assembled and aligned upon it before putting them into the vehicle. The frame comprises a longitudinal member of T-shaped cross section, as shown in Fig. 2, which is a section on the line 2.2 of Fig. i Fig. 3 is an underside view. The forward part of the frame is extended for carrying the en gine, which may be secured to it by bolts passing through the holes (A1). Lugs (DI are situated underneath the frame for carrying the silencer, and other lugs may be provided for the carburetter or ignition apparatus, etc. The lower part (B) is to provide clearance for the fly-wheel and clutch, whilst the part C carries the gear box. By connecting the engine and the gear box and intermediate parts directly to this rigid member, it will be seen that they are always in correct alignment if properly adjusted in the first instance.
No. 17,047: dated August 4th, T904-F. W. Lanchester, of Erighaston, Birmingham.—This invention consists in governing an internal combustion engine by the action on the throttle or like valve of a hydraulic ram or its equivalent actuated by a pump driven from the engine and provided with an adjustable leak or by-pass. A spindle (I) driven by the motor carries an eccentric (j), which reciprocates a plunger (a) in a cylinder (b) mounted within a bath (e), from which the pump can draw its supply of oil through groove (ci). The pump delivers through passage (c2) to the underside of a ram (d), arranged to act on the throttle valve through bell crank (e) and rod (f). A spring or weight which may act directly on the ram (d), as indicated by arrow (g), is arranged to hold said valve open and to exercise an approximately constant pressure on the fluid under the ram (4) when the engine is at work. A needle valve (h), having a milled head (ill), is employed to control a leak or bypass by which oil is allowed to overflow from the delivery side of the pump and so pass back into the well (c). The speed of the engine is practically proportionate to the area of the leak aperture.
No. 7,078: dated April 4th, r9o5.—Albion Motor Car Co., Ltd., and Murray, of Scotstoun, N.B.—This invention relates to a mechanical feed lubricator. This lubricator comprises a rectangular
box (A). A central stud (B) extends up into the container (A) and carries a disc (131, machined on its upper surface and fixed clear of the bottom by studs (}32) on its underside, resting in depressions in the bottom, so that the lubricant has access to the space beneath this disc (131). Ports (B3) are formed through the disc and studs and also through nipples (Al) on the bottom of the container (A), to which nipples may be secured the ends of the oiling pipes. Midway between the ports (133) a corresponding number of other ports (Ed) give communication between the upper and underside of the disc (El). Thus the reciprocating pump is rotated successively over the charging and discharging ports and operated so as to draw in and deliver lubricant through the ports.
No. 8,113, of Igoe dated under Convention September 21st, i9e4.—A. Farkas and J. Kieffer, Paris.—This invention relates to a ball joint or coupling which comprises a central spherical part (a) secured to, or forming part of, one of the two shafts to be connected, say (b), through which passes at right angles to the said shaft a key (c), providing at two opposite points of the ball (a) two projecting tenons or lugs. Over the part (a) is placed a spherical cap (d) provided with four similar openings or mortises (e) arranged radially relatively to the centre of the said cap and at go degrees relatively to each other. Two of these slots (e) receive the projecting ends of the key (c), while through the other two pass tappets (f) which are secured, at right angles to the key (c), to two opposite points of a casing (g). This casing or box (g) is carried by, or forms part of, the other shaft (h) or part to be coupled. Its inner surface is spherical and co-operates with the spherical outer surface of the cap (4), in such a manner that the latter constitutes a ball point connecting the two shafts (b and 0/). The width of the slots (c) is equal to the thickness of the key (c) and of the tappets (f), but their length is greater than the width of the said key and tappets, so as to allow free movement of the parts in contact during various oscillating movements to which they are exposed relatively to each other, during the rotation of the shafts when the latter are not in line.
