VAPOURISE R. — Isaacson.—No. 19,806, dated 5th September, 1906.—Ar
ranged within a casing (2) is a conduit (3) in the form of an S, and it is connected at 7 to the combustion chamber. At the inlet end of the conduit (3) is a fuel no221e
(23) having a plunger (24) to remove any corrosion that may collect in the conduit (3). Exhaust gases enter the casing at 14 and so assist the oil to vaporise.
MAGNETO—Williams.—No. 25,632, dated 13th November, 1906.—The magneto generator consists of field magnets (T1) having pole pieces (N, 5) representing the north and south poles, respectively. A core (D) is rotatably mounted between the pole pieces (N, S), and this carries
four wings (d, d, dt, dl). The armature winding (E) consists of an insulated spool (e) with wire coils (el) wound thereon, and it is held and secured to the base (c) by a bracket (Cl). The magnetic lines of force flowing from the north pole piece enter, for example, the wing (d), and flow along the core, through the windings (E), and out of one of the wings (dl) to the south pole piece, thereby inducing a current to flow in one direction through the wire (El) of the coils. It will thus be seen that, as the core continues to rotate, an alter• nating current will be obtained.
TIRES.—Dowron.—No. 20,314, dated 12th September, 1906)—The tire consists of leather rings (G) placed side by side on the rim of the wheel, and held in position by rings (F, Fl, D, DI), which are secured by bolts (H, I). The leather rings, before being used, are subjected to pressure in order to squeeze any mois ture out of t ern, W hen the tires wear down, the rie gs (F, F ) may be removed, and the life of the tire so lengthened.
MOTOR•ONINT BUS S EATS.—Tyler.No. 25,722, dated 14th November, 1906-Covers (t) are pivoted at c to the usual back-rest; so that they may swing forward, and rest on the seat. Abutments (!) are provided on the sides of the covers for limiting their motion to a determined angle, equivalent to the angle made by the back (g) with respect to the seat (e). A coiled spring (h) is secured on the rod (c) in order to raise the covers to their normal position.
VULCANISER.—Ormandy and Others —No. 22,105, dated 6th October, 1906.— A steam-tight casing (A), having tubes (B) from a burner (C) passing through it, is intended to fulfil the function of a
steam-generator. The front wall (Al) of the casing is curved, and the side walls are extended and joined by a plate (Al), shaped, roughly, to suit the contour of the tire, and provided with an opening (Al). The space between the walls (Al, A2) is filled with shot. Movable bars (D) are inserted ; these can be forced inwards by screws (E), and thus cause the surface of the body of the shot to conform closely to the contour of the tire (F)
FEED-WATER HEATER.—Rutherford.---No. 29,680, dated 31st December, 19011—The feed-water heater consists of a casing (50) having partitions (52) projecting across it, laterally, so as to preRent a zig-zag path in which the feedwater pipe (56) is arranged. The exhaust steam enters by the conduit (54), and passes through the zig•zag path in the chamber (50), thus imparting heat to the feed water.
