LUBRICATOR.— Plane.— No. 25,734, dated December 11th, 190n.—A series of horizontal cylinders (E) are arranged con
centrically round a shaft (B), but the shaft has an eccentric (E), and each cylinder carries a spring-controlled plunger (F), whose head (F1) bears against the eccentric. With each of these cylinders a conduit (K) communicates, and these conduits are constantly fed with lubricant from a central reservoir common to them all. Within each cylinder is a cylindrical valve (M) controlled by a spring (01. As the eccentric (D) rotates, each plunger is advanced in turn, and carries with it the oil which enters the cylinder by an inlet (H). The plunger closes the orifice (H) as it advances and carries the oil for ward, at the same tirne. forcing back the spring-controlled valve (Mi. The oil is thus discharged through the orifice (N), and as the plunger recedes, the valve advances and covers the outlet. The pin (P) limits the forward movement of the valve (11), and as soon as the port (Ili is again uncovered, a fresh charge of lubricant enters the cylinder (E) ready for the next advance of the plunger.
AXLE. — Hay. —No. 4,517B, dated March 4th, 1905.—At each end of the fixed steering axle (A), a pin (E) is carried and pivoted thereon is a sleeve (E). The exterior of the sleeve is cylindrical, and carries free upon it the road xvheel. The interior of the sleeve is slotted, and receives a wedge-shaped tongue (B) secured fast noon the pin (E). Steering is effected by swinging the sleeve (F) about the pin (13) by an arm (El and the wedge shape of the tongue (11) together with the flared mouth (Li of the sleeve, permits the required turning angle.
R AD IAT OR. —I lam ilton.—No. 6,887, dated April 1st, 1905.—The radiator coinprises a number of pairs of elements (AAIL Each member of the pair is dished and provided with a central neck (13). The members (Al) fit into the members (A) and the necks (B) of adjacent pairs also fit one into the other. Between the elements of each pair a loose disc (C) is interposed, and projections (A2) are formed on the elements to retain th.:1 disc laterally : the disc also has projections (Cl) at its edges to retain it in a central position within the chamber formed by the elements (AA)). It will be seen that a number of these elements built together form for themselves a central conduit by the necks (B), whilst the fluid passing through them is made to traverse round each of the interposed discs (C). MAKE AND BREAK DEVICE.Noble—No. 1,482A, dated January 25th, 1905.—This device is situated in the secondary circuit, one wire being connected to the terminal (E) and the other to the spring contact (L). The arm (H) is of insulating material, and is rocked by a cam (A). A series of these devices may be used side by side and operated by their respective cams for the purpose of distributing the spark to the proper cylinders at the required moment. The spark occurs either when the contact point 0) touches the spring (L), or when it is tircught sufficiently within jumping distance of the same.
LUBRICATOR, STEAM.—Nuttall.-No. 8,495, dated April 20th, I905.—The oil cup (6) has mounted within it a springcontrolled valve (9). The valve is seated upon the outlet orifice (10) of the cup, and is operatively connected with a lever 1171, by which it may be raised against the action of its spring (15). Steam is admitted to the cup by a conduit (24) for the purpose of driving the oil therefrom. The lever (17) is connected by suitable mechanism with some part of the engine, so that the valve (9) is lifted from its seating intermittently so long as the engine is running, but direc ly the engine stops the valve closes and stops the supply of oil to prevent waste.
