Governor, Engine, Sparking Plug, Clutch and Vapouriser.
No. 11,753, dated May 21st, 1904.— Governor for Explosion Engine.—F. Smith.—The governor comprises a suction valve (a) carried by a rod (c) free to slide in a bearing (d) on an arm (f). Springs (o and r) retain the valve in a normal position though allowing movement in both directions. The arm (f) is operated
by hand and slides in a cam slot (h) in the wall of the induction conduit (b), in which the valve is mounted. By moving the arm so that the valve is raised or lowered in the conduit the maximum -opening of the valve is regulated, whilst the automatic operation of the same is unimpaired.
No. z89, dated January 4th, 19o5.— Engine for heavy oils.—Ellis and Mon corn, Ltd., and A. Jude.—This invention is to prevent sooting when heavy oils are used. It is found that when a light oil comes into contact with a hot surface, such as a vapouriser, the oil takes a globu lar form, and does not become split up into its elements ; but a heavy oil does not take this form, and therefore is, to some extent, destroyed, and sooting results. To prevent this it is proposed to mix with the heavy oil a certain proportion of water for the purpose of retaining it in globular form. To this end the heavy oil is fed from a tank (A) to a rotary pump (B), and the water is fed from the top of the water jacket (E) to the same pump. The mixture is then carried to a mixing device (I), where the water and oil are thoroughly amalgamated. Once amalgamated in this manner they are not found to easily
separate, and can be fed from the chamber (I) to a vapouriser (0). Valves (D) and (Cy), controlled by an arm (Dl) operatively connected with the governor of the engine, regulate the flow of both the water and the oil. This mixture is found not to soot.
No. 12,760, dated June 6th, 19o4.— Sparking Plug.—Dossetter.—The object of this invention is to so construct a plug as to avoid the exposure of metal parts likely to cause short circuiting. The usual metal part (a) is screwed into the cylinder and carries one of the sparking
points (f). Secured in the part (a) by a gland nut (c) is a porcelain body (b), in which the corresponding sparking point (e) is mounted. The top of the porcelain body is slotted at (k) to receive the wire (i), and the latter is held in place by a screw-threaded plug (j) of insulating material, which forces the wire down upon the base (h) of the sparking point (e).
NO. 12,193, dated June loth, 19o5.— Positive Drive Friction Clutch..-Franklyn and Isaacson.—The members (z) and (a) have correspondingly coned faces and constitute the usual friction clutch, one member being movable laterally towards the other. On the inner periphery of the member (1), supposing this to be the driving member, teeth (5) are provided. On the boss of the member (2) a lever (icy) is mounted, carrying a spring-controlled
pawl (to). The two members are first
brought into engagement by advancing one towards the other, then, as the speed increases, the pawl (to) is thrown out by centrifugal action so that it lies in the path of, and engages one of the teeth
(5) of, the male member, thus locking the male and female members together. To prevent shock when the pawl comes into engagement a rubber buffer (20) is employed.
No. 24,489, dated November iith, 1904. —Vapouriser.—Albone.—The fuel to be vapourtsed is passed through the conduit ia) and strikes the tubes (d), which obliquely cross the same. The tubes are preferably of copper, carried in a casing (e) and supported by plates (e) (el). The plate (e) bears against a seating in a member (hi which connects the fitting (i; elastically (by means of springs, k) to the casing. A portion of the exhaust is admitted by the fitting (i) to the tub e.s (d).
