Title: Improvements in and relating to carburetting apparatus for internal combustion engines
IPC: F02M25/022
Filed: 1926-08-05
Abstract: 283,240. Grapes, G., Hamilton-. Aug. 5, 1926. Vaporizers, external. -The unvaporized particles of fuel in the mixture passing from the carburettor to the engine are caught in an inclined externally-heated retort which is offset from the mixture conduit and is provided with a number of troughs or the like over which the unvaporized liquid flows the heating being such that the temperature increases towards the lower end of the retort, to which a controlled supply of air is preferably admitted. The mixture from the carburettor passes through a sinuous conduit A, Fig. 6, the unvaporized particles being thrown out by centrifugal action into a semi-spherical trap chamber 8 communicating through an aperture 8<a> with a retort 10, Fig. 2, provided along its length with a series of transverse troughs 9 and at its lower end with a circular shallow trough 12. The retort is enclosed in a casing 14 to which gases from the exhaust manifold are admitted at 14<a>, the casing being provided at the lower end with an expansion chamber 15 and with a baffle 16 adapted to deflect the exhaust gases on to the trough 12. The chamber 15 may be surrounded by a casing 15<a> containing air, charcoal, pumice or other non- heat conducting material. The walls of the upper troughs are lined with strips of gauze, the capillary action of which assists in feeding the fuel to the lower troughs, and one or more tubes 19 of gauze are situated in the. mouth of the- 'retort.. Air from a filter 21 may be admitted through a conduit 20, a thermostatically-controlled valve 22, and a duct 23 to a pipe 24 extending to the bottom of the retort. Alcohol or other fuel or water or a mixture thereof may be supplied to the duct 23 from a tank 40 through a valve-controlled pipe 39. The vaporized fuel from the retort passes through the chamber 8 and mixes with the main stream of mixture passing through the conduit A, the portion 42, Fig. 6, of which is of enlarged crosssection, to reduce the rate of mixture flow. The portion 42 is attached to a conduit 44 leading to the engine, a conical-lipped extension of the conduit 44 projecting into the mouth of the portion 42, and the lip 45 serving to deflect downwards any liquid particles deposited on the outer wall of the extension 43. Air from the filter 21 may be supplied to the mixture through a suctionactuated valve 48 and a conduit 47 the outlet of which passes through the flange 46 of the conduit 44. To prevent flooding of the retort at starting, a catchment chamber may be provided which communicates through a slot with the conduit A on the carburettor side of the inlet to the chamber 8. During normal running, the particles of fuel are carried over the slot by momentum, but at starting and during slow-running the particles of heavy unvaporized fuel pass into the catchment chamber, which is provided with a controlled outlet communicating with the retort, and with an overflow leading to a reserve fuelsupply tank. Specification 143,213 is referred to.

Title: Improvements in and relating to brakes
IPC: F16D51/46
Filed: 1924-08-18
Abstract: 243,053. Rubury, J. M. Aug. 18, 1924. Blocks and shoes acting on drums; actuated or applied by running axle or wheel.-Brakes of the kind in which shoes are pivotally connected together and are capable of limited movement about the axis of the drum with which they engage comprise a leading shoe adapted to be operated at one end by a cam and pivotally connected at or near the other end to a fixed support and a following shoe pivotally connected at one end to the leading shoe at a point other than the fixed pivot and adapted to coact at the other end with an abutment whereby the leading shoe, when applied to the drum, transmits force to the following shoe. The abutment may be fixed or may form part of a double cam which actuates both shoes, or it may be so arranged that the reaction of the following shoe thereon tends to turn the cam in such a manner as to increase the pressure on the leading shoe. Fig. 1 shows a leading shoe b mounted on a fixed pivot e and a following shoe c pivoted to the shoe b at h and adapted to engage a fixed abutment z. When the cam i is operated both shoes are applied and the pressure on the shoe c is augmented by the frictional force acting on the shoe b. Fig. 8 shows a form in which the shoes b, c are both connected to fixed pivots e by links e<1>, e<2> and are connected together by a link h<3> which is adjustable in length to compensats for wear. The cam i acts upon both sides and serves as an abutment for one or the other according to the direction of rotation of the drum. The links e<2>, h<3> may be dispensed with, the shoe c being in this case directly pivoted to the shoe b. The face i<1> of the cam which engages the shoe c is disposed further from the axis of the cam than is the other face, so as to compensate for the extra movement imparted to the shoe c by the shoe b. Fig. 6 shows another modification in which the cam i is in the form of an eccentric having a flat surface i<2> for engagement with the shoe b, the cylindrical surface of the cam being embraced by a jaw c<2> on the end of the shoe c. The centre of the eccentric may be shown as arranged to fall below the centre of the shaft d, whereby the frictional force on the shoe c tends to increase the turning movement given to the cam by the lever f in applying the brakes. A similar effect may be produced by connecting the end of the shoe c to an arm on the spindle of the cam. One or more intermediate shoes may be introduced between the two end shoes. Fig. 10 shows one such arrangement in which the shoes b, k are mounted on fixed pivots e and are connected to each other and the shoe c by links h', h<5>. The cam i has a flat surface i<2> for engaging the shoe b and the cylindrical surface i coaxial with the cam spindle engaged by a jaw part c' on the end of the shoe c.
