Abstract: 117,525. Hayes, W. H. Aug. 28, 1917. Vaporizers, external. -In a vaporizer for an engine using paraffin oil, &c., a triangular mixing - chamber A, Fig. 1, is traversed by a heating - pipe H, through which part of the exhaust gases passes. Air is drawn in through a pipe M having a bell-shaped mouth M', into which exhaust gases are discharged by a nozzle L arranged adjacent a baffle L'. The entry of the mixture of air and exhaust gases into the chamber A is controlled by valves Q, 0 secured to a spindle O<1> having a flat or groove O<11> arranged to control the delivery of paraffin from a chamber U connected to a pipe U<1> provided with a wick V. The spindle 0' is controlled by a spring S and is operated by a lever R. The vaporizer is held in place by turn-buttons F engaging lugs E, the junctions C, H<1> with the induction-pipe D and the exhaust-pipe G being formed by spherical jointing - surfaces. In a modification, the passage of exhaust gases into the pipe H is controlled by a cock 1, Fig. 3, and a branch pipe 3 leads exhaust gases into a valve casing 5. Air is supplied through passages 17 arranged to open after the inlet from the pipe 3. The entry of exhaust gases and air into the casing 5 is controlled by a valve 6 rigidly connected to a valve 7 controlling the inlet to the chamber A. The valve 7 is arranged to open before the valve 6. Paraffin &c. is supplied through a cock 14. According to Provisional Specification 12337/17, petrol may be used instead of paraffin for starting the engine, the passage of hot exhaust gases into the combustible mixture being meanwhile prevented by closing a valve, thus preventing pre-ignition.

IPC: B61K3/00
Filed: 1928-05-01
Abstract: 310,194. Teale, J. W. May 1, 1928. Lubricant conveyed by mechanical means.-A fixed device for lubricating axles of corves and similar trucks is provided with a wheel 1, toothed or recessed to retain the lubricant, and mounted eccentrically by having a central hole larger than the spindle 2 on which it is mounted. The greater portion of the wheel is submerged in the lubricant contained in a reservoir 4 supported by brackets 6 between the rails (not shown). When the axle of the corve passes out of contact with the greasing wheel, the inertia of the lower part of the wheel minimizes its rotation, and so avoids wastage of lubricant.

Abstract: 257,014. Reyrolle & Co., Ltd., A., and Leeson, B. H. May 20, 1925. Sparking - preventing and are-rupturing devices; electromagnetic switches. -Electric contactors as circuit-breakers have adjacent to the contacts a conduit or chimney through which the arc vapours are blown by a jet of air which is produced by operation of the switch. As shown in Fig. 1 the switch comprises fixed contacts D<1> adapted to be bridged by a conducting bar D which is attached by a rod B<2> to the core B<1> of the operating electromagnet B. The core B<1> also carries a piston F working in a cylinder E and on release of the electromagnet core the piston is moved down by a spring G forcing a stream of air through holes E near the base of the cylinder and between the separating contacts. The arc gases are thereby blown upwards through conduits H of refractory insulating-material which have open ends adjacent to the contacts. The switch is contained within a metal casing A provided with air vents A<1>, A<2>, the conduits H being arranged to prevent the arcs spreading to the metal container. Alternatively the core itself may act as a piston. In the electromagnetic contactor shown in Figs. 4 and 5 the piston B<6> is attached to the core B‹ and works in a cylinder communicating with pipes E<5> provided with outlet slits E immediately behind the pairs of co-operating contacts D<3>, D<6>. The spring mounted movable contacts D<3> are operated when the core B<5> is released through a rod B' and rotary contact spindle J', and as the contact separate jets of air are forced between them from the slits E<6> so that the rising arc gases are forced upwardly through the conduits or chimneys H'. Each contact carries a suitable arcing barrier D<8>.
