Filed: 1920-01-31
Abstract: 155,138. Godward Carburettor Co.,. (Godward, E. R.). Jan. 31, 1920. Spray carburettors.-Relates to means such as .described in Specification 132,873 for vaporizing the mixture, and consists in employing in the mixing-chamber a system of piled disks or plates having a central inlet passage extending upwardly through the pile, the mixture passing between the plates to peripheral outlet passages. Air passing the butterfly valve 5, Fig. 1. divides into two streams. The primary air stream passes by way of openings 30 over the radially slotted fuel-jet 25, the mixture passing through controlled triangular ports 29 to a central passage 48 formed by piled and spaced annular plates 46 which serve to further vapourize the mixture as it is drawn by engine suction between the plates to the outlet 13. The supplementary air stream passes through controlled triangular ports 21 to the annular space 54 between the plates and the surrounding casing so as to combine with the mixture issuing through the passages 51 between the peripheries of the plates. Warm air is admitted by a pipe 15 to a jacket 14 surrounding the vapourizing chamber and is exhausted through a pipe 16 by the suction effect of the air passing in the passage 3. A throttle valve in the form of three concentric sleeves 41, 35, 38, which respectively and simultaneously control the supplementary air ports 21, the mixture ports 29 and the fuel jet 25, is operated by a radial rod (not shown) attached to the portion 32 of the throttle and passing out through a slot in the wall of the carburettor casing. By turning the throttle valve beyond its extreme position the mixture may be entirely shut off, the auxiliary air alone passing to the engine cylinders for cooling and braking purposes. The piled plates are spaced apart by providing radial lines of nodules 52, 53 above and below alternate plates, as shown in Fig. 5. The plates may be dished, as shown in Fig. 6.

Abstract: 347,754. Fluid-pressure brakes. TOMLINSON, A. V., 65, Victoria Street, London.-(Westinghouse Air Brake Co. ; Wilmerding, Pennsylvania, U.S.A.) Feb. 3, 1930, No. 3647. [Class 103 (i).] A vehicle brake system comprises a valvecontrolled fluid-pressure cylinder and a hydraulic transmission system operated thereby for transmitting the pressure to the brakes, the two cylinders being arranged side by side in a common casing. Fig. 2 is a plan view of the apparatus. The vacuum cylinder 7 forms part of a casing 5 which includes a web 24 defining a reservoir 23 enclosing the hydraulic cylinder 22 connected to the brake cylinders. The piston 8 is connected by a chain 14 to a lever 12 having an eye 19 which has clearance on a shaft 17 mounted in bearings 16 in the casing. The lever 12 has a pivotal connection 21 with an arm 20 secured to the shaft 17 to which also is keyed an arm 33 engaging through rod 31 the hydraulic piston. A rod 11 operating, through a rocker arm 10, the valve 9 of the vacuum cylinder is connected to the eye 19 of the lever 12. The control rod 13 from the pedal also is connected to the lever 12. To apply the brakes the rod 13 is pulled by the pedal causing the lever 12 to swing and operate the valve 9 through the rod 11. The piston 8 then pulls on the lever 12 and actuates the arm 20 through the pin 21 and thereby the shaft 17 and hydraulic piston 28, thus applying the brakes. The swinging of the lever 12 will not return the valve as long as a predetermined effort is applied to the rod 13. The piston 28 is made of rubber composition and is engaged by the follower 29 provided with passages 37 so that if in the release of the brakes the piston is returned by the spring 34 more rapidly than corresponds to the return of the liquid to the cylinder 22 the piston turns in at the lip and liquid flows from the reservoir 23 through the passages 37 past the piston into the cylinder. Excess of liquid introduced in this way flows back to the reservoir through a port 35 when the piston reaches the normal position.

Abstract: 398,211. Shookabsorbers. RHODES, J. and RHODES, K. A., 66, Ruby Place, Lidget Green, Bradford, Yorkshire. Feb. 8, 1932, No. 3650. [Class 108 (iii).] In shock-absorbers for damping the rebound of vehicle suspension springs hydraulic vane elements operate under valve control apparatus so that the resistance offered thereby varies according to the amount of rebound corresponding to an initial upward deflection of the vehicle wheels and so that the wheels are freely permitted to descend into openings or depressions in the road without interfering with ascension therefrom. Each shock - -absorber comprises a casing q having a cylindrical extension c containing a sliding piston a connected by a link h to a pin m fixed on the vehicle frame or to an arm c12, Fig. 7, pivoted to the frame and about which the casing q is rotated through an arm c<2> and adjustable link f, f<1> by the spring b. When the vehicle wheels descend, a cam h<5> on the link h engages a spring-pressed ball-valve 3 in the piston to permit free flow of liquid therethrough. Normally when relative movement occurs between the vehicle frame and springs the piston a is moved towards the pin m, liquid flowing past the valve 3, while on the rebound the valve 3 closes and liquid is forced through a small duct s, the position of which can be adjusted, the rate of flow being controlled by a ballvalve s<1>, Fig. 9, the position of which is governed by an adjustable spring stop 21 or by a screw 24, 24b. In the latter case, a spring-pressed safety release valve 21a is provided. In the modification, shown in Fig. 7, the shock-absorber casing is pivoted at c<14> to an arm c<2> and is adjustable relative thereto by screws 25a, 25b.
