Title: Apparatus for and method of forming glassware
IPC: C03B9/193
Filed: 1942-09-11
Abstract: 560,672. Making hollow glassware. BRITISH HARTFORD-FAIRMONT SYNDICATE, Ltd. Sept. 11, 1942, No. 12868. Convention date, Sept. 13, 1941. [Class 56] Relates to the method of and apparatus for forming hollow glassware, as described in Specification 532,778, in which a charge of molten glass falling into an inverted parison mould is stopped at a predetermined level and supported by the tapered upper part of a plunger moving upward, so that the charge is raised and pressed in the mould. The present invention consists of mechanism for guiding, operating, positioning, and cooling the plunger. The plunger 19, Fig. 1, is reciprocated vertically by a pneumatic cylinder 7 and moves between the position shown and its highest point, at which the tip occupies the position 76. The plunger co-operates with a divided ring mould 45, a parison mould 47, and a bottom plate or baffle 50 which may be operated as described in' Specification 257,637, [Class 56]. At the commencement of a parison-forming. cycle, the moulds are closed, and the plunger is raised by a spring 38 until its tip occupies the position 75. A charge of glass enters the mould and its downward movement is checked by the tip of the plunger, as shown in Fig. 9, while the open end of the mould is closed by the baffle 50. The plunger now moves upwards and presses the charge of glass to form a parison with the neck portion of the finished article. Next, the mould 47 is opened slightly or " cracked " to allow the parison to reheat, the baffle 50 is removed, and the parison is expanded slightly and prevented from expanding by puff blowing while it is standing free from the mould. Finally, the parison is transferred to a finishing mould by means of the ring mould, the plunger being moved to its lowest position to allow the ring mould to be moved. The parison is blown to the finished shape by the method and means described in Specification 532,778. The parison mould 47 is kept closed by grippers operated by a heavy spring 58, and is opened by crank arms which rotate levers 67 that force the ends of the grippers apart. The plunger 19 is cooled by liquid which passes into its interior through passages 104 in the piston rod 25 of the pneumatic cylinder 7 and escapes into a drain pipe 105. The liquid is admitted to the passage 104 from a supply pipe 113 by a valve 118 which is operated by the same supply of air pressure that raises the plunger 19. A regulated quota of cooling- liquid is thus supplied to the-interior of the plunger at each pressing stroke of the plunger. An indicator may be provided to show the position of the plunger at the end of the pressing-stroke. This consists of a movable rod 97, Fig. 9, which extends through a vertical opening 98. The rod 97 is moved by the piston 26' of the cylinder 7 and indicates the position reached by the plunger 19 at the end of the pressing stroke.

Title: Improvements in and relating to auxiliary carburation devices for supercharged internal combustion engines
IPC: F02D19/12
Filed: 1939-04-29
Abstract: 528,207. Charge forming devices. SOC. ANON. SOLEX. April 29, 1939, No. 12903. Convention date, June 8, 1938. [Class 7 (iii)] In an auxiliary carburation device, for compressor supercharged engines, having means for supplying to the inlet of the compressor when the engine has to furnish extra power, an anti-detonating or other supplementary fuel, the fuel is delivered solely under the action of the pressure downstream of the compressor and the delivery varies directly as that pressure. A small reservoir 8 supplied with fuel from a tank 19 to a level determined by a float 23, communicates, above the fuel level with the delivery conduit 13 of a compressor 1 and the pressure thus applied to the free surface of the fuel in the reservoir 8 drives the fuel up a dipping tube 9 into the air inlet of the compressor at 11. Valves 14, 16 in the tube 9 and the conduit 12 connecting the reservoir 8 with the pressure conduit 13 control the delivery of the fuel and may be operated simultaneously with the control lever 5 of the air inlet valve 3 of the compressor, or independently thereof by a barometric capsule exposed to the pressure conduit 13. The fuel may be discharged directly into the compressor at 11 or, it may be delivered into a passage or chamber communicating with the air inlet of the compressor upstream of the air valve 3 through a restricted orifice so small as to prevent the suction in the compressor inlet from affecting appreciably the atmospheric pressure prevailing in the chamber. A mixture of fuel and air may be delivered to the inlet 11 by exposing the fuel pipe 9 above its calibrated orifice 10 to the pressure conduit 12 through a restricted orifice not shown.
