Title: Improvements in or relating to the method of and machine for use in cutting or dividing and bottoming tubular glass blanks
IPC: C03B23/11
Filed: 1926-03-15
Abstract: 271,972. Kephart, A. T. March 15, 1926. Forming articles from tubular blanks. - Relates to a machine for dividing a glass tube into two shorter tubes with closed ends. According to the inven. tion, the tubes, which. may have had then ends formed into finished necks in another machine, are carried one at a time from a magazine in a direction at right angles to their length to a position where they are rotated while they are heated at the part where division is to take place. When sufficiently heated, the ends of a tube are drawn apart to effect division, and are then moved backwards to flatten the bottoms by forcing the heated ends against flat plates. The machine is shown in plan in Fig. 2 and in sectional elevation in Fig. 3. The tubes 1, Fig 2, are stored in a magazine consisting of inclined plates 3, 4, and they are released one at a time by gates 9, 10 which are withdrawn alternately and allow a tube to roll on to a carrier 33, Figs. 2 and 3. The carriers are attached to endless parallel chains 15 - - 18 which pass around sprocket wheels 23, 24, and the movement of the carriers conveys a tube to a position where it is supported by four pairs of rollers 35, 36 which are mounted on an upright 163 disposed between the chains. In this position, two discs 52. 53, each having a bevelled periphery, are lowered into contact with the tube and rotate it while its middle portion is heated by the flames of blowpipes 152, 153 which are constructed and supplied with gas and air as described in Specification 248,460. The discs 52, 53 are inclined to the axis of the tube, so that the ends of the tube are forced apart when the glass is sufficiently softed by the gas flames. The ends of the small tubes thus formed are brought into contact with two abutments 103, 104, and a pair of plates 107, 108 are moved upwards into the space between the hot inner ends of the two smaller tubes. The abutments 103, 104 are now moved inwards and force the hot ends of the tubes into contact with the plates 107, 108 thus forming flat bottoms on the tubes. The discs 52, 53 are lifted, and the carriers move and discharge the finished tubes from the machine.

Abstract: 1,027,271. Liquid dispensing apparatus. C. DUCKWORTH AND K. HAMILTON. Feb. 27, 1963 [Feb. 27, 1962], No. 7523/62. Heading A47. [Also in Groups F2 and G4] In a dispensing nozzle having a valve and control means therefor e.g. for use with a coin freed petrol pump &c. (see division G4) sidewardly projecting trip elements are displaced by insertion of the nozzle into an orifice to permit opening of the valve. Bleed ports 13 of pneumatic control means are obturated by four pivotally mounted trip elements 10, covered by a rubber boot 39, upon insertion of nozzle section 6 into a petrol filler pipe, permitting a pressure build up from compressed air supply pipe 18 within cylinder 17 to move piston 15 against a spring 9 to open valve 7. The petrol pump motor switch is simultaneously operated by the pressure within pipe 18 acting, via a piston and link (Fig 3, not shown), and delivery to the nozzle of a volume of petrol, predetermined by the coin freed mechanism, is obtained upon depression of handle 4 to open valve 19. A safety device to prevent spillage comprises valve member 29, connected to vacuum operated diaphragm 30, to permit bleed-off from pipe 18 via passage 38. In normal use the build up of a vacuum within chamber 32 is prevented by air drawn through and into passage 33 from port 36, via pipe 35 and passages 34, by petrol flowing through the nozzle. As the port 36 is sealed by a rising level of petrol and resultant vacuum within chamber 32 unseats valve member 29, so that valve 7 is closed and the pump motor is switched off. The trip elements 10 may also operate trip switches of an electrical fluid valve control circuit.
