Abstract
400,426. Glass manufacture. DICHTER, J., 4, M³nzstrasse, Berlin. Nov. 3, 1932, No. 31060. Convention date, May 3. [Class 56.] In a machine for making glass vessels from tubing in which a tube is held rotatably between two supports and heated intermediately thereof, and blown in a mould by the pressure of gas admitted to the tube, means are provided for stopping rotation of the supports during the moulding operation. As shown in Fig. 1, the machine has eight pairs of holding devices which are advanced step by step around a vertical central axis. The machine may be horizontally arranged, and the holding devices may be fixed relative to the machine. Long tubes or measured lengths may be used. A driving shaft 6 is adapted, through bevel gears 9, 9<1>, to rotate a feed disc 7 which, at each revolution, moves discs 10, 4, 4<1> through an eighth part of a revolution about the shaft 3. A disc 8 is arranged to lock these parts between movements. Chucks 12 are carried by disc 4<1>, while chucks 13 are movable on parallel guide bars carried by discs 4, 4<1>. The chucks are rotated through gear wheels 15 .. 19, gear wheel 16 being displaceable on shaft 20, which has a claw coupling 21 for interrupting the rotation through levers 22, 23 operated by a cam. The chucks 13 are moved through rods 24 engaging a cam track 25. Levers 26, 26<1> are adapted to be swung by cam mechanism 29, 30, 30<1> about a shaft 27 to form shoulders in, or otherwise constrict the softened tube either before or after drawing. A mould 32 comprises two jaws operated by bevel gears 36, 36<1> and gear wheel 37 which moves racks 38, 38<1> carrying the jaws in opposite directions. The mould carrier 39 is radially displaceable in a slide 40 by suitable gearing means. The disc 4<1> carries above it a ring 46, Fig. 3, having bearings 47 for parallel guide bars 48<1> on which slides a blast head carrier 50 connected to the air supply by a hose 51<1>, pipe 51, valve plates 58, 60 and supply pipe 59. A pipe 52, rotatable in the carrier, is connected with the glass tube by rubber tubing. The carrier 50 is connected to a cord 54 passing over pulleys 55, 53<1>, the former having a shaft 56 which, during rotation of the disc 4<1>, frictionally engages a lever 57 and prevents the blast head carrier from sliding down. The manufacture of an ampoule is shown diagrammatically in Fig. 6. The tube is heated, (a-b), shoulders formed, (c), drawn, (d), and blown in the mould, (e), if desired after further heating. The breaking point may be formed simultaneously or subsequently, in the form of an enlargement or a constriction, in the latter case blowing air against the depression facilitating breaking. The ampoule is now separated (f) and the tube closed and flattened, or a rounded end formed by blowing in a mould (g). The base mould now sinks to feed the glass tube and working recommences (h). The tube could be closed at its upper end and air blown in from the bottom. The machine is also adapted to effect shapings of larger diameter than the tubing.
