Title: Improvements in or relating to machines for producing glass vessels from tubing
IPC: C03B23/07
Filed: 1932-11-03
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.

Filed: 1923-12-12
Abstract: 230,544. Raphael, F. C., and Glover & Co., Ltd., W. T. Dec. 12, 1923. Earth-continuity couplings.-In a junction box comprising a back plate and a flanged cover having recesses for the entry of conductors and a flat bonding ring between back plate and cover the bonding ring is slit at places coincident with the recesses to form one or more circumferentially extending tongues extending across each recess. The tongues are preferably of springy metal and so shaped as to apply a constant pressure upon the cable. The ring is riveted to the back plate. A back plate a has projections a<2> threaded to receive screws passing through holes in upstanding projections b<2> in the cover b. The intermediate portions of the flanged cover form recesses for the entry of cables and a bonding ring c cut away at c' to clear the projections a<2> is slit to form one or two circumferential tongues c<1>, c<2> in register with the cable entries. One of these tongues c<2> is pressed upon an entering cable by the cover and where two are used the other c<1> exerts a constant pressure under the cable to maintain an efficient bond under conditions produced by wear, vibration &c. In a three-way box the back plate and cover are cut away along a chord and the back plate may be upwardly flanged along this edge to meet an outwardly turned flange on the corresponding portion of the cover.

In a motor vehicle tailgate fastening a latch 6 is permitted to operate by a release member 15 the movement of which-member 15 is obstructed when a window 1 is not lowered to a position safe for opening the tailgate 2 but when latch 6 is in the release position the member 15 is moved to a position in the path of the window 1, shown dotted in Fig. 4, to obstruct the raising of the window 1 until the latch 6 is again fastened. The member 15 is of cranked form and is connected at 14 to a pawl 9, pivoted at 12 and when the window 1 is up the end of the pawl 9 lies in the path of a pawl 10, connected to the latch 6, to prevent rotation of the latch 6 to the release position with a pin 7. When the window 1 is lowered the member 15 pivots the pawl 9 to permit a spring 8 to facilitate rotation of the latch 6 to the release position and to move the end of the pawl 10 into a blocking position behind pawl 9 so that the member 15 cannot be moved and hence the window 1 raised until the tailgate 1 is shut and the latch 6 rotated to the fastening position by pin 7.

The connector 26 consists of a flat metal plate 27 having reinforcing bars 28 welded on both edges and is passed through the slot 21 in the column so that its projecting ends are received in slots 24 in the beams. The slots 21, 24 and remaining spaces between the column and beams are filled with concrete grout. In modifications, Figs. 4 and 5 (not shown) a connector comprises a metal tube having diametrically opposite flat metal webs welded on the tube and reinforcing bars welded to the outer edges of the webs and is used where beams are subject to torsional forces. When a beam is to be joined to a column a vertical bar is welded to the end of the connector and cast or grouted in the column, Fig. 7 (not shown). Two beams at right angles are connected to a column, Fig. 8 (not shown) by casting two connectors in the column, each welded to the other at right angles, one of which has a vertical bar welded to it as in the case of a single beam connection. Figs. 9 and 10 (not shown) illustrate a connection of four beams at right angles to each other to a column having one connector deeper than the other with an aperture in it through which the smaller connector passes.
