Title: Improvements in and relating to machines for applying corks or stoppers to containers
Inventor: BROOKS JOHN LUKE
IPC: B67B1/04
Filed: 1954-10-05
Abstract: 821,222. Stoppering or corking containers. FLOWER & CO. (ENGINEERS) Ltd., J. W. Jan. 3, 1956 [Oct. 5, 1954], No. 28704/54. Class 125(2) In a stoppering or corking machine in which the stopper &c. is rotated as it is inserted by a rotating and reciprocating plunger, the plunger is lowered to insert the stopper, then raised part way to allow the stopper to untwist, and then lowered again to complete the insertion. As shown containers are fed by a star 51 from a conveyer 62 to a table 4 which is carried by a lower tube 2 rotatably mounted on a central pillar 1, the containers being justified by a star 61 rotating with the table. Keyed to but slidable along the tube 2 is an upper tube 5 having an upper flange 6 apertured to receive a plurality of stoppering heads 7. Tube 5 and hence tube 2 and heads 7 are rotated by a shaft 41 through a cog 38 and a ring gear 39 secured by bolts 97 to the top of tube 5. The heads each comprise an outer fixed cylinder 8, an inner cylinder 9 slidably mounted therein and a plunger 10 slidable and rotatable in cylinder 9. The plunger has a resilient head 27 for engaging the stopper and a helical groove 25 in which work pins 26 carried by fixed cylinder 8 and passing- through slots in cylinder 9 so that, as cylinder 9 and plunger 10 are lowered, the latter is also rotated. The upper part of cylinder 9 carries rollers 31, 32 running on a cam 35 mounted on pillar 1. The cam is shaped as shown in Fig. 5 with a first depression C to lower the plunger, a flat E to raise it slightly and allow the partiallyinserted stopper to untwist, and a second depression G to lower the plunger to complete the stoppering. A spring 22 acts between cylinder 9 and the plunger to allow the latter to yield to an over-height container. Cylinder 9 carries stopper and container centering bells 42, 43 constructed as described in Specification 748,356. A hood 76 is carried by pillar 1 and surrounds the heads. The hood, cam 35, heads 7 bells 42, 43 and tube 5 can be vertically adjusted on pillar 1 to suit different container heights by rotating a nut 90, meshing with a thread on the pillar, by means of a hand rotated worm 93 meshing with teeth on the outer face of the nut. Stopper feed (Fig. 3).-Stoppers are conveyed one at a time from a shoot 64 and snapped into the bell 42 by a swinging fork 65 which has a tail 68 to block the succeeding stopper. The fork is pivoted at 72 to the end of an arm 74 extending from a bracket 75 fixed to the hood 76 enclosing the stoppering heads. A push rod 84 couples the fork 65 to a lever 78 carried by a shaft 77 mounted in bracket 75. Shaft 77 carries a second arm 79 extending through an aperture 81 in hood 76 and fitted with a roller 80 working on a cam 82 fixed to flange 6 of tube 5 (see also Fig. 1). Adjacent each head 7 is a dip 83 in the cam which allows a spring 85 to swing arm 78 inwards so that push rod 84 causes fork 65 to feed a stopper.

Abstract: 1,056,494. Producing tubular films. SOC. EDISON. July 19, 1963 [July 26, 1962], No. 28765/63. Heading B5B. An apparatus for the production of tubular films by the known " blown tube " process is provided with an annular extrusion die having a cylindrical core 18, Fig. 4 (not shown), whose peripheral surface has a series of circumferential ribs 19, 19<SP>1</SP> projecting into the duct (of annular cross-section) through which the heated film-forming material is forced to the annular extrusion orifice. The extruded tubing is inflated in the usual manner by introducing air into it at somewhat above atmospheric pressure, while at the same time the tubing is stretched longitudinally and flattened by means of a pair of pinch rolls in the usual manner. The hot extruded tubing is cooled in two separate zones, the first being located immediately after the extrusion die where the tubing undergoes longitudinal stretching and the tubing in this zone being cooled from 160 C. down to 110 C. The second zone is located in the region through which the inflated tubular film is drawn before reaching the converging guide members leading to the drawrolls. In both zones the tubing and tubular film is cooled by directing on to its exterior cooling air from a number of uniformly spaced holes in the inner surface of an annular duct coaxial with the tubing and tubular film. The converging guide members 27 and 27<SP>1</SP>, Fig. 8 (not shown), leading to the draw rolls 29, 29<SP>1</SP> comprise metal pipes through which cooling water is circulated. The tubular film 23, after having passed through the nip of the draw rolls 29, 29<SP>1</SP> and being thereby flattened, is passed through a trough of cooling water 31, over a guide roll 30 and two additional guide rolls to winding or drag rollers 36 and 36<SP>1</SP>. Draw rolls 29 and 29<SP>1</SP> are driven through the infinitely variable speed gear 32 and worm gears 33 which also drive the winding rollers 36 and 36<SP>1</SP> through chain 35, a second infinitely variable speed gear 34 and chain 37. The flattened tubular film is woundup on the takeup spools 38 and 381 which are in direct contact with the rolls 36 and 36<SP>1</SP>. Optional features of the apparatus which are described with drawings include as suction system for drawingoff any noxious vapours evaporating from the hot freshlyextruded tubing, a closed circuit oilcooling system for the extruder, a device enabling a filter in the extrusion head to be easily changed, a device for automatically controlling the wall thickness of the flattened tubular film, and a device for embossing the flattened tubular film.
