Patent GB-939259-A (GB)
Title: Knotter mechanism for bundle tying machines
Inventor: WALTERS JOHN GRAY
IPC: B65B13/26
Filed: 1960-01-29
Abstract: 939,259. Knot tying devices. SHERIDAN SERVICE CO. Ltd. Jan. 19, 1961 [Jan. 29, 1960], No. 3336/60. Class 74 (2). In a knotter mechanism which includes a bill rotatable about a first axis the bill comprises a pair of jaws one of which is tiltable about an axis normal to the first axis and carries a cam follower adapted to engage a cam during rotation of the bill, and the mechanism further includes a slidable plunger which co-operates with the follower when the jaws are closed to releasably lock the jaws in the closed position. The bill is mounted in the retractable carriage 1 of a bundle tying machine and comprises jaws 4, 5, the lower jaw 5 carrying a roller follower 15 which moves between cam walls 18, 19 as the bill rotates. Part of the wall 19 is provided by a notched face 28 of a plunger 25 slidable in a bore in the carriage and biased by a spring 32 in the direction of the bill. A notch in the plunger is engaged by a transversely disposed spring-urged latch 38 to prevent movement away from the bill, the plunger being released when the carriage is retracted by the engagement of an adjustable roller 46 with the cam face 45 of a pivoted release lever to depress the latch. Operation.-After the twine has been passed around the bundle and the ends placed adjacent the bill the latter rotates to form the loop (see Fig. 6) the jaws opening after about 270 degrees of rotation, as the roller 15 passes the nose 20 on the inner cam wall 18, to sieze the parts 72, 73 of the twine. As the bill completes its revolution the cam follower 15 engages the head of the plunger 25 and snaps into the notch at 28. The carriage 1 then retracts and the fingers 50, 51 previously held away by abutments 59, 60 on the carriage, move in to strip the knot off the bill. The ends 72, 73 are held in the jaws 4, 5, to tighten the knot until the carriage has retracted sufficiently for roller 46 to engage the lever 45 to unlatch the plunger 25, when the follower 15 rises by overcoming the force of spring 32 and thus deflecting the plunger. In a modification the end of the latch 38 is inclined so that the roller 46 may act directly upon it to unlatch the plunger. In a further modification the plunger may be disposed transversely of the carriage. Specification 820,866 is referred to.

Title: Improvements in or relating to the manufacture of hollow articles from thermo-plastic material
IPC: B29C49/46
Filed: 1941-03-17
Abstract: 568,090. Moulding hollow articles from thermoplastic material. DIXON PLASTICS, Ltd., and TONSLEY, F. H. March 17, 1941, No. 3667. [Class 87 (ii)] A preformed tube 25 is placed in a two-part mould 10, one end of the tube being clamped between a bung 11 and the mould halves, and the other end being flattened, around a conduit 12, in a rectangular orifice formed in the ends of the mould halves. Preferably the tube is softened before it is put into the mould. The mould is then heated (or it may be heated before the tube is inserted) as by plunging it into a bath of hot liquid or by means of jackets around the mould. Then heated liquid is passed through the tube from a cock 16, non-return valve 15 and conduit 13 in the bung ; the liquid leaves the tube through conduit 12 and cock 21. When the temperature-indicator 23 shows that the temperature of the issuing liquid is the same as that in the thermostatically-controlled tank which feeds the cock 16, the flow is stopped by closing cock 21. The cock 16 is then closed, and a cock 17 (which is connected with cock 16) is opened, whereupon compressed air passes through valve 18 and conduit 14 in the bung and subjects the liquid in the tube to pressure, thus expanding the tube into contact with the mould. Then the mould is cooled, as by immersion in a cold bath or by mould jackets, cock 21 is (a) opened so that the compressed air blows the liquid from the tube, (b) closed to build up air pressure in the tube, (c) opened, and the moulded article is removed. The cooling of the mould may take place after the air pressure has been built up in the tube. The moulded article may be a hosiery display form. The thermoplastic material may be cellulose acetate, the heating liquid being water, or celluloid, the heating liquid being oil. Specification 569,093 is referred to.
