Title: Method and device for securing yarn packages
IPC: D01H9/16
Filed: 1964-08-27
Abstract: The invention relates to a method whereby a bobbin 4, Fig. 1, can be wound on a drawtwisting machine so as to form both a transfer tail thread 17 and an initial thread end 16 and whereby when the bobbin 4 is removed from the twisting spindle at least one of the two thread ends is automatically attached to a fixation device 7 on the bobbin. The twisting ring 2 is first placed opposite an auxiliary spool 8 below the bobbin 15, the spool 8 taking up waste yarn 14 the ring 2 is then raised in stages to (a) permit the yarn to be caught by a first notch 12 (not shown) in a collar 10 of the spool 8 (b) wind a transfer tail 17 on the bottom of the bobbin 4 (c) cause the package 15 to be wound. Thereafter the ring 2 is lowered to cause (d) the initial thread end 16 to be wound at the bottom of the bobbin 4 (e) the yarn to be caught by a second notch 11 in the collar 10 and (d) more turns to be wound on the auxiliary spool 8. When the fully wound bobbin is pulled upwardly off the bobbin spindle, Fig. 2, the notches 11, 12 cause the lowermost turns of the windings 16, 17 to be pulled downwardly relatively to the bobbin, and these yarn ends are then wedged between a fixation device 7 and the bobbin to hold them fixed to the bobbin. The yarn ends are then severed at 21, 22 between the notches 11, 12 and the fixation device 7. The fixation device 7, Fig. 6 (not shown) may be in the form of a spring-like clip, one arm 25 of which is extended upwardly between inner and outer tubes 5, 6 of the bobbin 4 and the other arm 24 of which lies on the outer surface of the outer tube 6. Various embodiments of the device 7 are disclosed. There may be two fixation means, one for the transfer tail and one for the intial thread end.

Filed: 1965-05-14
Abstract: A radiant/convector gas fire capable of burning town gas or gas of a higher calorific value comprises an outer casing 10, a hot gas chamber 14 leading to flue ducts 15, an air heater 18 disposed rearwardly of three radiants 12 which are supported by a main frame 11 above and spaced from a burner assembly 13, mixing tubes 25 of which lie at right angles or obliquely to the plane of the radiants. The burner assembly comprises a separate aerated burner 24 for each radiant, each burner having a mixing tube 25 comprising a flared inlet 34 holding a gas injector 26 connected to a supply conduit 27 which is internally partitioned to give two chambers 29, 30, one of which is connected to the two end mixing tubes while the other is connected to the central mixing tube. Air to inlets 34 of each mixing tube is manually regulated by moving a plate 46 with slots 47 over a fixed apertured plate 45, Fig. 5 (not shown), the air and gas mixture passing through a Venturi 35 to a straight slightly upwardly inclined pipe 36 diverging from the Venturi throat and connected to an upwardly curved forward end 37 terminating in a flared outlet 38 of the same shape as the bottom opening 41 of the radiant it serves, the outlet 38 being covered by a perforate ceramic or metallic closure plate 39 below a combustion chamber 40. Convection air passes through a grill 21, through spaces between pipes 36 extending across a passage 20, upwardly rearwardly of the radiants, around flues 15 and thence through an outlet grille 23. In another embodiment, the partitioned gas conduit 27 may be replaced by separate conduits, or there may be one conduit supplying the two outer mixing tube injectors and another supplying the central mixing tube injector.
