Title: Improvements in automatic weft replenishing mechanism for looms for weaving
IPC: D03D45/34
Filed: 1926-09-15
Abstract: 267,015. Hollingworth, E., (Crompton & Knowles Loom Works). Sept. 15, 1926. Shuttles, changing bobbins in, automatically.- Relates to mechanism for replenishing any one of a series of shuttles carrying different kinds or colours of weft and is particularly applicable to pick-and-pick looms for weaving silk. A magazine M, Figs. 1 and 2, having compartments for weft carriers of different kinds or colours is .moved to present a discharge opening 31 opposite a selected one of a series of vertically-moving shuttle boxes 21, is maintained in position opposite the shuttle box, and is moved therewith as the selected shuttle box is moved to running position, The weft detector at the left-hand side of the loom is positioned by pattern mechanism opposite the shuttle-box which is about to become active, while at the same time, the transferrer 32 and magazine M are moved vertically by other pattern mechanism to positions opposite the corresponding shuttle-box on the replenishing side of the loom. The shuttleboxes are then moved vertically by the changebox motion, the transferrer 32 and magazine also moving vertically therewith. If substantial exhaustion of the weft is indicated, replenishment takes place while the shuttle box is moving to running position. The magazine M, Fig. 2, is mounted on a guide 40 moving vertically in a stand 43 and is provided with a rack 44 engaged by a pinion 45 on a pattern-controlled rod 47. The transferrer 32 is movable horizontally in a guide 53 on a part 54 slidable in the stand 43 and is moved vertically by a rod 60, Fig. 1, carrying a pinion meshing with a rack 56 on the part 54. The pinions on the rods 47, 60 also mesh with an intermediate rack 116, so that, while the rack 116 is stationary, the rods 47, 60 move equal distances in opposite directions to bring the transferrer and the selected magazine compartment opposite a selected shuttle box. A further rack 107 operated with a rod controlling the shuttle boxes is geared to the rack 116 by an idle pinion 105 so that, while the rods 47, 60 are locked in position, vertical movement imparted to the rack 107, and hence to the shuttle-boxes, is also imparted in the same direction to the transferrer and magazine. The transferrer 32 is maintained in operative relation with its actuating mechanism by a pin 63 movable in a slot 65 in an actuating head connected to a plunger 66 in a bearing 67. A rod 70 operated by a cam to give a quick movement at each beat of the lay normally moves ineffectively in a hole 69 in the plunger. When weft-replenishment is called for, a spring-controlled pin 84 is raised by engagement of an adjustable head 90 controlled by the weft detector mechanism. A shoulder 99 on 'the rod then engages below the head 85 of the pin 84 and moves it together with the plunger to operate the transferrer 32, the head 85 being released on the return movement of the rod 70.

Two pivoted members 2, 4 are clamped together by a pin or the like 5 passing through one member 2 and secured to or engaged through the other member 4, the pin 5 having at its free end a cam member 8, mounted on a transverse pivot 10, by which the members can be clamped together to lock them in a pre-determined position in which a longitudinal cutaway portion on at least one of the pivoted members engages with the other. In the embodiment shown the two members are tubes hinged together by means of the pin 5, the member 4 having an enlarged end of suitable form to embrace the member 2 when the two members are aligned, so that when clamped together they cannot be relatively moved. To assist in aligning the members a pin 11 is provided on the member 2 to engage with a hole in the member 4. In a modification, two shafts or bars are each cut away at the end to form a scarfed joint, clamped in the same manner so that the remaining part of the end of each shaft abuts against the end of the cut-away in the other. The cams 8 are preferably duplicated on either side of the pin 5, with a single handle 9.

Two gas flow paths are provided, one through the tubes and the other to and fro across the tubes in a direction substantially at right angles to the axis of the tubes. In Figs. 1 and 2 exhaust gases from the turbine 4a pass through the duct 4 to an annular header 3 around the upstream end of the combustion chamber. The gases pass through the tubes 6 and discharge at 15. Air from the compressor 9a passes through a duct 10 to a header space 9 between the downstream end wall of the combustion chamber 5 and the tube plate 12, the air then being caused to flow to and fro across the tubes by means of the transverse baffle plates 13, 14 finally reaching the annular space around the upstream portion of the combustion chamber. The heated air enters the chamber through swirl vanes 19 and ports 21, 17, and the combustion products pass through duct 11 to the inlet of the turbine 4a. The heating apparatus 6a may be disposed below the floor level 23. The invention may be applied to a hot air turbine plant in which air from a compressor is heated in a heat exchanger before passing to the turbine, the air exhausting from the turbine entering a combustion chamber, the combustion products from which pass through the heat exchanger. In this embodiment, the air to be heated passes through the tubes of the heat exchanger and the' products of combustion from the combustion chamber flow to and fro across the tubes before discharging to atmosphere.

The other end is fastened to the chains through the medium of the springs 15 and tension-adjusting members 16, 17. Projections 18 carrying flexible rubber strips 19 prevent material escaping at the sides of the rubber sheet. Light inter mediate chains parallel to the chains 1 may form additional supports for the transverse members 8 when necessary. Driving the chains causes the member 7 to push the load off the vehicle ; the rubber strip passing to the underside of the sprockets during the process. Many modifications in detail are described, including the omission of the member 7 and the making of the rubber sheet endless or to roll up on a roller, and various methods of securing the rubber sheet to the chains.
