摘要： 832,751. Knitting. COTTON Ltd., W. June 26, 1956 [July 1, 1955], No. 19116/55. Class 74 (2). In the successive production, on a straightbar machine, of knitted fabric portions from the same yarn, each of which portions is pressed-off after completion, the yarn Y extending obliquely from its carrier 5 to the selvedge of a contracted, finished and pressed-off blank on the take-up roller 1 is pulled into a direction YP normal to the needle line and swung down between two adjacent sinkers by a hook 9 adjustably carried on a rod 6 which, by means of a handle 11, can be reciprocated axially, between limits determined by an abutment 12 on the rod and fixed and adjustable stops 13, 16, and oscillated about its axis between limits determined by the cooperation of stops 17, 18 with two faces of the template rail 8. The yarn is thus clear of the points 4 of a point bar 3 as they are advanced to the needles to transfer thereto a length of rib fabric RF in extension of which the remainder of a new blank is to be knitted from the yarn Y. When, as in intarsia or plated work, a plurality of yarns extend from the last blank, a plurality of hooks is used. These hooks may be mounted on a common bar, all the yarns being secured to a cleat at one side of the machine section. When the inclinations of the yarns demand it, the hooks may be in two sets, facing in opposite directions and mounted on two bars 47, 48, the hooks being appropriately located on the rods relatively to such yarns as required to be pulled one way or the other to bring them normal to the needle line. The rod or rods may extend along the length of a multi-section machine, the controls being situated in, or in the region of, an intermediate non-knitting section. Specifications 763,591, 797,871 and 813,435 are referred to.

摘要： 772,737. Knitting-machines. COTTON, Ltd., W. April 28, 1955 [May 1, 1954], No. 12700/54. Class 74 (2). An electrical circuit controlling the electric motor of a straight-bar machine, has switches 3, 4, 5 associated with the racking mechanism for the narrowing points or selvedge stops. Another switch 9 is associated with the narrowing frame 26 and is normally held open by the frame when it is in its raised inoperative position. Assuming that the narrowing points are correctly aligned with the needles, the switches 3, 4, 5 which are controlled by the indexing mechanism 10 through levers 12 are closed and upon operating a power rod to start the machine, switches 2 and 1 are closed in turn such that current flows from line A through switches 3, 4, 5, normally closed switches 6, 7, 8, and switches 2, 1. From the switch 1 the current passes through press-button stop and overload switch M to energize contactor coil K which causes contactor G to close to enable current to pass to the motor. Simultaneously, retaining switch HJ is closed to maintain the coil K energized and to retain the contactor G closed. the power rod being returned slightly to open switch 1. Prior to narrowing or selvedge stop adjustment the narrowing frame 26 is lowered, thereby closing switch 9 and retaining the circuit closed whilst the subsequent narrowing and selvedge stop adjustments are made during which time the switches 3, 4, 5 are momentarily opened. If, however, the narrowing mechanism or selvedge stops are incorrectly positioned, one or more of the switches 3, 4, 5 remains open such that upon the narrowing frame 26 returning to its raised inoperative position and opening its switch 9, the circuit becomes broken and the coil K de-energized. This action releases contactor G and breaks the supply to the motor such that the machine is stopped.

Class 74 (2) A device to stop or act to avoid damage to a machine in the event of a fault in a pattern chain, comprises a pivoted bar 8 having gates 9 through which studs 2 on the chain normally pass. Should a stud 2 be dis. placed or the chain be distorted, the bar 8 will be contacted and moved to operate the stop motion &c.

摘要： 746,387. Knitting-machines. COTTON, Ltd., W. July 3, 1953 [Aug. 30, 1952], No. 21856/52. Class 74 (2). To speed up the production of horizontally striped fabrics upon a straight-bar machine, yarn selection is effected during the knitting period of the course immediately preceding yarn change, and the speed of the machine is reduced during the latter part of the yarn draw period for that immediately preceding course and is restored to normal during an early period of the yarn draw period for the course in which yarn change occurs. Yarn selection and speed control are both determined by stops 34 ... 36 upon a common pattern chain 37, but the actual timing of the yarn change and the change of speed is controlled by cams 23, 54 upon the main shaft so that these times are related to the yarn draw and knitting periods of the machine. As described in connection with a machine having three carrier bars 1 ... 3, the bars are selectively operable by a bolt 4 mounted upon a rocking shaft 5. The shaft 5 is rocked to bring the bolt 4 into alignment with a bar 1 ... 3 under control of three star-wheels 13 ... 15 having lugs of different height and secured to ratchet-wheels. The ratchet-wheels can be intermittently rotated by pawls actuated by the cam 23, and a pawl bluffing member is provided for each ratchet-wheel and is moved under control of a pattern stop 34 ... 36 to permit the corresponding star wheel to be rotated, the rotation of the star wheel and, therefore, the rocking of the shaft 5 being timed by cam 23. Movement of any bluffing member is accompanied by movement of a rod 43 which by linkage 44 ... 49 frees a catch 50 from a roller 51 upon a truck arm 52 so that a truck 53 carried by the arm can engage the cam 54, which by means of linkage 152, 55 adjusts the brushes of the driving motor to reduce and restore the speed of the machine. One row of the studs 35 and an additional row of studs 137 may be provided for single-course striping.

摘要： 728,046. Knitting-machines; yarn supply. COTTON, Ltd., W. July 7, 1952 [July 5, 1951], No. 15938/51. Class 74 (2). At the lower end of a strip-like yarn carrier 1 a yarn feed tube 8 is removably held, by means or a squared or flat-sided part 10, against rotational and axial movement, in a cleft 9 which may be opened, to release the tube, by axial rotation of an oval section tool in the cleft. The exit end of the tube may be chamfered to cooperate with sinkers, or left square so that the tube may be rotated through 90 degrees, as necessary, to present a new wearing part to the yarn. The cleft 9 may taper and the narrow dimension of the tool be such as to ensure that it can be used only in the widest part of the taper. Specification 728,070 is referred to.
