Abstract: 15,548. Hughes, C. Aug. 31. Loom creel frames; pile, forming and cutting ; pattern chains, lags, etc.; stopping and starting mechanism. -Relates to looms for the manufacture of Turkey carpets &c., reference being made to Specifications No. 13,401, A.D. 1886, and No. 4260, A.D. 1891. Means are provided whereby the differently-coloured threads from which the tufts are formed are selected automatically, or by means of mechanism governed by a key-board similar to that of a type-writer. The threads are drawn from bobbins mounted in the frame through apertures 48 in a segment 47, which is pivoted at 49 and may be turned to a greater or less extent either by one or other of a series of key levers 40, or 'by the system of levers 148, 140. The pivot 141 of the lever 140 is raised and lowered a uniform distance at each revolution of the driving-shaft, and the free end of the lever is caused to engage with a series of pins 147, or with notches of varying depth in a plate &c., the result being that the segment 48 is rotated to a varying extent to bring the particular coloured thread desired opposite the tufting-mechanism. The segmental plate 47 may have more than one row of apertures, or more than one plate may be used. means being provided, comprising a special key similar to 40, for bringing one or other of the plates into action as desired. The driving-shaft of the tufting-mechanism is driven through a catch arrangement, which is operated through a lever each time one of the levers 40 is depressed or the lever 140 actuated, whereby the driving-shaft is rotated and continues to be rotated until the key lever is raised &c. The pegs 147 of the pattern mechanism are shown arranged in sets around a shaft 150 ; they may, however, be secured in lags mounted on endless chains, which can be rotated by hand or automatically to bring a new set of pins into operation after each traverse of the tufting-mechanism across the loom. The tufting- mechanism is mounted on a carriage 1, which is traversed intermittently at the end of each tufting operation by worm and rack gearing, means being provided for reversing the motion of the carriage at each end of the traverse, so that the tufting operation may proceed continuously during both the backward and forward motion of the carriage. The segment 47 having been turned into the position required to bring the particular coloured thread desired opposite the feeding-nippers, the latter draw the proper length of thread from the bobbin and lay it across a couple of warp threads 4, when it is severed by a pair of pivoted shears. The thread is then held in position by a pair of spring jaws 76, 77 ; the ends are pressed downwards by a pair of plates or jaws 70 on the outside of the pair of warp threads, and after being pressed together are gripped by a pair of tweezers 17, and drawn upwards between the two warp threads, and so secured in position. The tweezers 17 are pivoted at 19, and operated by the cam and lever mechanism shown, one of the jaws being caused to open and close in the manner desired as the tweezers are inserted and withdrawn. When a complete row of tufts has been inserted, the carriage 1 carrying the tufting-mechanism is raised, to allow of the insertion and beat-up of the ordinary weft.
