24,163. Birkin, T. S., and Anderson, T. Nov. 11. Lace and lacemaking.-A lace fabric having clothing, combination, cross-net, and openwork effects is made on a curtain macbine by the use of four thread - guide bars and pickers or jacks selected by two single-lift jacquards. The bars e, f and g, h carry thick k spool warp and fine spool threads a, b, c, d respectively. On the front motion, the bars e, f, g rise two gaits before the jacks enter ; subsequently the bar e rises a further two gaits, the bar h rises one gait, and the bars f, g fall one gait before the carriages pass to the front, and on the back motion, the bars f, g rest while the bar e falls three and the bar h falls two gaits before the jacks enter ; the bars e, f, g then fall one gait while the bar h rises one gait before the carriages return to the front. Four-gait clothing A is obtained by holding the jacks in the position o clear of all the threads on both motions, commencing on a front motion. Combination work B is obtained by moving the jacks to the position p through the threads a, b on a front motion and holding them clear of all the threads on the back motion, the effect being commenced on a back motion. Cross-net C is produced by moving the jacks to the position r through all the threads for any consecutive front and back motion, and then to the piston p in a similar manner. For open-work effects, the jacks are moved to the position p for any number of consecutive motions.
