Abstract

406,230. Loom warp stop - motions. NIEMI, K. H. A., Hyvinkõõ, Finland. Sept. 30, 1933, No. 26977. [Class 142 (i).] Each lamina 3 of a warp stop-motion is provided with two holes 4, 5 through each of which one or more warp threads are passed, so that if one thread breaks, the lamina is supported only by the thread or threads in the other hole and relative movement between the lamina and a feeler 9 causes the lamina to assume an inclined position to effect the stopping of the loom by electrical or mechanical means. As shown, the lamina 3 of arcuate form, is arranged between supports 16, 17 for the warps and is provided with a projection 6 having limbs 7, 8 adapted to make contact with a bar 14 insulated from a carrier 9, 10, 11. The carrier may be stationary or be moved up and down to cause engagement of its projections 12, 13 with the lamina. When a warp thread breaks, the difference in the pressures everted by the projections 12, 13 is sufficient to cause the lamina to turn so that an electric circuit is completed through the bar 14 and one of the limbs 7, 8. If both threads break, the larger limb 8 causes the lamina to turn. A projection 18 on the lamina is adapted to engage on its upward movement with a projection 19 on the warp support, to counteract the turning effect of the warp friction in the holes 4, 5. Fig. 4 shows the method of threading two warps through one hole of a lamina. Neither thread breaks, the tension on the other is reduced, and the lamina turns.
