Abstract

181,899. Wilmore, A. S. April 23, 1921. Addition to 171,632. Dobbies.-The dobby described in the parent Specification is modified by mounting the knifecontrolling rocking levers m on one shaft t, so that the two upper knives b will be drawn back together and the two bottom knives b' together. When a lifting-lever has to be given a double lift to form a top shed, a catch lever on the corresponding swing baulk is caused to drop on to the upper one of the knives b, or the lower one of the knives b<1>, which have longer strokes than the other two knives. This may be effected by means of a long pattern peg operating through the feelers and spring-controlled wires; or one feeler operated by a separate peg for each catch lever may be employed. The lifting-levers may be kept stationary in any one of the three positions for any number of picks.
