Abstract

439,705. Loom dobbies. BLACKBURN LOOM & WEAVING MACHINERY MAKING CO., Ltd., and WATSON, E., Phoenix Iron Works, Blackburn. Sept. 6, 1934, No. 25623. [Class 142 (i)] The draw knives A<1>, B<1> of a dobby are actuated by cams A, B which receive an oscillatory motion from the draw bolts C extending from the T lever, each cam being formed with a dwell portion a<1>, an operative portion a<2> and a hook release portion a<3>. Each cam is pivoted on a stud a or b, that can be moved to any one of three holes f, f<1>, f<2> in the dobby frame to alter the lift, and is connected to the draw bolt by an eccentrically mounted stud H having an arm h that can be secured to the cam in any one of three positions h<2>, h<3>, h<4>. The draw knives are fitted with bowls E which are held in contact with the cams by springs c on the draw bolts bearing against guide brackets c<1> on the knives.
