Improvements in Shuttle Guards for Looms.
Реферат: 19,588. Grayson, J. Aug. 25. Loom shuttle guards.-Relates to guards having cranked parts b by which they are pivoted. Near one of the cranks is secured a bracket c with a projection c', by which the guard is held in the operative position. In Fig. 1 the projection is shown with an incline c<2> and recess c<3>, while in Fig. 3 the projection is shown formed with a rounded face c<2>. In this latter case the guard can yield inwardly, preventing trapping of the fingers. A spring is provided to hold the crank in contact with the projection. A cord attached to the guard may be connected to the fork lever or other part so that the guard is placed in the inoperative position when the loom is stopped; or the cord may be connected with a treadle.
