PURPOSE:To secure certain operation of a dog member in the case when the direction of transfer of a shuttle frame is changed, by obtaining the revolution of a chain sprocket acting as a dog operating member through the reciprocative movement of the shuttle frame. CONSTITUTION:A chain sprocket 10 and a dog member 9 are press-fitted onto each side-suface by the expanding elastic force of a spring 15, and the revolution of the chain sprocket 10 is transmitted to the dog member 9 through the frictional force generated by the above-mentioned press-fitting. Therefore, as the chain sprocket 10 revolves in the case when shuttle frames 5 and 5 perform the advance movement, also the dog member 9 turns, and further the dog member 9 turns in the reverse direction, in case of retreat movement of the shuttle frame. While, as a stopper 12 is inserted into the dog member 9, which stops its turning in the engaged state with the stopper 12, and only the chain sprocket 10 continues revolution thereafter. |
