- `My invention consists firstly in an im#` proved anode of applying the spring` catch which is employed to `conline thebobbin in bobbin shuttles,fwhereby it adaptsitself to `the varying sizes of the heads ofthe boblbins, and` is caused to be drawn oli the bobbin heads squarewith the spindle so as not to drag` upon and split the heads likeit does This improvementalso enables the catch to to conne the tin tube: on which the fcop is spunor to confine'the cop if it is spun without thetintubey H Y A, is the body of the shuttle.

\ `bei best understood by reference to Fig. l.

It is attached "to a pin e, which passes upward through the spindle perpendicularly to the, axis thereof and fits to work freely therein, and it is furnished with a head f, between which and the spindle, a spiral spring g, is coiled around the pin, for the purpose of holding' up the catchinto the notch in the head of the bobbin. l e

D, is a metal plate secured to the body of y l the shuttle in such a position that as the Figure l, is a'` longitudinal section of a point of the spindle a, is raised, the head (f) of the pin of the catch comes in contact with it and is by it arrested so that asthe rising` of the spindle continues, the catch is thrown out of the notch in the bobbin head and the bobbin is set free, as is illustrated by the red outline in Fig. l. The plate D. also serves to confine the main spring.

The catch C, shown in Fig. 3 to confine the co-p is made with a small notch z', to receive the collar of. the tin tube j, and is formed with a point which if the tin tube is not employed will catch the cop and confine it.

It will be readily understood that as the pin e, of the catch moves with the spindle, and is perpendicular thereto, the catchmust be drawn oi the bobbin square Without dragging' endwise on the head.

.e `What I claim as my invention and desire to secure by Letters Patent, is-

Attaching the catch C, which confines the bobbin or cop on the spindle to a pin e, which works perpendicularly through the spindle, and is acted upon for the purpose of throwing and holding the catch in operation by aspiral spring g, or its equivalent, and acted upon for the purpose of throwing the catch out of operation, by coming in contact as the spindle is raised, with a plate D, or other iiXed stop, the whole operating substantially as described for the purpose se forth.
