LOOM-SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 653,969, dated July 17, 1900.

Application tiled March 30, 1900.

To all whom it may concern:

Be it known that I, JAMES C. SERGEsoN, a citizen of the United States, residing in the city and county of Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvement in Loom-Shuttles, which improvement is fully set forth in the specification and accompanying drawings.

My invention consists of a shuttle which is provided withV means which by the motion lof the spindle may be automatically engaged with a bobbin and automatically disengaged therefrom.

Figures l and 2 represent top or plan views of a shuttle embodyingl my invention. Fig. 3 represents a side elevation thereof, a portion of the body of the shuttle being cutaway. Figi 4 represents alongitudinal section thereof. Fig. 5 represents a partial end view and partial transverse section on line a: Fig. 4.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A designates a shuttle in general respects of usual construction.

B designates the spindle,0 the head thereof, and D the axis of said head.

E designates the jaws, which are mounted on said head by the pivot F, whereby they are permitted to open and close in the direction of the width of the shuttle. The heel or rear ends of the jaws are curved or tapering and have depending ears G, which freely enter the recesses H in the head C, so as to be guided therein as the jaws open and close. Interposed between said ears is the spring J,

whose tendency is to close the jaws and hold 4 them closed, said spring occupying the chaml ber K in the head C and bearing against the ears.

L designates shoes which are seated on the recess M in the head C,V said recess being par-V allel with the recesses II and permitting the shoes to rock on said head. Bearing against the back of the connecting-piece N of the shoes is the coiled spring P, which rests freely in the nose or end portion of the body of the shuttle and encircles the stem L of the shoes L, thus retaining the shoes in position on the head C. The shoes are adjacent to the heel ends of the jaws E and have their inner sides Q preferably inclined or converging, said heel Serial No. 10,744. (No model.)

-dle is lowered and returned, the heel ends of the jaws then clearing the shoes L and the spring J becoming operative and separating the heel ends of the jaws, whereby the latter close on the bobbin and tightly clamp and hold the same. The spring P, which in a measure works with the shoes L, now presses upwardly against the wall of the recess N and so holds the spindle in closed position. In

(order to release the bobbin, the spindle is raised, when the heel ends of the jaws enter between the shoes L and are brought together, whereby owing to said heel ends or heels, which are curved or tapering, the jaws separate and are removed from the bobbin, the latter thenbeng free to be slipped off of the spindle.

The jaws are angular or deiiected and have curved faces, so as to nicely enter the groove of the bobbin and properly engage with the wall thereof.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A shuttle having pivotal jaws mounted on the head of the spindle thereof and shoes on the body of the shuttle between which the heel ends of^said jaws are adapted to ride, and a spring bearing outwardly against said heel ends,whereby when the spindle is raised said jaws automatically leave the bobbin on said spindle and when said spindle is lowered, said jaws automatically close on said bobbin.

2. A shuttle having pivotal jaws on the i head of the spindle thereof and shoes between whose inner faces the heel ends of the jaws are adapted to ride, whereby, when the spindle is raised, the jaws are automatically disengaged from the bobbn.

3. Ajshuttle having laterally-movable jaws pivoted on the head of the spindle thereof and adapted to embrace a bobbin, and a spring bearing laterally against the heel ends of said jaws, whereby when the spindle is lowered, said jaws automatically engage said bobbin and retain their hold thereon.

4. A shuttle having pivotal jaws on the head of the spindle thereof and shoes on whose sides the head ends of the jaws are adapted to ride, whereby when the spindle is raised, the jaws are automatically disengaged from lLhe'bobbin, and springs bearing laterally against said heel ends, whereby when the spindle is lowered, said jaws automatically close upon said bobbin.

5. In a shuttle, a spindle, a head carrying the saine, laterally-movable jaws pivoted on said head, a spring bearing laterally against the heel ends of said jaws, shoes mounted on said head and adapted to engage said heel ends when the spindle is raised, and a spring on the shuttle engaging said shoes and serving to hold the shoes on the head, and retain the spindle either in open or closed position.

6. In a shuttle, a spindle, a head carrying the same, jaws mounted on said head adapted `t0 engage a bobbin on said spindle, and a spring bearing against the heel ends of said jaws to close the latter, said heel ends having depending ears and said head having recesses which freely receive said ears.
