SHUTTLE FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 549,265, dated November 5, 1895. Application filedJ'une '7, 1894. Serial No. 513,728. (No model.)

To all whom it may concern:

Be it known that I, HENRY A. BATES, a citizen of the United States, residing at Yonkers, in the county of Vestchester and State of New York, have invented an Improvement in Sewing-Machine Shuttles, of which the following is a specification.

The object of the present invention is to connect the case that holds the bobbin of thread with the revolving or oscillating shuttle, so that the cover of the bobbin-case can be removed for the insertion of a fresh bobbin of thread and replaced and held by friction, the thread itself of the bobbin being sup ported between the back plate or disk of the case and the movable cover, and the case can remain stationary as the thread is drawn off, because the shuttle-hook can be revolved or oscillated freely while the bobbin-case is held to the central pin.

In the drawings, Figure 1 represents a shuttle-hook with the case removed. Fig. 2 shows the inner side of the bobbin-case; and Fig. 3 is a vertical section of the parts at the line so a: of Fig. 1, the bobbin-case being shown in position.

The shuttle-hook B is of any desired size or shape. The shuttle-hook represented in the drawings is well known in the trade, and it contains a central pin 0, which is usually tubular, so as to lessen the weight.

The bobbin-case A is adapted to receive within it the bobbin of thread, which is usually wound upon a short paper tube, and in shuttles of this general character the case A has confined the bobbin of thread between Its own inner surface and the flat side of the shuttle; but in this arrangement the vibration or rotation of the shuttle and hook has tended to injure the thread and increase the liability of the same becoming entangled around the center pin. To avoid the beforementioned difficulty, the disk D is provided, and it has a short central tube r, that surrounds the central pin 0 and turns freely thereon, and there is a holding-collar s, that projects from the central pin 0 at the endof the tube 0". This holding-collar s is represented as provided with a tubular extension passing into thepentral pin 0, which is tubular; but the holding-collar s will be made according to the character of the central pin 0, the object of such holding-collar 8 being simply to hold the disk D and its tube 1 upon the pin to allow them to turn freely upon such central pin 0.

The bobbin-case A is usually provided with a projecting arm, as seen in Fig. 2, and with a spring, beneath which the thread is passed, so that the projecting arm holds the bobbincase from revolving or turning as the shuttle is either rotated or oscillated, and this bobbin-case A has a central tube 6, which is of a size to set around outside of the tube 1", and such tube 6 is split, so that it may spring and accommodate itself to the tube 4' and be passed on or off with facility; but the parts will hold together sufficiently for properly retaining the bobbin of thread within the case and between the same and the disk D, and it will now be understood that the two parts A and D of the bobbin-case are held together by friction to properly support the thread of the bobbin, and the rotation or oscillation of the shuttle-hook does not in any manner affect the thread itself of the bobbin. Hence such thread will draw off as the sewing progresses with greater uniformity of tension than heretofore, and the thread will not be liable to become injured or entangled around the central pin of the shuttle, and the bobbin-case is retained in its proper position relatively to the shuttle-hook.

I claim as my invention- The combination with the shuttle having a central pin, of a disk D and integral tube 0' surrounding the central pin of the shuttle and movable freely thereon, a holding collar for confining the tube and disk in position and the bobbin case A having a central split tube e to surround the tube 1" and hold by friction thereon, substantially as set forth.

Signed by me this 4th day of June, 1894:.

- HENRY A. BATES.
