NITED STATES MARY F. BURROUGHS, OF MARSHALL, MISSOURI.

SEWING-MACHINE SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 606,443, dated June 28, 1898.

Application filed May 11, 1397- Serial No. 636,028. (No model.)

To all whmn it may concern:

Be it known that I, MARY F. BURROUGHS, of Marshall, in the county of Saline and State of Missouri, have invented certain new and useful Improvements in Sewing Machine Shuttles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. i

This invention relates to improvements in sewing-machine shuttles; and the same has for its object to provide an improved shuttle in which the spool of thread may be placed directly without the necessity of winding the cotton therefrom upon a bobbin, as in the ordinary construction of shuttle.

The invention consists in the details of construction hereinafter fully described and claimed, and illustrated in the accompanying drawings, in which- Figure 1 is a perspective View of my improved shuttle in position within the shuttlecarrier provided therefor. Fig. 2 is a perspective view of the shuttle-carrier with the shuttle removed therefrom. Fig. 3 is aview of the shuttle with the door opened to show the spool in position therein. Fig. sis-an end view.

1 indicates a shuttle-carrier, one end of the same turned at right angles to form the back wall, against which the end of the shuttle is adapted toabut, and having a portion of its side wall also turned up to form a guide for the shuttle. The forward end of the carrier is turned up at 2 to be out of the way of the loop of thread formed by the descending nee- The turned-up end 20f the case also assists in holding the shuttle in proper posi-. tion therein by engaging the front portion thereof, and the said case as an entirety is adapted to be carried by a reciprocating arm coacting with a raceway, all of which is well known in the art to which this invention appertains.

The shuttle consists of a circular casing 3, which is pointed at its forward end, as illustrated at 4, and has its rear end 5 hinged thereto, as illustrated at 6. A door 7 is pro vided, which is'hinged to the casing at its lower end and adapted to be secured at its upper end by the latch 8, carried by the casing. \Vhen this dooris opened, as illustrated in Fig. 3, accessmay be had to the interior of the shuttle-casing through the side and top wall thereof for the purpose of inserting the spool 9. A screw 10 passes through the outer wall of the casing and engages one of the ends of the spool, whereby the tension is regulated as desired.

The door of the casin g is provided with the usual V-shaped slot 11, through which the thread is passed, and upon the outer surface of the door is a spring-guide 12, having its central portion looped, as illustrated at 13, said guide being for the purpose of receiving the thread after the same has been passed through the slot, the thread working beneath the looped portion thereof.

In operation the door is opened and the spool inserted within the casing, the hinged end wall of the same -greatly facilitating the insertion of the spool, and the thread is in sorted through the V-shaped slot. The door is then closed and secured by the latch and the thread placed beneath the guide provided therefor. The shuttle is then inserted in the casing, the end wall of said casing or holder preventing the movement of the hinged end of the shuttle. The thread in then passed beneath the hook upon the casing or holder, which serves to guide the same.

From the above description it will be seen ready for sewing without the necessity of removing the spool or shuttle. This is a great advantage in that time and labor are saved the operator.

Having thus fully described the invention, what is claimed as new, and desired 'to be secured by Letters Patent, is

1. A shuttle, comprising a casing rounded threaded in the door, and the machine is again to conform to the contour of the spool of thread, one of the end walls of the casing being hinged thereto, the opposite end being pointed, a door hinged to the casing by means of which access may be obtained to the interior of the casing for inserting the spool of thread therein, means for securing the said door in a closed position, said door being provided with a slot through which the thread is adapted to be passed, a guide upon the exterior of the door for holding and guiding the thread, and a screw adapted to be passed through the casing and bear at its end upon the spool to regulate its rotation, substantially as set forth.

2. The combination of a shuttle-carrierprovided with a guiding side wall and an end wall, a shuttle comprising a casing having its end wall hinged thereto and its opposite end pointed and adapted to be positioned within the said shuttle-carrier, a door for the shuttle by means of which access is obtained to the interior thereof, a latch whereby said door is secured in closed position,ia springguide upon the door for directing the thread from the said shuttle, and a tension device by means of which the rotation of the spool of thread is regulated, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
