HENRYC. BAILEY, OF NEW YORK, N. Y., ASSIGNOR TO THE GOLD MEDAL SEWING MACHINE COMPANY, OF ORANGE, MASSACHUSETTS.

SEWING-MACHINE SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 244,106, dated J'u1y 12, 1881.

I Application filed March .26, 1881. (No model.)

1' 0 all whom at may concern Be it known that I, HENRY C. BAILEY, of New York, county of New York, and State of New'York, have invented an Improvement in Sewing-Machine Shuttles, of which the followin g description, in connection with the accompanying drawings, is a specification.

This invention relates to sewing-machine shuttles, and has for its object to simplify the construction. thereof and facilitate threading, and retain the parts together when inserting or running a bobbin.

In this my invention the heel of the shuttle is permanently hinged to the body of the shuttle, and is held closed to keep the bobbin in the shuttle-body bymeans of a finger or lip at the end of the tension-regulating spring.

Figure 1 represents, in side elevation and partial section, a sewin g-machine shuttle showing my invention; Fig. 2, a top view of Fig. 1, with the heel turned out, and the tension spring swung aside to permit the heel to be so turned out and the shuttlethread to be applied into the guiding-eyes in the body of the shuttle; Fig. 3, a modification; Fig. 4., a section of the heel part shown in Fig. 3; Fig. 5, a detail of the end of the lip of the tension-spring shown in Fig. 3; and Fig. 6 is a modification to be referred to.

The shuttle-body A is of the class known as bored.

The outer journal of the bobbin is acted upon and held by the heel b, pivoted at b to the shuttle-body, so as to be turned up to close the open end of the bored shuttle-body, as in Fig. 1, or be turned out and down to uncover it, as in Figs. 2 and 3. This heel is held up in place to close the shuttle by means of the lip or finger 2 of the tension-regulating spring C, the front end of which is adjustably held upon the shuttle-body by thetension-regulatin g screw 01.

The finger 2 has a projection, 3, which enters a hole in the heel b, so that the outer end of the tension-spring cannot rise as the screw (1 is being turned down into the shuttle to in'-- crease the pressure of the spring 0 on the shuttle-thread extended on the body of the shuttle, as in Figs. 2 and 3. The spring C, with the projection 3, when released, will assume the dotted-line position shown in Fig. 1, when it may be readily turned aside, as in Figs. 2 and 3, and the heel may be turned out, as in those figures. The heel, being connected with the shuttle-body, cannot be lost, and. no time is wasted in putting the heel into and out of connection with the body, as when the heel is separate from thebody.

The body of the shuttle which I prefer to use will be provided with a V-shaped slot, n, to intersect the two thread-leading eyes 4 5, a large open space, 6, being made at the point of the V-shaped notch, as in Fig. 2, to enable the easy passage of the shuttle-thread f under-the point g.

The spring C is provided with a slit to form a finger, 8, the base of which extends to the thread-guiding eye 9, and the end of the said finger is turned down into a notch, 10, in the body of the shuttle.

In Fig. 3 I have omitted the V-shaped notch, and instead have made a straight slot, 12.

Instead of the projection 3, to hold the end of the tension-spring down orfixed while the screw (1 is being moved, I may shape the end of the spring C, as in Fig. 6, to enter a notch, m, made in the wall of the shuttle-body at its open end and overlap the hinged heel-piece b.

I claim- The bored shuttle-body and the heel hinged to it at the open end'of the body, combined with the screw 01 and adjustable tension-regulating spring, having the finger to hold the heel, and the projection to hold down the outer end of the spring, substantially as described.

In testimony whereof I have signed my name 8 5 to this specification in the presence of two subscribing witnesses.

HENRY C. BAILEY.
