SHUTTLE FOR Looms.

SPECIFICATION forming part of Letters Patent No. 378.895, dated Marche, 188s,

` Application tiled September 26, 1887. Serial No. 250,717. (No model.)

.To all whom it may concern: y

Be it known that I, GUY C. MILLS, of Nashua, county of Hillsborough, and State of New Hampshire, have invented an Improvementin Shuttles for Looms, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object to improve and simplify the construction of that class of shuttles wherein the bobbin is held upon the spindle by an inside catch.

In this invention the groove within the bobbin is engaged by a projection from one side ofthe spindle, and also by a lip of a springcatch located at the opposite side of the spindle, as will be described.

My invention consists, essentially, in the combination, with a spindle-body and bobbin having an internal groove, of a spindle having at one side a bobbin-engaging projection, and with a locking spring having alip to enterthe groove at the inner side of the bobbin, but at the opposite side of the spindle.

Figure l shows in longitudinal section a part ot' a loom-shuttle embodying my invention, and Fig. 2 is a modification to be described.

The shuttle-body A has pivoted to it at a a spindle, cf, having at one side a projection, as a3, to enter the inside groove, b, in the bobbin b, (shownv by dotted lines,) the projection acting to retain the bobbin on the spindle, all as usual. The spindle is acted upon by aspringpressed pin, c, which lnormally keeps the spindle down in the shuttle-body. The heel of the spindle has riveted to it aspringcatch, d, having a lip, d2, which enters the chambered base of the bobbin, and engages the inside groove therein at that side of the spindle opposite the projection a3.

The shuttlebody has a pin, e, so located as to be struck by the spring when the spindle is turned out of the shuttle-body, as in dotted lines, Fig. l, the pressure of the spring against the said pin pushing the lip of the springcatch back out of the inside groove iu the bobbin.

As described, it will be seen that the bobbin is held positively atits interior at two points and at opposite sides of the spindle, thus holding the bobbin very securely.

In the modification shown in Fig. 2 the inside catch, d, having the lip d2, is attached to a shank, h, extended through a hole in the head of the spindle, the shank being surrounded by a spring, as h, the lower end of the shank being sufciently upset or enlarged, so as to limit the outward movement of the lip.

In practice, when the spindle is turned ont from the shuttle, the head of the stud will hit against a shoulder, as 7a3, in the wood of the shuttle-bobbin. (See Fig. l.)

I claim- The shuttle-body, the spindle provided with the projection as at one side, to engage au inside groove in the bobbin,and an independent spring-catch, d, located at the opposite side and attached to the heel of the spindle, the said springcatch having at its free end a lip, to also enter and engage an inside groove in the base of the bobbin, combined with means to operate the said spring-catch to relieve the bobbin when the spindle is turned out of the shuttle-body, substantially as described.

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

GUY C. MILLS.
