UNITED STATES PATENT OFFICE.

IRA CROSS, OF NASHUA, NEW HAMPSHIRE.

SPECIFICATION forming part of Letters Patent No; 375,265. dated December 20, 1887.

Application tiled August 22, 1887.

To aZZ whom, it may concern.-

Be it known that I, IRA CRoss, of Nashua, county of Hillsborough, and State of New Hampshire, have invented an Improvement in Loom-Shuttles, of which the following def scription, in connection with the accompany on the spindle.

Prior to my invention a spindle having a shoulder to engagean inside groove has been provided with a long heel, upon which has been riveted a tlat spring to act against the periphery of the bobbinhead and press the bobbin upon the shoulder', and so, also, aspindle has been provided with a piu carrying a presser to act on the periphery of the bobbin.

In my invention the long heel for the spindle and its attached spring are omitted, and instead I employ a stationary pin,which arrests the head of the bobbin just before the spindle comes into central position in the shuttle-body, the arrest of the bobbin enabling the shoulder at the under side of the shuttlespindle to enter the inside groove. j

Figure 1, in longitudinal section, shows a shuttle embodying my invention, the spindle and shuttle being in working position; and Fig. 2 is a like view,with the shuttle and bobbin, but partially shown, turned out of the shuttle-body.

The shuttle-body A is and may be of usual construction.

The spindle B, pivoted onv a pin, B, has at its under side a shoulder, b. The bobbin C has at the inner side of its base an inside` groove, c.' The short bed b2 of the head ofthe spindle is acted upon by a plunger, d, in turn acted upon by a spiral spring, d', the plunger acting to hold the spindle in the two positions Serial No. 247,553. (No model.)

bin strikes against the arresting pin or projectione just before the spindle reaches its proper central position parallel to the center line ofthe shuttle-body, and as a result thereof the head of the bobbin is arrested before the movement of the spindle is completed about its pivot B', and the collar or projection b is made to enter the inside groove of the bobbin.

The construction herein shown is simpler and cheaper than anything known to me capable of accomplishing a like purpose.

Prior to my invention I am aware that a bobbin having an outside groove has been retained upon a spindle by means of a stationary pin which was embraced by the said groove when the bobbin and spindle were turned into the shuttle-body.

I claim- Theshuttle-body, the bobbinreceiving spindle having a shoulder, b, at its under side, combined with an arresting piu or projection,

' e, secured to the shuttle-body and acting to arrest the bobbin held upon the spindle just in advance of the arrival of the said spindle in central position in the shuttle-body, substantially as described.

In testimony whereof I have signed my name to this specification in the' presence of two subscribing witnesses. 1
