IMPROVEMENT m SHUTTLES FOR SEWING-MACHINES.

The Schedule referred to in these Letters Patent and making part oi the same.

To all whom it may concern:

Be it known that I, WALTER BENNETT, of Springfield, in the county of 'Sangamon and State of NH- nois, have invented a new and nsefnl' Improvement in Shuttles; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being. had to. the accompanying drawing forming part of this specification.

' This invention relates to improvements in shuttles, and consists in an improved arrangement with the shuttle,"having a recess ,or depression along the upper edge of one of the sides of a bar, with eyes for the thread and slots leading from the lower edge to the said eyes, for threading tliem,'said bar beingw piv. oted atone end to the shuttle inside, and arranged to close down by the inside 'ofthe recessed side so that the thread will be retained in the eyes by the upper edge of the shnttle side.

The said improvement is mainly designed for sewing-machine shuttles, but may be applied to others.

Figure l is a perspective viewof "my improved shuttle, with the eye-bar raised, and v Figure 2 is a side elevation of the shuttleuvhen the bar is closed down to the working position. Similar letters of reference indicate corresponding parts.

A is the shuttle, of ordinary construction, except that the depression, B, is made in the upper edge of the wall over which the threadpasses.

C is a. long flat bar of sheet metal, having a number of eyes, D, through it, and slots E leading fronr the lower edge to the eyes.

This bar is pivoted tot-he shuttle inside the wall, having the recess at one end thereof; and so that it may shut. down inside the said wall till the eyes will range along above the wall, as shown in fig. 2, the slots falling below, sothat the thread-is confinedv in the eyes by the wall of the shuttle.

To thread the shuttle, the bar 0 is-raised, as shown in fig. 1, and the thread is drawn across the lower edge and along it lengthwise, until itencounters the slot leading to the eye, into which it is designed to have it fall when the tension on the thread carries it; through the slot to the eye. The upper edge of the bar comes down flush with the top of the shuttles.

Having thns'descrihed my invention,

I claim as new and desire to secure by Letters Patent The combination, with the shuttle, having the depressions in the wall over which the thread passes, of the slotted eye-bar 0, arranged substantially as specified. V

Witnesses: \VALTER BENNETT.
