IMPROVEMENT IN SHUTTLES IEGR LOOMS.

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

To all whom it may concern Beit known that I, NORMAN A. WILLIAMS, of Utica, in the county of Oneida, and State of New York, have invented a new and useful Improvement in Shuttles; and I do hereby declare that the following is a full, clear, and exact description thereof, `which will enable those skilled Vin the art to make anduse the same, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to improvements in shuttles for looms, whereby it is designed to provide an improved spring-mechanism for holding the spindle either in the elevated position for receiving thevbobbin or cop, or in the position for delivering the yarn in weaving, and admit of moving it readily from one' position to the other.

The accompanying drawing represents a longitudinal `section of a shuttle having my improvements attached.

a represents the spindle pivoted at b, and provided with the rear extension c, which may be of any preferred length, Itothe rear of which the bent spring d is secured by one end, the other hooked end being ar ranged `to take into the, notched end of the toggle-arm e, arranged to oscillate on the pin j, or any other suitable seat, as,.for instance, a socket in the stock of the shuttle. V Y

The chamber in the stock of the shuttle is so formed that the upper wall g,.andrthe inclined wall h, below d is under the greatest tension when the toggle-arm e is on the right line, between its axis f and the axis h of the spindle, and consequently will have a tendency to force the toggle-arm and the spindle in either direction from that line, as it 'may be passed to either side of it by the operator, and will..theref`ore maintain the spindle in either position.

An important advantage of this arrangement is that there are no sliding parts, which soon wear, and produce undue friction, as in other shuttles.

l represents a catch-spring, for holding the bobbins, also secured to the extension of the spindle, and provided With a; hooked end, to take into the grooves in the hase of the said bobbins, and arranged to be thrownv out of connection therewith lwhen the spindle is raised up by the action of the pin m, as is clearly shownin the drawing.-

The said spring l may be dispensed with when cops are used.

. OareshOuId bev taken inadjustin g the walls g and k,

for stopping the toggle-arm, and the extensionbf the spindle in the right position for maintaining the spindie inline with the eye of the shuttle through which the yarn is drawn.

I claim as new, and desire to'secure by Letters
