SHUTTLE.

Specification of Letters Patent.

Patented Feb. 6, 1906.

Application filed June 21, 19GB. Serial Nc- 266.199.

To LEZ whom t may concern:

Be it known that I, EDUARD Hnnzre, a citizen of the United States, and a resident of West Hoboken, Hudson county, State of New Jersey, have invented certain new and useful Improvements in Shuttles, of which the following is a specification.

My invention relates to shuttles such as are used in looms; and it consists in the novel construction and arrangement of parts, as will be hereinafter described, the features of novelty being pointed out in the appended claims.

Reference is to be had to the accompanying drawings, in which- Figure 1 is a face view of a shuttle constructed accordin to my invention. Fig. 2 is a detail sections. view of the spool-support, and Fig. 3 is an elevation thereof.

A is the body of the shuttle, provided with the usual rack B and having arecess or chamber C. A second recess or chamber D is arranged within the chamber C and contains two pivoted sprin -arms E' and F,provided with eyelets E an F and constituting a tension device. This part of the shuttle may be of any ordinary construction and part of the resent invention. support or ro Gr bottom C of the chamber and is provided with a sleeve H, which in the present instance is somewhat shorter than the rod G, A coil-spring I is arranged around this sleeve and has its one end secured thereto at J and its other end fastened at K, the coils of said spring I becoming wider apart as they near t e free end of the sleeve H. The object of this construction will become a parent from the description hereinafter. spool L is provided with a pin M arid carries the thread which passes from the s ool L down throu h the rod G, through diie eyelets E and of the s ringarm E and F, and through eyelets the shuttle. An arm Q, pivoted at R, is arranged to swing across the free end of the rod G, the free end of said arm Q1 entering a notch S in the body of this shutt e when said arm is in position over the su port G. In operation the spool L- is place on the support G, the pin M engaging the upper coil of the s ring L. The said spool 1s then turned, t e coils of the springs acting as a screw-thread, serving to lock the pin M and A hollow forms no extends u Wardly from the and an opening P out of with it the spool in position on the support. The end of the spool does not engage the bottom C of the chamber (l when the spool is in position on the su iport, thus doing away with any friction etween the end of the spool and the bottom of the chamber during any rotation of the spool which might take place as la pull is exerted on the thread from any cause. It is to be understood that the thread leaves the spool in the same direction in which the spool is turned in lookin@ it to the support, so that any pull on the `thread will fasten the spool on the support more securely, it being understood that the spool L does not turn as the thread leaves it. The arm Q serves as an additional means to prevent the spool Jfrom leaving the su port.

With my device I obtain a sim le and efiicient device Jfor securing the spoo in position in the shuttle, which locking device is Hexible or resilient, and thus also serves as a device for equalizing the tension on the thread during the operation of weaving. By having the coils of the spring wider apart as the near the i'ree end of the sieeve H a quie locking of the spool with the support is secured, the coils of the spring acting as a steep screw-thread.

Various rnodications may be made without departing from the nature of my invention.

I claim and desire to secure by Letters Patent# 1. In a shuttle, a support, a coil-spring arranged around said support, and a spool adapted to be carried by said support and provided with a pin arran ed to engage said coil-s ring to lock the spoo to the support.

2. In a shuttle, a support, a spool ada ted to be carried b said support, and a resi ient member for loc ing said spool to the su port.

3. In a shuttle, a support, a spool a apted to be carried by said sup ort, and provided with locking means, an a coil-s ring engaging said locking means for loc ing said spool to the support.

4. In a shuttle, a support, a sleeve on said support, a coils ring around said sleeve, a spool adapted to e carried by said support, and a projection on said spool arranged to engage said coil-spring to lock the spool to the support.

5. In a shuttle, a support, a coil-spring around said support, the coils of said spring IOO beoomin Wider apart as they near the free end of t e su port, a s ool, arranged to be slipped over tiie free on of said support and provided with a projection adapted to enter 5 into en agement with the coil-spring et the point W ere the coils are Widest apart, to look the spool to the support.

In testimony whereof I have signed this specification in the presence of two subsorib ing witnesses.

WILLIAM REINDEL, THOMAS H. WALKER.
