SPECIFICATION formingpart of Letters Patent NO. 366,296, dated July 12, 1887.

Application filed January 22, 1887. Serial No. 225,223. (No model.)

To all whom it may concern.-

Be it known that 1', JAMEs T. BONNEY, a citizen of the United States, residing at New Bedford, in the county of Bristol and State of Massachusetts, have invented a new and useful Improvement in Tension-Regulating Devices for Loom-Shuttles, of which the following is a specification.

The object of my invention is to produce a simple, cheap, and easily-operated device by means of which the tension on the thread from the shuttle may be perfectly regulated. I attain this object by the device illustrated in the accompanying drawings, in which Figure 1 is a side elevation of my tensionregulating device. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a View of the wrench by means of which the tensionregulating device is operated. Fig. 4 is a view in cross-section of the shuttle and ten sion regulating device on the line 00 w of Fig. 5. Fig. 5 is aside view of a portion of a shuttle, showing the educt and the tension-regulating device and spindle in dotted lines. Fig. 6 is a top view of the tension device.

In Fig. 1 2' represents my tension-regulating device, consisting of a plug of suitable material having its top flat and its bottom preferably rounded, and perforated vertically through its center, with the upper half of the perforation enlarged, and a perforation made in the center of its side to connect with the vertical opening, as is more fully shown in the sectional View of Fig.2, and a groove formed in its side reaching nearly its entire circumference, as is fully shown in Fig. 1.

In Fig. 2 c is the perpendicular opening, and a is the opening in the side connecting therewith. a n are perforations made in the top of the device in order that it may be operated by the wrench, Fig. 3; and b is the groove in the side. The tension-regulating device is seated in the shuttle, as shown in Fig. 4, which is a cross-sectional view of the shuttle through the center of the seat of the tension-regulating device. The tension-regulating device is held in its seat by means of the'bolt or rivet e, which is riveted on the outside of the shuttle at g. The tension-regulating device is seated in the shuttle in such a manner that the opening a shall coincide with the educt r, in order that the thread from the spindle may be unobstructed in its passage through them.

In Fig. 5 is shown a portion of a shuttle with the spindle and tension-regulating device in dotted lines, and the thread t protruding from the educt r.

The operation of the device is as follows: When it is desired to put a certain tension on the thread, the tension-regulating device is turned in its seat by means of the wrench in such a manner that thethread in passing from the spindle 8 through the openings 0 and a and out through the educt 1 will be made to pass around agr'eater or less portion of the circumference of the groove b. Thus it will be seen that by means of this simple and cheap tension-regulating device the tension on the thread from a shuttle can be perfectly regulated to any desired extent.

, Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

In a loom-shuttle, the combination, with the shuttle body and spindle, of the adjustable plug 2', having a central vertical opening, 0 d, side opening, a, and groove 1), constituting a tension-regulating device, and the bolt 6, for securing Said device in its seat, substantially as shown and described.
