SHUTTLE.

Specification of Letters Patent.

Patented Oct. 10, 1916.

Application filed January 27, 1916. Serial No. 74,610.

To all whom it may concern:

Be it known that I, WILLIAM F. GOM- IsKY, a citizen of the United States, and a resident of Middletown, in the county of Middlesex and State of Connecticut, have invented a new and Improved Shuttle, of which the following is a specification.

My invention relates to the class of clevices above named, and an object of my invention, among others, is to provide a device of this kind having means to effectively support a bobbin in a manner to prevent the thread from sloughing off.

One form of device embodying my invention, and in the construction. and use of which the .objects herein set out, as well as others, may be attained, is illustratedin the accompanying drawings, in which Figure 1 is a side view of a shuttle embodying my invention, with parts broken away to show construction. Fig. 2 is a view looking at the shuttle from a point located at right angles to the point of view of Fig. 1. Fig. 3 is a view in cross section through the shuttle on plane denoted by dotted line 33 of Fig. 1, the bobbin being removed.

Fig. 1 is a detail view showing a slightly different construction of means for attaching the spring to the base.

In the operation of weaving, as is well understood, the shuttle is thrown with great force and is suddenly brought to a stop at each end of its path of travel with aresult that the thread must be wound securely upon the bobbin and the bobbin must be securely fastened in place to withstand such force, and in the uses of some kinds of thread, and particularly silk, it is almost impossible to prevent the silk from sloughing ofi from the end of the bobbin by reason of the sudden stopping of the shuttle in its travel.

It is a purpose of my present invention to provide means for resiliently supporting the bobbin so that the jars and vibrations incident to the sudden stopping of the shuttle will not be suflicient to remove the thread from the bobbin or the bobbin from the spindle, these means of support being so constructed that they will also effectively resist the force incident to such action. Such a device is shown in the accompanying drawings in which the numeral 5 indicates a shuttle case having a recess 6 within which a base 7 is rotatably mounted upon a I pivot. 8, said base. being held in predate positions by means at a spring 8,12.

ipindle 1O projecting from the end of the ase.

All of the parts thus fardescribed are of old and well known construction, and, except in connection with the parts to be hereinafter described, constitute no part of my present invention.

In carrying out my idea a spring is secured to the side of the base to provide a resilient support for a bobbin on the spindle, in one form of device this spring being attached by means of a clip 11 that is removably secured to one side of the base 7. A backturned part 12 from the clip provides space within which the end of the outer coil 13 of the spring is received and within which it is clamped and securely held by causing said back turned part to firmly bind theend of the spring in any suitable manner. This spring is preferably formed of flat metal of considerable width preferably disposed in conical form as shown in Fig. 1 of the drawings, it being noted that the spring is under full compression and that if relieved the side toward the base would assume a conical form as well as the opposite side. A sleeve 14 projects through the inner coil of this spring, a flange 15 on this end of the sleeve resting against the coils of the spring. This sleeve is provided with a swelled portion 16 to fit snugly within the quill 17 of the bobbin to hold the latter in place by frictional engagement, this sleeve and the quill being of well known construction.

The clip 11 is secured in place as by means of a screw 18 threaded into the base 7, said screw passing through a slot 19 in said clip. A tensioning lip 20 may be formed on the end of the clip to engage the edge of the base, or with tensioning shoulders constituted by grooves 21 in the side of the base, so that the clip may be placed in various positions, and the apex of the cone of the spring resting against the base, this change of the position of the clip will regu late the tension of the spring. A spring holding plate 22 may be secured in place by the screw 18, the end of this plate, when employed, resting against the edge of the spring and holding it from displacement withinthe backwardly turned part of the clip. The end of the spring may be enlarged as at 23, any suitable manner to prevent its withdrawal endwise of the spring train underneath said baakturned spect to the sleeve, I provide means for holding the latter. In one form of construction I produce this result by making the spindle of angular shape at its base, 2%, the square form being preferable, and by making the sleeve lat of corresponding shape to fit the spindle at this point as shown in Fig. 3 of the drawings, the sleeve will be held from turning movement with the quill when the latter is twisted to loosen it. This result may be attained in many different ways that will readily suggest themselves to those skilled in the art.

In Fig. 4 of the drawings there is shown a clip 26 that is formed integral with the spring as one means for securing the latter to the base 7, it being my purpose to use this form of clip with the device shown in Figs. 1 and 2 if desired.

lVhile I have shown and described herein a satisfactory construction of device embodying my invention, this may be departed from to a greater or lesser degree and yet be within the spirit and intent of the invention.

I claim 1. In a shuttle, a case, a base secured within the case, a spring composed of fiat metal arranged in a coil, means for securing one end of the spring to the base, a bobbin sleeve projecting through the center of said coil and having means to prevent its disengagement from said coil, and means for otherwise supporting the bobbin.
