SELF-THREADING SHUTTLE.

SPECIFICATION forming part. of Letters Patent No. 729,141, dated May 26, 1903. Application filed November 29, 1901- Serial No. 84,087. (No modeh To all whom it may concern:

Be it known that I, JEAN B. DAUDELIN, a citizen of the United States, residing at Fall River, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Self-Threading Shuttles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention consists in the novel features hereinafter described, reference being had to the accompanying drawings, which illustrate one form in which I have contemplated embodying my invention and a slight modification of the same, and said invention is fully disclosed in the following description and claims.

Referring to the said drawings,Figure 1 represents a top plan view of a shuttle embodying myinvention. Fig. 2 is an enlarged view of the threading end of the shuttle, showing the threading-plate removed. Fig. 3 is a side elevation of the threading end of the shuttle, showing the threading-plate in place. Fig. 4 is a section on line 5 5, Fig. 2. Fig. 4 is a detail of the adjustable tension device. Fig. 5 is a section on line 45 4, Fig. 2. Fig. 6 is a detail perspective view of the threadingplate and its securing-post detached. Fig. 7 is a detail perspective view of the deliveryeye and thread-retaining device. Fig. 8 is an end view of the same. Figs. 9, 10, and 11 are views similar to Figs. 1, 2, and 3, showing a shuttle provided with a slightly-modified form of my invention. Fig. 12 is a sectional view on line 13 13 of Fig. 10. Fig. 13 is a sectional view on line 12 12 of Fig. 10. Fig. 14 is a perspective view of the threading-plate. Figs. 15 and 16 are a perspective view and an end view, respectively, of the delivery-eye.

In the form of my invention shown in Figs. 1 to 8, inclusive, A represents the shuttlebody provided with the usual spindle-recess Ct, in which is located the spindle B. 0 represents the threading-recess, located in the shuttle-body forward of the spindle-recess and being preferably substantially circular in horizontal section. D represents a guiding-notch connecting the spindle-recess a with the threading-recess C and having an inclined shoulder d on the side opposite the delivery-eye to deflect the thread downward into said notch. E represents a metallic bushing or-liniug inserted in the delivery-eye on the shuttle. This bushing consists, preferably, of a piece of sheet metal bent into nearly cylindrical form, leaving a slit 6,

through which the thread may enter. Frepresents the vertically-disposed threading-slit extending from the upper face of the shuttlebody to and communicating with the slit e in the delivery-eye. At its outer end the bushing is provided with a thread-retaining device consisting of a vertically-disposed rod G, inserted in the shuttle-body in rear of the threading-slit F and extending across the end of the delivery-eye on the side adjacent to its slit 6, so as to prevent the thread from accidentally working out through slit e. The rod G may pass through a hole in the bottom of the bushing, as shown in Figs 7 and 8, or may pass outside of the end of the same, as shown in Figs. 15 and 16, the lower end extending into the shuttle-body. In either case a space is left between the upper edge of the bushing and the bar to permit the thread to pass from the opening in the bush to the other side of the bar, so thatthe rod G serves the double purpose of a thread-retaining device and a means for securing the bushing from working out of the shuttle-body. H represents the threading-plate, which covers the threading-recess and is supported on a horizontal shoulder f, formed on the shuttle-body in rear of the threading-slit F. The plate H is provided on the side opposite the deliveryeye with an upturned lip h, lying above the inclined face d, to catch the thread and defiect it down into the recess 0. The shuttlebody is cut away around the edges and beneath the plate H from the lip it around to the threading-slit F, as shown, so as to permit the thread to pass under the plate and enter the threading-slit. The plate H is held in position by the securing-post I, which has a head (preferably squared) passing through and countersunk into plate H, the lower end of the post I extending downwardly into the body of the shuttle below the threadingrecess and provided with an aperture 1', through which passes a horizontal retainingpin K, extending transversely through the shuttle-body. Within the threading-recess O is an adjustable tension device, which is pivotally mounted in the bottom of the recess and said plate H and. serves also to support the plate adjacent to its center. This tension device consists of a vertical post L, having cylindrical portions at its upper and lower ends to engage apertures in the plate H and the bottom of the threading-recess, respectively, the intermediate portions of said post being preferably square, buthaving its corners smoothed or rounded to prevent breaking or cutting the thread. From the bottom portion of said post L a curved arml extends upwardly and outwardly, the outer end of said arm being adapted to touch the curved wall of the threading-recess. The post L will be arranged concentric with the curved wall of the recess 0, so that said post and arm can be swung around to different positions without removing the arm Z from contact with the wall of therecess. By this means the thread may be caused to travel between the arm Z and post L and around post L at different angles, according to the adjustment of the post L, and the latter will be held in its adjusted position by the triotion of its cylindrical parts with the plate H and the bottom of the recess 0, said plate being held down firmly onto a shouldered portion of the post L, as shown, by the securingpost I. The curvature of arm lwill also serve to direct the thread when it enters beneath the plate H into the recess between said arml and the post L, as will be clearly seen in Fig. 5. The plate His also provided with a depending flange M adjacent to the threadingnotch'D, having an inclined edge N adjacent to but not parallel with the inclined shoulder d, said flange having at its bottom a recess m, formed between two projections mm. The operation of this form of my invention is as follows: The operator takes hold of the thread as it leaves the end of the spindle and with a quick forward movement, followed by a quick movement transversely of the shuttle, threads it. During the forward movement the thread is caught under the lip h of plate H and is then carried down between the inclined shoulderdand the inclined face Not the flange M and between the arm Z and post L of the tension device. During the transverse movement the thread is drawn around under the plate H to the threading-slit F, down said slit and into the delivery-eye, thus completing the threading movement, the operation being almost instantaneous. The tension device will be adjusted to give the required tension at the time of assembling the parts of the device. It is to be noted that there are no screws in the construction, which are objectionable, as they are apt to split the shuttlebody.

The form of my invention illustrated in Figs. 9 to 16, inclusive, is substantially identical with that previously described, except that the adjustable tension device is omitted, this form being cheaper in construction than that just described. In these figures, A represents the shuttle-body, a the spindle-recess, B the spindle, O the threading-recess, D the threading-notch provided with inclined shoulder d, E the delivery-eye provided with slit. e and retaining-rod G, and F the threading-slit, all constructed and operating substantially as hereinbefore described. In the threading-recess is placed a vertical post L, which serves as a tension device and is inserted in the bottom of the threading-recess C. The threading-plate is secured in position upon the supportingshoulderf by pins f f and is provided with an aperture 7L2 to receive the upper end of the post L. The plate H is also provided with a lip h, depending flange M, having the inclined guiding edge N, and the guiding-recess m between the depending points 17, n, as in the form previously described. The operation of the device in threading the shuttle is identical with that of the form previously described, except that there is no adjustable tension device, the thread merely passing around the post L, which exerts a certain frictional tension upon the thread.

What I claim, and desire to secure by Letters Patent, is
