filECmGATION forming part of Letters Patent No. 748,922, dated January 5, 1904.

Application filed May 11, 1903.

To all whom it may concern: I

Be it known that we, OAMILLE BRUN and GUsTAvE BRUN, citizens of the French Republic, residing at Lyons, Rhdne, France, have jointly invented certain new and useful Improvements in Shuttles, of which the following is a specification.

This invention aims to provide an improved loom-shuttle of the same general character as that described in the application for patent of Brun and Brun, Serial No. 153,435, filed April 20, 1903. It is specially designed for operating or controlling mechanism for stopping the loom or for supplying new weft or for similar purposes. Looms having mechanism of this kind are well known. An example of such a loom is shown in the patent of Brun, Brun, and Bicking, No. 714,655, granted December 2, 1902. The specific improvements shown in this application are specially designed for operation with the loom mechanism of said patent, though the invention contemplates, broadly, a shuttle adapted for use with various other loom mechanisms. For this purpose the invention provides means in the shuttle for controlling mechanism of the loom and a part of which is adapted to be surrounded by the thread on the spindle and at least the end of said part being substantially within the surface of the spindle when the mechanism -controlling means are inoperative. The position of the end of the part of the device surrounded by the thread facilitates the application of the thread on the spindle without catching under the end of said part.

We have shown in connection with the shuttle mechanism described a quill of special design and material and have shown the spindle of the shuttle of a form particularly adapted for use with said quill, as hereinafter described.

Various other features of improvement are specified in detail hereinafter.

The accompanying drawings illustratean embodiment of the invention.

hausted. Fig. 3is a horizontal section of the same through the center of the spindle. Fig. 4 is a horizontal section of the same with the spindle turned up, the plane of section through the spindle being taken on the line 4 def Fig. 3. Fig. 5 is a longitudinal section of the shuttle, showing the spindle in side elevation. Fig. 6 is a similar section through the center of the spindle. Fig. 7 is a section similar to Fig. 6, but with the spindle raised to the position in which the quill is applied. Fig. 8 is a side elevation of the spindle in the position of Fig. 7 and with the quill applied thereto. Fig. 9 is a cross-section on the line 9 9 of Fig. 8.

Referring to the embodiment of the invention illustrated, the spindle A is pivoted at its heel about a hollow shaft B and is held impositively in its raised or lowered position by means of the usual spring C or any other suitable means. The means for controlling the mechanism of the loom comprises a member illustrated in the form of a pin D, transversely movable and provided with an arm E, the outer portion of which is adapted to be surrounded by the thread on the spindle in the manner explained. The end F of the arm E is preferably tapered, so that the portion of it which is first met by the quill or the thread as the latter is introduced onto the spindle (the arm being moved up against the spindle, as hereinafter explained) is substantially within or flush with the surface of the spindle, which permits the thread and the quill to pass over the end of the arm and to surround a considerable portion thereof, as shown in Fig. 3. Preferably a groove G is formed in the side of the spindle, arranged to register with the end of the arm E when the latter is moved inward, so that the latter may enter the groove and be absolutely within the surface of the spindle. With the parts in this position the arm E, and with it the pin D, are held inward in the inoperative position of the latter against the pressure of the spring H. When the thread is exhausted or so nearly exhausted that its resistance is not sufficient to hold the spring H compressed,the spring moves the pin D outward, and thus determines the operation of the stopping or weft-replenishing mechanism of the loom.

Preferably the pin D is automatically moved inward as the spindle is turned up to the position for supplying a new lead of thread. This may be accomplished by the use of a wire cam J, lying in the path of the arm E, the latter being moved up and down with the spindle by means of pins K, projecting from the heel of the spindle and engaging the arm E on opposite sides. This mechanism is claimed in the application of Brun and Brun above referred to.

The shuttle is shown in connection with a thin-walled quill or cop-tube L, of paper or the like, and the longitudinal opening M provided in such quill for registering with the arm E is preferably in the form of a mere slit. The slit M, it will be understood, is to enable the arm E to escape as soon as the thread is so nearly exhausted that it has not sufficient strength to hold the walls of the opening together and to thus hold the arm E in against the spindle in opposition to the action of the spring H, or the openingM may be of appreciable width, so that the thread bears directly on the arm E to hold it in against the spindle. The mechanism described is of special use in connection with such a quill, since it enables the workman to apply this cheap quill to the shuttle quickly and without any special care.

The apparatus may be specially adapted for slitted quills of the kind described or of any other suitable kind by the provision of mechanism (illustrated best in Figs. 5 to 7, inclusive) for spreading the sides of the slit or other longitudinal opening provided. The mechanism shown permits of the application of the quill with the spindle in the upright position, as usual, and upon the turning of the spindle down to the running position automatically brings into action a spring-pressure tending to spread the sides of the opening, so that the arm E or other part of the mechanism controlling means is substantially free except for its control by the thread. For this purpose the spindle shown is provided with a vertical longitudinal slit in which is an arm N, pivoted at O and adapted at its forward end to swing down to the position shown in Fig. 7, with the lower portion P thereof projecting out of the spindle, or to the position shown in Fig. 6, with its upper edge projecting above the spindle.-

The portion P is oifset, as shown, and lies entirely beyond the lower end of the quill. The parts being in the position of Fig. 7, the quill may be introduced without difficulty, fitting exactly the spindle. As the spindle is turned down, however, the projection P engages a spring-stop consisting of a wire Q extending across the lower part of the shuttle, which engagement tends to throw the end of the arm N upward until the upper edge of the arm projects above the surface of the spindle and to thus spread the slit or other longitudinal opening in the side of the quill. When the quill is first inserted with the arm N withdrawn, it appears as in Fig. 8. When the arm N is pressed upward, the slit in the quill is enlarged, as in Fig. 5. The stop Q may be a transverse wire forming the end of a longitudinal wire R, entering the side of-the shuttle at its opposite end and resting at an intermediate point on a pin S, so as to permit a certain amount of yield ing of the stop Q proportioned to the resistance of the quill and the thread surrounding it. The end of the arm N may be forked and limited in its movement by a stop comprising a pin T,extending transversely across the slot in the spindle. The turning upward of the arm Nprovides, as will appear from Fig. 6, an extra enlargement of the base portion of the spindle beyond that which would bedue to its taper form, and obviously a permanent enlargement of this kind might be used for the same purpose, though it would make somewhat more difficult the insertion of the quill 0n the spindle.

The invention provides also means for holding the quill on the spindle. These means are especially useful in connection with the A tapered spindle shown and with the extra enlargement at the base thereof for spreading the longitudinal opening of the quill. The means illustrated are especially adapted for the paper quill described. They comprise in the form illustrated an arm U on the same pivot O and moved with and preferably formed integral with the arm N and provided on its under side with one or more teeth adapted to bite into the material of the quill, and thus hold it from withdrawal. This arm U is pressed down to the engaging position and its teeth are pressed into the smooth inner surface of the quill as the spindle is turned down and as the projection P engages the stop Q and throws up the arm N in the manner described. This effectively prevents any movement of the quill toward the end of the spindle after it has once been applied.

The functions and modes of operation of the several individual features of the invention being clear, only a brief description of the operation of the complete shuttle and mechanism shown will be necessary. The spindle is first turned up to the position of Fig. 7, the cam J at the same time forcing the arm E to its inward position as the arm is carried up by means of the pins K. The transversely-moving pin D at the same timeis moved to its inward position, Fig. 3. The quill, loaded with thread, is then applied and surrounds the end of the arm E, so that as the spindle is turned down the arm E and pin D are held in, with the latter in its inoperative position. As the spindle is turned down the projection P in the quill-spreading device engages the springstop Q and presses the upper edge of the arm N, so that as the thread runs off the latter gradually moves out beyond the surface of the spindle, spreading the slit M in the quill, as shown in Fig. 5. Thearm E is then free from any control by the quill and is held only by the remaining thread. Simultaneously with the upward movement of the arm N the arm U is pressed downward, so that its teeth bite into the quill, as shown in Fig. 6, and prevent longitudinal movement of the latter. When the shuttle has run until the thread is nearly or substantially exhausted,the strength of the spring H overcomes the resistance of the thread and forces out the arm E and the pin D, the latter operating the loom mechanism, as described.

We make no claim in this application to the quill of special design and material described or to the special construction of the spindle for spreading such a quill or for biting into and retaining it on the spindle, these features being claimed in our application, Serial No. 167,730, filed July 31, 1903.
