Application June 25, 1947, Serial No. 756,830

11 Claims.

This invention relates to improvements in :shuttles for fabric weaving looms and more particularly to novel means of securing protective tips to the ends of such shuttles.

One of the principal objects of the invention is 'to provide novel means of securing o-r anchoring metallic tips to the ends of shuttles of the conventional type used with looms for weaving fabrics to more permanently hold said tips.

Another object is to provide improved means of securing metallic tips to the ends of shuttles of the conventional type whereby the force or 'blow imparted to said ends by the picker stick during the weaving operation tends to increase the anchoring effect rather than causing loosening of the metallic tips.

Another object is to provide novel means of preventing checking or cracking of the ends of the shuttle to which the metallic tips are con- .nected.

Another object .is to provide sleeve type connection means, for securing and anchoring Inc-- xtallic tips to the shuttles, so constructed .as to prevent loosening of the tips during use and to aid in preventing the ends of the shuttles from checking and cracking.

Another object is to provide anchoring or securing means for the metal ends of shuttles which will aid in preventing said ends from twisting relative to their initial set position of asdrawings and it will be apparent that many changes may be made in the details of construction, and arrangement of parts shown and 'described without departing from the spirit of the invention as expressed in the accompanying claims. We, therefore, do not wish to be limited to the exact details of construction and arrangement of parts shown and described as the preferred forms only have been given by way of illustration.

Ithas been a conventional practice for a number of years to provide shuttles, of the type employed with machines such as looms for weaving fabrics, with metallic tips for prolonging the life and durability of such shuttles.

One of the major problems, in the past, has.

been in securing and anchoring the tips in position whereby, during the weaving operation, said tips will not become loosened and displaced or the ends of the shuttle become checked or cracked thereby rendering the shuttles impractical for further use. In several instances in the past, particularly when the metallic tips become loose, great damage has been caused to the warp on the loom. This damage, in most instances, was due to the shuttles being deflected, due to loose tips, from their normal path of travel transversely of the lay of the loom with the result that said shuttle will be directed through the warp and cause the ends to break and to cause considerable time to repair the damage done and also introduced the further element of danger of possible injury to the operator as well as other operating mechanisms of the loom.

One of the prime objects, therefore, of applicants invention is to overcome the above difficulties through the provision of novel means of anchoring the metallic tips to the ends of the shuttles whereby the said anchoring and retaining of the tips in position tends to increase its holding function during use and further tends to obviate the tendency of the ends of the shuttles to check and crack.

Referring to the drawings:

Fig. VIII is a sectional view of a further modifled form of connecting means.

Referring to the drawings wherein like charactors of reference designate like parts throughout the several views, the shuttle embodying the invention, as shown in Fig. I, comprises a main body portion 9 having opposed tapered ends l0 and an intermediate slot ll extending longitudinally thereof.

Inwardly and adjacent one end of the longitudinal slot H, there is provided a conventional type clamp l2 for engaging the head [3 of the bobbin [4 for retaining said bobbin in said slot. The end of the filling [5 carried by the bobbin I4 is threaded through the conventional threading means H; of the bobbin in the end thereof opposed to the clamp means l2.

The tapered end portions iii of the shuttle, as shown best in Figs. II and III, are provided with metallic tips I! of a shape which will blend with the outer surfaces of said end portions H].

The main body portion of the shuttle is formed of a fine-grained wood such as dogwood or persimmon or may be formed partially of plastic or combined wood and plastic or other suitable materials known in the art.

The arrangement embodying the present invention comprises a metallic tip I! and a tip locking device 2| adapted to be fitted within the tapered end portion [0 of the shuttle. The tip portion l1 comprising a shank i8 is formed with a knurled portion l9 adjacent the base of the tip. The base of the tip I! is preferably provided with an annular recess surrounding the knurled portion l9 and having its outer contour spaced inwardly from the adjacent contour edge of the base. The tip locking device comprses a pair of concentric sleeve portions 22 and 23 held in fixed spaced relation with each other by an end web or wall 24. The sleeve portion 23 is provided with an inwardly tapering end 25 and sleeve portion 22 is provided with an outwardly tapering end 26, see Fig. II.

The end portion [0 is preferably provided with a substantially fiat surface 21 having an annular or circular recess 28 therein adapted to receive the sleeve portion 22. Centrally of the recess 28, there is provided a counterbore 29 for receiving the sleeve portion 23 and a slight counterbore 30 for receiving the webbed end 24. Centrally of the counterbore 29, there is a longitudinal opening 3| adapted to receive the shank I8.

In forming the tip locking device 2 I, the diameter of the sleeves 22 and 23 as well as the thickners of the walls of said sleeves are carefully controlled as to dimension. The space 32 between the said sleeves is also controlled so that the said parts of said tip locking device will be substantially of uniform size and relation with each other. The diameter of the bore 33 of the inner sleeve 23 is also controlled so as to be of a given amount le?s than the dimension of the shank portion l8. The outer wall 34 of the recess 28 is preferably of a diameter slightly larger than the outer diameter of the sleeve portion 22 while the inner wall 35 of the recess 28 is of a diameter slightly greater than the diameter of the inner wall 36 of the sleeve portion 22. The depth of the recess 28 is approximately only two-thirds of the length of the sleeve portion 22 whereby, when the said sleeve portion 22 is driven inwardly of the recess 28, the outwardly bevelled end 26 of said sleeve portion will cause the said end to expand inwardly of the solid wood as shown at 3'! in Fig. III thereby locking said sleeve inwardly of said tapered end [9. It is to be noted that a slight space 38 remains between the outer wall of the recess and the outer adjacent surface of the sleeve portion 22. This tends to prevent the checking and cracking of the end. While the outer sleeve portion is formed in the above manper, the inner sleeve portion 23 has an outer diameter which is slightly larger than the diameter of the counterbore 29 with the result that the space 32 between said outer and inner sleeve portions 22 and 23 is considerably less than the thickness of the walls of the annular portion 39 lying between the counterbore 29 and the recess 28. The length of the sleeve portion 23 is greater than the depth of the counterbore 29 whereby the end of the sleeve portion 23 will be forced downwardly into the solid side walls of the drilled opening 3| when being driven or pressed within the end of the portion In. The tapered end 25 functioning cooperatively with the oppositely tapered end 26 will tend to cause the material of the portion l 0 to be squeezed or crowded inwardly between the sleeve portions 22 and 23 thereby introducing a firm binding action with the tendency to increase its above function when force is exerted on the end wall 24 of the locking device. After the tip locking device is seated into the end portion !0, as illustrated in Fig. III, the shank 28 together with the knurled portion [9 is then driven or pressed into seated relation with the end 21. The base of the tip I! is preferably formed slightly concave, as shown at 40 in Fig. III whereby the outer edge thereof will tend to cause the material at the end surface 21 to be crowded slightly inwardly of said cupped surface 40.

The shank, being of a larger diameter than the drill hole 3!, will be firmly locked in place and the knurled portion 19 which is of a diameter greater than the diameter of the bore 33 of the inner sleeve portion 23 will cut into the metal and will interlock therewith and thereby prevent rotation of the tip I! relative to the adjacent end ID of the shuttle. The tip locking device may be formed of brass, copper, bronze, or steel or any other suitable metal.

It is quite obvious that due to the fact that the space 32 between the outer and inner sleeve portions 22 and 23 is less than the width of the wall 39, that is, when the tip locking device is forced or pressed within the recess 28, there will be an increased tendency for the bevelled edges 25 and 26 to direct all the material of said wall 39 inwardly of the space 32 thereby causing a compression of the material of the portion 39 and a friction binding of the locking device therewith. Simultaneously, to this function, the bevelled end 25 being forced into the solid material of the end portion it will cause the adjacent end of the sleeve 22 to spread outwardly, as shown in Fig. III and thereby firmly anchor the locking device within said end l0. When the shank l8 and knurled portion i9 are forced inwardly of the bore 33 and drilled opening 3| to a position wherein the base of the tip I! is seated against the end surface 27, there will be a further expanding action introduced on the inner sleeve 23 during the cutting of the knurled portion i9 inwardly of the adjacent material of said sleeve thereby further tending to anchor the parts in place. Force applied to tips H during use will tend to more firmly anchor the parts in place rather than to cause them to loosen. Due to the fact that the outer wall 34 of the recess 28 is of a diameter larger than the outer diameter of the sleeve portion 22 and that a slight space 33 remains about the assembled parts, the danger of having the end check or crack is greatly reduced. A more positive mechanical bond or anchoring of the tip inwardly of the end It is therefore introduced and a much more permanent connection is obtained.

Referring to Fig. VI, there 'isshown'a slight modification of a tip locking device which. is generally'similar to the tip locking device such as illustrated in Figs. II and III except that it has an integral flange portion M extending outwardly of the end wall 32 which supports the inner and outer tubular portions 33 and 54 in desired spaced relation. The device shown in Fig. VI functions in a manner generally similar to that shown in Figs. II and III with the exception that the flange il is adapted to overlie the end surfaced! between said end surface and the base of the tip I! when in use.

In Fig. VII, there is shown a further modification of the invention wherein the central opening, simulating the opening 3|, extends entirely through the adjacent end portion of the shuttle. In this instance, the central opening 48 communicates with the longitudinal slot II and is increased in diameter inwardly of said end portion by an amount sufiicientto permit a cap member i! to be pressed over the inner end of the shank $8 of the tip 49, which shank 48 and tip ell are generally similar to the shank l8 and tip ll shown in Figs. II and III. The connection means is otherwise generally similar to that shown in Figs. II and III with the exception that the side walls of the cap portion ll are of such diameter as to frictionally interlock with the shank portion 48, that is, the central bore of the cap portion 41 is of a diameter less than the diameter of the shank 48 whereby the parts will frictionally interlock with each other. I

In Fig. VII-I, there is illustrated a further modification wherein the inner sleeve portion which simulatesthe inner sieeve 23 is formed to a length considerably greater than the length of the outer sleeve portion '51 It is to be understood that in a tip locking device such as shown in Fig. VIII, the counterbore, such as shown at 29, will be formed of a depth su'fiicient to accommodate for the'inner sleeve portion 56. Each of the'tip looking devices shown in Figs. VI and VIII maybe used as repair units with shuttles from which the tip portion I! has been loosened. understood, of course, that the end ID of the shuttle would have to be initially prepared in a manner generally similar to that illustrated in Fig. II to receive the tip ll as well as the integral shank l8 and knurled portion l9 and also the tip locking device.

It is particularly pointed out that the inner sleeve portion 23, as shown in Figs. II and III, is initially formed to a length slightly less than the length of the outer sleeve portion 22 thereby enabling a greater amount of the material of the end portion 10 to be forced inwardly between said inner and outer sleeve portions 22 and 23. The inner surface 52 of the web 24 is adapted to engage the end surface of the annular wall portion 39 and thereby aidin resisting any shock or force inwardly directed against the ti I'i'. From the foregoing description, it will be seen that simple, efficient and economical means have been provided for accomplishing all of the objects and advantages of the invention.
