SHUTTLE FEELER, FOR LOOMS.

Application filed October 12, 1925. Serial No. 61,970.

To all whom it nmy concern.

Be it known that l, Ham-1r A. DAVIS, a

citizen of the United States, and a resident of Hopedale, in the county of Worcester and State of Massachusetts, have invented an improvement in Shuttle Feelers for Looms, of which the following description, in connection withthe accompanying drawings, isa specification, like characters on the drawings representing like parts.

This invention relates to shuttle feelers for looms.

In looms of the filling replenishing type it is now the usual practice to provide a shuttle feeler which, on call for replenishment of filling, is moved to a rearward shuttle-feeling position to determine whether or not the shuttle has been fully boxed, and on failure to be so'fully boxed, to prevent operation of the filling replenishing mechanism. Should the shuttle not have been properly boxed, the metal end of the shuttle feeler will contact with the shuttle itself, and under such conditions is liable to Furthermore, should the filling be caught between the end of the shuttle feeler and the shuttle, it is liable to be broken or ruptured to such an extent as to cause filling failure on subsequent picks of the shuttle. It frequently happens that a shuttle maybe properly boxed; i. e., may enter the box fully and the shuttle feeler consequently move to its full rearward shuttle feeling position in front of the inner end of the boX, but under such conditions should the shuttle rebound it will engage the side ofthe shuttle feeler adjacent the shuttle box, and since theshuttle feeleris formed of metal, no injury is done.

One of the objects ofthe present invention is to provide a shuttle feeler with a shuttle engaging end formed of material which will not-injure the shuttle should the shuttle feeler enga 'e an improperly boxed shuttle. Owing to the character of the material forming the shuttle engaging end of the shuttle feeler, should the filling be clamped between the body of the shuttle and the end of the shuttle feeler, it' will not be broken or ruptured or crushed as heretofore, and consequently the loom may continue to run without broken filling.

As hereinbefore noted,a shuttle will sometimes rebound in the shuttle box after'the Shuttle feeler has moved to itsifull rearward .the bolt or stud 3.

position, and the present invention further provides a metal contactfor impact by the end of the shuttle in case of rebound. Such metal impact member is preferably formed as a cover plate overlying the side of the yielding material forming the end of the shuttle feeler, and is so related to the yielding end of the shuttlefeeler as not to engage the filling should the latter be clamped between the yielding material forming the end of the shuttle feeler and the shuttle bodyof an improperly boxed shuttle;

The invention and novel features thereof will best be made clear from the following description and the accompanying drawings of one good form thereof.

In the drawings:

Fig. l is perspective View of the parts upon a bracket 1 secured to the loom frame on which the shuttle feeler 2 is pivoted. as by If desired the shuttle feeler 2 may be mounted for pivotal movement in the guideway formed by the guiding members 4 and :5 supported from the loom Thelay 6 may be of usual construction and have mounted thereon the usual shuttle boX 7 for the reception. of the shuttle 8, in which the filling carrier 9 is mounted. The parts so far described may be of usual construction and be operated in the usual'mannerv to cause the 'feoler to move rearwardly into shuttle feeling position to determine whether or not the shuttle has been properly boxed. I

In accordance with the present invention, the shuttle engaging end of the shuttle feeler is formed of material, such, for instance, as fibroid, rubber or the like, which may engage the body of the shuttle should the latter not be properly boxed,.and'yet not injure the shuttle. In the present instance of the invention, the shuttle feeler 2 is provided with the fibroid shuttle engaging end which has the upper and lower jaws 11 and 12 constituting guiding means for the filling, and also impact members for engagement with the shuttle should it be not properly boxed. As shown more fully in Fig. 2, the rear end portion of the shuttle feeler is proYided with an opening or cut-away portion, as at 13, forming a tongue let to which is fitted the non-metallic end portion, 10 of the shuttle feeler. The particulars of detail in this connection, however, are not important, since such details may be varied within wide limits; but the construction described prorides shoulder portions 15 and 16 on the metal portion of the shuttle feeler against which the cooperatingshoulders of the nonmetallic end may rest.

overlying the material forming the end of the shuttle feeler is a cover plate 17 which may be secured in position by any appropriate means; one form of which, as indicated in Fig. 3, consists of pins 18 which may be utilized not only to secure the cover plate 17 in its overlying relation to the nonmetallic material 10, but likewise also-secure the yielding material 10 forming the end of the shuttle feeler in place. The pins 18, are preferably formed as rivets or pins having expanded ends flush with the surface of the cover plate 17 to offer no obstruction to the proper movement of the shuttle feeler into rearward feeling position.

The rear edge portions of the cover plate are in general conformation with the jaw portions of the non-metallic material 10 forming the end of the shuttle feeler, but the edges of the cover plate do not extend rearwardly as far as do the corresponding edges of the yielding material, with the result that not only does the cover plate not engage the shuttle should it be improperly boxed, but no injury is done the filling should it be caught between the improperly boxed shuttle and the end of the shuttle feeler. As shown, the edges 19, 20,, 521 and 22 of the cover plate correspond to the similar edges constituting the jaws of the nonmetallic material 10, but, as will be evident from Fig. 2, the edges 19, 20, 21 and 22 of the cover plate are not flush with the corresponding edges of the yielding material, and, consequently, do not engage either the shuttle or filling when the shuttle feeler ismoved to its rearward feeling position.

The metal cover plate 17 is primarily for the purpose of taking the impact of the end of the shuttle8 should the latter rebound in its box, av condition indicated in Fig. 3, where it will be noted that the end of the shuttle engages. the metal cover plate 17 which thereby protects the non-metallic material from injury by the end of, the shuttle.

It is common at the present time to proyidc the shuttle feclcr with a thread partcr or a thread partcr and clamp, and while such parts may or may not be employed in connection with the present invention, they are shown associated with the shuttle l't-clcr in Figs. 1 and 3. Since, however. the thread parter 23 and thread clamp 2t form no sential partof the present intention and may operate as usual, further description. of these elements will be unnecessary.

From the construct ion dc--ribe l as a good practical form (ii the pres invention, it will be apparentthat the end of the shuttle fecler is formed of material which may czn "e the shuttle without injui; thereto, or

, g'e the i'illing bet n itself and the slnule when the latter a improperly boxed without crashing or cell ing the Filling, since the yielding material itself presents a non-cuttingsnrface contact. The cover plate which OYClllQS the non-metallic material 10 at the side next to the shuttle box provides a metal contact for the end of the shuttle should the latter rebound in the box it being noted hat the edges of the non-metallic material 10 project rearwardly beyond the corresponding cdges of the cover plate. ll'hcn the shuttle feeler is in its rearward shuttle feeling position and the shuttle rebounds, the end of the shuttle will engagi c the plate 17 at a point opposite the backing portion lat formed in the metal of the shuttle feelcr itself and thereby further sustain the impact of the shuttle.

hat is claimed is:

1. A shuttle fecler having a tip of nonmetallic material formed with jaws to (fillbrace the body portion of an improperl boxed shuttle, and a metal cover protection plate secured to the shuttle feeler and overlying the side of the non-metallic tip next to the adjacent shuttle box to be engaged by the shuttle should it rebound.

2. A shuttle feeler having a tip of noninctallic material secured thereto. and a metal cover plate secured to the shuttle feelcr and overlying the non-metallic tip at'the side next to the adjacent shuttle box to receive the. impact of the shuttle should the latter rebound.

3. if. shnttle fccler having a fibrous shattle engaging end, and a cover plate secured to the shuttle feeler and overlying the fibrous end at the side adjacent the replenishing shuttle box, for engagement by a rebounding shuttle.

a. A shuttle feeler having a nou n'ietallic shuttle engaging end, and a metal cover plate secured to the shuttle fecler and overlying the side of the non-metallic end with the rear edge of the cover plate frontward of the corresponding rear edges of the nonmetallic end.

5. A shuttle feeler having a tip of nonmetallic material for non-injurious contact cover 5 with an improperly boxed shuttle and presenting a non-cutting surface contact with the filling should it be caught between the feeler and shuttle, and a metal cover plate secured to the shuttle feeler and overlying the tip of non-metallic material at the side next to the replenishing shuttle box.

'6. A shuttle feeler having a tip of fibrous material formed with shuttle engaging jaws, and a cover plate secured to the shuttle feeler and overlying the tip of fibrous ma terial on the side thereof next to the replenishing shuttle box. V

7. A shuttle feeler having a tip of nonmetallic material formed with shuttle engaging jaws, and a cover plate secured to non-metallic material on the side thereof next to the replenishing shuttle box, the rear edge of the tip of non-metallic material be- Li 8. A shuttle feeler movable to its rear- Ward shuttle feeling position on call for replenishing of filling and having a non-metallic shuttle engaging end formed with jaws, and a cover plate secured to the shuttle feeler and overlying the side of the non-metallic end next to the replenishing shuttle box to protect the non-metallic end from contact by a rebounding shuttle.

In testimony whereof, I have signed my name to this specification.
