P. COMEAU WEAVING SHUTTLE Filed RY 1924 Patented Nov. 3, 1925.

UNITED STATES PHILIPPE GOMEAU, OF NEW IBEDFO'RD, MASSACHUSETTS.

WEAVING- SHUTTLE.

Application filed May 6, 1924. Serial No. 711,478.

To all whom it 02mg concern:

Be it known that I, Pmnirrn OoMnAU, a

citizen of the United States of America, residing'at New Bedford, in the county of Bristol and State of Massachusetts, have invented a certain new and useful Improve ment in lVeaving Shuttles; and I do hereby declare that the following is a full, clear, concise, 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.

This invention relates to improvements in weaving shuttles, having for an object to provide a novel and efficient form of thread guide for shuttles, whereby the thread carried thereupon can be quickly and conveniently directed to the eye thereof and brought to a position with relation to said eye, whereat it may be passed or threaded through the same in a time much less than that required for threading operations with the now prevalent types or designs of shuttles.

It is likewise an object of the invention to provide a device of the character mentioned which, in addition to facilitating the threading of the shuttle eye, will provide an effectual tensioning means for the thread, causing the same to be evenly removed from the bobbin.

Other objects of the invention will be in part obvious, and in part pointed out here-' inafter. V

In order that the invention and its mode of operation may be readily understood by persons skilled in the art, I have in the accompanying illustrative drawings, and in the detailed following description based thereupon, set out one possible embodiment of the same.

In these drawing.

Figure 1 is a fragmentary side elevation of a shuttle equipped with the invention;

Figure 2 is an enlarged fragmentary perspective view of such a shuttle;

Figure 3 is an enlarged fragmentary detail in section taken on the line 3-3 of Figure 1;

Figure 4; is an enlarged fragmentary detail in section taken on the line 4 4E of Figure 1; and,

Figure 5 is a reduced top view of the same.

Having more particular reference to the drawings, in connection with which like characters of reference will designate corresponding parts throughout, 1 represents the shuttle proper having the usual pivotally mounted spindle 2 therein adapted to re ceive a bobbin such as indicated at 3, upon the same. One portion of the shuttle 1 is chambered or recessed as indicated at 4, such chambered portion 4: being disposed longitudinally of the shuttle proper 1 as is clearly shown in the Figures 2 and 5, the outer portion thereof being enlarged as indicated by the numeral 5, and having the lower portion thereof communicating with a longitudinally disposed reduced way (3. An eye 7 is received in an adjacent portion of the shuttle proper 1, transversely of the same, as indicated in the Figures 1 and 2 and is positioned adjacent to the inner end of said longitudinally disposed reduced way 6.

From the foregoing, it will be seen that a tortuous path of communication is established as between the spindle and bobbin receiving chamber or pocket of the shuttle 1 and the eye 7, whereby the thread 8 from said bobbin 3 may be passed into and through or threaded throughthe eye 7.

Vith a view towards providing effectual guide means for the thread 8 from the bobbin 3 in order that the same may be directed to a position adjacent to the eye 7 whereby to facilitate quick or convenient threading of the latter, I provide a guide indicated in its entirety by the numeral 9. a

This guide 9 consists of a single length of wire or similar pliable or bendable material, but which possesses sufilcient rigidity as to ensure its remaining in proper form subsequently to bending or shaping of the same.

The guide 9, as will be noted upon reference to the Figures 2 and 5, isv disposed longitudinally of the chamber 1, having its inner end bent at substantially right angles whereby to provide an anchoring arm or portion 10 adapted to be embedded in an adjacent portion of the bottom of the chamber 42. An arm 11 is bent diagonally clownwardly and rearwardly from the body portion of said guide 9 and as shown in the Figures 1 and 2, this arm is passed through a way 12 opening onto that side .of the shuttle proper 1 receiving the eye 7, whereupon it is extended in substantial parallelism to said side of the shuttle proper 1 and is outwardlybent and, substantially upon itself as indicated by the numeral 13. A

portion of this outwardly bent part of the arm 11, as shown in the Figures 1 and 2,

is extended across the eye 7, whereupon the free end of the arm is formed with a right angularly disposed anchoring finger l l engaged or embedded in an adjacent portion of the side of the shuttle proper 1.

In this connection, it *isto bei noted that the forwardly disposed portion of the out- 'wardly bent part 13 is directed through the way or opening 12 to a point whereat the same registers or aligns with the reduced longitudinal way 6, the purpose of which will be subseq'i'iently described.

In order that the eye '7 andthat portion of the arm 11 adjacent thesame will not interfere with free movement of the shuttle 1 during operation of the same,'I may and preferably do recess that side portion of said shuttle receiving the same in the man ner as indicated by the numeral 15, thus permitting the outer end or portion of the eye -7 and the outwardly bent portion 13 of the arm 11 to be inset with respect to the side of the shuttle 1 receiving the same.

The eye 7 is preferably made of porcelain as is indicated upon the drawings, having a thread receiving slot communicating at its lower end with the inner end of the reduced longitudinal way (5. This way (3 also lies horizontally of the bobbin as its outer end terminates at one side thereof and its inner end communicates with the bottom of the vertically and longitudinally extend ing recess 1. The medial portion of the wire 9 forms a loop shaped'guide finger lying longitudinally within the enlarged por tion 5 of the recess't whereby the thread will be directed from'the recess a into the way '6, but this wire does not extend into theway 6. Therefore, this wire 9 only forms a guide in so far as it permits the making of a loop in the thread andguiding the latter from the recess'et to the way- 6, but the particular-configuration of the walls of the recess& and the wayG, as shown, causes the thread to be finally threaded within the eye 7. V

The modus operandi of my improved shuttle is as follows:

To thread the eye 7, a portion of the thread 8 is removed from thebobbin 3 and I is passed along one side of the guide 9as is indicated in the Figure 2, whereupon and then drawn through the reduced longitudinal way 6 so that the same will be brought into the thread receiving groove or w'ay of the eye '7, it being borne in mind that the eye 7 communicates with the adjacent end of said way 6 and in consequence, permits the ready passing or threading of said thread through the eye 7. Dur ing this threading operation, it will be seen that the guide 9 will serve as an offectual means for carrying the span of thread 8 forwardly and then downwardly to a position adjacent the opening 12, whereupon, with passage of the freeportion of said thread throitigh the opening 12, it may be engaged and then drawn through the way 6 and threaded -with respect to the eye 7.

By usage of my improved threading device, an operator is permitted to effectually threadthe shuttle eye in a time much less than that required inthe threading operations of shuttles now prevalent in this art and furthermore, it will be understood that the effort expended during such a threading operation will be minimized.

Ma-nifestly, the construction shown is -capable of considerable modification, and

'of the shuttle having a constricted longitudinal way extending therefrom, a shuttle eye positioned in said side of the shuttle having its thread receiving recess communicating with said way,.and the thread guide finger formed of a single piece of material having one end thereof amrhored inthe guide chamberadjacent its point of communication with the bobbin chamber and disposed longitudinally of such guide chamber, the outer part of said finger being bent downwardlyand at angles upon itself and disposedin that portion, of the .same opening transversely onto said side of -the shuttle, the free end of the fingcr being disposedin substantial parallel relationship to an. adjacent portion of said side of: the shuttle and arranged in proximity to the constricted longitudinal way and said shuttle eye.

In witness whereof I have hereunto set myhand; I

PHILIPPE COMEAU.
