SHUTTLE.

Application filed. January 1a, 1918. Serial No. 212,510.

To all whom it may concern:

Be it known that I, JOHN Saii'rrr, a citizen of the United States, residing at Hopedale, in the county of WVorcester and State of Massachusetts, have invented an Improve ment in Shuttles, of which the following description, in connection with the accompany ing drawings, is a specification, like charac tors on the drawings representing like parts.

The invention to be hereinafter described relates to loom shuttles, and'more particu larly, though notnecessarily, to loom shuttles employed in filling replenishing looms.

Loom shuttles are ordinarily provided with a side delivery eye through which the yarn or filling is drawn from the carrier or bobbin as the shuttle is picked. As the shuttle enters the shuttle-box it is subjected to a binding action between the front and rear Walls of the shuttle-box to assist in arresting and properly holding theshuttle, and the shuttle is quickly brought to rest.

During the flight of the shuttle, however, the yarn or filling is rapidly drawn through the side delivery eye and,'as the shuttle is brought to rest at the end of its flight, the yarn or filling will frequently overrun and become slack between the shuttle and cloth selvage, notwithstanding the presence of tension means within the shuttle itself; Under such conditions the yarn or filling is liable to and frequently does fail to be properly presented to the filling thread cutter ordinarily used in filling replenishing looms, because, should the filling become slack between the cloth selvage and shuttle, it is liable to kink and take a wavy or irregular path between the shuttle and the cloth selvage where the filling thread cutter is .to act upon it.

An important feature of the presentinvention, therefore, consists of means on-the 1 exterior sidewall of the shuttle to engage the yarn of filling delivered from the yarn delivery eye as the shuttle enters the box and cause it to be pulled or straightened between the cloth selvage and shuttle; In carrying this feature of the inventioninto practical efiect, the means for thus engaging and positioning the yarn or filling is secured to the shuttle, and extends over the outer surface of the side wall thereof near the delivery eye, said means being provided Specification of Letters Patent.

with a surface adapted to retard free move ment of the yarn when engaged therewith. Another important feature of the inven:

tion consists in the yielding character of the yarn positioning means, whereby the yarn or filling may be pressed yieldingly against the side wallof theshuttle=box as the shuttle enters the box and drag upon the filling to straightenand position it with respect to the filling threadcutter. This characteristic of the invention may be-variously con trived, but in the present instance the yarn engagingmeans consists of some textile or other like material of yielding character mounted to extend transversely across the outer surface of the'side wall of the shut tle-box preferably near or adjacent to the side delivery eye.

The above and other features ofthe in vention will be hereinafter more fully described in connection with the accompanyf ing drawings showing one good, practical embodiment of the invention. v

Figure 1 is a perspective 'viewof a shuttle having the present invention associated Fig. 2 is a perspective view of the delivery eye end of the shuttle'with the yarn positioning device and its securing means shown in separated relation; and

Fig. 3 is a sectional perspective view transversely of the shuttle-box showingrthe action of the yarn positioning means upon the filling as the shuttle enters the box.

In the present illustration of the invention, the shut-tle 1, Fig. 1, may be of the usual type employed in filling replenishing looms. The filling carrier 2 having the filling 3 wound thereon maybe conveniently device which may be of anydesired or presupported in the shuttle 1 by the usual bob- I A At the end of the ferred character as well understood by those skilled in the art. In the present instance of the invention, the threadingdevice consists ofa threading block 5 having a thr'eading passage 6 whereby, after a filling has may be automatically threaded as the shutthe loom, all as common in the Mt.

.been replenished in the shuttle, the shuttle 1 The shuttle has a thread delivery eye 7 extending laterally with respect to the threading block 5 and through which the filling passes as the shuttle makes its excursions across the lay. The threading eye 7 maybe of usualcharacter common-in this type of shuttles.

In filling replenishing looms wherein prior to complete exhaustion of the filling in the shuttle a new, supply of filling is furnished, it iscommon to provide a thread" parter or cutter between the cloth selvage and the shuttle-box to part or sever the filling leading from the filling carrier or bobbin to be abandoned so that such filling end may be withdrawn with the outgoing filling carrier or bobbin and liability of its being interwoven with the cloth beavoided. Such thread parters or cutters are usually supported to perform their parting or cutting functions at a predetermined point in a line extending between the fell of the cloth or cloth selvage and the shuttle when the latter is in the box at the filling replenishing side of the loom. At such time-the delivery eye 7 is usually at the leading end of the shuttle. In other words, when the shuttle is in the box at the filling replenishing side of the loom, the yarn or filling leading from the side delivery eye of the shuttle extends substantially the full length of the shuttle between the side wall of the shuttle and the front wall of the shuttle-box,- and as the shuttle is brought to rest, the unwinding tendency, of the filling drawn from the filling carrier or bobbin in the shuttle is liable to cause the filling to become slack or kinked between the selvage of the cloth and the delivery eye of the shuttle so that it will not be in position tobe parted or caught by the thread parter or cutter.

The present invention, therefore, contemplates means for acting-upon the filling as it is delivered from the delivery eye of the shuttle to straighten the filling as the shuttle enters the box at the filling replenishing side of the loom and thus position the filling for the action of the thread parter or cutter. This is best effected b disposing on the outer side wall of the shuttle a yarn or fillingengaging device which will yieldingly press the filling against the side wall of the shuttle-box and obstruct free movement of the filling as the shuttle enters the box. I I I 7 In'the present instance of the invention, the side wall of the shuttle-is provided with a recess .8 back of the yarn delivery eye 7 in which isseated ;a support for thevyarnengaging and positioning means. In the presentinstance of the invention the support :comprises a plate 9, portions 10 of which are turned-or bentto provide journals for a stud or pin- 11 which extends transversely of the outer side wall of the.

Q11 may be rotatable, or. not, as desired. In

order that the yarn engaging and position ing means may yieldingly act upon the yarn 'orfilling as'the shuttle enters the shuttlebox at the filling replenishing side of the bloom, it is desirable thateithenthe cover ing 12 be formed of suliiciently yieldingimateria-l to yieldingly press the yarn against the inner wall of the shuttle-box as the shuttle enters the same, or, thatseparate yielding means be provided to hold the yarn yieldingly against the wall of the shuttlebox. In the present instance of the invention the supporter plate 9 is preferably formed of spring metal and is secured to the countersunk portion at Set the side wall by means of a screw or other suitable holding means 13 which is adapted tofpass through an opening 1st in the'sup'port or. plate 9 and into the-body of the shuttle.

It is usual in shuttles of the general char acter described to provide the side wall 15 of the shuttle with a longitudinal groove 16 through which the filling may extend when the shuttle is in the shuttle-box. The groove 16 is usuallyformedlongitudinally of'the shuttle in line with the side delivery eye 7.

The countersunk or recessed portion 8 formed in the side wall of, the'shuttle' is somewhat enlarged at 17, Fig. 2, to accommodate the yarn ei'igaging and positioning means, and is sufliciently deep to permit the yarn-engaging and positioning means to have a limited movement transversely rela'-' tive to the side wall 15 of the shuttle.

The construction above described as one embodiment of the present" invention is found to be efiicientand practical in 0bstructing the free move-mentof the yarn. or

filling by yieldingly pressing the same against the inner surface'of the sidewall '18 of the shuttle-box the shuttlefmov'es to the end. of its travel, the'construction being such that the yarn :or filling isstraightened between the cloth selvage and theshu't tle and properly positioned "for-the action of the threadparter or cutter.

The yarn-engaging and positioning means,

it will be noted, is in the natureof "a" pa'd' yieldingly supported upon the outer side wall of the shuttle back of the shuttle-eye, and acts upon the yarn orfilling to properly at the end of its flight.

cutter by pressing the filling yieldin'gly l against the wall of the shuttle-box" asthe shuttle moves to its final position ofrest,"

The lay 19 may, of course, be of any usual construction, and it, as well as the shuttle 1 may be provided with an opening for the passage of the filling carrier 2 when replenishment of filling is to be efiected.

What is claimed is:

1. A shuttle having a yarn delivery eye adjacent one end thereof, and a yarn positioning device on the exterior side wall of the shuttle back of the yarn delivery eye to engage the yarn between the side wall of the shuttle and the wall of the shuttle-box as the shuttle enters the box.
