HAND-THREADING SHUTTLE.

Application filed January 2, 1913.

Z70 all whom it may. concern Be it known that I, RICHARD PAOKER, a citizen of the United States, and a resident of Fall River, in the county of Bristol and State of Massachusetts, have invented an Improvement in Hand-Threading Shuttles, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to hand threading shuttles, primarily, the purpose thereof being to produce a shuttle that may be easily threaded by hand, and from the threading aperture of which the thread cannot be accidentally displaced.

In order that the principle of the invention may be readily understood, I have disclosed a single embodiment thereof in the accompanying drawings, wherein Figure 1 is a plan view of the forward portion of a loom shuttle embodying my invention, a portion thereof being shown in transverse section; Fig. 2 is a side elevation of the structure shown in F ig. 1; Fig. 3 is a shuttle upon the line 33 of Fig. 1; Fig. at is a front elevation of the threading member; Fig. 5 is a side elevation thereof, the member being slightly tilted; and Fig. .6 is a transverse section thereof on an enlarged scale.

The invention, in certain aspects thereof, may be applied to shuttles not of the hand threading type.

Referring to the drawing, the body of the shuttle is represented at 1, it being of any usual or suitable character, shape and material. Mounted therein in any suitable manner is a Weft carrier, here shown as a bobbin 2, which may be mounted on the usual spindle, not shown. Upon the bobbin is positioned the usual weft package 3. Axially in advance of the bobbin is the usual recess 4 which leads to the transverse socket 5, wherein the threading member is adapted to be positioned. The said transverse socket penetrates from the side surface of the shuttle transversely to a point of-intersection with the recess 4:. The shuttle body 1 is suitably slitted in order to permit the thread to be passed manually into and through the socket 5, thus avoiding the sucking of the thread through by the op- Specification of Letters Patent.

erative. For this purpose, I have repre.

sented an arcuate slot 6 cut or otherwise suitably formed in the top surface of the shuttle and a longitudinal slot 7 communi eating with the slotGin the usual or any desired manner. The arcuate slot 6 communicates at its inner end with the recess L at the front thereof preferably on the side the more remote from the side of the shuttle through which the thread 8 issues.

The parts thus far described may be of any suitable construction. lVithin the transverse socket 5 is positioned a threading member which, in this embodiment of the invention, is shown as a plate 9 preferably of soft steel. This plate is adapted to be secured within the socket 5 by a screw or other holding means penetrating thetop of the shuttle above said socket. To this end, thesaid plate may be provided with a suitable hole for the reception of thescrew or the plate may be fitted tightly into position in the socket and held there by friction,- but.

in such a manner as to permit it to be withdrawn when desired. The threading mem}.

constructed thatit imparts the desired fric tion to the thread in the weaving operation in both directions of throw of the shuttle. Furthermore the construction of said threading member is such that the thread is at all times positively held in proper, predetermined position, not only so that the shuttle cannot be unthreaded, but so that the thread is held in that position where the required tension is necessarily applied thereto.

The plate 9, as shown most clearly in Figs. 2 to G inclusive, is provided with a projecting prong 10 preferably integral therewith and reversely bent into general loop form, the end 11 thereof extending into close proximity to or into asooket or recess 12 formed in the plate. The prong lo'is preferably located close to or, at that side of the plate which is nearest the side 'wall 12 of the shuttle. Inasmuch as the plate is to vary the shape thereof orthe position of the extremity ll of the prong as ,desired.

Adjacentits opposite extremity the plate,

9 is provided with an'eye 13 which is axially inline with thefispinldle on which the bobbin 2 is mounted,so that the thread 8 is delivered aXiallv of the bobbin into said eye 13. To permit the proper threading of the shuttie, the eye 13 is provided with a flaring or other opening let, and if desired the upper surface of the plate may be slightly recessed in the rear of the eye 13 for the thread 8.

The thread receives friction as it passes along the upper surface of the plate to the eye 13. It will be observed that one wall of the opening let is bent upwardly. This insures the passage of the thread below that part of the plate which is between the eye 13 and the adjacent prong and guides the thread into its proper position with respect to the said prong. This purpose is readily accomplished by slightly twisting that portion of the metal which is between the opening 14 and the said prong.

Between the eye 13 and the looped prong 10, there is provided a second prong 15 preferably struck down from the body of the plate 9, as indicated most clearly in Fig. 1. This prong 15 is preferably curved rearwardly, as represented, so as to provide a slightly concaved, localized, guiding portion 16 for the thread. Inasmuch as the plate is made of soft steel, it is possible to bend the prong 15 so as to bring it in correct position with reference to the portion 17 of the prong 10 to impart the desired tension to the thread, and hence to vary the position of the prong 15, depending upon the character of thread and the amount of tension required thereby, it being the purpose of the construction to provide a somewhat circuitous route for'the thread about the two prongs 15, 10, so that friction is applied to the thread both by the prong 15 and by the prong 10. If desired, the prong 15 may be structurally distinct from the plate 9 and applied thereto in an adjustable manner, so as to permit it to be positively adjusted in and out with respect to the front prong 10, thereby to secure the proper friction, and to vary the friction with the character of the thread. It Will be observed that in the construction shown the prong 15 is substantially in transverse alinement with the portion 17 of the prong 10, thus compelling the thread to take a circuitous route to the front of the prong 15 and to the rear of the part 17 of the pron 10. v

The thread 8 is drawn into the arcuate slot 6 down into the slot 7 and is then drawn past the extremity 11 of the prong 10 or to the left thereof viewing Figs. 2 and 6. The relation of the extremity 11 of the prong 10 to the socket or recess 12 is such that the thread is in the threading operation passed up into the socket or recess 12 about the point 11 and thence down into the looped portion of the prong 10. The construction is such that it is impossible to reverse the operation and dethread the shuttle by passing the thread up past the point 11 into the recess 12, and thence to the right, viewing Fig. 6.

When the shuttle is moving toward the right, viewing Figs. 1 and 2, the thread receives friction against the front face of the prong 15 and also against the inner face of the member 17 of the prong 10, thus imparting the desired friction, and when the shuttle is moving in the opposite direction or to the left viewing Figs. 1 and 2, the thread receives friction against the outer face of the prong 15 and against the opposite member of the prong 10.

It will be observed that the curved formation of the prong 15 and of the member 1? of the prong 10 are such that the thread is fixedly held from vertical movement along these prongs and hence cannot be moved upwardly toward the end 11 of the looped prong 10. The spacing apart of the prongs 10 and 15 is important, for if they were continuous there would be but little friction imparted to the thread which would slide freely along them, but by providing the separated rongs or projections as described, there is suflicient friction imparted to pre vent the too free playing off of the thread from the shuttle.

Obviously the entire structure can be stamped from a single piece of metal and bent into shape at a single operation and at exceedingly slight cost.

The construction is such as absolutely to prevent the dethreading of the shuttle, while at the same time sufficient friction is imparted to the thread whatever the direction of motion of the shuttle.
