4 To all whom it may concern Be it known that I, PASQUINO FERBAR a subject of the King of Italy, residing at Fall River, in the county of Bristol and State of Massachusetts, have invented cer tain new and useful Improvements in Loom-Shuttles, of which the following is a specification.

The invention relates to loom or weavers shuttles being intended chiefly for shuttles containing aboldbin upon which a thread of wool is wound, the purpose being to preserve a proper tension upon such'thread, whereby it is caused to feed uniformly, thereby resulting in the formation of a smooth cloth which is free from knots or uneven places.

A further purpose of the invention is the provision of a thread tensioning device embodying a plurality of eyes and thread en-' gaging elements, said device being of peculiar form to admit of the quick threading thereof without requiring the use of a hook or the resorting to suction for drawing the thread through the eyes.

The invention also has for its object to provide a device which may be readily applied to any make of loom shuttle and which when in position may be positivelysecured so as, to prevent casual displacement or movement of the device which would impair its efiiciency.

With these and other objects in view, which will readily appear as thenature of the invention is better understood, the same consists in the-improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly claimed. I

In the accompanying drawings has been illustrated a simpleand preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the invention as claimed may be resorted to when desired.

" Referring to the drawings, 'Flgure l is-a perspective view of an end portion of a loom shuttle provided with a thread tens 1oning device embodying the invention. F 1g. 2

videdwith the bobbin recess 2, and threadmg recess 3. The usual thread, groove 4, extends along one-sideof theshuttlebodyq and communicates at its front end with the,

eye 5- through which thegitliread Y6 passes.

The eye ,5 constitutes the'deliveryendof a thread passage comprising a vertical portion 7 and a laterally inclinedportion 8.

i The vertical portion 7 of the thread passage extends through the bottom of the threading recess 3. The portion 8; of the thread passage extends transversely and'obliquely, as

illustrated most clearly.in';Fig. ,2.' A tensioning element 9 islocated upon the bottom of the threading recess?) and consists of a piece of felt, textile or like material which; will offer' a resistance toithe thread thereo'ver when under tension.

I j I as used in looms for weaving and is prop passage of the The tensioning device is disposed upon the side of the shuttle provided with the thread groove 4 and is fitted within a suit- A tensioning device is preferably constructed of metal, although any suitable material may be'employed, and such devicelnay be able recess formed in the side portion ofthe l to interfere with the operation of the shuttle. r

castor constructed in any manner found T most advantageous. In its general forma} tion the device comprises a face portion and.

a back, the face portion embodying oppositely inclined wings. "Eyes 10 and 11 are" line from which-the wingsromprising the face portion of the device" incline. Slits 12 and 13 extend from the eyes 10 and 11 in] opposite directions and constitute passages for the thread whenthreadingthe shuttle; The upper wing of'the device comprises a" tongue 14 and a partl5, the tongue 14 projecting and terminatingin a spur 16 which formed in the device in position'to aline with f the thread groove 4' a'nd'with the median is adapted 'to be driven into theshuttle asto assist materially in holding the device" in place. The upper edge of the part 15 ii -fl" 30 lower .end of the tapered projection 24 apclines toward'the slit'13, thereby forming a protuberant portion'17 which is adapted to readily'engage the'thread when placing the same in position. The upper po "tion 15 is spaced from the shuttle a short istance to provide a passage for the thread. The

tongue 14 fits close against the sl uttle. The lower wing of the face portion lof the tensioning device comprises a bea 18 and a part 19. The lower edge of the part 19 inclines toward the slit 12 so as to direct the thread into the slit 12. The inclined edges of the parts 15 and 19 constitute directing edges to guide the threadinto the respective slits or passages 13 and 12. The part 19 fits close against the shuttle whereas the beak .18 is spaced from the shuttle a short distance to admit of the thread passing in the rear thereof. Projections 20 are formed upon the rear. side of the device and are spaced. ,apart longitudinally. These projections 20 have openings 21 formed vertically therein 125 from the face portion ofthe device connects to receive pins or fastenings 22 by means of which the devlce is made secure when placed 111 posltlon. A web 23 extending rearward the lower ends of the projections 20. A tashuttle adjacent the threading recess 3 pered projection 24 is formed upon therear of the part15 of the upper wing and is disposed between the projections 20. The

within the side recess formed in the shuttle As indi to receive the tensioning device. cated most clearly in Fig. 2 the wall of the 1s thickened and such thickened portion is recessed in its outer side to receive the tensioning device, the latter being retained in place by means of the pins 22 and the spur 16.

A shuttle provided with a tensioningde? vice embodying the invention when properly. thmaded has the thread passing in front of the tongue 14 thence through the eye 11 back of the part 15 around the longitudi I nally curved portion 25 of the projection 24:

through the eye of the shuttle in any well and beneath theoverhanging portion ofsuch projection, thence out through the eye 10 and over the end in front of the beak 18, as indicated most clearly in Fig. 2. The thread is deflected around'the rearwardly curved portion 25 of the part 24 and is thereby subjected to tension. The thread 6 is passed known manner and is passed in front of the tongue lei and in the rear of the part 15 and i the eye 10 thence in front of the beak 18.

The taper of the projection 21 is such as to insure the ready passage of the thread thereover when drawn downward and when the thread reaches the reduced part 25 is retained in placeby the overhanging portion of the part 21 and more particularly bythe undercut edge of such overhanging part.

A piece of felt 26 is located opposite the tongue 14 and at the juncture of the recess receiving the tensioning device and the thread groove 1. This piece of felt 26 serves to keep the thread clean and to remove any beards or projecting parts. \Vhile it is preferred to use felt in providing the part 26 it is to be understood that textile or other like material may be advantageously employed. It will be understood from the foregoing taken in connection with the accompanying drawing that the invention provides in effect a plurality of threading eyes for a loom or weavers shuttle since in addition to the usual eye 5 the device provides other eyes 10 and 11. These supplemental eyes 10 and 11 are adapted to be quickly threaded, it being necessaryonly to pass the thread back of the part 15 and up in front of the beak 18,

such movement causing the thread. to passthrough the passages 13 and 12 into the eyes 11 and 10. It is also noted that the recess 27 provided for receiving the tensioning device is of such shape as to accommodate the various parts of the device and yet prevent any portion of the device projecting so as to.

interfere with the movements of the shuttle when in operation.
