' 4 claims. (C1. 139-198) l ...This invention relates to what are known in the textile industry as carpet or open top, hand threading shuttles as distinguished from automatic threading shuttles by the fact that the yarn package used in such shuttles unwinds from the inside instead of from .the outside of a cop or bobbin and is held in place in a recess or cop cayity in the shuttle which; has side walls the inside faces of` which are usually serrated, and a bottom but an open top.

, There is usually an outlet eye orthread eye atwhat we will call the front end of such a shuttle which passes through a side wall into the recess.

, In the past, it has been considered necessary to have'a cover which may or may not be more or less resilient, pivoted at the back end of the recess or the end away fromlthe frontor the shuttle eye end,rand of such a character that its free end is bent to form a hook to engage a latch device member which is movable and may be of various characters such as shown in the patents to: Shand, No. 339,941 of April 13, 1886; Sergeson, No. 1,278,034 of September 3, 1918; Richardson, No. 1,510,861 of October 7, 1924; Sergeson, No. 1,728,083 "of September 10, 1929; andSergeson, No. 2,071,238 of February 16,1937.

' `We have discovered that byusing a flat resilient cover of substantially the same width throughout its'length and with `a free end, which is preferably rounded, to go under a holding pin extending across the recess at the front end and having at the back end of the recess a pivot part of substantially cylindrical form in which is a tightly fitting resilient lining throughwhich a pivot pin is driven, such a device will hold the yarn mass resiliently in place and can alsdbe easily released from or engaged with the holding pin 'at the front end. The combinationvof the resiliency of the yarn mass, the cover itself and the elastic lining, will allow the shuttle to operate in the loom without noise and without vibration, the whole construction being much simpler than any now in use.

Our resilient construction of the cover which rests upon the substantially resilient yarn package combined with our resilient lining, all cooperate to take up the shock which a shuttle is constantly receiving from the picker action. rAltogether they absorb this shock so as to prevent or greatly reduce the tendency, which is found in shuttles of a similar type and for a similar 2 breaks not only do damage to or destroy the usefulness of the shuttle itself but also cause enormous damage to the warp when and if the broken parts of the cover project.

The elimination of numerous pivot parts, arms and so forth, greatly simplies the construction, reduces the crystallizing points and serves the desired purposes in a much better manner.

In the drawings, Fig. 1 is a top plan view oi a shuttle with a yarn or thread package resiliently held in place by our device.

Fig. 2 is an elevational View as from the eye side or bottom side of Fig. 1 with parts broken away and with the cover member shown in dotted lines as bent to release or lock its free end but without a thread package.

Fig. 3 is a broken side elevational View of a shuttle as from the pivot. end of the cover with a package held in running position.

Fig. 4 is a lateral vertical sectional View as on the line 4--4 of Fig. 3.

The metal pivot pin H is driven through a closely tting hole in the wood and in the lining F so that the cover moves very slowly in pressing down on the yarn package as it tends to collapse as the yarn runs out from the inside. This also eliminates rattling.

The drawings represent a shuttle having a hollow body B in which is a recess R to receive a yarn package P made up of thread T, the package being positioned in the recess R which has a bottom 3 and side walls 4 and 5, the inside faces of which are serrated. There is a thread eye E through which the thread T from a yarn package P passes, this eye being near the front of and passing through one side wall. The top of the recess R, shown as 8, is open.

For convenience, we will call the end of the recess and the shuttle where the eye is located, the front and the other end, the back.

A representsk a holding pin which extends transversely across the front of the recess R near its top and preferably is positioned nearer the Yfront of the recess than the eye E.

C represents a cover which is formed of a resilient material and comprises a shank l0 which as shown, is of uniform width and thickness and has at its front end Il a free tip I2 which, as shown, is curved and is intended to go under the holding pin A.

At its other or back end I3 cover C is curved around to form a substantially tubular integral pivot member I4 `and inside of this, We position a resilient lining F of cylindrical form, preferably made of a resilient material such as rub- 3 ber, neoprene or even nbre, with a pivot hole I through it, whereby pivot pin H can pass through the two walls 4 and 5 of the recess and through this hole I5 of lining F, thus providing a resilient pivot for a cover C near the back and top.

As shown, the bobbin recess R is extended at the frontttoforrn a holding pin part 2|) with straight side walls 2|, 2| andwith ilatbottom |23. The front holding pin A, as shown, is driven through one side wall 4 across this part of the reiV i cess and into the other side wall 5 above and over ilat bottom |23.

At the back bobbin recess R, isgexte/ndedltoY form a pivot pin part 23 With'side walls 21,21; which are preferably a distancecapart, slightly greater than the width of the cover C as are` also the side Walls 2| and 2| of thezholdingT pin part 20. These walls keep cover C'lo'os but laterally in place.

Extending through the side wall 4 is a two part pivot pinhole 24,v 25, which at,r Zllfv goes into pivot pin part 23 and thence as, a.A dead end part 25' in thesde wall 5., There is.; also preferably a pivot pin drive` hole2 extending therefrom out through the side wall 5.

In assembling-.theparts; the resilient lining E is florced'finto the substantially cylindrical Dill-OtV member I4 at;the..end! of cover C and both are placed vin position With lining hole I5 in therrlining with the pivotjpin, hole 24; 25, whereupon the pivot pin H is drivenithrough' the part 24 of thepin hole in thewood; and throughhole |5- in., the. lining F andv into the` part 25.- of the pin hole` so. thatrit; fitsA all'y of them witha driver frictionfit.

The resiliency of lining E as ',wellfasthe, tight fitting into thewood o the; shuttle keeps f the pin. frorrr` coming out ofv hole; part without the use of anyscrew. threads.nuts oranything of` that'kind'.v When it is. necessary. to replace a cover or a pin or any oth'erpartYV orwhen' the liningF loses its resiliency or. wears: down', a suitable smallldrive pin is'4 pushed into, drivel pin hole 26`-and hammered until the pivotv pin H is driven out. The pinH, lining F orcover, C or any or all of them can then beA replacedby another or by other parts.l

To installafyarn package cover-' C is bent as shown in the dotted lines Figil 2, Aand its front end II and free end l2 are removed from between holding pin A and the bottom! i231lof recess part 28 so that the -whole cover can be swung out of the way. A newpackagecan now be put in position andthe cover can be! swung down, bowed and its-end Ii pushedin under pin A and over and on to bottomI23l.

As shown in Figs. 2 and-3-, the cover-C when bent over a yarn package P and under holding pin A causes its end |2- to be held between holding pin A and the bottom |23 of recessZU and its resiliency and the resiliency Aof -the solid resilient lining F keep all metal parts inplace and prevent any rattling or vibrating which would tend to crystallize anyofth'e -m'etal'apar'ts We claim:
