v The oibjectof.

Y y invention isnto improve v`theconstructionpoli a loom r` shuttle, whereby tliefshuttleisipro r,ided with asimple, durable l .hand threading'.A device adaptedfito facilitate thc threading :of tthe iMy inventioi'i consistsin thepeculiar-aiid nevel?y construction of thedelivery end of a loom 'shuttles-andi mechanisml for threading theshuttle by hand, as will be more fully set forth hereinafter and claimed.

Figure 1 is a top plan view of the thread delivery end of my improved hand-threading loom shuttle. Fg. Lis Aa side view offy the de 'livery' end. of the shuttle looking atthe de# livery eye side. Fig. Sis a longitudinal sectional view through the delivery end of the shuttle taken on line 3 3 of Fig. 1. Fig.. 4

36 is a ,transverse sectional view through the shttle taken on line 4 4 of Fig. 2 looking toward the end of the shuttle. Fig 5 is an enlar ed side view of the inner'threading meiner, and Fig. 6 is an enlarged perspective view of the outer or guide eye member of the threading mechanism.

ln the drawings., a indicates the thread delivery end of a loom shuttle, t the bobbin, c the bobbin cavity, d the throat, e a cavity at 46 the vend of the throatd extending from the top of the shuttle downward to thi` center of the shuttle and. opening into the throat d, f a

circular recess in the side of the shuttle, g, a round transverse hole extending centrally from the depression f into the cavity e, t .an

inclined transverse slit extending from the top and side downward toward the point to the center ofthe shuttle and into the circular cavity c, 0' a longitudinal slit extending in v'5S from' the side of the shuttle to the ca vity e and intersecting theslit h Aand the hole g and forming with the slit 71, a wedge-shaped roiection k, l a small ofi-center vertical ole extending downward from the bottom of the cavity c, m a small transverse hole extending uiity of Bristol and Stateof ye invented a new and usei f ,inward from the .circular recess f under the hole g, n the inner threading member, and o .l the guide eye member of thethreadingmeeh..

anism. I

-The inner threadin member n is formed of wie-.c shaped to'havet c straight shank 7 and 1 thepointed end ,8 bent at riglitangles to the shank, as shown in Fig; 5. The shank 7 "is bottom of the cavity e and the pointed end 8 forced into the Wedge-shaped projectionk, as

shown in Figs. Sand 4. The guide eye member o' is formed from wire shaped to have the .straight shanky Q'and the circular coiled end Ghent at right angles to the shank and havingxthe reduced vend'll slightly clearing the basev of the coil and forming an opening 12 between the end 11 and the baseof the' coil,

as shown in Figs. 2 and 6. The shank 9.i s

driven into the small transverse hole m in a position to bring vthe coiled end' 10 into vthe circular depression f, as shown in Figs. 2- and 4.

ln threading the shuttle the thread is first e and depressed into the cavity e, then carried into andthrough the slit h into the slit t, and

from which'point it iscarried under the reduced end 11 and throu h the opening 12 into the coiled end 10 oft e guide eye member o which forms the delivery eye of the shuttle. The thread 'now runs from the bobbin b' around the inner threading member 'a vthrough the slit 'i and hole g and out through the coiled end 1() of the guide eye member o. The thread is now prevented from returning by the lower edge of the circular depression f holding the thread away from the opening 7c -in the guide eye member o.

I claim as new and desire to secure by Letters Patent 1. A shuttle body having a cavity' at the end of the throat, a transverse holeextending in and from the side to the cavity, a thread passage in the form of a slit extending from the top and side downward at an angle and then back longitudinally into thecavity and transverse hole, an inner threading member having a straight shank driven -downward into the bottom of the cavityand a pointed end forced into vthe wall ofthe cavity, and a guide e. e member in the transverse hole in the s uttle.

pulled from the bobbin bever. the cavity,`

then through the slit iinto the depression Q7 driven downward into the small hole-Z in the' Having thus fully described my invention,

2. A shuttle body having a cavity at the end ofthe throat extending from the top of the shuttle downward, a transverse hole extending from the side of the shuttle inwardly to the cavity, a thread assage inthe form of a slit extending from t e top and side downward at an angle toward the point of the shuttle and into the cavity and: then back longitudinally toward and into 'the cavity and transvers e hole, forming a wedge-shaped projection'in the wall of the cavity, an inner threading-member having' a straight shank j driven downward into the bottom of the cavity, and-fa pointed end bent at right angles and forced into the wedge-shaped projec-v tion, and a guide eye member inthe transverse hole in the shuttle.

3. A shuttle body having a cavity at the 1 end of the lthroat extending from the top of tle and then back longitudlnall toward and into the cavity, the recess and t e transverse hole, forming a wedge-shaped projectionin the wall`of the cavity, an inner threading member having a straight shank driven into the bottom of the cavity and a pointed end bent a't right angles and forced into the wedge-shaped proJection, and a guide eye member having a straight .shank anda coiled end bent at right an lesand` secured by driving the shank into t e transverse hole in the shuttle in a vposition to bring the coiled end into the .circular recess in the side of the'v shuttle. y

4. The combination with. a shuttle body having a'bobbin cavity c, Va throat d, a cavity e at the end of the throat d, a circular recess f in the side, a transverse hole' g extending from the recess f the cavity e, an inclined slit h extending from the top and side downward 'toward the oint of the shutt1e"and into the cavity e, a ongitudinal slit 'i extendingl in from the side of the shuttle to the cavity e and intersecting the slit hand the hole g and forming with the slit h a wedge-shaped projection k, a small oil-center vertical holeZ extending downward froml the bottom of the1 cavity e, and a small transverse hole m ex-` tending inward from the recess f under ythe hole g, of an inner threading member n hav-- ing the yshank 7 adapted to be driven into the vertical hole l anda pointed end 8 bentv at right angles andadapted to be forced into the wedge-shaped projection 7c and a guide.. eye member o having the shank 9 adapted to be driven into the transverse. hole m, and a coiled end 10 bent at right angles tothe shank and having the reduced end 1 1 and th;

opening 12 and adatedto enter the recessf in the side of the s uttle and form the d e`` livery eye of the shuttle, as described.

In testimony whereof I have l signed'my name to this specification in the two subscribing witnesses.
