Application filed September VIEFT GAERXER.

To all 'wil' om t may conce/Mi:

Be it lino-wn that l, OLIVER Siiiiiwnnii,

a subject of the King of Gre ireland, and resident of G- at Britain and a wsworth 'O id Hall, Gawsworth, in the county of Chester, England, have invented certain new and useful linproveinents in llVeft Carriers,` or

which the following is a sp eciiication.

This invention relates to shuttleless looins for weaving-g of the type in which the weft draws a length of yarn through the rarps and has for its object to provide simple and efficient ineans for ensuring that the weft shall be laid straight and correctly tensioned in position and shall notcurl when released by the carrier and so produce short ends.

accorrance with iny invent-ion, each hook or the like upon the weft carrier .which takes over the looped weft thread anc draws o i end thereof through the warns, is so disposed and arranged in combination with :i slot or groove in the carrier that as the latter iuoves through the warps, it directs the weft thread to the underside of the Cri the weft upon the warp thre The latter therefore lays or irons ads un der tension but because of the natural adhesion of the weft and warps after such ironingl process, the weft reainins straight and tensioned when its end coines clear of the carrier at the end of the stroke of the latter.

It will be understood that the carrier has weft lioolrs and grooves at both ends lso that it operates in both directions of its traverse. v

The hook in the carrier i s of the forni which provides a point beneath which the weft thread is depressed and raceway beneath such point thread travels whilst it is gui a closed ended in which the ded by the slot in the carrier to the underside of the carrier in the inanner before referred to.

Referring to the accompanying sheet of explanatory drawings z- Figure 1 is a side elevation, Figure 2a plan, Figure 3 a side elevation partly in section, Figure a an inver ted plan and Figure 5 across section (on the line A. B. Figure 3) illustrating a weft carrier constructed in accordance with Figure 6 is a plan (with this invention. a portion reinoved) showing one of the two thread engaginghooks of the said carrier. `Figures 5 and@ are drawn to a lar Figures l to 4.

ger scale than 2, i924. Serial No. 735,432.

Figure 7 is a perspective view of one of the said engaging hoolrs.

The saine reference letters in the different views indicate the same or siinilai' parts. 60 rllie wood body a of the weft carrier has a thread groove Z) at one side of its upper surface into which the weft thread is depressed by the depresser foot of the looin. At the other side of said upper surface there are attached (by screws as c1, Figure 2) two weft engaging hooks c facing in opposite directions.` The weft thread, when engaged by a hool: is directed down a raceway d, forined integrally with the hook, and through a gap e providing a communication between the groove and the lower surface of the carrier. Assuming, for enainple, that the weft `carrier with the looped weft thread f, g, therein is travelling froin left to right through the shed of warp threads, the weft thread will pass, from its position ,f in the groove h under the right hand hook c, and thence through the raceway cl and gap c to the position g on the Vunderside of the carrier. As the carrier engaged by said hoolrs is directed beneath 95 the said body and pressed upon by its under surface. i v

2; A weft carrie-i` for shuttleless looins, coinprisiiie' a body part, two weft thread engaging)` hooks facingin opposite directions secured to the upper surface of the said body, and ineans consist-ing in part of raceways formed integrally with said hooks whereby the thread engaged by the hooks is directed beneath the said body and 105 pressed upon by its under surface in its inovenient along said thread.

8. A weft carrier for shuttleless looms, comprising aV body part having a weft thread groove extending along` one side of 11o its upper surface, two weft threadhengaging hooks facing in opposite directions secured upon the other side of Said upper position beneath the. said body to be pressed surface, gaps vproviding communica-tions upon by the under surface of the latter n between said groove and the under surface itsrlnovement over said thread. 10 of the body part, and raeeways formed In testimony whereof 4I have signed my integrally with said hooks whereby the name to this'speocatom thread engaged by the hooks is directed Y from said groove through said gaps to fr OLIVER SHIMVVELL.
