HEDDLE Foe LOOMS.

To all whom it may (2097( '67'72 V Be it knownthat I, ;r AUL A. WAGNER, a citizen of the United States, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented a certain new and useful Improvement Heddles for Looms, of which the following :is a specification.

* The object of the invention is to provide a light, economically manufactured heddle, having the required strength andfiexibility and adapted to serve eficiently with the warp threads and loom harness; The invention consists in certain novel features of-construction bywhich the above objects are attained, to be hereinafter described and claimed. V

The accompanying drawings form a part of this specification and of the invention;

Figure 1 is a' face view of a preferred form of the-improved heddle, on an enlarged scale. i 1 V 1 a 'Figure 2 is a face view=on a still larger scale and shows the construction ofthe warp-eye as in Figure 1, and is partly in section; i va 7 Figure 3 is a transverse section through the warp-eye, taken on the line 3+3 in FigureQ. m r a I Figure dis similar view taken on the line 44, throup'h a portion offa mail. servmg to re nforce such eye.

It'is partly in section.

rounded edges for thevheddle, and V .twolayers of paper joined face to face. The

heddle 'eyes and warp-eyes are formed by slitting and spreading the folded strip properintervals, and the eyes are reinforced by suitable, imails introducedbetween the ferred material, cotton, linen, silk orother 'fabricstifi'ened by suitable sizing or cement cessfullyi.

with any suitable waterprooficement,:folded longitudinally upon itself along both mar gins withits edges abutting along the censtrip 'is slittedon such line at proper intertthe drawings, Figuresto i ln'cluslve, l2isast'rip of paper coated:

"and similarly folded, may be-employedrsuctral line. In the'process of manufacture the r i vals, and the'edgesofsuch slits, andthe abut-ting edges of the strip at points "coinciding with the slits, are separated to form eyes.whichare reinforced by mails. The mails at the ends of each' heddle are shown as plates 13 of metal or other wear-resisting material, each having a central slot 14 serving to receive the heddle bars, not shown; anda similar but smaller mail,-not shown, maybe introduced at the midlengith to serve as areinforcement for thewarpeye. V I I i v It is preferable to form the malls for the Warp-eyein separatehalves 15, see Figures 1 and 2, each a plate having one end 16 hollowed into crescent shape, placed in the strip in separated pairs with the curved ends '16 presented toward each other,'.one at each end'of the warp-eye, and smoothly rounded to receive a warp thread between them.

' In-order to increase the tensile strength of the heddle, strands 17 'which'may be threads or cords'are'laid in the bightsof the folds and held by thecement'in the process of manufacture, extending the full length of the l1edd-le,'ahd as an additional" reinforcement,longitudinally extending ti-laments2'7 of silk or other strong fibres are cemented on the surfaces of the strip, as in-.

dicated in Figure 2.

In the form of the invention shown in I Figures 5 to '8'1nclus1ve the marginsof the strip-are folded unequally longitudinally so that-the abutting edges come together ona line at one side of the centre, as at 19, and. the bight of the wider fold is cutaway at 20 to receive a warp-eye formed in a plate shown lying in the bight of the narroy fold.

,The modification shown in Figure 11 1S similar to that just described, but'the offset portion of the plate or mail 25 projects beyond the margin of the heddle through a slit in the bight of the wider fold.

Figures 9 and 10 show a mail formed by a closed. loop or link 26 of wire, flattened as in Figure 10, and adapted to serve as a.

substitute for the separated mails 15 in Figures. 1- and 2 or for the mails 13 for the heddle bars.

The finished and dried heddle thus constructed is light, strong, and sufficiently flexible, and may beexceedingly thin and narrow and 1s easily and cheaply manufactured in continuous lengths by suitable machinery, and subsequently cut to produce the individual heddles shown.

Other modifications than those substituted for the strands 1'7 and 24;, the filaments 18 may be omitted, and the forms and proportions of'the parts varied as conditions of service may require.

'14. A heddle composed of a flexible strip folded longitudinally along both margins and cemented with both edges presented on the same face, slits in said strip in coincidence with the joint along such edges, and mails inclosed by such folds and serving to reinforce eyes formed by separating the margins of such slits and joint:
