' Specification of Letters Patent.

Hannan.l

tPatented nur. til, t n iis,

To all lwhom it may concern Be it known that L'JAo-on KAUFMA'NN, a citizen ofl the United States, 'residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Heddles, of which the following is a specification.

My invention relates to heddles for loom harness in which the major portion of the heddle is made from a thin flat strip of metal or wire and having means carried at the ends thereof for mounting the heddles on the harness frame rods.

M v invention also contemplates a construction whereby one or more heddles may be mounted in the frame, either for the purpose ot replacing a broken or damaged heddle or where it is desired to increase the number ot heddlesy in the frame, Without 'dismantling the rods from the harness frame.

' The nature and characteristic features of my invention will be more readily understood from the following descriptiontaken in connection with the accompanying drawings forming parthereof, in which- Figure lis an edge view of a heddle embodying the main features of my present invention, andI tho same being shown mounted on the rods of the harness frame; Fig. 2 is a face'view of the heddle shown in Fig. 2, .the harness frame rods being shown in section; and Figs. 3 and 4 are respectively edge and face iews, enlarged, of the ends of the heddies shown in Figs. l and 2.

ln the particular embodiment of the inlvention which is shown in the drawings 5 is the main or body portion of the heddle which is made from a thin fiat strip of metal or wire and in which the warp eye (l is formed by slittino and expanding in any preferred manner; Near each end ot the strip 5 therel is' provided an aperture 7 in which is arranged a wire loop S, the loop S constituting the means for mounting the heddlc on the rods l) ot the harness traine. 'lho loops 8 are preferably made olf round hard wire having thei r ends l() and il abutting or overlupi'iing as clearly shown in l `igs. 3 and Il, thi` ends l0 :ind A1l boing capable of being readily spi-turnr apart so that the loops t5 constitute in ell'oct spring snap hooks whereby the heddles may be readily mounted on the rods in any desired location without dismantling the rods from the trame. At the portion of the loop 8 contiguous to thcpart thereof which engages the aperture 7 of the strip 5, the wire constituting the loop 8 is bent in such manner to form shoulders 12 and 13 to abut or bear against the end of the strip 5 and thereby )revent twisting ot the strip` relatively to t e loop 8 and consequently with respect to the rods so that the strip 5 will always be maintained in a plane parallel to the general extension of the warp which passes through the eye 6 and is controlled thereby, the shoulders 12 and 13 of the loop 8 at one end of the .st-rip serving to prevent rotation in one direct-ion and thecorresponding shoulders of the loop 8 at the'other end serving to prevent rotation in the other direction.

It will be seen that. there is provided a heddle in which the major portion thereof may be made of a thin liat strip of metal or wire ot' relatively small cross-section whoreby but little interference will be had `with the passing warp threads during the actuation of the harness frames, but in whirh'tho loops for mounting the heddles on thi` harness frame rods may be made of thi desired size or outline in those cases wherefit is necessary to make the rods of consiiflerable thickness and width, as for example ,in wide installations'. lt will also he seen that. by the construction of the loops 8 as hei-einbefore set forth one or more of the beddles may be readily inountedat any desired position in the sliat't without dismantling the: rods from. the frame. i

l-laving thus described the nature and characteristic tentures of my invention what l claim as new and desire to secure by lietters Patent is:--

l. l lu-ddlc made from a thin llatI strip of metal or wire having apertures in the ends thcrro't' and wire loops arranged in said aperturesl for mounting the heddle on the Izarness tramo rods. said loopsl being bent to torm shoulders bearing against tho side faces ol' the strip to prevent rotation of said strip with respoit to said loops.

2. Harness t'or looms comprising supporting' rodsv` a heddle made from a. thin lint strip ot metal or wire having; apertures in thc ends tbereot'. wire loops nrrangedlin said apertures eurh-havinga portion surrounding the supporting rodsF said loops being lll bent to form shouldersbearing against the sido faces of the strip to thereby prevent rotation of the, strip with mspect to said loopsi and said loops having contiguous ends 1n the rod. surrounding portion adapted t0 be sprung apart for' mounting the heddle in. the harness.

In testimony whereof I' have hereunto signed my name in the presence of 'two W1t- DSSQS. J ACOB KAUFMANN \Vtnesses: n f n VILLIAM S. ATCHISON, RALPH H. GAMBLE.
