TEXT ILE APPARATUS F11ed Aug. 2 5, 1957 7- q 16 if 16%? tllgl 'Illa Patented Feb. 14, 1939 UNITED This invention relates to textile apparatus.;

and it relates more particularlyl to improved means for spacing .metallic strips, such Vas thev` dents of combs andreeds used in various textile o-perations; and it is also applicable in some instances for maintaining the separation of flat steel heddles used in loom harness.

Heretofore various forms of spacingV devices have been used for spacing or separating thev dents of combs andreeds used in-textile'opera-f` tions, and for maintaining la minimum amount.

of separation of iiat steel .heddles used in`1oorny However, none of these devices `havey proved entirely satisfactory under all conditions.`

harness.

The `principal object of `the present invention is to provide means for maintaining `the separaf: tion or spacing of metallic strips used invtextile4 apparatus, such as the dents of combs'andreeds,4 and the heddles of loom harness, which` willbe relatively inexpensivey yet entirely eiiicient for the intended purpose.-

A further object of the invention isfto, provide means for maintaining the separationorg spacingA of such ymetallic strips, in the-use vo-f whichthere` will benotendency to bend-or ex vthe metallic strips adjacent the separating device- Arfurther objectrof the inVentionIisto provide separating or spacing meansfor. such metallic strips, vin the vuse of which there will be no torsional strains set-up which would. tendfto twist the strips out of their proper parallel4 planes.

A further object of the invention .is 'to4 provider separating or spacing .means for such: metallic strips which: mayv be .readily incorporated. in said strips, at the time of their manufacture, by ordinary punching and forming operations.

The nature and characteristic featuresof the.

invention will be more readily understood from 40 the following description taken in connection with the accompanyingdrawing forming part hereof, in which: Y

It will, k,ofeolllf8,1-,,be understood A-that the drawing-and description-herein contained are illustrative merely,ffandwthatfnvariouschanges and 10.

modifications maybemadeinf-the structure disclosed withoutfdepartingfrom the #spirit of the inventionr- Referring .tothe drawingv,`-with particular reform or construction-.of areed-,orcomb I0 usedv in variousA `textile operations, ,asm-rior example, for guiding ethe warp toor from alslasher. .Said device consists ofi-a; suitableaframemll, .having sidevstrutspI-Z, and disposedbetween saidside 20V struts f- I 2,-I spacinggdentsfl 3,- and plain.A dents I4 are mountedinalternaterelationship; said dents being rigidlyfsecured-,at theiiilower ends in thel frame I0 in the usual manner of construction of soldered reeds. l.- f

As.,there ,showing,each of.,.the ,dent-sgI 3v and I Il` comprisesasthnvflat.;strip oimeta1, the dentsr I3 being. eachlprovided, adjacent. theiree ends thereof, with la spacingndrevioe .off peculiar i ormation.` Said spacingdevice is'iormed byffsplitting 30 the I metal of f .the dent. .at., a place where said, spacing Ldelvice tothe f located, thereby-.to vprovide three longitudinal strips.. The central strip I5 is pressed and formed out of Vthe main `plane of the.. dent I3,.;a.,dis,tance .corresponding tothe 35 amount 'ofLseparationmequired.l Likewise, the sidestrip`s|6are also ,pressed and formed out of the main plane ofthe dent I 3"but in a direction opposite to that .of 'the.central stripI 5.V

The dents; are mounted in the frame .inalter- 40 nate relationship, that vis to say,.,a spacing dent I3 fis Ain Teach ,instance` VdisposedJoetween `a pair of plain,- dentsf `I 4.", It vwill .be ,noted thatY by this arrangement,. with, reference particularly toA Fig. 4 of the drawingjeach ,ofthe side` strips I6 -of 45 the spacing device will'bearagainst the face of one of the adjacent dents I4 in symmetrical relationship, Whereas the central strip I5 of the spacing device will bear against the central portion of the face of the other adjacent plain 50 dent I4. By this arrangement, there will be no torsional strains set up which would tend to twist any of the dents out of its normal and proper plane.

It should also be noted that the strips I5 and 55 IG, constituting the spacing device, which are provided on the dent I3, will have flat portions of sufficient longitudinal extent and disposed in planes parallel to the main plane of the dent, so that there will be no bending strains set up in the dents which would tend to distort or flex the same adjacent the spacing device.

It will, of course, be readily .understood that the invention is equally applicable for the spacing of metallic strips in other textile apparatus, whether the same be mounted rigidly in the frame, as is common in certain reeds and combs, or whether the same be mounted in expansion types of reeds and combs, or for the maintaining of a minimum spacing of the heddles used in loom harness.

In Figs. 6 and 7 of the drawing, there is shown a modied form of the invention as applied to the heddles of a loom harness frame. In this instance, all of the heddles I38L are provided with a spacing device adjacent the place where they are mounted on the heddle rod I8, andthe plain uniformed members are omitted. However, each alternate heddle is turned with respect to the others so that the longitudinal strips I6 at the sides of a particular heddle will bear against the longitudinal strip I6 at the sides of an adjacent heddle, and likewise the central longitudinal strip I5 of a particular heddle will bear against the central longitudinal strip I5 of the outer next adjacent heddle. Also in this form, in which the intermediate plain members are omitted, the spacing strips I5 and I6 will bev pressed out of the main plane of the heddle a distance corresponding to but one-half of the amount of the minimum separation desired.

It will, of course, be apparent that the form of the invention shown in Figs. 6 and '7 of the drawing is readily adaptable for use in various forms of textile combs and reeds, and that likewise, the form of the invention shown in Figs. l to 5 of the drawing is adaptable for use in connection with certain forms of heddles used in loom harness.
