HEDDLE.

Specification of Letters Patent.

Patented July 11, 1911.

Application filed July 11, 1908. Serial No. 443,129.

To all whomt may concern:

Be it known that we, WILLIAM'FEHR and JACOB KAUFMANN, both citizens of the United States, resirlngat the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have' jointly invented certain new and useful Improvements in Heddles, of which the following is a specication.

'- Our invention relates to heddles for loom harness and in such connection it has particular relation .to the formation of the warp eyethereoffinfthat type of heddles which are made from a thin flat strip of metal or wire.

-The principal object of ourfi-nvention is to provide an improved form of warp eye for that class of heddles which are made from a thin-flat' strip Aof metal or wire, the formation of the warp eye of our improved heddle being such' as to result in compa-ring operated up and down past the protrudingl shanksof the warp eyes.

The nature and characteristic features of our present invention will be more readily understood from the followingdescription taken in connection with the accompanying drawings forming part hereof, in which- Figures 1 and 2 are respectively face and edge view of a heddle embodying the main features of our invention; Figs. 3 and tare detail views, enlarged, of the eye portion of the heddle, taken respectively in the direction of thearrows aand y of Fig. and

- Fig. 5 is a horizontal medial section of the eye shown in Fig. 3.

= Referring to the drawings, in thc particular embodiment of our invent-ion there shown, 6 represents the heddle which is madefrom a thin flat strip of metal or wire and lprovided atl its respective upper and llower ends with the usual ,mort-ises S for mounting the heddles on the harness frame rods, not shown. Intermediate the mortise 8 the heddle is provided with the warp eye 9, the conformation of which is the subject matter'of this invention. The Shanks 15 of the eye 9 'are each bent slightly. outward from the general plane of the eye portion 10 in opposite directions to each other as clearly shown in Fig. 4', and the shanks 15 of the 'eye 9 may if desired, be expanded laterally as shown in Figs. 1 and 3, butthe ends of the eye 9 however are interiorly Arounded .as at 12. The eye portion 10 is twisted to occupy a position at a slight angle to the main planey of the heddle, the twist occurring immediately above and below the eye 9 and being in the same angular direction ,as the bend -or offset of the shanks` 15. By this arrangement the rounded'ends 12 of the eye 9 although the shanks 15 thereof are only slightly bent out of the plane of the eye pori tion, will nevertheless be in such position, due to the angular arrangement'of the eye portion 10 as to present relatively large and broad bearing surfaces which will permit of the ready passage of the warp and of knots therein through the eye 9, as will be f readily understood by an inspection of Figs.

2 and 5, the line 14 of Fig. 5 indicating the direction of the warp in its passage through the eye, and no abrupt shoulders will occur in the outer margins 16 of the warp eye.

It should be understood that in the manufacture of heddles from a thin flat strip of metal or wire as contradistinguished from those, made by punching from sheet metal, on account of the limited amount of cross sectionof the materia-l which is available, certain difhculties arise in order to secure the proper conformation of the warp eye, Awhich difficulties it is the purpose of the present invention to overcome. `l-Ieretofore when it `has been required to make a relatively large or wide eye in a heddle madey from a thin narrow fiat strip, if the Shanks were benty out of the plane of the heddle in a smooth eyfen curve, asharp notch Awould occur at the"`top and bottom of the eye which would tend to bind the warp and prevent the free and easy passage of the same therethrough, while if this objection was overcome by bending the Shanks abruptly at the Awhich threads are controlled by the other harness frames of .the loom.

By twisting the eye portion immediately above and below the eye to a slight extent only and by bending the Shanks of the eye slightly, in opposite directions to each other and in the same direction as the twist out of the plane oi the eye portion as hereinbet'ore set lorth, the aforesaid object-ions are effectively overcome, the eye being thus sutticiently enlarged, the top and bottom being provided with enlarged and'roundedbearing portions for the passage of the warp, and the exterior margins of adjacent heddles offering no abrupt obstrutions to the free movement of the warp threads which lie therebetween.

Having thus described the nature and characteristic features of our invention what we claim as new, and desire to secure by Letters Patent is l. A. heddle made from a thin tlat strip of metal or wire haiiing' a warp eye formed by bending the shanks thereof out of the plane of the eye''portion in opposite directions to each other; the eye portion being twisted im.- mediatelyf'aboye and below the bent Shanks thereof in the same angular direction as the offset of the shanks, and the interior end margins of the eye being rounded to form large bearing portions for the warp which passes through the eye.

2. A heddle made from a thin flat strip of metal or Wire having a Warp eye formed by expanding the Shanks thereof laterally and bending the same out of the plane of the eye portion inopposite directions to each other, and the eye portion being twisted immediately abovev and below the bent Shanks thereof in the same angular direction as the offset of the shanks. l

In witness whereof, we have hereunto set our hands in the Apresence of two subscribing witnesses.

WILLIAM FEI-IR. JACOB KAUFMANN.
