T 0 all whom it may concern:

Be it known that we, EDGAR F. ILTHA- war and Cm LEA, both citizens of the United States, and residing, respectively, at Dorchester and Boston, both in the county of Suffolk and State of Mamchusetts, have nvented an Improvement in Detached Heddles and Means and Methods for Assembhng and Handling the Same, of which the fol lowing description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

Our inrenticn relates to the assemblage 1 independent detached. thread-engaging,

loom elements, such as the detached heddles of'a metal h-arne m, dropwires or drop heddles, or other like devices the independent members of which are required to be placed in operative association with one or more ihreadsof a loom warp to fulfil some inlnded purpose in the operation of the loom.

Our invention has for its object the as semblage of a series of heddles, or other like defice, in such relation that their tion for any desired purpose, such asthe placing of warp threads through or the control of successive members of the assembled series may be readily efiected, while at the same time they may be installed in the loom in their assembled state and perform their usual functions.

These heddlcs or drop bars as ordinarily constructed are formed of thin sheet metal stri or plates, and are held in an assembl compacted series face to face and with their thin edges exposed. In order to facilitate their separation when asenibled in serics, it is common to arrange them with an alterna 'variafion in form or position, so that suits le aparating mechanism acting with reference to such alternating variation can readily release and separate successive members while holding back the remaining members of the series.

Where an alternately varying formation is procured by removing portions of the heddles or drop wires, either in the form of perforat-ions. indentations in the edges of the heddles or other like formations, such perfomtions, indentations or" other formations, if arranged in aliuemcnhns' customarily has been done to provide a continuous passage or channel for the reception of a separating member, also present such passage or channel for the entrance and accumulation of lint and the like if the heddles or drop bars are installed in the loom in the same relation. This is particularly detrimental in the case of drop heddles or drop wires, which are intended to undergo no movement relatively to each other, except on the breakmg of a thread. It has been found that the accumulation of lint in the p formed by perforations in thesuccessire eddles as describedtends to fill up such passage and sustain the heddle independent of the support afiorded by its thread, so that if the thread breaks the heddle may fail to drop and perform its intended function.

The object ofour invention is to prevent such conditions and to thisend we have provided an assemblage of hcddles, drop bars or the like presenting perforations, indentations or other formations rgularly alternatingnin form but presenting portions adapted to brought into line to receive some memher of the separating mechanism of a warp drawing or other machine, which perforations, indentations or formations, however, may be put out of alinement when installed in the loom so as to leave no continuous channel or pasage forthe accumulation of Our invention will be best understood by reference to the following description when taken in connection with the accompanying illustration 'of one specific embodiment thereof, while its scope will be more particularl; pointed out in the appended claims.

In the Figure 1 shows in side elevation a, common form of drop wire or hetiltdlle 2 the:1 samei heddle prov1 an a an a re easmg o ing; Fig. 3 shows a similar heddle with $e releasing opening differently positioned to give an alterna arrangement; Fig. 4 shows in side elevation an assemblage of heddles, alternate members of which are perforated. as are the heddles shown in Figs. 2 and 3; Fig. 5 is a side View of a portion of the series shown in Fig. 4; Fig. 6 is an end elevation showing the heddlcs with the releasing openings brought into alinement; Fig. 7 shows the same heddlcs in side elevation; Fig. 8 is a side elevation of the series illustrating the operation of the releasing mechanism thereon; Fig. 9 shows the same series of heddles coiiperatively related to the separating mechanism of a drawing-in machine; Fig. 10 is a detail showing the action of the separating mechanism; and Fig. 11 is a detail showing the releasing key.

For the sake of illustration, we have herein shown our invention as applied to one parncumr type of drop wire or heddle, customarily employed for stop motions in connection with the warp of the loom. It is to be understood, however, that this invention has'not only general application to drop wires or drop heddles of widely varying and different types or constructions from that shown in the drawings (which is selected solely for the purpose of concrete illustration,) but also has application to the heddles of a metal harness and other similar detaehed' thread-engaging loom elements. Beferring to the drawings, however, and the specific embodiment of our invention there selected for illustration, there is shown in Fig. 1 a well-known form of metallic drop heddle, the same consisting of a thin, resilient, sheet-metal plate 1, aving a threadreceiving opening 2, herein (though not necessarily) in the form of a circular perforation and having also a portion such as the elongated eye- 3 shaped to receive one of the usual contact members in the loom and herein also employed to remive the supporting bar i (Fig. 5), upon which the heddles may be held in assembled series prior to placing the threads through the thread apertures thereof and installing the same in the loom.

In the disclosed form of heddle we have provided an alterna a variation in form between successive hed es, herein by perforating the heddle as at 5 (Fig. 2) and proriding a lateral enlargement 6 of such perforation, the 'enlargementextendjng in one direction in the cam of one heddle and (Fig. 3) in another direction in the case of the next adjacent one. For example, in the case of the heddle shown in Fig. 2, the enlargement projects upwardly, and in the case of the heddle shown in Fig. 3, which is the next succe$ive heddle, the enlargement extends downwardly in the opposite direction. This alternating variation in the formation of the releasing openings in successive heddles makes it pomible for them to be engaged as represented in Figs. 8 to 11 by a releasing and separat' key 7 connected to the releasing rod 8, e latter extending through the channel or passage formed by the perforations 5 in succemive heddles of the assembled mas.

While our invention is not limited to any particular form of separating mechanisnnto best understand the utility of the releasing openings, reference may be had to the operation of the separating mechanism shown in Figs. 8 to 11, where the head 7 of the releasing key is provided with an abrupt shoulder 9, which in its operation is caused to overlie and press against the face of the foremost heddle of the compacted series (see Fig. 8) and hold it back together with the rest of the series. As the key is turned, the shoulder 9 is finally turned into registration with the elongation 6 of the releasing perforation for the foremost heddle, and the latter is thereby released and permitted to pass over the head of the releasing key,- the next successive heddle, however, with its oppositely directed elongation, continu ing to press against the overlying shoulder of the key and, together with the rest of the series, being held back thereby until the key. executes another half turn. It will therefore be seen that the releasing rod, while holding back the body of the heddles, at each half revolution releases the foremost member of that body of series.

The head 7 is provided with a helical formation 10 which is adapted to engage thi released heddle and force it along to the extnemity of the head where it is discharged. As representedin Fig. 9, the heddle may be discharged to any suitable positioning mechanism, such, for example, as the positioning worm 11 adapted to be rotated by thcworm shaft 12, which, together with the key rod 8, extends to suitable actuating mechanism, not herein shown. The positioning worm 11 is so formed as to receive the heddle when discharged from the key, and, after advancingihe same, to give it a half turn to place its threading opening 2 in line with the drawing-in needle or other implement, which is qualified to place a warp thread through the same. Discharge of the threaded heddle from the worm to the series of already threaded heddles follows, and, in this fashion, the releasing key, positioning worm and drawing-in mechanism is caused to advance across the series of heddles.

In order better to effect the release of the successive heddles when the shoulder 9 is brought into registration with the elongated portion of the releasing opening, there may be rovided means, such as the carriage 13 which has a curved edge 14 pressing against the end heddle of the series, so as to bend their upper or top ends all slightly outward and thus impart to the foremost bar a tendency to spring over and along the key head 7 when the bar is released.

In order that the releasing openings may be out of alinement when the heddles are installed in the loom, and the formation of the resultant channel or passage thereby prevented, the said openings are not only given an alternative variation in form as between succesive members, but are also supporting threading openings will be substantially in alinement', while-the series of releasing perforations will be offset from each other and vertically out of alinement, the relatiw. positions of the successive releasing openings being represented in Fig. '4.

In order that the threading openings may be in substantial alinement when the beddies are suspended on the supporting bar 4, so that, for use in the drawin -in machine, each threading openin will oe in approximate alinement with t e drawin -in needle, the upper inner edge of the e ongated eye 3, which acts to support the heddle b v resting on the supporting bar 4 is spaced equi-distant from the threading opening in successive heddles, but differentially from the releasing openings, as will be seen by the contrast between the heddles of Figs. 2 and 3. With the heddles assembled, therefore, as shown in Figs. 4 and 5, and suspended in a compacted mass upon the supporting bar 4, the releasing openings are ofi'set from each other and out of alinement.

In order to aline the releasing openings ofthe-assembled heddles for the reception of the key rod 8, we have provided suitable alining means. \Vhile this alinement may be provided for in various ways, herein we have provided as an alining formation for each heddle, the circular enlargement 15 'near the bottom of the elongated eye 3. These comprise in efiect openings of substantial" the same diameter spaced equidistant from the releasing openings 5 in the case of each heddle, but differentially spaced in successive heddles relatively to the threading openings 2. \Vhile the alining openings in successive heddles are out of line as the heddles hang upon the supporting bar 4, they are so arranged that -successive alining. openings overlap leaving a continuous channel 16 (Fig. 4) through the assembled heddles of slightly greater width than the eye 3.

\Vith the bar, an alinin member 17, comprising a rod of substantially the diameter of the alining openings 14 and having a tapered point 18, may be inserted in the widened channel 15 and forced through the entire series'of heddles, as indicated in Fig. 7 this operation causing successive heddles elevated heddles are released and drop wires assembled on the stalled in the channel formed by the perforat-ions 5 and itsend connected with the driving mechanism in the machine preparatory to the separating and selecting oper ation, the alining member 17 thereupon being withdrawn (see Figs. 8 and fl) leaving the series of heddles in condition for the separating and drawing-in operation. During the separating action a portion only of the unthreaded heddles rest upon the supporting bar, each alternate one being supported at the key rod 8. .-\s-the alternate discharged from the kev rod, they are dropped to a lower level and, in their subsequent movement, are suspended upon the supporting -bar 4.

\Vhile we have shown and described one specific embodimentof our invention and have shown for sake of illustration one spe cific application thereof, it is to be understood that our invention is not limited to the particular details herein shown or to the application thereof herein made. but that it is susceptible of extensive modifica: tion and deviation from the described construction, and may be usefully applied to purposes other than those herein described Having thus described ourinvention,\vhat we claim is:
