DETACHED HEDDLE' OR THE LIKE.

To alljwiumt itmay. concern Be it known. that I, CHARLEs- E., BLAIR, a. citizen. of the United States, and a resident of Dorchester, county of Suffolk, State of hilassachusetts, (whosepost-oflice address is 195 Freeportstreet, Dorchester, Massachusetts,)- have invented an'lmprovement in.

Detached. Heddles or the like, of which thev following description, in; connection with the accompanying drawings, is a specification, like characters on thev drawings representing like. parts This invention relates to independent. or detached heddles, drop wires, or the; like, and more particularly to the construction of said: heddles so'that they may be assembled in. an; organized series capable of ready selection and separation either by hand or by mechanical devices.

This application is a division of my prior, copending application Serial No. 474,885, filed May 8., 1909.

The 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 particularly pointed. out in the appended. claims.

In the drawings: Figure 1 shows anassemblage of detached heddles or drop wires constructed and arrangedin accordance with one form of theinvention and shown in cooperative relation to mechanical separating or. releasing devices; Fig. 2 islan elevation of, a metallic heddle or drop wire. with the.

associated devices shown in cross section; and Figs. 3, land 5 are. diagrammatic viewsillustrating the internal variation in form of successive heddles and the. relation thereto of the separating or releasing devices at different stages of their operation.

Referring to the drawings, I have. shown the invention embodied in the form of detached heddles of the kind usually formed of thin,.resilient sheet metal and employed in the loom as: drop heddles, but the invention contemplates independent, detached heddles of other. forms of construction and also similar loom elements, such as drop bars or drop wires, the term heddle being used as a generic term to include those. devices as well.

In the specific form of the invention illustrated it will be seen that the heddles or Specification of Letters Patent.

drop,- wires are of two different types,1 and Each heddle-isformed with a threading aperture. 3: and an elongated slot at the end, the latter serving as a suspension opening: andi adapted to receivethe suspension or hanger bar The slots-of the-heddlesl are gllCllCltfiCl at 5 and the slots of the heddles The; upper ends of the slotsasswell as the apertures 3.coincide.in both sets or types of heddles, but the lower ends. of the slots 5 are nearer the aperturesB in the heddles l thanare the-lowenends of the slots 6 in the heddles 2:, thereby providing longer slots in the; heddles 11' than in. the heddles 2. The heddles 2. are: furthermore provided with the apertures? which are arranged between the aperturesil; and the slots 6. and which coincide. in part with. the lower ends of the slots 5 instheheddles 1 It therefore follows that. when-a1 number of. the heddles of both sets are arranged. in alinement, a substantially continuous aperturethrough the series is.- formed; by the. apertures] and the lower ends ofthe slots-5 as isshowninFig, 2.

The internalvariationin construction just described however, provides for. arranging the heddles in. series in alternating order, that is toisay, first. aheddle of one type and then aheddle. of. the; other. type, and. so on, so that. due. to this. regnlar,.alternate variation. of. internal. form heddles; a. holding; portion: is. presented. by eachheddle which isuncovered by the preceding heddle, By thisimeans separating or releasing. devices may be: employed so that, when engaging; the holding portion of. the foremost heddle it. will hold. back all. succeeding heddles of the. series, but by being shifted, to the; holding: portionv of the next succeeding heddle; the first. heddle of the seriesiisa thereby released or separated while the remaining members of the. series. are still held. back or retaine The cooperation between the. structure of thedescribed forms of heddles and a typical form of mechanical. releasing device may be illustrated by the. action. of the releasing devices. shown in the drawings. The heddles being assembled, as indicated in igs. 5v and. 6,-they are initially retained in series by releasing hook. 8 formed at. one end of a releasing rod. 8", the latter extending between. successivev means of a/ retaining and.

through the continuous aperture referred to as formed in the series of heddles. The

heddles are su 3 )orted n 3011 a su oortin rod 9 which is one member of a two part telescopic shaft, the supporting rodbeing adapted to fit loosely within the apertures 3 with which the heddles of both sets are provided, and the rods 8* and 9 being arranged parallel to the suspension bar 4. a

The slots 5 and apertures 7 are so located with reference to the apertures 3 that the releasing rod 8 is permitted a free movement in the continuous aperture thereby provided. By reason of the arrangement and relation of the aperture 7 and the slots 5, however, the releasing hook 8, when eX- tending upwardly, is in a position to engage the holding portion of a heddle 2 directly above the aperture, but, when extending downwardly, is in a position to clear the aperture and engage the holding portion of the next adjacent heddle 1 directly below the slot 5. The result is that when the hook extendsupwardly, it retains the foremost heddle 2 together with'the series behind the vame, while releasing the preceding heddle 1 When turned downwardly, it frees or re- .eases the heddle 2, holding back the succeedng heddles l'together with the series behind he same. In other words, when the hook, vhich, by analogy, may be compared to the .iour hand of a clock, points totwelve, as

shown by Fig. 1, it is adapted to retain a heddle 2, but when it is turned to approximately siX oclock, it releases the heddle2, retaining the succeeding heddle 1. It is apparent, therefore, that, if the heddles are arranged alternately with regard to their structural variation and the releasing rod 8 with its hook 8 be extended through the substantially continuous aperture thereby formed, continued rotation of the releasing hook in one and the same direction will effect therelease of the heddles one by one at half rotation of the hook, while retaining all the remaining heddles of the series.

Any suitable mechanism may be provided for turning the releasing shaft, or the same nay be turned by hand, as desired, and any lesired means may also be employed for maintaining the heddles compacted against the releasing hook. These and other mechanical featuresrelating to the releasing devices form no material part of the present invention which concerns the arrangement or construction of the heddles themselves.

The separation of the successive heddles as described may be utilized for any desired purpose. The heddle after being released, for example, may be conveyed to a position where it is adapated to be acted upon by threading devices. In the illustrated embodiment of the invention, the released heddle is adapted to be fed by gravity or other means along the supporting rod 9 and to be engaged by the turning and facing screw 10 carried by the other member 11 of the telescopic shaft 9 and thereby faced for the threading operation which may be either automatic or non-automatic. As these devices form no part of the present invention,

they need not be further described in detail.

.is such that by the method of assembling them or arranging them in series, as, for eX- ample, by a reversal of the 13031131011 of successive heddles, a holding portion is presented by each heddle uncovered by an aperture in the preceding heddle.

Ido not herein claim broadly any alternate variation in arrangement or construction of the heddles whether internal or ex: ternal, claims to that generic feature being embodied in my copending application Serial No. 824, 2 19 filed llLlarch 12,1914.

While for illustrative purposes I have herein shown and described one specific embodiment of the invention,- it is to be under-- stood that the same is not limited to the de tails of form or arrangement herein shown, but that extensive deviations may be made therefrom without departing from the spirit thereof.
