JACQUARD HEDDLE AND METHOD OF MAKING TI-lE SAME.
SPECIFICATION forming part of Letters Patent No. 244,982, dated August 2, 1881.
. Application filed May 20, 1881. (No model.)
To all whom it may concern Be it known that 1, JOHN H. CROWELL, of the city and county of Providence and State of Rhode Island, have invented a new and useful Improvement in Jacquard Heddles and in the Method of Making the Same; and I do.
hereby declare that thefollowin g specification, taken in connection with the accompanying drawings, forming a part of the same, is a full, clear, and exact description thereof.
. My invention, relates to heddles for use upon Jacquard looms; and my improvement consists in a heddle composed of one continuous piece of twine returned upon itself to form the two legs of a heddle, with one legtmade longer than the other to allow'of tying upon one side, near one end of the heddle, and having the heddleeye formed by claspin g the parallel halves of the heddle together with metal bands, which determine the'length of said eye.
My improvement also relates to the method of producing such heddles economically, which consists in continuously returning a single twine upon itself in parallel folds to make a continuous series oflegs of heddles, securing the ends of such folds to back hands by binding-threads, attaching metal clasps to each pair of heddle-legs to form eyes, varnishing and dressing the whole series of heddles, cutting the whole series in a line parallel with one of the back bands, so as to leave one leg of each heddle longer than the other, and-finally withdrawing the back bands to separate the series into single heddles, as described. 7
As usually constructed heretofore Jacquard heddles have been composed of a metal eyepiece to which two distinct leg portions have been attached by passing the twines composing such leg portions through perforations in the ends of the metal eye-piece and tying the respective ends of each leg portion together. A
heddle thus composed has two knots, which is objectionable, and the leg portions not being immovably secured to the eye-piece theseknots are liable to obstruct the operation of the heddle when in use. In my improved heddle there is but one knot, which is located in the most desirable position, and the parallel halves of the heddle being secured to each other by metal clasps such knot cannot change its position during the use of the heddle.
I have illustrated in Figure 1 of the drawings the manner in which the continuous twine is returned upon itself in parallel folds to form a series of uncut heddles. Fig. 2 shows such series of heddles securedto back bands by binding-threads, so that the heddles may be economically dressed. Fig. 3 represents the same mounted upon shafts in such a manner that the series of heddles can be cut into individual heddles with different lengths of legs. Fig. 4
shows a single heddle when removed from the back bands; and Fig. 5 represents the same with its ends tied, forming a complete Jacquard heddle.
A machine for making a series of heddles from a continuous twine by returning the same upon itself in parallel folds and securing the ends of such folds to back bands is fully described in another application for Letters Patent which I have prepared, the same having been filed May 20,1881, and machinery for placing the metal bands upon the heddles, is fully described in other Letters Patent heretofore granted to me, June 30, 1874, No.152,465.
Although my improved heddles may be constructed individually by hand, yet I prefer to form them in the manner set forth-that is, to form the heddles in series by returning a. continuous twine, A, upon itself and securin g the ends of the folds to back bands, B B, by suitable binding-threads, b b, in order that the se ries may be economically varnished or dressed. After being placed upon shafts (J, as shown in Fig. 3, and dressed, the series of heddles is divided into individual heddles, a, by a single out upon the line 00 m. The binding-threads b b are then cut-'as, for instance, on the lines Y Y Y Y-and the series will be separated into individual heddles, a, one leg, Z, of each of which will be longer than its fellow, l, as shown in Fig. 4'. The ends of the heddle are then tied, as shown in Fig. 5, and the heddle is complete for use upon a Jacquard loom.
By an examination of Figs. 1, 3, and 4, it will be readily seen how, by cutting the series on the line or w, one leg, 1, of a heddle, a, will be longer than its fellow, I. As shown in Fig.
2 assess 1, the loops at the left hand of the series belong to distinct heddles, respectively, while each loop at the right hand forms a part of two adjacent heddles. When the series is cut on the 5 line as m, Fig. 3, therefore, a heddle such as shown in Fig. 4 is the result.
What I claim as my invention, and desire to secure by Letters Patent, is-
1. The improved heddle for weaving in a {o Jacquard loom, consisting of a single twine re turned upon itself and having one leg longer than the other for tying, as shown, and having the eye formed by two metal clasps uniting the two legs, substantially as described. 1 5 2. The improvement in the method of manu: facturing Jacquard heddles, which consists in JOHN H. OROWELLv Witnesses W. H. THURSTON, I. KNIGHT.
