To all whom it may concern:

, Be it known that I, Sumter; SEWALL. Jr., of Tewksbury, in the county of Middlesex and State of Massachusetts, have invented a new. and useful Improvement in Heddles forLooms,

of which tlie'following is a. specification.

The object of the present invention is to provide a heddle for looms which, while occupying but small space laterally, will present a hroadbearing-surface to the warp-threads, and

at the seine time befree from angles and corners of a nature liable to catch -,or pinch the threads, and thus to weaken -or break them. The broader the bearing-surface the larger the "number of fibers over which thestrain' will be distributed, au'd thus the less the danger of thethreads being thereby broken. The invention also relates toa peculiar construction and mode of mounting theheddle, 2o whereby, with the same number of-hed'dles in a given space, they will have greater play. or -i'reedom of motion among themselves;'or, if required, the number of-heddles' to a. givel'i 'spuce'can be increased withoutimpairing'their :5 freedom of motion. Y 1

I The invention is fully illustrated ingithe accompanying drawings. v 1 I In these drawings Figures 1 and 2 are, respectively, a front and side view of the im- 0 proved heddle, and Fig. 3 is a perspective view of the middle and end portions of the same on. au'enlarghd scale. Figs. 4 9.11115. re-

spectively, are a front and side view of the middlepart ofa heddle in which the eye, in-

stead of being elongated, is circular. Fig. 6

is a modification of the eye shown in Figs. '1,

. 2, and 3, the modification consisting in cutting away a portion of the inner lips of the two members that form the eye. Fig. 7 is a perspective-A'iew, showing four ofxthe heddles mounted in their frame.

.This improved heddle is made from a; thin strip of metal, preferably steel. The eye is formed by slitting the blank at the proper point along the middle. longitudinal line, and

i by means of suitable diesbending the twosec tions of the divided blank into substantially ,therelat'ive forms shown in Figs. 1,, 2, 3, and

' I By 11 inspection of these figures it willbe n that bhth ends of one section of the diwidcdjblank are-bent outward from the genoral plane ot the metal strip in onedirection,

is bent in the reverse direction sufficiently to occupy a' position on the other side of ,the general plane of the strip, the corresponding parts of the other section of the divided blank the first part. By this construction the two sections will c'ross each other at two points,

whichyvill constitute the eye of the heddle. This eye may be made circular or elongated, as may be required by the nature of the work to which the heddle is to'be applied, the cirangle intowhich the thread can: draw and be cahght or pinched. This circumstance, as well as the extent of bearing-surface which is 'assured by this construction, becomes a mat' ter of importance in line work or where the warp-threads are of weak texture.

.As-theheddles' can be'made of very thin metal a" large number can be arranged iu a given space, the construction being such that the configuration .of each. corresponds with gether closely. the cawgen when the heddle's' are inade straight t o'ughout,'0 r are so constructed'that the thread-eye lies in the plane of the supporting'rods; but a Fig. 2 is preferable. As hereshown, the midcontains the thread-eye, and where, therefbre,

"tie to one side of the plane in which the beddle-rods are Situated, this fact being fully illustrated in Fig. 2, in which the parts forming the thread-eye. are shown as lying wholly on while the intermediate portion of such section and their intermediate partspvill form a-loop' cular-form. being specially designed for weavconstruction substantially like that shown in dle part ofthe heddle, being the part whichthe crowding is liable to occur, is thrown alit mm so.

being bcnti-n directions opposite to those of sides of a plane perpendicular to the warpthreads, it results that there is no corner or that of its neighbors, so that they nest to-.
