HEDDLE.

Specification of Letters Patent.

Patented July 31, 1917.

Application filed November 27, 1915. Serial No. 63,772.

To all whom it may concern:

Be it known that I, WILLIAM PIOKARD, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Heddles, of which the, following is a specification.

This invention relates to a new and improved construction of heddle, and particularly to improvements in heddles of that kind designed to be used in carpet weaving looms, such as are employed for weaving Brussels or tapestry carpets and the like, wherein a plurality of warps of different materials are used and it is desirable that the surfaces of the heddles should be absolutely smooth or devoid of sharp angles, projections or surfaces liable to cut, tear or cause excessive wear upon the threads.

The primary object of the invention is to provide a construction of heddle, formed as usual of two rods or wires, brazed or soldered together and the parts of which are constructed and arranged to avoid the production of objectionable surfaces at the joints and to produce a heddle which has smooth or rounded surfaces at all points.

A further object of the invention is to provide a construction of heddle in which the parts of the heddle are not only united by the solder or brazing composition, but are also interlocked to a certain degree so as to increase the strength of the heddle at the joints, as well as the strength of the heddle as a whole.

A still further object of the invention is to provide a construction of heddle of the character described which admits of the production of smooth joints in a ready and convenient manner and at a cost not exceeding the cost of production of heddles of ordinary construction.

The invention consists of the features of construction, combination and arrangement of parts herein fully described and claimed, reference being had to the accompanying drawing in which Figure 1 is a side elevation of a rod or wire as preliminarily prepared for use in the production of my improved heddle.

Fig. 2 is a view showing the two wires or rods of which the heddle is to be formed arranged in juxtaposition prior to assemblage, parts of the wires being broken away.

Fig. 3 is a view similar to Fig. 2 but showing the inner ends of the wires joined or assembled preliminarily to the soldering or brazing operation.

Fig. 4 is a View showing the inner ends of the wires united to form the connecting joints and complete the manufacture of the heddle.

Fig. 5 is a plan view, on an enlarged scale, of the eye portion of the heddle, showing the brazing or soldering material in section and exaggerated in extent of projection to better indicate the formation of the joint.

Referring to the drawing, disclosing one mode of carrying my invention into practical effect, 1 designates a heddle constructed in accordance with my invention and comprising a pair of rods or wires 2 and 3 constructed and united at their inner ends, as hereinafter specified, to form the eye 4, and each of which members is bent at its outer end to form the usual hook or loop 5. The rods or members 2 and 3 are preferably made from smooth spring steel wire, of circular or other suitable form in cross section, but any kind or shape of material adapted for the purpose may be employed. The eye l is preferably of elliptical form, which lends itself admirably to the carrying out of the invention for the production of surfaces clevoid of objectionable projections, but this exact form of the eye is not absolutely essen tial, as any other form of eye adapted to perform the same function may be employed.

In carrying my invention intopractice for the manufacture of my improved heddle, a

rod or wire, such as a rod or wire 2, of proper length is used and initially or finally bent at one end to form the loop or hook 5, while the opposite or inner end of the Wire is first formed with a transverse out, notch or slit 6, at a suitable point adjacent to its extremity, and the portion of the wire between such slit and extremity then bent into segmental or semi-elliptical form, as shown at 7, along the weakened line formed by the slit, so as to spread the walls of the slit apart at an angle to each other and thus provide a substantially V-shaped notch or recess 8 in the wire at the point of intersectionof the body of the wire with the curved portion 7 said notch or recess lying substantially at an oblique angle to the axis of the wire. The free end or extremity of the portion 7 is at this or at any prior period then cut away at an angle, as shown at 9,

to produce a beveled surface and form a substantially V-shaped portion at the end of the wire which is of proper dimensions to fit snugly within the corresponding notch or recess 8 of another section of wire, such as the wire 3, formed in the same manner, it being understood that in the production of each heddle two wires of the identical construction set forth are produced tobe joined together to make the finished article. After the wire members2 and 3 are formed, their curved or opposite ends 7 are. brought in juxtaposition to each other, as shown in Fig. 2, and they are then brought together, as shown in Fig. 3, so that the curved portions 7 will lie opposite each other and collectively form the elliptical eye 4:, while the extremities 9 of the respective wires will lie at an angle to the axis of the wires, the

body portions of which will be coaxially disposed or in longitudinal alin'ement with each other, The V -shaped portion or tongue 9 of each wire will thus engage and snugly fit within the notch or recess 8 of the other wire, and thus lap the same at an angle, thus bringing the inner ends of the wire into connection so that they will be locked to a determined degree against separation or any other than lateral movement, each tongue lying wholly within the confines of the recessed portion which it engages. It will be observed by reference to Figs. 2, 3 and 5 of the drawings that by the provision of the V-shaped notches 8 and tongues 9 said tongues and notches present abutting faces which are at an angle to the axis of the heddle and produce maximum interlocking effect. The solder or brazing material 9 is then applied'at and about the points where the tongues engage the notches or recesses, so as to produce a pair of finished lap-joints 10 at the extremities of the eye, permanently joining or fastening the rods or wires 2 and 3 forming the handle in an absolutely firm and durable manner.

It will beobserved that by constructing and forming the eye in the described manner, an eye of preferably oval or other elongated form is produced whichis adapted for the free passage of the thread without bind ing orrkinking, and that as the portions of the wires at the unions are bound or embedded in the joining material a firm connection at the joints is established. These joints or connections are rendered of great strength and durabilityby reason of the fact that the parts at the point of union form Y-portions or branches which are united so as to mutually reinforce each other against strain in any direction, while the interlocking engagement between the extremities of the wires absolutely hold the wires against any tendency to separation in a longitudinal direction and to a large extent also in a lat eral direction, the heddle being therefore of as great strength at the eye as at any other portion, and in many cases being of greater strength. Furthermore, the form of the joint lends itself admirably to the shaping of the soldering or brazing substance in substantially conical or other suitable form which is devoid of angles or irregular or sharp surfaces, and presents only smooth and curved surfaces over which the threads may travel in a free and easy manner and without liability of the same becoming cut, torn or raveled' Also by the production of lap-joints, in which the parts of the joint interfit at a lapping angle, wholly within the confines of their surfaces, the angular portions of the wires are Wholly concealed and covered or bound up in the binding medium, so that they can not become exposed so as to damage the threads. 7

It will thus be seen that my invention provides a heddlewhich is not only simple of construction and inexpensive of production, but which embodies the structural features or steps of manufacture necessary to produce an article having the desired qualifica' tions to an admirable degree, and whioh'is designed'to be employed with the highest efliciency for the finest grades of work. WVhile the structure and mode of manufacture set forth are preferred, it will, of course, be understood that changes within the scope of the invention as defined in the appended claims may be made without departing from the spirit of the invention.
