JACOB SENNEFF, OF PHILADELPHIA, PENNSYLVANIA..
wEAvERs HEDDLE,
Specification of Letters Patent No.`11,335,.d ated July 18, 1854.
` To all whom t may concern.'
Be it known that I, JAcoB SENNEFF, of the city and .county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Weavers Heddles or Harness; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making part of this specification.
Figure 1 is a front view of a heddle composed of two strands placed'parallel together. Fig. 2 is a front view of a similar heddle on an enlarged scale. Fig. 3 represents a heddle of two strands twisted together below the eye and divided above, after the manner of the ordinary knotted heddle. Fig. 4 is a section of the heddle represented in Figs. 1 and 2. Fig. 5 is a horizontal section of the core for dividing the threads at the eye. Fig. 6 is a front elevation of a heddle composed of two threads twisted above and below the eye to form a single strand.
Similar letters in the figures refer to corresponding parts. A
The nature of this invention and improvement consists in fastening the strands or .threads or wires of the heddle together, to
form the eye, by means of metallic clasps, cast or otherwise secured around and between the same, in such a manner as to form a substitute for the cumbersome knots heretofore made to connect them together, and to cause the heddles to occupy less space, and better adapt them for line work, present less friction to the threads of the warp, and be more durable and easily made, than if the eye was formed by the usual tye knots.
When the heddles are composed of two parallel strands A, as represented in Figs. 1, 2, and 4, they are wound upon the shafts in the proper relation to each other to form a lease, or in the usual or most approved` manner, with the `strands of each, side by side, and the strands are separated to form the parts allotted to form the eyes, by means of a core or tongue B, curved on its sides and upper and lower edges, and brought to a point, sowas to enable the strands to be easily divided and moved over it, to its enlarged part, where it is made of the proper curvature on its upper and lower edges, to slightly open or separate the strands within the molds, to allow the molten metal to flow between them, to give a corresponding concavity to the parts of the cast clasps C, next l the edges of the core or tongue, forming the ends of the. eye, on which the main frictio-n of the threads of the warp within the eyes, takes place.
The molds in which the clasps C are cast, are arranged above and below the core or tongue B, and are curved Von their sides, so as to resemble in cross section the sides of a parabola, and are simply large enough to admit the strands and leave spaces between and around them, to contain the required quantity of metal to hold them firmly together. They are made in two parts, and are brought together to embrace the strands, somewhat after the manner of the molds elnployed to form the metallic eyes of my improved heddles patented on the 13th day of January and 20th day 'of July 1852, and their parts next the eyes are so formed as to enable the strands to be separated at the ends of the eye by the core or tongue, to`
allow the molten metal to flow in between them, and around the edges of the core or tongue, to form the smooth concave ends of the eyes. By employing this mode of securing the strands together to form the eyes, they are not taken out of a straight line between theshafts, except so far as the thickness of the threads of the warp, at the points where the molten lead flows between them, to form the ends of the eye, and are not consequently subjected to the friction and wear fromthe threads of the warp between the heddles, and in the eyes, rubbing against the parts of the strands forming the sides of the knots, and ends of the eyes, of the usual knotted heddles-the principal friction and wear, being, on the smooth curved sides, and concave ends, of the metallic clasps.
Instead of forming the heddles of two strands, placed parallel as `above described, they may be composed of two threads twist ed together above and below the eye, to form a single strand A1, and opened or separated to form the eye, and secured together by the clasps C at the ends of the same, in a similar manner to the separation and securing of the two strands of the heddle de scribed above, as represented in Fig. 6, or the threads may be twisted below or above the eye of the heddle, into a single strand A2, and divided above or below the upper metallic clasp, so as to form two strands A3, similar to the heddle now in use.
What I claim as my invention and desire ends between the strands or threads, where to secure by Letters Patent, is they form the ends of the eyes, in the man- 10 Forming the eye of the heddle, by casting ner and for the purpose herein set forth. or otherwise securino around and between '5 the strands or threadns composing the same, JACOB SENNEFF' metallic clasps in lieu of the cumbersome Witnesses: knots heretofore employed, curved on their NORMAN GOFF,
sides and made concave and smooth on their C. BRAZER.
