J. E. DOLBBR. LOOM SHUTTLE THREADER.
No. 576,343. Patented Feb. 2,- 1897.
UNITED STATES PATENT. OFFICE.
. JOHN E. DOLBER, OF MANCHESTER, NE\V HAMPSHIRE.
LOOM-SHUTTLE THREADER.
SPECIFICATION forming part of Letters Patent No. 576,343, dated February 2, 1897.
Application filed June 13, 1896.
To all whom it may concern.-
Be it known that I, JOHN E. DOLBER, a citizen of the United States, residing at Manchester, in the county of Hillsborough and State of New Hampshire, have invented certain new and useful Improvements in Loom- Shuttle Threaders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
The object of the present invention is to provide a simple instrument for quickly threading the shuttles of looms.
Various hooks have been heretofore used,
I but they are apt to fail to operate unless the yarn happens to be placed in the position most likely to be caught by the hook.
My invention consists in a novel clamping,
device which when placed in the eye of a loom-shuttle below the loose end of the loose yarn is adapted to receive the yarn by reason of a spring-actuated feedingarm, said feeding-arm forcing the yarn into said clamp, where the yarn will remain after the feedingarm is withdrawn, as fully set forth in the following specification and claims, and clearly illustrated in the drawings accompanying and forming a part of the same, of which- Figure 1 is a detailed perspective view of my improved threader. Fig. 2 is a similar View showing my improved device as when in operative position in the eye of a loomshut-tle, Fig. 3 being a cross-section view of the yarn-clamp.
Similar letters denote corresponding parts.
Various constructions may be adopted, that which I show comprising a cylindrical piece of metal A, having attached at one end a divided or bifurcated arm B and at the opposite end a spring-arm O, which may be formed of wire and coiled, as at c, and bentsubstantially in the shape shown for the purpose of passing over the side of a loom-shuttle, as in Fig. 2. The free end of said spring-arm is somewhat flattened, and its extreme tip is provided with a V-groove c, so'that it may more Serial No. 595,414. (No model.)
readily engage the loose yarn in the shuttle when pressed toward the yarn-clamp or bifurcated arm B.
The purpose of the spring-arm C is to feed the yarn into the yarn-clamp B, and in order to more perfectly effect this a suitable guide must be provided for the spring-actuated arm 0, and such a guide maybe composed of a wire loop D, fastened rigidlyto the cylindrical piece A as near as possible to the yarn-clamp B, and to facilitate the entrance of the feed ing-arm 0 between the two sections 1) b of the bifurcated arm or yarn-clamp B the upper adjacent surfaces of said sections b b may be cut away or grooved, as at Z), at the point of contact of said feeding-arm O.
In forming the feeding-arm of round wire a small plate-piece a may be rigidly attached, so as to provide a better resting-place for the finger of an operator when the device is in use.
In the drawings the feeding-arm is shown in its normal position, and after passing the yarn-clamp B through the eye 6 of shuttle E the feed-arm C may be pressed toward the yarn-clamp, when by means of its V-groove c the loose yarn in'that end of the shuttle which it is desired to pass through its eye will be carried between the sections 1) b of the yarn-clamp B, where itwill remain after the feed arm has been withdrawn from said yarnclamp, which is accomplished by removing ones thumb or finger from the plate 0 of said feed-arm, and the device may then be drawn from the eye of the shuttle, bringing the yarn with it, a slight jerk being sufiicient to separate the yarn from the yarn-clamp.
F is a section of a bobbin, and G represents the yarn.
' Having described my improved device, what I claim is l 1. In a loom-shuttle threader, a spring-actuated yarn-clamp adapted to enter the eye of a shuttle, and a spring-actuated feedingarrn adapted to feed the yarn into said clamp.
2. In a loom-shuttle threader, a bifurcated arm formed of spring metal, and a spring-actuated arm having its free end flattened and with a V-groove at its extreme end, all sub- 10 adapted to enter the bifurcated arm, substanstantially for the purpose set forth. tially for the purpose set forth.
