UNITED STATES PATENT GEEIeE CARL L. F. PFEFFERKORN AND WILHELM AST, OF lVANCHESTER, N. H.
IMPROVEMENT IN Loom-SHUTTLS.
Speciiication forming part of Letters Patent No. 143,927, dated October 2l, 1873; application filed August 20, 1873.
To all whom 'it may concern! Be it known that we, CARL l). FERDINAND PEEEEEEKOEN and WILHELM AUsT, both of Manchester, in the coimty of Hillsborough and State of. New Hampshire, have invented a new and useful Improvement in Shuttles for Looms 5 and we do hereby declare the following to be a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the saine, reference being had to the accompanying drawing forining part of this speciiicatioimin which drawnig- Figure l represents a longitudinal vertical section of our invention. Fig. 2 is a plan or top view of the same.
Similar letters indicate corresponding parts.
This invention relates to that class of loomshuttles which are provided with instruments for cutting the weft-thread, said cutting-in struinent being operated by a stop-lever when an obstruction occurs in the shed.
Our invention consistsinforming the cuttinginstruinent oi' two jaws, which are pivoted together, one of said jaws being operated upon by a spring and formed with an extension having a curved bearing, upon which operates a pivoted stop-lever, as hereinafter more fully set forth.
In the drawing, the letter A designates a shuttle, of the ordinary form and construction of iiy-shuttles, provided with a quill, B, and an eye, E. C C represent tension-rollers, the lower one of which is stationary, while the upper one presses down upon the lower by its inherent gravity. The thread is passed through between the two rollers, and
it is kept at aunii'orm tension, and it is drawn off evenly from the cop, so that the operation of the loom is not interrupted until the weftthread gives out or is cut O.
0n the inside of our shuttle is secured a case, F, which is provided with a passage forming a continuation of ,the eye E, and in said case is placed a cutting-instrument, G, which is made in the forni of shears, and which is so situated that the weft-thread in its passage to the eye of the shuttle has to lpass through between the jaws of the shears, as seen in Fig. 1 of the drawing.
This cutting-instrument is composed of a movable and a fixed jaw, c c', the movable jaw e being provided with an extension, 11
having a curved bearing or projection, upon which traverses the pivoted stop-lever b for holding the movable jaw out of contact with the iiXed jaw c until the stop-lever is turned and the jaw forced down by the action of a spring bearing directly upon the back of the movable jaw, so that when the stop-lever is thrown in the position shown the movable jaw is forced out against the 'action of the spring, whereby the weft-thread can pass the eye E without obstruction.
If the shuttle is thrown through the shed and the stop-lever b meets with no obstruction, the cutting-instrument remains in the position shown in Fig. l, and the weft-thread is thrown into the warp, the saine as it is from an ordinary shuttle. But if there are loops in the warp, or if any other irregularsaine ease with which he now attends to four looms 5 and, furthermore, our shuttle is so constructed that it is not liable to get out of order, and that it can be used for a long time without requiring any repairs.
What we clailn as new, and desire to secure by Letters Patent, is
rlhe movable jaw c', having the extension d formed with a curved bearing-surface, in combination with the fixed jaw c, the spring a, and pivoted lever I), all constructed and arranged and confined within the metal case F, as herein shown and described.
