LOOM SHUTTLE.
Patented Nov. 22,1881.
INVENTOR ATTORNEYS.
UNITED STATES PATENT OFFICE.
CHARLES T. PRATT, OF NEW HARTFORD, NEW YORK.
LOOM-SHUTTLE.
SPECIFICATION forming part of Letters Patent No. 249,988, dated November 22, 1881.
Application filed October 4, 1880. (Model) To all whom tt may concern:
Be it known that I, CHARLES T. PRATT, of New Hartford, in the county of Oneida and State of New York, have invented a new and useful Improvement in Loom-Shuttles, ofwhich the following is a specification.
The object of my invention is to prevent blemishes from being woven in cotton cloth. Such blemishes are caused by a thread of the warp breaking and becoming snarled in the shed, and thereby preventing some of the warp-threads from crossing when the shed is changed.
Nearly all cotton-looms have a stop-motion applied in connection with the filling to stop the loom when the filling breaks or runs out. My devices are for use in connection with such stop-motion to insure the stoppage of the loom when a blemish is being woven.
My invention consists in the peculiar construction and arrangement of the parts, as hereinafter more fully set forth in the claims.
In the accompanying drawings, Figure l is a plan view of one end of a shuttle containing the weft-breakin g devices. Fig. 2 is a partial section of the same on line was of Fig. 1. Fig. 3 is a perspective view of the improved devices detached from the shuttle, with the fingers in a horizontal position; and Fig. 4 shows a side view of the same, with the finger-piece B in a raised position; also, an edge view of piece B.
Similar letters of reference indicate corresponding parts.
A is an ordinary shuttle-body, and a is the spindle carrying the bobbin, from which the filling-thread runs to the delivery-tube b in the side of the shuttle. in a recess at the end of the shuttle is fixed a plate, 0, the end of which extends into the bobbin-recess and is bent downward beneath the end of spindle a. This end of plate 0 is also formed with side tongues, 61 d, the object of which is to prevent the fillin g, when slack,fro1n getting beneath the plate 0. On the plate 0 is fixed a guide-eye, e, for the filling.
B is the finger-piece, attached by a screwor pin to a lug, n, at one side of plate 0, so as to swingin either direction lengthwise of the shuttle. The piece B, as shown most clearly in Fig. 4, has two projecting fingers or ends, f, which are formed with right-angled projections f f and the piece is also formed with a projecting portion, g, at its mid-length. The object of the portion 9 is to balance the ends f and prevent the piece B from being jarred out of position when not otherwise held. The functions of the projections f f are to intercept the filling-thread. The slack of said filling-thread will be caught on one or the other ot these projections and be cut or broken thereby whenever the finger-piece B is thrown down to a horizontal position by the tangled threads in the shed. Upon the side of pieceB is a pin, h, which engages with a notch in a spring, '5, that is attached to plate 0, so that the piece will be held with the endsf vertical, as shown in Fig. 4. The fingers f are bent inward, so that their projections f f come in the centerline of the shuttle, or nearly so, in order to insure their engagement with the filling-thread, as hereinafter specified.
In operation, the piece B is placed with the fingers vertical, and is held by the spring. The upper finger,f, in this position projects above the shuttle. If there be any tangled threads in the shed, they extend across the path of the shuttle and will come in contact with the projecting finger and turn the piece B, so that the fingers are turned to the horizontal position. In this latter position the filling is caught by either one or the other of the projections f f and broken, and the usual stop-motion that is fitted in connection with the filling is brought into operation. The same effect takes place when the shuttle is moving in either direction, the piece B being turned in .either direction accordingly.
With these devices the usual stop-motion is utilized to stop the loom and prevent blemishes in the goods by broken and tangled warpthreads.
The upper curved part, m, of finger f will prevent the fin ger from going too far in either direction, and it will be understood that the device may be arranged right or left handed, according to the shuttle.
Having thus described my invention, I claim as new and desire to secure by Letters Patent The plate 0, formed with side tongues, 61 d, and provided with eye 6 and lug n, pivoted piece B, formed with fingers f, and holdingspring 6, in combination with a shuttle-body, substantially as and for the purpose herein set forth.
