THREAD PARTER FDR WEFT=REPLENSHING LOOMS SPECIFICATIQN forming part of Lettersliatent No. 667,661, dated IEebruary 5, 1901.
A1131. :ation filed May 24, 1900. Serial No. 17,798. (No model.)
To a, who/7t fir? 7121.07 concern:
Be it known that I, JONAS NORTHROP, a citizen of the United States, residing at Hope dale, in the county of Worcester and State of Massachusetts, have invented an Improvement in lhread-Parters for Weft-Replenishing Looms, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.
This invention has for its object the prod uction of novel thread cutting or parting means for looms and more particularly applicable to looms provided with automatic filling-supplying mechanism, whereby the leugth of thread extending from the selvage of the cloth to the filling-carrier ejected upon change of filling can be parted.
Ihave provided novel means for making the threadparter laterally adjustable to accommodate cloth of difierent widths, it being desirable, manifestly, to sever the thread adjacent the selvage.
In the practical embodiment of my invention herein shown the thread-parter is mounted on a shuttle-feeler, and when the shuttle is properly positioned the shuttle-feeler brings the thread-parter into operative position, the actuation of the latter to part the thread being effected as the lay heats up.
Various novel features of myinvention will be hereinafter described, and particularly pointed out in the following claims.
Figure 1 is a cross-sectional view of a portion of a loom provided with automatic filling-supplying mechanism with one embodiment of my presentinvention applied thereto. Fig. 2 is an enlarged detail in plan of a portion of the lay, the shnttle-feeler, and threadparter, the lay being supposed to be moving forward to complete its stroke; and Fig. 3 is an enlarged detail, in side elevation, of the thread-parter, the jaws being shown closed.
Referring to Fig. 1, the frame A, breastbeam A the lay A the self-threading shuttle S, the hopper or feeder F and transferrer f, mounted on the stud f, forming a part of the automatic filling-supplying mechanism, and the shaft d, adapted to be rocked by or through. the action of the feeler (not shown) upon exhaustion of the filling in the shuttle to a predetermined extent, are and may be all substantially as in United States Patent No. 641,792, dated January 23, 1900, the end f of the transferrer having mounted upon it a headed rocker-stud 0%, provided with an attached arm m on which is mounted a notched d 0g m provided with a lateral lug m,a bunter C on the lay engaging the dog when moved into position prior to a change of filling. As in said patent, a bracket A is mounted on the frame and has pivoted thereon at 5 an upturned rearwardly-bent arm y, forming a shuttle'feeler, said shuttle-feeler having a lateral stud or roll 6, normally engaged by a detent-finger d fast 011 the rock-shaft cl, maintained in the position shown in Fig. 1 by the strong spring S a branch y, (see dotted lines, Fig. 1,) rigidly secured to the shuttle-feeler, engaging the lug m on the dog m the parts herein described operating as set forth in the patent referred to.
As best shown in Fig. 2, the shuttle-feelery has bolted securely thereto, as at 12, a lateral arm a, extended inward toward the cloth, said arm having a bolt 13 extended therethrough to enter a longitudinal slot b (see dotted lines, Fig. 2) in a long arm I), rigidly secured to the thread-parter, a nut 14 on the bolt 13 holding the two arms together in adjusted position.
The thread-parter is shown as comprising a strong fixed jaw 19, secured to the arm I) and extended toward the lay and having fulcrumed thereon at b the movable jaw b a spring 5 Fig. 2, coiled around the fulcrumstud b and secured at one end thereto, normally maintaining the jaws open, the other width of the latter, space being left between I00 the thread-parte'r and the selvage for the temple T. Now when the shuttle-feeler is moved toward the lay it can complete its movement if the shuttle is properly boxed, as in Fig. 2, and the thread-parter is moved into operative position, the thread of filling, extending from the selvage to the shuttle, passing between the jaws b b. If the shuttle is not properly boxed, the thread-parter will not be moved into operative position, and consequently operation of the same will be prevented.
Any suitably-located projection on the lay can be arranged to strike the finger b as the lay heats up to close the jaws and part the thread, and such projection may be a portion of the reed, enough dents being removed to prevent interference with the jaws; or I may insert an upright projection or bar 71 Figs. 1 and 2, at theend of the reed, between the lay and the reed-cap R, the projection being located in either event back of the shuttlerace, as will be manifest. The lateral extension of the finger b permits considerable lateral adjustment of the thread-patter for any given position of the actuating device 17 and it will be noted that the finger b is located above the point at which the thread is engaged and parted by the jaws, thus obviating any interference with the thread. After the thread-parter has been actuated the spring .9 opens the jaws in readiness for the next operation.
The construction shown herein may be changed or modified without departing from the spirit and scope of my invention.
Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In a loom, a shuttle adapted to carry a supply of filling, a shuttle-feeler, having a laterally-extended arm, and a thread-parter adjustably mounted on said arm.
2. In a loom, a shuttle adapted to carry a supply of filling, a shuttle-feeler, a threadparter, and a longitudinally-extensible connection between it and the feeler and extended laterally from the latter.
3. In a loom provided with filling-supplying mechanism, the lay, a shuttle adapted to carry a supply of filling, a shuttle-feeler operatively connected with said mechanism, a threadparter movable with the shuttle-feeler, to part the thread of the filling-carrier to be ejected upon change of filling, said thread-parter including a finger locatedabove the plane of the cloth, and a device on the lay to engage the finger and actuate the thread-parter.
4:. In a loom, the lay, a shuttle-feeler having a lateral arm, a thread-parter comprising normally open parting-jaws and a finger to close them, adjustable means to connect said thread-parter with the arm on the shuttlefeeler, and a device on the lay to engage the finger and effect closing of the jaws.
5. In a loom, a shuttle-feeler, a laterallyadj ustable thread-parter carried thereby including a movable jaw having an upturned extension, and means to engage said extension above the thread to be parted, to actuate the jaw.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
JONAS NORTI-IROP.
