Aplimion med rebruryzalacfi. sum1 No. 194.708.

Be it known that I, WILLIAM PEAnsALL, a subject of the King of England, residing at Worcester, in the county of Worcester and. State of Massachusetts, have invented a new and useful Needle-Loom, of which the followyin is a specification. v

lnvention relates to' that class of looms in which the' filling or weft threads are needle.

`carried across the loom by\a long bar or The es ecial objects of this invention are lto provi e .a-'simple, eflicient, and reliable needle-motion for looms and to combine the needle-motion with simple? and efficient tene sion and -take-u devices, together with' a simple and ellicient selvage-motion, which will finish one edge of the fabric without "'.crimping or puck'ering. l To these ends thls Inventlon consists ofthe needle-loomand of the combinations of parts therein, ashereinafter described, and more particularly pointed out in the claims at the end of this specification. l

In the accompanying two sheets of drawings, Figure 1 1s a front view oflsufficient parts of a loom to illustrate the connections for operating the needle. Fig. 2 is a detail view of the take-up arm. Fig. 3 is a 'detail plan view of the carriage for operating the needle. Fig. 4 is la detail view of the skewer or pin which holds a loop of the filling-thread form of loom having been especially designedA the can'iage'lhwhichlcanies a needle N,

while the needle Ais being retracted. Fig. 5 is 'a plan view of 4suflicient parts of the loom to illustrate the selvage motion and Figs. 6 to 8,

inclusive, are dia rammatic views illustrat-- ing differentpositions 'of the parts in' the formation of the selvage. j

The needle-loom covered by 4this application for patent is designed for weaving thechain or -body portion of a pile fabric, this for use in connection with the tufti'nglmechanism shown; described, and claimed in a separate Vapplic-ation for patent which `hasbeen executed by me on even date herewith.

Referrin .-to, the accompanying drawings for ay detai description of the construction, as shown in Fig. 1 at one side ofthe loom isa framework comprising side'frames A, connected by anupper tie-beam B anda lower tie-beam C. vCarried by the framework isla Sli'deway 10, movably mounted on which is i which moves back and forth'through a guide Gto carry a loop of filling-thread across the loom.' T

e/needle-carriage 11 is connected by a link 12 to an operating-lever L, which is' 'connected to be oscillated b alink 13 from a crank-arm 14 carried'by t e shaft 15. By means of this construction the needle will be moved back andforth in a horizontal line across the loom. The filling or weft thread f may be drawn from a coil or other suitable source of supply S and passes through a tension-clamp From the tension-clam T'the thread passes around a small guide-ro ler 16,

carried by the take-up arm 17, and through a guide4 or eye in the upper end of the take-up arm 17. y As shown most clearly in Fig. 2,' the take-up arm 17 is normally moved hack bya spring to draw back the surplus length o filling-thread which is carried across vthe loom to form a loop in weaving the selvage at the opposite ,side of the fabric. The take-up arm 17 is guided near its upper -end by suit-` able curved guides 18. From the thread guide or eye at the upper end of the take-u arm the thread asses through a feeler controlling any o the ordinary weft'stop-motions, and thence passes throu h an eye or guide near the point ofthe needle.

' The selvage-motion at the opposite side of .the loom is mostjclearly illustrated in the second sheet of drawings. .As shown in Fig.

5, 19 designates a. bracket extending from l the framework of the loom, and carried b the bracket 19 is a curved racewa f 20, whic supportsa shuttle 21. i The shutt e 21 is provided at its rear \end with a projection or vpoint 22 for engaging the loop of thread which is carried across the loom and while/it is held in place by the needle N. The shuttle is vibrated back and forth lin its curved br arc shaped path by vmeans of the shuttle guide or for 23, which is operated by a link 24. Coperating'with the shuttlev and needle is a skewer or pin 25, which is mounted in a guide 26 and receives the loo of thread to revent the tension of the ta c -up arm an draftv of the needle on its return stroke from puckering or straining the selvage edge of the fabric. The skewer or pin 25 as most clearlyillustrated in Fig. 4, is pivoted at its rear end to a lever 27. The-lever 27 is moved forward by'a spring 29 yand is moved back by ..acam28'. 1

The operation of the parts in forming a,

roo

IOS.

selvage according to thi s invention is most clearly illustrated in Figs. 6 to 8, inclusive. As shown in l ig. 6, the point 22 of the shuttle 21 iirst passes through the loop of fillingthread while the same is held in place bythe needle N. Simultaneously with the passage of the shuttle through this loop the needle N commences its return .stroke and the skewer or pin 25 is moved forward through the loop, as shown in Fig. 7. passed completely through the loop, as shown in Fig. 8, the take-up arm 17 yand the return draft of the needle N will draw the loop tight around the skewer or pin 25 and the skewer or pin 25 will support the loop of filling-thread and properly guide the saine into place, when the fabric is beaten up by a Vvibrating lay in the ordinary manner.

When a needle-loom as thus constructed is employed for weaving the chain of a tufted or pile fabric, the successively-formed piles may beheld back out of the way by the supporting-wire W, (shown in Figs. 5 to S, inclusiveg) but it is to be understood that the supportingwire W and the connections for operating the same form no part of the subject-matter claimed in this application for patent, as I have specifically claimed these features in my companion application for patent before referred to.

I am aware that numerous changes may be made in practicing this invention by those who are skilled in the art without depart-ing from the scope thereof as expressed in the,

claims. I do not wish, therefore, to be limited to the construction I have herein shown and described; but

What I do claim, and desire to secure by Letters Patent ofthe United States, is

1. In a needle-loom, the combination of the weft-needle, means cooperating therewith to form a selvage, a take-up mechanism for pulling back the surplus thread carried across by the weft-needle, and means mounted on the loom-frame and movable parallel with the warp for preventing the tension of When the shuttle has the take-up'mechanism from acting on the selvage.

2. In a needle-loom, the lcombination of a weft-needle, means cooperating therewith to form a selvage, a take-up mechanism for drawing back surplus thread carried across by the weft-needle, a skewer or pin mounted in the loom-frame and movable parallel with the warp, and means for operating said skewer to engage the weft-thread and prevent the tension of the take-up mechanism from acting on the selvage. Y.

3. In a needle-100111, the combination of the weft-needle, means coperating therewith to form a selvage, a take-up mechanism for pulling back surplus thread carried across by the weft-needle, a skewer or pin mounted in the loom-frame and movable transversely with respect'to the weft-needle, a spring for moving the skewer forwardl to engage a loop of weft-thread to prevent the take-up mechanism acting on the selvage. and a cani for moving the skewer back out of the Way for the next succeeding pick.

4. In a needle-100111, the combination of a weft-needle, a shuttle, a curved or arc-shaped runway for the shuttle, a fork pivoted upon a vertical axis and operating the shuttle to cooperate with the weft-needle to form a selvage, a tension-clamp through which the weft-thread is drawn, a swinging springpressed arm forming a take-up mechanism for drawing back surplus thread carried over by the weft-needle, al skewer or pin movable transversely with respect to the weft-needle, and a cam for operating the skewer to engage the loop of weft-thread to prevent the tension of the swinging spring-pressed arm from acting upon the edge of the fabric.

In testimony whereof I have hereunto set my hand in the presence of two subscribing.r

witnesses.
