CARL VGRWERK, OF LEUTESDGRF, GERMANY.

NEEDLE-LOOM.

L/.l/ all whom it may cof/warn:

Bo it lrnown that l, Gann VORWERK, a subject olf the German YEmpire, residing at lieutesdor'lf, in the vthine virovinecn Prussia, Germany, have invented certain new and useful linprtn/einents n Needle-Looms, et which the tollou'ing is a` specification. accoinwinied by drawings. l

My invention relates to that kind or' loonis in which the weft, or iilling thread is carried across the shed hy means ot :i pair et needles or bars coi'iperating troni the sides toward and away ilironi each other so that they nieet substantially in the middle ot the leoni. one needle pushing the weft thread .in the forni oi a loop vtroni one side to the iniddle. and the other needle drawing-out the loop of the wett thread ot the pushing needle 'troni the middle ot the leoni unto the other side.

The special objectr et' niy invention to in'iprove the ineans for properly guiding and presenting the weit thread to the Ytorked end oll the pushing needle, and to vimpro e also the means for properly releasing or slippingl the loop of wett thread troni the hooked end ot' the drawing needle. 'lhese nieans coin sistell hitherto in complicated combinations oli' moving levers and cliltclrdcvices.v which could not work satisfactorily. I

ln order to dispense with all defects and disadvantages, l provide means which consist, each ot a single part only und require no active movement.

'io these ends niy inventionl rousists of the parts and combination oi parts as hereinat'ter describe jl and nio-re particularly pointed out in the claiins at the end ot this'speciiioation and as illustrated in the accompanying two sheets of drawings, showing sul'li cient. parts of the needle-looin to enable the application of iny invention to be clearly understood.

Figure l is a top View ot.' the weftnguiding finger according to niy present invention. Fig. Q is a plan view of the under-side of the pushingaieedle head. Fig. 3 is a front view ot said wett-guiding linge and Fig. l is the corresponding side view. Fig. 5 is a top view ot' the wett-.loop releaser according to iny present invention. Fig. 6 is the corresponding ironty view and Fig. 7 is a. trent. view showing' soine parts of the leoni in section and some parts advanced to another position.

Application ed .Tune 2G, 1906.

Patented Apr. 5, i919.

Serial No. 323,415.

Referring to the drawings and in detail, i is the lay.

i are reeds.

C is the table, carrying the table comb D for supporting the fabric, E.

F are Warp threads.

G the wett thread.

ll is the pushing-needle, guided in the arin i and formed with a groove l (Fig. 3) in its head. rEhe upper side is provided with an aperture l and the under side with a slot M open at the end oli the needle so that the end forked.

N is the drawing-needle, guided in the arni i) and formed with a iiattened hook l at its head.

Q is the race for the selvage-shuttle R, whieh shuttle carries the selvage-thread S for interstitching the loop T Jrorined by the wett-thread G.

il is the swinging arin .tor moving the selvage-shuttle R, which arm is journaled by ineans of the bracket U1, U2, U3 upon the support V.

W is the loop holder for preventing the loop '.i` ot the weit-thread, by catching it, from being retracted farther than to the selvage after the loop being released from the needle-hook P and interst-itched by the selvage-thread.

Arms ,l and O are customarily secured to Sonie iiXed part of the machine.

l, Figs. l, 3 and 4C is the weft-guiding iinger according to iny present invention. lt is suitably toi-ined at the free end of a bent piece, liXed at the end of the. lay so that the finger is pointing toward the reeds on a line son'iewhat behind that line on which the pushing-needle when entering the shed crosses the front of the reeds. The point oi the finger is, however, bent seinewhat backward (Fig. l) and upward (Fig. 3) so that the weft thread, being led through the aperture L of the pushing-needle H, can slide over the finger in the advancing of the lay, but will be caught by the finger in the baekward-inovelnent of the lay (Figs. l, 3, l). Thereby the weft. thread is drawn toward the back ol the groove K so that, instead ot coming out at the trent of the needle, as shown by dotted lines (Gr) Figs. l and 4, the weft thread comes out at the briin 3 of the needle, that is, at the back of the groove V New, as the pushingneedle advances, the weft thread will slide at the brim 3 downward and forward until it reaches the slot M and drops into it, whose end will then push off the loop of the weft-thread from the linger l.

et, Figs. 5, G and 'l is t-he projection for slipping or throwing' off the loop T of the weft thread G from the hool; P of the drawing-needle N. Said projection consists most suitably of a screw-pin extending through the swinging arm U which operates the selvage shuttle downward to the level of the surface of the hoolr P. The positionof the projection 4e is such as to enable the projection to reach the upper branch of the loop T justwhen the selvage shuttle B is extending the loop T at its maximum (Fig. 7). After the loop T has been disengaged from the hoolt l), and the selvage shuttle has passed through the loop, the loop is retracted by the outward-movement of the pushing-needle H and caught and stopped at the selvage of the fabric by the point of the needle lV.

l am aware that changes may be made in the shape or arrangement of the means without departing from the scope of my invention. l do not wish therefore to be limited to the form and disposition illustrated and described; but A lllhat T do claim, and desire to secure by Letters Patentl of the United States,

l. A loom comprising in combination a lay, a drawing' needle, a pushing needle, and a weft guiding finger secured to the lay at the end where the pushing needle enters the shed, and comprising means adapted to engage the weft thread during return movement of the pusning needle, said means formed to permit the weft thread to slip from the weft guiding finger during the forward movement of said pushing needle.

9. )i loom comprising in combination a lay, a reed, a drawing needle, a pushing needle, and a weft guiding finger secured to the lay at that end where the pushing' needle enters the shed and comprising a projection pointing toward the reed and adapted to en gage the weft thread during return movement of the pushing needle, and to permit the weft thread to slip ott' from the weft guiding finger during forward movement of said pushing needle.

3. A loom comprising in combination a ,l lay, a drawing needle, a pushing needle, and z a weft guiding linger secured to the lay at the end where the pushing needle enters the shed, said pushing needle being grooved and having on one side an eye and on the other side a fork, said weft guiding finger arranged to engage the weft thread during the backward movement of said pushing needle and cause said thread'to slip into the fork of said needle.

4. A loom comprising in combination a lay, a drawing needle, a pushing needle, and a weft guiding finger secured to the lay at the end where the pushing needle enters the shed, and having a point projecting toward the position of the warp-threads and also projecting upward, and adapted to engage the weft thread during the withdrawal of said pushing needle, the back of said projecting portion of said linger being rounded to facilitate free passage of the weft thread during forward motion of the pushing needle.

A loom comprising in combination a lay, means for passing weft-thread through a warp shed, and a weft guiding linger comprising a projection curved upwardly and toward the position occupied by the warp threads in operation.

6. A loom comprising in combination a lay, a pushing needle, and a weft guiding linger, said finger comprising means adapted to engage the weftl thread carried by the needle during return movement of said needle, said finger and needle relatively formed and adapted so that during forward movement of the needle the weft thread slips of itself from said linger.

T. A loom comprising in combination a lay, a pushing needle having an eye, a groove. and a slot opposite the eye, and a weft. guiding finger having a projection curved upwardly and toward the position occupied by the warp threads in operation, whereby during forward movement of the needle the weftv thread slips from said finger.

ln testimony whereof I have signed this specification in the presence of two subscribing witnesses.
