To all 1li/71 om, t may foncer/i le it known that. l, PAUL Gmane, a eitizen oit the Republic of France, residing at Lyon, `in the Republic of France, have in* rented a new and useful Velvet or Carpet Loom, oi whieh the following is n Specification.

,The longitudinal pile-wires hitherto used in velvet or earpet looms were. bodies inclependent ot the healde in the heddles.

My invention relatesl to improvements in sueh looms. whereh)7 various advanti'iges are obtained.

' (lne imprortanent eonsiats in a special he'tldle Ytor the longitudinal pileavires, which heddle preferably comprises wire healds.

Another improvement eonsists in so eonneeting one longitrulinal pile-wire at the inner end/with every heald in the special heddle, that the pile-wire can he vertically adjusted, after the heddle has been loosened, and secured Ain any position by merely tightening' the heddle.

A third 'ixntn'orement Consists in rendering one part of the pile-wire adjoiningl the wire heald wholly or mostly pliable similar to a thread. so that the rapid vertical motion of the heddle is transi'nitted to the outer end ot the pile-wire merely by shoeks.

l will now proceed to desrrihe my invention with ret'erenee to the au'eompanying dra wings, in whieh- Figure l is a vertieal longitudinal see lion throlurh a pnrt of the velvet or enrpet loom and dianrammatieallr shows one loir gritudinal pilewire in Combination with the special heddle. Fig. .2 is an elevation on an enlarged seale. of the inner end ol' this pilewire and the middle part of the wire healcl o11 the special heddle, Fie. 2l is an elevation on an enlarged seale ot a modified long ritie dinal pilewire in eonihination with its wire heald, interuredtate parts heinglomitted.

Similar el iraeters et' referonee refer to similar parts throughout the stireral views.

ln Fig. l u aud o are the threads o'lAv the igrmuutwarp wound. o5'l` i'roin the heam l, they ilu-fads passing; the .mails at and t# of the healds rf and A tlei'iotes a beam 'for the pile-warp f whose threads passy thrfmgh the mails f1 in the healtl f2.

I are the wel'ts ot the grountl-ifahrie, l the ordinary wette or wires, the naps formed ot-the pilem'arii `f. For the. salie of clearness the 'pile-warp'f, the pile-leaf f2 and the naps are indicated by dotted lines, so as to better distinguish them from the other thm-ads and healds.

I provide a special heddle with heddles E l and eonneet eaeh of its healds with a longitudinal pile-wire G 1l, whoseI inner part (lr (l1 is slightly inclined and is inode pliable ynimilar to a thread, while the outer part (Si1 ll is made horizontal, that is parallel with the fabric, and less pliable. This pile directing member consists of a three-armed part. or heddle, having the arm E, the arm F, and the arm G-I1 of peculiar torniation. The threads oit' both the ground-warp a b and the, pile-warp f pass between the healds E F of the special heddle and through corresponding spaees of the usual reell 'not shown) and each longitudinal pile-wire ir H passes through a :space of suoli reed.

'lhe outer part. (i ll of eaeh longitudinal pile-wire may eonsist ol! two .euperposed wires f', and a vertical thin strip c of sheet metal soldered to and between them, whih` the inner part (l (il may trousist of the two wiresI o d alone, that is of a single wire doubled at the inner end G, as more clearly `shown in Fior. 2. lflaeh healdof the special leal' or heddle. E F may consist of two purallel wires lf/ g twisted together as at g2 (13, so as to `form a loop providing a space g* between the wires g g1. in which space the. two wires n engage from opposite sides, as is elearlr shown in` Fig. 2. Then the two wires fr (Z will he damped between the two wires g ,71, in ease the leal' or heddle is tightened, so that in this manner the bowed end G of the wirel n n. will he maintained .in its position relatively to the two wires g [/1 during); the vertical reelornent-ing,r motion ol" the special leal F. F. For altering the position of the bowed end (l it is only necessary to loosen and again tighten the leal.

The longitudinal pile wire G H- is made so thin as to enable them lo freely play in the spaces of the ,guiding reed ot shown) eren if the latter it: made narrow, so that the. pile-wiresdo not disturb the formation of a shed not| the motion of the shuttle. In eertain spares of the reed the threadsr of both the groundwnrp and the pile-warp inereup and down beneath the parts G Gl of the loiuritndinal through the said spare.

-During every upward motion of the speeial leaf or heddle lll F the inner parts G G1 of the longitudinal pile-wire connected therewith also raise the outer parts G H pilel wires passi` zg.

Iieu

- ing' transmitted to the outer end H by the has beenL loosened, andf'secured in any posiy tical direction.

gitudinal,.pile-wire has a hole 3, in which .,th'e'two wires g, g1 of the heald engage from Warp, so that the pilefwarp f in Figs. l. and

. ing -over single longitudinal pile-wire or and thereby raise the ordinary wets or wires t1, the rapid upward motion of the leaf beeife'ct of shocks similar vto a transverse wave line ,of sound'oscillation. At the lowest position of the special leaf or heddle the wefts t1 and consequently also the naps s are quite loose and the looni'can be'so arranged, that at this moment both the wefts t1 and the l:naps s are with the ground-fabric fed forward, so that the longitudinal pile-wires G H are-left behind and are not drawn in by the fabric.

' The construction of the longitudinal pile wire described above with reference to. Figs.4 l and Q, may be modified in that the pilewire l, la may be made wholly of thin sheet metal, it being astrip with rounded edges.- This strip 4, la is made wider at the ends than in the intermediate part, as is clearly shown' aty Fig. 3. The inner end of this lonopposite sides as shown. Then in a similar "manner 4to Fig. 2 the inner endGr can be easily vertically shifted, after the leaf E F Vti'on by merely tightening this leaf...

l he vertical'adjustment' of the inner end G 'of'v the longitudinal pile-wire of either construction described along the loop g2 [/3 of the heald renders it possible to form the naps' from thc weft instead of from the 2 can be omitted. The wefts t1 being then woven into the ground-fabric will by passover groups of longitudinal pile-wires form loops, that is the napsa The wefts t1 ot' course serve no longe'i in an auxiliary capacity but form the pile itself. l

The new'device' described above presents the advantage, that no mailsand no special fastening devices independent of the healds are required for thelongitudinal pile-wires. Furthermore the device presents the advanta e, that the inner ends of the longitudinal pi e-wires can be easily adjusted in the ver- The longitudinal pile Wires may be varied without departing from the spirit of my invention.. The inner part G G1 may be ivotally connected with the puter part G1 H, theessential point being, j that the rapid vertical motion of the special leat' E F' can be transmited through the inner, part G G1 to the outer end H solely through i the eect of shocks. l

Leccese I claim:

1.A device for -looms scribed, including a pile-directing member anda heddle, a member of said heddle comprising spaced lelements adapted to receive there between said pile-directing member, for vertical adjustment. .A

2. A device for looms of the type described including a pile-directing member, and a harnessv or heddle, a member of said harness comprising spaced elements adapted to receive there between said pile-directing member, opposed portions of said pile-directing member being passed from opposite sides of said harness-member elements, in applying said pile-directing member to the latter.-

, 3. A device for looms of the type described includiug a pile-directing member, and a heddle, a member of said heddle comprising spaced elements, said pile-directing member embracing a continuous wire bent to form parallel longitudinal portions, said portions` being passed between said elements,

upon opposite sides thereof, respectively, the resulting connecting arcuate portion between said longitudinal portions serving to prevent casual withdrawal of said pile-di" recting member from said heddle member. A

4. A device for looms of thetype described, including a pile-directing member, a heddle, a member of said heddle comprising spaced elements adapted to receive there between said pile-directing members, each of said spaced elements being adjustahly connected with a pile-directing member to guard against the position thereof being aifcctedv by the drawing action of the yfabric lin the direction in which it is being PAUL GIRARD.
