Looms for WeavingDouble Pile Fabrics, of

which the following is a full, clear, and exact description, referencebeing had to the accompanying drawings, forming a part of this specification. I a

My invention relates'to improvements in looms for weaving double pile fabrics comprising two spaced backing webs or cloths connected by pile threads which are woven to extend across the space between the two cloths and to be afterward cut centrally between the two cloths to form independent pile fabrics.

Looms for weaving fabrics of this character employ spacing devices called pilegages around which the double fabric is woven and which serve to properly space the two backing webs or cloths'to preserve a '1 uniform gage or-length for the pile forming portions of the pile threads extending between the cloths.

The object of my invention is to provide a pile-gage of novel, simple and efficient construction, whereof the portion which gages and controls the distance between the two backing webs and the'arm which holds the pile-gage in place, may be formed integral with each other in a single piece and of such form that a proper spacing of the two backing webs may be effected without injury to thefabric.

A further object of my invention is to provide a novel pilegage actuating heddle of such construction that it will'not injure 40 the warp threads and of such construction that it may be readily applied to or removed from the horizontal rods or bars of a heddle frame.

To these ends my invented device consists of the elements and the combinations of them hereinafter fully described and claimed.

In the accompanying drawings, illustrating my invention. Figure 1, is a side view of my improved pile-gage and heddle therefor. Fig. 2, is an edge view of thepilegage and heddle. Fig. 8, is a vertical sect on through a portion of a loom for weaving double pile fabrics, showing a'portion" of the weaving mechanism and my improved pilegage and heddle included therein.

Referr1ng to the drawings, my improved pile-gage comprises a flat arm 2 having one end thereof tapered between upper and lower converging faces 3 and 4:, respectively, for purposes hereinafter explained;

My improved heddle for operating the p le-gage 2 comprises a pair of vertically disposed wires 5 between the central portlons of which the end of the arm 2 having the hole 6 therein is located. The wires 5 are twisted together, at 7, within the opening 6, at 8, directly below the arm 2, and, at 9, directly above the arm 2, thereby pivotally connecting the central portions of the wires 5 to the arm 2 in a mannerto permit the wires 5' to be moved vertically to raise and lower the connected end of'the arm 2 while the free end of the arm2 remains substantially in the same position. The adjacent upper ends and the adjacent lower ends of the wires 5 are twisted together and form eyes between the twisted portions 11 and 12 at each end of the heddle for the reception of the spaced horizontal heddlesupporting bars or rods'18 of a heddle frame 1 1. It will be readily understood that by untwisting the portions 12 at the two ends of the heddle, the heddle may be readily removed from the bars 13 of the heddle frame 14, without removing the bars or other heddles, to insert a new heddle, should a heddle or its pile-gage be broken or otherwise rendered unfit for use.

When in use'in a loom for weaving double pile fabric, the pile gage 2 and its heddle are associated with the weaving mechanism as illustrated in Fig. 3, wherein 15 designates the upper portion of the lay, 16 the warp threads, 17 the raising and lowering devices for the warp threads to form the sheds through which the shuttle or shuttles are projected during the weaving operation,

18 the upper web or backing cloth, 19 the lower web or backing cloth, 20 the pile forming threads woven into and extending between the upper and lower cloths l8 and 19, 21 the cutting knife for the pile threads,

and 22 and 23 the rollers which support the cloths 18 and 19 around which they pass as theyv are produced and the pile threads are severed. The'backing webs or cloths 18 and '19 are formed at the points 24 and 25, re-

spectively, and pass therefrom in the direction of the arrows as rapidly as formed. The general constructionand operation of the parts of the weaving mechanism for the manipulation of the threads in weaving the fabric are common andwell known and no detailed description or illustration thereof is deemed necessary herein. I v p A number of the pile gages as illustrated in F ig. 3 are employed sideby side. in the loom and the heddle of each gage 2' is carried by the rods 13 .of the frame 14, sothat when the frame 14 israised andlowered theentire set of pile gages 2 will be raised and lowered to positions above and below the shuttle path, as the. different sheds are formedduring the weaving operation. Any

of the well known devices employed in looms to'raise and lower heddle framesmay be employed toraise andlower the frame 14.

r The warp threads 16 extend betweenthe heddles whichparry the pile gages 2 and, during the weaving of the two backing webs or cloths 1 and 19, in the usual manner;

' the warp threads andheddles are raised and V lowered withv respect to eachother; and, duringthis operation, my'im'provedheddle pile gages, Serving to maintain the two back-' ing webs or cloths 18 and 19 the proper distance apart during the weaving of the entire double fabric;'an d,' as rapidly as the fabric is formed, and passes in the direction of. a 1 the arrows, the fabric passes from the free.

ends of the pile-gages 2. The free ends of the pile gages. are supported by and between the two cloths 18 and 19. The point of connection between each arm 2 and its heddle is raised and lowered in a direct vertical line; and, therefore, as the arms 2 are raised and lowered, the free ends thereof are projected on into the space between the cloths 18 and 19 and withdrawn to the positions shown, as the arms 'move toward and from the horizontal central position between the uppermost and lowermost positions. When the arms 2 are in the lowermost position, as shown by full lines in Fig. "3,.the'upper face 3 is substantially parallel to the upper'cloth 18, and when the arms 2 are in the uppermost position as shown by dotted lines in Fig. 3, the loweriface-a is substantially parallel to-the lowerclo'th l9. T-his' tapered end of the arm 2 formed between-the converging faces ,3 and 4 1s an important feature of my invention as it enables-me to maintain the proper I vertical dimensionsof the pile gage 2 at the fell of the cloth, at all times without having the 5 free-ends of the pile gages 2 engage and prohorizontal plane, when the arms 2 are low.-

. ered, and without having the free ends of the pile gages 2 engage and project the lower cloth 19 below its normal horizontal plane, when the arms 2 are lowered, and I am thus enabled to prevent injury to the cloth and uneven weaving; Further, the

tapered'end of the pile gage enables it to work its. way from between the cloths l8 and 19 as the arms 2 are raised and lowered,

'ject the upper cloth 1'8 above its normal thus obviating the necessity of the employment of meansto move the arms 2 longitudi- V nally. V I
