Application led April 22, 1910. SerialNo. 557,070.

To all whom t may concern.' Be it known that I, Hno'ron LE DOUX, a

citizen of the United States, residing at ric looms shown anddescribed in U. S." Let` ters Patent, No. 747,587-, in which needles orvwires, over which the loops of the fabric are formed, extend in the direction of the length of the fabric, and the pile loops also extend in the direct-ion of the length of the fabric. l

Ithas been found in practice in the class of looms referred to, in which the pile wires or needle/s loosely extend through the, reed toward the breast plate, to have the pillloops formed thereon, that the outer pile wires and the edges of the woven fabric do not extend in a Straight line from the reed. Aile fabric becomes narrower than it shoul and does not extend the full width of the reed, .and the edges of the goods, after the pile loops have been cut, show an uneven appearance.

The object of my invention is to provide a spreader, which is adapted to keepthe edges of the fabric exactly .in line with the dents of the reed and with the pile wires.

My improved spreader preferably consists of a roll or rolls preferably rotatable,

and suitably supported and extending inv the direction of the width of the fabric. The roll or. rolls may have corrugations therein, or Separate disks or plates thereon, which are adapted to engage the fabric between the rows ofthe longitudinally exfabric, said loops having .tending pile.. loops, near the edges of the ing thereimand press the fabric down upon the breast beam plate, over which the Woven fabric-passes, and upon which it is Supported, to hold the fabricl stretched transversely, and maintain a uniform width thereof.

` My invention' consists in certain novel fea-- tures of 'construction of my improved spreader, as will be hereinafter fully cle- -scribed; I have onlyshown inthe drawin over the free end 10 the wires extendy tached fpart of a pile fabric loom of the class referre to,.with my improvements attached thereto, sufficient to enable those skilled in the art to understand the construction and operation thereof. v

`Referring to the drawings :#-Figure 1 :is a longitudinal sectional view showing the upper part of the lay, .the reed, and pile wire with the pile loops formedlthereou,

and my improved spreadercombined there' with. Fig.,2 is a-plan view of lsome ofthe parts shown in Fig. 1, looking` in the direction of arrow a, same figure. Fig. 3 is a sec tion, on line 3, 3, Fig. 1, looking in the direction of arrow b, sa1ne`}fi"ure,and, Fig. -t corresponds to Fig. 3i, but shows a modified construction 'of the spreader when .the same is used on wide looms.

ln the accompanying drawings, 1 is' the breast beamwhich is attached to the loom side, not shown, 2 is -the breast beam plate` attached to the breast lbeam 1, and over which the Woven pilefabric 3 passes and 1s supported upon, 4 ist-he lay, Awhich has va rocking' motion communicated theretoV in the ordinary way. y

5 is the reed, supported on the lay 4,1and 6 the hand rail on the top of the reed.

8 -is' a cross bar, which has secured thereto the lower end of the upwardly extending blades 9, to which the inner ends of the pile wires or-needl'esfl() are attached. The pile wiresor needles 10 in this instance extend.

through the reed 5, between the dents thereof, toward the breast beam .plate 2, to have of the'pile Warp 3 formed of said needles 10. Allfof the above mentioned parts lmay be of the usual and Well known constructhe pile lloops 3 tion in looms ofthe class `referred to, and

are particularly shown Vand described Patent, No. 747,587, above referred to.

Iwill now describe my improvements.

`.The breast beam plate 2 has mounted thereon, in this instance at each end thereof,

a sta-nd 11 adapted to receive, in suitable slots, the ends. of a transversel \1 extending rod 12, which maybe made tubular at its inner )ort-ion, as shown at 12" in Fig.- 1. On eaicih end of the rod'12 is in this instance loosely mounted a spreader or roll 13. i The roll 13l has secured thereon' in this instance circula ,tes13-, lneferably'v the reed, and adapted to enter the woven fabric between the longitudinal rows of pile loops thereon, said loops having the wires extend ing therein.

A helically coiled expansion spring 14 encircles the rod 12 on the inner side of the roll 13, and bears at one end against the inner end of-the roll 13, and at its other end against a washer 15, which` is secured in position on the rod 12 in this instance by a Cotter pin 16, see Figs. 2 and 3. Holes 12 in the rod 12, see F ig. 2, allow the cotter pin 16 to be changed, according to the de' sired tension on the spring 14. The spring 14 is adapted to yieldingly hold the spreader or roll '13 outwardly or toward the edge of the fabric. The outer end of the roll 13 bears against a collar 17, which'is adjustably secured on the rod 12, in this instance by a bolt 17.

The rod 12 h'as'in this instance a vertically extending opening through its end, through which in this instance loosely extends an upright bolt 18. .The bolt 18 has a hand wheel 18 thereon, the hub of which extends loosely through an opening in a side extension 11' on the stand 11. The lower end ofthe bolt 18 is in this instance threaded and -screwed into the base or foot 11b on thestand 11. A helically coiled expansion' spring 19 encircles the bolt 18, and bears at one end against the lower end ofthe hub on the hand wheel 18', and at its other end against the upper side of the transverse rod 12. The compression of the spring 19, by turning the bolt 18,'through the hand wheel 18', increases the downward pressure on the rod 12, and on the roll 13, and causes the disks orplates 13 thereon, to enter the fabric, between the longitudinal rows of loops; said fabric being supported upon thebreast beam plate 2, and press the fabric down upon the plate 12./ The spring 14 in this instance acts to spread or move outwardly, thro-ugh the engagement of the disks or plates 13 with the fabric, the fabric at itsv edges, and hold the edges of the fabric in a straight line.

In Fig. 4 is shown a modified construction. Instead of the transverse rod 12 eX- tending the full width of the fabric, I may use in wide looms a short rod 21, see Fig. 4, at each side of the loom, and at each edge of the fabric. The short rod 21, shown in Fig. 4, is in this instance adjustably held in a stand 11 by the set nuts 21 threaded end of said rod. The head-Ql on the inner end of the rod21, forms a bearing for the inner end of the expansion spring 14, to hold the spreader or roll 13 in its outward position.

It will be understood that the details of construction of my improvements may be varied 1f desired.
