WIRE-RETAINING DEVICE FOR LO OMS FOR WEAVING PILE FABRlCS.

SPECIFICATION forming part of Letters Patent No. 529,615, dated November 20, 1894.

' I Application filedMarch 5,1894- Serial No.502,430. (N model.)

To 60% whom it may concern: I

Be it known that I, HARRY HARDWICK, a

' citizen of the United States. residing in Philadelphia, Pennsylvania, have in ventedcertain Improvements in Wire-Retaining Devices for Looms for Weaving Pile Fabrics, of which the following is a specification.

The object of my invention is to provide a loom for weaving pile fabrics with means whereby the production of uniform pile is insured, and this object I attain in the manner hereinafter set forth and claimed, reference being had to the accompanying drawings, in wl1ich- Figure 1, is a longitudinal sectional diagram representing sufficient of a loom to illustrate my invention. Fig. 2, is a plan view showing the selvages of the cloth and the lateral limits of the warp by dotted lines, and illustrating but one of the pile wires; and Fig. 3, is a perspective view of the attatchnient forming the subject of my invention.

In modern looms for weaving Brussels and Irvilton carpets and like pile fabrics, the pile wires are frequently in the form of thin blades which are intended to stand upright in the row of pile loops and thus govern the height of said loops as well as the width of the same. It will be evident, therefore, that if the pile wire does not maintain the upright position from selvage to selvage of the fabric the uniformity of the pile will be seriously af-' fected and in practice this is often found to be the case, the strain of the pile warp upon the central portion of the pile wire causing the twisting of the same so'that the central portion is bent forward and downward and thus fails to properly determine the height and position of the pile loops in this portion of the fabric. In order to overcome this objection I use one or more retainers located between the selvages. of the fabric and adapted to engage with the upper edge of the pile wire and hold the samein the proper ver-,

tical position.

In Figs. 1 and 2 I have shown one of these retainers located midway of the fabric, said retainer belng represented at A while B represents the breast beam of the loom, D the reed, w the pile fabric which is being woven, and y the pile supporting wires which are successively introduced in the usual manner in advance of the beating up .point and are successively withdrawn after the fabric has advanced to the proper extent.

The retainer A has a hook a for engaging with the last inserted pile wire and projecting forwardly beyond this hook is a finger b preferably of such length that it will pass through one of the spaces of the reed when the latter has been retracted to itsfull extent, so that said reed will serve to hold the free end of the retainer in properlateral position at alltimes. The retainer has an arched shank d possessing such elasticitythat the tongue I) and hook at of the retainer can yield vertically in order to permit of the passage of a pile wire beneath the tongueand to a position in advance of the hook in beating up, the hook then springing into engagement with the pile wire so as to mantain the same in the desired upright position.

The outer end of the retainer A is slotted as shown at f forthe reception of a retaining bolt g which is screwed into a bar F mounted upon the breast beam beyond the selvages of the fabric and supported at such height that the fabric can pass freely beneath the same. Having thus described my invention, I claim and desire to secure by Letters Patent- 1. A pile loom, having a pile wire retainer secured to a support above the fabric which is being woven, and located between the op-.

posite selvages of r the same so as to engage the body of the last inserted pile wire to retain the same in upright position, substaning woven, and apile wire retainer carried by said bar and occupyinga positionbetween the opposite selvages of the fabric, said retainer being hooked to engage with the last inserted pile wire in order to hold the same to hold the same in upright position, substan- 10 in nprightposition,substantially as specified. tiaiiy as specified.
