LO OM FOR WEAVING .VALANCES.

SPECIFICATION forming part of Letters Patent No. 545,607, dated September 3, 1895.

Application filed February 29, I892.

To all whom it may concern.-

Be it known that I,]IsAAo E. PALMER, of Middletown, in the count-y'of Middlesex and State of Connecticut, have invented a new and useful Improvement in Looms for Weaving Valances, of which the following is a specification.

My invention relates to an improvement in looms in which provision is made for advancing the warp more rapidly along the center than at the edge.

The object is to provide for weaving afabric which, when its selvage edge is held in a right line, will hang in folds or present the appearance of having been gathered.

A practical embodiment of my invention is represented in the accompanying drawings, in which- Figure 1 is a top plan view of a portion of a loom embodying my improvements. Fig. 2 is a view of the same in vertical section from front toward the rear. Fig. 3 is a view of the cloth-roll in detail. Fig. 4 is a view in detail showing means for holding the fabric level immediately in front of the lay, and Fig. 5 is a view in detail showing a slightlymodified form of breast-beam.

The particular fabric which I have indi- .Gated herein as being woven, iswoven closely at its opposite edges and more loosely toward the center, the warps being entirely omitted at the center, so that by cutting the fabric longitudinally along its center line each half will form, when its selvage edge is held straight, a body portion hanging in folds and provided with a fringe consisting of the unwoven weft-threads.

The main frame of the loom is represented by A and the lay by B. These parts may be of any well-known or approved construction.

The breast-beam is denoted as a whole by O, and is of a general semicylindrical form, with its fiat side toward the lay, and its opposite ends are tapered down to the point where it is intended that the edges of the fabric shall engage therewith. I have shown the breast-beam as formed of two sections 0, arranged to slide toward and away from each other along a fixed support a and adapted to Serial No. 423|19 (N0 modeli) To hold the fabric level and prevent any tendency it may have to narrow between the lay and the breast-beam, I provide a roller F, which maybe journaled in armsf, secured to the ends of the frame A and extend horizontally across the fabric on a level with the upper surface of the most contracted portion of the breast-beam. In the place of the roller F the breast-beam might be flattened along its upper surface, as shown at C, Fig. 5. As the tapered cloth-roll is rotated step by step to take up the warp, the enlarged central portion will advance the warp more rapidly than the contracted end portions, and the result will be that the edge of the fabricwill. be woven more closely than the central portion. When the edge is straightened andthe fabric along the center allowed to hang, the tendency of the central portion will be to dispose itself in the form of folds and present the appearance of having been gathered. The fabric so formed may be employed as drapery for the sides of hammocks or wherever a f ulled or gathered drapery is desired.

What I claim is- 1. In a loom, a take-up roll comprising adj ustable sections having tapered ends and means for securing the sections in adjusted position toward and away from one another longitudinally of the roll, substantially as set forth.

2. The combination with the lay, and the cloth-roll having tapered ends, of a breast beam having its ends tapered, substantially as set forth.

7 be locked in the desired adjustment by set- 3. The combination with the lay, and the tending across the loom intermediate of the cloth roll having tapered ends, of the breast lay and breast beam to hold the fabric level,

beam comprising adjustable sections having substantially as set forth. [0

tapered ends, substantially as set forth. ISAAC E. PALMER.

4. The combination with the lay, and the Witnesses: cloth roll having tapered ends, of the breast JOHN C. LADD,

beam having tapered ends and a guide ex- WM. W. VAN DEURSEN.
