UNITED JOSEPH SLADDIN, or LAWRENCE, MASSACHUSETTS.

IMPROVEMENT IN LCOlVl-l-l-ARNESSr Specilication forming part of Letters Patent No. 164,277, dated June 22, 1875; application tiled May 20, 1875.

' the several Letters Patent issued to me, dated August 4, 1868, No. 80,774, and reissued and' dated August 8, 1871, in two divisions, A and B, Nos. 4,509 and 4,510, dated November 28, 1871, No. 121,258, and dated March 3,1875, Nos. 148,252 and 148,253.

The invention particularly relates to suoli loom-harness as are made from four lengths ot' yarn, as, for instance, such as shownand described in the Letters Patent above referred to, dated March 3, 1875, Nos. 148,252 and 148,253; and the present improved harness is composed ol'1 yarns, from which heddle-eyes are made as in Letters Patent just above referred to, and all the yarns leading from and on one side ot' the heddle-eyes are secured to one and the same rig-band by knitting or sewing the 'same thereto' in any ot' the well-known modes or otherwise, and all the yarns leading from and on the other and leese side of the heddle-eyes are secured by the yarns leading from one series of eyes to one rig-band, and the yarns leading from the other series of eyes to another and distinct rig-band, and to their respective rig-bands they are knit or sewed in any of the wellknown modes or otherwise properly fastened. Thus is produced a harness having three distinct rig-bands, one on one side and two on the other and leese side of its eyes, so that if then a separate shaft be used for each rigband, and the two shafts at the side ofthe harness, having two rig-bands, be held apart in any suitable manner, the eyes of the harness can and will be so separated as to secure a closer and freer movement of the harnesseyes through the warpthreads, as the harness rises and lowers, and without interference therewith; and, furthermore, this invention consists in the combination, with a harness of the form and construction above described, of novel-constructed blocks for holding the two shafts at the leese side of the harness, separated fromeach other, and for the suspension of the harness in a loom, all as hereinafter particularly described.

In the accompanying plate of drawings, Figure lis a plan View, showing tbe two shafts at the leese side of my improved harness, and the improved blocks separating the same Fig. 2 is a sectional view at line x or from top to bottom of my improved harness and the shafts; and Fig. 3 is a horizontal4 section along line y y, Fig. 2. Y

In the drawings, a a and b b represent the yarns or twines, from which heddle-eyes are formed, all substantially as in Letters Patent hereiubefore referred to. rEhe yarns b at one side, A, of the harness are secured by knitting, sewing, or otherwise to a common rigband, j', and the two yarns a at the other side, B, ot' the harness, which side is the leese side thereof, are secured by knitting, sewing, or otherwise the one yarn to a rig-band, g, and the other yarn to a rig-band, h. Thus the harness is made, and into it at its rig-bands are inserted shafts C, G2, and G3, one shaft at each rig-band, in the usual manner, with har` ness having only a single rig-band at each and both of its sides, and these two shafts, G2 and C, at the leese side of the rigband are held apart by the insertion of blocks D between them, which blocks are secured in such position by fastening them to the two shafts with Screws l l, or other suitable means, that pass through the shoulders 'm of the blocks, and thence screw into the top edge of each shaft C2 Cf. (See Fig. 2 more particularly.) The blocks 1)' are provided with eyes a, by which to suspend the harness in a loom.

vMy improved harness herein described possesses many features ot' advantage, and among them the following: Thatit can work the better and the freer through the warp, because by holding apart the two shafts at one side of the harness the heddleeyes can and will be opened or separated from each other, and thus made to occupy the position of four distinct rows, (see Figs. 2 and 3,) whereas with only one rig-band in place of the two, as aforesaid, the heddleeyes would be very. close to each other, and substantially inv only two rows;

that stronger and larger twine or yarn can be used, thus increasing the durability of the harness and greatly economizing in the ex pense of harness to manufacturers.

In the manufacture of the improved loomharness herein described, I prefer to use coutinuous lengths of yarns, as particularly described in my said Letters Patent, dated March 3, 1874:; but I do not intend to limit myself to the same, as separate lengths of yarn may be used for each heddle-eye formed. Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. A loom-harness, having its heddle-eyes made from lengths of yarn, and these yarns secured to three rigbands, of which rigbands one is at one side and two at the other side of- JOSEPH SLADDIN. Witnesses:
