DEVICE FOR SUPPORTING LOOM-HARNESS.

SPECIFICATION forming' part of Letters Patent No. 268,136, dated November 28, 1882. e

Application filed May 19, 1882. (No model.)

o all ywhom. it may concern Be it known that I, JOSEPH SLADDIN, of Lawrence, Massachusetts, haveinvented a new and useful Device for Supporting Loom-Harnesses, of which the following is a specification,'when taken in connection with the accompanying drawings, of which- Figures l, 2, and 3 are partial views of sufficient of a harness to exhibit the manner in which harnesses have been supported hitherto, while Figs. 4, 5, and 6 represent so much of a harness as will exhibit the application thereto of my present improvement; and Figs. 7, S, and 9 represent details of the construction of my device. Y

Fig. l shows a condition which the heddleeyes (marked a a) of a loom-harness are caused to assume in relation te each other by the device usually employed for connecting the lharnessesrwith the cords by which they are suspended and moved. A represents the upper one of the two harness-shafts, around which the twines t pass. Along the top of this shaft is seen, at b, the backing-cord, to which the twines are tied or knotted. At c, screwed into the top of the harness-shaft, midway between its two sides, is shown the hook or loop to which A the heddle-cord is fastened. The lower shaft dle-eyes in the twines attached to the backing- I cords at that point out of their proper relation to the other eyes and to the harnessshafts, as shown at Fig. 1. This deflection of the backing-cords from a right line, and consequent displacement of the heddle-eyes from their correct position, is an evil, to remedy which several contrivances have already been devised. For instance, the heddle-shafts have been notched for the reception of the twines, whose eyes would otherwise be deflected from their true position; and, again, the shank of the old form of hook or loop (shown at Figs. l, 2, and 3) has been made with an offset or recess to receive the backing-cord. But I remedy this evil by providing a device to which the heddle or supporting and moving cords are attached, which, when applied to the harnessshaft,forms an arch or loop across the surface of the shaft, through which the backing-cord passes ina straight line. along the middle of the edge of the shaft and directly under or above the heddle-cords, accordingly as the device is applied to an upper or a lower harness-shaft. Thus the supporting or moving cords and the backing-cords are both kept in the vertical plane which passes through the middle of the harness-shafts, and the heddle-eyes are all free to take their proper position between the shafts. The essential feature of this con trivance is, that it leaves a free passage for the backingcord at the middle ofthe outer edge or side of the harness-shaft, and at the same time supports the harness in the vertical plane of the backingcords. The device which I have made and applied to secure these conditions is shown in detail at Figs. 7, 8, and 9, and it is shown as applied to the harness at Figs. 4, 5, and 6. In these igures, as far as applicable, the same letters are used which are used in Figs. 1, 2, and 3 to designate like parts. The said new device is marked d. The device is made of a wire bent into a loop at the outer end to receive the supporting or moving cord, and into another loop or clasp atthe inner end to go around the harness-shaft, leaving a space between the outer edge or surface of the shaft and the clasp, as seen at e in Fig. 6, through which the backingcord may pass without obstruction, as seen at Figs. 4 and 5. Grooves should be formed in the sides of the harnessshafts to receive the wire, so that it shall not interfere with the placing` ofthe leaves of heddles side by side and shall offer no obstruction to their upward and downward movements. The wire is sprung into these grooves after the shafts have been placed in the twines, and one end is turned at the neck at right angles with the rest, so as to form a lock, to prevent the device from springing away from the sides of the shaft. This device allows the backing-A IOO cord to run in a straight line alon,f ,t the harness-shaft, as seen at Fig. 5, and brings all the heddIe-eyes into the same line, as seen at Fig. 4. The improved device shown in the drawings is represented with a double eye for receiving the supporting-cord; but upon an inspection ot Figs. 8 and 9 it is obvious that the left-hand upper loop there shown is unnecessary, it only being requisite that the free end ofthe wire of the lower loop shall extend far enough beyond the neck ofthe device to be caught under the other end ot' the wire, turned as above described.

The essential part of the device consists of a wire bent into two loops to resemble the tigure 8, with the ends ot' the wire meeting and locking at the neck of the ligure, and with one loop enlarged and distorted, so that when applied to the heddle-shat't it will closely embrace said shaft upon three sides and leave a space the backingcord, substantially as described.
