BACK STANDARD FOR GKUZE-WEAVING LOOMS.

SBEGIFICATION formingpart of Letters Patent No. 249,470, dated November 15, 1881. Application filed August 31, 1881. (No model.)

To all whom it may concern:

Be it known that 1, JOHN LATUS, of Birmingham, in the county of New Haven, State of Connecticut, have invented-certain Improveto facilitate the removal and replacement of the standards, to simplify and cheapen theconstruction, and to render the operation of placing the warp-threads in position easy and expeditious.

The invention consists in a frame having one or more removable sides, and a horizontal tierod extending from side to side of the frame, andserving at once to hold the parts together and to receive and support the warp-threads.

The invention further consists in a series of separating-strips placed between the warpthreads, and so mounted and secured in the frame that they may be readily passed between the warp-threads or removed from such position, as hereinafter explained.

Hitherto it has been the custom, generally, to construct the back standards of this class of looms in the form of a rigid frame, and to arrange therein harness formed of wire, cord, or

a like materials, having closed eyes, through which the warp-threads were carried, and from which they could only be removed by cutting. It has been proposed to dispense with theharness and to employ in lieu thereof a horizontal rod, upon which the warp-threads were to be carried 3 but the frame, being incapable of separation, could only be removed after cutting out the warp-threads. A weaving-heddle has also been framed together and provided with longitudinal tie-rods, which might be removed to permit the separation of the frame; but in the instance referred to there is nothing to indicate that such separation was contemplated, and beiugfurnished with the usualharn ess having closed eyes to carry the warp-threads, the latter musthave been cutbeforethe frame could be withdrawn. Under my improved construction, however, I am enabled to dispense with be readily withdrawn from between them to permit the removal of the frame. The douphealds employed in connection with the herein-described back standard may be of ordinary construction, or they may embody the improvements constituting the subject-matter of an application for Letters Patent filed by Robert Adamsand myself April 27, 1881.

In theaccompanying drawings, Figure 1 represents a face view of myimproved back standard with a portion of the separating-strips in position and one side of the frame separated. Fig. 2 shows an end view of said frame and detached views of the separating-strips. Fig. 3 is a perspective view of the back standard without the separating-strips and their supporting-rods;-and Figs. 4, 5, and 6 are diagrams representing,- respectively, the open 7 shed, the closed shed, and the cross-shed as formed in a loom provided with my improved standards and employing the douphealds shown in, the joint application hereinlbefore referred to.

A represents the standard'as a whole, consisting of upper and lower cross-bars, a and I), each having its ends tenoned, and side bars or pieces, 0 and d, each mortised at its upper and lower ends to receive the tenons of the crossbars. The several parts, being thus formed, are put together as indicated in Figs. 1 and 3, and the whole is then secured and tied together by a tie-rod, B, passing horizontally across the middle of the frame and through the side bars. The rod B is represented as threaded at both ends and provided with nuts 6,- the removal of either of which permits the separation of the parts of the frame or stand ard. If preferred, however, one end of the tie-rod may be headed, and it islikewise obvi- 5 ous that the form and arrangement of the joints and fastening devices may be modified, provided the longitudinal tie-rod be retained.

O C, Fig. 1, represent two rods or wires extending from side to side of the frame A, near the top and bottom thereof, and parallel with the rod B. Upon these rods 0 O are strung a series of separating-strips, f, formed of thin metal or of wire, and with an eye or perforation at each end, as shown in Fig. 2, to permit them to be placed upon the rods or wires 0 O. The strips are separated by washers or equivalent means, and are either bent, as shown, t9 pass the tie-rod B, or are set in front or in rear thereof for that purpose. Thus arranged, the stripsf, together with the tie-rod and the 1011- gitudinal wires (J, form a series of elongated eyes, g, through which the warp-threads are carried.

By withdrawing one of the rods or wires 0 the separating-strips may be swung outward, turning upon the other wire G as a pivot, thus permitting the stripsfto be quickly removed from between the threads; and by loosening the tie-rod B and the second wire or rod 0 sufficiently to release the tenons of the top and bottom pieces a and b the frame may be separated or opened and withdrawn from the loom, as already explained. The wires or rods 0 0, like the tie-rod B, are furnished at their ends with nuts and washers or equivalent fastening devices.

The standard may be used without the separating-strips, if preferred, in which case the rods 0 C may also be omitted, as in Fig. 3.

If desired, strips It may be applied to the standard, as shown in Figs. 1 and 2, to divide the warp-threads; but if used they should be left free at one end, or otherwise arranged to permit the removal ofthe warp-threads between them and the back-standard frame. The back standards, being thus constructed, are introduced into the loom and mounted in the usual manner, one set of warp-threads passing This actionis illustrated in the diagrams, in

which Fig. 4 represents the doups in-action and the back standards separated to open the shed. On the reverse action of the loom the standards remain stationary, as in Fig. 5, in order to permit the formation of the crossshed, Fig. 6, as they also do when weaving in the plain bar to'permitthe two doup-harnesses to weave without stretching the doups, such stretching of the doup-eyes producing a twist,

which of course is not wanted in weaving the 2. A back standard for gauze-weavinglooms,
