LOOM FOR WEAVING BROAD SILK GOODS.

SPECIFICATION forming part of Letters Patent No. 267,777, dated November 21, 1882.

Application filed April 19, 1882.

To all whomit may concern:

Be it known that we, GEORGE OR-oMProN and HORACE WYMAN, of the city and county of Worcester, State of Massachusetts, have invented an Improvement in Looms for Weaving Broad Silk Goods, of which the following description, in connection with the accompanying drawings, is a specification.

7 Our. invention relates to looms more especially designed for weaving broad silk goods for dresses, handkerchiefs, &c., as contradistin guished from narrow goods, such as ribbons; and has for its object such a construction of the parts thereof as will enable bowshuttles to be used in connection with a series ofshiftingshuttle-boxes, thesaid shuttles being actuated by pickers sliding on guide-rods.

In the manufacture of silk goods it is necessary to lay the silk filling as closely as possible up to the fell of the cloth, and to do this shuttles for silk-Weaving have been provided atone side with a bow in which is placed the I delivery-eye.

For the most rapid and economic production of fancy and plaid silks for dress-goods, handkerchiefs, 850., the bow-shuttle should be used in a loom having shifting shuttle-boxes actuated by power; but as such power shifting shuttle-boxes are now made it is impossible to employ such a shuttle, for the reason that the bow cannot pass into or from the cells of the shuttle-boxes, as the sides of thelatter are commonly closed near the reed; and, further,

with all such shifting shuttle-boxes the hinders which co-operate with the shuttles are so shaped that the bows of the latter cannot pass the free ends of the binders.

To enable us to employ in looms having a power-actuated shuttle-box a fly-shuttle hava bow and moved with a sliding or rawhide picker held on a guide-rod,we were obliged to devise a novel shuttle-box, having its front, or that side from which the boW of the shuttle is toprojeet, open beyond the side edge of the shelf, or beyond that part of the shuttle-box shelf on which the under side of the shuttle directly rests and slides, in order that the bow of the said shuttle might have an open space (No model.)

in which to travel as the said shuttle enters and leaves the box. To provide for this and yet keep the shuttle from leaving the side of the shelf, we have provided the box with a down ward projection from the top of each cell. To support the silk filling beyond that portion of the shelf on which the body of the shuttle rests and travels, we have provided each shelf with an extension beyond its straight or open side at that end of the shifting box nearest the reed or loom side, or the inner end of the said box and to enable the binders to be operative upon the shuttles we have made each binder quite narrow at its front or free end, and have supported the said free end of the binder upon a projection or rest located above the center line of the cell of the shuttlebox, covered by the said binder, and in which the shuttle travels, thus enabling us to form an open space below each binder from its pivoted or rear end, past its free end,,for the free passage of the bow of the shuttle from a cell of the shuttle-box.

Figure 1 represents in front elevation a sufficient portion of the upper part of the lay of a shifting shuttle-box or gingham-loom, with shuttle-boxes and shuttles to illustrate our invention, the center of the lay and reed being broken outto save space on the drawings. Fig. 2 is aplan view of Fig. 1, the said figure also showing portions of the breast-beam and its attached parts, which are omitted from Fig. 1. Fig. 3 is a vertical cross-section taken through the shitting shuttle-boxeson the line mm, Fig. 1. Fig. 4 is a section of the single box at the opposite end of the loom on the line 9 Fig. 1. Fig. 5 represents one of the binders detached from the loom. Fig. 6 is a detail view of the guide employed on the lay next the receiving end of the shifting shuttle-box. Fig. 7 is a view of the guide which is located on the lay near the single box. Fig. 8 is a top view of the bow-shuttle to be used.

The frame-work is marked A.

The lay A has connected with one end of it the .usual metallic frame, B, in which the series of shuttle-boxes O is guided and made movable vertically. The shuttle-boxes G are supported on 'a rod, G, which in practice will be connected with and actuated by a shuttle-box lever-such, for instance, as. represented in United States Patent granted to Horace Wyman, No. 197,754. December 4, 1877.

At one side of the series of movable shuttleboxesO (herein shown as the rear side) is a guide-rod, a, on which is placed a rawhide picker, M, of usual construction, it being actuated to strike and throw the bow-shuttleD across the warp from one of the cells of the shifting shut tle-box O to the single box at the opposite end of the lay, or vice versa, by means of a pickerstick, a (shown in Figs. 1 and 2,) which may be vibrated as in United States Patent No. 230,243, granted to G. Crompton and H. Wyman, or in other well-known manner. The shuttle D (see enlarged view, Fig. 8) has upon one side of it a'bow, b, provided with a threaddelivery eye, I), and with suitable tension devices, b to act upon the silk weft taken from the bobbin b This shuttle we do not herein claim. The series of shifting shuttle-boxes U is herein shown as having four cells, in one only of whichviz.,the third box from thetopis a shuttle. The shuttles when in their cells rest upon the shelves 0 e, or horizontal portions which constitute the bottom pieces of the cells, and by which the shuttles are supported when in the shifting box 0. The series of boxes B, at its front side, is provided with a series of downward projections, 0 (shown best in Fig. 3,) which prevent the escape of the shuttles from the front sides of the shelves on which the shuttles are moved.

The shifting shuttle-box is provided at that part of it which forms the top of a cell and the projection 6 with a horizontal projection or rest, f, on which the reduced or narrow point or free end of the binder d rests, and the binder is made sufficiently narrow, as shown in Figs. 1' and 3, to leave a free longitudinal space from the point 2 of each binder to its free end to permit the passage of the how I) of the shuttle D past the free end of the binder as the shuttle enters or leaves each cell of the shuttle-box.

Each shelf or part of the shuttle-box on which the shuttle is directly supported, or, in other words, the bottom piece of each cell of the box, has a forwardly-projecting portion, 3, on which rests the weft-thread between the bow of the shuttle and the selvage, and rising from this projection 3 is an upright shoulder, 4, which-prevents the weft-thread from being thrown out so far as to be caught by the protector-finger you the usual protector-rod, 9

Each binder near its outer or free end has a projection, 5, of such length that when-the binder acts on a shuttle D the outer end of the projection 5 (see Figs. 2 and 3) extends outward as far as or past the inner face of the shoulder at. The projection 5 of each hinder, except the one which co-operates with the uppermostcell of the shuttle-box, when pressed outwardly by the presence of a shuttle in its cell, serves to support the weft extended from the bow of the shuttle in the cell of the box above it to the selvage of the cloth, thus preventing the said weft-thread from falling into the path of the movement of the protectorfinger g, and being broken by the said finger catching against it.

, 72 represents the breast-beam.

Fig. 3shows the binder of the third box from the top as pressed out by the shuttle in that box, in which condition it would support the weft-thread of a shuttle in the second cell from the top of the boxes; but in Fig. 3 we have omitted the shuttle from the second box.

The binders (1 are acted upon by springs d As shown and described, the side of the shuttle-box opposite each cell thereof is provided with a space or opening, through which the bow b of the shuttle D is free to travel as the said shuttle enters and leaves a box, the bow passing below the binder and beyond its free end without coming in contact with the binder.

The metal guide h (shown in Figs. 1 and 2, and on a larger scale in Fig. 6) has ears 9 10, by which to attach it to the lay at the receiving ends of the shuttle-boxes, and a shoulder, 1.2, to assist in keeping the shuttle on the lay, and the front of the said guide is curved or opened outwardly at or near its center opposite the line of movement of the bow b of the shuttle, to form aspace, 13, (see Fig. 6,) through which the bow of the shuttle may pass as the latter enters and leaves a cell of the movable box G.

The lay is connected with the usual connecting-rods, A The right-hand end of the lay, viewing Figs. 1 and 2, has a picker, pickerstick, and guide-rod such as are employed at the left-hand side of the loom. At the right hand of the lay (see Figs. 1 and 2) there is but one binder, j, acted upon by a spring, k. This binder j has its free-end 15 rested on a guide, a, shaped as shown in Fig. 7, thus leaving below the under side of the binder a free open space, m, for the passage of the how 1) into and from the box at the right of Fig. 1. The guide a (best and fully shown in Fig. 7) also has its front portion or wall so shaped as to leave a curved or outwardly-openingportion,0, to permit the ready passage through the guide of, the bow of the shuttle when entering or leaving the shuttle-box next to it.

The operative parts of the loom (not herein shown) may be the same as in the patents hereinbefore referred to.

The protector-rod has a dagger, 1", which, when the shuttle fails to be properly boxed, acts on the lever s and releases the shipperhandle t from its notch in the plate t, all as common.

We claim- 1. The bow-shuttle and the shuttle-box having several cells, each provided with the binder-rest f, having an open space below it leading into the shuttle-box, combined with shuttle enters or leaves a cell of the shuttle box, substantially as described. I v

2. The bow-shuttle and meansto move it, combined with the shuttle-box, having two or more cells provided each with the projection 0 extended downwardly across the open front of the cell of the box to keep the shuttle from escaping from the open front or sideof the said cells, yet leaving a space below it for the pas sage of the bow of the shuttle as the latter enters or leaves a cell of the shuttle-box, substantially as described.

3. The two or more celled shuttle-box having the sides and inner ends of the cells open or unobstructed, as described, and each cell provided with a projection, 0 and with a projection, 3, near its inner end extended out horizontallybeyond the acting portion of the proj ection 6 the said projection being adapted 2 5 to support the weft-thread, substantially as de scribed.

4. The shuttlebox having two or more cells and formed with projections e", f, and 3, and shoulders 4, and the pivoted binders, having 0 the projections 5 to support the weft or shuttle threads, combined with the protector-finger g and the protector-rod g upon which said finger is secured, substantially as described.

In testimony whereof we have signed our 5 names to this specification in the presence of two subscribing witnesses.
