SPECIFICATION forming part of Letters Patent No. 403,198, dated May 14, 1889.

Application filed December 21, 1888. Serial No. 294,258. (No model.)

To all whom it may concern:

Be it known that I, FRED LACEY, of Adams, in the county of Berkshire and State of Massachusetts, have invented a new and Improved Loom Attachment for Weaving Center Selvages, of which the following is a full, clear, and exact description.

This invention relates to an attachment for looms upon which splits or more than one width of cloth are woven at the same time, the object of the invention being to produce center selvages; and to the end named the invention consists in the construction and combinations of parts hereinafter fully explained, and specifically pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views.

Figure 1 is a face view of my attachment, the parts being represented as they appear when the shed is closed. Fig. 2 is a similar view, the parts, however, being represented as they appear when the needle-carrying slide has been tilted to the left. sectional view on line :23 0c of Fig. 1. Fig. 4 is a face view of the attachment, the parts being represented as they appear when the needle-carryin g slide has been tilted to the right. Fig. 5 is a similar view, the parts, however, being represented as they appear after the slide has been raised to its upper position and the shed has been formed. Fig. 6 is a side view of the attachment, representing it as it appears'when the shed has been formed, the parts being in the position in which they are shown in Fig. 5. Fig. 7 is a face view of my attachment, representing it as it appears when arranged for use in connection with a loom upon which double-backed fabrics of more than one width are woven. Fig. 8 is a view representing a portion of a piece of fabric in which there are center selvages formed by means of my attachment. Fig. 9 is a view of a fabric wherein three warp-threads instead of two are bound by the whipping-thread. Fig. 10 is a diagram of the double-backed fabric such as is operated upon by the construction shown in Fig. 7, and Fig. 11 is a view of the weave produced by my attachment when Fig. 3 is a crosssuch attachment is employed to weave corded stripes into the body of a fabric.

In the drawings, 10 represents a stiff metallic plate that is arranged for rigid connection with the loom-frame, the plate being placed back of the loom-lay and in front of the harness, a supplemental casting being at times necessary in order to secure a proper adjustment of the plate, said casting being bolted to the frame and the plate being bolted to the casting.

It will be readily understood that the form of the casting above referred to would vary with the form of loom upon which my attachment is to be employed.

Near the lower end of the plate 10 there is formed a long slot, a, through which there is passed a bolt, 11, said bolt passing through an aperture formed in a slide, 12, there to engage a nut, 13. To the upper end of the slide 12 there are secured needles 14 and 14., while to the lower portion of the slide there are ad-' justably connected stop- plates 15 and 15, said plates being provided with lugs or cars 16, which overlap the plate 10, the plates 15 and 15 being connected to the slide 12 by a setscrew, 17 which said set-screw passes through slots 1), formed in the plates, the arrangement being such that the plates 15 and 15 may be moved outward or in ward and their lugs or cars 16 carried toward or from the side edges of the plate 10. Cords 18 and18 are connected to projections 19 and 19, which extend laterally from the slide 12, said cords in turn being connected to the selvage harnesses or levers, as will be readily understood.

The slide 12 carries a spool, 20, upon which there are wound two threads, 0, that are passed through the eyes of the needles 14 and 14., and in order that a proper and uniform tension may be at all times imparted to the, threads I arrange a spring, 21, in a position such that it will bear upon the inner face of the thread wound upon the spool, the spring being provided with an adj usting-screw, 22, whereby its tension may be regulated.

By mounting the spring 21 so that it will bear upon the thread instead of upon the spool proper I secure a uniform tension upon the thread 0, inasmuch as the pressure of the spring decreases as the leverage of the thread decreases-that is, as the thread unwinds so i that the face of the roll approaches the axis of the spool the leverage necessarily decreases and the pressure exerted by the spring also decreases. The warp-threads upon the outside of the inner edges of the two pieces of cloth that are woven together are passed through slots 5 and 5, formed in the plate 10.

When the shed is closed, the parts of my attachment will be in the position in which they are shown in Fig. 1. Then if the cord 18 be drawn upon the slide 12 will be tilted to the position in which it is shown in Fig. 2, whereby the point of the needle 14 will be carried to the left of the slot 5, and the point of the needle 1a will be carried to the left of the slot 5that is, to a point between the slots 5 and 5, as shown in Fig. 2. Then if the cord 18 be drawn upon as the shed is formed the slide 12 will be raised and the threads 0 carried up with the upper warpthreads and to the left of the threads which pass through the slots 5 and 5. After the shuttle has passed through the shed and the pick has been formed the tension upon the cord 18 is relaxed and the slide 12 will lower to the position in which it is shown in Fig. 1.

Upon the formation of the next shed the cord 18 is drawn upon, and as the cord 18 is so drawn upon the slide 12 will be moved first to the position in which it is shown in Fig.

4, and then to the position in which it is shown in Fig. 5-that is, to a position such that the needle 11 will be to the right of the slot 5, and this alternate movement being continued will result in the weave shown in Fig. 8, the binding-cord being carried as represented in said figure. As the picks are formed they are out.

If desired, three or more warp threads or yarns might be passed through the slots 5 and 5*,01', if desired, the cords 1S and 18, instead of being drawn upward alternately, might each be drawn upward twice in succession, or each three or more times in succession. (See Fig. 9.)

From the above description it will be seen that the tilting of the slide 12 can be readily controlled by properly adjusting the plates 15 and 15.

If double-backed fabrics are to be woven, I would connect a slide, 12, to the upper end of the plate 10, this slide being drawn back to its normal position by a spring, 30. In other respects the slide 12 would operate exactly as would the slide 12.

Although the attachment above described is designed more especially for use in the formation of inner or center selvages, still the attachment could be very successfully employed in the formation of corded stripes through the body of a fabric. (See Fig. 11.)

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent 1. The combination, with the longitudinally-slotted plate adapted to be connected to a loom-frame, of a tilting needle-carrying slide, a bolt extending through said slide and slot, and laterally-extending stops projecting from opposite sides of the slide and embracing the said plate to limit the tilting of the slide without interfering with its sliding movement, substantially as set forth.

2. The combination, with the slotted plate, of the needle-carrying slide thereon, having spool-bearings, substantially as set fort-h.

3. The combination, with the plate 10, having a longitudinal slot, at, and parallel threadslots 5 5, of the tilting needle-carrying slide, through which and the said slot at a bolt, 11, passes, and the laterally-adjustable stops on the slide embracing the sides of the plate, and the lugs or cars 19 19 projecting from opposite sides of the slide for connection with selvage harness or levers, substantially as set forth.

1. The combination, with a slotted plate arranged for connection with a loom-frame, of a tilting needle-carrying slide mounted to move vertically upon said plate and adapted to carry a spool, and stop-plates carried by the slide, substantially as described.

5. The combination, with a slotted platcarranged for connection with a loom-frame, of the needle-carrying slide mounted to move vertically on said plate and arranged for connection with a harness, stop-plates carried by the slide, spool-bearings upon the slide, and a spring projecting between the said bearings, substantially as described.

6. The combination, with a plate, 10, ar-.

ranged for connection with a loom-frame and formed with slots 5, 5, and a, of a slide, abolt connected to the slide and passing through the slot at, needles carried by the slide, plates 15 and 15, formed with lugs or cars 16, and a set-screw by which said plates are connected to the slide, the slide being arranged for connection with selvage harnesses or levers, substantially as described.
