To ("r/U whom it may concern.-

Be it known that I, HOWARD D. COLMAN, a citizen of the United States,residing at Rockford, in the county of I/Vinnebago and State of Illinois, have invented a new and useful Device for Correcting Errors in Drawing in arps, of which the following is a specification.

This invention relates to the art of weaving, and refers particularly to a device for correcting drawing-in errors in a loom-warp.

As is well known, loose ends appear in and disappear from the loom-warp as said warp is unwound from the warp-beam. In order to insure that the weaving shall be perfeet, it is necessary to make these ends complete by tying on threads from the loomwarp or in the case of extra threads to withdraw such threads from the loom-warp, transferring them into the selvage of the loom-warp.

The object of this invention is the production of a device for directing a thread from a point on the warp-beam to a place in the loom-warp where a thread is missing, also for directing an extra thread appearing upon the warp-beam to the selvage of the loom-warp.

In the accompanying drawings, Figure 1 is a View of a portion of a loom in rear elevation, showing the application of my device to said loom. Fig. 2 is a vertical section through such 100111 on dotted line 2 2 of Fig. 1. Fig. 3 is a perspective view of one end of the guide-bar of my invention. Fig. 4 is a perspective view of one of the metallic guideclips adapted to be placed upon said guidebar. Fig. 5 illustrates the guide clip as formed from wire.

In the embodiment herein shown of this invention I provide a weaving-loom having a supporting-flame A, upon which is mounted in any suitable manner awhip-roll B, extending the full width of the frame A. A warpbeam C is rotatably mounted upon the supporting-frame A. The body of warp-threads extends from the warp-beam C over the whiproll B, said threads passing over and under the lease rods D to the harnesses. (Not shown.)

A guide-bar 1, adapted to extend parallel with and located slightly rearward from the whip-roll B, is held in position with relation to said whip-roll by means of two hooked supporting-rods 2, one end of each of said rods being secured rigidly within a suitable opening in the guide-bar 1, the other (forward) end of the rod being bent downwardly and rearwardly to form an attaching-hook 3. The supporting-rods 2 are adapted to rest upon the whip-roll B, the hooks 3 of said supporting-rods engaging the forward and lower edge of said whip-roll. By means of this. hook connection the guidebar 1 may readily be removed from the loom.

Spring guide-clips 4, formed from wire, sheet metal, or other suitable material, are adapted to be placed upon the guide-bar 1, being held in position upon said bar by reason of the elasticity of said clips. Each of the spring-clips 4 comprises two opposing grasping-fingers 5, with connecting top bar 6. A tongue 7 is out out from the middle portion of each of said clips 4, which tongue is raised above the top bar 6 of the clip and at its free end extends downwardly, outwardly, and thence upwardly to form the guide-hook 8. The spring-oh s 4 may be placed in pairs upon the gui e-bar 1 at any point in its length with the guide-hooks 8, one on each side of the bar 2. The pressure of the springfingers 5 of the clips 4 upon the sides of the bar 1 holds each clip securely upon said bar and prevents longitudinal movement of the clips upon the bar.

The modified form of clip shown in Fig. 5 is similar to the sheet-metal clip shown in Fig. 4. In the wire clip, however, a guide-loop 9 is provided upon one side of the clip, the purose of which loop -is to direct the thread om the warp-beam .to the guide-hook 10.

When an extra thread appears in the loomwarp said thread is guided to the edge of said warp among the selvage, threads by placing two guide-clips 4 upon the guide-bar 1, one of said clips, with its uide-hook 8, extending rearwardly from the Ioom at a point coincident with said extra thread, the other clip, with its guide-hook 8, extending towardthe loom at a threads. T e extra thread is then passed from the warp-beam over the guide-bar 1 and upon the guide-hooks 8 of the two clips 4 just mentioned and its end secured among the selvage-threads of the loom-warp. In the same manner a thread may be taken from among the selvage-threads of the warp oint in a line with the selvagei in the loom-Warp.

, tively di It is clear that various changes and modifications may be made in this invention Without departing from the spirit and scope thereof, Wherefore I desire to have it understood that Ido not intend to limit myself to the precise form of mechanism illustrated,

.vention broadly and in all its various forms and applications.

but, on the contrary, desire to claim said in- I claim as my invention 1. In a device for correcting drawing-in errors, the combination With a loom, of movable thread-guides for directing a thread from its position on the Warp-beam to a relaerent position in the loom-Warp.

2. In a device for correcting drawing-in errors, in combination, a guide-bar and movable thread-guides.

3. In a device for correcting drawing-in errors, m combination, a guide-bar and thread-guides adapted to have a frictional engagement With said guide-b ar.

4. In a device for correctingv drawing-in errors, in combination, a guide-bar and thread-guides, each thread-guide having a spring-clamping finger for said bar and a guide-hook for the thread.

5. In a device for correcting drawing-in errors, in, combination, a guide-bar, and thread-guides formed from spring material and adapted to engage said bar, each threadguide having a guide-hook for the thread.

6. In a device for correcting drawing-in errors, in combination, a guide-bar, and thread-guides formed from sheet material having clamping-fingers adapted to frictionally engage said bar, each thread-guide having a guide-hook for the thread.

7. In a device for correcting drawing-in errors, the combination With a loom of a guide-bar supported upon the loom, rear- Ward of the whip-roll and thread-guides movably supported on said guide-bar.

8. In a device for correcting drawing-in errors, in combinatioma guide-bar, supporting-arms for said guide-bar adapted to rest upon the hip-roll of a loom and engage the lower edge of said roll, and thread-guides movably supported on said guide-bar.
