FIG. I

Patented Get. 10, 1933 HEDDLE OR DROP-WIRE Edwin Smith, Providence, R. I., assignor to Rhode Island Warp Stop Equipment Company, Portland, Maine, a corporation of Maine Application November 4, 1931. Serial No. 572,939

8 Claims.

My invention relates to an improved drop wire devised particularly for use on yarns, threads and ti e like running at high speed, and more especially for use with silk and rayonn At high speed, silk and rayon cut the steel of the ordinary drop-wire, and in turn are chafed and cut by the ordinary drop-wire after being used for a relatively short time.

My invention is shown in the accompanying drawing in which:

l is a View looking toward one face of my improved drop-wire;

Fig. 2 is a view looking toward the reverse face;

Fig. 3 is an enlarged fractional view of so much of Fig. l as is shown between the lines aa and 6-2);

Fig. 4 is a sectional View of Fig. 3 on the line l-- and looking in the direction of the arrow (3;

5 shows the clip 8; and Fig. 6 is sectional of Fig. 3 on the line 6-6.

Similar numerals -refer to imilar parts throughout the several views.

The drop-wire 2 is made with the usual slot 3 to receive the contact bar. Above this slot is a contracted portion 4 Figs. 1 and 3. Just above the contraction 4 the drop-wire again widens forming a portion or area 5 with exposed edges of curvilinear contour. Preferably, these contours are circular in curvature with the center of contour substantially coinciding with the center of the thread eye or the eye piece 6. 7

Above the thread eye, the drop-wire narrows again, the narrowed portion extending upward to form a tab or handle by which the dropwire can be lifted if and when desired.

In the middle of the curvilinear enlargement is a hole conforming to the general form of eye piece 6.

The metal at the edge of this hole is formed or drawn to make the retaining flange 7. The effect of this drawing or flanging is to produce a seat, to hold the eye piece 6. The eye piece 6 is preferably in the form of a circular annulus although it might be oval, elliptical or of any desired form. The eye piece is made of glass or porcelain or other material of vitreous substance or surface.

To hold the eye piece to its seat, I provide a clip 8, shown apart and by itself in Fig. 5. This clip 8 is a shallow cup of thin material having a middle opening 9 and a flange 10 corresponding to the flange 7 on the. body of the drop-wire. The inner diameter f--f of the dropwire opening, and the inner diameter ee of the clip opening are substantially identical and smaller than the outside diameter g--g of the eye piece 6, so that when the clip is secured to the drop-wire the eye piece 6 cannot fall out of its seat or socket.

At opposite points 1111 the wall or flange of the clip 8 is cut away, Fig. 5, to fit over the narrow or contracted portions of the drop-wire, as shown more particularly in Figs. 2 and 6.

The unremoved portions 12l2 of the wall or flange of the clip 8 are clinched down upon the drop-wire 2, after the eye piece 6 is in its place, thus locking the eye piece to the drop-wire, Figs. 2 and 6.

Without limiting myself to the precise form of arrangement of my improved drop-wire, I claim:

1. The combination with a drop-wire, of an eye-piece mounted thereon a clip for holding said eye-piece in position on the drop-wire, and means to secure said clip to the dropovire.

2. The combination with a drop-wire formed with a hole, an eye-piece, and a clip to hold said eye-piece to the hole, said drop-wire and clip having interengaging means for securing the clip to the drop-wire.

3. The combination tvith an eye-piece, of a metal drop-wire having a hole of the same shape as said eye-piece but smaller, the metal about the hole being shaped to form a seat for said eye-piece, and a clip to fasten said eyepiece to the seat.

4. The combination with a drop-wire having a portion with curvilinear contours, and an opening in said portion, of a clip with flanges conformed to curvilinear contours, which flanges are bent down upon the drop-wire to hold said clip.

5. A clip for securing an eye-piece to a drop wire havin an opening for the eye-piece and opposing flanges for clinching the clip to said drop-wire.

6. A clip for securing an eye-piece to a drop, wire having a hole with the substance of the clip about the hole formed to make a seat for the eye-piece and having projections for attaching the clip to the drop-wire.

7. The combination with a drop-wire formed with an opening bounded by an offset seat, of an eye-piece shaped to fit Within the opening in the drop-wire against its seat, and a clip secured to the drop-wire and having an opening with a seat conforming to the side of the eyepiece opposite from its side engaging the first-- named seat.

8. The combination with a drop-wire having an opening bounded by a seat offset from the plane of the drop-wire, of an eye-piece received in said opening abutting its seat, and a clip having an opening with a seat corresponding to that of the drop-wire, said clip secured to the drop-wire to hold the eye-piece against the seat thereof.
