HEDDLE-FRAME CONNECTION FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 247,770, dated October 4, 1881.

Application filed February 21, 1881.

which move them by means of leather straps,

whichlatter,between the ends of thelevers and heddle-frames, extend about and bear against sheaves or pulleys, as in the Orompton loom. Those'parts of the heddle-connections which bear against the sheaves are made narrower than the ends of the connections which are joined with the heddle-frames and with the levers, and are usually rounded to fit the grooves in the said pulleys. As usually produced, these straps to form the heddle-connection are cut from aside of leather, the straps being of uniform width from end to end, the width being that considered necessary for that part of the said strap or heddle-frame connection which is to bejoined with the levers and the heddleframes, and the central portions thereof which are to bear against the sheaves are afterward cut away, the material so cutaway or removed being Wasted, which results in very considerable loss, as the leather used is usually of the best quality.

The object of my invention is to prevent this waste of leather and cheapen the construction of heddle-frame connections; and this I have done by first cutting from a side of leather certain strips or pieces of the exact width and length desired for the sheave portions of the connections which are to rest upon the sheaves, and then I cut out certain end pieces of proper width to be applied to the levers and heddleframes, double the said end pieces, and insert between them the ends of the narrower sheave portions of the heddle-eonnections, uniting the said end pieces thereto by means of a strong cement.

Figure 1 shows one of my improved heddleconnections, one-half of one of the end pieces (No model.)

being cut away. Fig. 2 is a side elevation or edge view of Fig. 1, the part cut away from the right of Fig. lbeingretaiued, and showing one end piece spread open and the other closed. Fig. 3 represents one of the old forms of heddle-connections, the dotted lines showing the material which is cut away and wasted in its formation. Fig. 4 represents one of my improved end pieces laid out flat to show the hole made in it to receive the end of the sheave portion of the heddle-connection, and Fig. 5 is a modification.

In the manufacture of heddle-connections, as now commonly practiced, the side ot'leather is cut to form strips of the width considered necessaryfor the flatends athereof, (see Fig. 3,) which are to bejoined to the heddle-levers and heddle-frames, and subsequently these strips are reduced in width for a portion of their length, cutting away the leather, as shown by the dotted portions b leaving the narrow sheave portion b, which is afterward rounded or shaped to properly fit the grooves of the usual sheaves over which the connections run. Such mode of manufacture results in a great waste of valuable stock, as the leather employed is of the best quality and consequently expensive.

In my improved heddle-frame connection I denominate that portion thereof which bears upon the sheaves as the sheave portion, and the portions which are to be connected in the usual manner with the usual levers and heddleframes as the end pieces.

In Figs. 1 and 2 the sheaveportion cis made ofjust the size desired to properly fit the usual sheave, and each end 0 of the portion cis flattened and preferably perforated or slotted, as at 0 Making the sheave portions separately of the proper size obviates waste of leather resulting from the old plan shown in Fig. 3. The end pieces, d 6, (see Fig. 4,) when out from the side of leather, are of the same width as the end pieces shown in Fig. 3. These end pieces are provided with slits or small openingsf, (see Fig. 4,) into which Iinsert the ends 0 of the sheave portions, as at the right of Fig. 2, after which both legs of the end pieces are brought in contact with the parts 0, as at the left of Fig. 2, a proper amount of any suitable strong paste for leather being interposed, and

then the end pieces and portions, 0, are pressed firmly together, the joint so made being very strong, eflectually preventing the pieces 0 from being drawn from between the end pieces. In this way I am enabled to save all the stock ordinarily wasted in the old plan and produce an article equally as serviceable at a much cheaper price.

I have described sheave portions and end pieces as made of leather, as I prefer them to be; but it is obvious that I might employ for the sheave portions braided, woven, or twisted cord, as in Fig. 5, confining the ends of such a sheave portion slightly unraveled between the end pieces. Instead of employing leather for the end pieces, I might use strong heavy duck or other woven,1nateria1, as at 1, Fig. 5.

The openings 0 in the ends 0 of the sheave portions enable the end pieces and paste to have a stronger junction with the parts 0 than if the openings were omitted.

If desired, I might secure the parts 0' and d or 0 by means of stitches.

I claim- 1. As an improved article of manufacture, the herein-described heddle-frame connection, composed of a sheave portion, 0, and an independent end piece, 0, between the folded part of which the end of the sheave portion is inserted and held, substantially as shown and described.

2. The leather sheave portion 0, flattened at its end and perforated or slit at 0 combined with the broader end piece secured thereto and holding the end of the sheave portion, substantially as described.

In testimony whereofI have signed my name to this specification in the presence of two subscribing witnesses.
