ARTHUR EDVTABD strao'on, or LONG EATON, ENGLAND.

nnnn non Loci/La Specification of Letters Patent.

Application filed July 24, 1917. Serial No. 182,531.

To all whom it may concern:

Be it known that I, ARTHUR EDWARD S'rRoUD, a subject of the King of Great Britain, and a resident of Long Eaton, in the county of Derby, England, have invented new and useful Improvements in Reeds for Looms, of'which the following is a specification.

This invention relates to improvements in reeds for use in looms designed to produce a number of separate narrow fabrics such as tapes, ribbons and the like in parallel planes which are at right angles to the width of the reed, and has for its object the production of a reed providedwith reed wires or dents whichv extend the full width of the reed and simultaneously heats up the wefts in all the fabrics, also the flexible spacing of such reed wires or dents by helically coiled springs, by and through which arrangement knots and irregularities in the threads can passbetween the reed wires, and by which the distance between adjacent fabrics can be reduced to a minimum.

In the accompanying drawing Figure 1 i the plan of a portion of the improved reed sufficient for one piece of fabric. I

Fig. 2 is a longitudinal section of Fig. 1.

Fig. 3 is a transverse section of Fig. 1, and

Fig. 4 is a part plan of the improved reed.

In narrow ware looms of the usual kind there is a separate reed for each piece of fabric and all the reeds are carried by the same frame. In each reed the ends of the wires are rigidly connected to end pieces and the wires between the end pieces are not sufficiently flexible to allow the irregularities in the warp threads to pass between them and consequently there are a large number of threads broken, also the end pieces to each reed increases the distance between the pieces of fabric. I

According to this invention the reed is provided with two side pieces 1 which GX tend the full width of the reed and are connected together at intervals by cross bars 2, the distance between which is at least sufficient to allow of one shed being formed and may be sufficient for the formation of two or more sheds. At each end of the reed the wires 3 are carried by end pieces 4: to which they may be rigidly attached, or in which they are so held that end movement of the wires is prevented; Mounted upon each of the cross bars there is a helically coiled spring 5, which is preferably hardened and tempered, and is so wound that the pitch of the coils is the same as the required distance between the reed wires, which distance depends upon the gage or coarseness of the fabric to be made. Ihe wires 3 extend the full width of the reed and their ends are connected to the end pieces of the reed. Between these end pieces the reed wires rest upon the cross bars 2 and are laid'upon these bars between the coils of the springs or are threaded through such coils. A top wire 6 is also threaded through the coils of each spring and rests upon the top of the reed wires for the purpose of holding the latter from accidental movement in a vertical direction.

In a reed constructed according to this invention the reed wires are accurately and flexibly spaced by the coiled springs and in such an arrangement the reed wires, are easily moved sidewise by irregularities in the warp threads and allow such irregularities to pass between the wires or the wires passing to and fro over the irrgularities, also the small space occupied by the cross bars and springs permits of the shuttles being worked at a minimum distance apart.
