3 Claims.

This invention relates to reeds, used in warping machines or the like, for the purpose of spreading the warp ends uniformly as the same are fed in a sheet to a beam preliminary 'to the weaving of the fabric. More specifically considered, the invention relates to reeds of the type which are known as fan reeds, in which'the reed dents are spread from the bottom upwardly so that the same are more widely separated at the top than at the bottom. This arrangement is provided so that by raising or lowering the reed to the proper position, the warp threads which pass therethrough will be evenly disposed as the same are wound on the beam.

The principal object of the present invention is to provide a novel form of reed, for use in warping machines and the like, which is so constructed and arranged that a greater spread of the reed dents is obtainable, thus reducing the number of reeds required to make up a complete set for a particular warping machine.

The nature and characteristic features of the invention will be more readily understood from the following description taken in connection with the drawing, in which Figure 1 is an elevational view of a reed, for warping machines and the like, embodying the main features of the present invention.

Fig. 2 is a transverse section thereof, taken on the line 2--2 of Fig. 1.

It should, of course, be understood that the description and drawing herein are illustrative merely, and that various modications and changes may be made in the structure disclosed without departing from the spirit of the invention, for example, in the drawing there is illustrated a type of construction in which the reed is made entirely of metal with the dents soldered in place, but, on the other hand, the reed could, if desired, be made of the common pitch band construction, or in any `other preferred manner.

Referring to the drawing, in the particular embodiment of the invention therein shown, the reed dents 5, which are spread from the bottom ltoward the top in a fan like arrangement, are of the usual type and made of thin at strips of metal.

As shown, the dents 5 are spaced by being disposed in the convolutions of the usual coil springs 6 and I at the top and bottom of the reed, also on each side of the reed, at the top and bottom, the facing strips, 8 and 9, forming portions of the frame, are provided. All of the Darts above mentioned are soldered to each other in the usual and customary manner.

At each end of the reed, immediately adjacent the last dent thereof, there is provided a thicker metal strip l0, which serves to reinforce the structure, and is fixedly secured to the other parts by soldering or otherwise'.

Also, at each end of the reed, there is provided a strut Il, the lower portion l2 of which extends vertically, and theupper portion I3 of which is inclined at the same angle as the adjacent end dents and the strip l0. The members Il constitute the end struts of the frame and are iixedly secured at their upper and lower ends t0 the facing strips 8 and 9, at the top and bottom of the reed respectively.

By this peculiar arrangement of the end struts l I, arnuch greater spread of the reed dents is possible and as a result thereof, a smaller number of reeds will be required in a given set required to equip a warping machine. The vertical portions of the end struts Il will extend between the side frames of lthe warping machine but, as the plane of the warp sheet is above the tops of the side frames of the warping machine, the upper corners of the reed may extend over said side frames and in this manner the range of the reed will be greatly enlarged.

I claim:

1. A reed for warping machines and the like comprising a plurality of dents made of thin flat metal and arranged in fan like formation, and a frame for supporting said dents, said frame having top and bottom lmembers and end struts connecting said top and bottom members, the upper portions of said end struts being inclined outwardly substantially parallel to the dents at the respective ends of the reed, and the lower portions of said end. struts being substantially vertical, and reinforcing strips disposed immediately adjacent the end dents and extending parallel thereto, said reinforcing strips being interposed between the end dents and the end struts of the frame.

2. A reed for warping machines and the like comprising a plurality of dents made of thin flat metal and arranged in fan like formation, spacers for the upper and lower ends of said dents, whereby said dents have a greater spacing at their upper ends than at their lower ends, and a frame for supporting said dents, said frame having top members secured to the top ends of the dents along the opposite outer side edges thereof, bottom members secured to the lower ends of the dents along the opposite outer side edges thereof and extending beyond the lower N ends of the outenmost dents, and end struts extending between said top members and said bottom members and secured to said members at the outer ends thereof, said end vstruts at the upper portions thereof being inclined substantially parallel to the dents at the respective ends of the reed and the lower portions of said end struts being substantially vertical.

3. A reed for warping machines and the like comprising a plurality of dents made of thin at metal and arranged in fan like formation, spacers for the upper and lower ends o f said dents for spacing said dents at their upper ends at least twice as far as at their lower` ends, and a frame for supporting said dents, said frame having top strip members secured to the' topv ends of -the dents along the opposite outer side edges thereof and beyond said spacers, bottom strip members secured to the lower ends of the dents along the opposite outer side edges thereof and extending beyond the lower ends of the outermost dents, and end struts extending between said strip members and said bottom strip- -membersvand secured between said members at the outer endsv thereof, said end struts at the upper portion thereof being inclined substantially parallel lto the dents at the respective ends of the reed and the lower portions of said end struts being substantially vertical.
