In the construction jacent the frame. Thefsecond instance above illustrated in the several'gures of the drawing,4

named, is objectionable due to the fact that the the reed dents 7,k having been placed in their reed heretofore formed with pitch covered respective positions by a reed setting machine strings are so resilient that they are not adaptwhich automatically winds the reeds with the ed to the finer weaves but are suitable only for pitchcovered string 9, are then first spaced in the coarser fabrics. usual manner by metallic spring spacers after 4o The above objects and disadvantages, 4are overwhich the dents 7 are in a position shown in 40 come by providing or forming a weaving loom Figure 4, wherein the ends of the dents 8 are reed by rst spacing and retaining the dents to shown extending above the side ribs 6. In the the side ribs by means of pitch covered strings present construction, the ends 8 extend unusually and then dipping the ends of the dents which further than the present day construction for a extend a distance beyond the side ribs into a bath. purpose which will be described hereinafter. 45 of molten solder whereby the same are rigidly The dents 7, having been placed in their reheld in place relative to the frame and to each spective positions by a reed setting machine which other. Should solder flux or acid still remain on automatically winds the reeds with the pitch covthe ends of the reed dents, after the same have ered string 9, are thus held to the ribs 6 in their been secured,` the same will not sink down to the spaced relation. The reed is thus set up into the operative spaces of the reed dents to cause the desired shape and size and the dents '7 spaced to same to deteriorate or otherwise become broken, their desired positions. due to the fact that the pitch covered strings in- The dents 7 having been placed in position and tercept any acid or solder flux and retains the secured by thel tar covered twine 9, the frame same or restricts the same directly to the ends pieces 10 are placed over the ends 8 and held in position by temporary fastenings or clips, after which the ends 8 of the dents 7 are dipped into a flux or soldering acid and then dipped into a molten bath of solder, whereby the solder adheres to the ends 8 of the dents and holds the same in a rigid spaced relation, also serving to hold the side frame members 1G in position, as illustrated in Figure 1. Figure 3 also illustrates the solder 11 between the dents 7 at the ends 8 thereof and shows the manner of securing the side frame pieces 10 in position'whereby the weaving reed is completed.

It will readily be observed that any soldering acid or soldering iiuX which does not become removed during the soldering operation will not moisten the reed dents 7 by capillary attraction, as the pitch covered twine 9 intercepts any such acids or flux from passing from the ends 8 to the operative portion of the dents '7. This method of forming weaving loom reeds produces `a reed in Which the dents 7 have more resiliency than the all-metal reeds now in common use and it also forms a weaving loom reed which will last a considerable length of time, due to the fact that the same is free from deterioration at the junctures of the dents 7 and the pitch covered twine 9.

It is to be understood, that the form of invention herein shown and described is to be taken as a preferred embodiment of the same and that various changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the sub-joined claim.

Having thus described the inventionfwhat is claimed is:- A

A loom reed comprising dents accurately spaced at equal predetermined distances from each other, means rigidly joining the ends of said dents together and resilient dam means interposed between each dent inside of said rigid joining means, comprising resilient pitch impregnated cord wound around metal ribs on each side of said dents near each end thereof with a coil between each dent, whereby said dam means may prevent the soldering acid or iux from attacking the dents in use.
