= 1 Claim. illh-is invention rela'tes to loom reeds ,and more especially ==to the type-of lloom reed made entirely of metal and having a. covering or adapted for the upper and lower edges :to convert what is known as the silk type of loom reed to a-zcotton type, or without the covering, the reed can be used as a silk reed.

Heretofore in the manufacture of metallic loom reeds, the splits, are arranged by machinery in a horizontal plane in spaced relation to each other and then a coiled spring is passed down between the splits with a coil .of the spring disposed between two adjacent splits to thus form dents between the splits and to hold them in proper spacedrelation. "Then,- --suitablesmall half-round members are-passed -on each side-of the splits and inside the opposed sides of the coiledgspring to thus hold-or lock the coiled spring in position. Then suitable metallic strips are placed on opposite sides of the splits with the proximate edges of the strips being disposed in close, but slightly spaced relation, to the coiled spring and then-suitable wiresare passed between the splits .at spaced intervals and around the strips to hold the strips in position while the ends thereof have rivets passed therethrough which are also passed through suitable end pieces at each end of the reed. The reed in this position is then dipped into a solder bath, one edge at a time, down to a point where the solder runs between the coils of the coiled spring and between the splits and is supposed to run between that portion of the splits which is confined between the two metallic strips on each side of the ends of the splits.

It very often happens that in securing the strips on the opposed sides of the splits by the wires encircling the strips and being disposed between certain of the splits, these splits between which the tie wires are placed are pressed apart from each other to a distance greater than the spaces between the adjacent splits and therefore imperfect weaving of cloth occurs on the beat-up of the reed in the lay of the loom as the warp threads will not be spaced equally apart from each other throughout the width of the cloth being woven.

It is an object of this invention to overcome these difliculties by providing a U-shaped member with its edges flared outwardly which is adapted to be slipped over the ends of the splits after they have been positioned as above outlined to thus clampingly engage the ends of the splits and thus the necessity of securing side bars to the ends of the splits by tie wires is eliminated and 2. thus theluse .of the tiewires is eliminated and thus all portions of :the splits are arranged in equalspaoedzrelationto each other and thus "there are no wide .dents occurring throughout the length :of the reed.

.U-shaped member is preferably perforated throughout its "length to allow easy flowing of the solder into the spaces between the splits which are covered by the :U-shaped member and alsoallows :oil. and other impurities which may be presentzon the :splits to :flow out through some in" the perforations in the U-shapedmemberand thus .a more perfect soldering will take place to firmly bind the splits to each other and to also bind the U-shaped member on the ends of the splits.

Furthermore, by hayingithis U -shaped member flared outwardly at its open end, a channel is provided for reception of edges of the metallic cover which is :sllrpped thereover, which is very much more efiicient than the veryrsmall channel which is providedby the edges of the bars which have heretofore been used on each side of the .endsof the splits, and thus the possibility of dislocation of the cover or adapter member to make the reed fit a cotton type loom is eliminated,

Some of the objects of the invention having been stated, other objects will appear as the description proceeds, when taken in connection with the accompanying drawings, in which- Figure l is an isometric view of one end of a reed embodying the invention, and omitting the solder;

Figure 2 is a vertical sectional view taken along the line 22 in Figure 1 and showing the central portion of the splits broken away;

Figure 3 is an isometric view of the upper lefthand corner of Figure l, omitting the cover or adapter which is adapted to be placed thereon, and also omitting the coiled spring;

Figure 4 is a vertical sectional view similar to the upper portion of Figure 2 but showing the cover or adapter removed and showing the same after it has been dipped in solder.

Referring more specifically to the drawings, the numeral [0 indicates conventional splits of a conventional loom reed. This loom reed has near each edge thereof coiled wires II the coils of which are pressed between the splits to hold them apart from each other and suitable metallic half round members I 2 are inserted against both edges of the splits and inside the coils of the coiled spring to hold the coiled spring and the splits in locked position relative to the dents.

The loom reed is provided at each end with shaped member clampingly engages the ends of the end bars 14 and also the ends of the splits I6 and when the reed is thus assembled, one edge at a time is immersed in liquid solder to almost the top edge of the coiled spring, which causes the solder I8 to flow in between the ends of the splits I 0 which are covered by the U-shaped member and to fill the spaces therebetween and also fill or partially fill the perforations l6 and also fill the spaces between the splits encircled by the coiled springs and to encompass substantially the half-round members [2, the limit of dip being to almost the topmost portion of the coiled spring I I and owing to the surface tension of the solder, it does not have a tendency to appreciably adhere to the exterior surfaces of the U-shaped members l5 nor the coiled springs ll nor to the space between the coiled springs H and outturned flanges [1, thus leaving channels IS on each side of the splits adjacent the outturned flanges I1 into which a suitable adapter or cover member 2| is adapted to be slid. This cover member 2| is conventional. and comprises a substantially tubular member having a slit longitudinally thereof of suificient size so that the end members M and the splits It] can pass through this slot and yet be clampingly engaged by the walls of the slot in the tubular member or adapter 2!.

It is thus seen that I have provided an improved metallic loom which can be used as a silk reed without the adapter 2| or when used as a cotton reed with the adapter 2| will not only securely hold the splits in evenly spaced relation 4 but which will also securely hold the adapter 2| when the same is used and prevent its slipping ofi or becoming dislodged from the reed during operation.

In the drawings and specification there has been set forth a preferred embodiment of the invention, and although specific terms are employed, they are used in a generic and descriptive sense only, and. not for purposes of limitation, the scope of the invention being defined in the claim.

I claim:

A loom reed comprising a plurality of spaced splits and having end bars at each end of the loom reed, a U-shaped member disposed over the ends of the splits and extending throughout the length of the reed, said U-shaped member having its free edges turned outwardly away from each other to provide a channel for reception of the edges of a tubular adapter when slipped thereover, said U-shaped member having a plurality of perforations through its side walls to allow the ingress of solder into the spaces between the splits confined between the walls of the U-shaped member.
