This invention relates to combs and reeds for textile machines, and it larly to a novel construction and arrangement thereof.

In various kinds of textile machines there are employed combs and reeds for separating, guiding and manipulating the warp and weft Such combs and reeds are used in various ways, in warping and leasing machines, and in looms for beating up the weft into the fell of the cloth. The reeds or combs at present in common use are usually made in two main types, in one of which the dents are held in proper spaced relationship on wooden strips at the top and bottom by means of pitch initially applied in a and in the other of which the various parts of the reed are made of metal and said parts are secured to each other by means of solder or the like.

The present invention relates to that type of comb or reed in which the dents are spaced by being disposed in the successive convolutions of coil springs. In such structures bar members are usually provided on each-side of the ends of the dents. Preferably there are also provided rods of chordalcross-section extending through the convplutions of the springs serving to position the same with respect to the sideedges of the dents near the ends thereof. After the parts are assembled as aforesaid, the same are secured to each other by causing melted solder to flow into the interstices in and around the ends of the dents and in and around the spacing springs, which solder also serves to secure and-hold the side bar members in place.

Heretofore, in the construction of combs or reeds of the character aforesaid, one of the printo insure the proper disposition of the solder in the interstices in and around the ends of the dents and in and around the coil springs employed, without at the same time having the solder extend into. the spaces between the dents where the same is not vdesired. Frequently, in the endeavor to prevent the solder threads.

molten condition,

5 Claims. (Cl. 139-192) relates more ,particualong the springs where the springs are otent- 'tirely covered or fllled in by the solder.

A further object. of the invention is to provide a comb or reed or the soldered type in which the various parts may be more readily and quickly assembled, and in which uniformity of the specing of the dents will be assured.

The nature and characteristic features of the invention will be more readily understood from the following description, taken in connection with the accompanying drawing forming part hereof, in which:

Figure 1 is a front elevation of a comb or. reed embodying the main features of the, present invention;

Fig. 2 is anenlarged section thereof taken approximately on the line 2-2 of Fig. 1; and Fig. 3 is a, fragmentary-perspective view illustrating the manner of assembly of the various parts, the solder in this case being omitted. 1

It. should, of course, be understood that the description and drawing herein areillustrative merely, and that various. changes and modifieations may be made in the structure disclosed without departing from the spirit of the invention. w

Referring to the drawing. the reed therein shownis in many respects similar to the ordinary types of soldered reeds, being provided with end struts Iii between which the dents Ii arelocated in spaced relationship. The

dents Ii are preferably made of thin flat strips of metal.

The means for spacing the dents Il comprises the top and bottomof the frame of a coil spring II. The end portions of the provision, near the dents II are disposed in the successive confrom extending into the spaces between the dents,

the spring would be left uncovered at certain points with the result that, in the use of the comb or reed. the warp would ,become .causht or jammed with respect to the coils of the spring.

The principal object of the present invention" "volutions of the spring II. As in ali',of the arrangements of this general type, the dents it are inserted from one and the same side of the spring if, so that a portion of each convolution of the spring it extends into one of the dent spaces, and then crosses over the front edge of the dent H into the next adjacent dent space. A rod ll, of chordal inserted through the convolutionsof the spacing spring ll on the sides of the dents H over which the convolutions of the spring crosses, and these parts are so dimensioned and located that the periphery of each coil of the spring ii, on that side of the spring into abarli shape in cross-section, is'

which the ends of the dents i I. are initially inserted, is'in alinementwith the isinsertedinthe spring ll thereis mounted extendingfromendtoendoftheframe.

' asssia preferablyr'of such width as to extend from the spring to the ends of the dents.

There is also provided a bar I. secured to the opposite side edges of the dent's ll near the ends thereof. This bar II is of such dimensions that the inner marginal edge i'l thereof is disposed a slight distance beyond the innermost portions of the convolutions of the spacer spring II and the other edge of the bar I. is preferably disnosedin alinement with the ends of the dents ll.

After the various parts are assembled, the top and bottom portions of the frame are dipped in molten solder, which will serve to secure the parts to each other, and also 1111 out the interstices at the ends of the dents between the bars I! and II, and in and around the convolutions of the spacer spring ii. The solder is indicated at it in Pig. 2 of the drawing. The solderis not shown in Fig. 3 of the drawing for vclarity of illustration.

By the foregoing arrangement there is provided a reed in which there will be no possibility of the warp threads passing through thedent spaces being caught in the convolutions of the spacer spring, even though the solder does not fully cover the coils at all parts, as the inner edge of the bar I is so positioned as to prevent the warp threads passing through the dent spaces from coming in contact with the coils of the spacer spring and becoming caught at these places.

Furthermore the arrangement is such that the assembly of the various parts is greatly facilitated.

The inner surface of the bar It serves as an abutment against which the successive convolutions of the' spring will contact when the parts are being assembled.

While the invention has been shown as applied to a reed of the type in which the dent spaces are closed at both the top and the bottom, nevertheless the same may be employed in other types of reeds and combs, as for example, those in which the dent spaces are open at the top to permit the ready insertion of the warp ends, and also in combs of the type in which the dents are provided with intermediately located hooks or obstructions for the purpose of effecting leasing and other manipulations of the warp.
