Hnnnnn FRAME.

Application led 0ctober14, 1922. Serial No. 594,543.

5 State of Rhode Island, have invented certain new and useful Improvements in Heddle Frames, of which the following is a specification. Y

This invention relates to an improved construction of heddle frame adapted to be used in looms employed in weaving goods Vknown in the trade as fancy lenos and ganzes, but which may be also used in weaving other open-work fabrics; and the object of this invention is to provide a heddle-frame of thisV character which is somewhat similar in its constructionA to a reed as the frame is provided with both dents and needles arranged in the frame as desired, to Weave the required pattern.

A further object of the invention is to provide a frame of this character in which dents are removably mounted therein, whereby the dents may be rearranged in the frame to change the order of needle spaces and plain spaces to produce different patterns of wea-ve in the same frame.

Writh these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a side elevation of my improved heddle frame showing the long dents permanently fixed in the frame and the rel* atively short dents as being removably secured to the frame, and needles being located in a portion only of the spaces.

Figure 2 is a perspective view of one of the shorter removable dents.

Figure 3 is a perspective view showing a portion of one of the frames in which the dents and needles are mounted, plain spaces being left for some of the warp threads in which no needles "are mounted.

Figure i is an end view partly in section of my improved heddle frame.

Figure 5 is a perspective view of one of the needles removed.

frame of special Figure 6 is an enlarged view showing laterally projecting protu-berances near the point of the needle.

It is 4found in practice in the weaving of such goods as fancy lenos, ganzes and the like, that very satisfactory results are obtained in the production of certain patterns of these goods by using a heddle design, for instance the running of warp threads of different colors, textures or sizes along with the rest of the warp threads and to weave these design threads with a plain weave instead of the leno weave, all in the same heddle frame, and to accomplish this in a simple and effective way, I have Aproduced a heddle frame having dents and needles therebetween, which is adapted to receive other additional removable dents to be placed between the needle and its next adjacent dentv to make plain spaces, the threads to be woven with the fancy weave to be passed through the needle spaces and those to be woven with the pla-in weave to be passed through the plain spaces provided by the use of my removable dents whereby both a fancy and a plain weave may be simultaneously obtained in the same frame on the different designa-ted threads, and the following is a detailed description of one means by which these results may be accomplished Vith reference to the drawings, 10 designates the usual bars into which the ends 11 of the ordinary dents 12 are permanently secured and ordinarily in weaving plain lenos the needles 13 are secured in all of the spaces between these dents, but in the construction of a heddle frame in which a plain weave is produced on some of the threads and a fancy weave on some of the threads in the same frame, I have at intervals along the frame inserted an extra dent 14 between the original dent 12 and its next adjacent needle 13 thereby providing a plain space 15 or a space in which no needle l is set.

The auxiliary dents are preferably made shorter than the other dents and in order to retain" them in the frame between the end bars 10, I have attached strips 16 and 17 to the inner edges of the bars 10 on opposite` sides of the dents l2 so that` these extra dents may be dropped into any desired place along the frame and secured therein by the positionind and securing of the bars l5 and 17 and when it is dei.. ed to change the pattern of the weave, it is only necessary to remove these auziiiarj; dents from their places and shift or re-arrange them in the frame whereby the order of the needle spaces and the plain spaces may be changed as desired, to alter the pattern of the weave and by suchzan arrangement the same heddle frame may be employed for producing a great variety of designs or patterns of weave.

in the operation ot a loom having my improved heddle frame, thc warp threads which are to have a fancy weave are passed through the needle spaces or spaces having a needle and the warp threads which are to be woven plain are ordinarily made of a color, size or texture different froni that of the other warp threads and are passed through the plain spaces or the spaces where no needles are set and then in the operation of the loom those threads in the needle spaces are woven with the leno or fancy `weave and those threads in the plain spaces are woven with the plain weave thus producing the pattern desired in the .veave.

in the construction of a frame of this character, 1 `preferably employ needles of the character illustrated in Figures 5 and (i, which are described in my co-pending patent application Serial Number t, filed March 13, i922, the construction of which greatly facilitates the action of my improved heddle frame in the weaving of lenos or ganzes of this character.

My improved heddle frame is very simple and practical in construction and effective in its operation and by its use fancy lenos or the like may be woven, and additional arp threads used in the weaving of the cloth, which are passed through the plain spaces additionally formed by the insertion of my removable dents.

The foregoing description is directed solely towards the construction illustrated, but l desire it to be understood that I reserve the privilege of resorting to allV the inechanical changes to which the device is susceptible, the invention being delined and limited only by the terms of the appended` claims.

l claim:

1. A heddle frame having a multiplicity ofspacedapart dents providing spaces for the reception of the warp threads, needles in said spaces each to act upon and forni a fancy weave on its threads.v and means in said frame whereby entra dents may be removably mounted in any desired number of spaces in said framel between a needleand the next adjacent dent, without removing any of the heddle parts.

2. A heddle frame, fixed spaced-apart dents therein, needles fixed at one end in the spaces between said dents to act upon and forni a fancy Weave of the threads, and a removable dent positioned between the needle and its normally next positioned dent to provide a space in which no needle is positioned for the recept-ion of a warp thread for plain weaving.

3. A heddle frame having a multiplicity of spaced apart dents of substantially equal length, needles located in spaces between said dents to act upon and Vform a fancy weave of the threads, and a removable dent positioned between the needle and its nor.- inally next positioned .dent toV provide a.

space in which no needle is positioned fory the reception of a warp thread for plain weaving. y y

et. A heddle frame having a multiplicity of spaced apart dents of substantially equal length, needles located in spaces between said dents to act upon and forni a fancy weave of the threads, a removable dent positioned between the needle and its normally nextpositioiied dent to provide a space in which no needle is positioned for the recep tion of a warp thread for plain weaving, and

means for retaining said removable dent in position. y l n 5. A heddle frame having a multiplicity of spaced-apart dents providing spaces for the recept-ion of the warp threads, needles in said spaces each to act upon and form a fancy vweave on its thread, and means whereby an eXtra dent may have its opposite ends removably mounted. in the upper and lower frame bars of one of saidspaces between a needle and its next adjacent dent to provide some iieedleless spaces infwhicli warp threads to be woven plain are positioned.

6. A heddle frame having a multiplicity of spaced-apart dents providing spaces yfor the reception of the warp threads, needles in said spaces to act upon and form a fancy weave on its threads, some of said spaces being provided each with a removable dent to forni extra spaces without needles whereby the threads in said spaces are woven plain, said :removable dents being shorter in length than the rst mentioned dents, and means for removably securing said shorter dents in the frame whereby they may be readily rearraiiged to change the order of the needle spaces and plain spaces to vary the pattern of the weave.

7. A heddle frame having a multiplicity of spacedapart dents providing spaces -for the reception of the warp threads, needles in said spaces each. to act upon and form a fancy weave on its threads, some of said spaces being provided each with .ii-removable dent to provide eXtra spaces without needles ioo whereby the threads in such spaces are Woven plain, and a removable strip secured along the inner edge of the frame Jfor securing the removable dents in the frame Where- 5 by they may be readily arranged to Change the order of the needle spaces and plain spaces to vary the pattern of the Weave.

8. A heddle frame having a multiplicity of alternate dents and needles iXed therein, and means in said frame for removably mounting a dent therein between a needle and its next adjacent iXed dent, said insertable dent being of a length less than the dents fixed in the frame.

In testimony whereof I aliiX my signature.
