17 Claims.

This invention relates to combs and reeds for textile machines, and it relates more particularly to the ,construction and arrangement thereof.

In various kinds of textile machines there are used 'combs or reeds for separating, guiding, and manipulating the warp. For example, combs are ordinarily used. in warping and leasing machines, the open end of the comb being disposed upwardly to facilitate the entering of the warp, whereby the proper number of threads can be readily disposed in each dent space or split thereof. On the other hand, reeds, in which both ends of the dents are xedly secured in the frame, are customarily used for beating up the weft into the fell of the cloth, this by reason of the greater stiffness obtained when both ends of each of the dents are thus secured.

The principal object of the present invention is to provide a device of the nature of a comb or reed for use in textile machines, in the use of which facility of entering the warp afforded by a comb is obtained, and at the same time the stiffness and rigidity Aof the dents of a reed are secured.

With the foregoing object in view, the present invention contemplates the provision of a comblike structure comprising a frame, within which is mounted a series of dents rigidly xed at their lower ends and provided near their upper ends with suitable offset portions for maintaining a uniform spacing of said dents.

'I'he invention further contemplates the provision of means removably mounted in the upper portions of the structure for xedly positioning the upper ends of the dents in their spaced relationship.

The invention further contemplates, in a specific embodiment thereof, a novel form of hook reed for leasing purposes.

It should, of course, be understood that the description and drawings herein contained are illustrative merely and that various modifications and changes may be made in the structure disclosed without departing from the spirit of the invention.

The nature and characteristic features of the present invention will be more readily understood when taken in connection with the accompanying drawings forming vpart hereof, in which:

Figure 1 is a front elevation of a hook reed for leasing purposes embodying the main features of the present invention;

Fig. 2 is a fragmentary detail of a portion of said reed with the device for xedly positioning the upper ends of the dents removed from the frame;

Fig. 3 is a front elevation of a fragmentary portion of the dent positioning device, complementary to the portion of the structure shown in Fig. 2 but removed therefrom;

Fig. 4 is a transverse section taken approximately on the line 4-4 of Fig. 1;

Fig. 5 is a front elevation, enlarged, of the upper portion of one of the dents of the structure shown in Fig. 1;

Fig. 6 is a view similar to Fig. 1 illustrating a form of warp manipulating comb or reed particularly adapted for use in connection with the hook reed shown in Fig. 1 for effecting a leasing operation;

Fig. '7 is a View similar to Fig. 2 likewise illustrating a fragmentary portion of the structure of Fig. 6, but with the device for xedly positioning the upper ends of the dents removed from the frame;

Fig. 8 is a view similar to Fig. 3 illustrating a similar portion of the structure of Fig. 6;

Fig. 9 is a transverse section taken approximately on the line 9 9 of Fig. 6; and

Fig. 10 is an enlarged view of the upper portion of one of the dents of the structure shown in Fig. 6.

Referring now more particularly to Figs. 1 to 5 of the drawings there is illustrated a form of construction of a hook reed particularly adaptable for leasing. As there shown, said device comprises a suitable frame l5 having side struts I6. Disposed between the side struts I6 are the dents I1 suitably spaced and rigidly secured at their lower ends in the frame l5 in the usual manner of construction of soldered reeds, the dents l1 being thus uniformly spaced, and xedly and permanently secured in the frame l5 at their lower ends.

Each of the dents l1 there shown comprises a thin flat strip of metal which is bent over at the top as at I8 and thence extends downwardly, the bent-over tongue I9 thus provided being located in the middle of the space between the body portion of the dent and the body portion of the next adjacent dent.

A metallic block 20 preferably made of solder is positioned between the lower portion of the tongue I9 and the body portion of the dent I1 (see Fig. 5), but being located a short distance above the lower end of the tongue I9, there is thus provided a hook-like structure 2| for the engagement of certain of the Warp ends during the leasing operation.

The tongue portion I9 is also provided above the upper end of the block 2U with an offset portion 22 which extends to and bears against the body portion of the next adjacent dent The offset portion 22 is so positioned in the tongue portion I9 as to bear against the part of the body portion of the next adjacent dent which is located above the upper end of the metallic block 23, whereby advantage may be taken of the normal resiliency of the metal of the dent to permit the entering of the warp in the dent spaces of the device, yet serving normally to maintain the upper ends of the dents l1 uniformly spaced in the frame l5.v

Removably mounted on the upper portions of the frame I is a device 30 for fixedly positioning the upper ends of the dents Il after the Warp has been entered in the several dent spaces thereof. This device 3U consists essentially of a plurality of relatively short auxiliary dents 3| uniformly spaced complemental to the spacing of the main dents The preferred form of construction of this device 30 contemplates the employment of a spacing coil 32 similar in character to a spiral spring, such as is commonly used in soldered reed construction, each convolution of said coil 32 extending between adjacent dents 3|, being locked in position With respect to said dents 3| by means of longitudinal rods 33 sector-shaped in cross section, the whole being soldered together in the usual Way by a dipping process or in any other preferred manner. The dent positioning device 30 is also provided on each face thereof with suitably

shaped plate members

34 and 35, each of which is also soldered to the structure at the upper portion thereof. The plate member 34 on the front is offset inwardly so that the lower portion 36 thereof bears against and supports the front edges of the auxiliary dents 3|. The plate 35 on the rear face is also offset in a similar manner to provide a portion 31 bearing against the rear edges of the auxiliary dents 3| at the lower portion thereof, and also extends downwardly beyond the lower ends of the auxiliary dents 3|. The downwardly extending portion 31 of the plate member 35 is provided at its lower edge with a lip portion 38, which serves as a limit for lining up, in a uniform sheet, those warp ends which are not engaged by the hooklike portions 2| provided at the lower ends of the bent-over tongues I9 of the main dents |1 of the device. This will serve to prevent said warp ends from passing up to and being gripped by the offset portions 22 of the tongues I9 when the leasing operation takes place.

In the use of the device as illustrated in Figs. 1 to 5, when it is desired to enter the warp, the device 30 for fixedly positioning the upper ends of the main dents l1 is removed from the frame, whereupon the operator may readily select and placev the proper warp ends in the respective dent spaces in the same manner as is done with ordinary combs. The Warp ends will readily pass the offset portions 22 of the bent-over tongues |9 as it will be understood that the same may be easily separated a sufficient distanceA to allow the threads to freely pass, as but a relatively small amount of deiiection of each of the individual dents will be necessary for this purpose.

After the warp has been entered in the dent spaces of the structure, the device 3B for iixedly positioning the upper ends of the main dents may be replaced. As the spacing of the auxiliary dents 3| is complemental to that of the main dents said auxiliary dentsr 3|v will enter theA spaces between the upper ends of the main dents and locate the same in fixed positions. In the replacing of the positioning device 30, the downwardly depending portion 37 of the plate member 35 on the rear thereof may be first brought against the rear edges of the upper ends of the main dents I1, serving to arrange the same in a uniform plane as they are engaged by the auxiliary dents 3| passing between the dent spaces thereof. As the positioning device 3|) is pushed to its final position, the lower end 36 of the plate 34 on the front face thereof will engage the front edges of the main dents and thus prevent the displacement thereof out of the proper plane. The upper ends of the main dents will then be held in fixed positions and said dents I1 will thereafter be securely and xedly held the same as if they were soldered or o-therwise permanently secured at their upper ends as in the ordinary reed construction.

In Figs. 6 Vto 10 of the drawings there is shown another form of the device, which is adapted for use as a manipulating reed to assist in leasing operations. In this instance, the device is substantially similar to that shown in Figs. 1 to 5 of the drawings, with the exception that the main dents |`|a are somewhat differently formed.

The bent-over tongue portions are omitted, as the same are not required for the purpose to which this form of the device is to be put. There is also provided a different form of spacing means. Each of the dents |'|a is provided near its upper end with offsets 22a and 22", preferably two or more in number, as the provision of a plurality of such offsets 22a and 22b in each dent Ila Will serve to prevent distortion of the individual dents. Furthermore, the offsets of each dent are staggered with relation to the offsets of adjacent dents, so that said offsets will in each instance bear against a portion of the adjacent dent which lies in the main plane thereof, and which is resilient to a sufficient extent.

It will be noted that in each instance the dents are made of thin at strips of metal and that the spacing offsets thereof are formed rby pressing the same out of the main plane of the strip. Furthermore, the offsets bearing against sufficiently resilient portions of adjacent dents, the requisite separation of the dents for the insertion of the warp ends is quite possible. On the other hand, when the dent positioning device is in place, the dents will be held sufliciently rigid for their intended purposes.
