COMES USE-I) IN THE TEXTILE ART.

Original application filed September 10, 1917, Serial No. 190,501. Divided and this application led January 8, 1923.

T all who/m t may concern.'

Be it known that I, HOWARD D. COLMAN, a citizen of the United States, residing at Rockford, in the county of Winnebago and St-ate of Illinois, have invented certain new and useful Improvements in Combs Used in the Textile Art, of which the following is a specification. l y

This application is a division of myV apl0 plication Serial No. 190,501 filed September 10, 1917, for patent upon a warping apparatus. The apparatus disclosed in the last mentioned application comprises a warper and a creel, the creel being especially designed to support cross-wound yarn masses of the type commonly termed cheeses The object ci the invention claimed in the present application is the production of a comb constructed in such a manner as to facilitate the operation of placing the threads in the comb in proper order, and, when a vacant space occurs in the comb upon the stoppage ci the machine, to indicate to the operative fthe location oi the cheese whose thread` is missing, thus expediting the work of piecing up broken threads,

In the accompanying drawings, Figure 1 is a. side elevation of one torm of warping apparatus with lwhich the improved comb may be used. Fig. 2 is a. fragment-al view of the comb. Fig. 3 is a top plan view of the apparatus shown in Fig. 1, with parts omitted. Fig. 4 illustrates one way in which the threads may be guided in passing from the creel to the warper.

lIn Fig. 1, the cheeses are designated a. The creel in which the cheeses are mounted may be of any suitable construction, that herein shown being` generally similar to the creel disclosed in Patent No. 1,207 ,138 dated December 5, 1916., The cheeses are rotatably supported upon spindles 1, four cheeses being carried by each spindle. As explained in the above-mentioned patent, the spindles 1 are arranged in groupsV of three, each group being i'iXed to a base (not herein shown). Each such base with its row of spindles 1 may be termed a trident.

The creel herein shown comprises two upright frames 6 and 7 which are adjacent each other at one end and separated from each other at the opposite end so as to constitute a V-shaped structure. Each of the frames 6 and 7 is composed of siX bays, each adapted Serial No. 611,213.

to support three tridents arranged one above the other. At the forward side of each bay is a hinged gate 12.

The warper, which may in general be of any preferred construction, comprises a comb 244 located in the upper portion of the warper. In; the rear of the comb 244 is a guide rod 245 (Fig. 4) for holding the lower strands out of contact with the back or body of the comb.k It desired, a rod 246 may be provided above the rod 245 to keep the topmost strands in the comb. The rod 246 may be so mounted that it may be raised to give access to the comb when thethreads from a new sert of cheeses are to be laid in the comb. Forward of the comb is a guide roll 247. Thek p- arts 245, 246 and 247 are more fully described in my application Serial No. 190,502, filed September 10, 1917.

The comb 244 is provided with teeth 244a so arranged as to indicate the proper locations for the respective threads. As shown in Fig. 2, the spaces or dents of the comb are divided into sections, there being as many sections as there are co-lumns of cheeses, and each section containing as many spaces as there are cheeses in a column. Inasmuch as there are twelve bays in the creel herein shown and four columns in each bay, the 'comb is provided with forty-eight sections, there being nine spaces in each section. The sections are differentiated from each other by making the teeth of each section of regularly increasing length', the shortest tooth being at the inner end of the' section. The space between the two middle sections is made slightly wider than the vo-ther spaces, as such middle section receives two threads.

Assuming that the creel has been supplied with tridents carrying full cheeses, the method of placing the threads in the warper comb is as follows: The operative collects the threads of the column of cheeses which is nearest the warper at, say, the right-hand side of the creel, beginning at the top of the column and drawing thethread ends down to the bottom, the threads twisting together into a bunch.

Having thus collected the threads of the four columns of the bay, the operative closes the gate 12, reaches through the gate and picks up the bunches of threads, draws the bunches of threads over to the warper, passes them beneath the guide rod 246, the lowermost thread of the bunch that comes from the column of cheeses nearest the warper being laid in the middle space of the comb and the remaining threads of said bunch being laid in the comb in regular succession toward the right. The threads of the next column of cheeses are then laid into the next section of the comb, and so on. After allthe threads from the right-hand side of the creel have been deposited in the comb, the threads from the other side of the creel are brought forward and placed in the comb, after which all of the threads are drawn down over the roll 247 into position to be connected to the warp beam B.

The correct placing of the threads in the comb 244 is facilitated by reason ofthe fact that there is an individual comb section for each bunch of threads, that therel are just enough spaces in each section to accommodate the threads in a bunch, and that the teethare of graduated length. W hen laying lthreads in the comb, the longest tooth of each section serves as a stop in positioning the bunch of threads that belong in the next adjacent section.

Threads of a bunch can be readily laid in their respective spaces in the comb, as the threads fan out or diverge from the operatives hand, the bunch of diverging threads being inclined in the same general direction as the upper edge of the comb section. If a thread be missing from a bunch, there will be a vacant space in the comb section, thus immediately bringing the matter to the attention of the operative.

Inasmueh as thethread from the lowest cheese in a column extends through the shallowest space in its section, and so on progressively, a vacant space occurring in the comb upon a stoppage of the warper indicates to the operative the location` of the cheese the thread of which is missing, thus expediting the work of piecing` up broken threads.

While I have described the comb as employed inv connection with, a certain form of 4warping apparatus, it should be under stood that the comb is capable of use with textile apparatus of various types.

I claim as my invention:

l., A warping apparatus having, in combination, a warper anda creel, said creelV Y comprising a plurality of `columns of yarn mass supports, and the warper having a comb provided with teeth forming spaces which are divided into distinct sections, there being as many sections as there are columns of yarn mass supports, and each section containing as many spaces as there are yarn mass supports'in a co-lumn.

2. A warping apparatus having, in combination, a warper and a creel, said creel comprising a plurality of columns of yarn mass supports, and the warper having a comb provided with teeth forming spaces which are divided into sections, there being as, many sections as there are columns of yarn mass supports, and each section containingv as many spaces as there are yarn mass supports in a column, the teeth of each section being of differingdengths.

3. A warping apparatus having, in combination, a warper and a creel, said creel comprising a'plurality of columns of yarn mass supports, and the warper having a comb provided with teeth forming spaces whichY are divided into sections, there being as many sections as there are columns of yarn mass supports, and eachsection containing asmany spaces as there are yarn mass supports in a column, the teeth` of each section being of regularly increasing length.

4Q A. warping apparatus having, in combination, a warper and creel, said creel oomprising a plurality of columns of yarn mass supports, and the warper having a comb .provided with teeth forming. spaces which are divided into sections, there being as many sections as there are columns of yarn mass supports, and each section containing as many spaces as there are yarn mass supports in a colunm, the teeth of each section being of regularly increasing length, the shortest tooth being atV the inner end of the section.

5. A comb for textile apparatus having teeth which are differentiated into sections by differences in the length of the teeth, the shorter teeth ofA a section beingat one end of the section.

6. A comb for textile apparatus having teeth ,which are differentiated into sections, the teeth of, each section being of graduated length, the shorter teeth ofjeach section being those which are nearest the middleof the comb.

In testimony whereof, I have hereunto affixed my signature.
