WARPlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 628,136, dated J uly 4, 1899.

Application filed December 20, 1898. Serial No. 699,810. (No model.) I

To all whom, it may concern.-

Be it known that I, J OHN' H. BENTLEY, a citizen of the United States, residing in Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in \Varping-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to Warping-machines; and it has reference particularly to machines of this nature commonly known-as Swiss or horizontal warpers.- V

The object of the invention is to provide improved means between the creel and the reel whereby the threads can be readily selected by the operator and whereby after being so selected they are held distinctly separated from each other throughout the warping operation.

A further object of the invention is to preserve the tension upon the various threads as nearly uniform as possible during said warping operation.

In view of the foregoing objects my invention consists in the improved warping-machine and in the combination and arrangement of its various parts, substantially as will be hereinafter pointed out and finally embodied in the clauses of the claim.

Referring to the accompanying drawings, Figure 1 is aviewin side elevation of myimproved warpingmachine and its creel. Fig. 2 is an enlarged detail View, partlyin section, of the warping-machine as shown in Fig. 1. Fig. 3 is a top plan view of the reed-carriage, showing the reeds and my improved arrangement of the parting-bars mounted thereon; and Fig. 4 is a plan view of a portion of my improved reed.

In said drawings, a designates the frame of the warping-machine, and b is its reel, which is operated in any suitable and well-known manner.

0 indicates the creel, provided with skewers cl, mounted thereon in any suitable arrangement, and with a reed surmounting it.

I f is the carriage, which supports the reeds g and h, the former being mounted upon the end of said carriage which is the 'nearer'to the beam and the latter being arranged upon the other end of said carriage, and a standard 1), which carries the parting-bars, said standard being disposed approximately midway the ends of said carriage. The carriage is operatively arranged upon the frame in any well-known manner.

The reed g is removablysecured by means of a set-screw or set-screws j in the bifurcated free end of an armk, which projects into and has a telescopic arrangement with a sleeve Z, that is fulcrumed between two lugs m, formed upon the carriage, the position of said sleeve, and consequently the arm and the reed which the latter carries, being controlled by a thumbsorew a. The parts kand Z are rendered adjustable by virtue of a set-screw o.

The standard i supports a pair of brackets 19, havingrecesses 19 19 19 formed in their upper edges and having extending downwardly from the base of the centrally-disposed recess 13 slots or grooves q, formed in their adj acent faces. It should be remarked that the recesses 132, since they are formed in an ele- ;the plane of said recesses 19 and 19 designates the parting-bars, which are mounted in the recesses and the bottoms of the slots or grooves. The parting-bars which are supported in said recesses are provided with heads 1', whichtake on the outside of the respective brackets, and the parting-bar which is arranged in the slots is somewhat ets. It will be seen that the parting-bars are sustained in such arrangement that one pair is in a substantially horizontal plane, whereas the other pair is in a vertical plane.

a indicates a rod, preferably of glass,'which is journaled upon the upper ends of fulcrumed brackets or arms e, which are mounted in operative proximity to the reed-h, said glass rod being adapted to sustain the threads when the warper is in operation in the well-known and usual manner.

The reed h is especially designed to facilitate the operation of selecting the threads which are to be kept separated by the several parting-bars. The dents s are spaced by blocks 15, which are disposed in such arrangement that when the operator desires to select threads which are to be spaced from each other by the several parting-bars said threads can be readily identified. The preferred arrangement of these blocks is that shown in Fig. 4, wherein between the end piece of the frame and the first dent and substantially midway the ends thereof is a pair of spaced blocks. Between the first and second dents and near the lower ends thereof is a single block. Between the second and third dents is another pair of spaced blocks, the upper one being near the upper ends of said dents and the lower one being in coincidence with the lower one of the first pair of blocks, and between the third and fourth dents there are no blocks. This arrangement is repeated in rotation throughout the length of the reed. The several blocks are secured to both the surfaces of the two dents or of a dent and the end piece of the reed-frame in any desired manner; but itis preferred to form them of metal and solder them in place. rangement of the blocks throughout the reed therefore consists of four parallel lines or series of said blocks. These series I have lettered as 00', .70 m and as.

The first thread passes through the first space of the reed and above the lower one of the first pair of blocks, the second thread passes through the second space and above the second or single block, the third thread passes through the third space and above the lower one of the second pair of blocks, and the fourth thread passes through the fourth space of the reed.

In selecting the various threads the opera tor depresses the warp with his hand between the creel and the reed h, whereupon the line of blocks 41: will act to divide the threads into two sets. Having thus divided the warp into two sets of threads, upon further depression thereof a subdivision of the lower one of the two sets of threads thus formed will be effected by the series of blocks 00, whereupon they may be maintained in the relative positions which they have now been made to assume by the lowermost parting-bar and by the parting-bar farthest from the reed h. Now upon lifting or raising with the hand the upper set of warp-threads a subdivision of them will also be effected by the series of blocks 00 whereupon they may be maintained in their relative positions by the uppermost parting-bar and the parting-bar which is farthest from the reed h. In other words, the arrangement of the blocks between the dents of the reed is such that one line or series of them is adapted to effect a division of the warp-threads,while the otherseries are adapted to effect subdivisions of said warp-threads. As a result of the arrangement of the threads The ar-' which has thus been produced threads 1 and 3 will be above, while threads 2 and 4 will be below, the parting-bar which is farthest from the reed 7b, and threads 2 and 3 will be kept separated from threads 1 and i by the lowermost and uppermost parting-bars, respectively. Having thus eifeeted a separation of the threads and sustained them in their various relative positions by three of the parting-bars, the operator has only to place the other parting-bar in position with threads 2 and 4 passing over it and threads 1 and 3 under it.

I-Ieretofore the number of parting-bars being confined to but two the threads of the warp were consequently divided into only two sets, and therefore the threads were in effect so close together that there was great difficulty in distinguishingthem. By my arrangement of the parting-bars, in which more than two are employed, the threads are maintained in a subdivided as well as a divided disposition. The parting-bar which is farthest from the reed is placed at a distance from the vertical pairof parting-bars for the sake of convenience in selecting the various threads as well as for mounting it in position. The parting-bar which is nearest to the reed his employed so as to bring the threads as close together as possible between said reed and the various parting-bars, as at this point it is desired they should be.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a warping-machine, the combination of the reed-carriage and several parting-bars suitably mounted thereon, a pair of said parting-bars being vertically disposed and the others of said parting-bars being situated out of vertical coincidence therewith and both sides thereof, substantially as described.

2. In a warping-machine, the combination of the reed-carriage and parting-bars suitably mounted thereon in pairs, one of said pairs being horizontally disposed and the other of said pairs being disposed vertically and between the members of said first-named pair, substantially as described.

3. In a warping-machine, the combination, with the reed-carriage, of a reed or reeds sustained thereon and parting bars suitably mounted on said carriage in pairs, one of said pairs being disposed horizontally and the other of said pairs being disposed vertically and between the members of said first-named 7 pair, substantially as described.

4; A reed provided with a series of blocks disposed in alternate spaces between the dents thereof and with other series of blocks arranged the one above and the other below said first-named series, said last-named series dents thereof, with another series of blocks arranged below said first-named series and in some of the remaining spaces, and with one or more other series of blocks arranged above said first-named series of blocks and in spaces coincident therewith, substantially as described.

6. In a warping-machine, the combination, With a reed provided with a series of blocks disposed in alternate spaces between the dents thereof and with other series of blocks arranged the one above and the other below said first-named series, said last-named series being less in number than, and disposed in some of, the remaining spaces, of several spaced and suitably-mounted parting-bars, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 19th day of December, 1898.
