PATENT JOSEPH B. WHITNEY, OF BROOKLYN, NEl/V YORK.

-WARPlNG-:MACHINE.

SPECIFICATION forming part of Letters Patent NO. 687,359, dated November 26, 1901.

Application filed March 30,1901.

To all whom it may concern.-

Be it known that I, JOSEPH B. WHITNEY, a citizen of the United States, residing in Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Warping-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 in the 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. 7

This invention relates to the operation of warping; and it has reference particularly to that portion of the mechanism usually employed for carrying on this operation, which comprises a creel, the condensing-reed, and the other accessories intermediate these parts.

The objects of the invention are, first, to so construct and arrange the several reeds of the mechanism that the threads will be subjected to only the minimum of turns from the time they leave the spools on the creel until they are about to be wound on the reel and that such turns as they have to make will be around smooth rounded parts, so that the abrasion of the threads will be as much as possible avoided; secondly, to provide for such an arrangement of the threads on the creel that thereby the number of spools may, without inconvenience otherwise, be increased and the capacity of said creel thus augmented; thirdly, to provide a simpler and more readily-operated form of adjustable condensingreed than is at present in use; fourthly, to provide means for imparting such a disposition to the threads as they pass through the condensing-reed that the strain which is exerted by the outermost threads on the dents of the condensing-reed as an incident to the relatively sharp turn which they make at this point will be properly distributed, and, lastly, to provide an improved form of mounting for said bars.

The invention will be found fully illustrated in the accompanying drawings, wherein corresponding letters and figures of reference indicate like parts, and wherein- Figure 1 is a top plan view of that portion Se ial N 53.589. (No model.)

of a warping mechanism in which my invention resides. Fig. 2 is a central longitudinal sectional view of the mechanism as illustrated in Fig. 1. Fig. 3 is a horizontal sectional view through the reeds on the creel, showing the arrangement of the threads as they pass olfsaid creel. Fig. 4 is a detail view illustrating a slight modification of the invention. Fig. 5 is an enlarged top plan viewillustrating the adjustable condensing-reed. Fig. 6 is a sectional view of the front portion of said reed. Fig. 7 is a sectional View of one of the reed members, and Fig. 8 is aview in front elevation of the cross-reed frame and theelevatory bar which coacts with the cross-reed to effect the separation of the threads into two sheds.

The reference character a in said drawings designates the creel, upon which is arranged in the usual manner a series of spools b. On the top of this creel are mounted a reed c and two horizontal bars (Z, preferably of glass and preferably arranged the one directly above the other. These bars may be either secured directly to the reed or separately mounted, as desired. A short distance in front of the reed c is arranged another reed e and also another horizontal barf. The said reed and bar may be supported on the creel by brackets g, or, if desired, they may be carried on a separate stand h, designed for the purpose. The reed e has twice as many dents 7;, and consequently twice as many spaces, as the reed c. The threads areled up from the spools in pairs, of which one thread passes over the lower bar (1 and the other thread over the upper bar at, and thence together through the same space between the dents 't'. After leaving the reed c the threads in each pair are separated again, each thread passing through its individual dent in the reed e. By passing the threads through the reed c in two sets, in which the threads of one are directly above the corresponding ones in the other, the width of the body of threads is reduced just onehalf, and thus the number of spools on the creel may be materially increased. This arran gement of the threads is not allowed, moreover, to interfere with the single-plane disposition thereof, which is found desirable after they leave the creel, for thebar f adjoining the reed e acts to bring them into the said disposition.

j designates a suitable support which is arranged, as usual, at a distance from the creel a. On this support is mounted a skeleton frame It, having brackets Z m n and uprights 0. At the end of said frame which is adjacent the creel is mounted the cross-reed p. In guides q, secured to the front face of this reed, work the ends of a horizontal elevatory bar r, preferably of glass, which has a down- Wardly-extending projection s, penetrating a lug t, which extends from the reed-frame, the said projection and lug constituting an auxiliary guide for the bar. Pins'u are mounted in the guides q, said pins being adapted to sustain the bar in its elevatory position and being removable, so that the bar may be lowered. In the brackets Z is mounted a horizontal cross-bar '2). In the brackets m is mounted another and elevatory cross-bar w, the same having arms 00, which are fulcrumed in said brackets. In the brackets n is journaled a revoluble cross-bar y, which is the part which the threads last engage before passing onto the reel.

z denotes a block, which is mounted upon a central rib 1 of the frame lo. Back of this block is arranged a transverse cross-piece 2. On said block and cross-piece is supported the condensing-reed 3. The block is slightly higher than the cross-piece, and their top faces are inclined parallel with the normal plane of the sheds, so as to bring thecondensing-reed into proper disposition with regard to said threads. The said reed 3 is in two sections 4, which are secured together at one end by hinges 5 and the frames of each of which may be reinforced by brass strips 5'. The pivot 6 for one of the hinges is in the form of a bolt 7, which extends down through the block z and through the rib 1, having a wing-nut 8 whereby the cross-reed is secured in place. reed-sections 4 are hinged, as at 9, to the free ends of pivotally-connected links 1.0. The pivotal connection between the links is in the form of a bolt 11, having a wing-nut 12, the said bolt penetrating a slot 13 in the frame 7c and, with its wing-nut, affording means for adjusting the reed -sections in an obvious manner.

In the uprights 0 are mounted the parting bars 14. The ends of these bars are tapered, as at 15, and are adapted to fit into correspondingly-shaped recesses 16, which, as best seen in Fig. 2, are curved and turned away from each other at their lower ends. By the arrangementjust described when the parting-bars are in position maintaining a cross in the threads the latter in tending to force them away from each other will keep them from being accidentally thrown out of place. It should be remarked that these partingbars are of a diameter which approximates the length of the dents in the condensing- The rear ends of the reed and that the one which is next to the reed is close to the same. Ordinarily, and especially where a considerable number of threads are led through each dent in the condensing-reed, there is a great strain upon the outermost dents of the reed. This is due to the fact that these threads have to make quite a sharp turn at practically the middle portions of the dents when they reach the reed, and if the dents of the reed are of delicate material, as they often must be in order to accommodate a great number of threads in a small space, they are often damaged. By therefore making the parting-bars of a diameter which approximates the lengths of the dents of the condensing-reed and bringing the adjacent one close to the reed the objec-- tion referred to is overcome, for the strain of the outermost threads is now imparted to the dents near the ends thereof instead of near their middle portions.

In order that the threads may pass from the creel to the condensing-reed without being subjected to any undue abrasion, I preferably construct said creel and also the reeds c, e, and p in arc-shaped form in elevation, so that the threads will have. practically no contact With the dents at any point. With a further view to the same object I provide the reeds of the mechanism throughout, with the excep tion of the cross-reed, with round glass dents. The above-mentioned object of avoiding the concentration of the strain of the outermost threads against relatively small portions of the surfaces of the engaged dents of the condensing-reed may be also attained by the arcshaped bar r, which being horizontal, while the threads are not so, presents to the latter a curved surface, with the consequence that each of the'outermost threads stands a little higher than its next inner neighbor. The tendency, therefore, is not only to dispose the threads in a vertical layer one after another against the engaged dent of the reed, (it being remembered that a considerable number of threads are often extended through each space of a condensing-reed,) so as to avoid the concentration of their strain on a small portion of the dent, but to also arrange the threads in their natural order and so avoid their bunching and the consequent breaking of some of them. It will be understood that any other means which tends to successively elevate the threads will also subserve the same function; that, moreover, the nearer said curved bar or other similar part is placed to the cross-reed and the greater the angle between its plane and that of the warp the more emphasized will be the desired arrangement of the threads. The bar 0 should, under the circumstances now being referred to, be removed out of contact with the threads, else it will counteract the efiect aimed at. If the bars d areso arranged on the creel that they are disposed between the planes in which are the tops and bottoms of the spools-that is to IIO say, the heads thereofthe threads will not project out free where they might possibly be caught and broken.

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

1. The combination of a creel, a reed ar ranged substantially above said creel, and bars disposed in substantially superposed disposition adjacent said reed, a plurality of threads being adapted to be extended through each space in the reed and individually over the bars, substantially as described.

2. The combination of a creel, a reed arranged substantially above said creel, bars disposed in substantially superposed disposition adjacent said reed, a plurality of threads being adapted to be extended through each space in the reed and individually over the bars, and another bar adapted to engage all said threads to effect a single-plane disposition thereof, substantially as described.

3. The combination of a creel, a reed arranged substantially above said creel, and bars disposed in substantially superposed disposition adjacent said reed, a plurality of threads being adapted to be extended through each space in the reed and individually over the bars, and said bars being arranged in a plane between those of the ends of the spools on said creel, substantially as described.

4. The combination, with the creel and the condensing-reed, of reeds interposed substantially between the spools on said creel and said condensing-reed, each pair of dents in each reed being disposed substantially at right angles to the direction in which their corresponding thread extends, substantially as described.

5. The combination, with a suitable support having a slot, of a pair of reed-sections pivotally connected at one end and carried by said support, links pivotally connecting the other ends of said reed-sections, and a bolt adj ustably securing said links together and to the support, said bolt penetrating said slot, substantially as described.

6. In a mechanism for maintaining series of threads in crossed disposition, the combination, with a suitable support, of a pair of uprights mounted on said support and having downwardly-extending recesses turned away from each other at their lower ends, and parting-bars seated in said recesses, and adapted to maintain between them the crossing in the threads, substantially as described.

7. In a warping-machine, the combination, with a suitable support, of a pair of uprights mounted on said support and having downwardly-extending recesses turned away from each other at their lower ends, parting-bars seated in said recesses and adapted to maintain between them a crossing in the threads, and a reed also mounted on said support and disposed appreciably adjacent one of said parting-bars, said parting-bar having a diameter approximating the length of the dents in said reed, substantially as described.

8. The combination, with means for maintaining the threads of the warp in substantially side-by-side disposition in one portion of said warp, of a condensing-reed disposed remote from said means and adapted to receive several threads in each of its spaces, and a device for maintaining the threads in each reed-space in superposed disposition, said device being disposed between said means and the reed and having a curved face engaging the threads, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 22d day of March, 1901.
