DIRECT WARPING-MACHINE.

Application filed April 18, 1.817.

To all whom it may concern:

Be it known that I, AUGUST F ORMON, a citizen of the United States, residing at Passaic, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Direct lVarplug-Machines, of which the following is a specification.

This invention relates to so-called direct warping machines, in which the warp, instead of being wound on a reel or the like and then re-wound onto a beam, is wound directly onto the beam, the whole warp or a considerable part of the same being treated in the machine in a single operation. In these machines difficulty has always been met with in the matter of obtaining uni.- formity of tension on all the threads of and throughout the len 'th of the beamed warp, because the tensionto which they are subjected during the warping operation has heretofore not been of a constant character. This is because after more or less material has been wound on the beam the convolutions begin to cut into the previous windings, so appreciably so that the surface of the wound body, even with layers of paper or the like interposed between succeeding convolutions, will manifest to the touch dis tinct hollows and elevations; and of course with such a formation as the surface for succeeding windings to become wound upon the latter have changing tension according as they occupy the el vations or the hollows.

My invention has for its object to elfectually overcome this difficulty and produce a warp in a direct w rping machine in which the tension will be equable throughout, and this object I accomplish by constructing the reed of the machine to be traversable longitudinally of the axis of winding and providing means to traverse the reed while the winding is proceeding; thus back and forth spiral windings will be produced, thereby preventing the cutting-in of the threads into the previously formed body of windings and the lack of uniformity of tension which, as explained. results therefrom.

My invention will be found fully illustrated in the accompanying drawmgs, where1n Figure 1 is a side elevation of the improved machine;

supporting means and the means for traversing it; and

Fig. 4 is a horizontal section on line et4: of Fig. 3.

In the frame a, in brackets Z) adjust-ably supported on a pair of cross-shafts c, is journaled the beam (Z. @neof said brackets is a housing containing gearing (shown dotted in Fig. 1) whereby the beam is driven from a transverse shaft 0 journaled in the frame and operatively connected with another shaft f, also journaled in the frame, by bevel gearing g, the latter shaft being driven through friction-drive means it from the main shaft 71, extending across-and journaled in the frame. There is a warp-driven drum j, with co-acting rollers 70, whereby a measuring means not shown) is driven, the same and the rollers being suitably journaled in the frame; and there are also the reed Z, supported, fixedly, by a bracket m projecting from the forward end of the frame, and on the frame, between said reed and the drum, a tension means designed to take up the slack in the threads when the machine is stopped and consisting of a pair of suitably journaled rollers 41. and an intermediate roller 0 supported by pivoted arms 79 and capable of up and down movement, the warp passing under the roller 0 and over the rollers 41. So much is the usual construction of direct warping machines.

A pair of uprights g are arranged, side by side, on the bracket m between the reed Z and the tension means, each having a transversely grooved head In the grooves of these heads as a guide is arranged the reed r having a slotted downwardly projecting lug s with which engages a pivot, in this case formed'by a thumbscrew t, on the upper end of a lever to fulcrumed on another thumb-screw Q) on the bracket m. The lower end of this lever has suitably jointed to it the forward end of a lever to which is fulcrumed in the frame a, standing horizontally, its rear end being suitably connected with one end of a pitman as the other end of which is connect d to a wrist-pin 7 on a gear-wheel z journaled in a bracket 2 which is bolted to the frame. This gear-wheel meshes with a pinion 3 fixed on a shaft 41. journaled in said bracket and carrying a pulley 5 around which and a pulley 6 on the shaft f extends a belt 7.

In operation, the reed is caused to traverse crosswise of the warpspecifically, length,-

consequence, the windings are deposited in a series of back and forth spirals, instead of each always 1n the same plane transverse of the axis of winding, which produces a beamed body having from start to finish a smooth uncorrugated surface and therefore avoids all possibility of the threads cutting into the windings and the consequent unequalness of tension in the warp. The motion of the reed is timed, according to its distance from the beam, so as to insure the windings being deposited as spirals, it being obvious that if the traverse of the reed were quick relatively to the surface speed of the wound body of warp the pitch of the spirals would be reduced if the spiral winding would not be altogether prevented. The desired rate of movement of the reed may be attained by selecting gearing e of the proper relative sizes. The extent of throw of the reed may be varied by shifting the fulcrum of lever u from one to another of the fulcrum holes a provided therein as shown in Fig. 3.

I find as an incident of my invention that the traverse of the reed further prevents the objectionable cutting of grooves or nicks in the rollers 91 0, the threads being caused to move laterally over the surface of each roller instead of tracking alwaysin the same path.

The extent of traverse motion of the reed r is greater than the spacing of the threads of the warp, whereby in the spiral winding of each thread on the beam it repeatedly crosses neighboring threads on both sides of it, with the result that the finished body of wound warp is in effect a single intact mass having its component parts as it were interbound or united with each other.

I place the reed r at the position shown, to wit, so that the measuring means j 70 and tension means n 0 shall be between it and the beam for two important reasons: first, so as to insure such a distance between the reed and beam that the traverse will not cause undue strain on the warp and, sec- 0nd, so as to obtain the benefit of the Incasuring means and tension means as media to insure the threads, as they wind on the beam, actually taking the traverse; each traverse impulse involves a shifting of the threads over the surfaces of the tensionmeans, measuring means and beam successively in the order named, and without these elements being interposed, with the reed far enough away from the beam to avoid unduly straining the warp even the slow traverse motion actually employed would produce in some cases too little and in others no actual displacement of the warp on the beam, according to the character of the material being warped. The acting elements 7,713 and a,

0) of the tension means do not contact with each other, which undesirably flattens the threads and leads to the production of streaks in the finished woven goods, but they simply maintain bends in the warp, so that the threads in fact roll freely over them in shifting,

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. A direct warping machine including, in combination, a supporting structure, a

beam journaled therein, a warp reed arranged in said structure, coactingparallel transverse members arranged between the reed and beam and out of contact with'each other and maintaining a bend in the warp,

and means to rotate the beam and simul-' taneously traverse the reed back and forth lengthwise of the axis of winding, whereby the warp threadswill be deposited on the beam in back and forth spirals and caused to move back and forth over the surfaces of said members;

2. A direct warping machine including, in combination, a supporting structure, a beam journaled therein, a warp reed arranged in said structure, a tension means and a measuring means arranged between the beam and reed and each including coacting parallel transverse members arranged out of contact with each other and maintaining a bend in the warp, and means to rotate the beam and simultaneously traverse axis of winding.

In testimony whereof I atfix my signature;

AUGUST FORMON.
