THOMAS rnnsoorr, OF PATERSON, "Ne JERSEY, assrenon or ONE-FOURTH To JOHN" PRESCOTT AND. own-rovers T0 JAMES WAYWELL, BOTH or. PA'IERSON, new
JERSEY.
Application filed. October 11, 19 16. Serial No. 124,978.
To all whom it may concern: u
Be it known that I, THOMAS PRESCOTT a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in I/Varping-Machines, of which the following is a specification.
This invention has for its object to pro-.
vide means for preventing in the warping operation the formation of so-called stickers, 2'. 6., binding together of two or more threads as the result of their rolling around each other or their fibers becoming snarled together where the warp is condensed down to a band preliminary to depositing 1t on the reel. Such stickers are very undesirable because when the warp is put in the loom and the threads affected by a sticker approach the lease rods therein they cannot submit freely to the parting action of the lease rods, and so a tension is set up on those threads that is undue, in consequence of which an undesirable blemish or mark appears in the cloth. I accomplish the object in view by contact means to bear against the taut warp near the reel and keep the threads separated. Preferably this contact means has a contact surface impressionable by the several threads of the band of warp, and is also movable with the advancing warp, as by being a belt or apron of some fabric arranged on a suitable roller or other sliding support; but these are not indispensable, as I have found a platform or the like support which will offer appreciable contact to the band lengthwise thereof will do, regardless of impressionableness or movability of its contact surface portion, in many instances.
In the accompanying drawing,
Figure 1 is a side elevation of a fragment of a warping machine including my invention;
Fig. 2 is a plan of the attachment which I apply to said machine in furtherance of my invention; and 1 F ig. 3 is a side elevation of said attachment.
at is the frame and b the suitably driven reel, journaled therein, of a warping machine. c is the reed carriage, cl the main. and c the condensing reed arranged therein, and

Specification of Letters Patent. Patented 18, 1 917.
f the'lease rods arranged the carriage be tween thetworeeds. a I
I'place on the reed carriage between the condensingreed andithe reel what is in effect a platform overwhich thetaut'warp band moves on its way to the reel. 1 In .the present construction this platform .takesI-the following form:
Secured to the carriage is a pair of brackets g in which is journaled the series it of horizontal rollersin inclined and preferably arched disposition. Around these rollers extends an endless belt or apron z, fairly taut. The rollers and apron are arranged between the reed ev and reel and sothat the taut warp band, i. 0., the warp as condensed by the reed e, bears upon the belt, which is of suitable width to accommodate such a band, Whatever its width.
In the construction herein shown, due to thecontact member afiorded by the apron being supported by rollers, said member is free to move with the advancing warp band, being carried along by the friction between it and said warp band. It is preferable that' said member be composed of some material that is not hard, like metal, for instance, but impressionable by the threads, so that each thread will in a measure, at least, form a certain degree of impression therein; this quality, especially when combined with the movability of said member with the warp, will insure in anyicase against the threads becoming involved in the production of a sticker, each thread being held to a definite line across said member notwithstanding those influences, such as static electricity and variations in strain on the threads, which have heretofore been troublesome in cansing the threads to become connected with each other, or produce stickers. The material of said member to this end may be some woven fabric, for instance, broadcloth, though I have used even thinner fabrics with perfectly satisfactory results; in fact in the warping of certain kinds of material I have found that perfectly satisfactory results can be obtained without the contact means offering a contact surface that is impressionable at all, provided that it takes the form of a platform, that is, presents. appreciable surface lengthwise of the warp.
The term warp herein used is to be understood as limited to Warp threads before they are embodied in the cloth by weaving.
Having thus fully described my invention, Whatl claim is:
1. Means to advance under tension and wind up a band of Warp threads including a reel and means to keep separated the 0011 stituent threads of such band consisting of a platform having an approximately flat contact-surface extending toward and at one side thereof close to the reel and held hearing flatwise against the taut band, said surface being impressionable to the threads.
2. Means to advance under tension and Wind up a band of Warp threads including a reel and means to keep separated the constituent tlir'eads of such band consisting of a platform having an approximately fiat centaet surface extending at one side thereof close to the reel and held bearing flatwise against the taut hand, said platform including an apron affording said surface and movable With the advancing threads and meansto support the a ron.
3. Means to advance under tension and Wind up a band of Warp threads including a reel and means to keep separated the constituent threads of such band consisting of a platform having an approximately flat contact surface extending at one side thereof close to the reel and held bearing fiat- Wise against the taut band s'aid platform including an apron affording said surface and movable with the advancing threads and an arched series of rollers supporting the apron.
In testimony whereof I my signature.
