ATTACHMENT roa WARPING-MAOHINES.

Specification of Letters Patent.

Patented May 117, 19 21.

Application filed June 8, 1920. Serial No. 387,284.

chines which will properly guide and tension the threads as they pass from the creel to the spool and cause them to be wound upon the spool in an improved manner.

With the above and other objects in view,

the invention comprises the construction,

arrangement and combination of parts as now to be fully described and hereinafter specifically claimed. V

In the accompanying drawing forming a part of this specification,

Figure l'is a top plan view of so much of a warping machine as is necessary to disclose the invention, the upper plate of the attachment being broken away to better show the adjustable guide blocks; and

Fig. 2 is a sectional view on line 2-2 in Fig. l.

The frame of the machine consists of a trevis 10 to the opposite ends of which are attached parallel side arms 11, and an angle piece 12 which is parallel with the trevis and extends between and is supported by the parallel side arms. The angle piece supports arsed 18 through which the threads pass and which is adjustable transversely ofthe side arms, the adjustable connection being made in any ordinary or preferred manner. As shown, bolts ll pass through the reed and through elongated slots in the angle piece and are provided with wing nuts 15. It will be noted that in the present structure the reed reciprocates in unison with the trevis, so that the angle of the threads between thereed and the guide blocks never changes as the trevis moves back' and forth in front of the spool, thus eliminating the bunching and overlying of thethreads which occurs inordinary warping machines wherein the trevis only moves.

16 denotes a creel, which may be located in any desired position back of the reed, 17 threads which are to be drawn from the creel,and 18 a spool upon which the threads are to be wound. -The spool, as shown, is

ositioned infront of and arranged parallel with the trevis,

trevis for this purpose.

The attachment of the invention comprises upper and lower plates, denoted by l9' and 20,1'espectively, upright rods 21 which extend between the platesto space them from each other, a sliding bar 22 which is provided with openings through which the upright rods freely pass, adjustable guide blocks 23 whichare carried by the sliding bar, springs 24loneend of eachof which is secured to the upper plate as-indicated at 25 and the other end of each of whichis secured to the sliding bar, as'indicatedat 26, to cause said bar to be yieldingly supported from the upper'plate, and means for adjustablysupporting the lower platefrom the trevis of the *warpingmachine. The

guide blocks are adjustable from and toward each other on the sliding bar, the adjustable connection, as shown, being madeby means of bolts 27 which pass through the guide blocks and throughfelongated slots 28 in the sliding bar and are provided with nuts 29 by which the guide blocks can be rigidly secured tothe sliding bar. The lower plate is carried by a supporting block 30, bolts 31 passing through said plate and blockto secure them to'each other, which in turn is adjustably supported by atU-shaped member 32 secured to the trevis as-indicated at 33. The-front edge of the supporting block is adapted to rest against'the base of i the U-shaped member,as clearly sh0wn, and

the arms of the U-shapedmember extend rearwardly. from the-trevis and are located on either side of and "at spaced distances from the supporting block. A micrometer adjusting screw 3%, carried by'the arms of the U-shaped member and engaging a threaded transverse opening, in the supporting block, provides means whereby the sup- ,porting block may be adjusted longitudinally of the trevis, as will be obvious. As shown, the. micrometer adjusting screw is provided with a washer 35, a cross pin 36 and a holding-spring 37 by which its'posr tion in the arms of the U-shaped member is insured.

The trevis, and consequently the frame, and the reed are adapted to reciprocate as the threads are being wound upon the spool. Any convenient means may be provided to cause this reciprocation. In Fig. 2 I have suggested a slide 38 which is secured tothe The slide iis 'arranged between guides 89 andiis provided with a rack which is adapted-to be given the proper reciprocator-y actuation by means of a pinion in a well known manner. The spool is preferably fricitionally driven, as is also suggested in Fig. 2. The periphery 40 of a drum 41 journaled in ways 42 and rotated in any convenient manner is held inengagement with the thread on the spool to cause the spool to be, rotated and additional thread to be wound thereon as will .be understood. 7 A weight 43suspended, from a cord 44 which passes over a pulley 45 and is attached tothe drum as denoted at 46,

rod, as clearly disclosed, and the opposite ends of the rod are loosely and slidably carried by the guide blocks. V r

, The creel, as herei'nbefore mentioned,

be-located in any desired position behind the reed. The threads'to be wound upon the spool are first led from the creel and passed through their proper holes in' the reed, are then made to pass between the guide blocks and beneath the guide rod in 'fiat fashion, are then. led to the spool, and

are then wound upon the spool to a sufficient extent to allow the friction drive to become operative. When nowthe drum is rotated and the frame is given the proper reciprocation, the threads, it will be obvious, will be caused to wind up on the spool in flat fashion. That is, regardless of the number of threads being fed to the spool, the threads as they go on the vspool willbe side by side and will not cross each other as has heretofore been so in the case of attachments of the present character.

As shown more clearly in Fig. 2, I'arrange the spool in proper position with respect to the sliding bar so that the threads will at all times be free from slack and'under the pro er tension for winding That is, the sp'ringswhich are secured to'the upper plate andyieldingly support the sliding bar are at all times under tension. As sug gested in full and dotted lines in Fig. 2, as

the diameter of the spool becomes increased in the winding operation, the sliding bar is adapted to be drawn upwardly by the springs. l
