MACHINE FOR SIZING WARPS.

Application filed March 7, 1924. Serial No. 697,458.

To all whom it may concern:

This invention relates to machines forsizing warps or other textile sheets, as fabrics, wherein the sheet is treated with liquid size, then passed over a heated revoluble drum, and finally wound up on a beam. Heretofore on account of thediameter of the wound mass of the sheet which accumulates on the beam increasing as the treatment proceeds, the sizing was not uniformly or in other respects properly accomplished. That is, if the speed of the beam was made the proper speed for obtaining at the leading end portion of the sheet proper application of the size and the proper degree of drying thereof, then at the other or following end portion the desired application and sufficient degree ofdrying of the size would not be attained because of the acceleration in speed of the sheet which had meantime ensued, and, .on the other hand, if the speed of the beam was made the proper speed for obtaining at said following end of the sheet the desired application and proper degree of drying of the sizing liquid, then, the speed of the sheet being new at first its slowest speed, there would be a. surplus application of sizing liquid to and an undue drying thereof on the leading end of the sheet; in the first instance the following end would be unduly wet and in the second instance the leading end would be over-dried, or baked". This disadvantage was due to the drive being applied to the beam, which resulted in the sheet being drawn past the size applying means and heated drum at gradually increasing speed on account of the increasing diameter of the wound mass. According to this invention, given means to apply the liquid size to the sheet and rotating means to advance the sheet at constant speed and simultaneously dry the size thereon, together with a rotary beam on which to wind the sheet, I drive the beam onto which the sheet thus is wound through slip at constant speed, giving uniform and otherwise proper results in the application thereto and drying of the sizing liquid. Since augmentation of the diameter of the wound mass tends to cause a gradual reduction in the degree of tension of the sheet I preferably construct the rotation-transmitting means so that the degree of slip-friction it atl'ords may be varied. i

In addition to the foregoing, my inventioncontemplates certain improvements relating to the means used in these machines for applying the liquid size.

In the drawings,

Fig. l is a side elevation of the improved machine;

Fig. 2 is a plan;

Fig. 3 is a section on line 3-3, Fig. 1; and

Fig. 4 shows a detail.

a is a suitable frame and at b near the left hand end thereof in Fig. 1 is a lateral extension of the frame in which is arranged an electric motor 0 whoseshaft d carries a pinion e which drives a gear f whose sleeve 9 revolving on the shaft 72. is adapted to drive a pulley 1' through any suitable clutch j (unnecessary of detailed description) one member of which is slidable .into engage.- ment or disengagement with the other by shifting a lever A? adapted to be manually operated through a pitman 1 from a depending arm m on a rock-shaft 9?. extending lengthwise of and jonrnaled in the frame and having handles 0. Fixed to revolve with pulley i is a pinion p in mesh with the gear having fixed thereto a pinion 1' which in turn meshes with a gear 8 on a drum 1; following the usual construction there are three of these drums or cans t journaled in the frame a, two in one horizontal plane and the third in a plane below the first two, their gears 8 being connected to rotate together by transmission gearing u seen in Fig. 1 so that the two upper drums rotate counterclockwise and the lower drum clockwise. These drums are all internally heated by steam admitted thereto from a system of piping v which supplies the steam through suitable axial stufling boxes for the drums, all as usual. (The drums and substantially all the gearing described are shown housed).

The means i, p, g, 1-, s, t (when the machine is o 'ierating, that is, when the clutch is established) rotates and so advances the sheet of warp A at constant speed, the

warp extending over the two upper drums and under the third drum, in tractive engagement with all three.

On two tie rods w at the left hand end of the machine is arranged a carriage .r which it is unnecessary to describe in detail further than to say that it. includes a tail-stock 3 and a head-stock 2; it may be manually shifted lengthwise of the tie rods or transversely of the machine by turning a screw 90, which is journaled in the frame and threaded into a portion of the carriage. In the headstock is journaled a gear 2 which receives the gudgeon at one end of the beanr 3 and is adapted to have the beam made fast thereto (so as to rotate therewith) in any way, the gudgeon at the other end of the beam being Journaled in the tail-stock y; 4 is a pawl on the head-stock engaging the teeth of the gear to prevent its backward rotation. In mesh with the gear 2 is a pinion 5 which is splined on the shaft 6 journaled in a bearing 7 of the carrier .1 and also in a bracket 8 upstanding from the tie rods Q0. 9 is simply a pivoted device engaged with a grooved collar 5 of the pinion and which may be used to slide the pinion on the shaft 6 clear of the gear 2 whenever it is desired to disconnect the gear from the shaft 6. The carriage and the details I have heretofore described in connection therewith are well known in machines wherein a warp, fabric or other sheet is wound on a beam. 7

The shaft 6 carries a pulley 10 and around this pulley and the pulley 2' extends a belt 11. Thus is afforded between the rotary drumincluding means and the beam 3 a rotationtransmitting means which affords slip-friction-as between its parts z'11-10; when the machine is operatlng the mass which at:- cumulates on the beam and formed by the convolutions of the sheet A will increase in diameter (especially as it is the'custom to wind in a sheet of paper or the like to keep the convolutions of the sheet A separated), in consequence of which the beam-would tend to advance the sheet A at a constantly increasing rate, whereas the sheet is actually kept advancing at a constant rate by the drum which, as described, is rotated at constant speed; therefore the means 1011i affords the required slippage. Means is provided whereby the tension of the part of the sheet A between the beam and the nearest drum t may be kept substantially constant (since otherwise this tension would obviously decrease as the mass of windings increased in diameter). Thus I provide a stand 12 in which is movable vertically a follower 13 which forms a nut on a screw 14 that is journaled vertically in the stand and has a hand-wheel 15 for turning it, the follower being equipped with a roller 16 which bears on the upper stretch of the belt 11 and according as its pressure thereon is increased as the mass accumulates on the beam increases the degree of tractive effort existing between the belt and the two pulleys i and 10.

Assuming means (to be described) exists to apply the sizing liquid to the sheet it will be seen in view of the foregoing that the sheet is advanced and receives the sizing liquid and undergoes drying always at a constant rate, so that the sizing liquid is applied uniformly and the drying uniformly effected throughout the whole length of the sheet.

The sheet is delivered to the machine wound on a beam 17 which is jonrnaled in a carriage 18 that may be shifted transversely of the machine on two tie rods 19 by turning a hand screw 20 swiveled in the frame a and having a threaded engagement with the carriage. The sheet then passes under a roller 21 and between this roller and the nearest drum t it is treated with the sizing liquid by means known as a quetch, as follows: 22. 23, and 24: are three superposed rolls, the lowest one of which dips in the sizing liquid contained in a receptacle as will appear. The roll 22 is journaled in two stands 25 upstanding from the machine (1, whereas the other two rolls (23 resting on 22 and 24 on 23) are journaled in bearings 23 and 24, respectively, slidable vertically in the stands 25. If the weight of the two upper rolls is not sufiicient to maintain the desired pressure between each two of the set any auxiliary means (such as that. shown at 26, which is old and unnecessary to describe) may be used. The three rolls are connected by gears 27. The power to rotate these rolls in synchrony is applied to the shaft-.of the lowest roll, which shaft carries a gear 28. There is nothing novel in this quetch, per se. In a bracket 29 (Fig. 4) pivoted at 30 and adjustable vertically on its pivot by virtue of a bolt-and-slot connection 31 with the frame a is journaled a driving gear In another bracket 33 which has a slot-and-bolt connection 34 with the frame rr and which may .be adjusted tangentially of the coengaging portions of the two gears 23 and 32 is journaled a pinion 35. \Vith the. parts in the positions of Fig. 4 gear 32 drives gear 28 directly and consequently the rolls 2223- 24 each in one direction; but if bracket 29 is depressed so that gear 32 clears gear 28 and the transmission pinion 35 is meshed with these two gears by shifting the bracket to the leftthe rotation of each of the stated parts will be in the opposite direction. The sheet may be passed between either rolls. 22 a11d'23. or 23 and 24. \Vhen the sheet A is passed between the rolls 22 and 23 it will of course receive more liquid than when it is passed between rolls 23 and 24. as actually shown in Fig. 1. The directions of rotation whereby from gear 32 the rolls .may be cure by Letters Patent is: I

1. Apparatus of theclass described includ of the advance of the sheet; hence .the occasion for the mechanisinshown .in Fig 4' '0 tated in one direction or the other. a I Heretofore the rotating of the rolls was effected by-the pull of the sheet which was in many cases prohibitive, considering that the fibres have been wetted and that frequently their nature is such that they have verylittle tensile strength. Hence I rovide for rotating the rolls by making t em a part of the rotary system of the machine, the connection between them' and the. means (as the drums) by-which the sheet ispulled from them being a variablespeed rotation transmitting means. Fixed to rotate with thegear 32 is a cone 36 and journaled in a stand 37is a shaft 38 parallel with the axis of said cone and carrying a cone 39reverse to cone 36 and a gear 40 in mesh with the gear 8 of the nearest drum t. Around these two cones extends a belt 41, 42 being a belt shifter having forms 42" engaging the two stretches of the belt andhavmg tapped into it a manually revoluble screw 43 which is suitably journaled in the frame a. When the belt is shifted the speedof rotation of the gear 32 and consequently of the rolls will be changed Thus'the' rolls are driven by the. rotary means including the'drums or cans, instead-of by the pull of the sheet A which is thus saved undue strain, and any desired tensioliof said sheet may be attained by adjustment effected at 43.

' vThe sizing liquid is contained in a trough or receptacle 44 carried'by two vertical rods 45 which are guided in hangers 46' of the frame '0. These rod shave connected to them curved links-47 which are pivoted to the ends 'of arms 48' on a horizontal shaft 49. journaled in the hangers 46 and having a handle 50. When the shaft is by the handle. turned from the position in Figure 1 to the horizontal position 'inFigure 2 the trough will be, elevated to a position where.

the lower roll will dip into the sizing liquid 51 contained in the trough, the pivotingpoints between the links 47 and'arms 48 passing over the shaft 49 until the links impinge against'the shaft and the parts come. to rest with the trough elevated. The. trough can by a reverse movement of the shaft be quickly lowered for replenishing its supply of liquid, and withdrawlng theliquid from the lower roll.
