OF SOUTH HADLEY FALLS, MASSACHUSETTS, ASSIGNOR OF ONE- OF BONDSVILLE, MASSACHUSETTS.

WARP-PRINTING MACHINE.

Specification of Letters Patent.

Patented May 2, 1916.

To all whom it may concern Be it known that I, GEORGE H. VVINSLOW, a citizen of the United States of America, residing at South Hadley Falls, in the county of Hampshire and State of Massachusetts, have invented a new and useful Tarp-Printing Machine, of which the fol lowing is a specification.

My invention relates to improvements in machines for printing warp, used in the manufacture of cloth or fabric of different kinds and grades, and consists of certain peculiar means and mechanism, arranged together and combined in a single organization, for sizing, partially drying, printing, drying, steaming, again drying, and winding on the loom-beam ready for drawing-in, the yarn or threads which constitute a warp, all as hereinafter set forth.

This machine is naturally divisible into six sections which may be briefly outlined as follows, beginning at the rear end of said machine:

Section 1 comprises an apparatus for delivering and rewinding the gray or backing-cloth.

Section 2 comprises an apparatus for sizing the yarn or threads, which eventually become a warp, and which for the sake of convenience will hereinafter be referred to either by the latter term or as warp-units, said apparatus consisting of a rack for holding a suitable number of section-beams, a leasing-reed for properly placing or guiding the warp for printing, a size-box and rolls for sizing the warp, and a drying cylinder for partially drying the warp, the warp-units being caused to adhere to each other in their passage through this section, so that the warp is in condition to be printed.

Section 3 comprises printing mechanism, and a drying cylinder for the gray, which cylinder partially dries the warp at the same time the gray is dried for rolling up or rewinding by the section 1 apparatus.

Section 4 consists of one or more cylinders around which the warp passes to be thoroughly dried before going to the next section of the machine.

Section 5 consists of a number of drying cylinders inclosed in a box-like structure, such cylinders, and the other drying cylinders as Well, being heated in the interior by steam under pressure, and the inclosing structure being supplied with free steam at a very low or atmospheric pressure. There is also a drying cylinder situated outside of the aforesaid structure or box, which completes the drying of the Warp before it passes to the next section.

Section 6 comprises measuring rolls, splitting-rods, an expansion comb, draft rolls, and a device for winding the warp on the loom-beam or for rotating said beam for that purpose.

In addition to the above-mentioned sections there are the necessary driving mechanism, steam appliances, and other elements which are required to render the machine complete and practicable, and as will be more particularly noted in due course.

Heretofore various unsuccessful attempts have been made to produce a printed warp which, when woven into cloth, discloses or presents the same pattern on both sides of the fabric, it having been necessary to employ different machines at different times for doing even the imperfect work that results in the imperfect product. The several operations, by the old means, included siZ- ing the warp, drawing-in, placing the warp in a loom to weave threads across it at certain intervals for the purpose of retaining the warp-units in place for printing, removing the warp from such loom and printing, again drawing-in, and placing said warp in said loom the second time for weaving. at which time the threads that were first woven in having to be taken out as they are reached during the weaving process, which caused imperfect or defective places to appear in the cloth, and a loss of production by the stopping of the loom for this purpose. With my machine, whereby special means are provided for sizing and partially drying the warp before printing the pattern thereon, for then printing and dry ing, and for afterward steaming to set the colors, in one run or operation, the warp finally being wound on a loom-beam, after a last thorough drying, I overcome the serious objections pointed out above and consequently very materially decrease the cost of production, increase the product and produce a warp with which a perfect fabric can be manufactured, and this is the primary object of my invention.

It may be well to observe at this point that by conducting the warp from the size box directly to and over a steam-regulated cyl inder, provided for the purpose of partially drying said warp before it passes over the engraved rolls for printing a pattern on the same, said warp is prepared to take the color in such a manner that said color thoroughly penetrates said warp, and thereby produces a perfect pattern on both sides of the warp or warp-units, in consequence of which if one of such units rolls during the weaving process it does not pro duce a break in the pattern. The great value and importance of this feature cannot be overestimated.

A further object of my invention is to prevent the size or gum on the warp from adhering to the printing-roll or rolls, as it would do were it not that said warp, in being partially dried or dried on one side so as to leave the other side damp and thus enable the color to strike through the warp units and thoroughly penetrate the same,

- passes with its dry side next to said roll or rolls. Still another object is so to prepare the warp and set the color therein that it will not run or bleed in finishing the woven fabric. This obviates the necessity of steaming the cloth after it is woven.

It is to be understood that the term color is here used in its broad sense, and signifies any single color or shade or any combination of colors of shades or both.

Other objects and advantages will appear in the course of the following description.

A preferred form of embodiment of the invention, whereby I attain the objects and secure the advantages of the same, is illustrated in the accompanying drawings, and I will proceed to describe the invention with reference to said drawings, although it is to be understood that the form, construction, arrangement, etc., of the parts in various aspects are not material and may be modified without departure from the spirit of the invention.

In the drawings, in which like numerals designate like parts throughout the several views, Figures 1, 1" and 1 together constitute a side elevation of a machine which embodies the invention as aforesaid; Fig. 2, an enlarged front end elevation of said machine, showing section 6 and the outside of the drying roll of section 5; Fig. 3, an enlarged front elevation of the lower portion of the steam-box of section 5, the front of said box being removed in order to show the cylinders and other members within; Fig. 4, a rear elevation of the printing mechanism of section 4, the central portion of the rear side of the color box being broken away; Fig. 5, a front elevation of the sizing mechanism and other elements of section 3,

a part of the front side of the size box being broken out and portions of some of the rolls being broken off in order to show other members behind; Fig. 6, a top plan of the leasing and adjusting reeds; and, Fig. 7, a detail in elevation of the right-hand end portion, as viewed from the front, of the adjusting reed.

In Fig. 1, the side of the steam-box, which is next to the beholder, is omitted to disclose fully the interior of such box and its contents, and one of the cylinder connections is shown in section, thus bringing clearly into view the steam passage in and through such connection. The directions of moving parts and members are indicated by arrows.

Situated approximately in the center of the machine lengthwise is a printing-mechanism frame 1. Supported by one side of the frame 1 is one end of a shaft 2, the bearing for the other end of said shaft not being shown. Mounted on the shaft 2 are a pulley 3, a sprocket-wheel 4, and a pinion 5. Power from any suitable source is applied to the pulley 3, and it is from this point that the entire machine is driven. Power is transmitted to all parts of the machine, except to the printing mechanism which is driven by the pinion 5, through the medium of the sprocket-wheel 4, a sprocket-chain 6,aseries of sprocket-wheels 7, countershafts 8 and sprocket-chains 9, and other driving members hereinafter more particularly pointed out. There are five countershafts 8, and the middle one is driven by the sprocketchain 6 and which in turn drives the other four. All driving and driven parts are so timed that at no place does any undue strain come upon the warp.

The numeral 10 designates the warp.

A suitable hanger bearing 11 is provided for each end of each countershaft, such bearing being secured to the upper framework of the machine, which is represented at 12.

Depending from the framework 12, near the front end thereof and on each side, is a bracket 13, the rear end of the horizontal arm of such bracket being attached to a steam-box 14. Back of each bracket 13 and in the rear of the transverse center of the machine is a U-shaped bracket 15, that depends from the framework 12 and has a horizontal cross-piece 16 over the bottom part of said bracket that connects the perpendicular parts thereof at their bases. At the rear end of the machine on each side are two uprights l7 and 18.

J ournaled in a bearing 19, on the front of each of the brackets 13, is a hollow trunnion 20 of a steam-heated cylinder 21. This cylinder is associated with the steam-box 14 and a series of cylinders 22 in such box. Journaled in a bearing 23, mounted on the horizontal member of each bracket 13, is a trunnion 23 of a guide-roller 25. J ournaled in a bearing 26, on the front of each bracket 15, is a hollow trunnion 27 of a steam-heated cylinder 28, and journaled in a hearing 29. on the rear of said bracket. is a hollow trunnion 30 of a steanrheated cylinder 31. The cylinders 21, 22, 2S and 31 are for drying purposes, and the last-mentioned cylinder is the one which partially dries the warp as the latter passes over the same, instead of effecting the complete drying of a moving element as do the two outside cylinders "21 and 28, for which reason said cylinder 31 may be termed the half-drying cylinder. A guide-roller 32 has each of its trunnions 33 journaled in a bearing 34 mounted on the bottom horizontal part of each bracket 15, and a guide roller 35 has each of its trunnions 36 journaled in a bearing 37 mounted on each member 16. Two bearings 38 are provided on the back of each bracket 15 for the trunnion 39 at each end of a guide-roller 40, and a trunnion 41 at each end of a guideroller 42. The roller is above the roller 42. A hearing 43, on the back of each upright 17, supports a trunnion 44 at one end of a guide-roller 45, and a similar bearing, on the back of each upright 18, supports a trunnion 44 at each end of a guide-roller 46.

A system of steam pipes is provided for heating the several drying cylinders and other parts of the machine where heat is required and for supplying free steam where it is needed, and the live-steam pipes of such system are designated by the numeral 47, and the exhaust-steam pipes by the numeral 48. Steam from any suitable source of supply is introduced at 49, Fig. 1, into the live-steam pipes 47, and the exhaust steam escapes from the pipes 48 at the point 50. in said view, or is led away through other pipes (not shown) from said point. The pipes 47 are supplied wherever necessary with valves 51, and safety-valves 52 are provided at such points as may be necessary or desirable. Livesteam enters the half-drying cylinder 31 at 53, it enters the cylinder 28 at 54, and the cylinder 21 at 55. The exhaust steam escapes from the aforesaid three cylinders at the end of each which is opposite to that where the live-steam enters.

\Vithin the steam-box 14 is a pair of standpipes 56, and into one of these the livesteam enters at 57, and from the other the exhaust steam escapes at 58, Fig. Livesteam enters the steam-box 14 at 59, and exhausts through a pipe which leads out of said box at the top and upwardly. On the front and back of each stand-pipe 56 is a series of brackets 61 for the support of the hollow trunnions 62 at the corresponding ends of the cylinders 22. Each bracket 61 has a passage 63 therein which opens at one end into the stand-pipe 56, to which said bracket is attached, and at the other end into the open terminal of the trunnion (3:2 journaled in said bracket.

Live-steam entering the right-hand standpipe 56, at 57, rises in said stand-pipe, passes through the several brackets 61 attached to said standpipe and enters the cylinders 22. From the cylinders the steam escapes through the brackets (31 at the opposite ends of said cylinders into the stand-pipe 56 on the other or left-hand side. and escapes from said stand-pipe at In this manner and by this means the cylinders are heated to the necessary degree of temperature.

Each of the cylinders 22 is provided at one end with a gear 64. Two of the gears (34 on the front are driven in opposite directions by a pinion (35 wh ch is secured to a" shaft 66 that is suitably jonrnaled in the steam-box 14-. Secured also to the shaft 66 is a sprocket wheel GT. and a sprocket-chain GS drives said sprockct-wheel from one of the sprocket-wheels T on the second maintershaft S. the conntershaft S at the front end of the nnchine being considcred as the first. The upper gear 64 which is in mesh with the pinion G3, also in m sh with the two upper rear gears (34 and so drives them both in the direction opposite to that in which the first-mentioned gear is driven by said pinion. The remaining gears (34 in the train are in mesh one with another on opposite sides of the vertical plane between the axes of the stand-pipes 56, so that each gear below and on the opposite side relati e to the next adjacent gear above is driven by the latter in the opposite direction thereto, commencing with the second front gear frointhe top.which is driven by the 1 second rear gear from the top. By this arrangement is maintained or secured. the feed for the warp 10 in the steam-box 14, which said warp enters at 9 and passes directly to the lowermost front cylinder 22, then takes a serpentine course over and under or par- Iially around the cylinders and finally after passing over the uppermost cylinder leaves said he); at 70.

The printing mechanism consists in part of a felt -covered cylinder 71 which is mounted on a shaft 72 that is journaled at each end in a bearing lock 73 arranged to slide vertically in a slot 74 in each side of the frame 1. as it is called, 75, is required to prevent the warp 10 from coming into direct contact with the felt surface of the cylinder 71. The gray 75 starting from a roller 76, upon A hacking-cloth, or the gray which said gray is wound, passes upwardly 1.

through a series of tension bars 77 to and over the guide-roller then forwardly to and over the guide-roller 42 and downwardly under and over two spreading bars '78, thence under the cylinder 71. and up and over the drying cylinder 98 to a guideroller 79. next upwardly and rearwardly past the guide-roller 32 and in contact therewith and over the guide-roller 40 to the guide-roller 46, and finally downward through a series of tension bars 80 to be wound on a roller 81. The roller 76 has a shaft 82 which is journaled at each end in a bearing 83 on the back side of the corresponding upright 17. The tension bars 77 are attached at each end to one of the uprights 17, on the back side thereof, while the tension bars 80 are attached at each end to one of the uprights 18. two of said last-mentioned bars being in front and the other, which is the middle one in this case. being behind the uprights 18. The guideq'oller 79 has a trunnion 84 at each end which is journaled in a bearing 85 located at the lower front corner of each bracket 15. The spreading bars 78 are attached at each end to the underside of one of the brackets 15. A bar 80. having each end attached to one or" the uprights 17, assists in supporting the lon return reach of the gray, such bar being located above the roller -15.

The rewindingi' mechanism, for the gray 75. consists of a frame 87 having mounted therein a friction roller 88, a holding bar 8!) at each end, and a latch 90 alsO at each end. together with means for driving said roller. The roller 88 is mounted on a shaft 01 each end of which is journaled in the frame 87, as indicated at Each bar 89 has its base pivoted at to the contiguous end of the frame 87. and each latch 90 has its front end pivoted at SH to the upper part of sucn end of said frame. Each latch is adapted to close over the top of the associated bar 89, when the latter is in an upright position. and to retain such bar in such position. lVhen held in normal position by its latch 90. the bar 89 at each end of the frame 87 forms with the adjacent portion of said frame a vertical slot 95 in which is received the protruding terminal of a shaft 06 on which the roller 81 is mounted. The roller 81 and the couvolutions of the gray 75 thereon rest on the roller 88 and as said roller 88 is rotated the members above are also rotated, by reason of the existing frictional contact. and in this way the gray is rewound after having served its purpose. The roller 88 is driven in the proper direc tion to rewind the gray by means of a pulley 07 secured to the shaft 91. a. pulley 98 secured to the rearmost countershaft 8, and a crossed belt 99 which connects said pulleys. As the size of the roll above the roller 88 increases, the shaft 96 moves upwardly in the slots provided for it, and when it is desired to remove such roll, each latch 90 is swung upwardly out of engagement with the associated bar 89. the latter is swung downwardlv and rearwardly on its pivot 93, and said roll is taken out of the frame 87.

In passing around the drying cylinder 28, the gray 7 5 is dried. This is done to prevent the gray from mildewing after being rewound on the roller 81. The dampness,

which the gray receives and which is removed by the cylinder 28, comes from the color applied to the warp during the act of printing. Next in order forward of the gray-handling apparatus or mechanism is a rack 100 for a series of section-beams 101 from which the warp 10 starts. The beams 101 have shafts 102 which are journaled at each end in bearings 103 mounted on the frame 100, and each of such beams is provided with a weight 10% and a rope 105 to form what is commonly known as a dragrope tension. At 106 are shown a plurality of guide rods for the warp from certain of the beams 101. such rods being carried upon elevated parts of the frame 100.

In front of the section-beams 100 is a leasing-reed 107, and next in order. when the same is required. is an adjusting reed 108. The reeds 107 and 108 are supported on two horizontal rods 109 which extend rearwardly from a sizeboX 110. Each rod 10.) has a vertical support 111 for its rear end. The leasing-reed 107 is of ordinary construction. and the objects of the same are to retain the warp-units in position for printing, and for making the weavers lease on the loom-beam.

The adjusting reed 108, which is of special construction as will presently more fully appear. is for the purpose of accurately guiding the warp-units when a printingroll, such as is represented at 112. is provided in the printing mechanism with an engraved surface designed to print stripes on the warp. By means of the reed 108 the warp-units can be adjusted with absolute accuracy to fit the spacing of the roll 112 or the stripe engravings thereon. This reed is also equipped with an adjusting device for guiding the selvage to the printing-roll. when a. trade-mark is to be printed on such selvage. The adjusting reed 108 is capable, by reason of the construction of its supports as described below, of angular adjust ment on the rods 109 and relative to the reed 107, and of longitudinal adjustment.

The reed 108 is slidingly mounted in a reed-case 113. The case 113 is provided at each end on the bottom with a horizontal plate 111 which has a longitudinal slot 115 therein. An eye-bolt 116 is fitted to slide on *ach rod 109. and such bolt passes upward through the slot 115 in one of the plates 114. A thumb-nut 117 is screwed on to each eyebolt 116 above the plate 114 through which said bolt passes, and when said nut is tightened said plate is forced tightly against the rod 109 below and so firmly secures the adjacent end of the reed-case 113 to said rod. This result is made possible by reason of the fact that not only the shank but also the adjacent portion of the eye of each eve-bolt 116 is receivable in the slot 115 provided for such bolt. Upon loosening the thumb-nuts 117, the case 113 with the reed 108 thereon can be adjusted forward or backward at either or both ends on the rods 109, the eyebolts 116 sliding on said rods and the plates 114 sliding also on said rods and in relation to said bolts. The more the reed 108 is moved out of a vertical plane which is parallel with the vertical plane of the reed 107,

the closer together will the warp-units" which pass through said reed 108 be brought. and, conversely, the more nearly said reed 108 is brought into parallelism with said reed 107 the greater will be the separation between said units. In this connection attention is called more particularly to Figs. 5, 6 and 7.

The reed 108 and its case 113 may be adjusted longitudinally by the means just described, and said reed may be adjusted longitudinally in said case through the medium of a screw 118 and a thumb-nut 119. The screw 118 passes through one end of the case 113 and is attached at its inner terminal to the adjacent end of the reed 108. The thumb-nut 119 is mounted on the screw 118 outside of the case 113, and is held against axial movement by means of two dogs 120 which are attached to the adjacent end of the case 113, as best shown in Fig. 5. Upon turning the thumb-nut 119, the reed 108 is actuated in the case 113, through the medium of the screw 118, either to the right or to the left, according to the direction in which said nut is turned.

A selvage reed 121 is slidingly mounted in the reed case 113 at the top and adjacent to one end of such case. The reed 121 is actuated for adjustment by means of a screw 122 which has its inner terminal tapped into the base member of said reed, and is prevented from reciprocating by a flange 123 on said screw. said flange being held against axial movement by the adjacent end of the frame 113 and a dog 12-1 secured to said end. The purpose of the reed 121 has already been explained.

In order to prepare the warp for printing and for weaving after it is printed, it is necessary to apply thereto size or gum of a suitable character, and to this end the boX 110 for such size or gum, together with the other parts and members specified below, is provided. The size in the box 110 is heated by means of live steam which enters said box at 125. Mounted within the box 110, below the level of the size therein, is a roll 126, and in front of said roll is a pair of under squeeze-rolls 127, and above these a pair of upper squeeze-rolls 128. The rolls 127 have shafts 129 journaled, one in front of the other. in the sides of the box 110, while the rolls 128 have shafts 130 which are journaled at each end at the bases of two vertical slots 131 in the upper edge of each side of said box. The rolls 128 bear on and are driven by the rolls 127 below. A guideroll 132 has its shaft 133 journaled at each end in a projection 131 that extends rearwardly from each side of the box 110, and a guide-roll 135 has its shaft 136 journaled at each end in the top of each side of the box, said last-mentioned roll being in front of said first-mentioned roll. The side of the box 112 shown in Fig. 1 is broken away to show in full the adjacent end of the roll 126.

The warp 10, after leaving the reed 107, and the reed 108 if present, passes forward and downward over the rolls 132 and 135 to the roll 126, which latter is below the surface of the size in the box 110, then under said last-mentioned roll and upwardly and forwardly between the rear squeeze- rolls 127 and 128 and the front squeeze- rolls 127 and 128. The warp is saturated with the size during its passage beneath the roll 126, and the surplus size is squeezed out of said warp by the rolls 127 and 128.

A shaft 137 is journaled beneath the box 110 near the front end, and this shaft has secured on one end thereof a sprocketwheel 138, and on the other end a gear 139. In mesh with the gear 139 is a gear 140, and in mesh with said gear 140 are two gears 141. The gear 140, which is an intermediate gear, is loosely mounted on a stud 142 that projects from the side of the box 110 that is im mediately adjacent to this and the other gears and outside of which such gears are located. The gears 141 are secured on the ends of the squeeze-roll shaft 129 which protrude from the aforesaid side of the size-box. The sprocket-wheel 138 is driven by a sprocketchain 113 from a sprocket-wheel 144 secured on the fourth countershaft 8, which is above the size-box.

As the squeeze-rolls 127 are driven, by means of the mechanism provided for that purpose, the squeeze-rolls 128 are actuated and the warp 10 is drawn through the box 110. The warp 10 passes out of the box 110 over the front of the forward squeeze-roll 128, and is then in a thoroughly sized condition, with the warp-units adhering to each other. From the size-box the warp 10 passes upwardly and rearwardly to the half-drying cylinder 31, over the same, and downwardly and forwardly to the cylinder 71. The heat of the cylinder 31 is so regulated that in passing over said cylinder the warp is dried on one side, that is to say, on the side which comes in contact with said cylinder, while the other side of said warp remains in a damp condition whereby it is possible for the color, which is subsequently applied to the dry side, to strike through and thoroughly penetrate the warp-units, with the result that the pattern printed thereon shows alike on both sides of the cloth woven with said units as the warp thereof. Besides this very important feature or result emanating from the presence of the half-drying cylinder, there is another advantage, which is this, that the size on the side of the warp that comes next to the printing-roll or rolls is dry, hence does not stick to such roll or rolls.

The printing mechanism here shown includes only one printing-roll 112, but as is well understood more than one such roll may be employed. The frame 1 carries in addition to the printing-roll 112 and the roll 71, a color box 145 with a furnisher-roll 116 therein, said box being mounted on a pair of brackets 2 0 extending inwardly from said frame, and said furnisher-roll being in contact with the engraved or printing roll above. The furnisher-roll 116 has a shaft 149 which is journaled in the ends of the box 145. and is driven by a gear on said shaft and a gear 231 on the engraved-roll shaft 152 from the latter shaft. This roll 146 transfers the color in the box 145 from such box to the engraved roll 112 and keeps the latter filled or supplied. A doctor 150, of usual construction, is mounted in the frame 1 and arranged to act on the roller 112 to remove the surplus color therefrom. The doctor 150 is mounted on a rod 151 which is journaled in the sides of the frame 1. The terminals of the shaft 152 are supported on carriers 153153. as best shown in Fig. 1. A pair of vertical screws 154 is provided for the carriers 153. These screws: are supported on the front terminals of a pair of weighted arms or levers 1 18. The levers 148 are mounted, inside of the frame 1, on a rod 147 supported in said frame. Two vertical screws 156 are tapped into and through a pair of caps 157 which extend over the frame slots 74, and said screws bear at their lower ends on top of the bearingblocks 73 in said slots to retain said blocks. the shaft 72 which is journaled therein. and the cylinder 71 securely in position except when it is desired to elevate said cylinder. In the latter event. the screws 156 are turned in the direction to raise them so as to permit the blocks 73 and the members supported thereby to be elevated. As a means for raising and lowering the cylinder 71. a shaft 158, an arm or lever 159, a ratchetwheel 160. a pawl 161. a detent 162, and a pair of chains 163 are provided. The shaft 158 is journaled in suitable hearings on top of the frame 1, and the ratchet-wheel 160 is secured on said shaft. The lever 159 is loosely mounted on the shaft 158 and carries the pawl 161 which engages the ratchet-wheel. The detent 162 is pivoted at 166 to one side of the frame on the inner face thereof, and is adapted to hold the ratchet-wheel when released by the pawl. The lever 159 extends rearwardly from the shaft 158. Each chain 163 has its upper end fastened to a collar 164 which is secured on the shaft 158, and

its lower end attached to a collar 165 which is loosely mounted on the shaft 72 adjacent to one end of the cylinder 71. \Vhen the blocks 73 are released by the screws 156, the shaft 72 with the cylinder 71 can be raised by moving the lever 15.) up and down to e11- gage with the pawl 161 one tooth after another of the ratchet-wheel 160, and so rotate the shaft 158 and wind the chains 163 on the collars 164. The lowering of the cylinder 71 is effected by throwing the detent 162 forward to release the ratchet-wheel.

The roll 112 is driven by means of a gear 17'.) on the shaft 152. an intermediate gear 180 loosely mounted on a stud 181 that is set in the face of the adjacent frame side. and the gear 5. The gears 179 and 231 are on opposite terminals of the shaft 152. The cylinder 71 is actuated by the gray and the warp 10 and the frictional contact of the parts with the roll 112. The cylinder 28 is actuated by the gray and warp. and the latter alone rotates the cylinder 31. The roll 112 and the cylinder 71 revolve, of course, in opposite directions.

The gray 7 5 passes under the cylinder 71 in contact with the surface thereof, and the warp 11), after leaving the half-drying cylinder 31, passes under said cylinder 71 in contact with said gray. and travels with the latter up. over and partly around the drying cylinder 28 to the guide-roller 79. thence rearwardly to the guide-roller 32. At the guide-roller the gray 75 and the warp 10 part company, the former continuing rearwardly over the guideroller 10, and the lat ter passing upwardly over the guide-roller 35, and then forwardly to a drying cylinder 167. Tn passing over the drying cylinder 28 on the gray 75. the warp 10 is dried sufficiently to prevent it from marking off or smearing the rollers 7 32 and 35 which it contacts with on the way to the cylinder 167. The warp is between the rolls 79 and 32 and the gray, as it will be seen must necessarily be the case when it is remembered that the warp and gray turn rearwardly after passing over the cylinder 28 with the gray between said cylinder and said warp or on the inside.

Forward of the frame 1 is a frame 168 which has a bearing 169 for a hollow trunnion 170 at each end of the cylinder 1.67. and a bearing 171 for a hollow trunnion 172 at each end of a steam-heated cylinder 173. The cylinder 173 is behind the cylinder 167. Live-steam enters the cylinder 167 at 174 and exhausts at the opposite end of said cylinder or through the opposite trunnion. and live steam enters the cylinder 178 at 175 and exhausts through the opposite end thereof. A guide-roller 176 is mounted on a. shaft 177 which is journalcd at each end in one side of the frame 168 near the rear end thereof. The live-steam pipes 47, which supply steam to the cylinders 167 and 173. are equipped with a steam-regulator 176 for the control of the pressure in said cylinders.

The drying cylinder 167 is driven by means of a sprocket-wheel 182 secured on one of the trunnions 170, a sprocket-chain 183, and a sprocketwheel 184 secured to the counter-shaft 8 above said cylinder. The drying: cylinder 173 is rotated by the warp in passing over the same.

The warp 16 passes down over the front of the drying cylinder 167 and under the same in a rearwardly direction, then up over the drying cylinder 173 and down behind and under the guide-roller 176, and thence forwardly beneath said cylinders to the steambox 14 which it enters at 69. The printed warp is thoroughly dried by the cylinder 167, and is thus made ready for treatment in the steam-box 14. In taking its tortuous course through the steam-box 11 in contact with the cylinders 22, the warp 10 is subjected both to the heat of said cylinders and the steam in said box: with the result that the color or colors in said warp are set in a most perfect and lasting manner. The steam in the box 11 is at low pressure, while that in the cylinders is at high pressure, and the warp in its course at this time is first dampened or steamed on both sides, and then. upon arriving at the lowermost cylinder is subjected to the heat thereof applied directly to one side of said warp. Next this side of said warp is exposed to the steam in the box and the other side is brought into contact with the second cylinder 252 in the direction taken by the warp, and these alternate double exposures occur until the warp leaves the uppermost cylinder 22 and passes out of the box through the opening! 70, the last exposure in said box being to the steam therein on both sides of the warp. l pon emerging from the front of the steam-box 14. the warp 10 passes forward to the drying cylinder 21. \Vhile in contact with the cylinder 21, which the final drying cylinder, the warp 10 is thoroughly and COYIiPlQtQlV dried, the steam which was taken up thereby in said box being driven entirely off. It is by this means and in this manner that not only is the required setting of the color obtained or produced, but also the final drying which obviates any liability to mildew on the part of the warp after being; wound on the loombeam.

The warp 10 travels rearwardly and upwardly under and with the cylinder 21. a ftcr passing; orer the upper and front portions thereof, and upon leaving said cylindcr passes to the guide-roll '25 and over the same. From the roll the warp 10 drops to a measuring-roll 185, and then moves forward through the sixth or front section of the machine to a loom-beam 196 which is mounted at the very front end of such sec tion and machine.

The front section consists of a frame 187, and the measuring roll 185, a second measuring-roll 188. two splitting-rods 189, an expansion comb 190, and draft rolls 191, 192, 193 supported by said frame. Each of the measuring-rolls and 186 has a trunnion at each end or a shaft UM for which is pio ided a bearing 195 on the frame 187 at each end of each roll. The splittirig-rodev 189 are supported in holders 196, a pair of which is mounted on a bracket 197 attached to each side of the frame 197. The bearings 195 and the brackets ll)? rise aboye the frame 187, said brackets being in front of said bearings, and the bearings for the shaft of the roller 188 being: in front of the bearings for the shaft of the roller Mounted on the frame 187. in front of the brackets 19]". a pair of supports 198 for the comb 190, and similarly mounted in front of said supports is a pair of bearings 19!) for a shaft 200 upon which is mounted the roller 191. The roll 192 is mounted below the roll 191 on a shaft 901 which has its bearings in the frame 197, and the roll 193 is mounted on a shaft 202 which also has its bearings in said fran'ie. The roll 193 is at the front end of the frame 1%; and is in contact with the roll 1952. as also is the roll 191. The warp-beam 186 is in front of the roll 192 and below the roll 193. The warp-beam 186 is supported at one end by a short shaft or spindle 20:7 jonrnaled in a forward!v-extqnding bearing bracket 20% at the front end of th frame 19? on one side. and said warp beam is supported at the other end on a rod .205 slidingrlv mounted in a bracket 207 on the other s. e of said framc see Fig. 2. The spindle 363 has a clutch. coupling or friction member 306 to engage the contiguous end of the warpd'ieam 186 and cause said beam to rotate with said spindle. The warp-baim has truiini(riis,eiie of which appears at 20% in Fig. 2, and these trunnions are received in recesses in adjacent end of the spindle 203 and rod 1505. respectively. A handscrew 20%) is tapped into the bracket .36? to engage the rod 205 and prevent it from slipping out of engagement with the trunnion 208 at that end of the warp-beam 166. To release the warp-beam 186 for reino al, it is simply OQCQSSZH') to loosen the band-screw 2G9. slide the rod 205 out of engagcment with and away from the trunnion 26S. sup 'iorted thereby, and take said beam away from the spindle 203 and the member 7206. This or another arpbeam is as readily mounted in the machine.

A shaft 214 is journaled in the frame 18'? below the shaft 201, and carries at one terminal a sprocket-wheel 211 and at the other terminal a pinion 212. A sprocket-chain 213 drives the sprocket-wheel 211, the shaft 210 and the pinion 211 from a sprocket wheel, on the foremost countershaft 8, similar to the sprocket-wheel that is shown thereon at 7. There is a gear 214 which is secured on the shaft 201 and is in mesh with the pinion 212. Secured on the spindle 203 is a gear 216 that meshes with the gear 214. Thus the roll 192 and the friction device for the warp-beam 186 are driven positively, while the rolls 191 and 193 are actuated by reason of their contact with said roll 192, or by the warp 10 in traveling over said rolls 191 and 193. The measuring-rolls 185 and 188 are also actuated by the moving warp. The warp-beam is not driven positively by the friction member 206.

The warp 10 passes, in a forwardly direction, under the roll 185, over the roll 188, above and below the rods 189, that is to say, the warp-units pass above and below said rods, through the comb 190, over the roll 191, partly around the roll 192, and over the roll 193 to the warp-beam 186, upon which latter the now finished warp is finally wound. From this point the warp on the warp-beam 186 is taken to a frame wherein said beam is mounted and said warp is drawn into the harnesses and reed for weaving. The roll 185 measures and records the number of yards of the printed warp which pass in contact therewith, and the roll measures and marks the lengths of the cuts or pieces, all in the usual and well-known manner.

The splitting -rods 189 separate the warpunits, which up to this time have been stuck together in a more or less continuous or un broken strip or web, so as to prepare them for the subsequent weaving operation for which they are intended. It is here that the weavers lease is taken and transferred to place between the expansion comb 190 and the draft roll 191. These operations and their purpose are too well known to re quire an explanation of the same in this specification.

A crank 217 is provided for expanding and contracting the comb 190. The purpose of the comb is to fit as it were the warpunits to the loom-beam or, in other words, to properly distribute said warpunits on said beam and compensate for any difference that may exist between the combined width of said units behind said comb and the width or length of said beam. The object of the draft rolls is obvious, and it need only be observed at this place that said rolls are driven in exact time with the rest of the machine, so as to prevent any undue strain from being put upon the printed warpunits.

The operation of this machine as a whole will be well understood from what has gone before, so that but a brief recapitulation of such operation seems to be all that is further required. lVith the asumption that the machine is in order and that the Warp-units have been run into place and have their front ends attached to the warp-beam 186, the operation in question is as follows: The warp-units first leave the section-beams 101 and pass through the leasing-reed 107, and through the adjusting-reed 108 when present, over the guide-rolls 132 and 135 to the size roll 126, and thence between the squeeze- rolls 127 and 128. The warp 10 is now gummed with a special size and it next passes to the cylinder 31 which partially dries the gummed warp. Attention is here called to the fact that the adjusting reed 108, which can be moved for adjustment longitudinally and diagonally, is present only when one or more ribbons or stripes are to be printed on the warp. The gummed or sized and partially dried warp next passes to the backing-cloth or gray 75 and with said gray between the engraved or printing roll 112 and the cylinder 75. The warp is here printed, and is prevented from soiling the cylinder 71 and other supporting members in its course, with the coloring paste with which the printing is done, by the gray 75. After passing through the printing mechanism, both the warp 10 and the gray 75 come in contact with the cylinder 28 before they separate, and said gray, which comes into direct contact with said cylinder, is completely dried, while said warp, which is separated by said gray from said cylinder, is partly dried. From the guideroller 32, the gray passes on its way to the winding-roller 81 where it is rolled up by the winding mechanism provided therefor, and the warp passes upward to clear the cylinder 28 and then forward to the cylinder 167. In passing, as it now does, partly around each of the cylinders 167 and 173, the drying of the warp 10, which was commenced by the cylinder 28, is completed. The warp is now ready for the steam-box 14 and enters the same for the purpose of having the color permanently fixed therein. Upon leaving the steam-box 14, the warp 10 is led partly around the cylinder 21, for the final drying. The warp, having been printed, treated to set the color, and thoroughly dried, is ready, after passing the measuringrolls 185 and 188, to be separated again into units, and to be prepared and put in condition for the loom by having the weaverslease taken therein and being wound on the warp-beam 186. These operations are brought about, at the end of the general operation or the operation as a whole of the machine, with the aid of the rods 189, the reed 190, and the rollers 191, 192 and 193. Vhen the warp-beam 186 is full, it is removed in the manner hereinbefore explained, and an empty beam put in its place.

With this machine the printed Warp is produced expeditiously, perfectly, and economically, in one continuous operation; and the moving parts being driven and timed as they are, there need be practically no stops on account of broken Warp.

The term size, as used herein, is intended to include any adhesive material which is suitable for the purpose of causing the Warp-units to adhere to each other and then being capable of taking the color with which the printing is done.

A great advantage is found in the use of the half-drying cylinder, by reason of the fact that such use dries the warp on one side While leaving it moist on the other, and so prepares it both to take the color to the best advantage and to insure the thorough and complete penetration of the color, the latter first being received on the dry side and then passing through to the damp side. Homogeneous results are obtained in this Way and by this means, that is to say, the coloring is the same throughout the Warp and on both surfaces thereof.

It is immaterial whether the rolls or rollers, in most if not in all cases, have trunnions or are mounted on shafts, consequently no particular attention need be paid to the use of these terms.

It should be stated more clearly, perhaps, than has been done hereinbefore, that the adhesive material and the half-drying cylinder prepare the warp for printing by first sticking the Warp-units together and then drying one sidctl1e side that is to receive the color. It would be impracticable to attempt to print on loose warp, or on warp that Was either dry throughout or moist throughout, as will readily be understood.
