To all whom t may concern: y

Be it known that I, JOHN ZIMMERMANN,

of Philadelphia, in the county of Philadel? phia and State of Pennsylvania,` have invented certain new and useful Improvements in VVarp-Printing Machines, whereof the following is a specification, reference being had to the accompanying drawings.

The invention relates to new and useful improvements in warp printing machines wherein thevcoloring matter is applied to the warp threads byv pattern-controlled mechanism.

An object of the invention is to provide a machine of the above character with devices whereby the warp threads as they pass continuously through the machine, may be supplied uniformly with coloring matter in aecordance with a predetermined pattern.

A' further object of the invention is to provide a printing device for a warp thread machine of the above character wherein the printing Vrolls are partly submerged in the coloring matter and wherein a device is provided for evenly distributing the coloring matter on the surface of each printing rol said device being so constructed as to maintain a uniform surface of coloring matter regardless of any inequality in the surface of the said printing rolls.

A further object of the invention is to provide a printing device of the above character, wherein the warp threads arecontinuously passed through the printing device, and the different colors applied simultaneously, with means for setting the printing color in the warp threads, plogether with dcvices for washing'the siz'ng and surplus color from the threads, and subsequently drying the same. f u

These and other' objects will in part beobvious, and will in part be hereinafter more fully disclosed. 4 ln the drawings, which show by way of illustration one embodiment of the invention: Figure I is a side elevation of an apparatus having my improvements applied thereto; Fig. H is an'enlarged side view of a portion of the printing device; Fig. lill isa detail showing in section one of the printing rolls and the means for causing the thread to engage the same; Fig. lV is a view in section showing one end of the drying chamber and the means for washing the' thread; and lFig. V is a bottom plan View of one of the color distributing devices.

.The invention consists generally in providing a supporting frame on which the beam containing the warp threads to be colored are mounted. The warp threads are led from this beam through a printing devvice wherein printing rolls, partly submerged in coloring matter, are caused by a pattern controlled mechanism to be engaged by the threads, thus producing in colors on the threads, predetermined patterns, after which `said threads are passed through a steaming chamber where the colors are set and from the steaming chamber the threads are led through a washing apparatus which removes the sizing and surplus dye from the threads. After leaving the washing apparatus, the surface water clinging to the threads is stripped therefrom pneumatically, after which the threads are led through a drying chamber. -The-threads arepassed continuously through these several devices and are finally wound on suitable beams.

The printing devices for the threads consist of a'series of printing rolls each of which runs in a color box so that the rolls are partly submerged in the coloring matter. A distributing device coperates with each printing roll to maintain a uniform coating or layer of the coloring matter on a roll at the region where the threads are brought into contact with the rolls.

rlhe washing apparatus consists of a plurality of trays over' which the threads are led and intermittently operated arms which immerse the threads in the water contained in the trays as they move along over the same. The surface water clinging to the threads is stripped therefrom by jets of air located in the path of travel between the washing apparatus and the drying chamber.

Referring more in detail to the drawings, the improved apparatus consists of a sup. porting frame 1, on which is mounted a shaft 2 carrying the supporting beam 3 for the threads to be printed, which threads are indicated at t. This supporting frame l is connected to the frame 4i of the printing device.

IThe warp threads pass over suitable tension rolls 5 and 6 mounted in the frame 4 of the printing apparatus and then around a feed roll rThis feed roll is intermittently operated by a pawl and ratchet mechanism 8. The pawl is carried by a swinging rock arm 9 which may be operated in any suitable way. It is understood that the warp threads pass side by side over the feed roll 7 As herein shown, the printing apparatus includes a series of color boxes 10 which are mounted on a carriage 11 having supporting wheels 12 adapted torun on tracks 13. These tracks are so disposed that the carriage may be run underneath the supporting frame 4 of the printing apparatus and the printing rolls properly positioned beneath the Warp threads. Each color box 10 is provided with a color roll 14 which is mounted in suitable bearings in the box. This printing roll is preferably formed with a continuous printing pad covering 15 which may be of any desired character. The roll -is mounted so that it runs partly submerged in the coloring matter which is indicated at 16 in Fig. III of the drawings.` Each o f these color boxes may be supplied with a diEerent coloring matter and each printing roll extends the full Width of the printing frame so as to be located directly underneath all of the warp threads passing through the printing apparatus.

The supporting rolls for the warp threads at the leading-in side'of the printing apparatus and the guide roll 17 at the other sideof the apparatus, are so positioned relative to the carriage supporting the coloring boxes and the printing rolls that the normal path of travel of the threads through the printing apparatus is slightly above the surface of the printing rolls, as clearly shown in Figs. II and III.

Coperating with each printing roll is a series of impression members 18. There is an impression member for each line of warp threads "passing over the printing rolls and there is an impression member located above eachthread for each printing roll. As shown in Fig. II of the drawing there are eight series of impression members and coperating with these eight series of impression members are eight printing rolls, each of which runs in a separate color box as above noted. These impression members, as shown in the drawings are arranged-so as to be moved vertically by supporting cords 19 actuated by a -suitable jacquard pattern mechanism. This pattern mechanism operates to lower the impression members in accordance with the pattern desired. When the impression member is lowered it drops upon the warp thread and forces the same down into contact with the surface of the printing roll directly underneath the lowered impression member. When an impression member is lowered so as to bring the warp thread into contact with the printing roll, said thread will be coated or printed with the coloring matter of the roll with `end of the printing roll and are pivotally supported by brackets 21 attached to the color box. These eveners on their under faces are formed with projecting ribs 22 and said evener sections bear. by. gravity upon the surface of the printing roll.l The height of these ribs determines the thickness of the layer of coloring matter permitted to remain on the surface of the printing roll. As the roll rotates in the direction of the arrowin Fig. III, the lower edge of the 'evener will scrape off all the coloring matter, except that which passes underneath the same and is thus distributed in a uniform layer of.I coloring matter throughout the entire length of the printing roll. If there should be slightly uneven places in the surface of the roll, inasmuch as the evener coniprises several sections andv extends from end to end thereof and has a straight edge underface, the surface' of the coating material left on the coating roll will be smooth and without irregularities.y By the above construction of the distributing device, the printing rolls may be caused to rotate directly in the coloring matter and an even coating of coloring matter supplied to the warp threads. It will be understood that each -printing roll is provided with a sepalrate distributing device. The printing rolls are intermittently rotated by suitable intermeshing gears mounted on the ends of the rollers and these gears may be driven from the feeding roll 7, through an intermediate gear 23. It will be understood of course, that adjacent printing rolls are rotated in opposite directlons as each printing roll is geared to its adjacent fellow.

The distributing devices are positioned relative to the direction of rotation of the printing rolls so as to engage the coloring matter on the printing rolls before the printing rolls come into contact with the warp threads. y

After leaving the printing apparatus, it is desired to pass the warp threads with the coloring matter thereon to a steaming chamber so that the coloring matter may be set in the threads. In Fig. I of the drawings, I have shown a steaming chamber 24. The warp threads after passing over'the guiding roller 17 are led over a guiding roller 25 carried by a bracket attached to the outer wall of the steaming Ichamber and are then led into the steaming chamber, the threads running back and forth horizontally over the guiding rolls/26 at the opposite ends of the steaming chamber. Said steaming chamber is supplied with steam through the `piping 27.

The threads after leaving the steaming chamber pass over a guiding roller 28' and thence through a washing apparatus. This washing apparatus consists of a series of pans 29 and the threads pass over these pans and about a guiding roller 30 at the other end of the main frame ofthe apparatus.. These pans are kept supplied with a continuous flow of Water through a pipe 31 which discharges into' each of the pans and the overflow from the pans is received by the trough 32 which extends underneath the ans. p Associated with each pan is a cross shaft 33 carrying oppositely extending

arms

34 and 35. These arms carry paddles 36 which extend `from side to side of the apparatus. The arms are oscilla-ted by means of links 37 which coperate with suitable eccentrics 38 on the driving shaft 39, see Fig. 1V. As the arms are oscillated, rst the paddle carried by the arms 34 will engage the threads and immerse the same in the water in the pans and then the paddle carried by the arms will engage the threads and direct their course beneath the surface of the water so that they are immersed. It will be understood that although the threads are traveling continuously over the pans their course of travel will be constantly changed so that they are immersed beneath the` surface of the water in one region and then another and this greatly facilitates the thorough washing of the threads. Iny employing a series of independent trays in the washing apparatus a more thorough washing may be -obtained since' the dyes and sizing eliminated in one tray cannot be carried into Vthe next. c

After passing through the washing pans, the threads are subjected to a blast of air from pipe 40. The 'jets of air from the pipe on to the threads strip the Water from the surface of the threads. The water stripped from the threads at this point is caught in the trough 32. y

The threads after leaving the guiding roll 30 are carried through a drying chamber 41 and led over rollers lf2-4:2 at the opposite ends of the drying chamber. Pipe coils 43 extend across the drying chamber and serve as a heating means to assist in drying the warp threads. chamber, the threads are led over guiding feed rollers 44, thence over suitable guiding rolls 45 and 46, after which the warp threads are rewound on beams 47.

From the above description it will be apguiding a plurality of war After leaving the drying' parent that the warp threads are passed through aprinting device where they are uniformly printed in accordance with any desired pattern, after which they are passed to a'steaming chamber wherein the coloring matter is set in the threads and thence the threads are led to a washing device for removing the sizing and the surplus coloring matter.- rlhe water clinging to the threads is removed to a large extent by jets of air playing on the same and finally the threads are dried and rewound for use in the looms. It is obvious that the warp thread above referred to may consist of one or more Warp threads.

It is also obvious that minor changes in the details of construction and arrangement of parts may be made without departing lfrom the spirit of the invention as set forth in the appended claims. v
