A (DBPORATION' OF NEW YORK APPARATUS TREATING FABRICS Application filed November 80, 1985. Serial No. 70,415.

This invention relates to apparatus for treating fabrics.

An object of the invention is to provide efficient and durable apparatus for treating the fabrics.

Processes for the treatment of fabrics with certain chemicals or reagents at certain desiredtemperatures are known. In such processes it is important to keep the temperature of the reagent acting upon the fabric within certain narrow temperature limits.

This invention is of particular value in connection with such processes, as one of will insure that all portions of the reagent while acting upon the goods are maintained at substantially the same temperature.

I have found that greatly improved results may be obtained by not only maintaining the temperature of the body of the reagent constant, but also by keeping the fabricbelow the liquid level of the reagent throughout substantially the entire period during which the reagent is acting upon the fabric, as this insures a more uniform temperature of all portions :of the reagents acting on the fabric substantially throughout the period in which it is acting.

Further objects of the invention will more fully appear from the following description taken in connection with the accompanying drawings illustrating, by way of example,

the preferred embodiment of the apparatus used in carrying out the process.

The invention consists in the novel features, arrangement, construction and combination of parts of the apparatus and means hereinafter described in accordance with certain preferred embodiments thereof, and the invention will be more particularly pointed out in the appended claims.

Referring to the accompanying drawings:

Fig. 1 is a side elevation of the apparatus with certain parts broken away, and i Fig. 2 is a plan view of theapparatus with certain parts broken away. I Y 1 Apparatus its" objects is the provision of apparatus which vwhich are used. In the present embodiment,

this lining 4 is constructed of wood, to withstand caustic alkali, and as shown in Fig. 1

is formedof groove and tongue boards. The top of the tank is provided with sections, such for example as 5 (Fig. 2), which are hinged to rigid portions of the top such as 6 and these sections are provided with suit-- able handles 7 by which they may be opened in order to inspect parts of the ap aratus within the tank. The entire top of t e tank is constructed in a manner similar to that employed in the construction of the sides, bottom and ends of the tank,-i. e. an outer layer of metal and inner lining of wood and a layer of asbestos between the inner and outer lining. The tank so formed is watertight, is thermally insulated, and is adapted to be filled with chemicals or reagents in solution form which in the present embodiment is a caustic alkali, such for example as caustic soda, for treating the fabric.

Suitable power driven rolls such as the

cylindrical rolls

8, 9, 10,11, 12, 13, 14, 15, 16, 17, 18 and 19, preferably provided with rubber surfaces, are mounted within the tank adjacent the bottom thereof and are supported in suitable bearings. One end of the axle of each of these rolls, with the exception drive engaging portion or each of said rolls. "Each of these bevelled gears 20 is in mesh with a cooperating driving pinion 21. Driving pinions 21 are fastened to driving shaft 22 extending longitudinally of the tank and supported on suitable bearings 23. A bevel 'gear' 24 is attached to this shaft 22 adjacent t-he right hand end thereof and is in mesh-with a driving bevelled gear 25 attached to the shaft 26, which is supported in suitable bearings and which'is provided with a driving pulley 27, by means of which suitable motive means may be applied through the intermediary of a pulley belt to thereby rotate the power driven rolls. The roll 18 is driven from roll 16 in the following manner: a sprocket 28 is attached to the roll 16 and carries a driving chain 29 which engages a sprocket 30 carried by the roll 18. The roll 19 is driven in a similar manner by means of a sprocket 31 carried at the end of the roll 17 adjacent to the front of the apparatus and engaging a chain 32 which also engages a sprocket 33 carried by the roll 19 at the end adjacent the front of the machine. It will therefore be seen that when the machine is in operation, the rolls 8 to 19 inclusive are rotated by suitable motive means applied to the pulley 27. The direction of rotation of each of the rolls of this series is the same, and is in an anticlockwise direction with reference to Fig. 1.

A series of

friction rolls

34, 35, 36, 37, 3 8, 39, 40, 41, 42, 43 and 44 are supported by the power driven rolls; each of the friction rolls being supported by two of the power rolls. The friction rolls are preferably cylindrical in form and are in the form of metal pipes open at the ends and of comparatively thick walls. Both the power driven rolls and the friction rolls are positioned in the tank at a point below the liquid level of the tank. By this I mean that the treating solutlon in the tank is maintained at such a level that the power driven rolls and the friction rolls will be substantially submerged.

An idle roll 45 is mounted adjacent the left hand end of the tank on an extension of the frame 1. A plurality of Mycock rolls designated as 46 are mounted on an extension of the frame 1 adjacent the idle roll 45 between the idle roll 45 and the'tank. A roll 47 is mounted within the tank adjacent the top of the power driven roll 8.

A similar roll 48 is mounted within the tank at the right hand end thereof adjacent the power driven roll 19.

A foulard of the type well known to those skilled in the art is mounted adjacent the right hand end of the tank and carries the usual rolls 49 and 50. The foulard is operated by suitable motive means applied to .the pulley 51 2).

An open top tank 52 is provided adjacent the right hand side of the foulard machine and

idle rolls

53, 54, 55 and 56 are supported by this tank in suitable bearings.

Suitable means is provided for maintainsystem such as is wellknown to those skilled n the art.

l Operation The insulated tank is filled with the liquid reagent desired, for example according to one use of the invention a caustic alkali of a strength of at least 15 Baum, to a level which will substantially cover the top of the friction rolls. The refrigerating apparatus s now put into operation to bring the treating solution, i. e. the caustic alkali, to and maintain it at the desired temperature; which temperature is substantially maintained throu bout the treatment. For example, if the fa ric is to be treated to produce a linen like effect according to Patent No. 1,439,519, the caustic alkali may be of a strength of 30 Baum and maintained at a temperature of about minus 10 C. a

For such treatment the fabric to be treated is started through the machine by means of a web in the manner well understood by those skilled in the art. The fabric passes below and around the roll 45 and'through the cock rolls 46, which stretch the fabric transversely, thence around the roll 47 around and beneath the roll 8, up over the friction roll 34, down and beneath the roll 9, and so on alternately between one of the power driven rolls and one of the friction rolls, around one of the friction rolls and so on until the fabric has passed around each respective roll of both series of rolls. In this way the fabric is not only firmly held against the power driven rolls and the friction rolls, but also acts to drive the friction rolls as the fabric is moved through the machine by the power driven rolls. The speed of the fabric in such treatment is timed so that it is immersed in caustic alkali for say one to two minutes. The fabric is then passed over the roll 48 and thence out of the treating tank and up between the rolls 49 and 50 of the foulard. From this point the fabric may be passed down into the tank 52 which may contain a washing solution such as water. The fabric passes beneath roll 53, over roll 54, beneaththe roll 55, over the roll 56, and thence out of the machine.

It will therefore be seen that the .fabric is first stretched transversely or laterally, thence it is passed into the treating solution which is maintained at substantially a con. stant, relatively low temperature and the fabric is held in a transversely stretched condition and it is passed at a uniform predetermined rate of speed through the treating solution or reagent beneath the liquid evel thereof during substantially the entire period that it is sub ected to the caustic alkali or other reagent and is then assed out through the foulard. From the oulard the fabric may be passed through the tank 52 where it may be additionally treated or washed according to the finish desired- According to this method and apparatus,

all parts of the fabric which are being acted u on by the reagent are immersed in the body of the reagent so as to insure all portions of the reagent that are acting upon the fabric being maintained at the desired temperature 20. ofthe body of the reagent, the temperature of which is controlled. 7

While I have described my invention in connection with the use of a caustic alkali, such for example as caustic soda, at a partic-' ular low temperature, it is to be understood that the invention is useful in any case where it is desired to have any reagent act upon the fabric within some particular narrow range of temperature limits, and particularly where this range is substantially above or below room temperature.

Having thus described my invention 1n detail in its present preferredembodiment, it will be obvious to those skilled in the art, after understanding my invention, that various chan es and modifications may be made therein WlfilOllt departing from the spirit and scope thereof, and I aim in the appended claims to cover all such modifications and changes.
