THOMAS MESSENGER DROWN, OE PHILADELPHIA, PENNSYLVANIA, AS

SIGNOR TO W. A.DROWN,.OE SAME PLAGE.

Letters Patent No. 110,907, dated January 10, 1871.

The Schedule referred to in these Letters Patent and making parl: of the same.

I, THOMAS MESSENGER Dnows, of Philadelphia, county of Ihiladelphia, State of Pennsylvania, have invented an Apparatus for Dyeing or Impregnating Fabrics, of which thc' following is a speciiication.

Nature (tml Object of the Invention..

My invention consists ofap1'ia1'atus,too fully dcscribed hereafter to need preliminary explanation, for dyeing or water-proofing fabrics, thc main object of my invention being the impregnation of theV fabrics without exposing much of the liquid to air and light,`

thereby preventing the rapid evaporation or deterioration of the liquid,and when the latter is of an inflammable character of preventing accidents from ignition.

Description of thc Accompanying Drawing/5 Figure 1 isI a sectional perspective view of my `in1- proved apparatus for dyeing or impregnating fabrics; and Y Figure 2, a planvicw of the same.

General Description.

A represents a rectangular box provided with a hinged lid, a, and containing au angular reservoir, B.

The fabric to be treated is passed through a.slit, b, in the'top of the box, umleraroller, c, arranged near the bottom of the reservoir, then between pressing and drawing-rollers, h h, above the reservoir, and linally through a slit, b, in the front of the box.

rIhe drawingr and pressing-rollers h li. are geared together at one or both ends so that they maybe operated simultaneously, and are contained within the box' above a shelf or partition, t', which maybe slight-ly inclined or otherwise arranged in such a manner as to conduct back into the reservoir the superfluous liquid expressed from the fabric in passing between the rollers.

lhe reservoir is supplied with a sufficient quantity of the liquid, with which the fabric is to be treated, to cover the roller c, by a pipe, j, which enters the reservoir beneath the said roller and'communicates with the lower part of a closed tank, C, arranged at such a height above the said reservoir as to enable the liquid to iiow into the. same by its own gravity.

A pipe., K, also extends from ythe top of the said tank into the reservoir, and terminates within the latter at a point coinciding with the desired height of the liquid.

This pipe is designed to supply air to the tank as therliquid tlows from the latter through the pipej into thereservoir.

When the liquid rises in thereservoir to a point above the open end ofthe said pipe It, the ow through the pipe j must cease until the level of the liquid again descends so as to enable air to enter the tank. Thus a constant and uniform self-regulating supply of liquid, at any determined level, can be maintained in the reservoir.

lBoth of `the pipes j and It are furnished with stopcocks, m, so as to enable the supply of iiqnid to the reservoir and of air to the tank to be cut off at any time; and the said pipes, which can be flexible if desired, may be of any length, according to the position of tbe tank in respect to the reservoir, which may be placed''at a considerable distance from the tank to avoid accidents where the liquids employed are tia light inflammable nature.

-The above apparatus has been designed especially for dyeing fabrics with materiulswhich would be injured by'exposnre to the air or light, and also for impregnating fabrics with substances held in solution in'volatile liquids, such, for instance, as spermaceti dissolved in benzine or naphtha for waterlprooting purposes.

,Ihe advantages of the apparatus for such purposes may be briefly described as follows:

The closed box or vessel prevents deteriorationof the liquids employed by direct exposure to air or light,A

and also'prevents the escape of the vapors of volatile liquids.

The arrangement of the pipes in respect to the'tank 'and reservoir prevents unnecessary exposure or loss of liquid by'maintaiuing a suiicient but comparatively small quantity of the latter in the reservoir.

. The arrangement of pipes, and the fact that the tank, with which they are connected, can be at'any cle-,-

sired distance from the reservoir, also permit-s benzine and similar inflammable substapces to be used with perfect safety.

lhe arrangement 'of the drawing and pressingrollers within the box and above thcreservoir also 'prevents unnecessary loss of liquid, as all of the matter which is expressed from the fabric in passing between the said rollers can dow back into the reservoir.

Claims.

l. A reservoir, containing volatile impregnating material, closed to prevent the evaporation of the said material,-`bnt slit at two points to permit the passage through it of a strip of fabric to be impregnated, as set forth.

2. The combination of said reservoir and a tank, c, communicating with the reservoir, as described In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.'4 l
