IMPROVEMENT IN FIN-ISHING CLOTH.

Specification forming part of Letters Patent N 0. 174,308, dated February 29, 1876; application filed i November 19, 1875.

To all whom t may concern:A n

Be it known that I, CHARLES E. SGRIM- GEOUR, of Almonte, in thecounty of Lanark, in the'Province of Ontario and Dominion of Canada, have invented a new and'useful Improvement on Process for Finishing Oloth, of which the following is a specification: f

This invention has for its object to improve and facilitate the finishing of cloth in the process of steaming its face; `and it consists in means for subjecting the face of the cloth to the action of vapor generated from water, to remove the gloss on itsface, and creases resulting from the ordinary pressing process.

The-apparatus for carrying out and eecting such process consists of the combinationof a water-tank having induction steam-pipe and outlet vapor-pipe connected with a perforated cylinder and boxing orother distributing device for applying the vapor to the surface of the cloth.

Figure l in the drawing represents a sectional view of my apparatus. Fig. 2 is a top view of a portion of the same.

Similar letters of yreference indicate corresponding parts.

A is a close tank to be partly lled with water; B is the steam-induction pipe connecting with the engineboiler and entering the tank A from above to below the waterline. C is the eduction Vapor-pipe leading from the tank A above the water-line to a perforated cylinder, D, in a box, E, open at the top, or other suitable device for distributing the vapor, which will be generated from the water in the tank on the induction of steam from the boiler through the pipe B. F is the cloth, which, after being subjected to the usual pressing process, is passed over the vapor-box E in the usual manner.

J 4is an automatic-acting piston for the purpose of shutting off steam from the boiler through the valve x in the induction-pipe B when an excess of vapor is generated.A

In the manufacture of cloth the ordinary pressing process produces, on both sides of the cloth, a smooth glossy surface, and in the process of passing the cloth with the face downward 'over the vapor-box E the gloss is removed from that' side of the cloth, leaving the reverse side in the glossystate, and retaining all `the firmness produced by the .pressing process while the goods are free from the heat occasioned by the use of direct steam. The removal of thisiglossfrom the face of the cloth is quickly and efficiently effected by the passing of the cloth once or twice over the moist vapor generated inthe tank A by the injection of steam from an ordinary engine-boiler. The usual way is to take steam from the boilers of the mill and apply it through the perforated cylinder. The object is to take oft' the glazed appear'- ance the goods have after pressing, and to remove the fold-marks4 occasioned by the press-papers in the process of pressing.

It is important that as much as possible of the rmness acquired by the hard pressing be retained while giving the face of the cloth a soft yet smooth feel to the hand.

In the usual way of applying the steam the cloth requires to pass several times over the steam in order to get the uniform appearance necessary, and the difficulty experienced in almost every mill is to keep the goods cool, retain the firmness, and yet have the glazed surface uniformly removed.

I find, in practice, that all this, by this imi provement, can be done by one or, at most, two revolutions.

The process is simply rst passing the steam through water before applying it through the cylinder previously mentioned. In other words, the steam is passedinto an inclosed vessel partly lled with water. The water boils and gives off steam, which is used for the purpose mentioned in place of direct steam from boiler. The steam is moistin place of dry.

Ordinarily the steam is brought as directly as possible from the boiler to the cloth, being thus at a maximum of pressure and dryness.

The result of this is that it requires repeated applications to effect the desired object, and these tend to lessen the firmness that has been produced by pressure and the gloss that is on the back, which-is very undesirable. These objections are removed by the use of wet steam, the result being attained at a lower temperature, at a less pressure, and in a very brief time.
