To ALL WHOM ITMAY coNenRN:

Be it'known that 1I, JOHN H. WILLIAMS, of Essen, county o f Middlesex, and State of Connecticut, have invented anew anduseful Improvenientin the Method of Covering or Painting Floor-Cloth; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accom-Y panying drawings, and to the letters of reference marked thereon; said drawings constitute part of this speciiieation,A and represent, in-`,

Figure 1, the side view of my improvement.

Figure 2, a plan view of the same. i.

Figure 3 is a eross-section, showing the spring-plates open for the reception of the cloth.

Figure 4 is a cross-section, showing the'spring-plates drawn together and cloth inserted.l

Similar letters of reference, when they occur in the dilferent views, indicate like parts.

My invention relates tol an improvement in the method or manner of mechanically lling, covering, or painting Hoor-cloth, and consists of a machine in which the cloth', after -being passed through tho paint, is carried between 01' under one ormore sets of spring-plates, or their equivalents, which press the paint into the cloth, and also give it a peculiarly smooth surface; whereas, inthe method now used for thus preparing floor-cloth,

a great amount of time and-labor has to be expended uponthe cloth after it is lled or painted, to obtain the proper smoothness of surface to allow of its being printed and nished.

To enable others skilled in the art to 'make and use my invention, I will proceed to describe the construction and operation ofthe same. I y

A is a vat or trough, in which the paint, after heingl properly prepared, is contained. Held in movable bearings, and slidingvertieally in the same trough A, a roll, B, is'placed, the `object of which isto immerse the cloth in the paint.-

C C are two spring-plates, or their equivalents, constructed of steel, or other suitable material, arranged to swing, or otherwise, as convenient, and adjustedor drawn together by means of thumb-screws, a,ror other con- 4venient devices, betweenwhich lsaid plates the cloth passes` after leaving the vat or trough A, the object of these plates being to regulate the amount or quantity of paint upon the cloth, and distribute 4the same evenly over the surface, notwithstanding the unevenness of said cloth.

D D are two spring-plates, or their equivalents. The lower'of said plates is held stationary, or otherwise convenient; the upper one swings on hearingfs, and is operated or pressed down upon the under plate by means of lever Z), or other convenient device. Between these'two plates the cloth-is passed in 'order to smooth and polish the same.- n

Thisgeempletesthe construction of my'improvement. The operation is as follows:

First, the requisite amount of properly-prepared4 paint is placed in the vat or trough A; the cloth is then introduced and passed under theroll B, to allow-of which, the said roll is raised'ahove the surface ofthe paint, as shown in'lig. 3. .The said roll is then lowered to a sufiicien't depth in the vat or trough to thoroughly immerse the'cloth in the paint. fter this the cloth is drawn, first between thetwo spring-plates C C, said plates being brought together by means of the thumblscrews a, and pressed against the cloth, which give them the curve, as shown in fig. 4. This curve in these plates gives the cloth, as it passes, apeeuliar drawing-pressure, andinstead of simply-scraping the paint 'from thesurfaCe, ldistributes it evenly over it,`without regard tothe unevenness of the cloth, After the cloth has passed between the two said plates, C C, it is drawn forward over the roll and between the other set of plates D D. These said plates are similar to the said plates C C, exceptjhat they Aare made longer, for the reason that they're intended for smoothing and finishing the surface instead of removing the superfluous quantity of 'paint therefrom. These plates may be pressed together and against the cloth by means of lever b, o r other convenient dev iec, as shown in iig. 4.

A great advantage of 'these spring-plates is, that when any unevenness, wherever it may occur in the cloth that passes between them, thepsaid spring-.plates adjust themselves to it in that particular place, while all around it the surface will be as smooth as if it had been perfectly even whereas, ina smoother which is held without a spring, the unevenness is either torn away orelse lthe smoother, in being raised to clear it, make a ridge or.

uneven place the whole width .of the cloth, which has to be smoothed before the cloth can be painted.

The peculiar advantage, however, is the curving of the plates, by which the cloth,'as it passes, is given a drawing or ysmoothing motion, similar-to that given-to plaster by a trowel. V

I amaware that'thi's curvature .may be given to a rigid lsurface of `metal or wood, and may be used to advantage in the place of the springs herein described, but as this curvature renders their action similar,` as far as the drawing-pressure is concerned, to'the springplates, I have not considered it necessary to describe any-other particular method of construction.

Ido not conne myself exclusively tothe'luse: of springs, or any number' of springs, between which the y cloth passes, for if one sido of said cloth is to be nished,'only one plate will be required. This plate will be vconstructed and operated in the same manner as those described, the cloth resting. the opposite side upon a roller or plain' surface. v

4Having thus fully describediny invention, what I claim asfncw and useful, and desireV to secure by Letters Patent, is y '1. The spring-plates C O, or their equivalents, for distributing the paint evenly over the surface of the cloth', and also removel the extra amount of the same, substantially in the manner andfor the purposespecied.

2. The spring-platesl) D`,'or their equivalents, as a smoothing-device, for the purpose of inishing the cloth', `substantially as herein described. x s,

3. '.lhje peculiar" curve of the plates herein described, when incperaticm,l constructed of springs, or their equivalents, to give the smooth and polished surface to the' cloth as it passes'through the machine, in the manner described and for the'purpiose speciiied.
