WAXING PAPER.

SPECIFICATION forming part of Letters Patent No. 365,213, dated June 21, 1887.

Application filed November 20, 1985,

(No model.)

To wZZ whom it may concern:

Be it known that 1, CHARLES A. WILKIN- soN, of East Somerville, in the county of Middlesex and State of Massachusetts, have invented a new and Improved Process of \Vaxing Paper, of which the following is a full, clear, and exact description.

My invention relates to the manufacture of what is known tothe trade as waxed pa- IO per, and the invention consists of an apparatus for carrying such method or process into effect, as will be hereinafter explained, and specifically pointed out in the claims.

Reference is to be had to the accompanying r drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a perspective view of the apparatus employed to carry out my improved process of waxing paper. Fig. 2 is a longitudinal sectional elevation of the same. Fig. 3 is a cross-sectional elevation of the apparatus.

In carrying my improved method of waxing paper into operation, I employ such an apparatus as is illustrated in the drawings above referred to, wherein there is shown a metallic box, A, preferably formed of castiron, and having a sunken upper surface which is slightly corrugated, the corrugations run ning across the face of the sunken portion, as

shown at a a. 7

Along each side of the depressed or sunken surface there is a deep gutter, I), and leading into one of these gutters is a funnel, B, by

.means of which melted wax or paraffine is poured into the gutter, so as to flow across the corrugated surfaceof the box.

A sheet of perforated boiler-iron, c, is placed upon the corrugated surface of the depressed 4o portion of the box A, the perforationsin said sheet being very fine and very close together, while a number of sheets of felt, (I d, are placed upon the plate 0, a sufficient number of such sheets of felt being employed to bring the up- 5 per surface of the pile just above the edges 66 of the box A.

A groove, 0, is formed near one end of the upper surface of the box, and this groove is lined with felt g, which. is cemented to the box,

the idea being to provide a place where a roller, 1), may be placed when not in. use, and the felt lining being provided in order that the roller, which should have a perfectly-smooth surface, may not be dented by coming in con tact with the sharp edges of the iron.

A supply-pipe, E, and an exhaust-pipe, F, are iittedin one end of the box A, so that steam may be supplied to the interior of the box, which has to be heated in the operation of waxing paper.

The operation is as follows: The machine having been set up and properly leveled, melted wax or paraffine is poured into the fun nel B, a sufficient amount being introduced to thoroughly saturate the felt above the plate 0. The steam is then turned on and the temperature'raised to about 230 Fahrenheit. The paper may now be waxed by placing the sheets upon the felt-bed and passing the roller 1 over their upper surfaces, the sheets being placed singly and successively upon the bed, and lifted therefrom and piled, after being subjected to the pressure of the roller, the ac tion of the air while the sheet is being trans 'ferred from the waxing-machine to the pile being sufficient to cool and set the wax and prevent the sheets fromsticking together when piled.

This method and apparatus for waxing paper is more especially adapted for use in the waxing of tissue-paper, but may be employed with advantage in the waxing of any of the lighter grades of paper.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In an apparatus for waxing paper, the combination,with a box provided with steampipes and having an upper depressed and eorrugated surface, of a perforated plate, 0, and felt sheets (i d, substantially as described.

2. In an apparatus for' waxing paper, the combination, with a box provided with steampipes,and having an upper depressed and eorrugated surface, and gutters b I), .fcd by a funnel, B, of a perforated plate, 0, felt sheets (I (I, and a roller, D, substantially as described.

CHARLES A. WILKINSON.
