f OUTDOOR SIGN- Application filed October 29, 1923. Serial.` No. 671,406.

My invention relates to an outdoor sign formedl of iibreboard, as distinguished from metal signs generally. For many years I have been engaged in the manufacture of outdoorl signs for advertising purposes to the extent to make certain that a properly treated iece of fibreboard will outlast, for the desired life ofy a sign, any ordinarymetal eignof a character within range of economy.

The processing of such outdoor signs of ibreboard is, however, a matter of great importance in assuring a long life, maintenance of brilliancy `of coloring and assurance of perfect application of printing inks and colors.

Itis my object' in this invention to provide a process of preparing outdoor signs of libreboard so as to lill and cap all pores with a moisture resistant material, to prepare a satisfactory printing mat or surface upon the board, to print or decorate the board and nally to coact the printed surface together with the board with a varnish-like material, and to protect the edgesof the board.

While I speak in the speciiications that follow of a piece of iibreboard, it should be understood that what I refer' to is a piece of material having tibreboard on the outside, without reference to the number of plies of brous material, or the presence or absence of a stitfener or filler of any other nature.

I am aware that signs have been manufactured of cardboard for many years, in which attempts have been made to render the sign waterproof, but never, so far as I am aware, with complete success, and my present invention represents the refinement in processing devised by me, whereby the lboards have been produced in a way which almost entirely precludes the entrance of moisture into the board, and the consequent disintegration of the paper or scaling oli' of the printed matter, as is frequently the case with other signs.

I accomplish my objects by the certain process to be hereinafter more specifically pointed out and claimed.

In the drawing:

Figure 1 is a perspective view of one of my signs.

Figure 2 is a cross section thereof.

The breboard either after being cut to size or in the large mill size sheets is, if

necessary, put througli a process to remove a percentage of the moisture. It is not so important that any one given percent of moisture should remain in the board, ybut rather that the sheets before treatment shouldbebrought to a. uniform, fairlylow moisture content, so that a regular system of impregnating can be followed without resulting in irregular product. The resultant boardl is now immersed in a bath of either hotor cold compound suitable for impregnating it, the temperature in no case being greater than about 2000 F., since much higher ten'iperatures tend to disintegrate the paper. The im'pregna'ting material may consist ofxoils, fats,` protein solutions, or mixtures thereof-in fact, the prima-ry qualification is that the mass shall be water-insoL uble andy possess the necessary qualities of adhering firmly to the paper libre and a setting power or melting point sufificiently high to prevent its being melted by the heat of the sun. Immersion ofthe board in hot molten waxes such as ceresin, ozokerite, carnauba or sandarac, or mixtures thereof may be suitable for the purpose. In my preferred process, I employ a. solution of casein and the resultant impregnated board is thereafter treated with formaldehyde, said two substances combining with cach other so as to form an almost ideal medium.

After thorough impregnation of the board and practically complete filling of the spaces between the fibers, the board is run between rollers under light pressure` to remove the excess from the surface. The resulting thoroughly impregnated board is now white or color coated with a combination consisting of a. drying varnish and a pigment and may then be dried, and subsequently printed, stenciled or lithographed in as many colors as may seem desirable for working out the design or announcement. The printed board is now varnished with one or more coats of Hong-lived, moisture resisting varnish to render the boa-rd as nearly weatherproof as possible. It is then bound with metal .strips crimped around its edges to stiften it, and also to exclude moisture getting in between the plies, where this is a danger, due to the way the board isbuilt up.

The attached drawing shows the ideas graphically both flat and cross section, corresponding numerals indicating the different parts. lis the board, 2 the first coating,

Cil

so l,

3 the second coating and 4 the varnish coating. The binding 5 is then applied as shown.

The particular point which I Wish to cover is the method of impregnating thoroughly the fibreboard to be used with an inexpensive Water-insoluble filling material, and the use of such filled ibreboard in combination with the other products to form a sign. Such aI combination will have very long life and Will render advertising in such a manner less expensive.

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

1. The process of manufacturing an out door sign. consisting first in filling the interstices of a fiber board sheet.I by capping them with an insolubilized casein, secondly coating the board with an ink receptive medium7 thirdl)7 decoratingr the sign With a suitable announcement, fourthlxT varnishing the board.

2. The process of manufacturing an outdoor sign consisting first in filling the interstices of a fiber board sheet by capping them with an insolubilized colloid, secondly coating the board with an ink receptive medium of a type which will receive a decoration imprinted thereon, thirdly decorating the sign with a suitable announcement printed over the coating ot the second step and fonrthly varnishing the board.

The process of manufacturing an out door sign consisting of treating a fibre board with a `casein solution and formaldehyde as a coagulanl. color coating:v the resulting board with a pigment in a drying oil, printing an announcement thereon, and varnishing the surface 'front and back.

4. The process of manufacturing an outdoor sign which includes the steps of capping;r the pores of a fibre board sheet to prevent penetraiirm ol moisture, varnish, and

inl: b v treatment with a casein solution and WILL C. JAMES.
