UNITED STATES PATENT OFFICE.
ROBERT FULTON AND ALEXANDER DE LAND, OF DETROIT, MICHIGAN.
SHEATHING AND ROOFING FOR RAILWAY-CARS.
SPECIFICATION forming part of Letters Patent No. 267,784, dated November 21, 1882, Application filed July 27, 1882. (No specimens.)
To all whom it may concern: Be it known that we, ROBERT FULTON and ALEXANDER DE LANO, of Detroit, in the county of Wayne and State of Michigan, have invented new and useful Improvements in Sheathing and Roofing for Railway-Oars; and we do hereby declare that the following is a full, clear, and exact description thereof.
The nature of this invention relates to certain new and useful improvements in outside coverings for railway-car bodies, by means of which a cheap fire and weather proof roofing and'sheathing is obtained. The employment of wood pulp is preferred, although rag or any other kind of pulp may be used, such as is employed in the manufacture of an yof the.
paper or board stocks.
Our improved sheathing will be found valuable for the car lining and floor, as well as for the outside, and for the roof the proper camber is given to the sheets before they leave the mill on forms of the proper curve.
The pulp is prepared in the usualway, and in passing from the Fourdrinier or other machine is cut into sheets of the desired size. The sheets are now in a flat form, ready. to be used for the sides, ends, and bottom of the car-body. To give the proper camberto the roofsh eets they are placed upon suitable forms and dried on the forms, so that they are then ready for use.
In order to make this sheathing fire and weather proof, the pulp is treated with the following materials before it is sent to the machine: four (4) parts of alum and one (1) part of white soap are dissolved in about eight (8) parts of water, then one-quarter part of glue and one-half part of gum-arabic are dissolved in sufficient water for the purpose, and then thoroughly mixed with the alum-and-soap solution. This solution is then mixed thoroughly with the pulp, which is then finished into sheets of any desired size, in the usual way of finishing pulp-board; or the board may be made without the admixture of the solution named, and in the usual way. Then to render it fire and weather proof the board is immersed in a bath composed of the above named solution, and then dried in flat form, except those that are designed to be used for These are dried upon the forms employed to give them the correct curve or camber required. The size of the car being given, the sheets are made to fit without waste or cutting to fit after they are sent from the mill, except, perhaps, such fitting as may be made necessary by the position of doors and windows, and even this may be. avoided by giving the mill the correct diagram of the car, so that all the pieces may go right to place without trouble.
This sheathing will be foundvery durable and much less expensive than that ordinarily employed for the purpose, While much saving will be obtained in the weight of the car. This sheathing will also be found valuable in many other places besides on cars.
We are aware that the use of alum, soap, glue, and gum arable in the art of water and fire proof paper making is not new, and we therefore do not claim the same broadly.
What we claim, and desire to secure by Letters Patent, is-
1. As an article of manufacture, fire and weather proof sheathing madefrom pulp treated with the herein-described solutiois of alum, soap, glue, and gum-arabic before the same is finished into sheets, substantially as set forth.
2. The herein-described process of rendering pulp-boards fire and weather proof, which consists in soaking the finished board in the described solutions of alum, soap, glue, and gum-arabic, and in then drying the same in any desired shape for use, substantially as set forth.
In witness that We claim the above as our invention We hereunto set our hands this 20th day of June, 1882.
ROBERT FULTON. ALEXANDER DE LANO.

E. SGULLY, CHARLES J. HUNT.
