Description
HARRY W. IFEIL, 0F CHICAGO, ILLINOIS.
STOVE-BOABD.
Specification of Letters'Patent.
Patented Aug. i, 1916.
. Application led November 29, 1915. Serial No. 63,9381.
To all whom 'it may concern:
Be it known that I, HARRY W. PFEIL, a citizen of the United States, residing at 3960 Broadway, in the city' of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Stove-Boards, of which the following is a specification.
My invention relates to improvements 1n boards upon which stoves or like articles may be mounted andv more particularly to devices of this character which are constructed of light and fire proofed material.
The objects of my invention are to produce an elhcient, very cheap and exceedingly simple device of wood or other similar material and to so cover and coat the top surface and edges of the material of the device that it is rendered practically fire and moisture proof and also provided with a durable finish of pleasing and polished appearance.
These and other objects I accomplish as hereinafter set forth in the following description and as more particularly pointed out in the appended claim, reference being had to the accompanying drawings in which an embodiment of my improvement is illustrated.
In the drawings, Figure l, is a top plan view of my improved device, sections being broken away at one corner thereof to show the various layers forming the composite board Fig. 2, is a transverse section through the board on line 2 2, Fig. 1.
In referring to the embodiment of my 1nvention shown in the accompanying drawy ings in detail, like numerals designate corresponding parts.
My improved board as shown comprises an intermediate layer l, and two other layers 2 and 3, between which the intermediate layer is interposed and firmly cemented, the thin layers being superimposed upon each other to form a flat strong composite board of considerable thickness.
The thin layers preferably are left rough surfaced just as they come from the saw, not being planed, smoothed or finished in any way, thus considerably lessening the cost of manufacture and providing a fairly rough surface for the cement.
I prefer to make the intermediate layer l, of fairly soft wood and about three times as thick as the outer layers and to arrange it so that its grain is about at right angles to the outer layers to prevent warping or splitting.
The outer layers 2 and 3 are preferably of harder wood and are perhaps made thin enough to be termed veneers.
To protect the composite board from the stove or other articles mounted upon it, I cover the top surface and side edges of the same with a thick coat of fire proof composition. In fact in some instances and for some purposes I may cover both the top and bottom surfaces with the fire proof coating but for ordinary use the bottom is protected sufliciently by the floor upon which it is placed. The composition employed by me preferably consists of the following ingredients mixed in approximately the proportions stated: plaster of Paris, 25 per cent.; fireproof cement, 35 per cent.; asbestos, 25 per cent.; shellac, l5 per cent. These ingredients are mixed to about the consistency of a fairly thick paint and then applied to the surface of the board in any suitable manner. A fairly thick coat is preferable as it provides a better and more durable protection. After the board is covered it is placed where the covering 'can set and dry. Any suitable fire proof paint may also be included-in the composition in order that a finished surface of any desired color may be produced.
As shown in Fig. 2 of the accompanying drawings, the thick coating 4f, of fire proof ycomposition is spread evenly over the top surface of the board and is also placed upon the edges as indicated at 5, thus protecting both the top and exposed edges from fire and also from moisture.
My improved board can be used for a variety of purposes but is principally adapted to be placed beneath a stove.
hile I have illustrated and described a preferred form of construction for carrying my invention into effect this is capable of a wide range of variation, alteration, modification and change without departing from the spirit of my invention. I therefore do not wish to be limited to the construction herein shown and described, but desire to avail myself of all such variations, alterations, modifications and changes as fairly fall within the scope of the appended claim or may be construed to be within the scope hereof by involving the doctrine of equivaents.
What I claim as my invention and desire layers7 and a heavy covering of fire-proof to secure by Letters Patent is composition upon the exposed top and edge 10 A board of the class described, comprising surfaces of the board. an intermediate layer of fairly thick soft Chicago, Illinois, November 24th, A.

Copies of this patent may be obtained. for five cents each, by addressing the "Commissioner of Patents, Washington, D. C.
