' sra'r BENJAMIN WOUDHOUSE, 0F SEATTLE, WASHINGTON,
PLASTEE, BOARD.
Application filed August 2t, 19%. Serial he. 733,521.
To all whom it may concern:
Be it known that I, BENJAMIN Woon- HoUsn, a citizen of the United States, and a resident of Seattle, King County, Washington, have invented certain new and useful Improvements in Plaster Board, of which the following is a specification.
This invention relates to improvements in plaster board and similar sheets of plastic composition such as may be used in building construction in lieu of the usual lath and plaster, or outside cement or stucco finish; more particularly the invention relates to the reinforcing of sheets of plaster board, or the like, so as to prevent chipping, cracking, or breaking before and after being put into use.
It is the principal object of this invention to provide reinforced plaster board that will be relatively inexpensive to manufacture, that is light in weight yet durable in use and which embodies reinforcing that will prevent the usual cracking or chipping ofi of the edges during transportation and handling and which further provides for nailing it to a wall without chipping.
It is also an object, of the inventionto provide plaster board of the above character wherein the body portion is strengthened by the embedding therein of woven wire netting and the edge portions are protected and also reinforced by the embedding therein of galvanized, sheet metal strips of angular form in cross section and slotted for the reception of nails whereby it may be secured in place;
A still further object resides in the provi sion of reinforcing strips for the edges of plaster board sheets having upturned edge flangesv embedded in the sheet for the purpose of adding rigidity and which further serves as a means to which the ends or edges of wires for reinforcing the body 'may be attached and held in place while the plastic material is being molded.
lln accomplishing these and other objects of the invention, have provided the improved details of construction,the preferred.
forms of which are illustrated in the accompanying drawings, wherein Figure 1 is aside view of a plaster-board embodied by the present invention; a; part of which is broken away to better illustrate the reinforcing thereof. I a
Figure 2 is an enlarged sectional view of the edge portion of a board, showing the re nettin in inforcing strip and attachment of the wire netting thereto.
Figure 4 is a perspective view of a part of a reinforcing strip.
Referring more in detail to the drawmgs 1 designates, in its entirety, a plaster board embodied by the present invention. Such boards may be made in various Widths and lengths convenient for use and from any suitable plastic composition such, for example, as a mixture of plaster and fibrous material.
The present board, or sheet, is reinforced throughout its body portion by a strip of woven wire netting, designated at 2, which is embedded centrally between the opposite side faces of the board. Along its longitudinal edges, the board is reinforced by the embedding therein of strips 3, preferably of galvanized'sheet metal, as best shown in Figure 2. The netting 2 is supplemented by heavy wires 4 extended lengthwise of the board in spaced apart relation.
The principal feature of the present in-- which nails 9, or the like, ma be driven to secure the board to a wall. uch reinforcing strips make possible the nailing of the boards securely and permanently in place without danger of chipping or cracking along the edges.
In the making of such boards, the binding strips 3 are first arranged along the opposite side edges of a mold, a layer of plastic material is spread in themold, the strip of wire netting is then laid thereon and it is of such width that its edges will overlap the binding strips 3 and the Wire ends, as designated at 10, are bent laterally to hook over the flanges 7' to thereby hold the place While the board is being molded. This method of construction also adds strength to the board and prevents de roe tachment of the binding strips after the matively terial has, set. After so attaching the ends 10 to" the strips,
the final layer of plastic material is added,
and the board allowed to set.
the material is. struckinwardly to form the flanges 14 to Which the Wire netting may be attached by hooking the ends 10 thereover.
Having thus described my invention, what I claim as new therein and desire to secure by Letters-Patent, is:
1. A plaster board comprising a body of plastic composition, a rigid reinforcing strips of channel form,ernbedded therein along its edges having a slot for the reception of anchor nails; said strips comprising relawide base flanges lying flush with a face of the board with a laterally turned flange at one edge overlapping the edge of the board and a laterally turned flange at its other edge embedded within the board.
'2. A plaster board comprising a body of plastic composition, a rigid channel form reinforcing strip embedded therein along 1ts edge; said strip comprlsing a relatively wide base flange lying flush with a face of the board and a laterally turned flange at its inner edge embedded within the board and a laterally and a strip of woven wire netting embedded in the board to reinforce its bod portionin adapted to register when assembled forbod of the reception of nails, or the like.
4:. A plaster board comprisinga plastic composition, rigid angular rein orcturned flange at its other edge overlapping the edge of the board,
ing strips embedded therein along its edges;
said strips each comprising a relatively wide base flange lying flush with a face of the board and provided with inwardly struck portions forming anchor flanges and leaving slots for the reception of anchor nails, or the like, and an inwardly turned flange along the outer edge ofthe base flange overlapping the edge of the board, and a strip of wire netting embeddedin the board to reinforce its body portion and having the wire ends along its edge hooked over the inwardly struck flanges of said strips. Signed at Seattle, King Count ington, this 3rd day of July, 1924.
