I SAMUEL R. SHOUP, OI WEEHAWKEN, NEW JERSEY.-

SHEATHING BOARD.

Application filed January 20, 1922. Serial No. 530,715.

T all whom it may concern:

Be it known that I, SAMUEL R. SHoUP, a citizen of the United States, residing in the city of Weehawken, State of New Jersey, have invented a certain Sheathing Board for Use 'in Constructing Buildings and Other Uses, of which the following" is a specification.

This sheathing board is amanufactured product of strips of wood, sheets of manufactured board, wire, tar and staples. It is the support and backing for concrete, plaster or veneer. It is nailed direct to the studding and frames of buildings and is also the backing for concrete floors. It is used in the manufacture of packing cases.

The sheets of backing board are made of different substances to meet the various requirements of the purchaser; it is preferably made of asbestos or of pulp mixtures having a large percentage of asbestos or other fire resisting materials. The asbestos boards coated with tar keep the walls dry and air-tight, the wood strips being imbedded in concrete and backed with the asbestos board make the wall almost fireproof. The strips of wood are sawed preferably with beveled sides and mounted on the board with the smaller side against the board; the large side facing out, makes dovetail spaces in which the concrete locks itself securely in place.

My invention is fully shown in the accompanying drawings in which Figures 1, 4, 7 9 and 10 are end sections of small pieces of my improved sheathing board. Figures 2, 3, 5, 6 and 8 are plan views of the same.

In the drawings, Figures 1, 2, 3, 7, 8 and 9, wood strips (1) are shown bound seac curely together by several pairs of parallel wires (2), the wires being twisted together between each pair of wood strips. In Fig.

2 wood strips are shown parallel to each other and at right angles to the binding wires and edge of the board. In Figures 3, 5 and 8, the wood strips are shown mounted obliquely to the wires and edges of the board; this arrangement of the strips makes a strong brace for the studding.

In Figures 1, 2 and 3, the web is composed of strips (1) and binding wire (2), mounted on and pressed into the plastic tar coating (3), which is applied to the asbestos board (4) while hot. Since asbestos @5 board has little tensile strength, the backing wires (5) are placed behind the asbestos board (4) to support it, wire staples (6) are driven over the wires (5) through the asbestos board (4) into the. wood strips.

In Figures 2, and 5, 8 the backing board (4) is shown cut wider than the strips (1) at (a). This is to allow the backing board to lap under the edges of next width of board to make tight joints.

In Figures 1' and 2 the concrete (10) is shown keyed in behind the beveled strips and twisted wire, it being held securely in place.

Figure 3 is a plan view of Figure 1. It differs from Figure 2 in that the binding wires (2) cross and bind the strips diagonally to the line of travel of the said binding wires. The edges of the sheathing board are cut parallel to the travel of the binding wires.

Figure 4 is an end section; and Figures 5 and 6 are plan views .in which the wood strips (1) are spaced much farther apart than shown in Figure 1. Expanded metal lath (7) or wire mesh is stapled (6) to the wood strips 1). The concrete hardens and fastens itself between the metal lath (7) and the water-proofing material The back (4) is held between the strips (1) and the back wire (5) by wire staples (6) being driven over the back wire (5) through (4) and into the strips (1).

igure 5 is a plan view of Figure 4. The strips are placed at an angle to the wires (5) and the edge of board for bracing purposes.

Figure 6 is a plan View of Figure 4. The strips (1) are horizontal to the vertical wires (5).

Figure 7 is an end view and Figure 8 a plan of Figure 7. Wood strips (1) are arranged horizontally to edge of paper; the strips are bound together with binding wires (2). The board (4) is coated with tar A heavy sheet of paper (8) is pressed to the tar making a three-ply board. For additional water-proofing protection tar is also applied to the reverse side of the board, the wood strips (1) are pressed into the tar, staples (6) are driven thru the paper (8), tar (3), board (4), into the wood strips (1). Paint (9) is applied to the paper In this arrangement of the sheathing board the wood strips are nailed against the studding, the painted sheet (8) to the Ou s of building. This sheet is painted as it is the outside of the building and exposed to the weather.

Figure 8 shows the wood strips (1) mounted at an angle to the binding wires.

Figure 9, end section, the wood strips (1) bound by wires (2) twisted between each pair of strips. The strips are pressed into the coating of plastic tar (3). The tar cements the strips to the backing material (4).

Figure 10 shows the beve ed strips (1) cemented to the board (4) with tar (3), and stapled with staples (6).

Having thus described myinvention I claim and desire to secure by Letters Patent:
