B'ULDING BOARD.

Application tiled may 9, 1921.

T 0 all whom, it may concern: l

Be it known that ll, HERBERT Sononrmrn, a citizen oi' the United States. residing at Los Angeles, in the county of Los Angeles, State of California, have invented new and useful Improvements in Building Board, of which the following is a specification.

My invention relates to building board, and is especially designed to be secured to the frame work of a building to serve as an outside wall or siding therefor, as well as to provide a lathing surface to which a tinish coating of cement or plaster may be applied; said board being so constructed that it may be quickly and easily applied and will form an adequate insulation from the effects of heat, cold and moisture.

Other objects will be apparent from the following description, will be pointed out in the claims and will be embodied in the accompanying drawings, in which:

ig. 1 represents a face view of a building board panel constructed lin accordance with my invention.

Fig. 2 is an enlarged vertical section through a portion oi the same..

Fig. 3 is an enlargement of a fragment of lFig. 2 showing more clearly certain details of construction.

Fig. 4 is a perspective view of one of the binding members, showing its application to some of the structural units which are illustrated in dotted lines.

lF ig.- 5 is a view similarto Fig. 3 showing la moditiedorm of the building board.

lin carrying out m invention re resents a building boar panel ci any desired length and width, which comprises an outer wall` 11 and an inner wall 12, spaced apart and heldin such spaced relation by means of a plurality oi tie and spacing members 13.

The outer wall 10 comprises a lurali oi vertically disposed wires orros 11tw ich are spaced equally apart in parallel relation and having resting upon their outwardly disposed surfaces a metallic lathing formed of woven wire or expanded metal.

The inner wall 12 comprises-a plurality of horizontally disposed rods or wires 16 spaced apart in parallel relation, a sheetoi building paper 17 disposed on one side thereof` and an outer sheet of asphaltmnl disposed on the opposite side thereof," which are secured together by a filling of pitcho 19 interposed therebetween and encompassing said wires.

Serial No. 468,060.

The tie and spacing members 13 are preierably formed of a wire which is twisted to form a loop 2O at one of the ends through 'which the wires 16 pass, a loop 21 adjacent lts opposite end through which the wires 14 pass, and an intermediate spacing loop 22. The ends 28 of the wire forming the member 13 extend beyond the loop 21 and serve when twisted together to bind the metallic lathing 15 to the rods or wires 14E as clearly shown in the several figures of the drawing.

By the above recited construction it will be seen that l have provided a building board composed of two oppositely disposed wallsI spaced apart, one of said walls 12 adapted to rest against the studding of the building, and being formed of insulating material, and the other wall 11 being formed of ai lathing to which an outer surfacing and inishing material of cementor the like, may be readily applied after the boards have been secured in place. ln order that strength and body may be given to the board, l propose to till the space between the walls 11 and 12 with plaster or cement 2d; this may be done during the process of manufacture of the board previous to its being applied to the building as shown in Figs. 1, 2 and 3 of t-he drawings; or the board may be initially prepared as shown in F ig. 5 of the drawings and the plaster or cement filling 24 applied during the process ot applying the board, and if so desired, may be omitted entirely from the construction.

The asphaltum sheet 18 is preferably of larger area than the body of the panel 10 and is adapted to extend beyond said body portion adyacent two oi its joining edges as shown in lFig. 1 ofthe drawings, in order that an overlapping at the joint between the panels may be had, when they are placed in position on the building, and the lathing material 15 is also arranged to overlap the body of said panel at two of its adjoining edges for the same purpose.

ln order that the plaster hlling 2d may be reeniorced when in a. lastic condition. and to prevent the breaking of the panel when the paster is in such plastic condition. ll place a plurality of strips of building paper 25 under each of thewires o r rods 14., thus the panels may be conveniently handled before the Jplaster has become thoroughly7 dried, without injuring the same.

What ll claim is:

1. A building board, comprising a pair titl Mib

lll@

of oppositely disposed walls, one of said walls forming a lathing surface and the other of said walls being formed of an insulating material, means for holding said Walls together in spaced relation, and a plastic filling completely filling the space between said walls.

2. A building board, comprising a pair of oppositely disposed walls, each of said walls being composed of a plurality of wires arranged in parallel relation, the wires of one of said walls being embedded between an insulating material an'd the wires ofithe other wall bein provided with a lathing surface, means iior securing said walls together in spaced relation, and a plastic filllng completely filling the space between said Walls.

3. A building board, comprising a pair of oppositely disposed walls, each of said walls being composed of a plurality of wires arranged in parallel relation, the wires of one of said walls being interposed between sheets of-insulating material bound together, the wires of the other wall having secured thereto Aa metallic lathing, a plurality of binding members adapted to bind lSaid Walls together in spaced relation, and a plastic material completely filling the space be#y Y tween said sheets for embedding said wall wires, and a plaster filling interposed between said walls. y

In witness that I claim the foregoing I have hereunto subscribed my name this 15th day of April, 1921.
