WALL BOARD AND JOINT THEREFOR.

Application filed February 23, 1924. Serial No. 694,650.

To all whom it may concern:

Be it known that I, HARRY F. ADAMS, residing at Greenport, county of Suffolk,

' State of New York, a citizen of the United States, have invented. certain new and useful Improvements in Wall Boards and Joints 'Iherefor, of which the following is a specification.

This invention relates to wall boards and joints for joining the edges thereof together. The increased use of wall boardfor walls and ceilings has emphasized the value and utility of the same. The present objection to its use is that the use of strips of wood or metal is necessary to cover up the nail heads which are used to secure the board in place. Any attempt to countersink the nails, will cause the weakening of the wall board structure. In addition to this condition, the edges of the board have been so constructed as to make a proper joint difficult if notinipossible.

The primary object of the 1present invention isto so construct a wal board edge, that nailshaving large heads may be driven securel through the edge of the board and whose eads may contact with but not enter the surface, the outer edge of the nail head being inward of the outer surface of the board.

Another object of my invention is the provision of edges on wall boards and a joint therefor, the edges being so constructed that the material of the joint will be keyed in place between the two edges.

Referring to the drawings, where I have illustrated various preferred forms of my' invention,

Fig. .1 is a sectional perspective view of my improved wall board edge and joint therefor.

Figs. 2 to 4 are similar views of various modified forms of the invention.

Referring to Figure 1, 10 and 11 represent adjacent wall boards. In place of the usual edge, I have provided a special construction having a surface 12 at a substantial angle to the outer surface of the wall board, 11. From the bottom of this surface is a surface 13 which is utilized as a nailing surface. At the edge of the-nailing surface is a surface 14 which is undercut in a manner similiar to the undercut showing of the surface s 12. A nail 15 having a head 16 is illustrated as contacting with the surface 13. .This

head does not injure the structure of the wall board and yet is entirely inward of the outer surface of the'board.

In a similar manner, the surfaces 17, 18 and 19 are provided on the wall board 10, the nail 20 having a head 21 being entered into the wall board at the surface 18 and driven through into the stud or other support 22.

The space between the plane of the outer surfaces of the boards 'and'the stud or other support 22 and between the two adjacent edges of the wall board is filled with a suitable filler 23, such as plaster, the outer surface being smoothed to make it flush with the wall boards.

It will be noted that in the construction shown in Fig. 1, the part 25 and the part 24 of the filler which are respectively inward andoutward of the edge between surfaces 1 1, 13 and 18, 19, are both key shaped and are prevented by their structure from falling away. In addition to the key shape, the 1 heads of the nails if properly shaped and driven, may also become keys which will outer surfaces of the boards. This, of course, makes a corresponding change in the outer portion 24: of the filler 23 InFig. 3, the parts 10, 11 13", 14", 15 16", 18 19 20", 21 22 and 25 correspond to similar parts'of Figs. 1 and 2, it being noted that the surface 13 joins the outer surface of the board 11 and the surface 18 joins the outer surface of the board 10", causing a corresponding change in the shape of the part 2 1" of the filler 23*.

In Fig. 4:, I have shown the boards 10 and 11. Between the upper and lower surfaces of these boards, I have provided surfaces 13, 18 having sections in the shape of an ogee. The nails 15 and 20 are driven in these ogee surfaces through the adjacent portions of the boards and into the stud or other support 22. The filler 23 is held in place between the two boards in a manner similar to the filler 23 of Fig. 1.

In any or all of these forms, the surfaces may be suitably sized or roughened or both before the filler is laced.

It will thus be c ear that I have provided stantially at rightangles to the plane of the i an edge for a wall board through which a nail may be driven without injury to .the wall board structure and which edge when adjacent a similar edge will provide a secure these are merely illustrative and that other modifications and changes may be made without departing from the spirit of my invention and within the scope of the appended claims.

Having described my invention, what I claim is 1. A manufactured wall board sheet having two parallel surfaces in its two greatest dimensions and a surface at the edge of the board, the surface at the edge of the board having a slanting relation to the parallel surfaces and means for holding a plastic material on the slanting surface to form acontinuous surface between the adjacent edges of the exposed surfaces of adjacent boards when in place.

2. A manufactured wall board sheet having two parallel surfaces in its two greatest dimensions and a surface at the edge of board having a slanting relation to the parallel surfaces and an undercut portion adjacent the slanting surface for holding a plastic material on the slanting surface to form continuous surface between the ad- 5 jacent edges of the exposed surfaces of adj acent boards when in place.

3. A manufactured wall board sheet having two parallel surfaces in its two greatest dimensions and a surface at the edge of the board having a slanting relation to the parallel surfaces and an undercut portion adjacent each side of the slanting surface for holding a plastic material on the slanting surface to form a continuous surface between the adjacent edges of the exposed surfaces of adjacent boards when in place.

4. In combination the frame of a house,

and inner surfaces and a space adjacent the Y edges of the nailing surfaces ofand between the adjacent edges of adjacent sheets and a hardening plastic means for filling the space between adjacent sheets.

5. In combination the frame of a house, manufactured wall board sheets extending between portions of the frame and having edges extending along portions of the frame, the wall board sheets having nailing surfaces at an angle less than a right angle to the surface next to the frame, and a means for filling the space between the two adjacent edges of adjacent wall board sheets, connecting the outer surfaces thereof and covering the nailing surfaces.

6. In combination, the frame of a house, manufactured wall board sheets extending between portions of the frame and having edges extending along portions of the frame, the wall board sheets having sur faces at their edges making acute angles with the respective surfaces adjacent the frame and between the outer and inner surfaces of the wall board sheets, a hardening plastic means filling the space between adjacent sheets, the adjacent edges of adjacent sheets having surfaces coacting with the filling means to hold the latter 1n place.

In testimony whereof I hereunto aflix my signature.

HARRY F. ADAMS.
