WALL CONSTRUCTION.

Application led January 30, 1925. Serial No. 5,698.

This invention relates to a wall or partition construction for buildings, being particularly concerned with the method or steps employed in connecting wall boards to supports therefor in such manner that the resulting surfaces will be suitable for direct application thereto of a decorative material and with the means for securing the wall board in place to form a strong, easily erected, and smooth wall. It is accordingly an object of my invention to secure the wall board in place non-defaceably, and bymeans which may be readily and inexpensively produced and installed.

Another object of my invention is to produce a strong` smooth wall. so constructed as to be available for practically immediate use Without plastering or mortaring, and

having a very high percentage 'of salvageable material.

The wall construction with which my invention is particularly concerned is preferably fire-proof. It makes use of three principal constituents, viz, (1) sheet metal studdings, or other supports, (2) wall boards produced from a composition of plaster, fibre, asbestos, or otherwise, and (3) means by which the boards are secured to the studdings or supports either adjacent the board ends or intermediately thereof. It is particularly with the manner in which such fastening means are applied in place,

that the present improvements havev to do.

Other objects and purposes of my invention will appear hereinafter from the speciication and claims and from the accompanying` drawing wherein- Figure 1 is a sectional perspective view of a partition constructed according tothe present invention;

Fig. 2 is a horizontal section through a portion of such partition;

Fig. 3 is an elevation of a punching tool which prepares the board and studding for the reception of the fastening. means;

Fig. 4 is an enlarged detail in section through the board and studding showing the tool inserted therein; and

Fig. 5 is a similar view with the fastening means in place.

In the several figures of the drawing the studdings are designated asl A andthe wall boards as B. Adjacent the floors, ceilings, outside walls, etc., the studding construction may be modified to suit particular requirements. For example, a channel track 6 may be used advantageously 'adjacent the floor and ceiling, a half stud 7 adjacent an outside wall or at the intersection of two partitions, and at a partition corner a special stud .8, such as is shown in Fig. 2, may perhaps be employed to advantage. lin all such cases, however, the sheet metal character of the support is preserved, so that the problem of connecting the wall 'boa-rds thereto remains the same.

Referring n'ow to Fig. 3, I have shown a tool in the form of a punch having a handle 10, one end 11` of which is adapted to receive blows from a hammer or other instrument. Projecting from the opposite handle end 12 is a shank 13 which terminates in a point 14. With such a tool ll am able to pierce a hole through the body of a wall board and metallic support upon the rear side thereof. In performing this operation the tool reaches a nal position. such as appears in Fig. 4, where its pointed end is shown as having formed or displaced inwardly a portion of the support body to form a lip 15 which surrounds the aperture thus made. Adjacent the handle end 12 is a fillet 16 which acts to crush slightly the outer face of the board when the tool is driven in to its intended limit. 'llhe driving of the tool to this position is, of course, accomplished with rapidity following which it is withdrawn and applied repeatedly to other places where additional holes may be desired.

The upright studding used is preferably box-like, to secure the necessary strength and rigidity under the above described piercing operation. rll`he term box-like, therefore, as used in the specification and claims, indicates studding strong enough and rigid enough to withstand the stresses of the piercing operation.

After preparing holes in the boards and metallic supports in the manner above eX- plained, fastening screws are inserted. Each screw is formed with a threaded shank 17 having one end pointed as at 18. its other end being formed with a head 19 which is preferably flat andnconical, asshown. -`The hole resulting from the insertion -`of. the punch is substantiallythe size. ofthe screw shank so that the screw threads will take; a. i

tight hold upon the surrounding parts. This is true particularly of the sheet metal studding with whose lip the screw threads effect a very secure engagement. As the screw is tightened there is a tendency to draw this lip back towards its 'original position with the result that I obtain a most secure connection between these parts.

With advancement of each screw to final osition, its head 19 Will be pressed into the Ecard until its flat end is flush with the face thereof. As the result of employing a screw having these characteristics, I provide means for fastening at desired places the several boards to the studdings, or other support, in a non-defaceable and unobtrusive manner. The tire-proof characteristics of such a wall and partition are preserved intact, and in addition it becomes unnecessary to incur the heavy additional expense of applying thereto a coat of plaster. To such a Wall or partition decorative material may be directly applied, the joints, screw heads, etc., being readily concealed by putty in the usual manner.

I claim:

1. The method of constructing a wall comprising a boxlike metallic support, a composition Wall board adjacent thereto, and a Hat head screw connectin one with the other, which consists in erecting the board adjacent rial surrounding the hole to connect the board to the support and the screw head being receivable Hush within the crushed surface of the board, substantially as described.

2. A Wall construction comprising a hollow box-like metallic studding, a composition wall board adjacent the studding, said wall board having a countersunk hole therethrough, said studding having a hole adja- Y' cent the wall board hole, and a securing dcvice passing through the holes and detachably securing the board to the studding and seating in the countersink in flush relation to the outer face of the board.

3. A wall construction comprising a hollow box-like metallic studding, a composition Wall board adjacent the studding, said wall board having a countersunk hole therethrough, said studding having a hole adjacent the Wall board hole, and a fiat headed securing screw passing through the holes, the screw threads engaging the studding and the screw head seating flush with the outer .i'ace of the board.
