UNITED STATES PATENT OFFICE NAIL HOLDING BUILDING COMPOSITION Clarke F. Davis, Short Hills, N. J., asslgnor to American: Cyanamid & Chemical Corporation, New York, N. Y., a corporation of Delaware Application June 1, 1935, Serial No. 24,513

2 Claims. (01. 72-115) The present invention relates to a building In the drawing:

material. Fig. l is a sectional view of a building unit The principal object of the invention is the constructed according to this invention;

provision of a light, cheap building construction Fig. 2 is a partial perspective view showing a a unit, which will have superior nail holding qualimethod of waterproofing a core; 5 ties such as that of wood, although made Fig.,3 is a view similar to Fig. 2 showing an primarily of a cast composition. alternative method of water-proofing.

It has been proposed to make studding of such Referring now to the embodiment illustrated, a cementitious material as gypsum, hydraulic cenail holding core is shown at l which may be m ment, lime or concrete, but experience has shown of any shape and of any material which will have that units made of such composition have very these qualities, although wood is preferred bepoor nail holding qualities and nails driven therecause of its ease of working, availability and into have a tendency to loosen up under any sort cheapness.

This would not be true if the nail were 55 permitted any amount of movement or vibratlon.

While in the above specification certain cementitious compositions have been mentioned as the encasing material, certain water-proofing treatment has been mentioned. and certain nail holding compositions have been enumerated, yet it is to be understood that the invention is in no wise to be limited to these particular materials as they are mentioned merely as illustrative and the invention is to be construed broadly as directed to the combination of a nail holding core which is water absorbent either due to porosity. absorption, adsorption. or its cellular nature, treated either on its superficial surface or impregnated with a material which will prevent water being taken up by the core, the core and its treatment being encased in any watercontaining plastic mix which will take a set.

In like manner, the unit as a whole is not to be limited to studding. but is to be construed broadly as directed to any type of construction in which the above elements occur.

I claim:

1. As an article of manufacture, a nail holding core having on its superficial surface a sheet metal material impervious to moisture, and a surrounding nail penetrable set cementitious layer.

2. The article of claim 1 in which the encasing cementitious layer is gypsum.
