Abstract
Abstract The invention comprises securing means for flooring laid over a concrete base between opposite walls of rooms or halls. A set of metal channel casings is secured on the base in spaced relation with ends facing the walls. The casings have inturned top flanges and are overlaid crosswise by the floor boards. The casings each have a series of slidable sleeper sections on the inside in endwise succession. The ends of such series are spaced from the walls opposite them. The usual nails are driven slantwise through the floorboards into the sleeper sections to a point where the nails meet the metal bottom of the casings and are deflected to form endhooks under the sleeper sections, serving to retain the flooring to the same. The sleeper sections slide endwise when the floorboards expand laterally from damp weather, preventing the buckling of the floor.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
163 words
A sleeper construction for use in a wooden floor installation comprising in combination: a rigid base, a series of spaced, generally parallel elongated combination sleepers secured on said rigid base, a plurality of floorboards disposed transversely on said sleepers in substantially abutting relation and defining a flooring spaced above said rigid base, nails extending through said floorboards and having lower terminal bends anchoring said floorboards to said sleepers, said combination sleepers comprising elongated, channel-shaped rigid guide elements opening upward toward the undersurface of said transverse floorboards, and a plurality of relatively short-length, nail-penetrable elements supported by and received in said guide elements for free longitudinal reciprocation therein with a series of said floorboards anchored thereto by said nails whereby expansion and contraction of the floorboards transversely of said rigid guide elements is permitted by free reciprocation of said nailpenetrable elements without buckling of the floor, said rigid guide elements including means overlying said nail-penetrable elements for restraining them in the free longitudinal reciprocation.
Claim 2
Dependent Claim
163 words
A sleeper construction for use in a wooden floor installation comprising in combination: a rigid base, a series of spaced, generally parallel elongated combination sleepers secured on said rigid base, a plurality of floorboards disposed transversely on said sleepers in substantially abutting relation and defining a flooring spaced above said rigid base, nails extending through said floorboards and having lower terminal bends anchoring said floorboards to said sleepers, said combination sleepers comprising elongated, channel-shaped rigid guide elements opening upward toward the undersurface of said transverse floorboards, and a plurality of relatively short-length, nail-penetrable elements supported by and received in said guide elements for free longitudinal reciprocation therein with a series of said floorboards anchored thereto by said nails whereby expansion and contraction of the floorboards transversely of said rigid guide elements is permitted by free reciprocation of said nailpenetrable elements without buckling of the floor, said rigid guide elements including means overlying said nail-penetrable elements for restraining them in the free longitudinal reciprocation.
Claim 3
Dependent Claim
38 words
The structure of claim 1, in which said means overlying said nail-penetrable elements comprises inwardly directed flange portions extending inwardly above said nail-penetrable elements for retaining the latter in a path of linear reciprocation in said guide elements.
Claim 4
Dependent Claim
58 words
The structure of claim 1, in which said means overlying said nail-penetrable elements comprises inwardly directed flange portions extending inwardly above said nail-penetrable elements for retaining the latter in a path of linear reciprocation in said guide elements, and said flange portions comprising continuous flanges extending along the entire length of opposite, upper edges of said guide elements.
Claim 5
Dependent Claim
35 words
The structure of claim 1, in which said rigid guide elements include integral, lateral plates extending from the lower surface thereof, such plates receiving fastening means for anchoring said guide elements to the rigid base.
Claim 6
Dependent Claim
24 words
The structure of claim 1, said nail-penetrable elements being in endwise engagement for longitudinal impinging influence in the direction of said expansion and contraction.
