INTERLOCKING FLOORING AND CEILING.

Specification of Letters Patent. Patented Sept. 28, 1909,

Application filed June 30, 1908. Serial No. 441,084.

useful Improvements in Interlocking F loor ing and Ceiling; and I do hereby declare the i following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in interlocking flooring and ceiling, and the object of my invention is to provide tongued and grooved flooring and ceiling so made that the parts maybe easily fitted together to form an absolutely tight joint at the top.

With this object in view, my invention consists in the construction and combinations of parts as hereinafter described and claimed.

In the accompanying drawingFigure 1 represents an end elevation partly in section, showing partof a fioor made in accordance with my invention. Fig. 2 is a similar view showing the method of putting the flooring together. a represents a sub-floor or sill, and 6- strips of flooring. Each strip is provided with a tongue 0 on one side located preferably below the center thereof, and a groove d on the other side, arranged at about the same height, but slightly larger than the tongue 0. The bottom of each strip 6 is beveled off, as shown at -e. The strips are secured in position by means of nails f, driven in diagonally in the usual way. The advantage of thisconstruction is that after one strip has been nailed in position, the next strip may be easily fitted against it by tilting it, as shown in Fig. 2, the beveled 01f portion e permitting such tilting movement, and then' pushingthe second piece snugly up against the first piece, as shown in Fig. 1.

This forms an absolutely tight joint at the top, as shown in Fig. 1.

WVhile I have shown and described a beveled under lip in combination with a loose fitting tongue and groove, it is apparent that a beveled under lip is equally applicable and advantageous in combination with a tight fitting tongue and groove.

Having thus described my invention, I claim l. A flooring or ceiling strip provided with,

the ordinary tongue and groove, but with the lip under the groove made less in thickness than the distance between the tongue and the sill by beveling off the entire under side of the under lip of the groove, said beveled surface being wider than the tongue, substantially as described.

2. A floor or ceiling composed of strips each provided with the ordinary tongue and groove, but with the lip under the groove, as laid, made less in thickness than the distance between the tongue and sill by beveling off the entire under side of the under lip of the groove, said beveled portion being wider than the tongue, substantially as-described.

3. A floor or ceiling composed of strips each provided with the ordinary tongue and groove, but with the groove deeper than the width of the tongue, and with the lip under the groove, as laid, made less in thickness than the distance between the tongue and sill by beveling off the entire under side of the under lip of the groove, said beveled portion being wider than said tongue, substantially as described.

In testimony whereof, I aflix my signature, in presence of two witnesses.
