Abstract
Abstract A flooring system utilizing standard pattern conventional tongue and groove wood floorboards, the boards being supported on transversely disposed spaced channels, metallic holding clips securing the boards in bearing engagement with the channels, the boards being free from any special slots for clip engagement, the clips engaging the boards in a driven penetrating relation below the tongues and grooves in a manner which does not interfere with the tight vertical engagement of the tongues and grooves nor cause splitting of the boards, the clips engaging the channels each having a body portion vertically disposed between the boards below the tongues and grooves and having at the upper margin of the body portion a horizontally extending toothed portion driven in fiber-penetrating engagement into the board along the edge at locations wholly below the lower margin of the tongue on the tongue side of the board, and optionally, for greatly increased holding power having a penetrating portion extending into the groove side of the board below the groove.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
224 words
A flooring system employing standard pattern conventional wooden floor boards having side edge grooves and tongues engaging in said grooves comprising: a plurality of spaced parallel channels each with a pair or rims having upper and lower faces, a plurality of parallel floorboards having longitudinal edge grooves with tongues of each board in tight-fitting engagement in the grooves of contiguous boards at the top and the bottom thereof, said boards being transversely disposed above said channels and having lower faces engaging the upper faces of said rims, said boards having immediately below said grooves and tongues spaced vertical edge faces, said vertical edge faces below the grooves and tongues being vertically continuous and uninterrupted, a plurality of spaced holding clips, each of said clips having a vertically disposed body portion disposed between said boards wholly below said side edge grooves and said tongues and between said spaced edge faces, each of said clips having at the upper part of said body portion a horizontally extending toothed board holding portion extending directly from said body portion into the vertical edge of the board below said groove and tongue in intersecting relation to an edge face and each of said toothed portions being in fiber-penetrating relation therein, each of said clips at the lower part of said body portion being in gripped engagement with the channel.
Claim 2
Dependent Claim
224 words
A flooring system employing standard pattern conventional wooden floor boards having side edge grooves and tongues engaging in said grooves comprising: a plurality of spaced parallel channels each with a pair or rims having upper and lower faces, a plurality of parallel floorboards having longitudinal edge grooves with tongues of each board in tight-fitting engagement in the grooves of contiguous boards at the top and the bottom thereof, said boards being transversely disposed above said channels and having lower faces engaging the upper faces of said rims, said boards having immediately below said grooves and tongues spaced vertical edge faces, said vertical edge faces below the grooves and tongues being vertically continuous and uninterrupted, a plurality of spaced holding clips, each of said clips having a vertically disposed body portion disposed between said boards wholly below said side edge grooves and said tongues and between said spaced edge faces, each of said clips having at the upper part of said body portion a horizontally extending toothed board holding portion extending directly from said body portion into the vertical edge of the board below said groove and tongue in intersecting relation to an edge face and each of said toothed portions being in fiber-penetrating relation therein, each of said clips at the lower part of said body portion being in gripped engagement with the channel.
