square corners 23 of the notch 20 to bite into the side
sill ?ange surfaces and so anchor the ?ooring members
?rmly and tightly to the side sills.
Other ?ooring members may ‘be added consecutively to
those previously laid, with clips being interposed between
members as described to complete and secure the ?oor.
It may be appreciated that the clip shanks space the ?oor
ing members adequately and properly, since for the re
ception and retention of nails therebetween, the thickness
of the metal of which the clips are made is predetermined
by the desired spacing and the ?ooring members are drawn
tightly against the sides of the clip shank.
The desirability of the clips being hardened may be
readily understood. The corner edges of notch 20 effect

be handled expeditiously, and to put and secure the sub

example of such a sub-assembly is depicted in FIGS. 6

in FIGS. 8, 9, 10 and 11.
The ?ooring, as depicted in FIGS. 6—11 inclusive, is
of a different type than that shown in FIGS. 1-4 inclu
