.a .Irame having slots on the inner faces of‘ the
frame members "in which ‘the ends of ‘the spring
strips may .projec't. lNails are driven through

I have illustrated the frame 10' comprising
longitudinally disposed members

lmenibers l2, ‘the inner .iaces .[3 of which are
provided with a‘slot ‘M. The end‘mem‘bers [2
have a. dowel 15 on their ends ‘which "project
into the slot M von the‘memhers H to. secure
the members in aligned ‘?xed relation. Gusset
plates It may be disposed .in the slots lat] each
of the corners to further strengthen the frame.
f‘ The longitudinally extending members Ll have
pairs .‘l'! of nails 1.8:, or similar pin-like elements,
disposed in spaced relationand aligned on’ op
posite sides of the frame. ‘ The nails project up
wardly .from the’ bottom or the frame, through
the slots, into the upper portion of the’ mem
bers. .Preferably ‘holes are'ldrilled through the
lower ‘half of the members ‘by using. a layout
?xture, after which the nails are driven intojthe
holes, through the slot into the upper ‘portions
of the members.
In a similar manner, individual
nails 2.2 are provided in the ‘end members 12
for a purpose which will he explained herein
