modified form of the fastener being inserted
in these kerfs 18 and the teeth 10 on the
arms preventing the withdrawal of the arms
in a manner which has been explained. The
5 heads 6 of the modified form of the fastener
are disposed in recesses 19 in the sides of
the members 11, the teeth 7a extending into
the members 11 to hold the fasteners and
the transverse member 17 in place.
10 In constructing the frame 13, the fasten-
ers are driven into the upper and lower ends
of the members 11 and the two fasteners of
the modified form are secured to the trans-
verse member 17 as has been described.
15 The fasteners, which have been secured to
the ends of the members 11, are then dis-
posed in alinement with the kerfs 15, and
the heads 6 on the fasteners, which have
been secured to the transverse member 17,
20 are disposed in alinement with the recesses
19 in the members 11. The members 11 are
then driven toward each other, clamping
the members 12 and the transverse members
17 therebetween.
25 Having thus described my invention, I
claim as new and desire to secure by Let-
ters Patent:
1. In combination with a member havingkerfs extending through opposite sides, a
joint fastener having two arms spaced from 30
each other and disposed in the kerfs respec-
tively, teeth on the inner edges of the arms
for engaging said member, each of the arms
being adapted for holding its companion
arm in one of the kerfs of the said member 35
respectively, and means by which the joint
fastener may be secured to another member.
2. In combination with two members hav-
ing kerfs, a joint fastener having a head
with teeth, the head being disposed in the 40
herf in one of the members, with the teeth
engaging the member, two arms secured to
the head, spaced from each other and dis-
posed in kerfs in opposite sides of the other
member, and teeth on the inner sides of the 45
arms for engaging the last-mentioned mem-
ber, each of the arms being adapted for
holding its companion arm in a kerf in the
second-mentioned member.
In testimony whereof I have signed my50
