However, there is suflicient clearance between the ver
leg engaged with said upright member and extending
tical edges of the bearing leg 144 and the respective
longitudinally thereof, with at least a lower corner of
bearing walls to enable the bracket 138 or 139 to be

pivoted or swung laterally outwardly from the support
front and rear walls of said member, and with at least
an upper corner of said bearing leg bearing against a por—
tion of the other of said front and rear walls, and a
ing member 136, when there is no load on the arm 146,
without the necessity of sliding the bracket 138 or 139
upwardly past the upper end of the upright member 136.
It is particularly advantageous to have the connecting
leg 146 substantially perpendicular to the bearing leg
144.
In this instance, an upper portion of the connect

ber and having a tang with a portion parallel to said
10 connecting web and spaced therefrom to engage a por

arm 140 to be borne by the member 136 closer to the
arm. The bracket 138 or 139 can then be easily pivoted 15 direction with respect to said supporting member.

edge of the bearing leg 144 as a pivot line.
Additional modi?cations of the invention will be ap
parent to those skilled in the art and it is to be under

parting from the scope of the invention as de?ned by the
appended claims.
