l claim as my invention:
1. In a rack for storing elongated objects in
a vertical position on a base and within a recess
in the front of a horizontal member forming part
of the rack, in combination, a shaft disposed for I
rotary motion on the horizontal member on an
axis substantially normal to the member, a pen
dulous depending projection on the rear end of
the shaft rigidly secured thereto and tending to
hold the shaft in a given angular position, a pen
dulous arm projecting at right angles from the
front end of the shaft, said arm falling in a plane
normal to the plane de?ned by. the shaft and the
pendulous depending projection, said pendulous
arm’when in horizontal position falling in front
of the recess in the horizontal member, and
means for limiting the "rotation of the shaft
through a right angle so that when the pendulous
arm is in horizontal position the pendulous de

the object in the recess, said rear crank arm being‘
positioned with reference to the frontcrank arm
to bias the front crank arm to a horizontal p081‘.
4. In a rack for storing and securing elongated
objects within aligned positions in a pair of par
allelly disposed members forming part of the rack,
_ in combination, a bell crank lever pivoted on an
axis normal to one of the parallelly disposed
members and having its crank arms falling in
parallel planes spaced from each other at a dis
tance slightly greater than one of the parallelly
disposed members so that one crank arm falls
behind and the other crank arm falls in front of
the member to which the bell crank lever is piv
oted, the pivotal positioning of the bell crank
lever being such thatthe crank arm falling in
front of the member when in one position also
' falls across the recess in one of thevp-arallelly
disposed members so that any elongated object
disposed in the recess is held in the recess, the
crank arms being angularly so disposed with ref
erence to the pivot axis that the front crank arm
is always biased to said one position.
