spaced apart, a relatively long handle, a support
for said arms disposed at one end of said handle
so that the upper ends thereof will be free, an
arcuate jaw member ?xed to said free end of each
able length for the convenience and-e?iciency.
To pivotally move the rigid member 29 as above
described in a clockwise direction to close the
jaws I4 and I5 we provide the rod 40 with a pair
spring arm, said jaw members being in opposed
relationship and adapted to clamp and hold be
tween them the elongated glass tube of said fluo

urged towards each other, and means for causing
said spring arms to move toward each other, said
last named means comprising a substantially hori
zontally disposed rod member having one end
of spaced ?xed bracket members 42 and 43
through which we slidably pass another rod 50,
the upper end 50a ‘of which is outwardly angu

of the rod is pivotally attached to an outwardly
angularly bent and forked portion 60 of the rigid
member 29 by means of the pivot 55. Any‘suit
able handle may be provided at the lower end
thereof pivotally mounted on said ?rst arm and
the opposite end passing freely through an open-

member, adjacent the free end thereof, an ex
lever 51 pivoted at one end to the rod 40 by the
tending bracket portion on said support, a sub;
‘pivot 58. The lever 51 is provided with a slotted
stantially vertically disposed rigid member piv-_
opening 59 and the rod 50 is attached to the lever
51 by means of a pivot 6| operating in the slot 59.
It is thus seen from the above description that
when it is desired to close the jaws l4 and I5 it
is’ merely necessary to grasp the lever 51 and turn

bracket and having an opening adjacent the upper
free end thereof through which said horizontal
