While I have illustrated and described what
I now regardas the preferred embodiment of my
invention, the construction is, of course, subject
with a trunnion, said body having a slot for re
to modi?cations without departing from the spirit
and scope of my invention. I, therefore, do not
wish to restrict myself to the particular form of
ceiving the upper end of said ?xed member, and
said slot provided with grooves terminating at
the bottoms thereof in bearing surfaces for the
ends of said trunnions, a plate secured to said
body and engaging the ends of said trunnion at
the surface thereof to hold the bearing surfaces
of said body engaged with the bottom of said
trunnion thereby pivotally to connect said body
to said ?xedmember, and said ?xed member pro
