SECURING AND SEALING vIWEAN S FOR
METER BOX HOUSINGS
John A. Obermaier, River Forest, Iii.
Application January 6, 1944, Serial No. 517,256
1 Claim. (Cl. 220—--18)
1
This invention relates to securing and sealing
means and has to do with means for securing
a structure on a base and for effecting a sub
stantially ?uid tight seal between the structure
and the base.
It is frequently desirable to provide a ?uid
tight seal between a base member and a struc
ture mounted thereon such as, for example, a
meter housing mounted on a base. It is-known
to mount meter housings and analogous struc
tures on bases by means of posts secured to a
base member and receiving securing screws which
2
ing means whereby a meter housing or other
structure may be secured upon a base'member
with expedition and facility so as to assure a
?uid tight seal between said members, while
avoiding the above referred to objections to the
known structures brie?y described above. More
speci?cally, I provide a base member and means
for securing thereon a housing or wall structure
with a sealing gasket interposed between the
housing or wall structure and the base member,
the securing means comprising means for forcing
the housing or wall structure toward the ‘base '
member and thereby compressing the sealing
pass through the outeror front wall of the hous
gasket. vThe securing means, in the more spe
ing, there being a sealing gasket interposed be

tween .the housing and the base member. In
