14 Claims.
This invention relates to dispensers for ñuids;
such, for example, as are used in and about serv
ice stations for automotive vehicles. As shown
and herein described, it is used primarily for dis
CTl pensing water and air. It is to be understood,
however, that it is adaptable for dispensing other`
fluids and for use in places other than service
stations.
on or about March 4, 1935, 1 med application'
, l0 N0. 9,189 for a patent covering an apparatus for
the same general purpose.
Subsequently, I made
some changes in that >apparatus which changes
are embodied in the present invention. As re
spects the subject matter that is common to these
l5 applications, the present case may be considered
a continuation in part of the said earlier appli
cation, although the latter has now become aban-,
doned.
