This invention relates generally to devices for
discharging or distributing ?uid pressure media,
and particularly to portable ?re extinguishers.
An object of the invention is to provide a com
bined handle and discharge means or horn unit
particularly
adapted
for
portable
?re
eX
tinguishers.
Another object is to provide a unit of the above
indicated character wherein positioning of the
T horn controls the discharge of ?uid pressure
media.
Another object is to provide a unit of the above
indicated character that is simple and‘durable
in construction, economical to manufacture and
effective in operation, and lends itself to more
ornate design without the sacri?ce of any element
of its function.
'
Other and further objects of the invention will
be obvious upon an understanding of the illus—
trative embodiment about to be described, or will
beindicated in the appended claims, and various
advantages not referred to herein will occur to

stem 46 extending through the outlet 36 into the
bore 42, and is normally held in closed position
against the seat 34 by the fluid pressure and by
a spring 48 backed by a screw plug 50 in the
threaded end portion 30 of the housing 24.
The operating means I4 comprises an elbow
conduit 52 having a portion 54 normally in hori
zontal position along one side of the housing 24,
and a portion 56 across the end portion 30 of the
10 housing. The inner or upstream end 58 of the
‘ conduit portion 54 is screw threaded into a mem
her 60 having a bore 62 communicating with the
conduit portion 54 and with the bore 42 and also
having a cam end 64 for cooperation with the
15 valve stem 46 to effect unseating thereof.
The unit l6, may .be molded or otherwise
formed of metal, plastic material or the like, as
a single integral piece, or in ‘longitudinally di
vided complementary halves or other form. The
20 discharge means or horn l8 and the handle 20
of the unit are shaped somewhat on the order of
a pistol grip and barrel respectively, with a
invention in practice.
A preferred embodiment of the invention has
portion 66 in position corresponding generally to
the trigger position of a pistol. At the latter
position, where the unit I6 is of plastic material,

In operation, the assembly is carried, as afore
said, from its waiting position to the location of
a ?re and, when ready, the operator, without
using his other hand, or the ?ngers of his
carrying hand other than for carrying, and with
one simple ?ip motion causes the unit IE to move
from the full line position to the broken line

During this motion, when the horn l8 has
passed through about 45° of its ninety degree
