Referring more in particular to the form of the inven
tion shown in the drawings. the face bath illustrated in
FIGURE 1 comp-rises a basin 10 rigidly mounted on the
face of a wall or other suitable support. This basin. for
the purposes of illustration is elliptical in shape, as shown
in FIGURE 5, but may be made in any convenient form.
The form illustrated has the side aprons 11, 11 (shown
in FIGURE 7) on ‘each side thereof, and these aprons
are made in one continuous piece with the top surface
of the face bath, so as to form a water retaining bowl
portion 12, shown in FIGURE 1. This basin for con
venience and appearance may be made of enameled iron,
vitreous china or stainless steel.
The bowl or Water retaining portion 12 of this basin
is connected to a drain 13 by means of a conduit 14,
having the usual trap 15 therein. Arranged on each side
of the basin are spray nozzles 16 ‘and 17, as shown in
FIGURE 2, discharging towards one another from each
ticularly corrosive chemicals that are accidentally intro
duced into the eyes and on the face.
These baths have a 25
spray head with small openings therein directly attached
to a source of water under pressure, so as to discharge a
solid stream of liquid in an arc intersecting mid-way the
length of the bowl, so as to subject the eyes and face to :1
solid stream of Water without any ‘air therein. The prob 30
lem of equal liquid distribution was solved in the Benson
Patent 2,482,960, by having a common manifold. In the
Logan Patent 2,775,774 a solid stream of water is dis
charged in the same manner to produce the same results
as it was in the Benson patent, and the problem of liquid 35
distribution was solved by means of a baffle within the
spray piece. Both of these patents recognized the prob
lem of obtaining equal liquid distribution on each side of
the face washing device. Both also disclosed the use of a 40
solid stream of water, or a multiplicity of small solid
streams of water.
It is an object of this invention to provide an eye bath
having a water spray arranged in coniunction with a
pressure regulator.

In operation, a person approaches the eye bath and
opens the quick acting valve 27 admitting water from the ‘
main 29’, which ?ows through the conduit 26 into the
regulator and equalizer 23. It then ?ows through the
condiuts ‘21 and 22 and through the nozzles associated
therewith to form a curtain of. Water in the basin 10.

The flow control device disclosed herein is of the
type shown in the application, resulting in Patent 2,914,
048, issued November 24. 1959. This device automatical
ly regulates the volume of water with variations in pres

screen 96 inserted from the end thereof and held in place
by the screw cap 97. The same screen assembly is in the
cold water conduit.
It has been found that a 2 g.p.m. ?ow control device in

Another illustration of the method of initiating the
flow of water is shown in FIGURE 8, wherein the basin
50 has the aerator nozzles 51, 51 arranged on each side
of the interior thereof. The water supply pipe 52 is con
nected to the conduit 53 which is connected through the
104° F., and the volume will remain constant regardless
of the pressure in the water supply line. Temperatures
within this range are readily tolerated by the face and
eyes and therefore for the ?rst time it has been possible
to construct an eye wash device with a single valve oper~

control the temperature and at the same time control the
