DEVICE
FOR
WASHING PHOTOGRAPHIC
PRINTS
Frederick C. Schnelz, Detroit, Mich.
Application April 9, 1937, Serial No. 135,863
4 Claims.
rl‘he present invention relates to washing or
spray devices generally, and in particular provides an improved device for washing photographic prints or the like.
5
A relatively wide variety of devices have heretofore been proposed for the purpose of washing
photographic negatives or prints, following the
treatment thereof with developing solutions.
Conventionally, the washing operations are ef~
10 fected in trays or pans, and the devices in question may take the form of nozzles or sprays which
are designed to cause a circulation of the water
over and past the negatives or prints in order
to remove all traces of the developing solution
15 therefrom. An illustrative arrangement of this
kind is shown in the Nichols Patent No. ‘1,136,705,
granted April 20, 1915.
.-
Devices of the Nichols type, however, as well
as others, of which the present applicant is
20 aware, are objectionable either in that they do
not effectively maintain the water in circulation
relative to the negative or prints, in that they
permit the-negatives or prints to become stuck
together, or in that they cannotreadily be ad25 ‘justed to modify the circulating effect or to adapt
(01. 95-97)
corresponding reference characters are used to
designate corresponding parts and in which:
Figure 1 is a View in front elevation of a typical
photographic washing arrangement;
Fig. 2 is a view in vertical section of the im- 5
proved washing device; and
‘ Fig. 3 is a plan view, taken along the line 3—3
of Fig. 2.
Referring ?rst to Fig. 1, it will be appreciated
that photographic or similar washing operations 10
are conventionally effected by depositing the
negatives 01' prints, 01“ ether Specimens, as the
case may be, within a tray or pan II), which in
turn is deposited within a collecting device such
as the sink I2. The washing solution, conven- 15
tionally water, is supplied to the tray Ill through
a hose l4, and a nozzle structure I6, to the con
struction and arrangement of which the present
invention is primarily directed. The Water is
circulated within the tray 01" pan to by the nozzle I20
structure I6, and over?ows from the tray Ill into
the sink I2.
>
Referring more particularly to Figs. 2 and 3,
the device It Comprises a nozzle member I8
which is remcvably and adjustably secured to the
them to differing constructions of washing'trays
side wall of the Dan 01' tray to by means of the
or pans. The present invention is directed pri-
clamp 20. The nozzle member I8 is illustrated
marily to the provision of a washing device which
completely overcomes all of the just noted ob30 jections, as well as others,
With the foregoing considerations in view,
objects of the present‘invention are to provide
a device of the above indicated character, adapted to both maintain a washing solution in circulation and keep prints or negatives or the like
separated from each other; to provide such a device which is readily adjustable to modify the
circulating and separating effects; to provide
such a device which is readily adjustable to dif40 ferent depths of washing trays or pans; to pro~
vide such a device which may be readily secured
to and separated from washing trays or pans of
different sizes and constructions; to provide such
a device embodying a clamping member adapted
45 to be secured to a washing tray or pan, and. embodying a spray or nozzle member having one or
more rows of ori?ces through which angularly
displaced streams of water may be directed to
cause a circulation within the tray or pan and
50 also to cause the prints or negatives to remain
separated from each other.
With the above, as well as other objects, in
view, a preferred but illustrative embodiment of
the invention is shown in the accompanying
55 drawing, throughout the several views of which

as being of tubular form, One end of Which is
received within the end of the hose I4, and the
lower end of which is closed, as by a suitable 30
plug (not shown). I Preferably and as illustrated,
at least two separate rows of ori?ces I811 and
I 8b are provided in the Side Wall Of the tube
I8, the two rows being in aneularly spaced rela
tion to each other. With this arrangement, and 35
by rotating‘ the HOZZIe '8 t0 the position Shown
in Fig- 3, a plurality of Streams of Water may be
caused to issue from the ori?ces I8a in a direc
tion generally parallel to the side Wall I 0a of
the tray 01“ Dan 10. These Streams of Water 40
effect a circulation of the water around the pan,
causing it to ?ow continuously and without sub
stantial turbulence Over any negatives or prints
or other specimens which may be disposed within
the pen- At the Same time, a Corresponding 45
series of streams of Water may be caused to
issue from the ori?ces 58b in a direction gener
ally transverse of the wall Iiia, which streams
of water impinge upon the edges of the prints
or negatives and tend to flow between the suc- 50
cessive layers of the prints or negatives. This
action is found in practice to e?ectively keep the
prints Or negatives freely separated, thus insur
ing that the entire surface of each print or
negative is completely Washed by the water.

of the surface of the walls lOa, so that a tilting
or rocking of the clamp is prevented, and the
outer leg 22 is provided with a threaded opening
26, to receive a locking stud 28.
The inner end

Illa, and may be turned between the locking and

In order to accommodate the nozzle I8, the
bracket 20 is provided adjacent its upper edge
with a boss 32, which is bored to freely, slidably

and rotatably receive the nozzle I8.
A locking
stud 34 is received within the threaded open

inwardly or outwardly by the knurled head 36 to
into a tray or like container and having one or
more ori?ces in the side wall thereof through

bracket having a U-shaped portion adapted to fit
over the side of said container, and means for
locking said bracket to said container and for
locking said nozzle within said bracket.

It will be appreciated that the complete device
a nozzle member provided with a plurality of

It will also be appreciated that it may be readily
and quickly applied to and removed from trays or
pans of widely varying constructions, and that,
in the clamped position on a tray or pan, it is
rigidly held against tilting or rocking. It will
also be appreciated that the provision of the ad
justment between the nozzle 18 and the bracket 20
permits the nozzle [8 to be adjusted both verti
cally, to accommodate it to pans or trays of
40 differing depth, and also permits it to be rotative
' 1y adjusted to selectively control the direction of
?ow of the sprays or streams of water from the
several rows of ori?ces.
Although a speci?c embodiment of the inven

plication or use therefor, it will be appreciated
that the invention may be applied to uses other
than those speci?ed, and may be embodied in
forms differing widely from the illustrated form.

What I claim is:
1. In a device of the character described, for
use with a tray or like container adapted to re
ori?ces therein adapted to eject streams of liquid
therefrom in the same general plane, said nozzle 30
member being axially adjustable relative to said
bracket whereby to permit its vertical relation
with respect to the bottom of said container to
be varied, and means for releasably and rigidly
securing said nozzle member in axially adjusted 35
relation with respect to said bracket.
4. A device for use in the washing of photo
graphic prints comprising, in combination, a
bracket adapted to engage over the side of a
container, means for releasably and rigidly se
curing said bracket to the side of said container,
a nozzle member provided with a plurality of ori
?ces therein adapted to eject streams of liquid
therefrom in the same general plane, said nozzle
member being rotatably adjustable relative to _
said bracket whereby to permit the angular rela
tion of said streams with respect to said container
to be varied, and means for releasably and rigidly
securing said nozzle member in rotatably adjusted
relation with respect to said bracket.
