Improved Bath with Circular Flow of Water for Washing
Photographic Pictures.
I, WILLIAM ROOKE, of 290 Caledonian Road, Middlesex, Draper, do hereby declare
the nature of this invention to be as follows.
The object of this invention is a novel construction of bath, in which Photo-
graphic pictures can be washed by a travelling or moving flow of water, said apparatus
having a siphonic draw off.
For the purpose of my invention, I construct a circular plan or trough and supply
water at an angle at the top for a circular flow.
The side of the pan has a well, in which is a turned up end of a pipe, this being
in connection with
in connection with a syphon. The bottom of the syphon pipe
perforated screens provided at the lower periphery, so that the draw off by the syphon
is in excess of the inflow.
The short pipe in the well is for breaking the inflow when the water has reached the
level, the pan then filling up again for a fresh syphoning.

page_text: I-WILLIAM-ROOKE, of 290, Caledonian Road, Middlesex, Draper, do hereby
declare the nature of this invention and in what-manner_the same is to be
performed to be particularly described and ascertained in and by the following
statement:
The object of this invention is a novel construction of bath in which Photographic
pictures can be washed by a travelling or moving flow of water, said apparatus having
a siphonic draw off.
For the purpose of my invention, I construct a circular or other shaped pan or
trough and supply water at an angle at the top for a circular flow. The side of the
pan bas a well in which is a turned up end of a pipe, this being in connection with a
siphon. The bottom of the siphon pipe is in connection with perforated screens
provided at the lower periphery, so that the draw off by the siphon is in excess of
the inflow.
The short pipe in the well is for breaking the siphon when the water has reached
the level, the pan then filling up again for a fresh siphoning.
The invention will be understood by the annexed drawings.
Figure 1 is a top perspective.
Figure 2 a perspective view looking from the bottom.
Figure 3 a sectional elovation through the lines a, b, of Figure 1.
Figure 4 a sectional elevation transversely to that shown at Figure 3 of a circular
bath in which photographic prints or plates can be washed.
Figure 5 is a perspective top view and Figure 6 a perspective bottom view of a
rectangular shaped trough or bath in which photographic negatives can be washed
when inserted into the frame shown at Figure 7.
All the letters refer to like parts in the several Figures.
A is the bath supplied with water from the spout B, or by the perforated cross bar O
in which the perforations are on opposite sides from the supply B for the jets of
water issuing from the perforations to swill round in a similar manner to the water that
would flow from the angled outlet pipe B.
D), D, are branches leading from the sides to a central well E under the bottom
plate F which may be flat or conical, the water passing from the bath A through
perforations indicated at Figure 3.
The well E has a branch & connected to it and this rises up on the outside of the
bath as at H with a turn over end I forming a siphon which acts when the bath A
becomes full. This siphon is of larger bore than that of the supply pipe B, consequently
when the siphonic action takes place the water flows out of the bath at a quicker rate
than that at which it enters.
J is an open top screen upon the outside of the bath and in communication with
the interior by perforations K, said screon J being also in connection with the siphon

page_text: leg H by a connecting pipe L, so that when the water becomes reduced in the
bath to the level of the pipe L the siphonic flow becomes broken, so that the bath
refills up with fresh water until it reaches the bend of the siphon for again
emptying the bath down to the level of the connection L, the action being automatic
and the bath never overflows.
Any kind of frame may be put in the bath A, if one be required, and as an
example of a frame for holding plates for immersion I show one at Figure 7
composed of two end frames M, M, connected by notched cross pieces N for
keeping the plates apart and for allowing the water full play between them for
washing purposes.
The angled inlet pipe B may have a rose on the end of it for the inflowing
water to be broken up into jets, or the jets may be from side pipe or pipes, as
at Figure 5, and instead of ono stream or one series of jets of water being
permitted to pass into the bath several sets of jets or supplios may be arranged.
The main feature is to cause a swilling action of the water upon, or against, or
between the photographic prints or negatives under operation and said photographic
pictures or negatives can be placed in and removed without interfering with the inflow
and outflow of water.
P, P, are legs to enable the bath to stand upon a table or bench.
The supply pipe B may be furnished with a regulating cock, or if a flexible tubing,
such as Q, be affixed it may lead a supply from an ordinary water cistern, or any
draw off tap of one.
If the pipe B be set at an angle from one end from the rectangular bath shown
at Figures 5 and 6, the water would have an oval direction of flow or a flow somewhat
approaching a circular would happen if the bath A be of square form should the
supply pipe be set at an angle.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The construction and arrangement of a bath for washing Photographic pictures'
in which bath an automatic siphonage is established for partially emptying
said bath and for automatically breaking the siphonic action for a refilling of the
bath as described and substantially as shown by the annexed drawings.
2. The improved bath shown on the annexed drawings, in which a circular or
equivalent swilling or moving body of water can be maintained for washing photo-
graphic pictures, said bath being furnished with means for automatic siphonage for
partially emptying, and means for automatically breaking the siphonage for the
refilling, all as set forth.
