page_text: 1, WILLIAM KERR, of High Street, Lochwinnoch, Renfrewshire, Engineer, do
hereby declare the nature of this invention to be as follows:-
"This invention relates to a new and improved device for washing photographic
prints.
The device consists of a cylinder free to turn on its axis, which may be either
horizontal or vertical, in a trough of water. The cylinder has longitudinal slots
cut in it at intervals and the prints are held, one at the edge of each slot, by means
of spring catches or the like. At or near the edge of each slot is fitted, preferably
on the inside of the cylinder, a vane or bucket in or against which one or more jets
of water, from a perforated or slotted tube or pipe fitted within the cylinder and
supplied with water from any convenient source, is directed so as to cause the
cylinder to revolve with a turbine or water wheel action. As the cylinder
revolves the water escapes from it out between the prints and effectually washes
them.
The water escapes from the trough either by an overflow or through a suitable
stop cock..

I, WILLIAM KERR, of High Street, Lochwinnoch, Renfrewshire, Engineer, 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:-
This invention relates to a new or improved device for washing photographic
prints.
And in order that my said invention may be properly understood I have
hereunto appended an explanatory sheet of drawings, whereon,
Fig. 1 is an end elevation of the device.
Fig. 2 is a section on the line x-x of Fig. 1. .
Fig. 3 is a plau.
Fig. 4 is a half section of the revolving cylinder on the line y-y Fig. 1. The
supply pipe is shown as sectioned through 2-2 Fig. 1.
Referring to the drawings:-
The device consists of a cylinder a which is free to turn on its axle b in a trough
of water c. The line c¹ Fig. 1 shows the water level. The cylinder a has
longitudinal slots d cut in it at intervals and the prints (indicated in dotted lines
D

page_text: at e) are held in place, one at the edge of each slot, by means of spring catches f
or such like. At or near the edge of each slot is fitted, preferably on the inside of
the cylinder, a vane g or bucket, on or against which one or more jets of water,
from a perforated or slotted pipe h, fitted within the cylinder and supplied with
water from any convenient source, is directed so as to cause the cylinder to
revolve.
i are bearings for the axle b.
When water is admitted to the pipe it issues from the small holes h¹, and,
striking against the vanes g, causes the cylinder to revolve with the prints secured
to it. The water escaping from the vanes through the slots d passes between the
prints and thoroughly washes them.
jis an overflow pipe.
Ae will be seen a cone k is preferably fitted to the axle b as a stay.
The cylinder may be arranged. vertically in the trough and be revolved with a
turbine action.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I consider novel and desire to claim is :-
A device for washing photographic prints constructed and operating substantially
as herein before described with reference to the drawings annexed.
