page_text: I, ALEXANDER KELLAR, of Dumfries Engine Works, Bute Docks, Cardiff, in the
County of Glamorgan, Engineer, do hereby declare the nature of this invention to
be as follows:
My invention relates to the construction of an improved apparatus for washing
photographic prints, and consists in a perforated cylinder capable of rotation within
an outer vessel.
The cylinder has formed in it suitable openings at which the prints can be
introduced.
I form floats upon the periphery of the cylinder upon which a jet or jets of water
play causing the cylinder to revolve, and therefore carry the prints through the water
delivered into the outer vessel.
The latter is fitted with suitable openings for the escape of the water.
The dynamic force of the jets above mentioned may be replaced or supplemented
by any convenient type of mechanical motor.

page_text: COMPLETE SPECIFICATION.
Improvements in Apparatus for Washing Photographic Prints.
I, ALEXANDER KELLAR, of Dumfries Engine Works, Bute Docks, Cardiff, in the
County of Glamorgan, 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 :-
My invention relates to the construction of an improved apparatus for washing
photographic prints, and consists in mounting a perforated cylinder to contain the
prints within an outer vessel serving as a tank, within which it can be rotated by
means of a jet of water playing upon the floats of a water wheel combined with the
said perforated cylinder.
I attain the object of my invention by means of the mechanisms illustrated in the
following figures which are to be taken as part of this specification and read there-
with, and in which like parts are marked throughout the figures in which they occur
with the same reference letter.
Fig. 1 is a sectional longitudinal elevation through the axis of the apparatus.
Fig. 2 is a perspective view of an apparatus.
Fig. 3 is a longitudinal sectional elevation, to a larger scale than the preceding
figure, illustrating the connection of the perforated cylindrical axis of the washing
cylinder with the exhaust.
Fig. 4 is an end elevation to a still larger scale of the fixed bearing of the washing
cylinder within the exhaust.
Fig. 5 is a transverse sectional elevation taken on the line A B of Fig 1.
Fig. 6 is a part transverse sectional elevation taken on line CD of Fig. 1.
E is the water tank, of any suitable material and capacity, and is conveniently
provided with lifting handles e, feet e¹, and an overflow e².
F is the perforated washing cylinder with closed ends f. It may be made of any
suitable material, and of any suitable shape.
It is shewn as circular in cross section, but my invention is not confined to making
it of this shape. Access to its interior is provided for by an opening in its periphery
fitted with a sliding door f¹ fixed at any point thereon.
G is a water wheel fixed on one end of the cylinder. The water wheel may be
separate from the cylinder, and connected therewith by power gearing, of any suitable
type, if the pressure of the jet of water available for rotating the wheel is of too low
a pressure to drive the washing cylinder direct.
The water jet is delivered into the tank E, by a suitable pipe connection 9, at any
suitable height and at a proper angle with the floats of the wheel to exert the best
possible effect upon them. I may use more than one jet.
H is a perforated axial cylinder extending from one end of the washing cylinder to
the other, to prevent the exhaust being closed by the prints within the cylinder.
The washing cylinder is carried on two centre pins h, h¹. One of these, h, projects
through the end of the tank and is adjustable, as shewn, for the purpose of facilitating

page_text: the mounting or removal of the washing cylinder. Its bearing h³ is a central
enlargement of the adjacent end of the washing cylinder. The opposite bearing h³
is perforated, or surrounded by perforations, to allow of the water flowing away from
the tank by the exhaust.
The exhaust consists of three pieces of a circular cross section. One, a hollow
bearing i, springs centrally from the adjacent end of the washing cylinder, embracing
the perforated bearing above mentioned, and enters the next one j, which acts as a
bush, and is fixed to the adjacent end of the water tank with which it also makes a
water tight connection. Arms k project internally from the sides of the bush j, and
through their junction is passed the second centre pin . The third part of the
exhaust is an elbow of a suitable length. The object of providing this movable
extension of the bush is that the water level in the tank may be easily regulated by
adjusting the height of the nose above the bore of the bush j. It is evident that
the elbow may be replaced by such an equivalent as a short length of flexible tube.
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 claim is :-
1. The combination of water tank, perforated washing cylinder revolvable therein
by means of a jet of water admitted into the tank, and discharging upon a water
wheel combined with said washing cylinder, and an exhaust from said tank ;
substantially as described with reference to the accompanying figures.
2. The combination of water tank, perforated washing cylinder revolvable therein
by a jet of water discharged on to a water wheel combined with said washing
cylinder, a perforated central cylinder within said washing cylinder and commu-
nicating with the exhaust through a perforated bearing, substantially as described
with reference to the accompanying figures.
3. In a revolving apparatus for washing photographic prints, the combination of a
revolving perforated washing cylinder, a perforated axial cylinder extending from
one end of the washing cylinder to the other, and an exhaust consisting of a tube
embracing a perforated bearing and working watertight within a bush fixed in the
end of the water tank, a centre pin supported by said bush and engaging in said
perforated bearing, and an external tubular continuation of said tube and bush
adjustable for the purpose of regulating the level of the water in the tank, sub-
stantially as described with reference to the accompanying figures.
Dated this nu uay of August 1007.
