Improvements in Photographic Print Washers.

page_text: Improvements in Photographic Print Washers.
I, GEORGE TOM HARRISON, of Town Street, Horsforth, near Leeds, in the
County of York, Metal-plate Goods Manufacturer, do hereby declare the nature
of this invention to be as follows:-
The object of my invention is to construct an improved photographic print
and plate washer, with a perfect and uniform action, and so arranged as to
prevent choking of the outlet or damage to the prints or plates.
I employ an ordinary metal body or barrel, which I mount on a suitable
stand.
The water inlet consists of a series of holes or perforations, which extend
along the bottom of the barrel from end to end, and are inclined so as to give
a rotary movement to the water.
The outlet consists of a parallel series of holes or perforations, which are
preferably slightly larger than the inlet holes.
The two series of holes run closely parallel, so that the water issuing from
the inlet holes tends to keep the outlet holes clear. By this means the outlet
holes cannot become choked by the prints as they are carried round.
Separate inlet and outlet conduits, in connection with the holes or perforations,
run longitudinally beneath the barrel, the inlet pipe being preferably carried from
the top, and the outlet being syphoned over so as to discharge at the bottom and
so prevent splashing.
The inside of the washer forms an unbroken curved surface and has no pro-
jecting parts. The prints and plates are therfore not liable to damage during the
washing.

I, GEORGE TOM HARRISON, of Town Street, Horsforth, near Leeds, in the
County of York, Metal Plate Goods Manufacturer, do hereby declare the nature
of this invention, and in what manner the same is to be performed, to be parti-
cularly described and ascertained in and by the following statement:-
The object of my invention is to construct an improved photographic print

page_text: and plate washer, with a perfect and uniform action, and so arranged as to
prevent choking of the outlet or damage to the prints or plates.
DESCRIPTION OF DRAWINGS.
Fig. 1 shows a cross-section of my improved washer.
Fig. 2 is a plan of Fig. 1.
Fig. 3 shows a cross-section of washer slightly modified.
Fig. 4 is a plan of Fig. 3.
In the figures like parts are indicated by like reference letters.
In constructing the apparatus I employ an ordinary metal body or barrel A,
which I mount on a suitable stand B. The feed water inlet consists (see Figs. 1
and 2) of a series of holes or perforations C, which extend along the bottom of
the barrel A. from end to end and are inclined so as to produce a rotary move-
ment of the water within the barrel.
The waste water outlet consists of a parallel series of holes or perforations D,
which are preferably slightly larger than the inlet holes C. The two series of
holes run closely parallel, the inlet holes C and the outlet holes D being
preferably arranged at alternate intervals (see Fig. 2), so that the rush of water
from each inlet hele passes between the adjacent pair of outlet holes, so dis-
lodging any print having a tendency to settle over the outlet holes D. By this
means the outlet holes D cannot become choked by the prints as they are
carried round the washer.
Separate inlet and outlet conduits E and F, in connection with the inlet holes C
and outlet holes D, run longitudinally beneath the barrel A, the inlet pipe G
being preferably carried from the top of the washer, and the outlet being
syphoned over at H so as to discharge at the bottom and so prevent splashing.
In place of the inlet holes C a fan feeder K (see Figs. 3 and 4) with a semi-
circular opening to the inside of the barrel A may be employed. In this case
the pipe G and inlet conduit E are dispensed with.
As the interior of the washer forms an unbroken curved surface with no
projecting parts, the prints or plates are therefore not liable to damage during
the washing operation.
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. In photographic print and plate washers of the barrel type, the employment
of a series of inclined inlet holes and an adjacent and parallel series of outlet
holes, so as to produce a uniform rotary action without liability to choking of
the outlet, substantially as shown and described.
2. The photographic print and plate washer consisting of the barrel A, stand B,
inlet pipe G, inlet conduit E, inclined inlet holes C, outlet holes D, outlet
conduit F, and outlet syphon H, all arranged substantially as, and for the
purposes, shown and described.
3. The photographic print and plate washer consisting of the barrel A, stand B,
inlet feeder K, outlet holes D), outlet conduit F, and outlet syphon H, all arranged
substantially as, and for the purposes, shown and described."
