Improvements in Apparatus for Producing and Discharging Currents
for Washing Photographic Plates and Prints or other Analogous
Purposes, Capable of being Attached for Use upon or to any
Ordinary Vessel.
I WILLIAM TYLAR, of 57 High Street, Aston, Birmingham, Dealer in Microscopic
& photographic apparatus, do hereby declare the nature of this invention to be as
follows:-
This invention relates to apparatus used for washing photographic plates and prints,
or other similar purposes, and the object of my improvements is the construction and
arrangement of such apparatus to agitate and cause the water to flow in several
differently directed currents, so as to thoroughly wash the said plates or prints &c.,
and also for the discharge of the overflow or impregnated liquid, by means of a pipe
which is made to act automatic, or otherwise, at the will of the operator; and further,
so constructed and arranged that it may be readily attached to, or carried upon, any
ordinary tank or vessel.
I provide what may be generally termed an inverted U shaped hollow box, or
syphon like pipe, which permits of its being readily hung or carried upon the side of,
say a bucket, or other vessel, that part of the said pipe overhanging the outside of
the bucket &c., being the discharge part or pipe.
At the upper end of the discharge pipe, the box is divided off into two separate
compartiments; the compartment of the discharge pipe continuing on again further,
downwards to the other end of the box, lying within the vessel; which said end may
be open, or covered with a perforated plate; or, such other perforations as may be
desired, may be made in such pipe near the end; thus there is a continuous but
independent passage from the one end in the vessel to the other end outside the
vessel forming a syphon.
Again, at the crown or upper part of the box, an opening is formed into the second
division or compartment, which said opening is provided upon its exterior, with a
nozzle or its equivalent, whereby it may be connected to a water main or other

page_text: supply. Thus this supply would enter and pass with more or less pressure. This
second compartment is then continued on as far as the inner end, or thereabouts, of
the syphon pipe, and its end closed or blocked up; or if preferred, it may be
formed of a separate pipe, connected to the syphon pipe at its crown or upper hent
part.
Near the lower end of this second pipe which will term the current producer,
and in its interior, I provide short angular outlet pipes or tubes: three of such ontlet
tubes I find to answer well, but I may add more or put loss. Those said tubes aro
placed at various desired angles to each other, so that as the water &c. passes through
them into the vessel, it shall issue therefrom in differently directed streams, thereby
producing considerable agitation or whirling in the water in the vessel, in order to
horoughly wash the plates or prints &c. placed therein. Upon the exterior of the
current producing pipe, and in suitable proximity to the outlet openings of the
angular tubes. baffle plates may be used, so as to still further direct the issuing
streams.
Again, at the upper part or crown of the syphon pipe, a communication is mate
from the supply chamber thereinto, so that when such communication is open, tho
water may
also pass down the outer portion of the said syphon pipe; provision
however, is made so that at will such communication may be cut off, by means of a
valve or its equivalent, operated from the exterior. Thus when the apparatus as
already described is in action, and the valve open, the passing of the water down the
discharge pipe, exhausts the air from the whole of its length, and consequently pro-
duces the syphon action; when the valve may be closed, and the syphon nction would
automatically continue, discharging the surplus water &c. from the vessel or tank.
By these arrangements an apparatus is made, which is simple, effectual, and con-
venien, as it may be applied to any ordinary vessel or tank.

I WILLIAM TYLAR of 57 High Street, Aston Birmingham Dealer in Microscopic
and Photographic apparatus 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 apparatus used for washing photographic plates and prints
or other similar purposes, and the object of my improvements is the construction and
arrangement of such apparatus to agitate and cause the water to flow in several
differently directed currents, so as to thoroughly wash the said plates or prints &c.,
and also for the discharge of the overflow or impregnated liquid, by means of a pipe
which is made to act automatic, or otherwise, at the will of the operator; and further,
so constructed and arranged that it may be readily attached to or carried upon any
ordinary tank or vessel.
1 provide what may be generally termed an inverted Ushaped hollow box, or
syphon like pipe, which permits of its being readily hung or carried upon the side of,
say a bucket, or other vessel, that part of the said pipe overhanging the outside of the
bucket &c. being the discharge pipe.
At the upper end of the discharge pipe, the box is divided off into two separate
compartiments; the compartment of the discharge pipe, continuing on again further
downwards to the other end of the box lying within the vessel, which said end may
be open, or covered with a perforated plate, or such other perforations as may be
desired, may be made in such pipe near the end; thus there is a continuous passage
from the one end in the vessel, to the other end outside the vessel forming a
syphon.
Again, at the crown or upper part of the box, an inlet or opening is formed into
the second division or compartment, which said opening is provided upon its exterior
with a nozzle or its equivalent, whereby it may be connected to a water main or other
supply. Thus this supply would enter and pass with more or less pressure. This
second compartiment is then continued on as far as the inner end or thereabouts of the
syphon pipe, and its end closed or blocked up, or, if preferred, it may be formed of a
separate pipe connected to the syphon pipe at its crown or upper bend part.
Near the lower end of this second pipe, or compartment, which I will term the
current producer, and in its interior, I provide short angular outlet pipes or tubes,
three of such outlet tubes I find to answer well, but I may add more or put less.
These said tubes are placed at various desired angles to each other, so that as the
water &c., passes through them into the vessel, it shall issue therefrom in differently
directed streams, thereby producing considerable agitating or whirling of the water
in the vessel, in order to thoroughly wash the plates or prints &c. placed therein.
Upon the exterior of the current producing pipe and in suitable proximity to the
outlet openings of the angular tubes, baffle plates may be used, so as to still further
direct the issuing streams.

page_text: supply chamber thereinto as shown by the arrow m, so that when such communication
is open, the water may not only pass down the current producing pipe, but may also
pass down the outer or discharging portion 6, of the syphon pipe.
n, is a chamber covering and embracing the openings o, & p, by which the afore-
said communication between the supply chamber c, and the syphon chamber d, is
made, and also provided with screw pin q.
A valve r, is carried upon a metallic springs, the tendency of which is always to
open the said passage p, but which may be closed down, by means of the scrow
pin q.
Upon the front of the apparatus I may in some cases provide a metal slide æ, for
the purpose of partly or entirely covering one or more of the angular outlets j.
Thus having placed the apparatus upon the side of the tank as shown, and connected
the nozzle h, to the water supply, its action would be somewhat thus:-The water
passes down the pipe c, and out through the angular pipes j,j,j. Having now filled
or nearly filled the tank, the valve r, is opened, when the water also rushes there-
through into the compartment d, and down the discharge pipe, and in its rush carries or
drives the air in the upper part of the chamber d, with it, and thus creates a vacuum,
when the water from the end e, will follow, the syphon action being now complete,
when the valve r, may be closed.
Or, if preferred, the apparatus may be started by unscrewing the top screw 9,
and then turning the regulator t, so that it blocks the discharge pipe (as seen in
Fig. 4).
This allows some of the water from the tap to flow into the syphon tube d, which
becomes gradually filled, the pent up air therein, oscaping through the angular
tubes,,, rising in the form of air bubbles, to the surface of the water, in the tank.
Such air bubbles having ceased, the regulator is turned round to allow the water to
pass out (as seen in Fig. 5), when the amount of water supplied, can be readily
regulated so that the apparatus will continue to discharge the tank at the same rate as
it is supplied.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1st. The improvements in apparatus for producing and discharging currents, for
washing photographic plates and prints, or other analogous purposes, that is to say,
the combination and use of the internal angular outlet tubes j, within the supply pipe,
substantially as described and illustrated upon the drawings, and for the purposes
specified.
2nd. The combination in a washing or current producing apparatus for photo-
graphic purposes, of the valve, with the outlet or discharge pipe b, constructed and
operating substantially as hereindescribed and illustrated, and for the purposes
specified.
3rd. The general combination and arrangement of parts constituting this my
improved washing apparatus for photographic or other analogous purposes, sub-
stantially as hereindescribed and illustrated upon the drawings.
Dated this 25th day of March 1889.
