Hot water.
I, WILLIAM DUNDAS SOOTT MONORIEFF of the North British Plumbing Company,
86 Newman Street, London in the county of Middlesex, Engineer, do hereby declare
the nature of this invention to be as follows :-
The object of this invention is to provide an apparatus for automatically discharging
any required volume of hot water at such periods of time as may be desired.
The invention is particularly applicable to the flushing of sink pipes, house drains
or conduits, wherein fatty or other objectionable matter is apt to lodge.
The invention consists in the novel combination and arrangement of parts as
follows:-
:-
I employ a tank having an ordinary discharging syphon preferably of the annular
type, and hot water supply pipe and cock controlled by a counterweighted lover
suitably centred and having on its end within the tank a suspended receiver provided
with a syphon, the longer leg of which is carried down towards the bottom of the
tank for a suitable distance.
This suspended receiver is fed by a supply pipe controlled by a tap adjustable to
any desired rate of flow. When the weight of the contents of the suspended receiver
exceeds that of the counterweight the lever descends and opens the hot water valve,
so filling the tank up to the point at which its syphon discharges; the descending
column of hot water causing partial vacuum in the syphon of the suspended receiver
empties it, and by the action of the counter weight the hot water valve is closed and
so remains until the drip from the adjustable tap again fills the suspended receiver
when the above described action is automatically repeated.
It will be obvious that the volume of discharge depends on the dimensions of the
tank, and the periods of discharge on the rate of the supply to the suspended receiver
and the position of the counterweight.

page_text: A New or Improved Apparatus for Automatically Discharging
Hot Water.
I WILLIAM DUNDAS SCOTT-MONCRIEFF of the North British Plumbing Company
86 Newman Street, London, in the county of Middlesex 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 :-
The object of this invention is to provide an apparatus for automatically discharging
hot water at such periods of time as may be desired.
The invention is particularly applicable to the flushing of sink pipes, house drains,
or conduits wherein fatty or other objectionable matter is apt to lodge.
The invention consists in the novel combination and, arrangement of parts as
follows:-
I employ a tank having an ordinary discharging sypon preferably of the annular
type, and hot water supply pipe and cock controlled by a counterweighted lover
suitably centered and having on its end within the tank a suspended receiver provided
with a syphon, the longer leg of which is carried down towards the bottom of the
tank for a suitable distance.
A sectional view of this arrangement is shown in Figure 1 of the accompanying
drawing in which a is the tank, the syphon shown as of the ordinary type and
having its shorter leg extended as near the bottom of the tank as it is desired to
empty the same, is the hot water supply pipe fitted with an ordinary push valve c¹
d is the lever centered conveniently within the tank with counterweight d projection d
or other suitable equivalent means of operating the valve c', e. is the suspended
receiver with its syphon e' whose longer log is extended as near the bottom of the
tank as may be to allow of the necessary movement of the lever d, and is the supply
pipe with regulating cock f¹. The periods of discharge depend upon the rate of
supply to the receiver e by pipe f, and the position of the counterweight d¹ on
lever d.
When therefore these have been adjusted as required the suspended receiver e
gradually fills until the weight of it and its contents exceed that of lever and
weight d. d. The receiver then descends and the projection d² on lever d con-
sequently opens automatically the hot water valve c¹; the tank a then fills up to the
point at which syphon & discharges. The descending column of hot water in the
tank causing partial vacuum in the syplion el empties the receiver e and by the action
of the counterweight d¹ the receivor is raised and the valve c' closed, and so remains
until the drip from the adjustable tap f¹ again fills the suspended receiver when the
above described action is automatically repeated. The same principle may be effected
by the modified arrangement shown in section in Figure 2, wherein similar letters are
used to indicate similar parts,
U

page_text: In this case the suspended receiver e and its syphon e¹ are dispensed with, and a
fixed receiver e substituted therefor and situated at the bottom of the tank, and the
foot of the discharging syphon bis extended to near the bottom thereof as illustrated
in Figure 2; in this receiver e is situated a float or ball h attached to the free end of
a lever g centered in the tank as at g', the float lever g is connected by rod d³ with the
free end of the lever d which as before is arranged to act upon the valve c¹. The
drip from the supply pipe gradually filling the receiver e floats the ball which
through levers I. and d opens the valve e' allowing the tank to fill as before to the
point at which the syphon discharges, and the whole of the contents of the tank and
the receiver e are discharged by the syphon : then the float again falls and closes
the hot water supply valve c' which is again opened when the receiver becomes filled
and the cycle of operations is automatically repeated as before.
The arrows in the figures indicate the direction of flow.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I
claim is.
1. An apparatus for automatically discharging hot water consisting of a tank with
fixed discharge syphon, a hot water supply pipe with valve adapted to be automatically
operated by the movement of a counterbalanced lever consequent upon the periodic
filling of a receiver by a supply pipe with regulating valve substantially as set
forth.
2. The combination and arrangement of parts constituting respectively the two
modifications of improved apparatus for automatically discharging hot water sub-
stantially as described and illustrated by the accompanying drawing.
