An Improvement in Hot Water Circulation Apparatus.
I ALICE MARY BUSHELL, of 39 The Broadway, Stratford, London, E. do
hereby declare the nature of this invention to be as follows:—
My invention relates to an improvement in water heating and circulating
apparatus for domestic purposes of that kind in which the ordinary high pressure
boiler heated by a special flue as now arranged in kitcheners and self-setting
ranges is replaced by a coil of piping placed wholly within the fire space itself,
and therefore in direct contact with the fire.
The coil in question may either be of zigzag form disposed so as to extend
across the back and two sides of the fire space or it may be a continuous square
or oval coil or be otherwise arranged so as to expose the requisite extent of
heating surface to the fire.
The object of the present invention is to ensure the removal of all sediment
from the water and so prevent any solid matters being carried by the ascending
current of water into the flow circulation pipe or where it would be liable to deposit
in bends or otherwise, and obstruct the free circulation of the water.
This object is attained by the direct impact of the water at the point where
the circulation is most vigorous against a vertical surface which is substantially
at right angles to the flow of the water as it leaves the heating coil so that the
course of the water being abruptly changed from the horizontal to the upward
direction the solid matters in suspension will be caused to settle in a draw off pipe
or other receptacle whilst the hot water freed from sediment will alone ascend
through the flow circulation pipe.
A convenient form of trap for the sediment is an ordinary shaped piece or
coupling placed in the position indicated to the middle or horizontal branch of
which the uppermost member of the heater coil is connected, the flow circulation
pipe being connected to the upwardly-directed branch and the draw off pipe to
the downwardly directed branch of the piece or coupling. This draw off pipe
is led by an easy bend through the jamb of the mantel or to the front of the
kitchener in convenient position for drawing off hot water and is provided with a
draw off cock having a full bore corresponding to that of the reducing socket by
which the cock is connected to the pipe so as to afford a free outflow and ensure
the removal of all sediment collected in the draw off pipe every time that water
is drawn off for use.

1, ALICE MARY BUSHELL, of 39, The Broadway, Stratford, London, E. 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 water heating and circulating apparatus of that kind
in which a coil of piping placed wholly within the fire space itself; and therefore
in direct contact with the fire, is substituted for the ordinary high pressure boileri
heated by a special flue, as now arranged in kitcheners and self-setting ranges.
The coil in question may be of zigzag form disposed so as to extend across the
back and two sides of the fire space.
The object of the present invention is to cause the removal of all sediment from
the water and so prevent any solid matters being carried by the ascending current
of water into the flow circulation pipe where it would be liable to deposit in bends
or otherwise, and obstruct the free circulation of the water. This object is
attained by causing the water to come into direct impact with a vertical surface
which is substantially at right angles to the flow of the water at the point where
the circulation is most vigorous, that is to say immediately it leaves the heating
coil, so that the course of the water being abruptly changed from the horizontal.
to the upward direction the solid matters in suspension will be caused to settle in a
closed receptacle directly beneath such impact surface whilst the hot water freed
from. sediment will alone ascend through the flow circulation pipe.
The accompanying drawing, forming part of this Specification, illustrates in
Figure 1 a perspective view of a heating coil of the preferred form as applied
within the fire place of a kitchener having the oven on the left side only, the,
sediment collector being shewn at the right side of the jamb and also in Figure 2
in vertical section.
A is the heater coil as used for kitcheners with only one oven. It consists of a
zigzag coil of pipe comprising two vertical bends only, the coil extending across
three sides of the fire place, i.e. across the back and forwards at the two sides of
the fire space, the adjacent members of the coil being parallel and the coil as a
whole being made right or left handed so that when placed in position in the fire place
the highest member of the heater will be pext the oven just below the top thereof; ¿
as shewn.
a
The coil is made in one or more lengths of pipe, the two ends a', a', passing out;
through the "sham" and jamb on the right of the fire place. In the case of
kitchener with an oven at each side of the fire place. the ends of the heater,
would of course pass through the back of the rauge and so out at the side of the
jamb, as will be understood."
To the lower end a', is connected the return pipe B from the hot water cistern
above, whilst the horizontally extending upper end a³, is connected to the flow
pipe C through the medium of a sediment precipitator and trap, formed of a
tubular cross piece D, the part a³, of the heater being connected to the horizontal
branch d', and the flow pipe to the upper vertical brauch d', so that the heater
and flow pipe C are thus connected abruptly at right angles to each other. The
branch d³, is closed by a screw plug d whose inner end forms an impact surface
directly opposed to the flow of water through as, by striking against which the
flow is momentarily checked so as to give the sediment carried along with the
water an opportunity of escaping from the current. To the lower vertical
branch d, is connected a pendent tubular chamber E forming the intercepting trap
in which the sediment is collected, said chamber being provided with a screw

page_text: plug e at bottom which is removable for cleaning. Or instead of a screw plug a
draw off tap may be connected to the lower end of the chamber E so that any
sediment collected will be drawn off with the water used for common household
purposes.
Instead of a tubular cross-piece with a branch d³, closed by a plug d a plain
piece might be used, the interior of the cross-member of the piece itself
forming the impact surface.
Having now particularly described and ascertained the nature of the said inven--
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination, with a water heating coil of the kind described and with
the flow pipe therefrom, of a sediment precipitator and interceptor formed
essentially of an impact surface directly opposed to the flow of the water coming
from the heater whereby the direction of flow is changed abruptly from the
horizontal to the upward and vertical direction, and of a closed receptacle directly
below such surface.
2. The herein described sediment precipitator and interceptor for water
oirculation apparatus constructed substantially as specified.
