COMPLETE SPECIFICATION.
An Improved Arrangement for Heating Water for Domestic
Purposes.
I WILLIAM MCCAIG of 665 Cathcart Road, in the County of the City of
Glasgow, North Britain, Gas and Ventilating 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 has for its object to dispense with the necessity of providing a
boiler at the back of the kitchen fire to heat water for domestic purposes and to
provide an arrangement which will accomplish the same object more expeditiously
and with less consumption of fuel, and being under the control of the householder,
no explosions such as frequently occur in frosty weather with the ordinary boiler
at the back of grate can take place.
In order that my invention may be properly understood and readily carried into
effect I have hereunto appended an explanatory sheet of drawings showing my
improvements as applied to an ordinary kitchen range.
Figure 1 is a front elevation of a kitchen grate or range part of which is broken
away to enable my improved arrangement for heating water to be properly
illustrated and understood.
Figure 2 is a plan of the same partly in section.
In carrying my invention into practice I so construct the fire bars A that a free
water communication A¹ is made through them. In this space or passage A' the
water is heated by the radial heat of the fire. The supply pipe B, which is in
direct communication with the supply cistern, is connected to the said hollow
bars A at their lower ends by means of a swivelling joint stuffing-box, gland and
screw coupling C. The swivel stuffing-box arrangement is fastened to the grate
or range from the outside by a nut screwed to a bolt cast on the arrangement at E
and C, and this allows the bars A to swing with perfect ease.
At the upper
A sludge cock may be placed on the branch extension pipe B¹.
end of the said bars A, the water when heated rises and is led to the pipe D, to
which it is connected by the swivelling joint and connections E. The circulation
of the water takes place in a manner indicated by the arrows Figure 1.
In frosty weather when danger of explosion frequently occurs, or at other times
at the complete will of the householder the swivelling connections C and E permit
of the bars A being turned in to the side of the grate, out of contact with the fire,
wheu a fire-brick or iron plate may be placed between them and the fire. The
position of the fire bars A when turned round to the side of the grate, and the
path described is shown in dotted lines in Figure 2.
The ordinary solid bars sold with the grate or range are then dropped into the
position hitherto occupied by the hollow bars A.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The general arrangement and combination of the parts constituting the improved

page_text: arrangement for heating water for domestic purposes substantially as hereinbefore
described and illustrated on the accompanying sheet of drawings.
Dated this 3rd day of August 1895.
