Improvements in Water Heaters.
I HOWARD THEOPHILUS WRIGHT of 16 Great George Street, in the City of
Westminster, Engineer do hereby declare the nature of this invention to be as
follows:-
This invention relates to water heaters more especially those of the Berryman
type in which the water is heated by contact with a number of heated tubes
arranged in a vertical casing but the invention may be applied to heaters of any
description wherein it is desirable to provide means for readily removing the casing,
and it is the object of my invention to so arrange the apparatus that the casing
can be readily removed for cleaning the tubes or other purpose without disturbing
any other parts of the apparatus.
With this object I make the connections for both the inlet and outlet of water in
the body casting of the apparatus or that part below the casing and I carry up a
pipe from the outlet connection inside the casing to the upper part of the said
casing.
Around the said casing I erect a suitable number of standards or columns with
rollers at top over which pass chains or ropes one end of each of the said chains or
ropes being connected to the casing and the other end carrying a counterweight.
The casing may be provided with guides to run along the standards or columns and
these may take the form of forks which embrace the standards or columns, these
forks also forming convenient attachments for the chains or ropes to the casing.

I, HOWARD THEOPHILUS WRIGHT of 16 Great George Street, in the City of
Westminster, 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 :-

description wherein it is desirable to provide means for readily removing the casing,

any other parts of the apparatus. With this object I make the connections for
both the inlet and outlet of water in the body casting of the apparatus or that

and the other end carrying a counterweight. The casing may be provided with
guides to run along the standards or columns and these may take the form of forks
which embrace the standards or columns, these forks also forming convenient
attachments for the chains or ropes to the casing.
In the accompanying drawing I have illustrated what I consider the best method
of carrying my invention into effect. Figure 1 is an elevation and Figure 2 a
plan. Figure 3 is a vertical section and Figure 4 is a horizontal sectional plan.
The body casting or that part below the casing is marked A and in it are the
openings (a a³) and connections respectively for the inlet and outlet of water, the
pipe B being carried up from the outlet opening to inside the space enclosed by
the casing as shewn. C is the casing bolted to the part A so that it can be
disconnected therefrom. Around the casing I erect on the base D. columns E
connected together at top by the connecting ring or segmental struts e the said
columns having rollers e² at top and over these rollers pass chains carrying at
one end counterweights and at the other end f³ being connected to the casing.
g are forks on the casing to run along the columns E as guides.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is
-
1. In water heaters making the inlet and outlet for water in the body casting or
that part below the casing and carrying up a pipe from the outlet connection to
the upper part enclosed by the casing and making the casing so that it can be
raised or removed substantially as hereinbefore described.
2. The arrangement and combination of parts constituting the water heater with
counterweighted raisable casing substantially as hereinbefore described and shewn
in the accompanying drawings.
