PROVISIONAL SPECIFICATION.
Improvements in and connected with the Lids of Fuel Economizers
for Water-heating and the like.
I, Sir EDWARD GREEN, Baronet, of Wakefield, in the County of York, Fuel
Economizer Manufacturer, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is certain improvements in and connected with the
lids of apparatus known as "fuel economizers" by which the lids can be readily
removed and replaced from the top or outside for cleaning or inspection purposes,
also in forming them so as to present a flat or approximately flat interior surface
offering little or no obstruction in the top box passage way.
For the purpose of my invention, the lid proper is made tapered or conical with
its greatest diameter a little less than the smallest part of the opening or aperture
in which it is placed. The opening is also tapered corresponding with the taper of
the lid but when the latter is placed in position, a circular gap is left between the
sides of lid and the opening, which is closed by a copper or other ring to make the
joint. The joint ring can be readily removed and so allow the withdrawal of the lid
when desired.
In some cases the joint ring may be dispensed with, the lid being made to the full
size or larger than the opening, which is formed of oval shape as is also the lid, so
that the latter can be withdrawn from the opening by a quarter turn, which brings
its narrow part round to the widest part of the opening for easy removal of
the lid.
The lids are flat or approximately flat on the interior surface, so that a clear or
nearly clear unobstructed passage way is presented in the interior of the top box.
Dated this 18th day of October 1892.

COMPLETE SPECIFICATION.
Improvements in and connected with the Lids of Fuel Economizers
for Water-heating and the like.
I, Sir EDWARD GREEN, Baronet, of Wakefield, in the County of York, Fuel
Economizer Manufacturer, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
The object of this invention is certain improvements in and connected with the
lids of apparatus known as "fuel economizers" by which the lids can be readily
removed and replaced from the top, or outside, for cleaning, or inspection purposes,
also in forming them so as to present a flat, or approximately flat interior surface
offering little, or no obstruction in the top box passage way.
For the purpose of my invention, and as shown in the annexed drawings,
Figures 1 and 2, the lid A, Figure 1 (section) is made with its edge B tapered or
conical with its greatest diameter a little less than the smallest part of the opening,
or aperture in which it is placed. The opening C is also tapered corresponding, or
about so, with the taper edge of the lid A but when the latter is placed in position,
a gap D is left between the edge of lid and the opening, which is closed by a
copper, or other ring E to make the joint. The joint ring E can be readily sprung
[P71

page_text: or distorted for insertion, and be again set to circular form by the lid on its being
drawn tight by the bolt F, and bridge, or crossbar G.
In some cases, the joint ring E may be dispensed with, the lid A being made to
the full size, or slightly larger than the opening (see Figures 2 and 3) which is
formed of oval shape with tapered sides, as is also the lid, so that the latter can be
withdrawn from the opening by a quarter turn, which will bring its narrow part
round to the widest part of the opening for easy removal of the lid.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
:-
1. Constructing a fuel economizer lid with tapered edge, and forming an opening
in top box of fuel economizer (for a lid), of tapered shape but of smaller diameter
and fitting a ring between said edges for making a joint when the parts are screwed
up in the manner described, and substantially as shown at Figures 1 and 2 of the
drawings.
2. Constructing tapered edged oval lids, and tapered faced oval holes of fuel
economizers for joint contacts when screwed up, as and for the purposes set forth,
and as shown at Figures 3 and 4 of the annexed drawings.
