PROVISIONAL SPECIFICATION.
Improvements connected with the Lids and Seatings of Fuel
Economizers for Feedwater Heating and Steam Generating.
I, Sir EDWARD GREEN, Baronet and M.P. for Wakefield, of Heath Old Hall,.
Wakefield, in the County of York, Fuel Economizer Manufacturer, do hereby
declare the nature of this invention to be as follows:-
This invention relates to certain improvements connected with lids, or their
straps or bridges by which lids are secured in what are known as fuel economizers,
also in seatings of the boxes which such lids, straps, or bridges fit, in order to
obtain a good joint and a firm reliable hold of one to the other.
For the purpose of this invention, a recess or groove is formed in one face of the
lid, strap, or bridge, to abut against a depending lip of the box and consisting of
an internal joint. The side wall of the lid, strap, or bridge recess, annular or
otherwise, may be in touch with the inner periphery of the opening of the box, said
opening being oval for the easy insertion of the lid, strap, or bridge, or at a slight
distance therefrom, the inner periphery of each hole being parallel instead of being
tapered as is usual.
The lid so shaped may be fitted internally, and be held by a cover and bolt in
close contact at the seam or joint; or if a strap or bridge shaped to fit against a
depending lip of the box be used with or without the side wall, the external cover
would form the lid.

COMPLETE SPECIFICATION.
Improvements connected with the Lids and Seatings of Fuel
Economizers for Feedwater Heating and Steam Generating.
I, Sir EDWARD GREEN, Baronet, of Heath Old Hall, 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 ascertained in and by the following statement :-
This invention relates to certain improvements connected with fuel economizer
lids and boxes, also in seatings of the boxes, which such lids fit in order to obtain a
good joint and a firm reliable hold of one to the other, with or without a luting.
For the purpose of this invention, and as shown in the annexed drawings, a recess
or groove A is formed in one face of the lid B to abut against a depending lip C of
the box D, and constituting an internal joint. The side wall A of the lid may or
may not be in touch with the inner periphery E of the opening of the box D, or at
a distance therefrom, said opening being oval for the easy insertion of the lid B, the
inner periphery E of each hole being parallel instead of being tapered as is usual.
The lid so shaped may be fitted internally, as shown, or externally, and be held
by a cover strap or bridge G and bolt H in close contact at the seam or joint; or
if the strap or bridge be shaped to fit against a depending lip C of the box, the
external cover would form the lid.
In the drawings,
Figure 1 is a transverse section of a plain raised lipped lid with a depending
linned box hole.

page_text: Figure 2 a similar view of a plain lipped cover, and depending lipped box.
Figures 3 and 4 are longitudinal section and plan of the box and cover or bridge
for fixing the lid.
It will be understood that the recesses may be to any depth desired.
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 :-
The construction of lipped lids, and depending lipped holes of boxes of fuel
economizers and feedwater heaters for making sealing contact faces therein or
thereon without luting, as set forth.
