I, JOHN WILLIAM GUDGEON, of 17, Oak Terrace, Clayton Bridge, Manchester,
Engineer, do hereby declaresthe nature of this invention to be as follows:-
This invention relates to improvements in the construction and arrangement of
fittings and attachments for use upon or in connection with fuel economisers, the object
of the invention being to provide a more efficient means of enclosing the gearing and
chains so that the cold air may be excluded from the chambers of the economisers.
In carrying my invention into.effect I arrange a casing or frame work to carry the
gearing and chain wheels,, and I provide sight glasses or other transparent plates for
affording exposure of the desired working parts where so desired. The gear chamber
thus formed I carry from the economiser chamber frame or. casing by means of
hollow standards through which the working chains pass into the chamber; within
these hollow standards I cause hollow truunior like chain arms to enter, the upper
part of the bottom standard or hollow trunnion being dished or hollowed out to
form a receptacle for packing or other sealing or jointing material.. 1 carry the
whole of the gear and wheel casing by suitable brackets or standards, and I make the
trunnion arins through which the chain passes from chamber or casing adjustable
by means of serows and nuts or by means of springs which keep the flanges of the
trunnions in close contact with the under surface of, the gear case or chamber.
I employ any well known system of chains and gearing for driving the same, and
I employ my improved air sealing and enclosing fittings and apparatus to any
ordinary type of economiser, altering the brackets, casing, and trunnions to suit the
particular type of economiser to which the fittings are to be applied.
Improvements in Fittings for Heating Boiler Feed Water.
I, JOHN WILLIAM GUDGEON, of 17, Oak Terrace, Clayton Bridge, Manchester,
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 stateinent:―
This Invention relates to improvements in the construction and arrangement of
fittings and attachments for use upon or in connection with fuel economisers, or

efficient means for enclosing the chain gearing so that the cold air may be excluded
from the chambers of the economisers.
In carrying my invention into effect I arrange a casing or frame work to enclose
the chain gearing, and I provide sight glasses or other transparent plates for
affording exposure of the working parts where so desired. The gear casing.or
chamber is carried by brackets from the economiser framing. With the lower part
of the casing I form hollow standards through which the working chains pass into
the chamber, and within these hollow standards I cause hollow trunnion like chain
arms to enter, the lower part of such arms seating upon the economiser, an air tight
joint being made between the surfaces. The trunnion arms are made adjustable
preferably by means of screws and nuts.
adapt any invention to existing economisers, and employ my improved air
sealing and enclosing fittings and apparatus to any ordinary type of economiser,
altering the brackets, casing, and trunnions to suit the particular type of economiser
to which the fittings are to be applied.
In the accompanying sheet of explanatory drawings to be hereinafter referred to.-
Figure is a side elevation and Figure 2 a sectional end elevation of an
economiser enclosing apparatus constructed and arranged in accordance with my
invention.
The chamber or casing is made in two parts, as A and B which are jointed
together with the central brackets or bearings C C arranged between them with
air tight jointing material between the meeting surfaces. The lower segment B of
the casing is provided with hollow chain arms as B1 B2 whose lower ends are arranged
to receive the screwed ends of the hollow standards D D!, the lower ends of such
standards being seated upon the economiser chamber frame or casing E, with an
air tight joint between the surfaces. With the nuts 61 62 air tight joints can be
readily inade between the parts B and D and B and D. Through the glass or other
sight doors bthe working of the chain can be readily inspected. By the set screw F
the collar or shoulder G on the shaft G can be sufficiently tightened against the
bracket C to prevent entrance of air from between the shaft and its bearing. A
similar entrance of air from the bracket C¹ is prevented hy the closed end carrying
the set screw.
Having now particularly described and ascertained the nature of my said
invention and what manner the same is to be performed, I declare that what I
'claim is
An enclosing chamber or casing for the gearing of a fuel economiser with air
sealing or jointing fittings, substantially as described and as illustrated.
Dated this 13th day of December 1897.
