PROVISIONAL SPECIFICATION.
Improvements in Steam Boiler and other Furnaces.
I JAMES WHITTAKER of 33 Avenue Parade, Accrington, in the County of
Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows:-
My improvements relate to steam boiler and other furnaces, the dead plate and
back bearer being formed and arranged to receive water troughs in combination
with the fire bars, which may be either stationary or movable by suitably designed
mechanism and can be used with forced draught or otherwise.
The object is to obtain a better combustion of the fuel and prevention of
smoke.
In my invention the fire bars are so arranged that each bar has a seperate water
trough and the troughs can be made in sections of one or more, and connected by
couplings joining the water spaces so that the water circulates through any or all of
the water troughs and is in contact with the fire bars.
The water troughs are so arranged as to allow sufficient space for the air
passages in combination with the steam arising from the water in troughs becoming
heated by being in contact with the fire bars, thereby causing an increase of
combustion and prevention of smoke. The dead plate is designed and arranged
with cover plate for ends of fire bars, and to receive the ends of bars, and water
troughs, bearings for shaft with cranks formed at opposite centres, and for
attachment of driving mechanism.
The back bearer is formed to receive fire bar end arrangement, and for delivery
of waste or clinkers, or otherwise.
The fire bars are arranged to rest on a movable prop at one end, and to fit on to
a connection to crank bearings at the other, so as to be removable at pleasure, or
otherwise when not intended to be movable bars.
The crank shaft is connected by suitable driving apparatus arranged to be
worked automatically, or disconnected and movable by hand.
The fire bars have a reciprocal or wave like motion, alternate bars moving in
opposite directions thereby carrying the fuel slowly forward, and passing the waste.

The water to be supplied to the troughs from water guage or other suitable
rrangement which may be automatic or otherwise.

I JAMES WHITTAKER, of 33 Avenue Parade, Accrington, in the County of
Lancaster, 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 improvements relate to steam boiler and other furnaces and may be described
as follows reference being had to the accompanying drawings.

page_text: Fig. 1 is a longitudinal section of fire bar and trough with dead plate and back
bearer, showing mechanism for movable bars.
Fig. 2 is a part end view of Fig. 1.
Fig. 3 is a plan of fire bars, showing troughs and connection for movable bars.
Fig. 4 is a longitudinal section of non movable fire bar and trough with dead
plate and back bearer.
The dead plate A with bracket A' and back bearer B is formed and arranged to
receive water troughs C. C. in combination with fire bars D which may be either
stationary or movable by suitably designed mechanism K Fig. 1 and 2 and can be
used with forced draught or otherwise. The object is to obtain a better combustion
of fuel and prevention of smoke. In-my-invention the fire bars are so arranged
that each bar has a separate water trough C. C. and the troughs can be cast in
sections of one or more and connected by pipes E. E. joining the water spaces so
that the water circulates through any or all of the water troughs and is in contact
with the fire bars. The water troughs are so arranged as to allow sufficient space
for the air in combination with the steam arising from the water in trough becoming
heated by being in contact with the fire bars, thereby causing an increase of
combustion and preventing smoke. The dead plate A is designed and arranged
with cover plate F for end of fire bars D and to receive the ends of bars and
water troughs, bearings for shaft with cranks formed at opposite centres, and for
attachment of driving mechanism.
The back bearer B is formed to receive fire bar end arrangement and for
delivery of waste or clinker or otherwise, and removal of same. The fire bars are
arranged to rest on a movable prop H. Fig. 1. at one end, and to fit on to
a connection J. Fig. 1. to crank bearing at the other, so as to be removable at
pleasure, or otherwise when not intended to he movable bars.
The crank shaft 1 is connected by suitable driving apparatus K. Fig. 1. and 2.
as follows:2 is a groove pulley, 3 catch box, 4 bevil wheels, 5 worm and wheel,
and 6 hand wheel which can be worked automatically by a band from motive
power, or disconnected by catch box 3 and movable by hand wheel 6.
The fire bars have a reciprocal or wave like motion, alternate bars moving in
opposite directions thereby carrying the fuel slowly forward and passing the waste
or clinker off at the end. The water is to be supplied to the troughs by connection
to pipe L. Fig. 5. from water gauge or other suitable arrangement which may be
automatic or otherwise. I wish it to be understood that I do not confine myself to
the particular design of bar shown in drawings as these may be varied to suit the
different classes of fuel used.
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 :-
1. The combination of dead plate A and bracket A¹ with water trough C and
back bearer B substantially as described and shown.
2. The combination of dead plate A bracket A' water trough C back bearer B
with bar D and prop H substantially as described and shown.
3. The combination of dead plate A bracket A' water trough C back bearer B
bar D prop H with connection J and mechanism K for movable bars, substantially
as described and shown.
Dated this 22nd day of April 1896.
