We, CHARLES WESSLEY HULLINGS, (Sewing machine dealer) of 209, High Street,
Burlington, and JOHN SUNDERLAND VALENTINE, (Dealer in Clothing and Shoos) of
318, Broad Street, Burlington, in the County of Burlington, and State of New
Jersey, United States of America do hereby declare the nature of this invention to
be as follows:-

This Invention relates to improvements in locomotive fire boxes in which an arched
hollow baffler plate supplied with water from the tank extends from the top of the
furnace opening in lieu of a door inwards and downwards over the grate so as to
prevent the cold air entering from striking the crown sheet.
The objects of the invention are to ensure a circulation of water through the buffler
plate in order to prevent burning out, and to facilitate its removal for repair or
otherwise.
The baffler plate is constructed preferably of copper and its outer end is formed
with a hollow upward and laterally projecting flange, the closed chamber of which
forms an extension of that in the baffler plate and which rests against the outside of
the furnace wall and around the top of the opening therein. The flange is provided
with short tubes which are connected to fixed tubes on the wall of the furnace so
that the baffler plate may be put into communication with the boiler and is removably
supported in position, the tubes on the furnace wall being furnished with cocks which
are closed when the baffler plate is to be removed. The top of the flange is provided
with short tubes adapted to be detachably connected to pipes which extend along on
either side of the boiler and communicate with the pipes through which the water is
discharged by the injectors into the boiler at the forward part thereof, and also with
pipes which communicate with the feed pipes leading from the pumps into the boiler
in the ordinary manner. All these connections are provided with suitable valves and
cocks and the injectors and pumps are connected in the ordinary manner with the
water supply pipes. A discharge pipe leads from the bottom of the flange of the
baffler plate to the ash-pan for emptying the baffler plate when it is to be detached.
With this arrangement, when the boiler is to be fed by the injectors by closing
and opening certain of the cocks the water is drawn from the tank through the pipes

page_text: connected therewith and is forced into the bafiler plate and thence into the boiler,
and similarly when the hoiler is to be foil by the pumps, so that in both cases a
circulation of water through the baller plate is ensured. The arrangamont, however,
is such that the injectors and pumps may feed directly into the forward part of the
boiler when desired.
In order to guard against the steam generated in the baffler plato from forcing the
water back in the feed pipes before the injectors or pumps are set to work, we provide
cach of the pipes with a spring-pressed check valve. When the injectors or pumps
are not at work, the steam in the baller-plate and the springs of the valves will forco
tho said valves against their respective seats whereby the steam will be shut off from
forcing the feed water back in the feed pipes. Upon the pumps or injectors being
sot to work, the check valves will be forced from their seats and the feed water will
have a clear passage to the bafiler plate.

We, CHARLES WESSLEY HULLINGS, Sewing-Machine Dealer, of 209, High Street,
Burlington, and JOHN SUNDERLAND VALENTINE (Dealer in Clothes and Shoes) of
318, Broad Street, Burlington, in the County of Burlington, and State of New Jersey,
United States of America, 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 particularly to an improvement in the fire-boxes of locomo-
tives in which an arched hollow baffler-plate supplied with water from the tank
extends from the top of the furnace opening in lien of a door inward and downward
over the grate so as to prevent the cold air entering at the opening from striking the
crown sheet and thus to consume the smoke and cinders in the furnace. The objects
of the invention are to secure a circulation of water through the hollow baffler plate
so as to effectually prevent its burning out and to facilitate its removal for repairs or
.renewal.
The Invention consists of certain novel, features of construction and combinations
of parts, hereinafter fully described and distinctly pointed out in the claims.
Reference is to be had to the accompanying drawings forming part of this speci-
fication, in which figure 1 is a side, partly sectional, elevation of a part of a locomotive
to which the improvement has been applied. Figure 2 is an enlarged rear end
clevation of the furnace and boiler of same. Figure 3 is a plan view of the rear part
of the boiler and furnace. Figure 4 is a sectional side elevation of the same, on
line - figure 2.
Similar letters of roference indicate corresponding parts in all the figures.
A is the furnace, B the furnace opening, C the boiler, D the grate, E the furnace
deflector, F one of the two boiler feed pumps, G one of the two injectors, and H H
the two supply pipes leading from the water tanks of a locomotive, all of which parts
may be of the ordinary description shewn.
From the top of the furnace opening B a transversely arched hollow baffler plate I
constructed, by preference, of copper is arranged to project inward and downward to
near the normal level of the fuel on the grate D, for the well-known purpose of
deflecting the air entering the opening B upon the fire and consuming the gas and
sparks produced thereby. The outer end of this hollow baffler plate I is formed with
a hollow upward and laterally-projecting flange I¹ the closed chamber of which
forms an extension of that in the baffler plate, and which is arranged to rest against
the outside of the furnace wall A¹, around the top of the opening B therein.
To opposite sides of the hollow flange, are rigidly attached short tubes J J¹ com-
municating with the interior thereof and adapted for connection by unions J2 with
short bent tubes K K' respectively fixed to the furnace wall A' and communicating
with the boiler so that the baffler-plate is thereby both put in connection with the
boiler and removably supported in position. The fixed tubes K K¹ are each provided
.

page_text: with a cock K² so that they can be readily closed previous to detaching the baller-
plate. From the top of the hollow flange I' on either side, lead other short tubes L,
also adapted for detachable connection by unions L with the ends of pipes M M
which are carried laterally and oppositely along the outside of the wall A' and forward
on opposite sides of the boiler to a connection with the pipes N N' which discharge
as usual from the two injectors G into the boiler C at the forward part thereof. The
ends of the pipes M Madjacent to the unions are provided with cocks M² for
closing them previous to detaching the haflor-plate. Pipes 0 0¹ provided with
cocks 0, are also run from the pipes M M to the feed pipes P having cocks P*
leading from the pumps F into the boiler in the ordinary manner, the pipes M. M'
having long-handled cocks M, adjacent to their connections with the discharge
feed pipes NN and the pipes N'N' also having long-handled cocks N2 betwhen said
connections and their boiler connections. The injectors and pumps are connected, as
nsual, with the water supply pipes H H by valvod pipes QQ and RR respectively.
S is a discharge pipe arranged to lead from the bottom of the hollow flange on the
baffler-plate out upon the ash-pan for emptying the bafflor-plate when the same is to
bo detached.
With the arrangement described, when the boiler is to be fed by the injectors G,
by closing the cocks N' and opening the cocks M the water drawn from the tank
through the pipes H Hand QQ will be discharged through the pipes M M' and
tubes L L into the baffier plate and thence through the tubes J J and K K' into
the boiler so that the desired circulation through the battler plate will be obtained.
When the hoilor is to be fed by the pumps F, by closing the cocks P to Pand
opening them to O and opening the cocks 0, the water drawn from the supply
pipes H H and R RI will be pumped through the pipes O O' and M M and
LL' into the bafflor plate and thence as before, into the boiler so that in this
way also a circulation of water through the battler plate may be obtained. By
closing the cocks M' and O' and opening the cocks N and P, the injector and pump
may be caused to feed directly into the forward part of the boiler when so desired.
All the baftler-plate connections, feed pipes, and valves, being located outside the
boiler, the baffler plate may be readily detached and replaced without the necessity of
putting out the fire. By thus causing the water to circulate through the baffler platu,
it may with perfect safety be brought so close to the fire as to deflect all the air
theroupon and thus entirely consume all smoke and cinders.
In order to guard against the steam generated in the baffler-plate from forcing the
water back in the feed pipes M M before the injectors or pumps are set to work, wo
provide each of the pipes M M' with a check valve E' located preferably near the
cocks M of said pipes. When the injectors or pumps are not at work, the steam in
the baffler plate and the springs of the valves will force the said valves against their
respective sents e whereby the steam will be shut-off from forcing the feed water back
in the feed pipes M M. Upon the pumps or injectors being set to work, the check
valves E will be forced from their seats and the feed water will have a clear passage
to the baftler-plate. Although we have shewn the check valve in one of the feed
pipes only, it will be understood that both are so valved.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, we declare that what wo
claim is :-
1. The combination with the locomotive boiler and fire box provided with a fuel
opening, of the hollow baffler extending through the upper part of the fuel opening
