declare the nature of this invention (a communication to me from abroad by
Robert Fulton Harris, of East Sharon, Pennsylvania, U.S.A., Inventor,) to be as
follows:
This invention has reference to an improved heating apparatus for warming
railway cars and the like, and it consists in the combination with a tank which
is provided with a central opening in its top, of a stove which is provided with
flanges at its top and bottom, and also with draught openings. Suitable guide-
rods having springs thereon are arranged around the stove in combination with
a series of jointed rods, which are adapted to support the stove in a raised
position when required. An annular band is connected with the rods, and is
provided with a securing-pin. A weight is loosely mounted in the vessel on the
stove and is provided with a chain which is passed over a pulley, and is con-
nected with the securing-pin aforesaid.

COMPLETE SPECIFICATION.
An Improved Stove for Heating Railway Cars and the like.
I, WILLIAM HENRY MUNNS, of 106, 107, and 108, Victoria Chambers,
Chancery Lane, in the County of London, Patent Agent, do hereby declare
the nature of this invention (a communication to me from abroad by Robert
Fulton Harris, of East Sharon, Pennsylvania, U.S.A., Inventor,) 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 stoves for heating cars; and it consists in certain
improvements in the construction of the same, as hereinafter described and claimed,
the object of the invention being to provide against damage by fire in case of
accidents or derailment of cars on railways.
In the accompanying drawings,
Figure 1 represents a perspective view of a car-heater provided with my improve-
ments.
Fig. 2 is a vertical section of the same.
A designates a water-tank forming the base of the device, said tank being
flanged at the top and provided with packing to make a tight joint with the top
plate a. In the said top plate is a central circular opening to admit the stove B,
as hereinafter stated. Suitable packing c is secured in the plate a about said
central opening, so that the latter fits the cylindrical body of the stove. The
tank is also flanged at the bottom, the flange being perforated, so that it may
be secured to the floor of the car. The tank may be filled through an inlet
which is closed by a screw-plug b.
The cylindrical stove B is provided with a flanged at the bottom, which
extends somewhat under the top plate a, and thus connects the stove with the
tank, the stove being in position to sink into the tank, as hereinafter stated.
The stove is provided with a door C and with draught-openings e near its
bottom, said draught-openings being provided with doors which open inwardly

and are hung on friction-hinges to keep them in the desired position. The
said doors are also provided with inclined projections to impinge against the
top plate of the tank when the stove sinks therein and thus push the doors open.
The grate D rests on an inner flange of the stove a short distance above
the draught-openings and is secured in place by the hooks y, which extend from
the bottom of the stove to which they are secured. The said grate is formed
of a rim with grate-bars pivotally mounted therein, the said bars being loosely
connected at their lower edges with a cross-piece, and the central bar being
extended and squared to receive a key j, which may be applied thereto through
a key-hole for the purpose of shaking the grate. The securing-rods h extend
from the top to the bottom of the stove, as shown.
The standards or guide-rods E are secured at their lower ends to or within
the tank A and extend upward through the flange at the top of the stove.
At their upper extremities the said guide-rods are provided with braces m.
The spiral springs n are placed one on each of the rods E and are severally
connected with the tank A and with the flange of the stove, the said springs
being intended to draw the stove down in the tank when the supports of the
stove are displaced, as hereinafter stated.
When
The stove B is held in its raised position, as shown in Fig. 1, by means of a
series of removable braces, each of which consists of two rods o and p, which
are coupled together at r, one being provided with an eye or loop g.
the said removable braces are adjusted in position, supporting the stove, the
upper end of each rod o is in a recess or socket in the flange k at the top of
the stove and the lower end of the rod p rests in a socket in the top of the
tank. The rods o and pare prevented from displacement outwardly by a spring-
band F, which is passed through the loops of rods and extends around the
stove, the ends of said band being looped and secured to a forked arm s, which
is fixed to and extends from the casing of the stove B. The ends of the
spring-band are thus secured by means of a pin on the end of a chain I, the
pin being passed through the prongs of arms and the loops on the ends of
the band. The rods op forming the jointed braces, are prevented from lateral
movement by the arms t, which are fastened to and extend from the stove-
casing. The chain I is connected with a ball or weight u, which is placed
loosely in a cup or vessel L, secured to or formed on the top plate of the
stove, and said chain is passed over a sheave or pulley N, connected with one
of the braces m at the upper ends of the guide-rods E.
. When the stove is in position, supported by the jointed supports formed of
the rods op, with the band F adjusted about them and secured by the pine,
should an accident occur and the car become derailed or inclined in position
the ball u, being shaken from the vessel L, falls, withdrawing the pin from
the band F, thus releasing the jointed braces, the rods op giving way, when the
stove B is immediately drawn down, so that the water in the tank rushes in
through the draught-openings and extinguishes the fire.
Jindicates a smoke-pipe, which extends from the top of the stove and has one
section of it secured to the top of the car. This pipe is constructed to be auto-
matically extended or contracted after the manner of a telescope.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what I
claim is:
1. The combination, with a tank provided with a central opening in the top,
of a stove in position in said opening, a series of removable jointed braces
adapted to support said stove, a band connecting with and extending about said
braces, the extremities of said band being detachably connected, and a series of
springs adapted to draw said stove downward, substantially as and for the
purposes described.
2. The combination, with the tank provided with a central opening, of a

page_text: stove B, provided with flanges at its top and bottom and draught-openings,
guide-rods with springs thereon, a series of jointed rods o p, adapted to support
the stove in its raised position, a band F, connected with said rods and provided
with a securing-pin, and a weight loosely mounted in a vessel on said stove
and provided with a chain which is passed over a pulley and connected with said
securing-pin, substantially as and for the purposes described.
