SAFETY-STOVE FOR RAILROAD-CARS.

The Schedule referred to in these Letters Patent and making part of the same.

To ai! whom it may concern.-

Be it known that I, C. J. SMITH, of Norfolk, in the county of Norfolk, and State of Virginia, have iuvented certain new and useful Improvements. in Safety-Stoves; and I do hereby declare that the following is a full, clear, and exact description of the saure, reference being had to the vaccompanying drawing, and to the lette'rs of reference marked thereon,

making part of this specification, in which Figure 1 is longitudinal sectional View.

Figure 2 is a transverse sectional View on the line I-I, tig. 1 l

Figure 3 is a transverse sectional view on the line J-J, iig. l.

Figure 4 isa transverse sectional view on the line H-H, fig. 1.

Figure 5 is a front view of the stove.

Figure 6 is a plan view of the wire guard in the upper portion of the combustion-chamber.

Figure 7 is anedge v iew of the same.

' Figures 8, 9, and 10 are detailed views of the doorfastening, and the va'rious features that compose the same.

i rlhis invention relates to a stove that is intended particularly for railroad-cars, but which can also be advantageously used for other purposes, especially on steamboats.

This stove can be used with perfect safety, and is so constructed that it will withstand any amount of rough usage, the tire all the while `being maintained with perfect safety. Even lshould an accident occur of suicient violence to completely overturn the stove, owingr to the complete and perfect arrangement of the mechanism by which the door is fastened and held, it is impossible for the same to escape.

It is anadmit-ted fact, that'in most of the fearful railroad :Incidents which have occurred of late, the peculiar horrors that rendered the Sallie so disastrous and distressing, were traceable solely and entirely to the fact thatI the violence of the concussion which threw the car from the track, owing to the style of stove used, caused it to empty and scatter its burning coals among the passengers, and the burning fuel thus poured out soon caused the wood-work of the car `to ignite, and, as a necessary consequence, the entire oar While my stove is simple and practical in construction, st-ill it can safely be used without the slightest.

fear of the result mentioned, no mattei' how sudden and violent the concussion which throws the car from the track may be.

To accomplish this, I use a lstove constructed entirely of wrought metal,l withl a wire guard in the upper portion of the comhustion-chamber, and a false bottom, which is secured in the ash-chamber below the grate. The door I securely fasten by means of a bolt, slide, and weighted handle, so arranged, that while they can be readily operated, still,when once fastened,no motion or overturning, no matter in what direction the latter may be, will free the same and allow the door to open. y

To enable others skilled in the art to make and use my invention, I will nowproceed to describe its construction and operaiiou.

.Al is the ash-chamber, which is circular'in form, and constructed with a. `flange, a, by means of which it is firmly bolted or otherwise secured to the door. rllhis ash-chamber is provided with a door and draught openings; There is also in its lower section a series ot' holes, a' c', to allow of tne passage of a current of cold air between the bottom of the ash-pit and the door.

B is the fire-pct, cone-shaped in form, and is seated in the ash-chamber A', and lirinly bolted therein. It enters the ash-chamber A* such a distance, that when fastened, its lower edge is immediately above the draught-openings.

These draught-openings are opened and closed at pleasure by Ineans of an ordinary valve-plate and handle.

The fire-pot B is constructed withv a Lnge, b, on which rests the'liange e of the' combustion-chamber A, which is also cone-shaped in form.

By means of vthese flanges, b c, the two sections of the stove are rmly held together.

Over these iianges is placed a suitable cap-plate, A, which gives an exceedingly neat appearance to the stove.

The stove, thus formed, is constructed of wroughtiron, and its lower section lined with fire-clay.

G is a false bottom, and is constructed with a flange, d, by means of which it is secured in the lower section ofthe ash-chamber A. This false bottom, G, is sufficiently far above `the openings c a to allow an unobstructed passage for the cold airubetween it and the door.

E' is the re-grate, and is constructed, inserted, and operated in the usual manner.

A little above midway ofthe combustion-chamber A is lirmly secured a wire guard, F, whose diameter is exactly that of the portion of the stove where it is secured. In case of the stove being overturned, this wire guard preventsthe tire from escaping in that direction, while the false bottom G will prevent its escape in the opposite direction.

G.G are two doors, and are irmly hinged to the stove in the usual manner, one closing an opening in the ash-pit, and the other closing a similar opening in the combustion-chamber, for the reception of fuel.

To each of these doors is secured a plate, on which rests and works the fastening, which is constructed as follows: v

l1l is a slotted casing, in which freely works the bolt B'.

This casingis 'so cut away at a given point, that when the door is fastened by the bolt being in the staple H2, the weighted handle .1) can be freely ino\ ed up and down, but in no other direction, until brought in a, line with the slot E, in the centre of the casing H. So it will be seen that when the bolt B is once inserted in the staple H2, simply by dropping the weighted handle D, the doonis securely fastened, all lateral play beingz,r im possible, so that, should the stove be overturned or thrown on its side, the door cannot he opened.

In the upper portion of the chamber A is a suitable opening, to which the pipe may be connected 'Having thus fully described lny invention,

What l claim therein as new, and desire to secure by Letters Patent of the United States, is-

l. The chamber A, tire-pot B, each cone-shaped in forni, and united by flanges b c, and cap-plate A, ashchalnber A, false bottom G, openings a' a, and wire guard F, when the salue are so coulbinedalnl arranged as to forin a safety-stove, substantially as described.

2, Securing the door by casing, bolt, and weighted handle, when the same is s0 arranged as to operate substantially as described, as and tor the purpose spe- V
