JACOB STONE, OF BELVIDERE, NEW JERSEY,-ASSIGNOR TO HIMSELF ANDv AB'RAM F. RANDOLPH, OFWASHINGTON, DISTRICT OF COLUMBIA.

. Letters Patent No. 81,113, dated August 18, 1868.

.- GEATE or RAILROAD-GAR STOVES.

TO ALL' WHOM IT MAY CONCERN: v

r Be it known that I, JACOB STONE, of Bividere, in the county of Warren, and State of New Jersey, have inyentedcertain Improvements in Stoves Suitable for Railroad-Cars and I do hereby declare that the following, taken in connection with the drawings which accompanyand form part of this specification, is a description of my invention sufficient to enable those skilled in the art topractise it.

The object of my invention is to furnish a stove adapted for use in railroad-cars, and which, by reason of its peculiarities of construction, will not, in case of accidentsor overturning of the cars, permit any fire to escape from it. i s

Figure 1 is a perspective view,

Figure 2a vertical section, and I Figure 3 a bottom view of a stovemade in accordance with my. invention.

A represents the body of the stove, and which I make of wrought 'boiler-iron,and B is an exterior cylinder surrounding the stove, and which I prefer to make of Russia iron,

' Between the fire-chamber of the stoveand the top cover, 0, whichcovers at the same time both the inner and outer cylinder, I place a perforated wrought-iron head or partition, D, and bolt the same securely to the inside of the stove. The perforations are for the purpose of allowing-a draught, but the head is intended to prevent any possibility of escape of fireor hcated'coals in case of an upset or concussion.

I E and F are two sliding doors nponthe stove, arranged to slide upand down,but not to swing upon hinges, as customary. These doors are also perforated finely, to admit air, and may be bolted securely after thestove is supplied with fuel, so as not to need to be opened until the car has stopped at a station.

G represents the grate, which is centrally hinged to an upright post, H, which is supported .in a cross-bar, h, and is made long enough to pass down through the ash-chamber, I, and through the bottom, K, of said chamher, and upon which it rests and" is sustained, as shown, and beneath this bottomit is connected with a lever, I, at whose outer end are two sockets, M and N, the former to receive a handle, for the purpose of agitating and raking the fire, without opening thel'ower door of the stove, and the latterto receive the same handle, in order I to turn the grate a little farther around, iuforder, to upset thesame when thegra te is to be emptied, this upsetting b eing caused by bringing a projection, O, on rim 0, to .coineide with a. notch or opening, P, iii-the grate.

It will. thusbe perceived that, without the need of incurring any risk arising .from accident because-of opening a door to rake, or even to overturn the whole fire, if need be, the fire in my stove can be managed and regulated without opening any door at all, all cinder-s and droppingcoals being constantly kept confined beyond all possibility of escape, except when fresh coal-is to be put in, which need only be done when the car is not in motion. g I I g The outer doors, Q R, upon cylinder B, are not made with'perforations, and should be made to fit snugly. SS are air-inlet holes, near the base of cylinder B, .to admit air into thefspace between the stove and the cylinder, and T Tare side perforations, near the top of the cylinder, to allow this air, after becoming heated by irradiation from the stove, to pass ,out into the car. i v

i The cover C is so made as to fit snugly upon both cylinders, and cover them entirely. U is the smokepipe, rising from the centre of this cover. o

Iucase of an overturning of the car, it will now be seen that, even if the outer cylinder be torn away by the accident, or the cover '0 displaced, or the stove be turned upside down, not a particle of fire can escape from any part of the stove,nor can the stove-cylinder or its head, D, be fractured, as neither of them are made of castiron or fragile material. i p

The post II confers great strength, in case of accident, by brncirig the grate at its centre, and thus preventing its fracture under severe shocks. j i

I claim the combination, with a ear-stove grate, of a central post,.arranged to be turned in its hearings, and to which the grate is centrally hinged, substantially as and for the purpose set forth.

I also claim the combination of the grate with the central post,when the latter extends downwards through the ash-chamber, and beyond its bottom plate, and is supported in the latter, so that the grate may be agitated or upset, substantially in the manner set forth.
