Letters Patent No. 92,753, dated July 20, 1869.

RAILROAD-GAR HEATER.

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

To all twhom it may concern,.-

Be it known that l, CYRUS SANBORN, of Chichester, in the county of Merrimack,l and State of New Hampshire, have invented a new and improved Safety- Stove for Railroad-Gars; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a ont view of improved stove.

Figure 2 is a vertical cross-section of the same.

Similar letters 'of reference indicate corresponding parts.

My invention has for itsobject vto nni'sh an improved railroad-stove, which shall be so constructed and arranged, that should the car or stove be acciden tall-y overturned, the iire may be extinguished before it can do any damage, and which shall at the same time be simple'in construct-ion, and will occupy small space in the car; and

It consists in the construction and combination ofl the various parts of the stove, as hereinafter more fully described.

The body ofthe stove, which may be of any desiredv which rest upon and are secured to angesformedupon the sides oi' the stove, and upon the top of the partition C.

The reservoir D is made a little smaller than thecornpartment B of the stove, so that an air-space may be left all around said reservoir D, to preventthe water in said reservoir from being heated, the airchamber in the partition O also tending to prevent the water in said reservoir Afrom being heated.

The partition C does not extend to the top of the stove, the space above. the upper edge of said partition being occupied by a plate, or valve, E, pivoted at the upper ends of its end edges, to the body ofthe stove, so as to prevent the smoke and other products of combustion from passing into the compartment B.

The plate E is pierced with a hole, to allow any steam that may be developed from the water inthe reservoir-D, to escape into the compartment A,'and pass oli' with the products of combustion.

` F is the top plate of the stove, through'vwhich is formed an opening, f1, for the escape of the products of combustion, and which is provided with a pipecollar to receive the smoke pipe. l To the under side of the ,top'pl'ate F ot' the stove, upon the opposite sides ot' the egress-opening for the smoke, are pivoted two swinging plates or valves G, as shown 'in g. 2,.so that should the' stove be overtmned in any direction, one or the other of said plates or valves may drop down over and closethe said openglu the top F of the stove, directly over the reservoir D, is formed an opening, f2, for convenience in supplying said reservoir with water when required.

The opening j'2 should be covered with a screw, or other lock-cap. v

vH is the door, through which the fuel is introduced into the tire-chamber, which door should be supplied with a draught-opening, which is closed with a damper, A

I, so constructed and weighted, that when the stove is in its proper position, it will remain either open or shut, but should the stove be overturned, the said damper, from its own weight, will close the draughtopening.

By this construction, should the stove or car be overturned in any direction, the water fro1n`the reser-' voir D will ilow into the vcompartment. A,. and extinguish the tire before it can do any damage, the valves G and damper I at the same time closing the smoke anddraught-openings, so that neither lire nor water can escape u-n'til theiire has been extinguished.

Having thus described myinveution,

- What I claim as new, and desire to secure by Let-- forth.

CYRUS SANBORN.
