SPECIFICATION forming part of Letters Patent No. 303,566, dated August 12,1884.

Application filed March 11, 1884. (No model.) I

heating purposes; second, that can be easily repaired; third, that is made of materials which can be had in almost every town and village, so that any necessary repairs can be done at home 5 fourth, that is of such shape and so constructed as to be placed in any heatingstove, so that any family having one of these generators can, by placing it in a stove and-by adding conducting-pipes and radiators, heat their dwellings by steam at the minimum cost for fuel; fifth, that can be used for heating railroad-cars by steam with the smallest pos sible amount of fire, thereby doing away with most of the danger arising from the stoves and heaters at present used for heating cars, when, in cases of accidents, the same are overturned. In such cases the waterin my generator,when overturned and broken, will extinguish the fire, and as a few pounds of steam-pressure would be amply sufficient for heating purposes, there could be little or no danger from the escaping steam. Therefore,with my generator for heatingcars one of the greatest dangers from collision or other railroad accidents would be removed, namely, fire.

My generator can be readily set in masonry,

as well as attached to an ordinary heatingstove.

In the drawings, Figure l is a perspective view of the generator, showing the heat-fines running through the main boiler and the watertubcs 011 the outside with their connections, also the gages, &e. Fig. 2 is aview of the stove-cap and the smoke-pipe, showing the bolts for sup porti u g the generator when placed in a stove. Fig. 3 is a view of the generator as it appears in a stove. Fig. 4 is a view of the cap I for supporting the generator.

a parlor-stove with the generator attached. Fig. 5 is a view of an ordinary sheet-iron stove with the generator attached. a

In the drawings, similar letters of reference designate corresponding parts in all the figures.

A is the main boiler or reservoir. B are the water-tubes connected at the top and bottom of the main boiler A, as shown in Fig. 1. G are the heat-fines running through the boiler A. D is the safety-valve. conducting the steam. F is the water-column. G is the glass water-gage. H are the bolts in I is the cap for the stove. J is the smoke-pipe. K is the feed-pipe or pump-connection. I is the check-valve. M is the drip to the watergage. N are the try-cocks on the water-col.- umn F. O is the blow-off pipe. P is the steam-gage,-

E is the pipe for XVhen the generator is placed in a stove or set in masonry, no part of it comes in contact with the outer wall of the stove or of the brickwork butin either case the generator will be supported by the bolts in the cap, thus allowing the heat to pass freely around the small water-tubes, as well as through the heat tubes or fiues inthe main boiler.

My generator is constructed out of regular sizes of wrought steam-pipe, and is very simple in construction, very cheaply made, and easily repaired and kept clean. Being made in different sizes, it can readily be attached to any ordinary heatingstove by selecting the proper size for the stove in which it is to be placed. It can also be satisfactorily set in masonry. By the use of this generator a great saving in fuel can be had for the amount of steam generated, and this is largely due to the fact thatall the heat possible is utilized, as above shown. My invention can be satisfactorily employed in all ordinary heating purposes, especially for heating houses and cars; and in cases where steam is employed for culinary purposes my invention will be found valuable. It will also supattached to the sides of said cylinder by means of nipples and ells, and fire-tubes extending through the interior of the said cylinder, sub stantially as and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand in the presence of two witnesses.
