UNITED STATES PATENT OEEICE.
H. J. DAVISON, OF NEW YORK, N. Y.
IMPROVEMENT IN ARRANGEMENT 0F AV WELDING-FURNACE AND STEAM-BOILER.
Specification forming part of Letters Patent No. 50,562, dated October 24, 1865.
To all whom it may concern.-
Be it known that I, H. J. DAvlsoN, of 229 Broadway, in the city, county, and State ot' New York, have invented a new a nd Improved AArrangementofaVelding-Furnace in Relation my invention. Fig. 2 is a transverse vertical section in the plane indicated by the line 00 a: in Fig. l. Fig. 3 is a horizontal section in the plane indicated by the line y y in Fig. l.
Similar letters of reference indicate correspondin g parts iu the several gures.
The gaseous products of the combustion of the fuel used in the furnaces employed for the welding of wrought-iron tubes and other articles escape from such furnaces at a very high temperature; and as steam power is commonly used for driving the machinery u sed in connection with such furnaces, the said gaseous products may be used veryadvan tageously for heating the boilers in which the steam is generated, the heat of such gaseous products (if not all, sucient, with a proper construction and arrangement ofthe furnace and boiler, to generate the steam required) being sufficient to reduce very greatly the quantity of fuel required to be used in aseparate furnace. It is desirable in carrying out such an arrangement that provision shall be made for heating the boiler before the welding-furnace is in operation, as the blower of the welding-furnace must be started before the said furnace can be got into operation, and the steam from the boiler will be used for driving the blower; but this provision has not been conveniently made in previous arrangements of the boiler and welding-furnace.
The object of this invention is to use the heat of such gaseous products in the most economical manner, and to provide conveniently for the heating of the boiler before the-weldingfurnace is in operation, and the invention consists in anovel arrangement of the welding-furnace in relation to a boiler and within the set cape and which takes the place ofthe ehimney of an ordinary welding or other reverberatory furnace, being at the opposite end and nearly under the middle of the boiler. The tubes or other articles to be welded are placed on the reverheratin g chamber ot' the said furnace through an opening in one sideot the said furnace and the boiler. The fuel is supplied tothe fire-place a` through an opening, c, from, a reservoir, d, in the nearest end wall ot` the said furnace and boiler-setting, the' fuel 'being heated in the said reservoir and being pushed into the furnace as required by means of suitable implements inserted into the openT ing c, which extends through the exterior ot' the said wall.
Un der the other end ofthe boiler is a furnace, D, Fig. l, substantially like the furnace commonly employed under a steam-boiler. This furnace is for the purpose of startingthe steam in the boiler when it is desirable to do so before the Welding-furnace is set in operation, or for generating steam when at any time the `welding-furnace is not in use, or for assisting to generate steam in case or" the escaping heated gaseous products ot' combustion from the welding-furnace being insuicient for that purpose.
The boiler represented is of the cylindrical return-flue kind, havingtwoues, e e. Extending right through it in the Lipper part of the setting B there are two iues,j'f, one on each side, extending from end to end ofthe setting, the entrances to said ues being at g g, close to the end of the boiler farthest from the welding-furnace C and over the furnace D, and the exits being through a breeching, E, at the opposite end of the boiler and in communication with the return-fines c e. At the end of the boiler farthest from the welding-furnace C and over the furnace D the return-fines e e communicate with a smoke-box F, on the top of which is the chimney or stack G.
The operation of the invention is as follows: The heated gaseous products of combustion from the Welding-furnace escaping from the ue b pass, as indicated by arrows in Fig. 1, under the boiler to the openings gg, Figs. 1 and 2; thence through lthe outer ues f,f, to the breeching E at the opposite end of the boiler, whence they pass through the returnues e e to the smoke-box F, and escape by the l chimney G, having yielded up all their available heat to the boiler. When there is a fire Witnesses:
