BOILER FURNACE.
No. 354,754. Patented Dec. 21,1886.
U ITED STATES PATENT ()FFICE.
MIGIAH WALKER, OF PORT HURON, MICHIGAN.
BOILER-FURNACE.
SPECIFICATION forming part of Letters Patent No. 354,754, dated December 21, 1886.
Application filed October 14, 1886. Serial No. 216,189. (No model.)
To all whom it may concern:
Be it known that I, MIGIAH WALKER, of Port Huron,in the county of St. Clair and State of Michigan, have invented new and useful Improvements in Boiler-Furnaces; and I do hereby declare that the following is afull, clear, and exact description thereof, reference being bad to the accompanying drawing, which forms a part of this specification.
This invention relates to certain new and useful improvements in boiler-furnaces, whereby all danger of leakage at the point of connection between the boiler and its setting is prevented.
In setting boilers in brick it is'usual to run the walls up to a point at or about the top of the dues in the boiler, and then draw in the brick-work until it meets the boiler. Now, as the boiler when put into operation expands through heat, it expands and crowds the brickwork away from it. In cooling off, the boiler contracts and draws away from the brickwork, thereby leaving a space between the wall and the boiler, which allows cold air to be drawn in, thereby tending to cool the boiler at that point.
My object in the present invention is to provide means by which there will always be a close connection at this oint to the exclusion of the cold air, thereby effecting a large saving in fuel.
In the accompanying drawing my improvement is shown in a cross-section of a boiler and its setting, and therein A represents the portion inserted between the bricks of the wall, with its projecting end bent downward in the form of a V-shapcd spring, as shown, so that its free edge rests against the side .of the boiler. Now, this spring portion of the sheet metal will give and take with the expansion and contraction of the boiler. To prevent the escape of heat at this point, I preferably fill the interior of the Vshaped spring with asbestus, mineral wool, or other non-conducting substance that will not interfere with the action of the spring itself.
-VVhat I claim as my invention is 1-. In combination with a boiler and its for mace-setting, a spring-support interposed between" the two and secured in the wall of the furnace, substantially as and for the purpose described.
2. A spring-support interposed between a boiler and the side wall of the furnace and secured to the latter, in combination with afilling of non-conducting material, substantially as specified.
