M. S. BRINGIER, OF NEIV ORLEANS, LOUISIANA.

IMPROVED STEAM-BOILER.

Specication forming part of Letters Patent No. 25,802, dated October 18, 1859.

To @ZZ whom, t may concern.-

lSe it known that I, M. S. BRINGIER, of the city of New Orleans, parish of Orleans, and State of Louisiana, have invented a new and usefullmproved Steam-Boiler; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, similar letters of reference indicating like parts in all the figures.

Figure l is a longitudinal vertical section; Fig. 2, a side elevation; Fig. 3, a plan or top view; Fig. et, an end view of cross-section at line indicated at G G.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

A A are two cylindrical chambers or short boilers made in the usual form of cylinderboilers; B B, a series or quantity of horizontal tubes or pipes connecting the two cylindrical chambers A A together at the lower portion of their opposite heads; C, a cylinder of Inuch larger capacity, having an area about equal to the sum of the area of the tubes on the lower portion. This connects the upper portion of` the cylindrical chambers together at their opposite heads over the tubes, the top of this cylinder being level with the top of the said chambers A A.

rlhe advantages of this form of boiler over any other now in use are, first, its perfect applicability for all purposes of high or low pressure steam .with as much safety as an ordinary cylinder-boiler; secondly, exposing more effective heating-surface to the action of the fire than any internal tubular boiler of equal surface, and at the same time a much more perfect combustion of fuel can be obtained under the boiler than can possibly be done or obtained in an ordinarytubular or locomotive boiler, where the lia-me is at once, on leaving the fuel, forced into a number of small tubes before a proper or perfectmixture of the combustible gases can have taken place, hence causing a large loss of heatingsurface from the deposits of unconsumed carbon in the interior of the tubes.

The cylindrical chambers A A render this application of tubes B B B B perfectly safe, as they act as water and steam reservoirs. A sufficient amount of water can be held in this form of boiler to rcnderit very easily attended to, and a perfect equilibrium is maintained in the two chambers A A. by the large connecting-cylinder O.

That- I claim as my invention, and desire to secure by Let-ters Patent, in the above-described boiler for generating steam, is-

The arrangement of a series of horizontal tubes or pipes connecting two cylindrical chambers or reservoirs of waterand steam, in combination with the steam-cylinder C, connecting the same chambers, substantially as described.
