Description

UNITED STATES PATENT OFFICE.
L. LEFEBVRE, OF DONALDSONVILLE, LOUISIANA.
IM PROVEM ENT IN STEAM-BOI LERS.
Specification forming part of Letters Patent No. 23,848, dated May 3, 1859.
To all whom it may concern:
Be it known that I, L. LEFEBVRE, of Donaldsonville, in the parish of Ascension and State of Louisiana, have invented a new and useful Improvement in Steam-Boilers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, forming part of this specification, in the several iigures of which similar characters of reference denote the same part.
Figure l is a perspective view of boiler and furnace. Fig. 2 is a perspective view of boiler, showing projecting ue F. Fig. 3 is a crosssection of boiler and furnace, showing eXterior flue, B, section taken on line 0 P, Fig. et. Fig. 4L is a longitudinal section of boiler and furnace.
The several parts of boiler and furnace are represented as follows:
A represents the boiler,fiuted longitudinally; B, furnace; B ue running under and around lower portion of boiler and made to conform to the fluting of the boiler; C, chimney; C', brick-work; D, ash-pit; E, door giving access to ue; F', front of boiler; F, flue running through boiler and fiuted longitudinally; a af, braces placed at intervals in boilerfor strengthening same; a c, braces in flue F for giving strength.
The nature of my invention consists in the construction of boilers by tluting both boiler and flue longitudinally and strengthening the same with hoop-braces placed at intervals, and in combining this construction of boiler With a corrugated or tluted surface of eXterior ue, whereby the products of combustion are brought into intimate connection with all parts of thefire-surface.
The uting of boiler and iue gives an increased ire-surface, kept in form and sustained by the bands a a. The undulating surface of the bottom of iiue B', conforming, as it does, with Vthe flutes of the boiler, causes the hollow portions of the hre-surface to be heated as much as the projections.
I do not claim the corrugation of boilerplates broadly considered; but
I claim- The longitudinally-tinted boiler braced as described, in combination with the conformable under surface of the exterior iiue, B,sub stantially as and for the purpose set forth.
In testimony whereof I have hereunto signed myname before two subscribing witnesses.
L. LEFEBVRE.
