EUGEN NEUMANN, 0E NEW YORK, N. Y., ASSIGNOR, BY MESNE ASSIGN- MENTS, TO CHARLES D. TYLER, OE NEWARK, NEW JERSEY.
Letters Patent No. 109,652, dated November'ZS, 1870.
IMPROVEMENT IN STEAMGENERATCRS.
The Schedule referred to in these Letters Patent and making part of the same.
I, the undersigned, EUGEN NnUMANN, of'the Acity ot' New York, State of New York, have invented-certain Improvements in Steam-Boilers, of which the following is a specification.
My invention relates to the combination of a series oi' slanting bridges or partitions, pierced with tubes of different diameters, placed in the interior of a steamboiler, by which a greatly more etlicieut steam-generating surface is obtained than iu any other foi-'m of vsteam-boilers.
Figure I represents a longitudinal section of my in vention.
Figure II represents a section through x' x', Fig. I.
.Similar letters of reference indicate corresponding parts.
This steam-boiler is constructed of two shells, C and D, one placed inside the other.
In the inner shell D is placed gthe iregrate E and fire-bridge F.
Behind the lire-bridge is placed a series of bridges or partitions, communicating with the Water between the Atwo shells, and placed in a slanting position, as represented, or more or less.
These bridges or partitions G G are perforated with a series of tubes, xa', screwed iutoor expanded into the walls of the same; aud the tubes being placed at right angles to the walls or tube-sheets R It, must naturally also come in a slant-ing position, by which means the vflame is compelled to 'go through' these tubes, and (tending upward) will strike the tubes at certain angles, thereby producing increased ei'ect, while the sediment and ashes from the combustibles will drop down to the bottom of the inner boiler-shell i l) simply .by the aid oi" the draught, and will not be deposited in the tubes, as iu ordinary horizontal multitubular steam-boilers, which require often to be cleaned.
The bridges or partitions G Gr are (as shown) curved at the bottom y y, by which means any sediment is prevented from lodging at the bottom. The curved position is also the most favorable for the circulation of the water contained iu the bridges or partitions.
This arrangement leaves also space between the bottom y y of the bridges or partitions and the bottom of the inner boiler D, by which means, and through a man-hole, m, in rear of the boiler, access can be had to every part of the interior exposed to the lire.
As represented, the first bridge or partition nearest to the tire-bridge contains tubes ot larger diameter than the second partition, and so on through any number of partitions placed in the interior boiler-shell.
rlhe diameter of the tubes should gradually diminish to the rear ot' theV boiler. The'object hereof` is, that the larger tubes in front allow the maintenance ofthe dame, and the smaller tubes in rear present a larger aggregate heating-surface, thereby consequently extraeting more fully the heat.
In the accompanying dra-wing two bridges are only represented, but any number can, of course, be employed to suit circumstances.
. Claim.
l 'What I claim as new, and desire to secure by Letters Patent, is-
lheemployment of slanting bridges or partitions, G G, iu the interior shell of a steam-boiler, perforated and stayed with tubes of different diameters,
lthrough which the flame and heat pass, while the Water surrounds them, substantially for the purpose shown and describe-(L EUGEN NEUMANN.
