JAMES PERKINS AND WILLIAM H. BURNET, OF NEWARK, NEW JERSEY.

IMPROVEMENT IN STEAM-BOILERS.

Specification forming part of Letters Patent No. 410,118,l dated September 29, 1863.

.T0 all whom it may concern:

Be it known that we, JAMEs PERKINS and WILLIAM H. BUR-NET, of the city of Newark, in the county of Essex and State of New Jersey, have invented a new and useful Improvement in SteamBoilers; and we do hereby declare that the following is a'full, elear,'and exact description of the same, reference being had to the accompanying drawings, in which- Figure l is a perspective view showing the exterior form and construction of the boiler and the manner of setting the same. Fig. 2 is a rear end view 5 and Fig. 3 is a transverse section with the asetting removed to the line X X, Fig. l.

The same letters indicate like parts in all the figures.

The nature of our invention consists in combining a tubular boiler with a cylindrical boiler in such a manner as to secure great strength, durability, and simplicity of construct-ion, and planned insuch a way as will enable it to be set so that access may readily be had to the tubes for cleaning, inspection, and repair, and the surface be so exposed to the action ot' the heat as to produce the greatest amount of steam from any given quantity of fuel. l

Ve are aware that tubular boilers have been before combined with cylindrical boilers,

the most prominent example of which is the Boardman boiler, so called, and every modication thereof, but we do not know that they have been combined in parallel line with each other, and so that they may be set in hori4 zontal position, as represented in Fig. l.

In the drawings, A is the cylindricalboiler, B is the tubular boiler, and C (l are short cylinders connecting A and B together.

His the exterior brick-work or setting ot the boiler.

L is the furnace.

M is the ash-pit, and N, Fig. l, is a door at the rear end ot1 the boiler, by means ot' which access is gained to the rear end of the tubula boiler B.

By means of the side door (seen at O, Fig. l) access is had to the front end of the tubular boiler B. F is a partition or bridge wall, of brick-work,dividin g oft'the furnaces and ashpit, and having an open space at the top K, through which the heat passes from the furnace. E is a horizontal arched partition,of iron or brick-work, extending from B to F, on aline with the top of B.

G is a continuance of the partition E, and G is a half-partition, serving also to support the rear end of B. The heat from the furnace passes through the opening K along the under side of A and the upper surfaces of E and B, thence to the rear end of B, thence downward, thence forward through the tubes of B, thence downward, thence underneath B, and thence escapes through thc chimney P, Figs. 2 and 3.

What we claim as new and of our own invention, and desire to secure by Letters Patent of the United States, is-

1. 'lhe combination of the cylindrical boiler A with the boiler B and short cylinders G C, in such a manner that the position of B is horizontal and also parallel and perpendicular to the boiler A, so that the steam generated iu B will ascend in a perpendicular line through C C to A without obstruction.

2. The combination of the tubular or other boiler B with the -horizontal partition E and extension thereof, G, substantially in the manner and for the purposes described.

3. The combination of the boiler B with its setting E, G, andG, substantially in the manner and for the purposes described.

4. The combination of the parts A, B, E, F, G, and G, substantially in the manner and for the purposes described.
