JOHN MILNE, OF BROOKLYN, NEIV YORK.

STEAM BOILER OR GENERATOR.

SPECIFICATION forming part Of Letters Patent N0. 577,142, dated February 16, 1897.

Application filed June 12,1896. Serial No. 595,250- (No model.)

To all whom it may concern:

Be it known that I, JOHN MILNE, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Steam Boilers or Generators, of which the following is a specification.

My invention relates to certain improve holes J therein. The letter B designates the nest of steam pipes or tubes, which are inclined downwardly from the drum A to the mud-drum A and the letters 0 D designate the downwardly and upwardly inclined tubes, respectively, from the drum A to the drum A, and G designates the nest of pipes that connect the drum A with the mud-drum A The adjuncts of the boiler are substantially of ordinary form and are composed, essentially, of the framework T, grate G at a point under the higher portion of the tubes 13, fire-doors I, hangers H for supporting the drums A A, and manholes J, disposed at divers points, as may be found expedient.

From the description it will be apparent that a continuous flow of water is maintained through the medium of the tubes 13 O C, so as to subject the water to the action of the fire in the boiler continuously until the same is converted into steam with a manifest economy of heat.

In order to increase the effect of the heat upon the generating-tube B, I have arranged partition 13 parallel to the plane thereof in such a manner to cause the heat to take a circuitous course, as indicated by arrows in the drawings, and with a View of superheating the steam I have arranged above the pipes O a partition S, with perforations b for the passage of the hot-air gases therethrough.

In the operation of the boiler the water enters through the feed-pipe E, and thence flows through the nest of pipes O to the drum or cylinder A, thence through the nest of pipes O to the drum A thence through the nest of pipes B to the drum A, which latter practically forms the steam-generating chamber.

From this drum or chamber A the steam ment is, as to the pipes B, that the water has a tendency to return to the drum A and, as

to the pipes O, that the water obtains a certain pressure by gravity from the feed-pipe E to the drum A, while, as to the pipes D, the water of condensation, if anyin said pipes, is returned to the drum A.

In order to facilitate the entrance of the water into the pipe 0, I arrange the pipe E opposite to the mouth of the pipe '0 and perforate the pipe E in the direction of the pipe 0, which causes the water to be ejected into the pipe G and thereby manifestly increase the circulation of the water.

"What I claim as new, and desire to secure by Letters Patent, is

In a steam-boiler the combination with the drums A, A, A of the downwardly-inclined tubes B connecting the drum A to the drum A and the two nests of tubes 0, .D, inclined respectively downwardly and upwardly and both connecting the drum A to the drum A, the injection-pipe E arranged at the entrance of the pipes O in the drum A, the pipes 0 connecting the drum A to the drum A and the diaphragm F in the drum A intermediate of the points of connection of the pipes O, D, thereto, partitions B and perforated partition S parallel to the plane of the pipes B, O, substantially as shown and described.

JOHN MILNE.
