Application filed November 23, 1899. Serial No. 737,993. (No model.)

To to wit/07m it may concern:

Be it known that 1, ROBERT RAMSDEN, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Steam or Gas Generators, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

The object of my invention is to provide an apparatus by means of which liquids may be generated rapidly and at slight expense into steam or other gas. I

Speaking generally, my invention consists in the following improvements: first, the form of the generator or boiler and the means for introducing the liquid into the generator, where it is to be formed into steam or gas; second, in the material which is placed in r the incoming passages and the interior of the partially in section, of the generator or boiler and its inolosing case.

The boiler consists, essentially, of the shell A, provided on two sides with the projecting rib A and on two other sides with projecting cones A The wall of this boiler is made of sufficient thickness to allow the proper amount of heat to be absorbed and retained, and the purpose of the projections and cones, which, as shown in 'the drawings, are staggered, is to cause the heat, which is produced from a suitable source of supply, to circulate around the surface or shell A in order to properly heat the same. Through the two sides of the shell of this boiler are formed passages D and D, the passage D opening at the bottom into a transverse passage E, while the passage D opens into a transverse passage E, these two passages E and E crossing each other, as shown in Fig. 3. From these passages E and E extend vertical passages F, opening into the interior of the boiler or generator. The ends of the passages E and E are closed by means of caps or plugs K.

D is a pipe connected with the source of liquid-supply and the passage D. D is also a pipe connected with thesource of liquidsupply and the passage D. The liquid to be generated into steam or gas is fed in any desired manner through the pipes D and D With the apparatus so far described it will be seen that theincomin g liquid is distributed into the interior of the boiler or generator at a plurality of points, and, moreover, is so distributed in a somewhat comminnted form and is brought to a considerable heat, if not to vapor, before it reaches the interior of the boiler, being subject to heat in its passage through the passages D D E E. In order to provide for still further comminution of the liquid in its passage through these passages, I fill the passages with a material which is new with me for this purpose and which produces very advantageous results. This material which I use is metal gauze or wire meshing, preferably of copper, although I have used iron with good results. Either in addition to this or as a substitute I use carborundum in a granular or finely-divided condition. The preferable manner is to use alternate layers of the'wire mesh or gauze and carborundum, the wire mesh being pressed into close continuity. These materials I have found highly efficient. The carborundum is practically infusible, non-oxidizable, and insoluble, except under extraordinary conditions, and therefore always presents a multitude of heating-surfaces to act on the liquid in its passage. The same is true of the wire mesh in that it presents a multitude of surfaces to act upon the liquid and while pos sibly oxidizable it is impossible to oxidize it carborundum H, although the interior of the boiler, like the pipes, may be filled entirely with carborundum or with the wire mesh.

0 represents the outlet for the gas or steam.

B is the cover for the top of the boiler, and J represents an asbestos covering which may be placed around the side and top of the boiler. This is done by providing a hollow sheet-iron casing I, around which the asbestos is packed the casing I contacting closely at the sides with the projections from the boiler, but leaving a space at the top.

I is a pipe or tube to carry off the products of combustion after having passed around the boiler or generator.

If desired, the boiler may be divided into compartments, as shown in the drawings, by means of the cross-walls A. This is valuable, especially in large-sized generators, to enable the heat of the walls A to be distributed throughout the whole space of the interior of the generator.

The operation is as follows: The liquid to be generated into gas or steam is' fed in proper manner into the pipes D and D through which it passes to the passages D D, respectively, thence to'the passages E E, and thence through the passages F into the interior of the boiler, up which it passes and escapes as steam or gas through the tube 0. As may be seen, from the very point of its entrance into the passages D D until its exit at the pipe 0 the liquid is comminuted both by the material in the passages D D andE E, the plurality of passages F, and the material in the interior of the boiler. At the same'time it is subjected to the heat absorbed by the boiler from the products of combustion-from the time of its entrance into the passages D and D until it passes out of the pipe 0. By this construction the liquid is not only subjected to heat during its-entire passage and for a considerable period of time, but is subjected to this heat throughout its wholetime in a finely-comminuted condition.

-Of .course I'do not intend to limit my invention, except wherein the same is specifically claimed, to the use of carborundum or wire mesh in the passages D D, as one part of my invention consists in the construction of passages for delivering the liquid into the interior of the boiler and subjecting it to heat duringsuch delivery; nor do I intend to limit myself to the use of alternate layers of carborundum and wire mesh, as my improvement is applicable to a construction in which either carborundum or wire mesh alone is used, the use of both in alternate layers having, however, certain advantages.

Having now fully described my invention, what I claim, and desire to protect by Letters Patent, is-
