SPECIFICATION forming part of Letters Patent No. 1337,0753, dated March 2, 1886. Application filed September 17, 1885. Serial No. 177,324. (No model.)

.7 all whom, it may concern: it known that I, JOHN R. MOORE, 0 Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Steam Generators, of

which the following is a specification.

My invention relates to that class of steamgenerator in whichv the heatingsurface is composed of coils arranged within a furnace.

Important objects of the invention are to provide a generator in which steam will be made very rapidly, in which the-coils and connecting parts will be supported in a very stable manner and preferably independent of the furnace-structure, and to secure a. thorough separation of the steam and water which pass from the coils, so that drysteam will be produced.

1n the accompanying drawings, Figure 1 is a vertical section of a generator embodying myinvention. Fig. 2 is a side view of the working parts of the generator, the casing'and furnace being omitted; and Fig. 3 is a transverse section of a drum with which the upper ends of the heat-ing-coils'are connected and a portion of the frame which supports this drum.

Similar letters of reference designate corresponding parts in the several figures.

A designates the furnace, which, as reprev sented, consists of a cylindric metallic shell or casing, B, and a lining, B, of fire-bricl or other suitable material.

C designates the grate, which may be of any suitable construction.

The heating-surface of the generator is formed by a series of coils which are arranged vertically in the furnace, and of which any suitable number may be employed. I have here represented four coils, D D D Dflwhich are arranged one within another, and which are of barrel-like form, or have their convolutions gradually increasing in diameter from the middle upward and downward toward opposite ends. This gives the coils approximately the form of two cones united at their bascs,xthe lower one being inverted. 'lhese coils are to be made of pipes or tubes. I have also represented a feed-coil, D, which is of cylindric form and surrounds thedieatingcoils, it being arranged near the interior wall of the furnace.

E designates a drum arranged horizontally above the furnace-coils, and which may be of cast or wrought metal. As here represented, this drum is supported upon upright frames F, the form of which is best shown in Figs. 2 and 3. These frames may be of wroughtiron, and consist of two diverging legs united at the upper ends to form a semicircular cradle, F, wherein the drum E rests, and having their ends secured by boltsa tothe foundation of the boiler. The two legs of the frame F may be connected at their lower ends by a bolt, F, as shown'in Fig. 2, so as to prevent them from spreading.

The several coils DDD D are connected at their upper ends by branches (2 (1 d d with the under side of the drum E, each branch being connected bya coupling, d*,with a nipple fixed .in the drum. These branches (1 d, &c., serve to support the coils on their one side, and the coils are additionally supported by suspenders or hangers, e,which are hung from the drum E, and which receive the upper convolutions of each coil at a point opposite its branch d d, &c. In this waythe coils are suspended or depend .from the drum and have'their weight supported by the drum and the frames F.

Above the drum E, I have represented a steam drum, G, which is connected by branches G with the drum E, and in these branches G are vertical plates or partitions g, which have the effect of separating or dividing the water from the steam which passes upward through the branches into the steamdrurn G.

I have shown in the drum E ahorizontallyarranged partition or baffle-plate, e, which may be supported on lugs or ears 0", projecting from the inner sides of the drum. which passes upward through the branches d d, 860., when the generator is in operation, impinges against the under side of the baffleplate 6, and in this drum E the water is separated from the steam.

From opposite ends of the drum returupipes H lead downward, and are connected at their lower ends with manifolds H, from which branches f ff f lead to and connect 0 The steam roo with thelower ends of the several coils D D, 82c. These manifolds H are connected at their lower ends by a pipe, H", and this pipe is in turn connected by-a pipe, H with the 5 lower end of the feeding-coil D, the pipes H Hbeing arranged outside the furnace. From. the pipe 1-1" leads a blow-off, H, in which is a blow-off valve, 71, and in each of'the downwardly-extending returnpipes is arranged a r check-valve, h, which may beoftheordinary form, and which is placed so that it opensdownward or in a direction away from the drum E. These valves h permit the passage of water downward through the pipe H and 1 manifolds H, and prevent the passage of wa ter upward through the pipes H.

With the upper end of the is connected a feedpipe, d, the feed-pump or injector.

The generator is inclosed by a cap or top, B,'secured to the outer casing, B, and from it leads theoutlet-pipe B to a smoke-stack or chimney. The inner heating-coil, D,'fmay have stopfeeding-coil which leads from '25 pers d closing itsin'terior at the top and bottom, so that the heated products fromthefurmice A will be prevented from passing directly upward through the 'innercoll, D, and will be compelled to circulate or travel circuitouhly upward between the con'volutions of the sev- I eral coils, and will therefore, be most effective in heating them. 7 As before, stated, the arrangement of the check-valves h precludes an upward cii'cula- ,35 tion through the pipes H, and when the generator is in operation the circulation takes I place upward through all-the heatingcoils, and thence to the drum E,"which constitutes a separator to divide the water fromthe steam, 4o andthe steam passes upward into the steamdrum G, while the water'ret'urns downward through the pipes H and manifolds H, a'nd'is supplied by the branc hesff, 850., to the lower ends of the several heating-coils. yThe pipe H", which connects the manifolds H at their lower end, tends to equalize the circulation through each of the return-pipes Hand manifolds and through the'coils which are supplied through the branches from the $0- manifolds.

From the above description. it will be seen that in this improved generator the heatingsurface isveryeflbctive. The working parts are supported independent of the casing or furnace, and are therefore not liable to be strained by unequal expansion, and effective provision is afforded for separation of the water from the steam, in order to produce dry steam' and for maintaining the circulation 6o vthrough the heating-coils constantly in one direction. E

It will be seen that by means of the pipes H H and the branches ff f f the return pipes H and the lower ends'ofthe feeding and.

heating coils are all connected together.

By making the lower portions of the heat ing-coils of inverted conical form the several convolutions of each coil are brought outof li'ne vertically and are more exposed to the heat of the fire than would be the case if the coils were cylindric from end to end, even though such cylind'ric'coils-were terminated at the lower ends at different levels.

What I claim as my invention, and desire to secure by Letters Patent; is-

l. The'combination, with a furnace and 'heatingcoils arranged vertically thereon, of a horizontally-arranged drum, with which the upper ends of the coils are connected and from which the coils depend, whereby the drum is made to support the weight of the coils, up-
