eolLER-l SPECIFICATION forming part of Letters Patent No. 627,754, dated June 27, 1899.
Application iiled July 9, 1898. Serial No. 685,537. (No model.)
To all whom it may concern:
Be it known-that I, ERNEST N. JANsoN, of Washington, in the District of Columbia, have invented certain new and useful Iml provements in Steam-Boilers, of which the folbustion between said tubes before the uptakes are reached, in that manner enabling the boiler to be worked under a considerably-` higher air-pressure than other straight-tube boilers. A greater heating-surfaceis also obtained by this arrangement within the same space or cubical contents. The gasesof combustion are forced vto travel over the tubes during a greater length of time, as it is supposed said gases will circulate lengthwise with the tubes instead of going vertically straight up. Besides the features mentioned the arrangement as a whole providesfor a boiler with a much-increased water-reserve and a greater steam-liberating surface. Unlike the majority of water-tube boilers, there are no so-called water-drums, greatly simplifying the construction, with considerable saving in weight. Eliminating water-drums renders a free and more direct circulationvfor the Water and steam. Y Owing to the manner in which the outside downflow-pipes connect with eachheader, and being removed from the influence of the furnace heat, a positive downiiow from the drums to each header independently is obtained.
Generally stated, my invention consists in the combination of vtwo steam-generators, of which each is composed of separate headers connecting opposite ends of the tubes and a drum containing Steam and water. All upper headers connect direct to the drums by means of short tubes or pipes, while the lower headers, each through an independent pipe, connect with the drum of the opposite steamgenerator, thus combining the component parts of each steam-generator into one aggregate steam-generator. The tubes of each ele.
ment in each boiler pass each other in vertical parallel planes and form equal angles with the horizontal line, varying with the length of tubes and distance between the drums. in order to form a place of substantial support for the different parts in the construction.
In the accompanying drawings, Figurelis a vertical longitudinal section through about the center of the boiler, and Fig. II is a partsectional view of Eig. I at a line X X and a part-full view showing the outside of the boiler with the casing removed. In this view some 'of the downtlow-pipes 4 4 and several,
of the tube-caps lO on the headers are removed. A.
. In the drawings, l l' represent water-tubes which are secured in an efficient manner to vthe headers 2 2. -Each header is provided with hand-holes 14 opposite the tubes,through which the tubes may be cleaned or renewed. Over each hand-hole is fastened a cap 10, the detail of which is shown in Figs. III, IV, and V. Each of the upper headers 2 2 connects to the drums 5 5 through the short tubes 3 3. These tubes are extendedto someplace above the water-level in the drums in order to discharge the mixture of water and steam above said level, as well as from the feed-water, which is supplied at the bottom of each drum. Furthermore, by this construction the upward circulation in the water-tubes is greatly enhanced, due to the dilere'nce in pressure caused by the difference in the head of water at the downiiow-pipes 4 4 and at the discharge pipes 3 3. Each lower header isl joined to the drum of the opposite boiler through pipes 4 4', either as shown in Figs. I and II or with these pipes connecting to the lower ends of the headers or'simply as shown in Fig. V. At each end of the drums 5 5 is placed a pipe l1, the principal purpose of which is to constitute a tie or brace, but also to connect the steam-space between and of the drums in each individual steam-generator.
The horizontal .tubes (marked 6) represent air-heating tubes and serve to more thoroughly abstract the heat from the escaping gases to be absorbed by the air going through The headers are beveled, as shown,
Ico
` said tubes.

The air enters the tubes at the trunk 7, into which air is forced, and after having passed through the tubes is delivered to the furnace through another air-trunk, (marked 13.) A casing 12 incloses the boiler proper.
A represents the combustion-chamber, B the grate-bars, and C the ash-pit.
E is some refractory material, and D represents the nre-doors.
F is the uptake, and G the ash-pan.
The openings 8 may be made smaller or larger by adding to or taking out portions of the baiiier shown on top.
In the process of combustion the products of gases enter the spaces V and then grad ually turn into the spaces left between the tubes in a Vertical direction, after which they ascend diagonally with the tubes, discharginginto spaces V above the tubes and through openings S-among the heater-tubes 6 to the uptake F. The Water circulates from the lower headers 2 2, through pipes or tubes 1 1', to the upper headers 2 2', and thence through the short tube connections 3 3 into the drums 5 5',and from the drum of each steam-generator, by means of pipes 4 4', back to the lower headers of the opposite steam generator. Thus the Water precipitating from drum 5 enters at drum 5 in form of steam, and vice Versa. A systematic and thorough circulation of water and steam within the boiler as a whole is consequently obtained.
Fig. V shows a modification of the lower headers and the manner in which the downiioW-pipes 4 4 are attached to said headers.
This modification consists in extending the sides of these headers sufficiently outward to allow for an additional fiat surface to be made on top of said headers. Through this extension a hole is made to take the lower end of the downtlow-pipes 4 4 insteadv of having said pipes entering the front of the headers, as shown in Figs. I and II. This arrangement permits of expanding the joint and also enables all of the Water-tubes. 1 l to be removed from either side of the boiler Without disturbing the downiiow-tubes 4 4.
What I claim as my invention, and desire to secure by Letters Patent, is-
1. In an aggregate steam-generator, the
Vcombination of two steam-generators, each composed of a steam-drum, water-tubes and single headers arranged in elements, with separate doWnfiow-pipes on the outer sides, uniting each lower header of each element in each steam-generator, with the drum of the opposite steam-generator in a manner shown and described and for the purpose set forth.
2. In an aggregate steam-generator, the combination of two steam-generators, each composed of a steam-drum, water-tubes and single headers arranged in elements, with separate downiioW-pipes on the outer sides, air-heating tubes placed above the Watertubes and between the steam-drum of each steam-generator, substantially as shown and described and for the purpose set forth.
