TO ALL WHOM` IT MAY CONCERN:

Be -it known that I, ROBERT BAILEY, of Idaho City, in the county of Boise, and Territory of Idaho, have invented a new and useful Improvement in Steam Boilers; and I do hereby declare that the following is a full: clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- .Figure 1 is a side elevation of the boiler.

Figuren? is a vertical section of theboiler taken in the plane of the line :z: x, fig. 4.

Figure 3 is a horizontal section of the boiler taken in the plane of the line y y, g. 1.

Figure 4 is ahorizontal section of the boiler taken in the plane of the line z z, iig. 2.

Similar letters of reference indicate like parts.

This invention relates to improvements in a steam'boiler, and consists in constructing it in sections in such manner that it may be readily opened and taken apart forrepairing or cleaning the ire dues and spaces in the different sectional parts, which fire ilue and spaces are so divided and arranged asto present an immense amount of re surface in proportion to the size and weight of the boiler, compared with ordinary boilers. The boiler, as a whole, is very compact and strong, and although it may be advantageously used anywhere, it is particularly adapted to mining purposes in distant interior localities, where transportation is diicult and expensive, on account of its weight being comparatively small and the great portability it possesses by division into sections. My sectional boiler has two principal parts divided vertically, each principal part being also divided into two diiierent sections,

In fig. 1, A`A represent the two principal parts or sections, each ofl which is divided into two sections, BB', as shown clearly in fig. 2. The ire grate C extends under both principal sections, and between them is a vertical ire space D, over the-lire chamber E, which leadsdirectly into the exit ilue F, at the top of the boiler. The'central subdivisions or sections, B B', on each side of the re space D, have running through them a series of horizontal or nearly horizontal tubular fire dues a a a. The outside jackets or sections, B B',Imay be modified in their construction as represented in the drawings, Awherein are shown two modes of arranging the ilues and ire spaces; one of these sections being built with tubular fire ilues running through water compartments, and the other with a dat fire space or ilue between two dat water compartments, either of whichmethods of construction may be adapted in my sectional boiler. In figs. 2 3 4, b b b, are seen the tubular ire i'lues passing transversely through the water compartments e c, of one section, between which is also a larger lire space d; and in the othersection is seen the flat iire ilue e, between the water compartments And between both sections B' B', are lire spaces e' e. The two outer sections or jackets B B, are pivoted to the central sections B' B', through trun# nions at their lower ends by rods g g which pass` through the shells on each side of lthe boiler, allowing the jacket sections to be opened outward Vreadily for the purpose of repairing and cleaning the scale and ashes in the fire ilues and spaces when necessary, as'shown by fig. 1, in red. The central sections B' B' may be made with water compartments iz', extending 'outside of the jacket sections and enclosing fire spaces jj between them, as

shown in figs. 3 and 4. The grate bars c c are made hollow, with their ends opening into the central sections B' B', as shown in fig. 3, so that the water in the boiler shall circulate through them.- At the upper end of the fire space D is a damper, k, opening into the exit due F. This damper may be opened for direct draught when the fire is kindled, but for making steam it is closed, whenthe products of combustion will passindirectly to the exit flue through all the lire ilues and spaces, as indicated by the arrows, fig. 2, and thus act upon a very large extent of fire surface, and make steam very rapidly with'a small consumption of fuel. The boiler may have doors m opening into the fire chamber on both sides; the feed pipes n n connect with each section ofthe boiler, and the steam pipes s s lead from each section to a common steam pipe connected with the steam cylinder of the engine. Gauge cocks t t are placed on all the sections of the boiler.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. I claim a sectional-steam boiler divided into four principal parts, two central sections B B', and two external jackets B B, constructed, combined, and arranged as herein described.

2. I claim ,the combination of the hollow grate bars with the centralseetions B' B', and the jackets B4B,

arranged and connected as herein described.

3.' I claim the damper c, for giving direct or indirect draught through the boiler, in combination with the fire spaces D and e e', and the exit ilue F, arranged and operating as and for the purposes herein described. ROBERT BAILEY..
