Patented March 27, 1906.
Application led January 30, 1905. Serial No. 243,421.
To all whom it Wea/y concern:
Be it known that I, STEPHEN HUMPHEEY HALE, a citizen of the United States,residing at St. Joseph, in the county of Buchanan and State of Missouri, have invented certain new and useful Improvements in a Combined Base-Burner Magazine Self-Feeder Steam- Boiler; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and'use the same, reference being had to the accompanying drawings, and tothe figures of reference marked thereon, which form a part of this specification.
The object of my'invention is toprovide a steam-boiler that by reason of its peculiar construction presents an unusual heatingsurface, obviates clogging by mud or other debris, economizes fuelV and labor, and that as. g I accomplish my object by the mechanism shown in the accompanying drawings, in which- -Figure'l is a vertical cross-section showing the interior construction ofthe device including the double cylinders and dome of the boiler and its fire-box, magazine, and coils; and Fig. 2 is apers ective of the water-cylinder, showing the e-passages and the partition dividing the same.
Similar numerals refer to similar parts throughoutthe several views.
1 is a circular metal jacket.
2 is a double'cylinder adapted to hold water between its outer and inner parts, the outer cylinder spaced from the jacket to permit the passage of ilame and smoke, the inner cylinder forming a fire-box and also serving as a jacket for coils.
3 is a steam-dome 4, amagazine of tubular form which sets centrally in the dome, its
base slightly below said dome to enable it to hold the coil in place, which is a part of the magazine and the upper end of which forms connection with said dome and extends around the tubular part of the magazine.
5 is a lire-box. f 6 6 represent a -7 lis a feed-door. 8 8 represent soot-doors, preferably eight. d 9 represents a combined c inker and draft oor.
10 10 represent the liues. 11 is a damper in the direct draft.
plurality 0f tubular (5011s.
12 and 13 are grates one on top the. other operated by the top one sliding back-fand forthjover the one beneath, the bottom one being vstationary only when it is turned edge- Wise for dumping cinders.
14 14 are lugs to hold grates in position, and 15 15 are shaker-bars to shake grates and dump the same by a quarter-turn sidewise of shaker-bar. y y
16 16 represent arrows showing the firepassage between the jacket and the water-` 23 a water-column, and 24 a bar for a damperregulator. j
25 indicates water in the water-cylinder, and 26 a weight on said dam er-regulator.
27 is a artition between t e water-cylinder and t e jacket, beginning below the top of the water-cylinder and above the main flue and circling thence to right and left downward and around the cylinder to the front of the furnace underneath the main fire-door, as shown in Fig. 2. This partition is adapted to carry the fire from the top of the cylinder down and around the cylinder to the front of the furnace and thence down to right and left around back and up to thev main flue 31, thereby forming base burner features of the boiler. 28 is a Hap-door over the top of the magazine. 30 is the ash-pit.
31 is the main flue, 33 a cap arourd the magazine forming a part of the flue `to direct draft, and 35 is a damper in main flue.
Coil 6 makes connection at its upper end with the steam-dome, extending thence around and below the tubular part of the magazine downward through the other coils to the fireboX, at which point it connects with the water-cylinder chamber. This coil is adapted to create circulation and prevent mud accumulating at the base of the magazine, rendering the magazine useless for heating purposes. Moreover, this combination tubular and coil magazine, having a heating-surface far greater than that of ther magazines of similar size,
secures proportionately` better results. The

other coils, excepting only that at the bottom, are the same as the magazine-coil shown inFig. l except that they are reversed,
` being larger at the bottom than at the top Jfor the purpose of retaining the direct heat inside the water-cylinder as long as possible. These coils fit on the outside of one another far enough apart to allow for combustion. The tubes of coils 6 6 are larger Where they enter the steam-dome than where they connect with the water-cylinder. It is the tubes not the coils that lessen the circumference'. The interior of these tubular coils correspond with their exterior, being small at one end and large at the other. The small end of each of these tubular coils is connected with the water-cylinder in the iire-box, while the large end of each is connected with the steamdome. My object in using a tubular coil the interior of which is smaller at one end than the other is to allow for the expansion of water and let steam pass the water up into the steam-dome, thereby creating dry steam and holding a steady water-line in the boiler.
34, as shown in Fig. 1, represents the bottom coil, which is connected at the steamdome and extends downward between the magazine-coil and the one next to it and around and around the magazine in a circle constantly widening from the magazine to the water-cylinder and connected therewith,
thereby creating a spread on the flame to make the flame spread the heat equally between the coils above it. This coil bears upward and inward from the water-cylinder for the purpose of creating a free circulation of water. This boiler is adapted for either high or low pressure steam.
What I claim, and desire to secure by Letters Patent, is-
In a steam-boiler the combination with a fire-box and magazine, of double cylinders spaced apart said space forming a waterchamber, a jacket spaced from the outer cylinder said space forming a chamber for passage of iiame and smoke from the fire-box, a steam-dome said magazine being in the center thereof, the coils with tubes of decreasing circumference from top to bottom and extending from said dome downward around said magazine and below through said iirebox into the water-cylinder, the bottom coil also connected with said dome and spread at its base above the iire-box to connection with said watern cylinder and fire-draft partition encircling the water-cylinder, substantially as shown and described.
In testimony whereof I aHix my signature in presence of two witnesses.
