Specification of Letters Patent.

Patented Aug. 15, 1905.

novel features of construction, combination,

and arrangement of parts hereinafter described and claimed.

One object of my invention is to provide a steam or hot-water boiler furnace of the water-tube type which will be of a very compact and durable construction and which will be economical in operation.

A further object of my invention is to simplify and improve the construction and oper ation of heaters of this character, and thereby render them more eflicient and durable in use and less expensive to manufacture.

The above and other objects, which will appear as the nature of my invention is better understood, are accomplished by the construction illustrated in the accompanying drawings, in which Figure 1 is a vertical sectional view through a water-tube-boiler furnace constructed in accordance with my invention. Fig. 2 is a horizontal sectional view taken on the line 2 2 in Fig. 1. Fig. 3 is a side elevation, on an enlarged scale, of the boiler removed from the furnace; and Fig. 4 is a detail transverse sectional view through one of the water-tubes.

Referring to the drawings by numeral, 1 denotes my improved water-tube boiler, which comprises a vertically disposed cylindrical shell or body 2, which has upon its upper and lower ends reducing caps or connections 3 and 4. To the connection 3 is attached the usual outlet or supply pipe 5, and to the cap 4: is attached the inlet or return pipe 6. Said pipe 6 is attached to or formed integral with a vertically-disposed distributing tube or shell 7 which is cylindrical in form and disposed concentric with the boiler-shell 2. Said tube 7 has its upper end terminating a short distance below the upper end of the boiler-shell 2 and closed by a cap 8, and arranged in vertical and transverse or horizontal rows upon the main or body portion of said tube 7 are small openings or perforations 9. These perforations 9 aline or register with the open inner ends of water-tubes 10, which projectlaterally and radially from the cylindrical shell 2. These water-tubes 10 are arranged in vertical and horizontal rows and are placed in a staggered relation, as shown in Figs. 2and 3 of the drawings. Their outer ends are closed by caps 11. Their inner open ends may be secured in the shell 2 in any desired manner. In each of said tubes 10 is a longitudinallyextending partition-plate 12, which is substantially S-shaped in form, as shown in Fig. 1 of the drawings. These partition-plates do not extend quite to the outerends of thetubes 10, so that a circulation is caused through said tubes, as will be readily understood.

The boiler may be mounted in a furnacecasing of any desired form and in which any desired fuel may be burned; but I preferably inclose it in a cylindrical jacket or casing 15 and provide within the same and beneath the boiler a gas-burner 16. The burner 16 may be of any form or construction, and the casing 15 may be of any size and shape. As shown, said casing comprises a cylindrical body portion 17, which is closed by and is mounted to revolve between top and bottom plates 18 and 19, the latter of which is secured upon a base 20 and the former of which is provided with an outlet-pipe or connection 21 for the smoke, gases, and other products of combustion. The connection between the cylindrical body or jacket 17 and the top and bottom plates 18 and 19 is preferably effected by forming said. plates with parallel annular flanges 12 1, between which the top and bottom edges of the body or jacket 17 are adapted to slide to permit the latter to be rotated, so as to bring the opening 25, formed in the same, in line with any row of the pipes or tubes 10 to permit them to be readily cleaned or repaired. The opening 25 is closed by a suitable hinged door 26, as shown.

If desired, I may surround the furnace jacket 15 with a hot-air jacket or casing 22, which, as shown, is formed of sheet metal. A suitable cold-air inlet-pipe 23 is provided at the lower end of this hot-air casing, and one or more hot-air outlet-pipes 24:, which may lead in any direction, are provided adjacent to its upper end. it will be seen that I have a combined hot-air and hot-water or steam furnace.

The operation and advantages of my invention will be readilyunderstood from the foregoing description, taken in connection with the accompanying drawings. It will be seen that the cold water returning through the pipe 6 will be distributed by the perforated tube 7 equally to the various water-tubes l0 and in circulating through them will become thoroughly heated and will pass up through the supply-pipe 5. The boiler may .be used either as a steam-boiler or as a hot-water boiler and for domestic or other purposes, as will be readily understood.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

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

l. A boiler of the class described, comprising an upright container having water-tubes projecting radially therefrom, a flow-pipe leading from the upper end of the container, and a return-pipe entering the lower end of the container and terminating in a perforated By providing this casing 22 l distributer disposed Within the container and closed at its upper end.

2. A water-tube boiler comprising an upright watercontainer, a plurality of watertubes projecting laterally from said container, a distributer-shell in said container having perforations in alinement with the inner ends of said water-tubes, an outlet or supply pipe at the upper end of said container and an inlet or returnpipe connected to the lower end of said distributer-shell.

3. A furnace comprising an upright cylindrical boiler-shaft having outlet and inlet connections at its upper and lower ends, watertubes projecting laterally and radially from said boiler-shaft, a revolubly-mounted furnace-jacket surrounding and inclosing said boiler-shaft and said watertubes, a burner in said furnace-jacket and a hot-air casing surrounding said furnace-jacket and provided with air inlet and outlet connections, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnc-sses.
