STEAM-BOILER.

SPECIFICATION forming part of Letters Patent No. 485,299, dated November 1, 1892.

Application filed July 29, 1892- Serial No, 441,575. (No model.)

To all whom it may concern:

Be it known that I, EDWIN REYNOLDS, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Steam Boilers, of which the following is a specification.

My invention relates to steam-boilers, and has reference more particularly to that class of boilers known as water-tube boilers.

I11 the drawings, Figure l is a vertical longitudinal sectional view of my improved boiler; Fig 2, ahorizontal sectional view of the same; Fig. 3, a front end view; Fig. 4, a vertlcal transverse sectional view on the line 00 0c, and Figs. 5, 6, and 7 are views illustrating certain details hereinafter more particularly described.

The boiler-shell A is substantially elliptical or oval in cross-section-that is to say, it is semi-cylindrical at its upper and lower portions, while its intermediate side walls are flattened, as clearly shown in Figs. 3 and 4:.

B indicates a rectangular flue extending from the fire-box or conducting-chamber C to the smoke-box D at the forward end. This rectangular flue B is provided with a series of upright water-tubes E, as shown in Figs. 1, 2, and 4.

F indicates a diaphragm or plate below the rectangular flue and at a short distance from the forward or front end of the latter, and into the space between this diaphragm and the 'front wall of the boiler the feed-water pipe G enters. From this construction it will be seen that the feed-water enters this compartment or chamber H at the forward end of the boiler and passes upward through the watertubes Where the temperature of the gases is the lowest, thus forming an ecouomizer within the boiler. By using this diaphragm F in connection with the upright tubes I cause the water to pass upward through the latter to the top of the flue B, instead of taking the shorter diagonal course, as occurs where horizontal fire-tubes are employed. Upon reference to Figs. 1, 2, and 4 it will be seen that there are two pipes I, which rest upon the bottom wall or plate of the rectangular flue, in the corners of the latter.

are closed at the rear end and project out be yond the front of the boiler at the opposite These pipes I I end, where they are each provided with a haudle or lever J, as shown in Figs. 1 and 3.

K K indicate pipes extending from the steam-dome to a point between the smoke-box, where they are provided with or secured to a valve shell or casing L, which is shown in detail in Figs. 6 and 7. This shell or casing is provided with two valve-seats ozv and b to receive the valve-rings c and d, affixed to the pipes or tubes I, the valve-seam being formed upon the inner end of the removable plug 9, as clearly shown in Fig. 7. By removing the plug c the pipe I, with its valves cand d, may be withdrawn if it should for any reason become desirable so to do. The pipes I are provided at a point between the valves 0 and d with a series of holes or openings f, through which the steam entering the shell or casing L may find its way into the interior of the pipe. The steam that is admitted into the interior of the pipes I is discharged therefrom through suitable holes or openings 9, which, as shown in Fig. 2, are arranged opposite the spaces between the water-tubes E.

When it is desired to remove the soot or deposit from the outer surface of the watertubes, it is only necessary to open the valves h in the pipe K and allow the steam to enter from said pipes K into the pipes l, the steam emitted from the pipes I being thrown, of course, from opposite sides of the boiler over the exposed surfaces of the water-tubes. By taking hold of the handles or levers J the pipes I may be turned or rotated axially, so as to insure the distribution of the steam upon the entire surface of the water-tubes.

It will be observed from the foregoing description that it is not necessary to open any part of the boiler to eifect this cleansing of the water-tubes, which is carried on with the aid of the draft, the particles detached by the steam being carried by said draft into the forward compartment or smoke-chamber of the boiler. It will also be observed that no rubber hose or similar attachments are required and no opening of doors for the purpose of cleaning, which would obviously admit cold air and deaden the draft, besides lowering the steam-pressure and blowing more or less of the soot and ashes out into the fireroom.

While I have shown the boiler as provided right diaphragm or plate beneath the flue,

serving to direct the feed-water up through the upright tubes, all substantially as shown and described.

2. In combination with boiler-shell A, flue B, and tubes E, the fixed casing L, provided with a steam-inlet pipe K, and the perforated pipe I, journaled-in the shell or casing L and having perforations f within the casing, all substantially as shown and'described.

3. In combination with shell of easing L, having a steam-inlet pipe K, and the valveseats a and b, the oscillating pipe I, provided with the valves or valve-rings c and d.

4:- In eombination with shell or casing. L, provided with a steam-supply pipe K, and with the valve-seat b, the removable plug 6, provided with the valve-seat c, and the perforated oscillating pipe I, provided with valves or valve-rings c and d.

In witness whereof I hereunto set my hand in the presence of two Witnesses.
