EDWARD MEIER, OF PHOENIXVILLE, PENNSYLVANIA.

' STEAM-BOILER.

Application filed August 6, 1915.

To all whom it may concern:

Be it known that I, EDWARD C. MEIER, a citizen of the United States, residing at Phoenixville, in the county of Chester and State of Pennsylvania, have invented certain new and useful Improvements in Steam- Boilers, of which the following is a specification.

My invention relates to improvements in steam boilers, the object of the invention being to provide an improved construction and arrangement of separate chamber adapted to receive a pre-heater or super-heater, and control the flow of smoke and gases through said chamber, whereby the heat units may be utilized as desired.

. A further object is to provide a steam boiler of the character stated with an improved construction of partition wall, whereby a chamber may be formed by an arrangement of tile supported on the water tubes of the boiler, and which tile are self locking, preventing any. possibility of accidental displacement.

IVith these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings: Figure 1 is a view in transverse section illustrating my improvements in connection with a single unit boiler. Fig. 2 is a view in longitudinal section through the center of Fig. 1, portions of the structure being shown in elevation. Fig. 3 is an enlarged fragmentary view. showing how the bottom of the chamber is formed. Fig. 4 is a similar view showing how the side walls of the chamber are formed. Fig. 5 is a view similar to Fig. 1 illustrating how my improved chamber may be located between a pair of boiler units. Fig. 6 is a view in section on the line 6-6 of Fig. l with parts of the structure being shown in elevation.

1 represents longitudinally positioned drums supported on box headers 2 connected by water tubes 3, and constituting a well known type of steam boiler unit.

In Figs. 1 and 2, I have illustrated a single boiler unit in which a number of tubes at the center of the headers are omitted, and in place of such tubes I -.form a heating chamber 4 by my improved arrangement of tile as will be hereinafter explained. The

Specification of Letters Patent.

Patented Nov. 9, 1915.

Serial No. 43,952.

chamber 4 extends throughout the length of .the boiler unit, and the top is formed by ,in'one direction by other water tubes 3 hav ing a staggered relationship to the vertical series of tubes. In other words, the water tubes of the boiler are arranged in series with the tubes of one series having staggered relationship to the tubes of other series, and the tile 7 rest between a vertical series of tubes and are held against movement in one direction by an adjacent series of tubes as shown clearly in Fig. 4.

The tile 7 are constructed with tongue and groove interlock as shown at 8 and 9 in Fig. 4. In other words between each pair of tubes 3 of the vertical series of tubes, I 10- cate two longitudinal series of tile 7, the lower series having a curved bearing surface 10 resting on the tube 3 below and the upper series of tile having curved surfaces 11 at their upper edges bearing against the tubes 3 above. The adjacent faces of the tiles are fiat and smooth as shown at 12, and at such flat'faces the tongue and grooves 8 and 9 are provided as shown.

The tile is of such a thickness that when supported between the tubes, the outer faces of the tiles at their points of juncture will bear against adjacent water tubes 3, and prevent, any possibility of the outward movement of the tile.

As the curved faces 10 and 11 prevent any movement of the tile 7 inwardly, and the tongue and groove formations and 9 prevent any separation of the interlocking tile, the wall when once made will be permanent, and there will be "no danger of disconnection except the normal wear and tear, and tile can be replaced whenever desired.

To position the tile between the boiler tubes, the lower section 7 is first placed in position, and then the upper section is moved into position longitudinally relative to the first section.

The chamber 4 is provided at one end in its lower wall with an inlet 13, and with an outlet 14 at its top adjacent its opposite end,

The outlet 14 is controlled by dampers 15, and it is to be understood that the products of combustion will enter inlet- 13, flow through the chamber l, and escape through the outlet 14 as regulated by the dampers 15.

In the chamber 4, I locate a super-heater 16 which of course may constitute a preheater if desired, and I would have it understood that hereinafter in referring to this part 16 as a super-heater, that I intend the same to cover any form of boiler unit, either for pre-heating, super-heating, or generating steam.

In the modification illustrated in Figs. 5 and 6, the chamber +1: is located between two boiler units, but in other respects is precisely like the structure above described, and I have used the same reference numerals to indicate like parts. In this modification, I have illustrated the super-heater 16 as supported from the top, while in the form shown in Figs. 1 and 2 the super-heater is projected longitudinally in the chamber ff. It will therefore be noted that with my improved construction I am enabled to pro vide a chamber through which the products of combustion are controlled, and therefore I can heat said chamber to the desired degree for the purpose intended, and can pr0- vide such a chamber without in any way increasing the size of the boiler, but utilizing to the full extent all of the boiler space.

My improved arrangement of tile may also be utilized to form the side wall of a boiler as shown in Fig. 1, in which view it will be noted that in addition to the tile 7 and 8, I employ an outer covering of plaster 17 and sheet iron 18 to form the outer surface of the wall.

Various slight changes might be made in the general form and arrangement of parts described. without departing from my invention, and hence I do not limit myself to the precise details set forth, but consider myself liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

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

1. In combination with a boiler having water tubes therein, of vertical and h0rizontal partitions supported on the boiler tubes and forming a chamber, the vertical partitions of said chamber consisting of tile located between vertical series of tubes and bearing against the adjacent series of tubes,

substantially as described.

2. The combination with a boiler having horizontal water tubes arranged in staggered series, partitions forming a chamber, the vertical partitions of said chamber consisting of tile located between vertical. series of Water tubes, the tile between each pair of water tubes comprising upper and lower sections having tongue and groove interlock, substantially as described.

3. The combination with a boiler having horizontal water tubes arranged in staggered series, partitions forming a chamber, the vertical partitions of said chamber consisting of tile located between vertical series of. water-tubes, the tile between each pair of water tubes comprising upper and lower sections having tongue and groove interlock, said tongue and groove extending longitudinally of the tile at their meeting edges, the opposite edges of said tile curved and bearing against the vertical series of tubes, substantially as described.

4. The combination with a boiler having horizontal water tubes arranged in staggered series, partitions forming a chamber, the vertical partitions of said chamber consisting of tile located between vertical series of water tubes, the tile between each pair of water tubes comprising upper and lower sections having tongue and groove interlock, said tongue and groove extending long1tudinally of the tile at their meeting edges, the opposite edges of saidtile curved and bearing against the vertical series of tubes, and said tile at their meeting edges bearing against tubes of an adjacent series, substantially as described.

5. In a boiler, the combination with water tubes, tile supported by the water tubes and forming a chamber, a heater located in the chamber, and means for controlling the flow of smoke and gases through said chamber, substantially as described.

6. In a boiler, the combination with water tubes, tile supported by the water tubes and forming a chamber, a heater located in the chamber, said chamber having an inlet at its lower end, and an outlet at its upper end, and dampers controlling said outlet, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

EDWARD c. MEIER.
