AVARD S. EMERY, OF NEWV YORK, N. Y.; FRANCES O. EMERY ADMINISTRA- TRIX OF SAID AVARD S. EMERY, DECEASED.
. STEAM-BOILER- a SPECIFICATION forming part of Letters Patent No. 425,766, dated April 15, 1890.
Application filed April 2, 1888. Renewed February 1' 1 9 $Brial1 1 (N0 111M191) To all whom, it may concern.- of the inner shell or case 2,'and through these Be it known that l, AVARD S.

Fig. 2 is a plan tight by jam-nuts above and below the top 25 of the lower water-chamber. Fig. 3 is a plan 4., and it will be apparent that by these pipes of the second water-chamber; Fig. 4, of the B and B the range of water-chambers is susthird, and Fig. 5 of the fourth,Water-chamber. pended from the top of the inner case, and it The boiler is preferably cylindrical, and is free to expand and contract, according to composed of an outer casing 1 and inner cats the temperature to which it is exposed.

The doors for this same place the water of condensation is these openings are of any ordinary or desired returned to this boiler or heater, and it passes 4 character, and I prefer to allow the products not only into the water-leg between the cases 0 of combustion to pass out through the verti- 1 and 2, but it also ascends through the pipe cal fiue 6 at the top of the boiler.

Thenumber,however,may and B to the water-space at the top of the 45 be more or less.- Each water-chamber is prefboiler, and should therebeanydifference in the erably circular and the top and bottom thereof expansion or contraction of the cases 1 and 2 slightly conical, and these are usually of castand the water-chambers A and pipes B the iron and of such a size that the products of horizontal portion of the pipe R will spring combustion are free to pass between the outer and allow for this variation without either of 5 edges of the water-chambers and the interior the joints being injured or made to leak, and I00 I place around the pipe R at the opening 12 a plate or septum 13, that prevents the escape of gas at this point; but it does not interfere with the slight movements of the parts due to expansion and contraction.
The top of the upper water-chamber A may be provided with avertical pipe 0 within the flue-space 6, with lateral branches S into the steam-space of the boiler, so that any bubbles of steam from the water-chambers A may ascend directly into the steam-space of the boiler and not interfere with the circulation of the water.
I claim as my invention- 1. The combination, in a heating-boiler, of" the cases 1 and 2, connected at their lower tially as set forth.
2. The combination, with a boiler having the cases 1 and 2, with the water space or leg between them, of a vertical range of horizontal water-chambers'each water-chamber having vertical flue-openings passing through the same, and the pipes B, secured into the respective water-chambers and connecting them together, and the horizontal pipe R, connecting the bottom of the lower water-chamber with the shell of theboiler, substantially. as set forth. 4
3. The combination, with the boiler-shells 1 and 2, of a vertical range of Water-chambers, each of which has passing through the same vertical flue-pipes, and the pipes B, connecting one water-chamber with the next, the pipes B, connecting the upper water-chamber-with the innershell of the boiler, and the pipe 0 and branches S within the flue 6 of the boiler and opening into the steam-space of the same, substantially as set forth.
Signed by me this 24th day of March, 1888.
