SPECIFICATION forming part of Letters Patent No. 747,207, dated December 15, 1903.

Application filed November 10,1902. Serial No. 130,691. (No model.)

To (ti/Z whom it may concern:

Be it known that LOLIVER N.MOB.IN, a citizen of the United States of America, and a resident of Holyoke, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Boiler-Furnaces, of which the following is a full, clear, and exact description.

This invention relates to improvements in i0 boiler-furnaces, and has for its object the provision of means whereby the Walls of the furnace-chamber will not become obstructed by accumulations resulting from the intense heat which causes clinkers to adhere to the side walls of the fire-chamber. In order to prevent the formation of clihkers on the side walls of the fire-chamber, I provide pipes through which water may circulate, these pipes being located and embedded within the I wall of the fire-chamber and connected with the boiler. I furthermore provide suitable regulating-cocks in conjunction with the circulation-pipes, all substantially as will hereinafter fully appear, and be set forth in the claims.

In the accompanying drawings a manner of carrying out this invention is illustrated.

Figure 1 is a front elevation of the furnace for the boiler, partially in section for more 0 clearly showing the novel parts and the arrangement thereof. Fig. 2 is a longitudinal sectional view through the apparatus. Fig. 3 represents a front view of the boiler and illustrates a hot-water system operated directly from the circulation-pipes above referred to.

In the drawings,10 represents the fire-chamber of the furnace for the boiler 12, 13 indicating the bridge-Wall. I build in any suitable manner along or within the side walls 14 of the furnace feed-pipes 15 15, having at their front ends couplings 16 16, with which are connected upright pipe extensions 17 17, these extensions 17 being united by the coup- 5 lings 18 with the horizontal pipe 19, which has by the branch 20 a connection with the lower portion of the boiler to receive from the latter a supply of water for circulation through the system of piping of which the pipes pointed out are a part. The said pipes 15 15, extending along Within the thickness of the side Walls of the furnace, have at their rear ends, which are located within the body of the bridge-wall 13, connections 15 with the pipes 22, which traverse along the front of the bridge-wall one above the other and have connections with the upper and lower longitudinal pipes 23 23, which are built into or embedded in the side walls of the furnacechamber. At their forward ends these pairs of pipes are respectively connected with the vertical pipes 24, which are joined by a crosspipe 25, from which the branch 26 enters the boiler at an upper portion thereof.

It will be understood that the water from the boiler passing from the lower portion thereof into the feed-pipes 15 15 Will thereafter be forced or pass through the pipe-sections 22 22 and 23 23 at the forward face of the bridge-wall and in the side Walls of the fire-chamber, resulting in keeping the furnace-walls at a materially lower temperature than would be the case in the absence of these pipes, and the water thus enters the boiler at an upper portion thereof in a highly-heated condition.

Cocks 27 are provided between the supplypipes 15 of the boiler and the feed-pipe 20, these being advantageously comprised in the couplings at 18, and cocks or valves 28 pro vided inthe return-pipes 24. Furthermore, blow-off cocks 30 and 32 are provided at the bottom of the pipes 17 and 24, below the connections therewith of the longitudinal pipes 23 and at the junction of the feed-pipes 15 with the branches 17,Which connect them With the boiler, respectively.

Originally the blow-0E cocks are shut and the cooks or valves 27 and 28 leftopen; but by leaving open the valves 27, shutting the valves 28, and opening the blow-off cocks 30 the circulation-pipes may be cleared by blowing Water therethrough from. the boiler, and out through the said blow-off cocks 30, or by closing the valves 27, opening the valves 28, and opening the blow-off cocks 32- the system may be cleared by blowing steam therethrough, which will escape at the said blow-ofi cocks 32.

From the above description it will be un- Ico derstood that the pipes 24 constitute portions of a pipe system which is located outside of the boiler and which connects the Water-space of the latter with the steam-space. Hence it will be seen that the water-level in the pipes 24 will be substantially uniform with that inside the boiler. In view of this fact my invention comprises a hot-water system in connection with the circulation system above described, this hot-water system being applicable in supplying hot water to various places in the building, as is, for instance, shown in Fig. 3. Here a pipe 40 is illustrated in direct connection with the return-pipe 24, but at a point below the waterlevel in the boiler and preferably below the valve 28, so that even if the latter should be closed the pipe 40 will always be full of water. This pipe 40 may have any suitable number of branches 41, leadingto different floors or rooms, when hot water may be drawn from faucets 42 into sinks, tubs, or similar appliances 43, as will be readily understood.

Fresh water may be introduced into the boiler through a main supply-pipe 44, having a gate or similar valve 45 and connected with the pipe 19, as shown in Fig. 3, the valve 45 permitting the water to be shut off when the supplyin the boiler is sufficient or when the latter is to be blown out.

A valve 46 is provided in the pipe 19 between the pipe 20 and the main supply 44, so that when the gate '45 is open the direct passageof waterintothe boiler through the pipe 20 may be interrupted, and the fresh Water may therefore be conducted through the pipe 17 and thence through the circulating- pipes 15, 22, and 23, in this manner efficiently cooling the walls of the fire-box and at the same time itself becoming heated. It is of course evident that the left side of the boiler may be similarly supplied with a supply-pipe, as the right, or that the valve 46 may be disposed in the pipe connection 20, in which case the circulating-pipes on both sides of the fire-box would receive a fresh water-supply simultaneously.

Having thus described my invention,what I claim, and desire to secure by Letters Patout, is

1. The combination with a boiler and the boiler-furnace, of feed-pipes having connection with the boiler and extending along, and embedded within, the side walls of the furnace,and extended transversely of the bridgewall, one or more pipes located in the inner side of the bridge-wall, with which said feed pipes are connected, and pipes connected with the bridge-wall pipes, embedded within, and extended along the inner sides of the furnacechamber and having return connections with the boiler, substantially as and for the purpose set forth.
