l UNITED STATES PATENT OFFICE;
ROBERT MAR EN SPENCER, or WAYCROSS, GEORGIA.
Application filed July 20,
This invention is designed to effect a perfect combustion of the fuel in the fire box. whereby waste of heat and fuel will be reduced to a minimum and the consumption of the smoke effected before it'leaves the fire box; and it consists in certain novel features of the structure that will be fully hereinafter described 'and particularly claimed.
In 'thedrawingsz- I Figure 1 represents a vertical sectional view of the fire box of a boiler furnace,
Fig. 2 is a transverse sectional view thereof, and
Fig. 3 is an end elevation of one of the forward end hollow blocks.
Referring to the drawing in detail, it will be seen that the numeral 5 designates the fire box of the boiler which is provided with the usual door 6, and from whose forward end extend the usual fire flues 7 through which the products of combustion pass on their way to the smoke stack.
In the bottom of the fire box, is a grate (not shown), which may be of any preferred or desirable construction. Arranged entirely within the fire box between the grate and'the fire fines are a plurality of rods 8 forming an arch support. The arch is formed in three sections which are similar in construction and, therefore, only one structure will be described in detail.
Each section includes a forward end hollow block 9 which has one end open at 10 The interme diate hollow blocks 12 have both ends opened or closed at their sides and tops, and bot- The'rear end block 14 has its ends open and its rear end is beveled as is indicated at 15, and is disposed in spaced relation to the rear wall of the fire box.
In operation, it will be observed, all of the smoke and gases of combustion are 'compelled to pass to the forward end of the fire box and then up through the fines formed by the arch sections before entering the fire flues. The gas, which is preferably forced in under pressure, entering the flue from the FIRE BOX FOR BOILERS.
.0; RussuEn forward end of the arched sections, is heated while passing through the arch, thereby con-- suming the smoke and gases.
It is to be noted that this arch structure I may be made very cheaply and yet strong and durable. The device is exceedingly sim ple, yet eflioient and reliable. embodiment of the invention has been disclosed in detail because in actual practice it attains the features of advantage enumer- The present T ated as desirable in the statement of the in- 1. In combinationwith a boiler fire box longitudinally extending rods between the vfire containing portion of the fire box and the fire fiues thereof, a plurality of arch sections of hollow construction mounted on said rods, each section including a plurality of blocks, the intermediate blocks being h0llow and open ended, and the front block hav ing one open end adjacent the next intermediate block and an open bottom. and the other end block having open ends one of which is beveled.
2. In combination with aboiler fire box.
longitudinally extending rods between the fire containing portion of the fire box and the fire flues thereof, a plurality of arch sections of hollow construction mounted on said rods, each section includinga plurality of blocks, the intermediate blocks being hollow and open ended, and the front block having one open end adjacent the next intermediate block and an open bottom, and-the other end block having open ends one of which is beveled, said beveled end terminating adistance from the rearof the fire box.
In testimony whereof I aflix my signature.
