FiRE-POT FOR BOILERS.
SPECIFICATION forming part of Letters Patent No. 273,012, dated February 27, 1883.
Application filed September 6,1882. (N0 model.) I
To all whom it may concern:
Be it known that I, EDWARD P. BATES, of Syracuse,iu the county ofOnondaga and State of New York, have invented a certain new and useful Improvement in Fire-Pots for Boilers, of which the following is a specification.
My improvement relates particularly to steanrboilers, such as are used in houses and other buildings for generating steam for heatin g apparatus.
The improvement consists in'the combination, in a steam-boiler, of a water-chamber, a
fire-pot, flues extending from the upper part of the fire-pot through the water-cham her, and serving to conduct heat and to carry Waste products of combustion fromthe fire-pot, an outer casing surrounding the fire-pot and wator-chamber, and a number of coal-feeders extending downwardly at angles from the exterior of the outer casing to opposite portions of the fire-pot, so as to deliver fuel around the fire-pot, the wall of the fire-pot being closed entirely around except where the coal-feeders open into it. I also preferably combine with the above an automatic draft or damper regulator.
The invention also consists in a novel combination of parts hereinafter described.
.In the accompanying drawings, Figure 1 is an outside view of a steam-boiler embodying my improvement. Fig. 2 isa central vertical section of the same, and Fig. 3 is a horizontal section ther of.
Similar letters of reference designate corresponding parts in all the figures.
' A designates a fire-pot, preferably made of wrought-iron. It is of a proper height to contain a deep and slow-burning fire, and to form a combustion -ohamber wherein combustible gases may be ignited before theproducts ofcombustion enter the flues B, which surmount it.
The shell or water space or chamber 0 of the boiler extends down around the fire-pot and up to the top of the tines.
The grate D is composed of a number of rocking bars. The ask-pit is of ordinary form. Outside the shell of the boiler is a heat-chamber, E, formed in the masonry M of the boiler. The masonry forms an outer casing for the boiler. The products of combustion escape into this heat-chamber from the lines B. The heat-chamber has a removable cover, E, for iacilitatingcleaning. Fromthisheat-chamber the products of combustion pass into a flue, F, whereby they are carried off. The steam gensuitable pipe.
The boiler is furnished with a water-gage, H, a blow-off pipe and cock, I, and an open tube extending from the shell of the boiler just below the normal water-level, and affording a relief to the boiler upon the accumulation of excessive pressure in it. This tube must extend to a height corresponding to the pressure to be maintained in the boiler.
J designates an automatic water-feeder for maintaining the proper level of water.
K designates an automatic draft-regulator, which is actuated by the pressure of steam in the boiler to shift the ash-pit door L for varying the draft.
N designates the coal-feeders. They consist of spouts made of cast-iron or other suitable material, and extend through the side of the masonry and shell of the boiler to the tirepot. They are arranged at opposite points, and are here shown as four in number. They are filled with coal, and as the fire needs more coal it is automatically supplied. The coal is delivered by these feeders to the sides of the fire-pot. These feeders also serve the purpose of air-reservoirs, and as they nearly encircle the fire they conduct air to almost all parts of the fire.
If it is desirable to feed from only two or three sides of the boiler, I may employ, in conjunction with the feeders N, one or more branch feeders or chutes, 0, extending from a side or sides to a feeder or feeders, N, located in an adjacent side or sides.
It will be observed that the feeders N are of great width in proportion to their depth, and that where a number are arranged at opposite points they deliver coal around almost the entire circumference of the fire-pot, as is shown most clearly in Fig. 3. The fire-pot is closed entirely around except where the feeders enter it. The automatic draft-regulator and the inclined coal-feeders coact to maintain a uniform pressure of steam or degree of heatin the erated in the boiler is conveyed away by a' boiler and a uniform firein the fire-pot, and
.when provided with both the automatic draftregulator and the coal-feeders a boiler will need very little attention.
WhatIclaim as my invention, and desire to secure by Letters Patent, isr 1. In a steam-boiler, the combination of a water-chamber a fire-pot, fines extending from the upper part of the firepot through the water-chamber, and serving to conduct heat and to carry the waste products of combustion from the fire-pot, an outer casing surrounding the fire-pot and water-cha1nber, and a number of coal-feeders extending downwardly at angles from the exterior of the casing to opposite poriions of the fire-pot, so as to deliver fuel around the fire-pot, the Wall of the fire-pot being closed entirely around except where the coal-feeders open into it, substantially as specified.
2. In a steam-boiler, the combination of a water-chamber, a tire-pot, fines extending from the upper part of the lire-pot through the water-chamber, and serving to conduct heat and to carry the waste products ofcombustion from the fire-pot, an outer casing surrounding the fire-pot and water-chamber, a number of coalfeeders extending downwardly at angles from the exterior of the casing to opposite portions of the fire-pot, so as to deliver fuel around the fire-pot, the wall of the fire-pot being closed entirely around except where the coal-feeders open into it, and an automatic draft-regulator for controlling-the admission of air, substan tially as specitied. i
3. In a steam-boiler, the combination of the water-chamber O, the fire-pot A, fiues 13, leading from the upper partof the fire-pot through the water chamber, a number of coal-feeders. N, extending laterally at inclines to opposite parts ot the tire-potr'and serving to supply coal around the outer part'of the fire-pot, and a branch feeder, 0, extending transversely to one of the feeders N and adjacent to another of said feeders, substantially as specified.
