IMPROVEMENT lN COAL-STOVES.
Specification forming part of Letters Patent No. 102,328, dated April 26, 1870.
1, JAMES SPEAR, of the city and county of Philadelphia and State of Pennsylvania, have invented certain Improvements in Stoves,'of which the following is a specification:
The nature of my invention consists in the construction of the fire-pot of a stove or heater so provided with an opening near its front and base, and a hearth in connection therewith, that the clinkers formed in the grate can be removed without the necessity of making a new fire, and in the construction and arrangement of the grate in relation to the base of the stove. v
To enable others skilled in the art to make and use my invention, I will now proceed to describe its construction and operation, reference being bad to the accompanying drawings, in which Figure 1 is a general view of the base, showing the basketgrate inside. Figs. 2, 3, and 5 are sections through my grate, showing various modifications of the same improve- Fig. 4 shows the grate made solid as a substitute for the basket-grate. Fig. 6 is a perspective view of my grate, showing the opening in front and the hearth-plate.
In Fig. 1, A is the base of the stove; B, the door of the ash-pit; C, the door through which the pokers are inserted for shaking and dumping the grate. D is another opening at a level just above the grate-bars, through which the state of the fire at the bottom of the fire-pot may be observed. This opening is closed by doors E, which have therein transparent lights 0, so that the base may be entirely closed air-tight, and the state of the fire still be visible in the grate.
In Fig. 2, G is a band or ring at the top of the basket-grate, to which the bars 9 are secured. They are connected at the bottom by a ring, h, as shown in Fig. 5. The bars K, at the front of the grate, do not reach to the bottom within two or three inches, so that an opening, K, is made, through which the cinders and clinkers can be pulled out with a poker. Beneath the opening K I project a hearth-plate, M, upon which the coals or cinders which escape through the said-opening will bank up at their natural inclination, and the fire is thereby prevented from falling out. The bars K are also projected inward rather more than the bars 9, so as to avoid the-necessity for extending the hearth-plate M too far out. In this Fig. 2 the grate-bars N and hearth-plate M are all rigid together, and turn upon the center-pin 'n. A poker is inserted through opening 0 in the base, and into the hole 1", by which the grate is vibrated.
In Fig. 3 a flange, o, is shown around the top of the fire-pot, by which it is suspended; the hearth M is rigid to the grate. The grate N vibrates upon a pivot, n, independent of the basket.
In large heaters, where the heat is not required in the base of the heater, I make a solid basket, (see Fig. 4,) supplied with an opening in the front K above the hearth M, and also with a vibratory and dumping grate, P. In large fire-chambers for heaters it would require too much strength to move the entire basket when solid matter is here shown. By this plan, however, the same advantages can be gained, the slate and clinkers are easily removed, and a perpetual fire kept going.
The grate in Fig. 5 is'nearly similar to that in Figs. 3 and 4. It is vibrated on a centerpin, it. The grate P is supported on pivots n, and has a depending arm, R, to which a rod, S, is hooked, for dumping the grate and letting out all the ashes whenever required.
It is evident that the opening K may be made at the rear of the fire-pot, as in front, if desirable.
Having now, described the construction of the parts, I will further state the advantages derived therefrom. One of the objections to stoves now in use is this, that the grate is certain in time to be clogged with slate and clinkers, rendering it necessary for the fire to be put out,'and the grate dumped at certain intervals. This is especially inconvenient in those stoves called reservoir-stoves, also in heaters, as the fire is expected to be kept in night and day for a long time. By this construction of grate the clinkers which will not pass through the grate-bars are easily removed through the opening K by means of a hooked poker, and the fire thus kept in as long as the stove will last.
In constructing my grate for parlor-stoves, where the heat is required near the floor, I make it in a basket form, as herein shown, and supported in the base of the stove with the usual pivot-bar. By dropping the grate into the base of the stove I thereby lengthen The grate G, with opening K in front, and I the depth of the fire-chamber, and thus throw hearth-plate, M arranged within the base A, a greater heat into the base of the stove. substantially as herein described. a
I do not broadly claim the hearth M,,when JAMES SPEAR. it forms the hearth proper of the stove. Witnesses:
What I claim as my invention, and desire JOHN P. LEY, to secure by Letters Patent, is 1 A. EIGKMEYER.
