IMPROVEMENT [N STOVE-GRATES.

Specification formin g part of Lettera Patent No.172,822, dated February 1, 1876; application filed January 14, 1876.

To all whom it may conaern:

Be itknown that I, GEO. R. MOORE, of the city and county' of Philadelphia, in the State of Pennsylvania, have invented n'ew and useful Improvements in Stove-Grates, which improvements are fully set forth in the following speoifioation, refereneebeing had. to the accompanying drawings.

The objeet of my invention is to provide such facilities,in oombinatiori with stove and. hater grates, that ooal-fires may be more easily kept clean.

Figure 1 is a perspective view of the baseseotion of an ordnary stove containng a grate in combination with my improvements. Fig. 2 is a plan view of the same witli-tbe top plate removed.

A is the easing; B, the grate; C, manual hanger, 10osely jointed ,to the levers below, upon which the grate is bang, and provided with teet-h 0 for holding upon the easing, throngh which it passes at any desired poiut.

D is an extensible lever,to be used in lifting 0 when very heavy grates are used. a is a guide to D, and prevents its aceidental removal fromthe heater.

E F G are conneoted levers, loosely jointed together in triangular form'at their respective ends. E is pivoted at b, ami E at 01. G is provided With a central socket, whieh receives its counterpart (a vertical stem) from the center of the grate. His'a pull-rod for vibrating the grate hori zontally. I is a sx'nall doorway' to the under side of the grate when that is up, and to the upper side of the same when it is down, so that a band-poker may be used convenien tly on eithe'r side of the grate by adjusting it as required.

The operation of the levers is sueh that the grate is carried up and down upon a horizontal level as longas the front ends of E and G are kept together, as in this case; but the front ends ofE and G may be left free, and

moved separately, and the grate then carried upflor down, so as to incline ether way at w1 o It is easierstarting .fire,and less kindlings are required, when the grate is up, so that but little air can pass into the fire-ohamber without passing through it; but when the refuse produots of oombustion are to berennove'd the operation is more rapidly and easily done by dropping the gratedown, and then vibratng it rapidly it Will disoharge its load over -its periphery..

I am'aware thai: it.is usual todrop some part of a grate, or even the whole of it, in order more eonveniently to get at the fire to clean it but my improvements are seen in the deviees I have brought together aiid com bined for doing this.

I have had regard to preservin g a elear space around the grate; also,to the woidanee of ust.

The whole ofieration may ordinarily be performed. without opening any parl of the heat' er. .The aperture's through whih the rod H and the hanger 0 pass will not allow the es upon the adjustable levers, as shoW'n, the rod H, as and for the purpo se herein set forth.

3. The manna] hanger O, in combination With the levers E F G, substantially as shown.

4. The extensible lever D, in eombination With the hanger C, substantially as shown.

.5. In eombination,the heater-base A, grate B, and. levers E F G, substantially as Shown.
