GRATE.

SPECIFICATION forming part of Letters Patent No. 709,377, dated September 16, 1902.

' Application filed February 26, 1902. serial No. 95,510. (No model.)

To an whont it may concern):

Be it known that I, JOHN THOMAS VAUGHN, a citizen of the United States, and a resident of Griffin, in the county of Spalding and State of Georgia, have invented a new and useful Improvement in Grates, of which the following is a full, clear, and exact description. Myinvention relates to gratesused in burning fuel. i

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claim.

Reference is to be had to the accompanying drawings, formingapart of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a front elevation of a fireplace employing my device, Fig.2 is a central section at right angles to the view shown in. Fig. 1. Fig. 3 is a perspective View of the fuelrack, and Fig. 4 is a perspective view of one of the end plates.

The chimney 1 is fitted with lugs 2 adjacent to the ash-pit 3 and used for support 1 ing thegrate-basket. The fender comprises arc-shaped bars 4 '6, connected by rods 5, and is disposed in front of the ash-pit. The grate basket comprises vertical bars 7, horizontal bars 8, bent upward at their front ends, as indicated inFig. 2, and curved cross-bars 9, i the lowermost of which connects the front en ds'of the bars 8 integrally together. Upon either sideof thefireplace are end plates 10, made of metal and provided with slots or fissures 22. These end plates are bent at 19, so as to form corners, and have each the general shape of a hollow wedge. The object of this construction is to enable the end plates ported by means of the lugs 12, 13, 14., and 5o 16, resting upon the respective front and rear portions of the grate-basket. This constructo present a fiat and mutilated surface obtion renders the fuel-rack substantially parallel with the bottom of the grate-basket and also provides for an intervening air-space between said fuel-rack and said bottom. The lowermost curved cross-bar 9 is provided with a plurality of lugs 15, which converge inwardly toward the fire and which form an additional support for the fuel-rack. These lugs are particularly desirable in new grates,

as they can be cast integrally without additional cost.

It will be noted that the fuel-rack is removable from the grate-basket, and thus rendered interchangeable. The end plates rest upon the fuel-rack and are self-adjustable in that the crowding of the fuel forces them into theirnormal positions. The air has no difficulty in passing upward through the apertures 22 of the hollow end plates, and is thus admitted to the fire at points disposed above the fuel-rack.

The fuelu-aok saves the grate-basket from burning out quickly and is inturn easyto replace at small expense. The end plates are not exposed to the hottest part of the fire and can be made somewhat lighter than the other parts, if desired. These end plates, too, can be replaced at a comparatively trivial expense. The fuel-rack can be adjusted and fitted to grates already manufactured, and even to grates already in use, by merely bringing the lugs of the-fuel-rack into engagement with the respective front and rear bars of the grate-basket. It will be understood that the cross-bars of the fuel-rack tend to prevent the same from warping when subjected to great heat. When fresh fuel is added to the fire, the shock or jar generally produced has more or less tendency to dislodge any ashes that may have accummulated either upon the fuel or upon the fuel-rack, but does not pack the fuel to an excessive degree. I

I find that grates constructed upon the principle above outlined have a marked tendency to prevent smoking and that they render the combustion of the fuel more perfect than would otherwise be the case, thus effecting a great saving in the expense of fuel and avoiding the vexation due to smoky chimneys. The bottom of the grate-basket can be cleared of ashes and cinders Without disturbing either the fuel or the fire.

Having thus described. my invention, I claim as new and desire to secure by Letters Patent- A grate, comprising a grate-basket pro vided with horizontally-arranged longitudinal bars so disposed as to form a substantially fiat bottom, and havingupturned ends provided with a substantially arc-shaped member integrally mounted thereon, a fuelrack provided with horizontally-arranged longitudinal bars disposed at right angles to the general direction of the bars of said gratebasket, said fuel-rack being provided at its front portion with upturned lugs for engaging said arc-shaped member, and provided at its back portion with depending lugs, each having a length substantially equal to the general depth of said grate-basket, and a pair of hollow end plates of substantially wedge shape, mounted upon saidfuel-rack and provided with vertical slots to afford ventilation,

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN THOMAS VAUGHN. Witnesses:

R. J. EDWARDS, J. H. SMITH.
