SAFETY-PLATE .F R sTovEs;

SPECIFICATION forming pi't of Letters Patent No. 592381, dated October 26, 1897. Application filed March 25, 1 897. Serial NO. 629,264. (No model.)

i Mauch Chunk, in the co'unty of Carbon and State of Pennsylvania, have invented a new and useful'Safety-Plate for Stovcs, of which the following is a specification.

This invention relates to safety-plates for stoves, its object being to provide aplate to be used in addition to the ordinary stove-lid, which plate will fit into the ordinary opening in the top of the stove and will also receive the ordinary stove-lid. The plate is perforated in order to permit the fire to be damped or checked and at the same time prevent the coals from flying out of the stove.

WVith this object in View the invention consists of a stove-plate constructed as hereinaf- A ter fully described.

In the drawings, Figure 1 is a perspective view of a portion of a stove, showing my 'safety-plate in position in one of the openings, the ordinary stove-lid being removed. Fig. 2 is a section through a portion of the stovetop, the safety-plate, and stove-lid. Fig. 3 is a perspective View of the safety-plate detached. Fig. & is a top plan View of the same. Fig. 5 is a plan view of the ordinary stovelid detached.

Similar reference-numerals indicate similar parts in the several figures.

l represents the stove-top, and' 2 the ordinary circular opening therein.

3 represents the safety-plate, which is provided with a series of perforations 4. The plate 3 is adapted to fit in the stoVe-opening 2 and is provided withan annular fiange or rim 6, adapted to fit in the usual recess around the stove-opening to be flush with the upper surface of the stove-top. The rim 6 projects above the perforated plate, and a recess is thereby forned for the reception of the ordinary stove-lid 7 and the flange 6 is also rabbeted, as indicated at 5, to receive the usual annular fiange or rim of the stove-lid, and in this manner the stove lid when in position will also be flush with the upper face of the stove-top and its lower surface be in contact with the perforated portionof the safetyplate,and thus effectually exclude the passage of air through the perforations in the safetyplate. The stove-lid 7 is providedwith the usual projection or lug 8 on its lower face and With the opening 9 in its upper face, immediately over the lug to receive the lifter. The safety-plate 3 is provided with a recess 10, into which the lug 8 projects when the stove-lid is in position, and immediately below this recess a projection 11 is provided on the under side of the plate in order to keep the metal platc of a substantially uniform thickness. Another recess 12 is formed in the rim 6 of the safety-plate for the reception of the lid-lifter when it may be necessary to lift the safetyplate and the stove-lid together out of the opening 2 in the top of the stove.

From the foregoing description it Will be readily seen that when it is desired to damp or check the fire the stove-lid 7 may be removed and air will pass through the perforations 4: in the safety-plate onto the burning coals, and at the same time should the burning coals explode or burst, as they frequently do on account of the sulfur and gas contained in them, they Will not be able to fly out into the room and possibly cause a fire. It is 'a common practice to tilt the ordinary stove-lid to one side and sometimes to entirely remove it in order to checkthe fire, but this is a dangerous practice, as frequently the burning coals will fly outthrough the stovelid opening and sometimes cause a confiagration. WVhen the stove-lid 7 is in position on the safety-plate, air will be entirely excluded from the top of the fire and combustion will not be checked, and the heatwill be conducted to the outer surface of the stove-lid as effectually as if the safety-plate were not present. in any manner interfere with the free burning of the fire only when the stove-lid is removed.

What I claim is- 1. A safety-plate for a stove adapted to be removably fitted in the ordinary circular stove-lid opening', and having a depressed central portion provided with a series of perforations to admit air to the top of the fire, said depressed portion being of such form and dimensions that an ordinary stove-lid may be removahly seated therein, and when in position in thedepressed portion will close the The safety-plate therefore does not IOO perforations against the passage of air to the fire, suhstantially as and for the purpose deseribed.

2. The conbination with a Steve-top pro- Vided with a eireular opening having a rabbet 01' recess around its edge, of a perfo'ated plato adapted to fit loosely in said opening and having an upwardly and outwardiy projeeting annular fiange adapted to be seated in the reeess around said opening to be finsh with the top of the stove, said flange having a rabbet or reeess around its inn er periphe'y, and a stove-iid adapted to fit within the fiange of the perforated plate and be looseiy supported on the perforated portion of the latter, said stoVe-hd having an annular flange to fit in the 'eeess 01' rabbet in the fiange of the perforated plate to be flush with the stevetop, the Steve-lid being separately renovable and the pe'forated plate and the stove-lid being renovahle together, substantially as described.

In testinony that I claim the fo'egoing as my own I have hereto afiixed inysignatnre in the presence of two witnesses.

FRANCIS H. A. DEVLIN.
