Specification forming-part of Letters Patent N o. 105,773, dated July y26, 1870.

To all `whom it may concern:

Be it known that I, CLARK BROWNELL, of the city ofTroy, in the county of Rensselaer and State of New York, have Vinvented anew and Improved Ventilating-'Platform for Stoves, Ste., of which the` following is a specification: `The naturelof my invention consists in the employment and construction of a veu tilatingplatform formed in two parts, one of them being a ring, rim, or frame level on top, and the level part raised a suitable distance above the-floor by means of a bent edge or rim thereto, extending `down to the oor, leaving a space under the level p art sufficient for the passage of air.` This ring or frame may be of cast or wrought iron, or any other suitable metal or material. The legs of a stove or 4the supports `of a furnace rest on the level part of this ring or-frame. `Theeenter part of this said ring or frame is the second part of my invention, l

and this' part I form in a cone or domed shape,

. so thatit rises .from its edges, which rest on the ring or frame above mentioned. Toward the center thereof, in and through the ben t edge or molded edge or rim of the ring-or frame at proper points, I have perforations oraperturcs for the admittance ofthe outer air to the interior underneath said `platform, which air rises toward the center or highest point of the central or domed part of the platform, and at that point'I have an` aperture or perforation, one or more,as necessary, to pernnt the air to' pass out from underneatlrsaid platform. The centra-l. or domed `part of the platform may be constructed of zinc or tin, or any other suitable metal or material. Y The object of this platform isto` furnish a `suitable place upon which a stove or furnace may rest, the legs or supports of the stove or furnace 'resting on the platform, and the platform resting on the Hoor.` The platform be ing of metal, and constructed in accordance V with my plan, is lire proofthat is, no tirecan be communicated from the steve to the door, oil-cloth, or carpet. The platform is kept cool (no matter how hot the stove maybe) by means ot' the aircirculating underneath, as described above, and it is easily kept clean, as the tendency of the dirt, etc., is to keep toward the outer edges. The central or domed portion 'beine readil removed 4allows eleaninor the e; .Y b platform underneath, when required. Y

To render it'more perfectly lire-proof I sometimes line the platform- Wholly or partly withl tin, cement, or any other suitable non-conducting material.

By constructing'l the central or domed .part

of tin, or something of that brightness, the.

.sweating underneath, and sometimes a pattern of theoil-cloth is found sticking to the under side of a piece of zinc when taken up after lying dat for some time. Then, zinc and all soft material Vbecomes indented' by the Ystovelegs, and so ruined, all of which injury is preventedA inthe use of my platform. The air-currents circulating underneath v prevent excessive heating, and by keeping the'atmosphere dry prevent sweat-ing underneath. In shape my platform` 'may be freund, oval,

square, Octagon, or any shape .or form suited to the size and shape of the stove or furnace,

.which is to stand or rest thereon, and may be made of 'any suitable material. Therey may also be extra supports of some' suitable kind to assist-in bearing the weight placed thereon, and .where required of considerable size and dimensions it may be castor otherwise constructed in sections.

, The domed central part may be luted or otherwise ornamented, and the ring or frame may be handsomely molded and properly decorated, so as to present a tasty appearance to the eye.

rlhe perforations through which the air passes may be small round holes, slots of suitable length, or open-work grating, as` may be preferred, or the air may pass in through notches in the bottom` edge of thevring or frame. Figure lis a perspective view' of a parlor- 'stove, resting upon one of my platforms. Fig.

. forms. Fig. 5 is a sectional view of one 0f nr @Fries at Dinto and under my platforms, arrows showing the air-currents. Fig.6is an oval-shaped platform. Fig.

7 is an octagonal-shaped platform.

. Like letters refer to like or correspondingparts. Arrows shou7 the direction of the aircurrents.

A represents the ring or frame. B is the level or horizontal .part of the same., C is the rim part of the same, upon which the whole rests. This part may be neatly molded, fluted, orv otherwise ornamented, and is of strength suicient for the purposes requisite. In and through this rim are the perforations or apertures at the sides and back, and may be placed where suitable, and in such numbers as will answer the purpose, which is to admit currents of air to the space underneath the platform, as shown in Fig. 5, the apertures marked D. `The central domed part E rests lupon the horizontal part of the frameB, its outer edges touching all around. The center point of the same is higher than its outer edge, and in the center, or at any other suitable place, I have apertures-one or more, as required-for the escape of the air underneath. This creates a circulation from outside through the apertures the ring or frame A, which current then rises tothe outlet-apertures.in the upper part of the domed center E, through which it passes and escapes.

lThe outlet-apertures are marked F, and may be of any shape or position suitable.

Thus it will beseen that a `constant circulation of air will he" kept lup'underneath the platform, which will prevent excess of heat, and promote dryness, and 'at the saine time We have a lire-proof platform for stoves, &c., to rest onyand also one that is ornamental, or may be rendered so. The space underneath the platfornr may be simply sulicient for the purpose, and the different parts may have any rise, as may be deemed best, and may also be constructed of' any material suited to the purpose. The apertures for inlet of air may be simply notches along the bottom edge ofthe rim or flange C of the frame A, if they should be found to answer the same purpose.

What I claim as my invention is- -1. The use and constructionof a 'platform of metal or ire-proof material, formed so that air may circulate underneath, passing in and outthrough apertures provided therefor, substantially in the manner and for .the purpose as described and set forth.

2. The construction and use of the ring or frame A with its level B, on which the weight of the stove rests, and its flange or rim C, or its equivalent, substantially in the manner and for the purpose as described and set forth.

3. The domed central part E or itsequivalent, as and for the purpose substantially as described and set forth.
