SZPECIFIGATION forming part of Letters Patent No. 540,468, dated June 4, 1895.

w Application filed October 29,1894. Serial No. 527,168. on model.)

T0 at whom it may concern:

Be it known that I, GEORGE THOMPSON, a citizen of the United States, and a resident of the city of Vincennes, in the county of Knox and State of Indiana, have invented certain new and useful Improvements in Stoves, of which the following is a specification.

The several features of my invention and the various advantages resulting from their use conjointly or otherwise, will be apparent from the following description and claims.

In the accompanying drawings, making a part of this application, and in which similar letters of reference indicate corresponding parts, Figure 1 represents a central vertical section of a stove embodying my invention. Fig. 2 is a compound view,to wit: The righthand half of this figure represents a part of the true top of the stove, the ornamental superstructure being removed. In this righthand portion'is seen the one-half of a metallic represents a plan view of either half of the Fig. 4 represents a perforated middle ring. vertical transverse section of any side of the upper portion of the stove, and showing, among other things, the mode of joining the vertical drum and the upper or top part of he stove and the perforated nickel ring. Fig. 5 represents a vertical transverse section of the stove at and in the vicinity of the perforated middle ring, and also of the adjacent side of the fire-pot and the adjacent portion of the bottom of the latter.

The class of stoves to which my invention is applied is known as the radiating stove.

. The base A of the stove is supported on legs A and is made of any suitable form to sup:

port the basal or foundation portion of the fire pot B. This base A preferably contains the ash pit A as shown,and the ash-pit contains the ash pan A capable of being, at will,

withdrawn from the stove, and emptied, and

the raised ring C. On the ring B and against the inner side of ring 0, rests the lower edge of the Vertical portion B of the fire pot B.

The bottomB hasin it the usual grate, and consequent openings of any desired kind.

Outside of the ring 0 is a horizontal ledge 0 on which latter rests the foot or lower edge of the casing D,-surroundiug the fire pot B. There is a space E between the fire pot B and casing D.

Outside of the ledge 0 the basal portion of fire pot extends'out and is carried down so as to rest in any proper manner upon the base or foundation A; One mode of thus extending said portion is shown in Figs. 1 and 5, and consists in thecxtension O O substantially as indicated. I I

The central or mid portion of the stove consists of two concentric drums, with a space H between. The outer drum F is preferably made of Russia iron, and the inner drum G of steel. In and through the sides of this drum is the door I, of any suitable size and kind. V

The connection between the middle portion of the stove and the lower or fire pot portion will now be described.

Alittle below its upper edgeand at its exterior, the fire pot- B has a horizontal flange B extending out to the casing D and forming a lateral support for the latter. The inner mid drum G rests upon this flange B its lower end fitting into a recess B in the upper side of the flange next to the fire pot.

At the outer side of the lower portion of the drum G is a vertical ring K. This vertical ring K isriveted at K to the drum G. Lugs or extensions K extend horizontally outward. The location of the ring K, K on the drum G is such that the lugs K do not touch the flange B of drum B but are located at a distance above it. The object of such location is to enable the securing bolts K (which pass through the lugs K and flange B to hold the ring K, K to the flange B to tighten and draw down the ring and mid drum G so that the bottom of the latter rests securely in place in the groove B This effect could not be accomplished by these bolts if thelugs K in the firstinstance and before being drawn upon by bolts K rested directly upon the flange B The flanges or lugs B do not extend out en tirely across the space between the pot B and the casing D, and ample room is given for the air heated between the fire pot B and the casing D to pass it or them and circulate upward into the space H between the mid drums G and F.

I will now describe the perforated middle ring M. This ring islocated above the flange or lugs K Its inner edge rests upon the upper edge of the ring K. It extends out across the space II, and abuts against the inner side of the drum F forming at M a lateral support for the latter. From the lower outer edge of this ring there extends outwardly a flange or extension M which curves out and downwardly. On the top of this extension M rests the drum F, and this extension M in turn rests upon the upper edge of the casing D. The surface of the ring M between drums G and F and below space H is perforated at at close intervals. These perforations M (see Fig. 3) allow the air of the interspaces E and H to freely circulate. The ring M is held down securely in place by means of bolts as M connected at one end to the flange or a lug B and at the other to the ring substantially as shown. These bolts go through the portions Mof the ring left between the perforations. The ring is made in two or more sections, and theseveral sections are bolted to one another end to end. A provision for thus uniting the sections is shown in Fig. 5, and consists of the flange M proj ecting down from the end of the extension M as shown, and perforated for the reception of a bolt securing said flange to a similar one of an adjacent section. This mid-securing device is wonderfully compact, simple, strong, economical of manufacture and readily put together, adjusted in position and readily taken apart for repair, due.

The top N of the stove carries a series of horizontal lugs N extending outward from it and spanning the top of the space H between the drums G and F. These lugs rest on the top edges of the drums F and G. \Vith the drum G and abutting against the inner side thereof is a down flange N projecting from the said top N. Angular corner irons or ring N bolted to the outer side of the upper end of the drum and to the lugs N hold the top N and drum G firmly together. The top N also carries the perforated ring N extending out and curved over and down. This ring is provided with perforations N at comparatively close intervals all the way around it. The hot air passing up from spaces E and H passes up past the lugs N and in part passes out through the perforations N. The hot air passing up along the outside of the outer mid drum F and close thereto, is caught under the curved ring N The most part of this air passes up through the perforations N of ring N While the various features of my invention are preferably employed together, one or more of such features may be used without the remainder, and in so far as applicable one or more of said features may be employed in stoves other than the one herein specifically set forth.
