To all whont it nuty concern.-

Be it known that I, EDWARD BURDEN, engineer, a subject of the Queen of Great Britain and Ireland, and a resident of DesboroVilla, Dysart road, Grantham, in the county of Lincoln, England, have invented certain new and useful Improvements in and Relating to Gas or Oil Stoves, (for which Ihave made application for Letters Patent in Great Britain, No. 12,434, bearing date June 2, 1898,) of which the following is a specification, this application beinga division of my previous application, Serial No. 706,375.

My invention relates to stoves, and has for its object to provide a stove in which the air to support combustion is initially heated to secure perfect combustion and a stove in which effective provision shall be made for inducing circulation of air,so that thereby warm air shall be disseminated throughout the apartment in which the stove is placed.

My invehtion consists in the arrangement and design of a gas or oil stove in which the air for supporting combustion is conducted from an orifice or perforations in the stove casing, at the lower part thereof, upwardly to horizontal passages around a flue situated above the central burner-chamber and then downwardly to an air-chamber situated below the burner-chamber, the air beingheated during its passage by the radiant heat from thewalls of the passages and finally issuing from the air-chamber through perforations into the burner-chamber. The air for combustion being heated as above described, a perfect combustion of the flame or flames is insured and the dissemination of deleterious products of incomplete combustion that generally ensue in the use of ordinary gas or oil stoves is obviated.

The invention is illustrated in the accompanying drawings, in which Figures 1 and 2 are respectively front and side sectional elevations of a stove constructed according to one modification, while Figs. 3 and 4. are similar views of a stove constructed according to a second modification.

In carrying my invention into efiect accordand 2 I arrange the airfor combustion to pass from below the stove-casing E F through a passage G at one side of the casing, then through side flue s G G provided upon the front and back-of the upper part of the casing E, and then again downwardly through a passage G upon the other side of the stove to an airchamber II, situated beneath a central burner-chamber F,the air passing up through an upper perforated plate H into the burnerchamber. (v A refractory inset M is laid in the spaces between the side flues G and the air in its passage through such side flues is heated thereby, while a grid or series of refractory bars M, preferably of V shape and integral with the inset M in their disposition in line, provide a series of gradually narrowing spaces me, so that thereby a relatively great area is provided for the interception of the products of combustion in the upward passage. I may, however, cause the sides of the side flues to be completed by means of the refractory inset 1 as illustrated in Figs. 3 and t, so that thereby the air shall come into actual contact with the sides of refractory material. In such a case the stove-body may have its upper partof dome shape and the responding shape, with flanges m upon the upper edges, which engage with the sides of the casing E. In such a design, however, an outer casing E may be employed surround diate space G being preferably employed as a passage for air from the base of the stove. Such outer casing may be simply provided around the sides and top of the stove.

Having thus described my invention, what Iclaim as new, and desire to secure by Letters Patent, is

1. A gas or oil stove consisting of a central burner-chamber and lateral air-fines connected by transverse flues, the air passing up one of such lateral fiues from the base of the stove, along the transverse flues and down the other lateral flue issuing through to the burnerchamber substantially as described.

2. A gas or oil stove consisting of a central ing to the modification illustrated in Figs. 1

burner-chamber and lateral air-flues, the air refractory inset may be constructed of a coring the central inner casing E, the intermepassing up one of such lateral fines from the base of the stove along the transverse lines and down the other lateral flue issuing through to the burner-chamber, the inner Walls of the side fines being formed by a refractory inset or flue centrally disposed above the burnerchambersubstantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.

EDWARD BURDEN.
