I GAS HEATING STOVE OR FURNACE.

SPECIFICATION forming part of Letters Patent No. 747,928, dated December ,1903; Application filed November 2 1, 1902. Serial 110.1321250. (N0 model.)

. To all whom it may concern:

- Be it known that we, WILLIAM SIMON BECH- TOLD and ADOLPH FABER DU FAUR, J r., citizens of the United States, residing at Newark, in the county of Essex and State of New J orsey, have invented certain new and useful Improvements in Gas HeatingStoves or Furnaces, of which the following is a specification.

Our invention has reference to improvements in gas heating stoves or apparatus of that class particularly adapted for heating individual rooms, and has for its objects, first, a proper and complete combustion of the gas secondly, an improved distribution of the flame; thirdly, an improved presentation of radiating-surface; fourthly, the prevention of obnoxious gases entering the room, and,

fifthly, the reduction of the running expenses in a marked degree.

With these objects in view our invention consists, essentially, in a gas heating stove or apparatus comprising a base and a spreader forming between them flame channels increasing outwardly in width and depth and extending from a common point, a burner adapted to direct a flame toward the common 7 point, a series of tubes adapted to receive the several jets, and a top chamber.

The nature of our invention will best be understood when described in connection with the accompanying drawings, in which- Figure 1 represents a vertical central section of a heating-stove embodying our invention, part being broken away. Fig. 2 is a horizontal section on the line 22, Fig. 1. Fig. 3 is a horizontal section on the line 33, Fig.

I 1. Fig. etis a perspective view of the spreader.

of a central jet by means of the burner B, as

well as the introduction of air around said .burner. The burner B may be of any usual type, although we prefer to use the specific construction herein shown', which consists of a bell b, secured to the legs or other support attached to the base A, a mixing-chamber 2, and nozzle 3, forming the flame-nozzle. I In line with the mixing-chamber 2 is arranged a-gas-nozzle D, which is connected with the gas-main either by the usual piping or by rubber hose in the usual manner. The gasnozzle is provided with a tip having a perfo-- ration of small area for the passage of gas, and the flow of gas can be regulated by a cock E in the usual manner. The admission of air can be regulated by moving the gasof said spreader and forming, with the inner,

surface of the base A, a series of flame-channels'f, also increasing in width and depth outwardly from the apex of said spreader, the purpose of said flame-channels being to direct the flame with gradual lateral expansion outwardly toward and into a series of tubes H, the connection of which said tubes with said base will presently be described. It will be readily understood that flame-channels of the characterdescribed can also be formed by providing the base A with the same grooves f as described in connection with the spreader F or by providing both the base and the spreader with said grooves. In the former case the spreader could be made perfectly smooth. It will be noticed from the drawings that this spreader is made of considerable thickness, and consequently the lower surface of said spreader is heated to a relatively high temperature, heat being transmittedthrough a considerable thickness of metal to the upper surface or surfaces, which are exposed to the air of the room, and thereby kept at aconsiderably lower temperature,"sof as to prevent scorching, as in the ordinary heatingstoves, where the air is exposed to very highly Y embodied in an elliptical stove, the spreader heated surfaces in proximity to the flame and in other parts of the stove.

The base A is closed at its top by plate G, provided with a series of concentric openings g and with vertical flanges h, adapted for the reception of vertical radiating-tubes H. The tubes H have their upper ends entered into a chamber I, having suitable flanges h for this purpose, and which may be provided at its top with an opening t', closed by a suitable removable cap J. This chamber I has an exit or draft opening j, connected with the chimney or the exterior of the building by means of a pipej in order to permit the escape of the obnoxious gaseous products of combustion. This draft connection is, however, not absolutely essential, as the stove will be just as eifective without such draft connections; but this draft connection prevents the escape of obnoxious gases into the room and renders the stove entirely odorless under all circum stances. I

The top of the chamber I may be formed with an opening 2', adapted to be controlled by the cap J, which is slotted circumferentially, as at 7?, for the purpose of permitting air heated by the stove to enter the room, if so desired, or the cap may be removed and shifted to an eccentric position for the same purpose or the cap may be entirely removed with but slight escape of noxious gases into the room in view of the chimney-draft.

As shown in Figs. 1 and 2, the spreader extends through the openings gin the top plate of the base A and into the radiating-tubes H, it being recessed, as at 3 3, at the proper intervals along its upper edge forthis purpose, and consequently the spreader causes the introduction of the flame into the individual tubes at any desired point, according to the diameter of said spreader.

In practice we prefer to introduce the flame along a line inwardly from the center of the tubes, so as to obtain asubstantially central jet in each tube.

In practice we firmly unite the spreader to the cover of the base and to the bottom of the upper chamber by a bolt L and a suitable nut, although ordinary means may be employed for this purpose.

It will readily be understood that in the present construction for gas heating-stoves absolutely perfect combustion is obtained, since the burner B, first, produces a substantially perfect Bunsen jet; secondly, the jet is spread comparatively flat and mixed with air drawn in through the opening 1 in the base; thirdly, acomplete burning mixture is formed in the tubes H and chamber I, and, fourthly, the heavier gaseous products of combustion are carried off through the pipe j, thus producing an entirely sanitary stove.

While in the present instance we have shown a circular stove, it is of course to be understood that the same principle can be then being made elliptical inform, or the stove may be made rectangular either with adouble or single row of tubes. The spreader can then be correspondingly formed.

It is of course to be understood that we do not wish to restrict ourselves to the general construction of the heatingstove herein shown-that is to say, in so far as it relates to the tubes, upper and lower chambers, and their particular connections-as our invention consists, essentially, in the means for spreading and directing the flames from a burner.

A gas heating stove or apparatus comprising a base and a spreader forming between them fiame-channels increasing outwardly in width and depth and extending from a common point, a burner adapted to direct a flame toward the common point, vertical hollow radiating means adapted to receive the several jets, and a top chamber, substantially as described.

3. A gas heating stove or apparatus comprising a base and a spreader forming between them flame-channels increasing outwardly in width and depth and extending from a common point, a burner adapted to direct a flame toward the common point, vertical hollow radiating means adapt-ed to receive the severaljets, and an air-inlet in the base adjacent to the nozzle of the burner, substantially as described.
