COMBINATION HEATER.

Application filed April 18, 1921.

This invention relates to stoves or heaters but more particularly to such as are capable of burning either fluid or solid fuels and has for its primary object to provide a simple, economical and effective heater of this class.

Further objects provide improved com eliminate fluid fuel of the invention are to on of the fuel, to

our combustion chamber, to reduce the cost of production, to facilitate the use of bituminous coal, and in general to provide an improved heating apparatus.

The many other objects advantages of the invention will be better understood by reference to the following specification when considered in connection with the accompanying drawing illustrating a selected embodiment thereof, in which Fig. 1 is a central vertical section of the heater, and V Fig. 2 is a section on the line 22 of Fig. 1.

Referring to the drawing, the heater comprises a casing 5 mounted on a basefi and provided with a solid fuel grate 7, an ash receiver 8, doors 9 and 10, and a flue 11. The door 9 is provided with the usual damper to regulate the admission of air beneath the fire-box. An opening 12 is provided in the top of the casing and the wall about this 0 ening is preferably depressed to form a socket 13. A seat 1% for a rotary damper 15 is provided in this socket.

A. pipe 16 passes through the opening 12 and is supported by its flaring upper end 17 which fits within the socket 123. A fluid fuel nozzle 18 projects through the damper 15 and is fed by the supply pipe 19 provided with a control cook 20.

l lhen fluid is being used, the pipe 16 acts as a large Bunsen burner. The fuel enter this pipe from the nozzle 18 and is mixed with air admitted through the damper 15 about this burner. Combustion takes place at the base of the pipe 16 and a hot blue flame is projected therefrom. If the fluid Serial .No. 462,241.

fuel is to be used exclusively over, an extended period, it is advisable tofill the grate with broken stone, brick or other similar non-combustible material. The flame from the pipe 16 quickly heats this material to a high temperature. The fuel supply may then be shut off and sufficient heat will be radiated by this material for a considerable period to maintain a proper temperature in the room. This results in a very material saving in fuel consumption. By the disposition of the pipe 16 above the flame, the combined air and fluid fuel therein becomes heated prior to combustion and a more complete combustion results. v

To operate the heater with solid fuel, the grate is filled in the usual way and the damper in the door 9 opened. The damper 15 is preferably closed until the paper and Wood have been at least partially consumed and the coal has been suficiently heated to commence giving oil gas. At this time the lower damper is preferably closed and the damper 15 opened to cause a blast of heated air to enter the combustion chamber from the pipe 16. This hot air mixes with the gas and complete combustion takes place. As soon as the coal has ceased to give off gas, the damper 15 should preferably be closed and the lower damper opened as combustion will then proceed more advantageously by admitting the air supply below the grate.

The entire heater is exceedingly simple in construction and may be economically produced. Improved combustion of both fluid and solid fuel is procured and a material saving in both solid and fluid fuel consumption is provided. The usual perforated fluid fuel pipes in the combustion chamber are eliminated. The perforations in these pipes quickly became filled by the dust and ashes and required constant attention. The holes in the heater necessary to admit these pipes are likewise eliminated. The hot air blast above the fire provided by the depending pipe obviates the danger of escaping gas so frequently resulting from incomplete combustion and thus renders the use of soft or bituminous coal for room heaters entirely safe and practical.

I am aware that many changes may be made in the form and arrangement of parts without departing from the spirit of my indirectly exposed to the burning gases in said combustion chamber, and means for provid ing regulated supplies of air andgas to the upper portion of said burner pipe, the latter having a discharge outlet adjacent and above the top of said firepot and arranged to project downwardly into either a blast of hot air or of a highly heated mixture of air and gas, substantially as described.

2. A combination coal and gas heater comprising a casing having a firepot for containing coal or refractory material, a combustion chamber above the firepot and an ashpit below the same, a hot blast pipe depending within the central portion of said combustion chamber, a damper at the upper end of said pipe for controlling the admission of air to said chamber through said pipe, a fluid fuel supply pipe projecting i lsiaoee through said damper, and a control cock in downwardly into said firepot either a blast of hot air or a highly heated mixture of air and gas, substantially as described.
