AIR AND GAS BURNER.

SPECIFICATION forming part of Letters Patent No. 416,130, dated November 26, 1889.

Application filed July 17, 1889. Serial No. 317,783. (No model.)

To all whom, it may concern.- stack From any suitable some of supply Be it known that I, JASPER M. \VALTERS, a there leads the gas-pipe 4, provided near the v citizen of the United States, residing at Findboiler with a suitable valve 5, and terminatlay, in the county of Hancock and State of ing, preferably below the floor, in an imperfo- 5 Ohio, have invented a new and useful Air rate spherical chamber or mixer 0.

the usual fire-box 2, and above this boiler and If desired, I may provide the hot-air pipe 9 communicating with the firebox the smokewith a valve, (shown by dotted lines in Fig.

1,) whereby the circulation of air does not take place until the air above the burner has become heated, when said valve is opened. Such a construction also prevents an upward rising of the gas through the pipe 9 when the valve 5 is first opened. This tendency, however, is overcome by the pipe t terminating near to the eduction end of the pipe 7.

By reason of forming the mixingphamber imperforate the whistling, roaring noise so objectionable is avoided and the gas deodorized.

Havingthus described myinvention and its operation,what I claim is- 1. In a burner of the class described, the combination, with a mixing-chamber, of a burnerpipe leading therefrom and terminating in a burner,a gas-supply pipe terminatingin said chamber, and a hot-air pipe communicating with said chamber and terminating in a line of draft with the burner, substantially as specified.

2. In a burner of the class described, a mixing-chamber, a supply-pipe, and a gas and air pipe extending therefrom and terminating in a burner, in combination with a hot-air pipe communicating with the chamber and having its opposite end flared and arranged above the burner, substantially as specified.

3. In a burner of the class described,a mixing-chamber, an air and gas pipe leading therefrom and terminating in a burner, a

in the mixing-chamber and in line with the air and gas pipe, substantially as specified.

4. The combination, with a steam-boiler 1, having the fire-box 2 and the smoke-stack 3, of the 1nixing-chamber 6, located near the boiler and having the enlarged gas and air pipe 7, terminating in the burner 8, and the enlarged hot-air pipe 9, communicating with the chamber and terminating at its opposite end in the flared mouth 10, located in the smoke-stack, and the gas-pipe 4, smaller than the pipes 7 and 9 and provided with the valve 5, and terminating in the mixing-chamber and opposite the pipe 7, substantially as specified. 5. In an air and gas burner, the imperforate chamber 6, having a burner-pipe 7, terminating in a burner, the hot-air pipe 9, terminating in the flared mouth 10, and the gassupply pipe 4, terminating in the mixer, all combined as specified.

6. The combination, with a steam-boiler 1, of the mixing-chamber 6, located near the boiler and having the gas and air pipe 7, terminating in the burner 8, and the hot-air pipe 9, communicating with the chamber and terminating at its o posite end in the flared mouth 10, located in the smoke-stack, and the gas-supply pipe 4, leading to the mixingchamber, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

JASPER M. WALTERS.
