ALBERT HENRY EDDY, oF EDeEwooD STATION, RHODE IsLAND.

To allzu/1,0mz't may concern: 'f Y l Be it known that I, ALBERT HENRY EDDY, a citizen of the United States,'residing at Edgewood Station, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Gas-Heaters, ofy which the" following is a specification.

My invention has reference to an improvement in gas heating appliances and.V more particularly to an improvement in gas heaters of the Bunsen or high temperature type.

rIhe objectof my invention is to improve the construction of a gas heater of the Bunsen type, whereby a more perfect combus-` tion and a hotter flame is produced, with a minimum amount of gas, than has heretofore been done.

Further objects of my invention are to simplify the construction and operation and to produce an intensely hot flame at a minimum of cost for gas. l

My invention consists in the peculiar and novel construction of a gas heater of the Bunsen type, said gas heater having details of construction, as will be more fully set forth hereinafter' and claimed.

Figure 1, is a side view in elevation of my improved gas heater. Fig. 2, is a top plan view of the heater, and Fig. 3, is a vertical sectional view ofthe heater taken on line 3. 3. of Fig. 2, and showing the lower fixed valve member in full lines.

In the drawing, 5 indicates the base member and 6 the burner member of my improved gas heater. The base 5 is a comparatively heavy rectangular shaped block of metal having a gas inlet pipe 7, connected to a horizontal gas inlet duct 8 controlled by a transverse tapered plug valve 9, having a port 10. This valve 9 has a coiled spring 11 intermediate the side of the base 5 and the head of a screw 12 in the end of the valve, which holds the valve tight under spring tension and a handle 13 on the op posite end for operating the valve, which is limited in its opening and closing movements by stop pins 14. 14 on the base 5, as shown in Fig. 1. rIhe gas duct 8 connects with a central gas chamber 15, which first extends vertically through the base 5 and is internally screw-threaded at its upper and lower ends. A fixed valve member 16 is screwed into and closes the lower end of the gas chamber 15, and has the contracted cone-shaped upperend 17. A circular conbase 5',

centric lboss. 18 is formed `on the top of the and a vpilot-light tube 19 is secured to the base 5 and extends from the gas duct 8 upwardto the top ofthe burner 6, as shown in Fig. 3. i

The burner member 6 has a lower. hollow circular dome-shaped portion 2OI which fits over the boss 18 on the base 5, and merges upward into -astraight, contracted tubular portionl 21, which is further contracted at its upper end in the form of a truncated cone-shaped burner tip `22. |Ihe dome shaped portion20- has va seriesI of air inlet openings 23. 23 in its sides, a raised bottom 24 in which is a series ofholes 25 and forms' a mixing chamber '26. The bottom 24 carries a central vertical screw-'threaded valve member27 which screws into the upper end ofthe gas chamber 15 and has a central yvertical shaped valve seat 29 on its lower end, in a position' to engage with thel cone-shaped end 17 of they fixed `valve member'16,"as shown in`Fig. 3. p

l/Vhen lin use the pipe 7 is connected to a 'source of gas supply, not shown, and the gas turned on. The gasat the end of the tube 19 is lighted and forms a minute'pilot light. The valve 9 is opened, and the valve seat 29 raised out of engagement with the end 17 of the valve member 16, by turning the burner 6v until the required amount and force of gas through the burner 6 is obtained. The

gas rushing through the duct 28, mixing chamber 26, portion 21 and tip 22 is ignited gas duct 28 and a .conefi on the tip 22 by the pilot light on the tip of the tube 19. By this construction thev amount of gas is regulated bythe valve 9, the fo'rce of gas through the mixingchamber 26 is regulated by turning the burner 6 and the large size of the mixing chamber 26, as compare-d with the burner tip 22, gives a more perfect mixture of air and gas a more perfect combustion and a hotter flame at the burner tip 22, than has heretofore been obtained. Any gas when in operation that may escape from vthe chamber 15 by the valve member 27 would rise through the y Having thus described my inventionl I claim as nevv:-

l. A gas heater having a base, a central gas chamber in the base, a gas duct through the base into the gas chamber, a valve con- Y trolling the gas duct, a fixed valve member having a contracted cone-shaped end in the gas chamber, a burner having a comparatively large mixing chamber, air openings in the sides of the mixing chamber, a contraeted tip and a central valve member havinv a gas duct and a cone-shaped valve seat coaeting with the cone-shaped end of the valve member in the gas chamber, and means for rotatably and adjustably securing the burner to the base.

2. A gas heater having a base, a central gas chamber extending vertically in the base, a horizontal ygas duct through the base into the gas chamber, a valve controlling the gas duct, a valve member' in the gas chamber and closing the lower end of the gas chamber, a burner having a comparatively large mixing chamber, air openings in the sides of the mixing chamber, a contracted tip and a central valve member having a gas duct and coacting with the valve member in the gas chamber, and means 'for rotatably and adjustably securing the burner to the base consisting of screw-threading the valve member on the burner into the top of the gas chamber in the base.

3. A gas heater having a base, a central gas chamber extending vertically in the base, a horizontal gas duet through the base into the gas chamber, a valve controlling the gas duct, a tube extending upward from the gas duct for a pilot light, a circular raised boss on the top of the base, a valve member in the gas chamber, a burner having a comparatively large circular mixing chamber over the boss on the base, air openings in the sides of' the mixing chamber, a contracted tip, a raised bottom having a series of holes, and a central valve member having a vertical gas duct and coacting with the valve member in the gas chamber, and means for rotatably and adjustably securing the burner to the base, consisting of screw-threading the valve member on the burner into the top of the gas chamber in the base.

et. A gas heater having a base, a central gas chamber in the base, a gas duct through the base into the gas chamber, a fixed valve member in the gas chamber, a burner having a comparatively large inelosed mixing chamber, with air openings, a contracted burner tip and a valve member which enters the gas chamber in the base and coacts With the fixed valve member in the gas chamber, and means for rotatably and adj ustably securing the valve member on the burner, in the gas chamber in the base.

In testimony whereof, l have signed my name to this specification.
