JAMES MUSGRAVE, OF CINCINNATI, OI-IIO.
SPECIFICATION forming part of Letters Patent No. 302,015, dated J'uly,15,1884.
' Application filed December 10, 1883. (No model.)
To all whom it may concern.-
Be it known that I, JAMES MUSGRAVE, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Gas-Stoves, of which the following is a specification. I
My invention relates to animprovement'in gas-stoves; and its object is to provide, in combination with an upright burner pipe or tube and a horizontal air-induction tube, a perforated cap fitting over the outer end or mouth of said air,-tube, to regulate or cutoff the sup.- ply of air to the burner.
In the accompanying drawings, Figure 1 is an elevation of my improvement. Fig. 2 is a central sectional elevation of the stove,omitting the lower end of the burnertube, the air and gas induction pipes, and the supporting-legs. Fig. 3 is a plan of Fig. 2 on a reduced scale. Fig. 4 is a sectional plan on line 00 m, Fig. 2. Fig. 5 is a sectional elevation showing the gas-discharge jet and the elbow connecting the gas-supply pipe with the burner and air-tube coupling. Fig. 6 is a sectional plan on line yy, Fig. l, on a reduce scale.
' A represents the supporting-legs or base of the stove.
B is an upright burner-tube passed through an opening in the top of base A,with its lower end fitting into a T-coupling, I).
G represents the gasrinduction pipe, fitted with a regulating-key, G, and a connectionhose, 0.
D represents an elbow provided with a vertical screw-threaded gasjet, d, which taps T-coupling b, and thereby connects the gaspipe with the burner-tube.
E represents an air-induction tube tapping at one end T-coupling b, and projecting laterally therefrom through opening 6 in the base, with its outer end at a'suitable distance from the stove to supply fresh 'cool oxygen to the burner-tube. The inner discharge-opening of the air-tube is arranged above the discharge.
f f are air inlets or openings in the head I f of the cap. IVhen the cap is drawn outwardly,th e supply of air is increased. When pushed upon the tube inwardly, the supply is correspondingly decreased or cut off entirely, if desired, by means of the outer end of the tube closing the air-inlets f. This adjustment of the cap F adapts the stove to various gas-pressures, and is 'an important feature of my invention.
G is a bell-shape shell or frame, having a perforated bottom, G g, for the escape of the carbonicacid gas which would otherwise accumulate within the shell,to surround the burner and greatly retard combustion.
H H are nuts on the burner-tube,on either side the perforated bottom of the shell,for securing the shell in place.
I represents the burner secured upon the ers the bottom of the vessel placedupon the supporting rack-frame K. The rack-frame removed and replaced, if de is of the usual construction, having a circular rim, L, supplied with legs Z and radial arms 1, as shown in Figs. 2 and 3.
In the operation of my stove the commingling of the gas and cool fresh oxygen brought from a point outside the effective limits or range of the heated carbonic-acid gas insures complete combustion, and an intensely hot violet flame is produced.
I claim i In a gas-stove, the combination, with a burner pipe or tube and anair-induction tube, of a perforated cap, F ff, fitting the .outer end or mouth of the air-tube, and adapt ed to regulate or cut off the supplyof air through said air-tube to the burner, substantially as herein set forth. r
In testimony whereof I have hereunto set my hand.
