UITED STATES PATENT OFFICE.

CHARLES MILLER, OF ST. LOUIS, MISSOURI, ASSIGNOR TO HENRY DANFORD, OF SAME PLACE.

SPIRIT GAS-BURNER.

To all whom it may concern:

Be it known that I, CHARLES MILLER, of the city and county of St. Louis and State ofMissouri, have invented a new and useful Improvement in Spirit Gas-Burners; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawing, making part of this specification, in which- Figure l is a longitudinal section through A A. Fig. 2 is a plain elevation and Fig. 3 is a plan.

Similar letters of reference represent corresponding' parts of the different figures.

The nature of my invention consists in introducing a bent rod into the tube of the lamp, wherein the wick is placed, and in fixing upon the top end of the said rod a valve over the upper end of the wick, and under the orifices, through which the gas issues for combustion. The said valve being applied for the purpose of regulating the flow or supply of gas to the burner, and for the purposevof changing the former size and direction of the flame, it being so ar ranged that it may be open and closed with* facility whereby the light may be wholly extinguished, or otherwise regulated at pleasure.

To enable others skilled in the arts to make and use my invention I will proceed to describe its construction and operation.

K is a plain tube, which may be soldered or otherwise secured to the holder z through which the said tube passes.

b is the burner which fits over the top of the tube K so as to form a tight joint, as at Z).

e e are flanges, upon the side of the burner, for the purpose of heating it, so as to keep up the evaporation.

a a are orifices in the side of the burner, through which the gas issues between the flanges e e.

C is also an orifice in the top of the burner, through which the gas also escapes as in an ordinary burner.

j is a bent rod, one end of which passes up through the tube K, and the other end passes up through the tube holder h as shown. This outside end is secured to the v slide f which is so fixed around the tube K, as to. slide freely up or down as the case may require.

z" is a valve, fixed upon the upper end of the rod inside of the tube, which may be raised to lit into the valve seat z', or lowered so as to close the upper end of the tube K at b, by merely shoving the slide f up or down.

Now suppose the tube K to be supplied with wick, the upper end of which should come just flush with the upper end of the tube, at b, and suppose heat to be supplied so as to occasion the necessary end partition to support combustion at the orifices of the burner and let the valve z" be inthe position shown on t-he drawing, then the burner would produce its maximum of light, and the outline of the flame will be similar to that shown at Fig. 2. Now suppose the valve z" to be shoved up so as to close the orifice C, then all the gas will escape through the side orifices, a a and the fiame will be in the form shown at the sides of the burner at Fig. 2. Now let it be desired to reduce the light to the least possible amount: This is done by shoving down the valve so as to very nearly close the end of the tube, and when it is desired to extinguish the light, the valve is brought down close upon the end of the tube, which also prevents waste from evaporation. It will be seen that the gas in escaping through the side orifices a a, comes into contact with the flanges e e, against which it is consumed; which heats these flanges whereby the evaporating capacity of the burner is increased, which it is one of the objects of this invention to effect. But the chief object sought after here is to regulate the flame of gas through the burner in the manner described.

What I claim as my invention and desire to secure by Letters Patent is- The arrangement' of the valve over the tube and wick for the purpose of extinguishing the flame, or regulating its size and altering its direction in the manner set forth.

CHARLES MILLER.
