Speciiication forming part of Letters Patent No. 115,350, dated May 30 1871.

To all whom it may camera:l

Be it known that I, GEORGE T. PARRY, o

the city and county of Philadelphia, in the i State of Pennsylvania, have invented a new ,and ImprovedVapor-B urner; and I do hereby declare that the following is a full, clear, and

exactdescription thereof, reference being had to the accompanyingdrawin g making part of this specification, in which- Figure 1 is a diametrical section through the improved burner. Fig. 2 is a sideview of the .brnen Fig. 3 is a horizontal 'section through the cone top taken above the perfora-ted diaphragm therein. t l

Similar letters of reference indicate corresponding partsin the several figures.

This inventionrelates to burners which are designed for burning the `vapors ofv light hydrocarbon fluid. The nature Yofmy invention consists in the combination of a vertically-adjustable burner-tube, a stationary internal stem, and regulating-valves, whereby the ow of the iiuid into the burner can be nicely regulated, or, if desired, entirely cut oli', as will be hereinafter explained.

To enable others skilled in the art to understand my invention, I will describe its construction and operation.

In the accompanying drawing, A represents the burner-tube, which is beveled on its lower end, screw-threaded, and fitted into an elbow, D. This elbow has a small aperture, t, leading into its verticalportion, and at s s is a` seat for receiving the lower beveled end of tube A when it is desired to cut off the ow of burning-fluid intothis tube. The tube A isl verticallyadjustabla and, at the upper end of its elbow D, it is provided withua packing-box l `or cap, g, shown in Fig. l. The upper end of thetube A enters and is secured tightly into an inverted conical frustum, B, which has sei curedinto it, on thepupper terminus of said tube, a horizontal perforated diaphragm, h.

lBeneaththe frustnm B the external surface of the tube A is screw-threaded, and on this screw-threaded portion an adjustable collar, C, is applied andused for closing or partially `closing orifices om. lising from the elbowD through the center of the tube A, and permanently secured to said elbow, is a stem, G, which terminates at a point just below the air- `inlets a a in a conical valve, s', which is adapted to a valve-seat, n, in tube A. All that portion of the burner above the valve-seat n forms a vapor-receptacle; and all that portion vof the tube A below the valve-seat receives the stem G and a porous packing, which latter will cause the ascent of uid through valve-open r ing n into the vapor-receptacle, where it is volatilized and burned'at the apertures b b.

To light the burner the tube A is slightly u rotated about its axis, which causes it to rise and open the valves above and below, and thus form acommunication between the vaporchamber above the valve-seat n and the fluid below it. A light is then applied to the frustum, and when the vapor therein` is sufficiently expanded it will issue from the apertures b b and ignite. The heat which is now generated by the burnerfjets will continue to volatilize the iluid and keep up a constant supply of vapor. The collar Gis adjustable for allowing more or less air to enter the vaporizing-chamber and mix with the vapor therein. The tube A is adjustable for regulating the iiow of fluid into the burner or for entirely closing the inlet-passage t.. The perforated diaphragm h on top of the tubeA allows the vapor to pass up and then n own through it. This diaphragm becomes h' ly heated, and assists in the rapid conversion of the vapor into gas; and when the light is extinguished the diaphragm will retain for a long time its heat, which will generate gas in the frustum and render the burner easily relighted.y j

Havin g described my invention, what I claim 1s- The adjustable burner-stem A, the stationary ysolid valve-stem G, `and the valve and valve-seats n s, combined to operate substantially as described.
