HENRY BRAGG, or; CLEVELAND, oI-I1o.

PETROLEUM-FLUID BURNER.

SPECIFICATION forming part of Letters Patent No. 505,417, dated September 19, 1893.

Application filed December 30, 1891. Seria1 No. 416,599. (No model.)

To all whom it may concern.-

Be it known that I, HENRY BRaGG, a citizen of the United States, and a resident of Cleveland, in the county of Ouyahoga, State of Ohio, have invented certain new and useful Improvements in Petroleum-Fluid Burners, of which I hereby declare the following to be a full, clear, and exact description such as will enable others skilled in the art to which it appertains to make and use the tions of carbonaceous matter thereupon.

My invention further contemplates certain improvements in the construction of such burners whereby certain important advantages are attained, all as will be hereinafter fully set forth.

The novel features of the invention will be carefully defined in the claims.

In order that my invention may be the better understood, I have illustrated in the accompanying drawings a burner embodying my improvements, in which drawings-- Figure 1 is a vertical axial section of the burner and Fig. 2 is a side elevation of the same. Fig. 3 is a detail perspective view of the burner support detached, and Fig. 4 is an enlarged perspective detail of the valve for governing the outflow of the fuel.

In the views A is the shell of the burner, constructed in two sections each of which is provided at the center of its lower edge with a projecting perforated lug, hinged at a between two lugs or eyes 1), formed at opposite sides of the ends or arms of the base support ing frame 13, as clearly seen in Figs. 2 and 3. This shell A when closed together as seen in Figs. 1 and 2, is of a conical form and incloses the pan D mounted on the frameB and having a central interiorly screw threaded lug or boss D, adapted to receive the screwthreaded lower end of the pear-shaped generating chamber or vaporizer C, said shell being provided at opposite sides with perforations A, through one of which protrudes the oil supply pipe I, as seen i'nFig. 1. The upper end of the vaporizer C is exteriorly screw threaded at c, and on it screws the interiorly screw threaded collar e, of the open conical frame E, which is provided at its upper end with aringe, the upper face of which is grooved around its outer'side to receive the lower edge of the fun H, having a polygonal upper end or head and provided with a central bore and a raised valve seat h, at the upper end thereof, in which bore is arranged the valve stem W, of a valve k fitting in said valve seat as seen Fig.1.

Formed diametrically through the lower screwthreaded portion of plug H is a slit or 'SELWQOHt h, as seen in Fig. 4, the upper end of said slit projecting, when the plug is screwed into the mouth of the vaporizer, slightly above the edge of the same, whereby outlets are formed for the vapor about the sides of said plug, as will be readily understood.

Formed on the lower portion of the vaporizer C is an annular heating pan L, provided with a projecting circumferential flange Z. This flange is of a less diameter than the internal diameter of the annular chamber of the pan D, as clearly seen in Fig. 1, whereby any oil or fuel which may drip therefrom will fall into the said annular chamber. The said pan D has, in addition to said annular central chamber, four auxiliary chambers d, in the form of equally spaced segments, being in communication with the said annular chamber through recesses (1, formed in the upper portions of the walls thereof, as clearly seen in Fig. 3.

The operation is as follows:-The oil being admitted to the vaporizer overflows therefrom through the slits h in plug H, running down around the sides of the vaporizer into IOC the pan L, from which it overflows over flange linto the central annular chamber of pan D. Then this central chamber shall have become almost filled with the oil, the chambers d, (1 will commence to fill by the overflow from the recesses 01. Thus it will be seen that the oil for the initial heating is distributed and burned over a Very large surface, whereby its combustion is assured. The vaporizer having become sufficiently heated, the oil therein is vaporized and passes in this form through the slits h and is ignited, passing up through the cone F and being projected out over the upper edges thereof by the spreader G under the draft through the cone.

The function of the valve it is to provide a regulator for the outflow of fuel from the vaporizer. It will be understood that any ordinary or normal outflow from the vaporizer will be by way of the slits h, but in case the pressure in the vaporizer should rise above the normal, the excessive pressure will raise the valve h from its seat, and the gas will escape by way of the axial bore of plug H, also.

Having thus described my invention, I claim- 1. In a hydrocarbon burner, the combination with a frame, of a vaporizer mounted thereon, and a shell inclosing said vaporizer, said shell being in two sections, each of which is hinged to the frame, substantially as set forth.

2. In a hydrocarbon burner, the combinain said vapor outlet with its slits communicating between the interior and exterior of said vaporizer, said plug being also provided with a central bore and a valve seat, and a valve adapted to fit said valve seat, substantially as set forth.

4. In a hydrocarbon burner, the combination with a frame, of the pan D, mounted thereon and provided with a central interiorly screw threaded boss, the vaporizer having a supply pipe and an outlet and being provided with a screw threaded lower portion engaging said boss of the pan, substantially as set forth.

5. The combination in ahydrocarbon burner, of a vaporizer having a supply pipe and a reduced and screw threaded upper end forming a vapor outlet, of the frame E having a screw threaded collar engaging said screw threads on the vaporizer, said frame being provided with a ring e at its upper end, and a cone F mounted on said ring, substantially as set forth.

6. The combinationin ahydrocarbon burner, of a vaporizer provided with'a supply pipe and having an interiorly and exteriorly screw threaded upper end forming a Vapor outlet, the diametrically slitted plug H arranged in said upper end of the vaporizer with its slits communicating between the interior and exterior thereof, said plug being further provided with a central bore and a valve seat,

the valve fitting said seat and having a stem arranged in said central bore of the plug, the frame E having an interiorly screw threaded collar at its base, said collar engaging the exterior screw threads of the vaporizer, and the cone F mounted on said frame, substantially as set forth.

HENRY BRAGG.
