Specification of Letters Patent.

Application filed April 26, 1910.

Patented Oct. 18, 1910.

Serial No. 557,633.

To all whom it may concern:

Be it known that .l, Amman H. S. SWAN, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful lmpioven'ients in Alcohol- Vapor-Lamp Burners; and I hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of the specification, and to the reference numerals marked thereon.

My present invention has for its object to provide a burner for lamps adapted particularly for generating gas from light hydrocarbon oils, or alcohol, whereby the volume of the gas generated may be varied according to the intensity of the flame desired.

My invention has for its further object to provide a suitable supply valve whereby the flames of the main and pilot burners may be simultaneously adjusted to vary the intensity of the latter in proportion to the size of the former.

To these and other ends the invention consists in certain imprmei'nents and combination of parts, all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawings: Figure 1 is a vertical sectional view of a lamp provided with a burner showing one embodiment of my present invention; Fig. 2 is an enlarged sectional view showing the regulating valve in the open position; Fig. 3 is a horizontal sectonal View taken on the line 3* 3* in Fig. 1, and Figs. 4 and 5 are sectional views showing modified constructions.

Similar reference numerals in the several figures indicate similar parts.

My present invention relates particularly to burners adapted to burn the gas supplied thereto from a suitable generator, preferably a tube 1, closed at its upper end, as indicated at 2, and containing a wick 3, absorbing the oil from the bottom of the font 4.

The burner is supported upon the wick tube, shown in Fig. 1, and comprises the annular ring 5 provided with flame orifices (l in its upper surface, and supported on a plurality of tubes 7, which conduct the gas thereto from the main gas collecting chamher '8. The latter is constructed in the form of a ring which is rigidly connected to the wick tube and surrouiul'ing the latter is a similar tubular ring 9 supporting the pilot flames, which are emitted from small orifices l0 situated at various points on said ring 9. The upper surface of the ring 9 in the areas surrounding the orifices 10. is depressed slightly at an angle, as indicated at 11, to cause the flames ejected from the orifices to impinge against the wall of the wick tube for the purpose of maintaining the tube heated to the temperz'iture necessary to supply the quantity of gas required by the main burner 5 according to the varying conditions under which it may be desired to operate it.

The valve for controlling the flow of the gas to the chambers 8 and 9 is arranged be neath these rings and comprises the body or casing 12 rigidly secured to the wall of the wick tube and provided with a central aperture 13 communicating with the interior of the tubeand with laterally extending passages 14 and 15 leading from the central aperture into the chambers 8 and 9 respectively. The aperture 13 comprises two portions of unequal diameter and from these portions lead the passages 14 and 15. In the preferred construction of the valve the aperture 18 is circular and at its inner end the walls thereof are cylindrical continuing outwardly a short distance from the wick tube to the point 16 in rear of the passage 14, and from said point the aperture is made conical, the diverging walls thus formed extending rearwardly beyond the passage 15. Fitting the aperture in the valve easing, thus formed, is a valve head having the conical body portion 17 beyond which pro trudes the cylindrical tip 18, said head being provided wit-h the longitudinally ex-- tending passage 19, the outer extremity of which extends laterally and opens at the part indicated by 20. The latter and the inner end of the portion 18 are so proportioned relatively to each other and to the positions of the passages 14 and 15, that when the valve head is closed both the said passages will be cut off, but when it is adjusted rearwardly the passage 19 will first establish commui'iication between the passages 13 and 15 before the passage 14 is uncovered. This enables a sufiicient quantity of gas to flow from the generating chamber to the supplemental burner to support the pilot light flames before the gas is admitted to the main burner. After the main burner has been in operation this arrangement permits the supply of gas to the main burner to be cut oil and the burning of the pilot lights to be continued, if so desired, with sufficient intensity to maintain the generation of the small amount of which they require.

The outer end of the valve casing is fitted with the packing 21 held in place by the usual gland nut 22 having an interior thread, providing the means for longitudinally adjusting the valve head, the latter being operated by the rotation of the stem 23 attached thereto carrying a suitable operating handle, not shown.

In operating the burner heat from some exterior source is applied to the wick tube for a brief period until generation of gas in the upper end thereof has conn'nenced. The valve stem 23 being rotated will retract the head 17 causing its larger body portion to be moved out of engagement with the corresponding walls of the valve casing, thus providing an annular chamber 2% through which the gas generated in the wick tube may pass from the port 20 into the passage 15 and thence to the pilot light orifices 10. Now, if the burner is not required for immediate use the pilot lights may be allowed to burn as long as desired. The size of the passage 2 f may be varied by the adjustment of the valve head and thus the size of the pilot flames controlled, and when it is desired to use the main burner the valve head may be retracted until the extremity of its tip 18 uncovers the passage 14 to the desired extent, and during this adjustment it will be noticed that the quantity of gas supplied to the pilot lights will be increased, their intensity being regulated in accordance with the volume of gas admitted to the main burner.

In Fig. 415 the valve body is shown with the relatively large and small portions 30-31 of its central chamber both made cylindrical and the valve head made to reciprocate therein into and out of cooperating engagement with the two outlet pas sages 14 and 15 While I prefer to make the larger portion of the aperture in the valve casing conical, as before described, these parts may be an ranged as shown in the modification illustrated in Fig. 5. In this view the enlarged portion is represented as an annular recess 32, the forward shoulder 33 of which cooperates with the outlet port of the passage 19 in the valve head l7 when the latter is advanced or retracted by itsrotary movement in the valve casing 12*.
