EDWARD J. PARSONS, OF MOUNT STERLING, IOWA.

VAPOR-BURNIN G- LAMP.

To all whom it may concern:

Be it known that I, EDWARD J. PARSONS, a citizen of the United States, residing at Mount Sterling, in the county of Van Buren and State of Iowa, have invented a new and useful Vapor-Burning Lamp, of which the following is a specification.

This invention relates to lamps of the type in which a volatile hydro-carbon is vaporzed and the heat from the ignited vapor used to render a mantle incandescent.

One object of the invention is to provide a means for pre-heating the liquid hydrocarbon before it passes into the vaporizing chamber.

Another object of the invention is to provide a means whereby the vaporized hydrocarbon may be kept in a heated state and prevented from condensing.

l/Vith the above and other objects in view as will be hereinafter apparent the invention consists in certain novel arrangements of details, and combinations of parts, hereinafter fully described, illustrated in the accompanying drawings and specifically set forth in the claims.

In the accompanying drawings, like characters of reference indicate like parts in the several views, and: Figure 1 is a perspective view of lamp constructed in accordance with this invention. Fig. 2 is a vertical section through the axis of such a lamp. Fig. .3 is a detailed section showing a mixing valve for use with this type of lamp.

The lamp is suspended by means of a tube or pipe 10 provided at its upper end with a suitable means of suspension as a ceiling plate, hook or the like. This pipe 10 is brazed or otherwise rigidlyv secured to a hollow ball 11, being closed off from the ball by means of a partition 12. Through the partition l2 passes one end of a tubular wire 13. The upper end of the tube 10 is in communication with a suitable source of hydrocarbon under pressure by means of the tubular wire 14.

Brazed or otherwise secured to the ball 11 are a pair of oppositely disposed downwardly curved tubes l5 and 16 so arranged as together to form an arch. The lower end of the tube is valved as indicated at 17 and the tubular wire 13 passes down this tube 15 and through the closed bottom 17 to a needle valve 18 of any preferred form or construction. Upon the lower end of the Specification of Letters Patent. Application filed June 30, 1908.

Patented May 4, 1909. Serial No. 441,185.

tube 15 is mounted an air valve comprising a ring 19, whereon is rotatably mounted a sleeve 20, both body and sleeve being prorided with a series of perforations so that the amount of air admitted may be regulated by turning the sleeve upon the body. Atthe lower end of the tube 1G is a .mixing valve comprising a bell 22, screwed on the tube so that it may be moved up and down by rotating it in one direction or the other, and a fixed nozzle 23 screwed on an elbow 21 mounted on the end of the vaporizing tube 33 hereinafter to be described.

A short tube 26 is brazed or otherwise secured to the hollow sphere 11. and extends downwardly therefrom. Screwed upon the tube 2G is a vertical tube 27 having a reduced lower end, as seen at 28, the said lower end being provided` at its outlet with a suitable screen 29. Upon the tube 2T is mounted a heat bell 30, heilig' arranged to slide longitudinally of the tube and held .in position at any desired point by means of a set screw 3l.

Between the needle valve 1S and the elbow 2li is located a generator tube 33 preferably packed with some such material as asbestos or the like, as at 32. The generator tube 33 is of less diameter than the tube 27 and passes through that tube, being screwed therein. Upon the tube 33 and arranged on either side of the tube 27 is a pair of lock nuts 34. These lock nuts are for the purpose of firmly bracing the tubes 27 and t0- gether.

lvlounted on the reduced portion 2S to the tube 27 is a sleeve carrying an inverted mantle 36.

Depending from the tube 33 is a globe ring 38, a globe 39 being held in a suitable position therein by means of set screws 40. This globe is open at. the bottom to permit any excess of liquid hydrocarbon from accuniulating therein and breaking the globe when the lamp is lighte( A shade supporting ring itl encircles the tube 32 beingl suitably braced by means of inclined arms 42. Carried in the shade supporting ring 41 is a shade 43 which may be of any desired form or color.

lV hen this lamp is lighted it will be noted that the tube 13 is surrounded by a body of hot air and that any liquid hydro-carbon passing through that tube receives a preliminary warming up so that when it passes through the needle valve 18 into the vaporizing tube 33 it is in condition for complete vaporization. By reason of the vaporizing tube 33 passing through the tube 27 there is provided a zone of relatively great heat in the middle of that tube and the vaporizing oi a liquid passing through that tube is accomplished much more effectively than 'where the heat rises freely and unconned. tis further to be noted that by means ot a proper adjustment ot the bell, the tubes may be kept het so that the vaporized hydro-carbon will not condense in either ot them.

It is thus seen by this method of construc tion an extremely ei-icient and useful lamp ot the kind describen is produced and that this lamp is further symmetrical in form and pleasing in appearance.

lt is obvious that minor changes may be made in the form and proportions of this invention without departing from the material principles thereof.

Having thus described the invention, is claimed, is l l. ln a lamp, a vaporizing tube, an arch tube disposed above the vaporizing tube and provided with an unobstructed interior what chamber extending approximately the entire length of said arch tube, a partition between one end of the arch tube and vaporizing tube, a mixing valve between the other end of the arch tube and the vaporizing tube, a supply pipe held in the arch tube in communication with the vaporizing tube, a mantle, and a tube extending from the arch tube to the mantle.

Q. In a lamp, ahorizontal vaporizing tube, an arch tube disposed above the vaporizing tube and provided with an interior unobstructed chamber extending the entire length of said arched tube, a partition between one end of the arch tube and the vaporizing tube, a mixing valve between the other end of the arch tube and the vaporizing tube, a valve controlled supply pipe held in the iirst mentioned end of the arch tube in communication with the vaporizing tube, a mantle, and a vertical tube extending from the center of the arch tube to the mantle.
