SPECIFICATION forming part of Letters were No. 592,851, dated November 2, i897.

' Application filed December 28,1895. Serial No. 573,121. (No model.)

To aZZ whom it may concern.-

Be it known that I, MAXIMI'LIAN \VENDORF, mechanic, of Frankfort-on-the-Main,Prussia, Germany, have invented new and useful Improvements in Incandescent Lamps, of which the following is a specification. 4

The object of my invention is to provid an oil-lamp by which a flame can be produced capable of making an incandescent body glow as the Welsbach incandescent gas-light does; and said invention consists in the novel arrangement and combination of parts hereinafter described and claimed. For this purpose it is necessary to vaporize thoroughly the oil, petroleum, hydrocarbons, alcohol, or the like, and to mix itwith air in order to get a hot non-sooting flame of about blue color when coal-oil is used. By my invention the heat necessary for this evaporation is yielded at the beginning of the operation by another flame to heat the evaporator. For this purpose there are means provided to vaporize benzin, gasolene, alcohol,or the like by acurrent of air blown through the liquid.

Further, my invention consists in the various means for generating the two flames above mentioned and in the details of construction hereinafter shown and claimed.

In order that my invention may be better. understood, Imake reference to the annexed drawings, showing an embodiment of my invention, wherein Figure l is a vertical section through the lamp. Fig. 2 is a side view of a part of it. Figs. 3, 42, and 5 are detail sectional viewsof the cock on an enlarged scale.

O is the hollow perforated base of the lamp; A, the oil-tank; B, the benzin-tank, located in the interior of the oil-tank.

H is a rubber ball placed inside the lampbase and communicating with the tankB by a pipe h. This pipe communicates with a branch pipe h, having a non-return valve h and being adapted to be connected with a rubber ball H, which is used as an air-pump.

The pipe h terminates inside another larger pipe I), closed at the upper end bythe wall or partition 17 The tank B is filled with cotton-batting and provided with a perforated wall or partom ofv the tank A through said pipe.

tition B. The tank B is fed with benzin by apipe b, extending from the bottom of the tank B to the mouthpiece K. This serves also for the inlet of the oil to the tank A and isclosed by a cover L. This cover isprovided with a conical valve or stopper Z, which fits into the orifice of the pipe Z) and prevents the oil from overflowing if the lamp is inclined, but allows of a communication of compressed air between the tank B and tank A. The continuation I)? of the pipe I) communicates with the space above the partition .B by means of perforations m and also with the benzin-pipe a.

I The pipe at is filled with a wick, cotton, or the like, 'to filter the oil rising from the bot- The casing M and the plug M of the cock have two, ports corresponding to the pipes at and a and leading to the pipes m m, respectively. The ports f and f are so arranged in the plug M that when the port f is turned to almost shut off communication between the pipes at and m the port f will be opened to establish communication between pipes aand m. There are narrow grooves g g on the plug adjoining the openings of the port f, which allow a more delicate regulation than the wide orifice forming the port itself does. There is a scale N, which indicates whether the benzin-conduit alone is open: first, when both conduits are open simultaneously; second, when the oilconduit alone is open, and, third, when both conduits are closed, (0,) and thus the indications on the scale allow the regulation of the oil-flow.

On the tank A are standards D, supporting the vaulted plate G and surrounded by the cylinder Gr, of sheet metal. The plate G is fixed to a tube P, which supports the burner. The burner consists of the bracket E, into which the glass chimney F fits, and of the evaporator R, which is fed with oil from below by the pipe m and which dischargesthe evaporated oil downward by a pipe p with a nozzle p.

The evaporator is placed in the enlarged head P of-the tube P by three arms 0", which rest on the upper edge of a perforated cone t.

Under the cone t is an annular space T for distributing the benzin-vapors entering by' the pipe m.

Q is a cap with apertures q placed on the lower end of the pipe P for admitting air to the vapors discharged by the nozzle 1) and receives such small quantities of condensed oil as may drop.

a is a wire net of conical shape.

8 is a pin 011 which the incandescent m antle S is hung.

The lower part of the glass cylinder F is made conoidal, according to the customary shape of the mantle, whereas the upper part is cylindrical, as usual.

The operation and working of the new lamp are as follows: If the lamp is to be lighted, the handNis set on number l of the scale I and thereby the port f opens communication between the pipes to m. Then by pressing the ball II the ball H is inflated and air driven through the pipes 7L and l) and through the benzin in the tank 13. Benzin-vapors mixed with air pass through the pipes a and m into the annular chamber T and through the perforated cone t to the wire net 1!. If a match is held to the top of the cylinder F, the vapors are ignited and an annular flame generated above the net-wire u. If this flame has burned a quarter or half a minute, the evaporator is sufficiently heated, the hand N is turned to number 2, which establishes communication between the pipes to m, whereas communication between the pipes a m is almost closed. The oil under the pressure of the air enters the evaporator R, the under part of which is below the flame. The evaporator R is made of such size and the walls are sufficiently thin that it receives a sufficient amount of heat by the flame over a to vaporize completely all the delivered oil. The vapors are conveyed from the upper end of the evaporator by the pipe 1), which runs downward and ends in an upward-turned nozzle 1). Here the vapors are discharged and mixed with air and delivered at the wire net to. Here they are ignited by the benzin-flame. Now the hand N is turnedon to number 3 or some other place near it to which the lamp is regulated, whereby the benzin-inlet is cut off and the oil-inlet is opened to the right extent. If necessary, the ball 11 is worked now a little more to fill perfectly the ball II, the contents of which are suflicient to run the lamp for many hours, whereas the operation of the benzin-flame necessitates a comparatively great amount of air.

The shape of the lower part of the chimney F assists in preventing any obnoxious odor and provides a regular ignition of the products of combustion throughout the entire extent of the stocking, whereas the other devices have for their object the generation of a hot, blue, steady, and non-sooting flame. If the flame is to be extinguished, the hand is turned to l. Thereby the oil is cut off and the benzin-flame lighted for the purpose of preventing anysoot being had by the slow extinguishing of the oil-flame and to heat the evaporator R to .the evaporation of the last particle of oil remaining in it.

The object of my invention is not'restricted to the forms and instrumentalities above described; but 7 Vhat I claim, and desire to secure by Letters Patent, is the following:
