VAPOR-BURNING- LAMP.

' Specification of Letters Patent.

Applioationfiled AugustS, 19 08. Seria1No.4e6,65o.

My invention has relation to improve ments in vapor-burning lamps; and it consists in the novel details of construction more fully set forth in the specification and pointed out in the claims. i

In the drawings, Figure 1 is a side elevation of my improved lamp, showing the parts tion on the line 22 of Fig. 1; Fig. 3 is an enlarged side elevational detail showing the connection between the main supply-pipe and the burner-pipe; Fig. 4 is a cross section on the line 4.-4: of Fig. 3, Fig. 5 is an enlarged sectional detail showing the manner of mounting the feed-valve in the tee interposed between the outer or upper and inner or lower sections of the burner pipe; and Fig. 6 is a detached view showing in perspective the removable draft-shield.

The object of my invention isto construct a vapor-burning lamp to the burner of which the mixture of air and hydrocarbon is supplied from a source removed a suitable distance from the lamp, the present invention being restricted to details which are independent ofthemeans by which the mixtureis produced. In other words, the present lamp is devoid of any so-called mixing chamber characteristic of the majority of vaporburning lamps.

A further object is to provide special means of effecting a connection between the burner-pipe of the lamp and the main supply-pipe; to provide a special construction of feed-valve; to provide special means of securing the draft-shield, and to provide further and other details the advantages of which will be apparent from a detailed description of the invention which is as follows:

Referring to the drawings, 1 represents the upper section of the burner-pipe, the base thereof carrying a tee 2 serving as a casing for the feed-valve 8, the lower leg of the tee being screwed to the upper end of the lower section 1 of the burner-pipe as shown.

all assembled; Fig.2 is a vertical secalsoserving to engage inner face of the out-door use the shield S is generally em- .ployed;

screw serving as a valve may freely rotate.

The upper end of the section 1 is itself screwed into the hollow boss 4 formed in the crown of the hood H, the lower end of the pipe serving as a burner, about the flame of which may be suspended any form of incandescent mantle Mas shown. The hood H is preferably domeshaped, being provided with a series of peripheral draft openings O, at points about midway the height thereof, the base of the hood serving to support the draft-shield S by means of a series of screws 5, 5, the inner ends of the latter the upper flange of a globe G where occasion arises to employ a globe. grits shown in the drawings, the draft shield. comprises an outer basal flange a, an

inner terminal tapering or conical mouth 7) and an annular or c lindrical intermediate or connecting portion 0 through which the screws 5 pass, and which telescopes with the base of the hood H. For

for indoor use it may be removed, leaving the screws 5 to support the globe G if desired.

The tee 2 uniting the upper and lower sections 1, 1- of the burner-pipe serves as a casing for the rotatable'feed-valve 3, the

latter comprising a cylinder having a through passage-way p which may be turned to register with the passage way i of the pipes 1, 1; or turned out of register as obvious.

One of the terminals of the'h orizontallegs v of the tee 2 is closed, the wall at that end serving as a bearing for the screw-spindle 6 of the valve, said spindle having a threaded portion engaging a screw-threaded socket in the adjacent end of the valve whereby the latter can be secured in position within its easing, the unthreaded portion of the spindle about which the This rotation is accomplished by an arm or lever 7 projecting from the periphery of the valve at the opposite end thereof, the casing having formed thereon a terminal recess 1 to allow for the necessary play of the arm, the swing of the arm (and rotation of the valve in consequence) being limited in either direction by the shoulders s s defining the limits of the recess referred to.

The upper end of the pipe-section 1 terminates in a socket 8 having flanges 8' for securing the same to the ceiling, the interior wall of the socket being formed with a necessary, and when neither are required both may be removed withoutmade are old longitudinal groove 9 to engage a corresponding tongue or seam 10 formed in the main supply pipe 11, whereby a connection between said pipe and socket is readily effected, a band of solder 12 being subse quently passed about the seam between the pipe and each end of the socket. The tongue and groove connection between-the parts 8 and 11 insuresagainst any possible twisting or displacement of the parts since it acts as a perfect lock. Of course the positions of the tongue and groove may be reversed as is obvious.

As seen from the drawings, the conical mouth of the draft-shield which encompasses the pipe 1, is at the same time sufiiciently spaced apart from the hood, so that the products of combustion may freely circulate outwardly through the openings 0 formed in the hood. The shield too prevents any drafts from interfering with the flame, such drafts being deflected by the conical inner portion and caused to escape through the openings 0. The arrangement resorted to for securing the shield at the same time serves to support a globe when globe nor shield disturbingother portions of the lamp. So too, the globe may be removed Without the shield, and vice versa.

A decided advantage follows from the manner of assembling the parts as herein indicated, and that is, that once the pipe sections 1, 1 are screwed into position on the hood, all parts are in their proper relation without further adjustment. This insures a uniform posit-ion for the mantle; and the lamp may be assembled by even an unskilled mechanic. Such features as may be illustrated but to which no reference is and require no description in th1s connection.

Having described my invention what I claim is:

1. In combination with a burner-pipe, a hood located thereon at a point removed hood located thereon at a from the burner end of the pipe, a feedvalve in the pipe, a draft-shield having an inner tapering mouth encompassing the illner end of the pipe and spaced a suitable distance from the hood, an intermediate portion of the draft-shield telescoping With the free end of the hood and supported thereby, and an outer flanged portion of the draft shield projecting beyond the hood, substantially as set forth.

2. In combination with a hood having a closed crown and open at the bottom, a burner pipe composed of two sections united at the crown and extending into and out of said crown, a tee at the juncture of the sections located adjacent to and exterior to the hood, one of the terminal walls of the horizontal. member of the tee being closed, a r0- tatable valve mounted in said horizontal. member, a screw spindle connecting the valve to the wall aforesaid, an arm carried by the periphery of the valve at the opposite end, the casing member being suitably recessed to permit of the necessary oscillation of the arm, substantially as set forth.

In combination with a burner-pipe, a point removed from the burner end of the pipe, a feedvalve in the pipe accessible from a point outside the hood, a draft-shield having an inner conical mouth encompassing the inner end of the pipe and spaced a suitable distance from the hood, an intermediate annular portion of said draft-shield telescoping with the free end of the hood, and an outer flanged portion projecting beyond the hood, and securin screws passed through the hood walls and said intermediate portion of the draft shield, the inner ends of the screws being available for supporting a globe, substantially as set forth.

In testimony whereof I afiix my signature in presence of two witnesses.
