GAS osi-VAPOR LAMP.

SPECIFICATION forming part of Letters patent No. 728,265, dated May 19, 190s Application filed August 15, 1902. Serial No. 119.701. (No model.)

To all whom it may concern/: q c

Beitknown that I, ARTHUR MENDEga citizen of the United States, residing in the city of New York, in the county of New Yorkand State of New York, have invented cer-tain new and useful Improvements in Gas or Vapor Lamps, of which the followingis a speci- `fcation.

This invention relates to gas or `vapor xo lamps; and it consists substantially in the improvements hereinafter particularly described.

The invention has reference more especially to that class of gas or vapor lamps in which I5 ordinary gas is combined with atmospheric air aud consumed at one or more. burners either for heating or illuminating purposes; and one of the principal objects of the invention is to provide a gas or vapor lampof this 2o kind in which perfect admixture ofgas and air is had, resulting in a clear flame of great brilliancy and intensity.

A further object of the invention is to provide a gas or vapor lamp which is simple in z 5 the construction and organization of elements or parts thereof and one which is effective and reliable in use or operation. v

The above and additional objects are attained by means substantially suchv as are illustrated in the accompanying drawings, in which-u Figure l is an enlarged perspective` View,l

in, part verticalsection, of the gas-and air burner employed in my improved gas or vapor lamp, and Fig. 2 is a side View of .the`

lamp, on reduced scale. Fig. 3 is aside view of the main and auxiliary or pilot burners shown in'Fig. 2. Y

Before proceeding with a more-detailed de'- 4o scription it may be stated that my improved'- gas or vapor-lamp comprises a specially-con',-

structed fitting, in the main body of which' works a gas-admission cock or valve having a lateral port which may be made to register.'

4; with a port communicating with the interior of a branch of the fitting, in which branchis screwed or otherwise fastened an end of a gassupply pipe leading from any point of support therefor. Secured in the upper end of 5o the mainbody of the fitting is a burner-tube having at the upper end thereof preferably duplicate main' burners for the combined gas and air, the said'burner-tube having air-inlet openings and otherwise specially constructed, as hereinafter specifically described. Leading preferably from thesides of4 the branch of the fitting are duplicate small gas-tubes extending upwardly through and slightly above the main burners', the upper ends of which tubes constitute pilot or ever-lighted 6c burners by which ignition of the gas mixture is effected at the main burners Whenever the gas-supply is turned on-to said. main burners. The gas-ad mission cocker valvelis formed with a port for the operative end of a needlevalve for controlling the gas-supply to the burner-tube, the said .gas-admission cock or valve being of special embodiment, and the saidl needle-valve isi"V provided with special means for adjusting or regulating the same. 7o The interior of said burner-tube'constitutes practically a mixing-chamber forthe gas and air, and inclosing theburner-ittingis a cage which supports an ordinary glass globe havling a reflector at the top, and-up,o'n which 75 globe is a chimney or'tube surmoupted byanother reiiector, vall as will hereinafter fully appear. j

,Specic referenceY beinghad to the accompanying drawings by the desiguatingcharac- .8O i 'ters marked thereon,-A represents a speciallyconstru cted fitting, the body a of which is hollow, as shown, and theinner surface of which is conical or tapering upwardly, as indicated at b, said tting having a lateral upt'urned 85 branch c, communicating with the interior .of body ct by means of aportd i-n the side of the latter. Screwinginto or-otherwise ltting the end of said upturned branch c is the lower end of an ordinary gas-supply pipe e, which may 9o lead from a ceiling .or vother support, and

snugly fitting within the hollow body a of Ythe fitting A is a conicalxcock or 4plug-Valve B, which is also preferably hollow,.as shown,

and is formed with a lateral port f, which may be carried into and out of register. with port d, as desired, by simply turnin'gthe'fcock or valve B in one direction"orthe'other, the said cock or valve being formed or provided at its lower end with a shank or stem g, which works rco or turns i-n an opening in a nipple or cap h, which is threaded externally to screw into the lower end of the hollow body a of the fitting, as shown, and surrounding the said shank or stem is a spring exerting its tension between the said nipple or cap and the lower end of the said cock or valve to constantly urge the latter' upwardly within the said hollow body, so as to prevent leakage of gas from the fitfing. The pressure of said spring may beincreased or diminished by properly adjusting the nipple or cap h, as is apparent. The said shank or stem g is provided with a central longitudinal opening, through which Vpasses from beneath a needle-valve C, the upper pointed end m of which regulates the passage of gas or vapor through a port n in the upper end of cock or valve B, the sides of said port being also conical. (See Fig. l.) The lower portion s of said needle-valve is threaded to fit a threaded opening s in the shank or stem, the latter being formed or provided at its lower end with a key 10, which may be taken hold of by the hand for the purpose of turning or manipulating the cock or valve B to turn on and shut off admission of gas to the interior thereof. The lower end of the needle- Valve is notched at u to receive the end of a screw-driver or other implement which may be conveniently employed to turn said needle-valve when desired to adjust the same.

The upper end of the body a of the fitting A is recessed and interiorly screw-threaded at u to receive the corresponding exteriorlythreaded lower end of a burner-tube D, provided around its lower portion with air-inlet openings w, the said tube being surmounted by preferably duplicate main burners E E and the interior thereof constituting a mixing-chamber for the gas and air passing to said burners. The location of the gas-exit port n in the end of cock or valve B is such with respect to said air-inlet openings that the force of gas issuing from said port induces currents of air to enter such openings and mix with the gas in a manner quite apparent. Each of the said main burners is provided with a lateral projection a; for receiving the lower end of the supporting-rod y of an ordinary incandescent mantle ll, the said rods being secured in place by set-screws z, as shown.

Fitting in a hollow plug l2, projecting from each side of the upturned branch c of the fitting A, is the lower end of a small gas-tube ll, said tubes leading upwardly throughv and above the main burners from beneath, as shown, and the upper ends 16 thereof constituting auxiliary or pilot burners which may be kept constantly lighted to serve to ignite the gas mixture at said main burners whenever a supply of gas is caused to flow thereto. Said auxiliary or pilot burners are constantly supplied with gas frornthe branch c of the fitting, which branch, as is understood, is in open communication with the gas-supply pipe e. Preferably I employ a valve 20, working in each of said plugs l2, for cutting oil the passage of gas to the said pilot or auxiliary burners, if desired.

Screwing upon the lower externally-threaded end 25 of the body ct of the fitting A is a collar or ring 26, between the upper edge of which and a shoulder 27 on the body is clamped a cage or holder 30 for an ordinary glass globe 32, the lower edge of which fits within a ring 33 on the upper edge of said cage or holder and is fastened by a set-screw 34, the cage or holder being formed, preferably, all around wilh air-inlet openings 35. Located at the upper part of the globe is a refiector 3S, which may be integral with or attached to a chimney or flue 40, which also is preferably surmonnted by a reflector 4:2, suitable means 43 being provided above said refiector whereby the lamp structure may be suspended from any suitable support therefor. As thus constructed and organized it will be seen that my improved gas or vapor lamp is simple and effective and also that the same may be manufactured at comparatively small cost.

It is apparent that l am not limited to the precise details of embodiment herein illustrated and described, since departures may be made therefrom coming within the scope of my invention.
