UNITED STATES PATENT OFFICE.
JOHN WALSH, OF LONDON, ENGLAND.
BURNER AND GLOBE.
SPECIFICATION forming part of Letters Patent No. 614,148, dated November 15, 1898.
Application iiled December 27, 1897. Serial No. 66 3,801. (No model.)
To @ZZ whom it may concern.-
Be it known that I, JOHN WALSH, a subject of the Queen of Great Britain, and a resident of London, England, have invented certain new and useful Improvements in Burners and Globes, of which the following is a specification. Y
In order to magnify the light, or to better direct and utilize the same, or to obtain in effect more light from a given quantity of gas, oil, or other combustible illuminant or electric or other illuminating power, I combine with a globe constructed as hereinafter described a burner or light-giving device also constructed in the manner hereinafter set forth. p
Reference being made to the annexed drawings, Figure lis a section through globe and burner for gas. Fig. 2 is a plan thereof. Fig. 3 is a similar section through the globe and fitting for electric incandescent lamps. Fig. 4. is a similar section of globe and burner for oil-lamp. Fig. 5 is a similar section of globe and burner for gas-light in which an incandescent mantle is used.
The globeAconsists of or comprises an annular lens B-that is to say, the globe is constructed so that the glass is annularly thickened or provided with a similar chamber for water or other liquid in sucha manner that its section is either double convex or plano-convex in appearance, such sectionbeing taken upon any planecontaining the axis of the burner or equivalent fitting. The medial plane of the lens may be an inverted cone, as in Fig. l, which is necessary or desirable from manufacturing considerationswhen the lens is double convex, or a cylinder, as in Fig. 4t, when the lens is plano-convex, the one or other form being used according as the light is to be directed downwardly or horizontally and according to the nature of the illuminant or illuminating power. This medial plane is represented by the dotted line a b, Fig. l, or by the plane side ct b of the lens, Fig. 4.
The burner or light-emitting fitting C is so made that the flames or light-emitting filaments or surfaces D are in the form of straight shafts of approximately equal light-emitting power throughout their length, such shafts being preferably directed parallel to the said medial plane of the lens at its nearest part, this plurality of shafts being equidistant around the burnerthat ispto say, it is an essential feature of this invention that the lightjshould not be employed in the form of a sheet of flame, but should be broken up into a plurality of independent and separated pil` lars or shafts of light. Where, as with the use oft-an incandescent mantle, it is not desirable to use separate mantles of thin elongated form, the single central mantle may beemployed; but its light-emitting power is split up into a plurality of strips or shafts either by the use of non-combustible strips of .asbestos or the like or by use of an opaque screen surrounding the mantle and having slits therein for the passage of the rays.
In gas-burners or jets when used for this invention a plurality of holes or orices is employed to produce a plurality of straight and narrow flames. Electric incandescent lamps arealso so made that the filaments lie in straight lines throughout the greater part'- The combination with a transparent globe Witnesses A. E. MELHUIsH, RA. KOEHLER.
