AUNITED sTATss VICTOR H. SLINACK, OF PHILADELPHIA,
PENNSYLVANIA, ASSIGNOR 'IO PENNSYL- VANIA GLOBE COMPANY, F PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.
INVERTED IN CANDESCEN 'I LIGHT.
Application led. April 27, 1921.
To all whom t may concer/n:
Be it known that I, VICTOR H. SLINACK,
a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Inverted Incandescent Lights, of which the following is a specification.
The principal objects of the present invention are to provide an inverted incandesA cent light which will give good candle power and avoid iiash-baeks when operated with a relatively large supply of air to the mixture, even in'connection with such gas as is now supplied in many cities; to provide for satisfactorily lighting inverted incandescent lights from pilot lights; and, in general, to improve the eificiency and broaden the application of inverted incandescent lights.
Other objects of the invention will appear from the following description and the invention itself will be claimed at the end hereof.
In the description reference will be made to the accompanying drawings forming part hereof and illustrating features of the invention and in which- Figure 1 is a view, principally in central section, and showing so much of an inverted incandescent light as is necessary for an understanding of the invention, and
Fig. 2 is a similar view illustrating features of the invention.
In the drawings 1 is an inverted burner shown as` consisting of refractory material and as havinga cylindrical internal wall 2. 3 is a tube from which the burner 1 depends by means of the screw thread connection 4, and through which a mixture of air and gas is supplied as is well understood. 5 is an inverted incandescent mantle arranged beneath the burner 1 and supported from some convenient part o-f the fixture 6 as by means of a spider 7 which provides egress for the products of combustion. 8 is a core projecting into the bore of the burner 1 and having a wall 9 which confronts and is spaced from the internal wall 2 vof the burner to provide between said wallsA an annular discharge duct. The core 8 is shown as of generally cylindrical form with fiat ends although, more accurately, it is of the form of a frustum of a cone. Lava is a good material from which to make the core. The lower ends of the core and of Serial No. 464,929.
the burner 1 are shown as arranged in alignment. 10 is an axial pit in the lower end of the core and as shown in Fig. 1, it does not extend through the core but, as shown in F ig. 2,- the pit 10a extends through the core and communicates with the pilot light tube 11. The pilot light tube 11 when of the inverted U-form shown, and arranged through the wall of the tube 3, affords one means for supporting the core. Another means for supporting the core comprises a rod 12 depending from arms 13 carried by a ring 14 arranged in the top of the burner.
This rod 12 is guided centrally of the bore,
of the burner by radial arms 15.
In use the comparatively elongated annular discharge duct or passage between the walls 9 and 2 discharges the mixture of air and gas into the mantle 5 in such a way that the heating iame is appropriately directed and applied to the surface of the mantle for heating it to brilliant incandescence and giving good candle power, and the products of combustion escape upward past the arms 7 and into and through the ixture 6 without unduly retarding the descent of the iiame' by needlessly crossing it. It may be remarked that there is formed in the flame a cone with its apex substantially at the pit 10 or 10a, which cone is of greenish color and indicates that the character and distribution of the heating flame is as it should be. Then the heads of the core are flat they do not direct the combustible mixture unduly towards the walls 2 and hence the mixture escapes from the burner with proper velocity and pressure. By arranging the pilot light inside vof the mantle a comparatively strong pilot flame can be maintained without danger of blackening the mantle.
Moreover the mantle protects the pilot light from drafts which might otherwise blow it out. Again the effects of the explosions which take place when the burner is lighted and extinguished are not felt near or directly under the burner tube in anything like the degree that they are felt in the space between the burner tube and the mantle ring and iixture so that the pilot light is not extinguished thereby. The fact that the pilot light is located near the outlet of the burner tube diminishes the force of such explosions because there is formed less Volume ot explosive mixture, und in this wey the lite ot the innntle is; prolonged. The location oi the pilot light inside ot the mantle und close to the lmrner tuhe insures its relightino' when the nlnin burner being extinguished and insuren iin lightingT the ninin burner when the pilot light in beninr extinguished ond it is desirable that the pilot light he extinguished while the innin burner is burning because the lient ot the ninin burner, heatingl the nos Within the pilot tube, causes the pilot tuhe to @olio up with ent-lion und the like.
