ASSIGNOR TO THE CINCINNAT CORPORATION OF OHIO.
. AIEBOPLANE LAMP.
Application filed Ital-ch 18, 1925. Serial No. 16,546.
My invention relates to lamps and is partlcularly directed to a type of lamp adapted to be used on aeroplanes and other moving bodies where it is desirable to have a structure which offers small resistance to the air and provides great lighting area.
One object is toprovide a lamp having a transparent, translucent or light permeable material globe so shaped as to ofier a minimum of air resistance.
Another object is to provide a lamp which can be easily made and quickly assembled.
Otherobjects and certain advantages will appear from the description of the drawing, in which:
Figure 1 is a lamp.
Figure 2 is a bottom plan view of the body with the base removed.
Figure 3 is a section on line 33, of Figure 1.
I provide an elongated egg shaped or irregularly elliptical globe 1, the forward end 2 thereof tapering more gradually than the opposite end 3. This shape is termed streamline in the art. The exact curves therefor are worked out mathematically for the intended speed of the vehicle in which the light is mounted.
The globe 1 comprises two sections 4, 5, the ends of which meet in a vertical longitudinal plane. Section 4 has an ofi'set portion 6 formed around its edge, said portion being offset the thickness of the material. When the opposite section 5 is placed thereagainst, theotfset portion 6 overhangs the plain edge 7 of the section 5 thereby providing mating edges and preventing the entrance of moisture or dust. K
In the center of the bottom of the globe and at its widest part is a circular aperture 8. The aperture is formed by bending the material of which the globe is'formed around a circular metal ring 10. The ring 10 is placed on the inside of the globe and the material bent or molded upwardly on the inner side of the ring and then on the top of said ring a distance suflicient to insure rigidity.
The ofiset portion 6 is cut away near the aperture 8 far enough so as not to provide an irregular bearing for the globe 1 on the base 11 of the lam The globe 1 is suitlongitudinal section of the ably fastened to the base by screws or bolts 12 entering into the ring 10.
The base 11 is of hollow structure having upper and lower flanges 1-3, 14. respectively, the upper flange 13 shaped to fit the contour of the globe 1 and the lower 14 having apertures for bolts 15 holding the base 11 to a base plate 16.
An incandescent lamp 17 and socket 18 of standard make are used for illumination and extend into the globe through aperture 8. The socket is rigidly clamped in position by means of a flange 19 thereon which is clamped between the base 11 and base plate 16.
The globe 1 is composed of any color or composition such as will give the desired translucency or transparency, non-inflammable material being preferable. Making the globe substantially in halves permits more economicalmethods of manufacture and provides a structure which can be shipped unassembled with little danger of breakage.
The streamline shape offers as small as possible anamount of air resistance and the transparent or translucent material provides a maximum of lighting area.
7 Having described my invention, I claim:
1. A lamp, comprismg, an elongated twopiece globe of translucent material, a base therefor, a flange on said base shaped to correspond to the curvature of the globe and to fit about an aperture in the globe side, a ring mounted on the inside of the globe and lying around the margin of the aperture, said ring formed to correspond to the shape of the base flange and nesting therein with the material of the globe clamped between the base flange and the ring, and a light source mounted within the base and extending upwardly through the aperture into the globe at right angles to the longitudinal axis of the globe.
' 2. A lamp, comprising, an egg-shaped two-piece globe of light permeable material, a cup-shaped base, a flange on said base corresponding in shape to the curvature of the globe side and fitting thereagainst, a ring mounted on the inside of the globe and lying around the margin of an aperture between the base and globe with the material of the aperture edge drawn around the inner edge of the ring, said ring shaped correspond tothe curvature of the globe, a light source extending from the base into the globe, and adapted to support the globe and a light means for securing the globe aperture marsource within the globe, and means associat- 10 gin portion and ring to the base flange. ing said globe sections, said ring and said 3. Alamp,comprising,astreamlineshaped base securely together. 5 globe of light permeable material, said globe In witness whereof, I hereunto subscribe formed by the mating of two sections, an my name.
