'FREDERICK SHANNON MILLS, or `Los ANGELES, CALIFORNIA.

LAMP CONSTRUCTION.

v To all whom it may concern:

Be it known that I, FREDERICK SHANNON MILLS, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements. in Lamp Constructions, of which the Vfollowlng is a 'specicatiom My object is to make an improved lamp construction, especially for lamp posts, and my invention consists of the novel features herein shown, described and claimed.

Figure 1 is an elevation of a lamp embodying the principles of my invention, mounted on a post; the lower part of the post being broken away.

Fig. 2 is a sectional elevation on an enlarged scale. y

Fig. 3 is a plan of the refractor.

Fig. 4 is a fragmentary cross sectional detail of the refractor.

lamp socket 1 is centrally mounted through a head 2 upon the upper end of an electric conduit 3; the electric wires 4 run ning up through the4 conduit 3 to the filament of a bulb 5.

The head 2 is fixed in the upper end of a lamp post 6, said head being a iiat circular plate having ventilator openings 7, and having a seat 8 in its upper face concentric with the socket 1.

A supporting fitting 9 is screwed upon the upper end of the post 6 and has an internal screw thread 10 in its upper end.

A funnel shaped refiector 11 tits upon the seat 8 and extends upwardly around the bulb 5 to a point above the top of the bulb 5. A funnel shaped translucent globe 12 lits the screw thread l0, and extends upwardly av considerable distance.

A reflector 13 'has a flat rim 14 resting upon the upper edge of the globe 12. The reiector 13 has a central opening l5 to convey a small quantity of light upwardly through the opening; otherwise the reiiec tor is impervious to light, and it may be of various materials such as glass or sheet metal; and preferably the reiector is annularly corrugated within the rim 111; and a coating 16 of opaque water-proof material is applied to the upper surface, and said Vcoatlng may be asphalt or the like, or it may be a coating of silver like. a mirror, with the back of asphalt or the like.

A cap 17 is preferably milk-white glass;

y lamp post; a head fixed in the Patented Feb. a, i919.

said cap has an inwardly projecting annular liange 18 restmg upon the rim 14; and

the cap 17 has an internally screw-threaded. rlm 19, screw-seated upon the upper end of' the globe 12.

The cap 17 is concave-convex and an ornament 20 may be mounted upon the apex of the cap 17.

In the practical application of my lamp, the light given Cif by the filament in the bulb 5 Vwill be reiiected upwardly by the reflector 11; and the light passing upwardly will strike the reflector 13, rebound and pass outwardly from the globe 12. A small quantity of light will pass upwardly through the opening 15 and be diffused through the milk-white shade or cap 17. The coating on the reflector 13 in intended to protect the reflecting surface against injury from sweating and moisture..

It will of course be understood that I may omit the opening 15 in the reflector 13. The cap 17 may be made of metal instead of glass, and various other changes may be made in the construction and arrangement of my lamp without losing the advantages described.

Various changes may be made without departing from the spirit of my invention as claimed.

I claim:

1. A lamp construction comprising, a upper end of the lamp post, said head being a iat circular plate having ventilator openings and having a seat in its upper face and a lamp socket at its axial center; a supporting iitting screwed upon the upper end of the lamp post; a reflector litting in the upper end of the supporting fitting and extending down- 9 wardly within the supporting fitting and restin in the seat of the head; and a tunnel shape translucent globe screwed into the upper end of the supporting fitting and forming a continuation or' the reflector.

2. A lamp construction comprising, a supporting fitting; a reflector mounted in the Supporting fitting; a funnel shaped translucent globe extending upwardly from the Supporting fitting; a reflector having a flat rim resting upon the upper ed e' of the translucent globe, said reflector icing circular, iiat and annularly corrugated; and a cap litting upon the rim and extending aroundthe upper end of the globe.

3. A lamp construction comprising a-supthe globe andl provided with a `Central aperportng ttlng, a reflector mounted therein, ture, and a translucent convex shade extenda source of light mounted Within the reing` upwardly from the upper edges of the 10 eotor, a funnel shaped translucent globe' translucent globe; Y 5 extending upwardly from the supporti-ng In testimony whereof I have signed my tting, a yreflector provided With annular name t this specification. corrugations secured to the upper edges; of. FREDERICK SHANNON MILLS.
