12 Claims.

Objects of the present invention are: to provide fixtures or lights of the type recited which effect a uniform distribution of light wthoutobjectionable glare, to dispense with glassware which is apt to be broken and to avoid the use of globes which are expensive and are alsov subject to breakage, to provide for adapting the same unit to a standard, bracket or hanging type mounting, and to provide an emcient, attractive and durable street lighting fixture.

To these and other ends hereinafter set forth or appearing the invention, generally stated, comprises, a street lighting iixture of the indirect type comprising in combination a base having a lamp mounted on it, a metallic bowl detachably mounted on the base and having an opening through which the lamp projects and having air vents in its walls, a bezel or like ring provided with a glass and mounted on the bowl and having feet providing air vents, arms carried by the bowl and to which the bezel ring is detachably connected, and a canopy carried by the arms and provided with a conical reector projecting toward the lamp.

The invention also consists in the improvements to be presently described and finally claimed.

In the following description reference will be made to the accompanying drawings forming part hereof and in which,

Figure 1 is an elevational View of a street lighting fixture embodying features of the invention and mounted on top of a post.

Figure 2 is an elevational view, drawn to an .enlarged scale, of a xture embodying features of the invention and adapted for application to a post or bracket or hanging type of support.

Figure 3 is a sectional view illustrating features of construction.

Figure 4 is an elevational View partly in section illustrating the street lighting fixture in application to a bracket support.

Figure 5 is a sectional View taken on theline 5--5 of Figure 4 and drawn to an enlarged scale with parts omitted, and

Figure 6 is an elevational view of the fixture in application to a hanger.

Referring to the drawings, I is a bowl of metal or like material and it has anopening 2 through 504 which alamp 3 projects. The bowl is also provided withair vents 4 through its wall and near its base. 5 is a bezel or like ring, and it is provided with av glass 6, generally flat as shown in Fig. 4 and in the form of a lens as shown at 6a, 55 Fig. 3. Thering 5 is tted with feet 1 which stand upon the bowl I and provideair vents 8. The feet 'I of thering 5 are spaced apart and they are arranged in two concentric circular rows and the feet in one row are opposite the spaces between the feet in the other row, providing a baiile effect. 9 are arms carried by the bowl I and to which thering 5 is detachably connected, for example, by means of set screws I0. II is a canopy carried by the arms and it is provided with a conical reector I2 projecting toward thel0 lamp 3.

As shown in Figures 1 and 3 the bowl I is mounted upon the base I6 at the top of a lamp post I3 and the base I6 projects into the bowl and supports it at its rim by a ilange Il. The l5 base I6 is provided with ribs M which with theholes 4 arranged between the ribs provide air passages and the ribs Ifl serve to receive the screws I5 by which the bowl is secured to the base. 26 is a lamp socket and it is mounted on a 0plate 21 adjustable uponstandards 23 rising from the base I6 by means ofclips 29, in order to properly place the filament of the lamp with respect to the lens cover 6a. or glass 6, and the reflector 2l, for getting the desired direction of light from the lamp on the reector I2 and from the latter outwardly and downwardly, as required. It is an advantage of the described fixtures that they can be used interchangeably with the baseat the top of a lamp post or with a similar base forming part of or connected with a bracket or hanging type mounting provided with a lamp.

As shown in Figure 4 the bowl I is mounted in a clamping ring I8 provided by the bracket I9 3- shown as mounted on a standard ZIJ. Ia is a base depending from the bowl I. 2l is a metal reflector depending from the top rim of the bowl I and stopping short of the base to provide air circulation around the lamp. The reflector 2I is useful with an ordinary lamp but where a silvered lamp, as at 3a, shown in Figure 3, is employed the reector 2l is not necessary in all cases.

As shown in Figure 6 the bowl I is suspended from asupport 22 and for this purpose use may be made ofarms 23, shown in Figure 6 in dotted lines, and these arms are connected with aneyebolt 24. 25 indicates provisions by which the conductors may be led into the structure for supplying the lamp with current.

In use the exposed parts are of metal and are therefore not likely to be broken by the abuse to which street lights are subjected, such as stones thrown by irresponsible people and boys. The

glass and lamp are so located that they are well protected from such objects .and in fact from any objects coming from the ground. The described relation of the parts gives rise to a uniform distribution of light while at the same time objectionable glare is avoided.

It will be obvious to those skilled in the art to which the invention relates that modifications may be made in details of construction and arrangement and in matters of mere form without departing from the spirit of the invention which is not limited in respect to such matters or otherwise than as the prior art and the appended claims may require.
