LAMP-HOUSING.

Specification of Letters Patent.

Patented Nov. 18, 1919.

Application filed November 4, 1918 Serial No. 261,087.

To all whom it may concern:

Be it known that I, PAUL D. Howsn, 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-Housings, of which the following is a specification.

My invention relates to a lamp housing and more particularly to a street lamp housing adapted to be mounted on a lamp post.

One object of my invention is to provide a street lamp housing which readily may be mounted upon a lamp post or removed therefrom.

Another object is to provide a street lamp housing which is made in parts so that broken parts easily may be removed and replaced by new ones.

Another object is to provide a street lamp housing having a top reflector adapted to reflect the upwardly directed light rays diagonally downward through the housing plates, thus increasing the efiiciency of the lamp.

With these and other objects in view my invention consists in the construction, combination and arrangement of parts hereinafter described and claimed.

In the accompanying drawings which form a part of this specification,

Figure 1 is a-view in perspective of a lamp post equipped with a lamp housing embodying the p-rinciplesof my invention.

Fig. 2 is an enlarged view in elevation of the lamp housing shown in Fig. 1 parts of whichare broken away to more clearly disclose its construction.

Fig. '3 is an enlarged .fragmentary sectional View taken on the -lineq33 of Fig. 2.

Fig. 4 is a View in perspective of one of the .re 'novable frame pieces composing the lamp housing.

Flg. 5'is aview in perspective of one ofthe glass plate sections included in the lamp housing.

The lamp housing shown in Fig. 2 com prises ,a metal base plate 10 preferably made in the form of a regular octagon with a circular portion out out of its center and the inner edge of the disk turned downwardly and outwardly to form a curved base flange 11 adapted to be mounted in the upper end of a lamp post.

Concentric base bands 12 and 18 having their lower edges soldered to the upper face of the base plate near its margin form an octagonal groove 14: around the base plate. The base bands are slightly expanded upwardly so that the groove walls are inclined outwardly as well as upwardly from the base plate. Equally spaced frame bars 15 having their lower ends fixed to the inner base band 13 extend upwardly from the base plate, diverging slightly from below up ward, and have their upper ends turned outwardly at approximately right angles to the bar to form fastening lugs 16 for attach ing the shaderoof. The upper ends of these frame bars are held in equally spaced re lation to each other by a top band 17 to which they are soldered. The roof 18 is pyramidal in form to correspond with the octagonal form of the lamp housing and has its outer edge bent downward and returned under lugs 16 of the frame bars, thus forming a clamping flange 19 which rigidly supports the roof on the frame bars. The parts thus far described constitute the fixed framework of the lamp.

The removable frame pieces 20 consistof a long arm 21 bent longitudinally at its middle to conform to the external angles of the octagon and a short arm 22 joined to one side of its upper end approximately at right angles to it. The short arm has its upper edge bent sidewise to form a flange 23 adapted to fit under the clamping flange 1,9 of the roof plate. Holes 24: are bored through the middle of the long arm in equally spaced relation to similar holes 25 bored in frame bars 15, so that when the removable frame piece-is in place these holes will coincide to receive clamping screws 26 which hold the fixed and movable frame parts together. Nuts 27 are soldered to the inner faces of the frame-bars 15 to engage the clamping screws. '1he frame parts of the lamp housing, on the whole, are made of comparatively thin sheet metal Translucent bars and plates 28, preferably made of glass, are cut with parallel ends and straight lnclined sides adapted to fit in the spaces between the frame bars. These plates are mounted in the lamp with their narrower ends resting in the base groove 14 and their wider ends supported in the angles 29 formed in the short arms 22 of the removable frame pieces. Their sides contact with clamping screws 26, the spaces between them being covered by the frame removable frame bars 21 between which their adjacent edges are clamped by the clamping screws.

' The lamp thus constructed is mounted on a lamp post 30 having an annular flange 31 formed aroundits top through which retaining screws 32 are tapped, so that their ends extend through the flange and engage the curved flange 11 of the base plate, thus securely holding the lamp on the lamp post.

The lamp housing thus described is' my preferred form. In it the inner surface 33 of the roof piece 18 is polished to serve as a reflector and it reflects the upwardly radiated rays of light diagonally downward across the interiorxof the lamp housing and through the side lates which are opposite the reflecting surfaces. A more direct reflector may be supplied in the forni of a special reflector plate 3a having an inverted pyramidal form adapted to have its marginal edge 35 clamped between the roof plate 18 and the supporting lugs 16 of the fixed frame bars 15. The reflecting surfaces thus provided will reflect the upwardly directed light rays diagonally downward through the plates on the adjacent side of the lamp housing. I

Operation: The operation of mounting or removing the lamp from the post is evident. The retaining screws 32 are turned backward until their inner ends are flush with the inner periphery of the flange, whereupon the lamp can be lifted oflf its post.

When it is desired to remove a plate which has been broken, or to insert a new plate, the removable framepiece 20 of the broken section. is loosened by withdrawing the clamping screws 26, whereupon the removable frame piece is detached from the side of the lamp. The broken glass may then be'removed and a new plate inserted. The removable frame piece is then replaced and the screws tightened until the plate is securely clamped against the inner frame bar. It is evident that these operations may be performed without removing the lamp housing from the post or disturbing any of its unbroken sections.

Another advantage of my improved lamp housing is that in case of breakage of one of the translucent side plates the electric light bulb within the housing l it housings of ordinary construction.

. While I have shown an eight sided lamp housing it is evident that it may be made with a larger or smaller number of sides,

3 and it will be understood that various other changes in construction and arrangement of parts may be made by those skilled in the art without departing from the spirit of my invention as claimed.

I claim:

1. A lamp housing comprising, a metal framework including a base plate adapted to be mounted on a lamp post, concentric bands aflixed to said base plate so as to form a. groove, upright bars having their lower ends fixed to the inner band of said concentric bands, a top band fixed to the upper end of said upright bars, a roof and reflector plate fixed to said upright bars, removable frame pieces adapted to cooperate with said upright bars, translucent plates held between said upright bars and said removable 4 frame pieces, and clamping bolts adapted to hold said removable frame pieces in clamping relation to said upright bars thus clamping the sides of said translucent plates and covering the space between their adjacent edges.

2 A lamp housing comprising a metal frame-work including a base plate adapted to be mounted on a lamp post, concentric bands aflixed to the base plate so as to form a groove, upright bars having their lower ends fixed to the inner one of the concentric hands, a top band fixed to the upper end of the upright bars, removable frame pieces adapted to cooperate with the upright bars, plates held between the upright bars and the removable frame pieces, clamping bolts removably inserted through the removable frame pieces and through the upright bars, and nuts soldered to the inner faces of the upright bars to receive the bolts so that the bolts may be removed from the outside to remove the plates without removing the housing from the support. I

- 3. A lamp housing comprising a metal framework including a base plate having an outwardly curved downwardly extending flange forming an external groove and adapted to fit in a flange upon a lamp post and be held in place by screws tapped through the lamppost flange and engaging inthe groove, concentric bands aflixed to the base plate so as to form a groove, upright bars having their lower ends fixed to the inner one of the concentric bands, a top hand fixed to the upper end of the upright bars, removable frame pieces adapted to cooperate With the upright bars, plates held between the upright bars and the removable frame pieces, clamping bolts removably inserted through the removable frame pieces and through the upright bars, and nuts soldered to the inner faces of the upright bars to receive the bolts so that the bolts may be 10 removed from the outside to remove the plates Without removing the housing from the support.

In testimony whereof I have signed my name to this specification.
