Q/Jarz YWd/iJQ/J ATTORNEYJ} Patented Mar. 3, 1936 NlTED STATES PATENT GFFIQE ELECTRIC LAlVIP MOUNTING ApplicationJuly 14, 1933, Serial No. 680,385-
4 Claims.
This invention relates to lighting fixtures, and more particularly sockets for incandescent lamps; and it is among the objects of the invention to provide a mounting for plural lamps for composite eifect. Another object is the provision of a construction capable of aligning the luminous centers of lamps in definite relation to each other. Other objects and advantages will appear as the description proceeds.
To the accomplishment of the foregoing and related ends, the invention, then, comprises the features hereinafter fully described, and particularly pointed out in the claims, the following description and the annexed drawing setting forth in detail an illustrative embodiment of the invention, this being indicative however, of but one of the various ways in which the principle of the invention may be employed.
In said annexed drawing:
Fig. 1 is a diagrammatic showing illustrative of the principle of the invention; Fig. 2 is an inverse plan view of an assembly as in position on a ceiling; Fig. 3 is an end view of a mounting in accordance with the invention; Figs. 4 and 5 are plan and side elevational views of the same, respectively; Fig. 6 is a section taken on a plane substantially indicated by line VI--VI, Fig. 4; and Fig. 7 is a section taken on a plane indicated by the line VII-VII, Fig. 4.
In its general aspects, the invention contemplates a mounting for incandescent electric lamps, providing placement of the luminous portions of the lamps in alignment to a common center line, with a very moderate space-requirement, and preferably with the axes of the lamps directed at a slight angle from the horizontal, to allow clearance for the radii of the bulbs.
As shown in Fig. 2, a desirable embodiment involves lamp-receiving shells 3, 4, 5, 6, paired laterally, thereby shortening the distance between luminous portions of the lamps to less than twice the length of the lamp. By angular inclination also toward the common center line, the luminous portions I, 8, 9, I0, of the lamps are aligned-to a common center-line, the luminous portions having an equalizing distributive effect. Such lamp-receiving shells may be mounted individually upon a suitable general base II of a character to be secured to a ceiling or wall surface, and receive a suitable glass cover, as need not be further detailed.
Instead of separately mounted lamp-receiving shells positioned to maintain a relationship as above described, I may advantageously support the shells on an insulating block in common, as
for instance insulating block I2, Figs. 3-7. This may be formed of any suitable insulating material, porcelain, composition, etc., and through suitable recesses 13, I4, allows access of wiring for connections to the terminals I5, I6. Shellreceiving recesses II are formed in the block, oppositely directed, and enlarged outwardly as at I8, to afford clearance for a lamp-bulb in position. The axis of each such lamp-receiving shell is at a slight angle to the horizontal, as indicated in Fig. 6 more particularly, and the respective shells are also directed at an angle such as to converge toward a common center line, the luminous portions of each lamp coming to a position thereon. Leading from the respective wiringterminals I5, I6, are bus-bars I9, 20, one passing across above, and the other below, and each connecting to corresponding points on the shells, for instance in the particular form illustrated, thev bus-bar I9 is secured to the respective shells 2|, 22, by rivets 23, and the bus-bar 20 connects by branches 24, 25 to the center contacts 26 in the shells. Advantageously, the bus-bar means may also constitute a means in common for securing the shells to the block I2, rivets or other suitable fastenings 21 being provided through the bus-bar I9 into the mounting block. The bus-bar 20 may be suitably anchored to the block by a screw 28, and rivets or other suitable fastenings 29 serve to anchor the bus-bar and branches 24 securely. The insulating block I2 may be secured to its support, as to the base-plate II, by suitable screws or bolts through openings 30, Figs. 4, 5, and 6.
With the base I I and a pair of insulating blocks I2 for instance of porcelain, with their so-supported shells 2 I, 22, and the latter supplied with suitable incandescent lamp-bulbs, for instance watt bulbs, the alignment of the whole set of luminous portions is concentrated to a common line, and the spacing is such as to provide a particularly efficient light-distribution, especially with semi-translucent or other suitable coverglass over the whole.
Other modes of applying the principle of the invention may be employed, change being made as regards the details described, provided the features stated in any of the following claims, or the equivalent of such, be employed.
I therefore particularly point out and distinctly claim as my invention:-
1. A lamp-mounting, comprising an insulating block, wiring recesses adjacent each end of said block, oppositely-directed transverse recesses in said block, metallic lamp-receiving shells in said recesses directed slightly upwardly and inwardly, a bus-bar connecting from one wiring recess to extend over said shells and being fastened thereto and to the block, and a bus-bar connecting from the other wiring recess and extending under said shells and fastened thereto.
2. Means for holding a pair of lamp bulbs with their bases overlapping and their luminous porshells in said recesses directed slightly inwardly, a metallic connecter bar extending over both said shells and holding them and supplying current thereto, and a metallic connecter bar extending under said shells insulatively thereto for supplying current at the ends of said shells.
4. Means for holding a pair of lamp bulbs with their bases overlapping and their luminous portions oppositely directed for alignment, comprising an insulating block, oppositely-directed transverse recesses therein, metallic lamp-receiving shells in said recesses directed slightly inwardly, Wiring recesses positioned externally of said transverse recesses, a metallic connecter bar extending from one wiring recess over both said shells and being fastened thereto and to the block, and a metallic connecter extending under said shells from the other Wiring recess and supplying current at the end of said shells.
