To all whom it may concern:

Be it known that we, GEORGE L. PATTER- SON and JAMES B. FARRELL, citizens of the United States, residing at New York, N. 1., have invented certain new and useful Improvements in Electric-Lamp Receptacles, of which the following is a full, clear, and exact description.

Our invention relates to improvements in electric lamp receptacles, the object of the invention being to provide a superior construction, the various parts of which may be more readily assembled than in the past, the construction of which is such that shortcircuiting is prevented under all conditions, especially in outdoor work, where rain is liable, in the ordin ry construction, to cause said short-circuiting. In structures of this type corrosion of the metal parts is a thing that cannot be avoided, and, in many instances, such corrosions produce shortcircuiting across the terminals. By our construction this is entirely avoided. Drainage is also provided to prevent the accumulation of water at points where such accumulation would produce the aforesaid shortcircuiting.

In the accompanying drawings-Figure l is a side elevation of the receptacle assembled and with a lamp in place, Fig. 2 is a lan view of the lower section of the receptacle, Fig. 3 is a side elevation thereof with the metal parts removed, Figs. 1, 5 and 6 are detail views. Fig. 7 is a plan view of the porcelain base alone.

1 is a base of suitable contour and ordinarily made of porcelain, or other suitable insulating materia. 2 is a socket, screwthreaded to receive a lamp 3, of the usual incandescent type.

44 are outwardly projecting flanges on socket 2. 5 is a clearance recess through the lower side of said socket.

6 is a terminal having bifurcated ends -6 arranged to extend partially around the outside of the base of the socket 2, and bear upon the flanges 4-4 thereof, whereby by the use of suitable screws 77, both the terminals 6 and socket 2 are held in place and at the same time an electrical connection between said parts is provided. 8 is another terminal, terminating directly under the center of the socket 2 in the usual manner, and against which a central terminal of the lamp proper engages.

999 are the walls of the dam around the terminals 8.

1010 are the dams around the bifurcated ends of the terminal 6. Between these dams 9 and 16 are drainage canals 1111, increasing in depth as they extend away from the center.

The usual wire connections are made in the usual manner, customary with such devices, and no explanation is necessary.

12 is a cap-piece which overstands the base 1 when the receptacle is assembled, ready to receive the lamp.

In outdoor use water is liable to be driven into the space between the lamp and the surrounding wall of the cover 12. In the ordinary construction this water accumulates within the receptacle and causes shortcircuiting and encourages corrosion. By our improved construction, no water is permitted to accumulate, since by the use of the drainage canals 1 11 1, the water is instantly rawn off. The terminals 6 and 8 are separated to such an extent that short-circuiting is practically impossible.

It should be understood that the drainage canals 11-11 pass under the arms 6*6 of a sufficient depth to prevent any danger of short-circuiting by the presence of any water moving outwardly through said canals. The dams 1O serve not only to prevent the driving in of water, but also serve to center the cap 12. This dam 10 also prevents the leakage of current from the part 6 across to the usual holding screw (not shown) located nearby on opposite sides when the receptacle is mounted ready for use.

What we claim as new is 1. In an electric lamp receptacle, a porcelain base, a metallic socket, a terminal electrically connected with said socket, another terminal extending to a point central with respect to said socket, and drainage canals in the porcelain base extending laterally from points below the socket to the outside of the receptacle body.

2. In an electric lamp receptacle, a base of insulating material, terminals carried thereby and including a lamp socket, drainage canals in the insulating base leading laterally from points adjacent to the foot of the socket to the edge of the base.

3. In an electric lamp receptacle, a base of insulating material, a socket, a terminal having a bifurcated end partially embracing said socket and external thereof, another terminalprojecting into the-space below said socket.

4. In an electric lamp receptacle, a base of insulating material, a metallic lamp socket carried thereby, external flanges at opposite sides thereof, a terminal partially embracinn said socket, and an electrical connection therewith through the medium of said flanges.

'5. In an electric lamp receptacle, a base,

of insulating material, a metallic lamp socket 7 carried thereby, terminals carried thereby, dams formed integrally therewith and protect-ing said terminals and drainage canal's' from the center of said receptacle to the outer edges thereof.

6. In an electric lamp receptacle, a base of insulating material, a socket flanged outwardly at its lower end and arranged to be supported by said insulating base, a terminal having a curved end conforming substantially to the outer Wall of the socket and arranged to rest upon and reinforce the flanged lower end of said socket, means for securing said parts together, and another terminal carried by said insulating base ing into the space within said socket.
