PATENT ossion HEAD! AND SOCKET FOR INOANDESCEN'I LAMPS.,

Specification of Letters Patent.

Patented 0a. e, 1908.

Application filed June 21, 190's. Serial No. 822,768.

To all whom it may concern:

Be it known that I, BENJAMIN 'Pamcs RUOI'EB, a-citizen of the United States, and a' resident of Wilkinsbur in the county of Allegheniy and State of l enns lvania, have invente a new and useful mprovemept in Shades and Sockets for Incandescent Lamps, of which the following is a specification.

My invention relates to shades or reflectors that are employed in connection with incandescent lam s, and it has for its object to provide a re ector of. such a structure that it may be secured directly to a lamp socket and may serve to cover t e same and 'revent oxidization and destruction thereo The sockets for incandescent electric lam nratlsually mounted within, but insulate from, metallic. ca s or shells to which suitable brackets'a're o ten secured for supporting shades or reflectors, but when such structures are emplo ed in out-of-door lighting systems and in actories or other places where moisture, gases and fumesjare 'revalent,'they are frequently oxidized an graduall? destroyed, and the supportin brackets or the reflectors are soon renders useless by breaking or by separation from the shells to which they are secured. 4

- Accordin' to' the present invention the shade or re ector is extended to form a cap that completely surrounds and protects .the socket, except the end into which the lamp is adapted to' e inserted, and the two parts may be, and preferably are, suitably fastened together by suitable waterproof cement which also serves toprevent lea 5 around the terminal conductors that project through a comparatively small opening in the end of ample, by means of the cap.

The nature of the invention may be better understood from a consideration of the accompanyin drawing, Figure 1 of which is a view partia ly in side elevation and partially in section of a structure that embodies the same, and Fig. 2 is asimilar view of a modification of the structure of Fig. 1.

A shade or reflector 1, that may be of any of the well known or other types, is-provided with a substantially cup-shaped extension or cap 2 inwhich a's'ocket 3 for a lamp 4 is secured inany suitable manner, as, for ex- .water-proof cement 5. Circuit connections to the socket are made by means of conductors 6 and 7 that in the resent instance project through an aperture in the end of the cap and are secured respectively' to the terminal portions :oflthe socket, and that ma serve as means'for suspending the lamp an the reflector directly. from the socket and the cap and closely surrounds the ends of the conductors (i and 7, thereby preventing'water, air ands ases from causing oxidation or corrosion o the external surface of the socket. The reflector is composed of glass or porcelain, or another non-corrosive insulating material.

When it is desired toattach the reflector to a chandelier or to a pipe in which the supply conductors are located the reduced and .of an internally screw threaded sleeve 8, (Fig. 2,) ma be inserted in the a erture in the, end of t e ca 2 as far as'a s oulder 9 reflector may be secured thereto by'any suitable means as by flaring of the inner end theres of as at 10.

The structural details and arrangements of the-parts are capable of further modificaparting from the spirit of the invention, and desire that all such modifications be included within its scope.

I claim as new, and desireto secure by Letters Patent, is- 1. he combination with a non-corrosive insulating shade or reflector havin an integral protuberant ca or dome, o a lam socket located entire y within and sheaths by the ca or dome, the latter conforming substantia ly in sha e to the socket and extendin over one en thereof.

2. Tie combination with a non-corrosive insulating shade or reflector havi an integral protuberant ea or dome, o a lam socket located entire y within and sheathe by the ca or dome, the latter conforming substanti ly in shape to the socket and extending over one end thereof, and. conducting leads that connect to the socket and project through the ca or dome. 3. The combination with a non-corrosive insulating shade or reflector having an integral protuberant ea or dome, of a lamp socket located entire y by the-ca or dome, the latter conforming substantia ly in sha e to the socket and extending over one en thereof, and cement securing the socket in ing the interstices between the said parts.

supply conductors; or from ceiling rosettes. The cement 5 fills the. space between the that is provided y the reduction, and the Having thus described my invention, what a tion within considerable limits without dewithin and sheathed the cap or dome and fill I 5. The combination witha lamp socket, of

a shade or reflector having a protuberant c'ap or dome that serves as a sheath or covering for the socket and i's provided with an aperture, a sleeve thatprojects through the aperture and to which the reflector is secured, and

COIfJUGtOI'S that connect to the socket and extendoutyvardly through the sleeve.

6. The combination with a lamp socket, of a non-corrosive insulating shade or reflector havin an integral protuberant cap or dome that c osely surrounds and sheathes substantially all but the open end of the socket.

In testimony whereof, I have hereunto subscribed my name this 19th day of June,-

BENJAMIN PARKS BUCKER.
