Under some circumstances it may be desir able in some cases to provide an external globe 26. A water tight connection is also desirable between the globe 26 and the c aeing 5. 'lhis may be provided by a yielding gasket 27. To hold the globe in place l may provide a ring 28 which may be clamped to the casing 5 by screws. 29. A yielding gasket 30 may be interposed between the ring 28 and a shoulder of the globe near its base. Suitable Ouard wires 31 may be provided and secured to the ring 28 in any suitable manner so as to mechanically protect the glass and also so as to prevent tampering with the lamp and its connections. A switch 3a of the conventional type is indicatedas connected in the low tension leads to the transformer and as operable from the exterior of the casing 5.

lt will be understood that the transformer and socket combination may be made and sold as a unit for installation in various ways 1t will also be understood that the construction of the lamp per se is not material to my present invention. 1n fact in place of the helical tube shown in Fig. 1 l may employ a tubehaving a spiral conformation as shown in llig. 2 at 32 which latter affords a broad surface especially when viewed from the front light concentration. Such gas tubes may also have the form of individual letters or words.

rfhese lamp sockets are preferably installed in protective housings as above described and anyV number may be used collectively. 'llhese lamps may be provided individually with switches preferably on the low tension side, as indicated at 34: or other suitable operating means may be employed so that the lamps may be individually controlled immediately adjacent the light source or the control may be from a distant point or points of the low tension circuits thereof. y

The cup member 7 serves as a container for the transformer and by. virtue of its shape it allows the employment of insulating media to form a suitable circuma'mbient milieu for the transformer. The employment of such insulating 'media to completely surround a transformer, for purposes of protection against moisture, greater insulation, better cooling or similar purposes, is well known in the electrical art and does not constitute an essential part of my invention.

It will be seen from the foregoing that l have endeavored to arrange a system and construction by which these gas lamps may be* made, sold and installed v ery much the same y as incandescent filament lamps are handled. A

The commercial and utilitaman advantages of such a construction and installation will be apparent.

I claim: l

1. A gas lamp socket having two insulatresaeae ing parts directly fastened to one another and substantially enclosing a chamber between them, a step-up transformer supported -by one part in said chamber and having output leads Secured to the other part, the latter part having contact terminals for tube prongs.

2. A gas lamp socket having an insulating part with a recess in its upper face and an extension chamber, contacts mounted in said' chamber, an insulating shield secured insaid recess and having passages for tube prongs and a step-up transformer having its output leads connected to said contacts.

8. A gas tube socket having insulating parts a step-up transformer mounted in one part, the other insulating part having chambers containing prong contacts connected to the high tension leads of said transformer and an insulating shield having passages for prongs leading to the contacts.

Il. A. gas tube socket comprising a metallic housing, an insulating cup supported in said housing, a step-up transformer supported in said cup.,- a switch in the low tension side of the transformer, and an insulating part sup ported on the cup and having contacts for a tube connected to the output of the transformer.,

5. i gas tube socket having insulating parts a step-up transformer mounted in one part, a snap switch associated with the low tension side of the transformer, the other insulating part having chambers containing prong contacts connected to the high tension leads of said transformer and an insulating shield having passages for prongs leading to the contacts.

6. Gas lamp apparatus comprising a casing consisting of a cup member and an insulating socket forming a closure for the casing, a transformer enclosed in said casing, and prong contacts in the insulating socket connected directly to the high tension output of the transformer said socket having individual passages for prongs leading to said contacts.

A gas lamp structure comprising a transformer casing, an insulating socket mounted thereon and forming a closure therefor, said socket having spaced recesses in its i I'GCESSGS.
