Y My invention. relates particularly to whatvare sometimes-called incandescent gas lighting de reliable type of portable lamp adapted to utilize a gas -tube lamp. These lamps are 4formed principally of glasswith an elongatedfchamber con-- taining aA suitable gasf'such as ne o n, andV some-- times containing mercury Vapor. f Such lamps require high voltage, at leastforjstarting, and it is customary to Vemploy a step-up 4transformer so that the lamp can be used ;on an ordinary house lighting-system which usually has a-voltage of t from 10,()Vto 220 volts,falthoughfthe;invention is not limitedfto any particular voltage or type of transformer-1 One Objectis to provide al cionstructionhaving' v a transformer and a housing for,y enclosing the transformer Yand z-suppo-rting the terminals, for vthe tube. Y f

Another object is to providerv aconstruction ofj this character with tube-receiving sockets or terminalswhich are completely housed and protected from accidental contact. t' I v Another object is to provide a means for electrically and mechanically protecting and supporting articles to be displayed. Y

In carrying out the invention I provide a main portion or base inthefform of a casing which encloses the transformer and has anl input cable and controlling switch.v On this base are mounted two terminalsockets connected to the output of the transformer but insulated from the housing and from each other. These sockets are enclosed in individual housings which also serve tosup-V port the ends of the gas tube. A supporting shelf or standard may also be employed to support articles to be displayed and illuminated by the light from the tube.

-Fig:.4 is a.; fragmentary plan viewand section. Fig. 5-isa vertical sectional view showing one of the tube terminals and its housing; The main housing forming the base consists of i aplate 'I and'a casing 8,'which parts have flanges which overlap andare detachably secured to- Y gether,- for instance; yby screws 9.v Thisbase'may be made of sheet'metal orof'insulating material Y iff desired. Y

The transformer maybe of any suitablecon-A struction having a core Ill adapted to be supported by bracketsII andsoftirubber pads I2 secured by boltsvI." The primary I4 .of the transformer isprovidedwith an input cord I^5j. The secondary I6 of theetransformer has outputleads IIconnected to terminal bolts VIdwhich also serve to hold thesocket-like clipsg- I9, These bolts vand terminal clips areinsulated from the top of` the casing 8.by an insulating'ndisc 2 0 andinsulating' The terminal sockets and the ends ofthe tube are enclosed in protecting housings each made up in the form shown of a screw base 24 and a cylindrical tubular portion 25 which is adapted to be screwed in to the socket 24. An insulating collar 2,5 is also preferablyprovided in the mouth of the tube 25 where it may be held in place by aV screw ring 21.

This collar-26 may be of soft rubber for affording a resilient lateral support for the tube. A

Each of the housings is also preferablyllined, at least partially, with a layer or tube 28 of insulating material. Y

A snap switchil isalso vpreferably provided in the basel and preferably in the low tension side of the circuit so that it will not have to handle the high voltageof the tube.

When such a device is used for advertising or displayv purposes it is desirable to provide some form of support such as a shelf 3l and/or standard 32. This shelf 3I may be supported on the upper end of the tubular housing 25. l t While I have shown the construction in its pre.-

that the claims are intended to cover modiica` tions and alterations. y

Such a lamp may be'made in many different forms and designs and the tube may be of variferred and simple form, it should be understood Y ous sizes and shapes. The lamp is portable and therefore avoids any of the installation difliculties commonly present with the usual so-called neon signs. In fact, the possibilities of use of this lamp are almost unlimited.

With this construction any design of tube may be used and various designs are interchangeable in the same base. 'Ihe tubular housings for the terminals not only prevent accidental engagement with the high tension output of the transformer but also serve to support and reinforce the tube at points above the base.

These lamps can be provided with tubes of various colors either by varying the color of glass or the type of gas used. Such tubesconsume but very little power, in fact, are most economical and are particularly adapted to use for advertising purposes. Y* Y I claim:

former housed in the base, said base having yielding supporting pads and brackets connecting the pads and the transformer, and tube-receiving sockets connected to the output of the transformer.

2. A portable gas tube lamp comprising a'hous ing, a transformer resiliently mounted therein and having input and output leads, tube-receiving terminals carried -by the housing, protecting means for said terminals, and means for support-V ing the walls of an inserted tube above `the terminals. l g

3. A portable gas tube lamp comprising a housing, a transformer mounted in the housing, yielding supporting pads for supporting the transformer, and tube-receiving terminals connected to the transformer.

4. In a gas tube lamp, agbase comprising a hollow housing including top; bottom and side walls, a transformer mounted'in the base and having input and voutput leads, spaced tube ref and projecting base and projecting upwardly therefrom, screw threaded oups on the top wall of the base and about the lower portions of the terminals, open ended tubular members disposed about said terminals and having their lower ends Vthreaded to said cups, and said members extending above said terminals and comprising tube supports.
