Among the objects of my invention are further the-provision in a housing for new tubes of, an improved contact arrangement for introducing electric currentdntoH-the tube, and the provision oftan improved arrangement whereby a neon tube will be securely held in;the housing. To attain these objects and-such further objects ;as may appear herein orgbe hereinafter pointed out, I make reference to the accompany ing drawings, forming aparthereof; in which:

A second alternative-form for use-with the installation of Figure 1 is-shown in Figures 9,- 10

" In thisform, the hollow body portion 28|l,'similar to the body 260;isprovi'ded with dished tubereceiving seats '28! along its rim. Brackets-282; projecting outwardly from'thebocly 280; are posi tioned one below each seat 28! ,and each bracket has two spaced holes 283 -therein.- Aneon tube 284-is adapted to seat on 'aseat 28! and may be held thereon by a resilient'clip 285','-having' two legs 286 and 281, adapted for insertion into the holes 283, and provided-in theillustrated form with a looped bight portion. i

In order to increase the holding powerofthe clips and lessen the chances of their accidental disengagement, the ends 289 and 290 of the legs 286 and 287 may be bent laterally outward so as to producea shoulder effect that will increase the resistance to withdrawal of the legs from the holes.

In Figure 11 I have illustrated the adaptability of this construction for use with neon tubes of different diameters which areindicated by the dot and dash circles 284' and 284". Obviously, the clip 285 is adaptable, with suitable manipulation, to clamp either of them in place.

The body 288 is also provided with suitable at taching lugs 29 l It will be observed that common to the various embodiments described and illustrated in Figures 1, to 11, there is provided in an insulating housing for the purposes described, a seat for locating the neon tube, avoiding the need for the employment of the usual elevation posts for such illuminants, to bind and to mount the same to some frame, so that the housing not'only displaces these usual contrivances, but more effectively gains compactness and eliminates light obscurations and minimizes interference with the re-;

flective surface in association With which the neon tubes are mounted. It will thus be observed that I have provided a housing adapted for use with neon tubes having electrodes such as described in my aforementioned Patents Nos. 2,2'Z1,657 and 2,271,658, and that is simple, effective and economical.

While these improved housings are particularly the manner of their use, it is to beunderstood that my invention may be embodied in many other forms, as will be obvious to those skilled in the art, without departing from the spirit thereof, and that the disclosure herein is by way of illustration merely and is not to be interpreted in a limiting sense, and that I do not limit myself other than as called for by the, language of the appended claims.

Having thus described my invention and illustrated its use, What I claim as new and desire to secure by Letters Patent is:
