Lighting fixture

Application filed June 6,

My invention relates to a new and useful lighting fixture, particularly adapted for use as illuminated signs. .

My invention relates more particularly to 5 a new and useful illuminated sign construction, including an annular metallic housing or rim in which a pair, of transparent, or translucent or partially opaque, glass discs : are mounted, carrying the suitable signs 10 thereon, and between which a source of light is disposed.

My invention further relates to a novel construction in an illuminated sign of the ^: above type, whereby a more durable and less 13 fragile device, is produced and whereby the maintenance of such sign will be greatly facilitated.

For the purpose of illustrating my inyention I have shown in the accompanying so drawings one form thereof which is. at present prefer red by me, since the same has been found in practice, to give satisfactory and. reliable results, although it is to be. understood that the various instrumentalities of 3 which my invention consists can be variously arranged and organized and-that my invention is not limited.to the precise arrangement and organization: of the instrumentalities as herein shown and described.

In the accompanying, drawings in which like reference characters indicate like parts:

Figure 1 represents a vertical longitudinal section of my novel illuminated sign, taken generally on 'line 1—1 of Figure 2, and showⁿ·⁵ ing a general side elevation of the device. ·

Figure 2 represents a vertical view, of an encl or edge of my novel illuminated sign.

Figure 3. represents a side elevation, on a reduced scale. . .

^φ'^! My novel construction in an illuminated sign, includes a generally annular and cylindrical shaped body 4, of any suitable gauge sheet metal, (preferably bronze or the like) to the upper part of which the supporting ⁴⁵ voke 5 is secured, in a manner shown particularly in Figures 1 and 2.. The yoke 5 may . be formed of a band or strip of metal having the. two legs 6 . and 7, which , are secured to the annular body 4 at the points 8 and 9, ⁶⁰ and which includes an upper central horizon2 1,851,335 to the housing. The spring leaf 29 is secured to the rim 23.

A series of ventilating holes 30 are provided through the top of the housing, be5 neath the yoke 5. A corresponding series of vent holes 31 are provided in the bottom of the housing.

The advantage of my novel construction is that a more durable and serviceable illuminated sign may be provided, which will withstand any unusual strain and which may be serviced more readily by merely removing one of the glass faces of the sign. Thus the cost of maintenance is also greatly reduced 15 over the conventional all-glass illuminated signs, since the cost of replacing a broken glass plate is considerably less than the cost of an all-glass fixture.

Due to the provision of the series of super20 imposed vent holes at the top and bottom of the housing, a constant cooling air draft is maintained through the interior of the sign, thereby preventing overheating of the glass plates and the resultant deterioration 25 of the coloring thereon. The top vent holes are shielded from rain or the like by the upper yoke member 5, so that a dry air draft may be maintained through the sign and so that the formation of corrosive and deteriorating 30 steam vapors within the sign is entirely eliminated.

I am aware that the invention may be embodied in other specific forms without departing from the spirit or essential attributes 35 thereof, and I therefore desire the present embodiments to be considered in all respects as illustrative and not restrictive, reference being had to the appended claims rather than to the foregoing description to indicate 40 the scope of the invention.
