Application filed November 2, 1926. Serial No. 145,880

This invention relates to illuminated' signs and has particular reference to an interchangeable or convertible sign element which is particularly applicable to signs of the type set forth in my co-pending application, Serial N 0. 140,901, -filed October 11, 1926. One of the outstanding objects of the present invention is to provide a sign element which simulates an electric bulb and which may be illuminated either by reflection from a flood light or by penetration of light rays therethrough from a source of light.

More specifically the invention comprehends a convertible or interchangeable sign element includinga bulb andinterengageable means within the open inner end thereof and on a plurality of respectively transparent and reflective plugs whereby interchanging of the type of plugs desiredis facilitated to render the bulbs convertible for flood lighting or penetration illumination.

The invention furthermore comprehends the use of bulbs and plugs of different colors which may be combinedin various ways to obtain a multiplicity of effects.

The invention aims as a further obj ec'tto provide interchangeable convertible sign elements which are comparativelysimple, inexpensive and eflicient. V

With the above and other recited objects in view, reference is had to the following specification and accompanying drawings in which there is exhibited one example or embodiment of the invention which is in no way intended as a limitation upon the scope of the appended claims as it is to, be clearly" understood that variations and modifications which properly fall within the scope of said claims may be resorted to when found expe dient.

In the drawings Figure 1 is a sectional view illustrating one of the sign elements in applied position and having a reflector plug associated therewith to permit of the use of the element in connection with a flood light. I

Figure 2 is a sectional view taken mately on the line 22 of Figure 1;

Figure 3 is a rear view of the plug element removed;

Figure 4 is a sectional view similar to Fig ure 1 with a transparent plug associated with the bulb to permit of illumination by penetration;

approxistituting the present bulb 12 of glass or other transparent material. substantially simulating an electric lamp or Figure 5 is a rear view of lustrated in Figure 4%. I

Referring to the drawings by characters of reference, 10 designates the sign base which may be the wall of a cabinet, a pa'nel'or the like, and which base is provided with an aperture or apertures 11.

invention includes a bulb,and provided at its open restricted end with interior and exterior threads 13 and 14. The exterior threads 14 are adapted to engage within the threaded socket member 15 which is attached to the base 10 and is disposed in alignment with the aperture 11 whereby the bulb 12 is detachably connected with the base. 7 The, sign element further includes a plug 16 which is exteriorly detachably fit within the interior threaded end 13 of the bulb and said plug may either be opaque and have a reflecting lens 18 on its outer face, or may be of a transparent nature as designated by the reference character 19 in V Figure 4. The reflector or transparent plugs may be of different colors as may be the bulbs 12 whereby difi'erent may be obtained. Where the sign is to be illuminated by a flood light the reflector plugs are associated with the bulbs 12, and conversely where an interior penetratingsource of light is to be used for illuminating the sign the device as ilor varied color effects The sign element conthreaded at 17 to,

transparent plugs 19 are associated With the bulbs. In order to facilitate the association and disassociation of the plugs with the bulbs the'plugs are preferably formed on the rear face with a rib 20 to constitute a finger grip for screwing and unscrewing the plugs;

From the foregoing it Wlll thus be seen that an interchangeable and convertible sign element has been devised which may be emplo ed as a means for simulating electric bul sby the use of a single economize in the consumptionof current used.

What is claimed is:

1. In a sign including an apertured base, convertible and interchangeable elements adapted to be respectively illuminated by penetration and flood lighting, said elements including a transparent bulb, interengageable means on the bulb and sign base for connecting the bulb to the base in alignment with source of light to r the aperture and interengageable means with a in the open end of the bulb and on a plurality of respectively transparent and reflective plugs to. interchangeably connect the plugs within the bulbs whereby to render the bulbs convertible for flood'lighting or penetration illumination.

2. A convertible and interchangeable s gn ele1ncnt,1nclud1ng a bulb having an exteriorly threaded open end adapted for engage-- ment with a threaded support and internal threads at said open end and on a plurality of respectively transparent and reflective vplugs to interchangeably connect the plugs \vithin the bulbs whereby t0 render the bulbs convertible for flood-lighting or'penctration illumination. o

3. A convertible and interchangeable sign element, including a bulb having an exteriorly threaded open end adapted for engagement with a threaded support and internal threads at said open end and on a pluralit of a respectively. transparent and reflective p ugs' to interchangeably connect the plugs within "the bulbs whereby to render the bulbs con- Lou s 1;.
