IDENTIFICATION OR ADVERTISING DEVICE.

Application filed April 25, 1925. Serial I\To. 25,836.

This invention relates to display or advertising devices particularly adapted for insertion into illuminating devices such as the tail-lights of automotive and other vehicles.

i The housings of tail-lights afford a convenient place for insertion of a transparent or translucent disk containing advertising matter such for example as the name and address of the dealer from whom the vehicle was purchased and circular disks of celluloid are used for this purpose. as the lamp housing is devoid of means for clamping the disk or otherwise holding it against rotation, these circular discs become displaced by rotation under the influence of vibration during travel of the vehicle so that the printed matter thereon becomes inverted or otherwise disposed in position rendering it difficult to read.

The object of the present invention is to provide a disk of this type equipped with means adapted to engage the lamp-housing for holding the disk against rotation in the latter.

The invention may be variously embodied and in the accompanying drawings T have illustrated several suitable embodiments thereof. In said drawings Figure 1 is a perspective view of a conventional type of automobile tail light equipped with a device constructed in accordance with the invention, a part of the housing being broken away.

Fig. 2 is a central vertical section of the tail light housing.

Fig. 3 is a similar section of another conventional type of taillight housing equipped with a device constructed in accordance with the invention.

Fig". i is a face view of a disk constructed in accordance with the invention.

Fig. 5 is a fragmentary diametric section of a cylindrical housing equipped with the disk shown in Figure a.

Fig. 6 is a fragmentary face view of another embodiment of the invention.

The invention consists, broadly, in providing a circular disk 1 of a flexible transparent or translucent material, such as celluloid, adapted to have advertising matter or the like, printed or otherwise disposed on a surface thereof, with peripheral projections 2 presenting sharp edges and capable of being easily flexed. The disk 1 is of substantially the same diameter as the interior of the mouth of the housing 3 of a lamp t, exemplified in the conventional tail-light housings of automotive vehicles. The peripheral projections 2 will thus be flexed as the disk 1 is forced into the mouth of the housing and the sharp edges of said projections self-retained in contact or engagement with the inner circumferential wall of said mouth, exerting some pressure on the latter and thus frictionally resisting rotation of the disk 1 relatively to the housing under the influence of the vibration resulting from travel of the vehicle. The material of which the disk is made is relatively thin and it will thus take up insufficient space to interfere in any way with the mounting upon or within the mouth of the housing of the glass disk or body 4. Preferably the projections 2 project only slightly beyond the circumferential edge of the disk 1 and present side edges disposed perpendicularly to the straight outer edges thereof, the said side edges being lengthened by slitting the disk slightly, substantially radially thereof, as indicated at 5. Thus the projections; present the sharp corners 6 for engagement with the inner surface of the circumferential or cylindrical wall of the housing into which the disk 1 is inserted as aforesaid. The projections are flexed substantially shown in Figure 5, from which it will be seen that the sharp corners 6 will bear upon the surrounding surface to not only prevent rotation of the disk 1 as aforesaid but also to resist its movement longitudinally of said surface in one direction.

As shown in Figures 3 and 6, the projections 7 of the disk 8 may be substantially semicircular and the disk devoid of the cuts or slits 6.

Either of the disks 1 or 8 affords the advantage sought, the structure of Figure 1 being preferred because requiring somewhat less material.

I claim as my invention 1. A display or advertising device for insertion in a lamp housing or the like, consisting of a circular disk of celluloid or like transparent or translucent material possess ing flexibility, equipped with short peripheral projections, the diameter of the disk being substantially the same as that of the cylindrical portion of the lamp-housing and the projections adapted to be flexed as said disk is forced into said housing, to thereby cause said projections to yieldingly bear upon the surface surrounding the disk to hold the latter against rotation relative to said housing.

2. A display or advertising device for insertion into the cylindrical portion of a lamp-housing or the like, comprising a circular disk of a flexible resilient transparent or translucent material such as celluloid and corresponding in diameter substantially with the inner diameter of said cylindrical por tion of said housing, said disk including integral peripheral projections having side edges and having substantially radial short slits flush with said side edges for continuing the latter slightly into the body of said disk, said projections adapted to flex and yieldingly bear at their outer ends upon the inner cylindrical surface of said housing as said disk is forced into the same to thereby prevent free rotation of said disk.
