It will 00 ing, having a. series of apertures arranged in any therefore be seen that light reflecting units conpreferred manner and having inserted therein structed in this manner can be conveniently and improved light reflecting units with securing rapidly assembled in position upon a sign plate parts thereon adapted to cooperate with said wall to complete the sign, without the use of tools or to prevent withdrawal of the unitstherefrom. other devices, whereby the cost of constructing A further object of the invention is to provide the sign is considerably reduced.

The sign shown in Fig. 1 of the drawing by way of illustration may comprise any suitable display plate or background provided with the desired number of light reflecting units or elements arranged in any preferred manner, and corresponding to characters of any preferred design.

The element Ill may comprise a housing or the front wall or display plate of a complete sign, or one section of a sign formed of a plurality of such elements. Where the element is constructed in the form of a housing it will serve to enclose the portions of the light reflecting units projecting rearwardly of the front or display plate through the openings ll therein. The light reflecting units are designated generally by the reference character l2 and include a suitable lens [3 extending within a casing I4, the lens being provided with suitable reflecting means within the casing not shown. The lens casing is provided with a flange or shoulder l5 at the front end thereof which is adapted to engage the front side of the plate to limit rearward movement of the light reflecting unit when positioning it within the aperture of the plate.

The casing [4 of the light reflecting unit as provided with a threaded extension I6 which is projected through an opening in the end wall ll of a cup-shaped holding member l8 sleeved on the lens casing M, as best shown in Fig. 4. The front end of the cup-shaped member extends within the aperture l l of the plate l0 and engages the flange or shoulder l of the casing against which it is urged by the clamping action of the nut 19 on the threaded extension IS.

The means for securing the light reflecting unit on the supporting plate III, in one disclosure, is carried by and preferably formed integral with the holder l8 for the light reflecting unit, said means comprising the outwardly extending yieldable tongue-like parts 20 preferably formed by slotting the holder longitudinally and transversely thereof and bending said parts to cause them to project outwardly from the sides of the holder as best shown in Figs. 5, 6, and 7. It will be noted that the securing parts 20 are of tapered construction and that they are substantially of the same curvature as that of the cup-shaped member from which the parts are formed. The front edge of the securing member is preferably serrated to provide it with a series of teeth 2 I, the extremities of which lie in a plane inclined to the plane of the supporting plate It, as indicated in Figs. 3 and 4. The rear edge 22 of the securing member is also in a plane inclined to the plane of the supporting plate l0 so that it constitutes in effect a cam, which when the light reflecting unit is inserted within the aperture of the supporting plate will be engaged by that portion of the plate surrounding the aperture which will cause the securing member to be cammed inwardly toward the lens casing. When, however, the light reflecting unit has been moved to final position with the flange I5 of the lens casing in engagement with the front side of the supporting plate the deflected resilient securing member will spring outwardly, at which time one of the teeth of each of said members will engage and interlock with the portion of the supporting plate at or adjacent the rear side thereof, whereby the light reflecting unit will be securely retained on the plate and held against withdrawal therefrom. Furthermore, the pressure exerted by the resilient securing parts 20 on the plate I0 is sufficient to firmly clamp the flange [5 of the light reflecting unit in engagement with the front face of the supporting plate whereby the unit is held properly centered within the aperture of the plate.

By reason of the inclination of the front portion of the securing member 20 to the rear face of the supporting plate [0, said securing member will accommodate itself to plates of different thicknesses, within certain limits which is advantageous since it avoids having to make up different securing devices for different signs constructed of plates of varying thicknesses. In other words the light reflecting units are made interchangeable for use with-signs having display plates of different thicknesses.

It will be understood that the teeth 2| of the securing member 20 may be omitted, in which case the unbroken front edge of said member will engage the rear portion of the supporting plate, and since said edge extends at an angle to the face of the plate a wedging action will be afforded between said parts, due to the tendency of the securing member to spring outwardly to normal position, this being true also where the securing member is serrated as shown in Fig. 6. The wedging action of the oppositely disposed securing members will operate to urge the flange l5 of the lens casing in engagement with the front face of the supporting plate whereby the light reflecting unit will be firmly held in position on said plate.

In addition to the securing members 20 of the light reflecting unit, the holder I8 is provided with outwardly struck yieldable tongues 23, the front edge portions of which may either be parallel to the rear face of the supporting plate, as shown, or inclined relative thereto, as are the front edges of the securing parts 20. The tonguelike members 23 are provided for cooperation with a supporting plate which may be slightly thicker than one of the maximum thickness which the securing members 20 are designed to accommodate. The securing parts 23 like the parts 20 will prevent withdrawal of the light reflecting units outwardly through the apertures ll of a supporting plate of a predetermined thickness. Furthermore the securing parts 23 will be deflected inwardly by said supporting plate and will pass through the aperture therein and spring outwardly to the position shown in Figs. 3 and 4 to prevent subsequent withdrawal of the light reflecting unit from said plate. The light reflecting units may, however, be released for removal from the supporting plate merely by unscrewing the nut l9 and withdrawing the cupshaped holder I8 from the unit.

In the modification shown in Fig. 8 the principle of operation of the securing parts for the light reflecting units is the same as that described above in connection with the disclosures of Figs. 1 to 7, inclusive. However, in this arrangement the cup-shaped holder is omitted, and likewise the screw extension of the light reflecting unit, said unit being otherwise the same as that shown in Fig. 4. 'The light reflecting unit of Fig. 8 comprises the lens I 3a and the casing a therefor,-

having-a flange |5a for limiting the movement of the unit rearwardly within the aperture Ha of the supporting plate Illa.

The securing means for the light reflecting unit of said-modification preferably comprises a continuous ring or band 24, encircling the front portion of the lens casing in abutting relation with respect to the flange I5a thereof and may be de tachably or permanently secured on the casing as preferred, by any suitable means, as, for example, by one or more pins anchored in the wall of the casing I la in engagement with the rear edge of said band which is prevented from rotating on the lens casing by said pins. The

band is formed of resilient or spring-like material and is provided with a pair of oppositely disposed outwardly struck securing members 26, similar to the securing members 20 of Fig. 6, except that the teeth of the latter have been omitted.

, the plane of the supporting plate Illa. The rear engaged by the portion of the plate surrounding the aperture wherebythe securing member will be cammed inwardly toward the lens casing. As

' soon however as thu light reflecting unit'is moved to final position, with the flange l5a in engagement with the front face of the supporting plate, the securing member will spring outwardly to operating position, in which a portion of its front edge will become wedged into engagement with the rear portion of the supporting plate to clamp and hold the light reflecting unit in position upon said plate. The band 24 is also provided with outwardly struck resilient tongue-like portions 29 corresponding to the tongue-like members 23 of the cup-shaped member I8 and provided for thesame purpose.

In applying either of the light reflecting units described herein to the supporting plate, all that is necessary is to insert them within the apertures provided therefor and at the same time move them rearwardly to final position, .an. operation which can be quickly performed, whereby the time required in assembling and securing the several light reflecting units upon the display plate of the sign is reduced to a minimum. However, in thus applying the light reflecting units to the supporting plate they can, if desired, be given a retating movement coincident with the operation of pushing them into position within the openings of said plate.

As previously stated, one advantage of light re- I fleeting units constructed as shown and described herein is'the saving in time and cost of labor afforded by reason of the fact that no parts have to be applied to the units to secure them upon -the display plate after they have been positioned in the openings thereof as had been necessary heretofore in signs of this type.

A very considerable saving in the cost of producing the signs is also afforded by reason of the novel method of constructing and applying the individual light reflecting units thereto. This is true since the light reflecting units, are applied to a single supporting plate, whereas in previous designs it has generally been customary to mount the units on a least two or three supporting plates. The omission of such additional plates from the present design and the parts associated therewith for securing the light reflecting units thereon,'makes it possible to greatly'economize, both in thecost of materials and labor, as will be apparent for the reasons stated.
