(Cl. Lfr- 132) 9 Claims.

My invention relates to new and useful improvements in display units.

An important object of my invention is the provision of a display unit that is uniquely constructed to permit a sign, or other printed or engraved indicia, to be observed as a series of spaced registering signs, the series being of infinite length to create an illusion of extreme depth.

Another object of my invention is the provision of a device of the above-mentioned character wherein the portion of the standard retaining the sign is rockable about a horizontal axis, whereby passersby may readily observe the sign regardless of whether the standard is disposed at eye level, above eye level, as above a doorway, or placed in a window substantially below the eye level.

Still another object of my invention is the provision of a device of the above-mentioned character that is simply yet durably constructed which permits the inexpensive manufacture thereof in substantially large quantities and which is decidedly eicient and eicacious in the performance of its duties.

Other objects and advantages of my invention,

will be apparent during the course of the following description.

Figure 8 is a fragmentary transverse sectional view taken on the line 8-8 of Figure 7, and

Figure 9 is a perspective View of one of the letters comprising a part of the sign shown in the illustrated drawings,

In the accompanying drawings, wherein for the purpose of illustration, is shown a preferred embodiment of my invention, the numeral I0 designates a standard comprising a stationary base II rockably supporting a housing I2` The entire standard may be advantageously formed from sheet metal and the base may be made of any selected shape suitable for supporting the housing. The base is here illustrated as being of substantially frusto-conical formation in both front and end elevation, and the bottom panel I3 thereof is preferably removable to permit access to be had to the interior of the base. The downwardly divergent rear and front walls I6 f and I'I of the base are provided with inturned bottom flanges I4 and I5, as best illustrated in Figure 2, to slidably support the panel I3. One end of the panel extends through a slot I8 in the base and the projecting portion thereof is preferably bent back upon itself to provide a transverse bottom shoulder I9 which may be gripped by the ngers in sliding the panel through the slot. Elongated strips 20 of felt, or the like, are adhesively, or otherwise secured, to the bottom surfaces of the flanges I4 and I5 to prevent marring or scratching of the surface supporting the standard.

The box-like housing I2 is of a length slightly less than the top of the base and includesa solid rear wall 2I, a front wall 22 having an essentially large central opening 23 and end walls 24 and 25 integrally connecting therewith. The lower edges of the side walls curve outwardly, as at 26, and the lower marginal edges of the front and rear walls are similarly arcuately curved to conform therewith. The curved lower portions of the front and rear walls extend into the open top of the base and the upper marginal edges of the rear and front walls I'I and I8 of the base are arcuately curved to snugly accommodate the same. As best illustrated in Figures 4 and 5, the ends of the housing extend slightly below the front and rear walls thereof, which extending portions are pivotally attached to the depending tabs 2'I integrally connecting with the ends of the base. The upper portions of the end walls of the housing are similarly enlarged, as at 28, and the upper marginal edges of the rear and front walls 2I and 22 are arcuately curved to conform therewith. The end walls similarly extend above the rear and front walls, which extending portions are provided with an arcuately curved edge adapted to close the opposite ends of a removable cover 29. The cover is bowed longitudinally to snugly receive the extending portions of the end walls and the opposite marginal edges thereof are provided with laterally extending guides 39 adapted to be slidably received in the inner guideways 3| of the rear and front walls.

A supporting bracket 32 is iixedly mounted within the housing at each end thereof. Each of the brackets extends the full depth of the opening 23 and is of substantially U-shaped formation in transverse section. As best illustrated in Figure 3, the side flanges of the brackets are spaced from the rear and front walls to provide channels 33 and 34 and the base 35 thereof is provided with a longitudinal medial guide 35. An opaque mirror 31 is mounted on the rear wall of the housing in confronting relation with the front opening 23 and the ends thereof are snugly received within the rear channels 33 to hold the same in pressed relation with the wall. A second transparent mirror 38 is also disposed within the housing in pressed relation with the front wall to close the opening 23 and the ends thereof are snugly received within the front channels 34 provided by the end brackets. A transparent sheet 39 of glass, or like material, is interposed between the mirrors 31 and 38 and with the opposite vertical edges thereof slidably received Within the intermediate guides 36. If desired, the edges of the sheet 33 extending into the guides may be protected by a strip of felt 49, .or the like. As best illustrated in Figure 3, the sheet 39 is disposed at substantially the longitudinal center of the housing and in equi-spaced relation with each of the mirrors 31 and 38. Suitable indicia 4I, such as the name John Doe illustrated in the drawings, is carried b-y the sheet substantially centrally of the opening 23.

If rays of light are caused to pass between the transparent sheet and the mirrors, the indicia on the sheet will be clearly seen as multiple reflections between the mirrors by a person looking through the opening 23 and through the transparent mirror 38. The illusion thus created is to the effect that there is an infinite number .of the indicia, each letter or character thereof being arranged in columns of infinite length. If either the front or rear mirror is in-clined slightly either vertically or horizontally, the columns of characters will appear to curve gradually either upwardly or downwardly or to the right or left in accordance therewith.

In order to effect proper illumination of the unit I prefer to use the Lumiline bulbs 42 though, obviously, any suitable type of bulb may be used. Sockets 43 'are mounted on each end wall of the housing above and below the brackets 32 and above and below the upper and lower edges of the opening 23. The bulbs comprise elongated transparent tubes the ends of which are closed by metallic conductors which, in turn, have a radially extending prong adapted to be received by the sockets 43. The upper bulb 42 will thus be received within the cover 29 and the lower bulb will be 'accommodated within the base Il. An outlet socket 44 is disposed within thebase and is here illustrated as being mounted on the rear wall l5. Electrical conductors 45 connect each of the sockets 43 with the outlet socket 44 and one end of the outlet socket extends through the supporting wall to receive a male plug 46 carried by the end of a suitable conductor 41. The conductor 41 leads to any sui-table source of electric current and, when properly connected, will effect illumination of each of the bulbs 42.

An arcuately curved reflector 48 is arranged below the lower bulb 42 and the opposite ends thereof are secured to the braces 49 extending transversely of the base. The reflector is spaced slightly below the bulb in a manner to reflect the light rays from the bulbupwardly and between the mirrors and the transparent sheet. As best illustrated in Figure 2, the forward edge of the reflector is spaced substantially from the front wall l1 of the base to permit the bulb 42 to also illuminate the transparent panel 51, which is detachably held by the clips 53 to close the opening 58 in the front wall. Any desired indicia may be inscribed on the panel 51, which indicia may be clearly seen through the opening 5S. I prefer that the arcuately curved inner surface of the cover 29 be coated with baked enamel, or the like, to provide a similar reflecting surface adapted to direct the rays of light from the upper bulb 42 downwardly between the mirrors and the transparent sheet.

Obviously, the indicia carried by the transparent sheet 39 may be inscribed thereby in any suitable manner, such as by painting, etching, or the like. I have, however, here illustrated the separate characters of the indicia as comprising raised letters V5l) which are preferably applied to both the front 'and rear surfaces thereof. In Figures '7 and 8 I have illustrated a suitable device for assuring the proper centering and aligning of the letters. The device comprises an essentially rectangular frame 5I the inner peripheral edge of whi-ch is bent downwardly and inwardly tol provide a supporting ledge 52. When the sheet is supported by the ledge, the top surface thereof will extend flush with the top surface of the frame whereby the rules 53 may be moved thereacross to align the upper and lower ends of the letters. Set screws 56 carried by the ends of the rules may be threaded into pressed engagement with the upper surface of the frame to securely hold the rules in a selected adjusted position. The end pieces of the frame are provided with equi-spaced markings 54 to permit each of the rules to be positioned equi-distant from the longitudinal center of the frame and each of the rules is provided with markingsl55 to facilitate the proper spacing of the characters.

It may thus be seen that I have provided a display unit which creates a unique and attractive optical illusion. When the bulbs 42 are illuminated, the indicia on the transparent sheet 39 and on the transparent panel 51 may be readily observed by a person standing in front of the unit. The panel 51 will appear as a conventional illuminated sign kand the indicia on the sheet 39 will have an appearance of extreme depth. By reason of the multiple reflections obtained between the front and rear mirrors 38 and 31, the characters on the intermediate sheet will be reected back and forth and the multiple refiections thus obtained provide a display which will readily attract the attention of passersby. The unique construction of the support will permit the unit to be positioned at eye level or substantially above or below eye level. By rocking the housing I2 about its pivots, the housing may be tilted either forwardly or backwardly in a manner to best present the indicia to the passersby. The middle sheet 39 is easily removable when the cover 23 and upper bulb 42 are removed which unique construction permits the display to be changed at regular intervals and with a minimum expenditure of time and effort.

It is to .be understood that the form of my invention, herewith shown Yand described, is to be taken as a preferred example of '.the same, and that various changes in the size, shape and arrangement of parts .may be resorted to without departing from the spirit of my invention, or scope of the appended claims.
