Filed April 23. 1928 uarantor fiaa d/as. 'ora m' attorneys Patented May 26, 1931 UNITED STATES DOUGLAS B. GORDON, 0F HAMILTON, ONTARIO, CANADA DISPLAY DEVICE Application filed April 23,

This invention relates to display devices and has for an object the provision of a device provided with a reflecting surface upon which certain symbols are projected from a l transparent sheet of material.

Another object is to provide a display device wherein the symbols to be projected are preferably out of the line of vision of the person viewing the device.

Still another object is to so arrange the reflecting surface with respect to the symbols that the reflected images will simulate the real symbols in upright positions.

With the above and other objectsin view, the invention consists in certain novel fea tures of construction, combinations and arrangement of parts as will be more fully described and particularly'pointed out in the appended claims.

In the drawings:

Figure 1 is a perspective view of a display device constructed in accordance with the present invention V Figure 2 is a fragmentary view of a portion of the display device shown in Figure 1; and

Figure 3 is a vertical section through the device.

Generally the device comprises an open face frame in the top of which is supported a transparent sheet carrying the symbols to be displayed, while a second sheet having a reflecting surface is positioned below the transparent sheet and at an angle thereto, the arrangement being such that the light from above will not only project the symbols upon the reflecting surface but will do so in such a manner that the images will assume upright positions.

Specifically the device comprises an open face frame 10 having end walls 11 and 12 respectively and an inclined longitudinally extending wall 13 joining the two end walls. Each end wall is provided with an inwardly projecting flange 14 at its top edge while a strip 15 is secured to each wall and is spaced from its respective flange 14 to form therewith a guideway 16, the rearend portion of each strip being bent toward the flange to formastop 17 Preferably a second set of strips 18-are secured to the end walls below 1928. Serial Nof272,203.

the first mentioned strips, each strip 18 being spaced above an end of the inclined wall 13 to form therewith a second guideway 19 on the end wall. Each strip 18 is likewise provided with an end portion which is bent toward the wall 13 to provide a stop 20. 7

With the above arrangement, there is provided an upper pair of horizontal guideways within which is adapted to be supported, a transparent sheet of glass 21 upon which suitable symbols 22 are formed by applying a coat of paint 22 to the glass and thencutting the preferred symbols into the paint. The lower pair of inclined guideways 19 is adapted to receive a sheet of material 23 having an inclined reflectingsurface, both sheets being detachably secured in place by means of channel shaped finish strips 24 and 25 respectively which encase the outer edges of the sheets. These strips 24 and 25 are secured to the frame 10 in any desired manner such as by fasteners 26. To provide a neat appearance finish strips 40, 41, 42 and 43 of U cross section are used to conceal the edges of the metal above the glass 21. "As shown, the strips 40, 41 and 42 each embrace the edges ofthe top wall of the frame 10, whereas the strip 43 has an extension 43 secured in and carried by the strip 24. j j

With the device as thus constructed, it will be apparent that ifit is placed in a position where the transparent sheet is exposed to daylight, the symbols will be pro ected upon the surface 23 insuch a manner thatthe reflected images assume positions disposed at right angles to the real symbols. In use the device is adapted to be displayed with the open face directly in the line of vision of the person viewing the same. In this position the transparent sheet will be horizontally disposed and usually out of sight with the reflecting surface at an acute angle to the latter, whereby the reflected images will assume vertical positions and appear to stand up from the reflecting surface,

The reflectingsurface is shown in the present instance as being disposed at an angle of 45 to the transparent sheet and inthisposi- 7 tion the reflected images will be the same size as the real symbols. It is of courseievident that by changing the angle of the reflecting surface from the reflected images will appear either taller or shorter than the real symbols according to the direction in which the surface is shifted. It will also be apparent that my display device may be used at nightsaszwellisas'inmthe day time'by positioning -aqsource of illumination above the transparent plate and to one side thereof.

iVhile the above described frame is shown as the preferred form of supporting means for the sheets, it is of course evident that any desired means may be employed for positionobtain the required results. With the present construction, should either of'the sheets be broken-or if it isldesired to substitute new sheets, it 'willi'be necessary only to remove one or :the other of the: finish strips 24: and 25;sli pput the :sheet in=question, sliderthe new sheet into'pla ceand thensecure its respective finish 'strip'to-theframe:

Fronithe foregoing it will be apparent that I have-provided a display device which may be-used inwinany different ways for display and advertising purposes, this device being sin1ple-in design and "economically manufacturedd While it is believed that from the foregoing descriptiomthe nature-and advantages of the-'invention will be readily apparent, I de sire to-have itunderstood that I do not limit myself to what is herein shown and described and th'atsuclrchanges may be resorted to when-desiredas fall? within the scope of what is claimed;
