Application filed April 4, 192?.

The subject matter of this invention is a sign, and more particularly a sign of the type adapted to be illuminated, either the whole of the time it is in use or only a part of the time, as dictated by the requirements of particular conditions.

It is the aim of the invention to produce a sign wherein the source of light, which may be disposed along one edge of the sign, is reflected at the sides of the sign in a manner to effect an even or uniform illiunination of the sign. In other words, it is the aim to produce a sign which will not show bright spots or dark spots as a result of nearness or remoteness from the light source. it is a further object of the invention to provide such a sign which can be +asily and economic: lly maluifactured and assembled, wherein aminiu'uun number of parts are used and wherein some of the parts function in a dual manner, as for instance, a part which functions both as a reflector and as a meml'ier for assisting in holding the several parts of the sign assembled. A further feature of this invention is the manner in which the sign structure is constructed, and the several parts assembled so that all of the joints are tight fitting and dust proof. Notwithstanding this arrangement, however, the invention contemplates provision for circulation of air so that heat generated by the light source may be dissipated.

In the accompanying drawings, a satisfactory form of the invention is shown:

Serial No. 180,735.

The sign shown in the drawings is of the type for interior use; that is, use within other buildings, theaters, and the like. The body of the sign is made up of a framework or casing, which includes a top molding 1, end panels 2, and a bottom 3. A removable cover 4; closes the upper end of the molding, and the cover may be provided with a suitable opening and bushing for the passageway therethrough. of a cable 5 for conducting an electric current. The cover may be also provided with openings 6, :in order to permit circulation of air so as to prevent overheating of the device from the heat generated by an electric light. The molding is adapted to provide a light compartment. As shown .in Fig. 4-, the cover is provided with a bracket 7 positioned ad jaceut the bushing through which the cable passes, and this bracket is designed to hold a socket (not shown) which in turn holds a light bulb 8. In practice, it has been found satisfactory to use a light bulb of considerable length so as to extend well along the length. of the sign. The cover is also provided with a reflector 9 which, as shown in Fig. 3, lies imn'iediately above the light bulb. The reflector may be soldered to the cover.

The framework of the sign structure thus described is designed to receive and hold a sign panel 10 which may be of glass provided with the desired. indicia which may be put .in the glass by a sand blasting process. A second panel 11 (l? 8) may be carried by the frame, and where desirable this panel may include sign matter, or .it may be left blank with no indicia thereon. This, of course, depends upon requirements of the particular installation.

lVithin the sign casing and at the bottom thereof is a reflector and holding device 15, and as will be noted by referenct-i to Fig. 2, this device runs substantially the entire length of the iasiug and is just enough slmrter than the casing to permit it to be easily inserted. This member is made of relatively thin sheet metal. and may be advantageously shaped as shown in the drawing. This member may be tinned or simi larly treated so as to have at least one side thereof of a light reflecting nature, thus 7 similar material to the member 15.

is a reflector and holding device 18, which is constructed in a manner similar, and of These members thus provide reflecting surfaces 19 and 20 at each end of the casing. Preferably, these members have their ends turned over as at 9.1, so as to lie in behind the ends of the panels and 11 so that theyare securely held in place. A strip of angle material 22 is placed along the upper edge of each panel. These strips are disposed so that their end parts lie between the panels,

and the end members 18. Also, these angle members project outwardly far enough to overlie the adjacent shoulder of the sign molding, as shown at 23, thus closing the crack between the panels and the sign frame to keep the elements, dirt, and dust from entering into the sign and light compartment.

In producing the device it will be understood that the sign frame and its cover and the glass panels are made up separately. In addition to these pieces, it is necessary only to make up the bottom member 15, the end members 18, and the angle members 22, all of which are easily produced by stamping or rolling the sheet metal. In assembling the sign structure the bottom member may first be put into place, and then the two panels, whereupon the end holders and reflectors may be inserted between the panels. Then the angle members may be positioned along'the upper edges of the panels. The bottom and end and reflectors are made of metal possessing some spring qualities, and they are designed to press outwardly against the panels thus to hold the panels tightly against the adjacent frame members. Thus, the panels are held securely in place and prevented from moving or rattling within the casing. Moreover, the angle strips act as reinforcements so that the upper edge of the panels are held outwardly against the frame.

By reference to Fig. 3 it will be noted that the covertor the sign sets tightly within the molding and rests upon a horizontal shoulder in the molding. This cover makes a nice fit in the molding and prevents the entrance of dust. It will be noted that the side panels are held snugly against the frame structure on all four sides. The angle strips and the out turned edges of the reflectors cooperating to make dust tight joints all around. 7

By again referring to Fig. 3 it will be noted that the reflector Q is secured to the top in such a way as to provide spaces between the reflector and the top, and the holes 6 in the top communicate with these spaces. Thus while air circulation ispermitted between the reflector and the top and let out through the holes, yet the arrangement is such as to prevent any light from shining upward out through the holes which would be undesirable and destroy the niccty ol the sign. Likewise, dust which may enter the holes will, in the main, settle on the back ol" the reflector and will not pass into the main interior of the sign.

In Fig. (i a slightly modified form is shown, and in this form the top molding is rounded outwardly as at and the edge of the molding material is turned upwardly at 231. lVith this type of molding, securing strips 32 which are U-shaped in cross section, may be used. The interior of the sign structure is otherwise the same as the form shown in Fig. l. and the assembling is the same. However, the U-shaped strips soeurely fix the upper edges of the panels to the inti'irned edges 31 ot the frame structure and also form a very ellicient dust prool' joint. It is noticeable that the removing oil the interior parts of the sign structure is as easy as its assembly. Accordingly, the sign frame may be made up along standard lines and any sort o'l'i a sign panel can be used. If at any time a particular sign has been used, and it is desired to change the indicin, the panels and the reflectors may be taken out and the sign may be reassembled with new panels, all. of which is a vcry simple operation and speedily accompl shed.

By reference to Figs. 7 and S reflector members of difl crent shapes will be seen. In Fig. 7 the reflector member is provided with a relatively sharp angle Z33 thus providing reflecting surfaces 34!: which 'are at a greater angle than the type (it the reflector shown in Fig. 8. In the. use of the difl'crcnt reflectors, assume that Fig. 3 has a sign including one word as shown in Fig. 1. Here it is desirable to have the greatest illumination along the center of the panel to illuminate theindicia and the reflectors shaped as shown in. Fig. 3 do this nicely. Again assume that the structure of Fig. 6 as a side panel correspomling to that shown in Fig. 5. Here we have two words one arranged above the other and by using the bottom reflcctor as shown in llig. 7 a bright spot, so to speak, is thrown on the lower word Room. The upper reflector in the coycr is arranged correspomlingly to illuminate tho. upper word Check. The reflectors are interehangeablc so that the proper light ell ect can be had tor any type ol. sign panel.

The use oi reflectors to properly position bright spots or to eliminate bright spots where necessary is especially desirable. where the panel as a whole is not opaque, as for instance the glass having a red tint and designed to permit the passage of a certain amount of light through all portions of the u (Al panel. The bright spots or bright portions, appear through the red glass.

The reflector in Fig. 8 has a curved reflecting surface 85. This retlector has re fleeting surfaces which are not so abrupt as the form shown in Fig. and is especially adapted for use with. light tinted. yntnels so that an even distribution ot light is thrown over the panel so as to give the panel a uniform appearance.

It will be noted that all of the interior pieces of this sign are made up of sheet metal pieces which are so arranged as to act as reflectors and holders with a glass panel, and that allthe parts including the glass anels are held securely within the sign casing without involving any soldering, weld.- ing, or similar operations.

The sign shown an d described is one which may carry indicia visible :troin. opposite sides. Sometimes it may be desirable or necessary to have the indicia visible from. but one side only, in which case the panel 11 need not be of glass, and may, indeed, be

of metal embodied directly into the sigi'i casing.
