ZED/811161, fiamm Patented Mar. 14, 1939 UNITED STATES PATENT OFFICE 2,150,748 nrsrmr DEVICE William 8. Pearson, Park Ridge, 111., asslgnor to Peel-co, Inc., Park Ridge, 111., a corporation of Illinois 4 Claims.

The present invention relates to display devices and has been developed with a view to displaying house numbers or other symbols before a reflecting background, capable of being illuminated at night.

The principal object of the invention is to produce an article of the kind mentioned which may be manufactured economically and which will be at the same time durable and effective in service.

The preferred embodiment of the invention is presented in the following detailed description and the accompanying drawing, while the scope of the invention is set forth in the appended claims.

In said drawing, Fig. 1 is an elevation of the display device constructed and arranged in accordance with the present invention. Fig. 2 is a plan view of the device with the panel on which it is positioned shown in horizontal section, the position of the section being indicated by the line 2--2 of Fig. 1. Fig. 3 is a partial sectional elevation through the center of the device, the plane of section being indicated by the line 33 of Fig. 2. Fig. 4 is a perspective view of one of the symbols carried by the device, the same being the numeral 4. Fig. 5 is a plan view of a portion of one of the clamping strips showing its initial curvature when not in clamping position. Fig. 6 is a vertical section through the base of the device, the plane of section being indicated by the line 66 of Fig. 2. And Figs. 7 and 8 are detailed sectional views showing how the base and face strip fit together, the planes of section being indicated respectively by the lines 'l'l and 8-8 of Fig. 2. Throughout these views like characters refer to like parts. In some instances also parts are broken away or slightly separated to show details of construction.

The new device, as set forth in the present embodiment, includes a shelf-like base A, a support B against the face of which the base member bears, a lamp socket C located in the center of the base, an outer face plate or strip D which is secured at its lower edge to the outer upper portion of the base, a cooperating clamping strip E, one or more symbols F, in the present instance in the forms of numerals, held in place between the strips D and E, and an electric lamp G positioned in the socket C. These several parts are positioned, as clearly illustrated, so that the symbols stand out away from the face of the support and the latter serves as a reflecting surface. By makin the symbols black and the surface of the support light, the symbols stand out clearly and are easily read from a considerable distance. In the RElSSUED ov 2 6 i940 daytime, the light surface of the support serves to set of! the dark symbols. At night, the lighting of the lamp illuminates the surface of the support and the same result follows.

The base A comprises central, intermediate and outer portions. These are arranged in different steps or elevations, rising as one proceeds, either to the right or the left from the center, where the lamp socket is located. The central portion has a bottom l and an arcuate wall II. The arrangement makes the floor l0 practically a segment of a circle. The intermediate portion has a bottom I2 associated with a wall l3. The wall has arcuate portions at its ends and a central straight portion as clearly illustrated in Fig. 2. The wall ll of the central portion merges into the inner edge of the floor 12 of the intermediate portion, as clearly illustrated. The outer portion of the base includes a floor l4 and a wall IS. The inner edge of the floor I 4 merges into and forms a continuation of the upper part of the wall l3 of the intermediate portion. The walls [3 and I! come very close together along the central portion of the base but are separated at the ends so that the floor i4 is practically divided into two end portions with a narrow connecting strip between the two.

The upper edge of the wall I is provided at intervals with upright projections Hi. There are five of these uprights l6. Three are spaced along the forward edge of the base, and in addition there is one at each end of the base adapted to lie adjacent to the face of the support B. Each of the projections I6 is provided with a groove ll. These grooves serve as seats for the lower flange of the face strip D. Along the top of the wall l5, at points between the uprights I6, the surface is divided into two parts, one elevated above the other so as to provide vertical shoulders l8. These shoulders [8 are in line with the bottoms of the grooves l'l. When the face strip D is in place, then its lower flange will enter the grooves ll of all of the projections l6 and at the same time bear against the shoulders I8 formed upon the top edges of the walls l5. As clearly shown, the front edge of the base is practically parallel with the rear face and at its ends the same is neatly curved. With the construction described there is a seat provided throughout the length of the wall l5. This seat, as noted, is for the lower'flange of the face strip D.

At the center of the lowermost floor II) a cylindrical pocket I9 is provided. As we shall see later, this is for the lamp socket C. Along the open or unwalled edges of the floors l0, l2 and M are Qii provided slight thicknesses in the form of beads 20. Similarly, along the edges of the vertical walls II and I2 there are provided similar thicknesses in the form of beads 2|. Preferably the entire base A is moulded in one piece, and for the purpose Bakelite or a similar material is preferably employed. It may also be noted that at one edge of the fioor id of the base A there is a portion 22 which is thinner than the rest of the floor ID. This is provided as a weak portion which maybe broken out for the purpose of providing an opening for the passage of conducting wires on their way to the lamp socket terminals. In all installations such a passing of the wires need not be had. As we shall see presently, they may be passed through other openings. It will be seen that when the base A is placed with its open side against the face of the support B there will' result a shelf-like structure with several depressions which gradually increase in depth toward the center.

The support B may take different forms. In the present instance it is illustrated as a flat slab or panel of wood or other like material against the face of which the base A is positioned. Instead of employing a separate panel B, the sup port B may be part of the structure on which the device is mounted. Thus, for example, if the number be placed on a residence above the door, the support B may be the llntel or other portion of the door frame. Whatever the part which constitutes the support B, its surface should have a light color so as to set off the symbols F. Thus, if the support be wood it may be painted white or given a color which will serve as a good reflector, both when the lamp G is illuminated and when the device is used in the daytime with out lamp illumination.

The cylindrical pocket I9 at the center of the base A receives the socket C, which, as usual, includes a shell member 25 and a central terminal 26, suitably insulated from each other. As shown, the shell member is electrically connected to a wire 21 and the central terminal 26 is electrically connected to a wire 28. The lamp G has the usual shell and tip construction by which circuit is completed through the filament of the lamp whenever the lamp is properly positioned in the socket. The wires 21 and 28 may be passed out of the socket insulating shell is in different ways. As before noted, this might be by way of the opening provided by breaking out the thin portion 22 of the base floor l0. Again, it may be done as illustrated in Fig. 3 by passing each wire through an opening in the cylindrical wall of the chamber l9 and thence out through a single opening 29 in the support B. These wires are connected to any suitable source of electricity. Ordinarily the lamp G is of low voltage and the commonly supplied current is reduced to the desired voltage by a suitable transformer.

Coming now to the face strip D it will be noted that the same has an outline in plan similar to that of the forward upper edge of the base A. This strip has a central body portion 3! which terminates in an upper flange 32 and a lower flange 33. It is this lower flange 33 which is fitted into the grooves l1 and against the shoulders l8 of the base A, as before mentioned. Besides having these upper and lower flanges the strip D also has inturned flanges 34 at its opposite ends. The face strip is composed of metal and because of its curved ends has a slight yield which permits of its being easily slipped into place upon the base A. A very slight movement ensures of the face strip D will serve to spring its end flanges 35 around the adjacent faces of the projections it at the ends of the wall it oi the base A. 7

When the base A and the face plate D are assembled, and the structure is placed against the face or the support B, it will be obvious that with a lamp, such as the lamp G, in use, the light from the latter will be cut on at the front of the device by the strip D and a certain amount of it will be cut off at the ends of the device by the same strip. On the other hand, the light rays will be free to pass upward over the face of the support B. In this way the face of the support above the device is clearly illuminated. As the light passes out over the end portions of the structure there will be clear lines of demarlration between the upper light portion and the lower darker portion, such as indicated by the lines 35 and 36 in Fig. 1. Because of the nearness of the lamp G to the face of the support B those rays which travel upward and lie between the lines 35 and 38 will gradually lose their intensity and at some distance from the device, if the extent of the reflecting face of the support B is suflicient, there will result a change from the light surface to the more distant dark surface. This change will be gradual and there will be no distinct line of demarkation between the two, as in the case of the side lines 35 and 36. The fanlike display of light thus produced behind the dark symbols greatly augments the beauty of the device.

The face plate D is provided with a plurality of holes 31 through which retaining members 38 may be passed into engagement with the support B. In the present instance these members 38 are in the form of headed bolts which pass through openings in the base B and are threaded for the reception of nuts 39. By screwing up the nuts the assembled structure may be firmly held together. In other words, the base A and the face strip D will be held in position against the support B.

Next we come to the retaining strip E which cooperates with the strip D to clamp the symbols F in place in the device. As clearly shown in Fig. 5, the strip E has a given set so that its center bulges outward. This is provided so that when the strip is put in position in the device with symbols F in place the central portion of the strip will bear against the centrally disposed symbols with that degree of pressure which will hold the central symbols as firmly as the others. As clearly shown, the ends 42 of the strip E are arcuate and free of any transverse grooves or projections. In. contrast to this, the center 43 of the strip is bent at its upper edge so as to provide a flange 44 which extends substantially at right angles to the portion 43. When assembling the strip E into the structure, the ends 42 abut at their extremities against the flanges 34 of the face strip D. As we shall see presently, the intermediate flanged portion of the strip bears against the rear sides of thesymbols F. The strip E is sufficiently flexible although made of light spring metal to be slipped into place as just described after the various symbols have been set in position.

The symbols F may take various forms. Ordinarily, where house numbers are to be provided, a number of stamped up or moulded numerals are prepared and then the appropriate ones are placed in position between the strips D and E, ac-

cording to the place where the device is to be used. In the present instance the house number is "1943". Each symbol is provided at its lower end with a projection 41. Upon the forward side of this projection are a number of spacing studs 48. These might be quite different in form than shown, since their only purpose is to space the top and the bottom of the projection 41 with respect to the face strip D. As shown, these projections abut against the rear of the face strip and the upper flange 32 of the face strip is engaged by the upper pair of studs 48. On the opposite side of the projection 41 is a groove 49, just above a transverse projection 50. The portion 5| below the projection 50 is cut away so as to lie in the plane of the bottom of the groove 49, all as clearly illustrated. The retaining strip E serves to engage this latter face of the projection 41, the flange 44 entering the groove 49 and the flatter portion 43 of the strip engaging the portion 5| of the projection.

It should also be noted that preferably the retaining members 38 are positioned so that when the strips D and E are assembled theupper edge of the member 38 in each instance will engage the under edge of the strip E. This fit insures pressure of the uppe; studs 48 against the flange 32 and thus insures a grip upon the symbols which will hold them in proper position. The two upper studs, by engaging the flange 32, hold the symbol against rocking. Rocking is also prevented by the flange 44 entering the groove 49. The engagement of the flange 44 in the groove 49 also holds the symbol up in place. While thus holding the symbols in proper elevation, the clamping strips D and E do not prevent their being shifted laterally so as to properly center them with reference to the face strip D or the device in general.

The symbols F, like the base A, are preferably moulded out of Bakelite or similar material. The result is a series of dark symbols separated from the dark base A by the face strip D which is composed of metal and is preferably bright, either by reason of the use of stainless steel or because nickel plated, chromium plated, or otherwise treated. The general effect is therefore quite attractive.

The lamp G is an electric lamp preferably of low voltage, say 6 or 8 volts, and when screwed down or otherwise operatively positioned in the socket C, is preferably protected from the weather by a ring or gasket of rubber, designated 52. This gasket is pulled down as a sleeve over the cylinder IQ of the socket structure and its upper end is closed in around the lamp G and yieldingly bears against the same, thus providing a watertight and weather-proof covering by which the lamp connections are amply protected.

It will be apparent that the device may be varied in construction in certain particulars without departing from the spirit and scope of the invention. Accordingly; it is my aim to cover such changes by the terms of the appended claims.

Thus, in respect to alterations and modifications, the number of lamps might be varied. 0bviously, with a base of considerable length a plurality of lamps might in some instances be desirable. They might also be variously positioned upon the base A. Again, although I have shown the symbols F in an upright position, that is to say, with the symbols uppermost, it will be understood that the entire device might be inverted, and the symbols placed lowermost. In such event, the latter of course should have their projections 41 differently positioned upon the symhole so as to leavethe latter, when mounted, in proper position for reading. In other instances, the base A and the associated parts might be mounted with the long dimension vertical and the symbols positioned at the side, again, the symbols having their projections suitably changed in position, as will be obvious. In this connection it should be pointed out that the claims are drawn so as to read upon the device when it is positioned with the symbols uppermost, as illustrated. Hence, the directional words found in the claims, such as upper, "lower", "downward, vertical, below", upright, "elevation and the like, properly deflne the relation of the various parts when held in one position, although that may not be the position in which it is ultimately mounted. The functional advantages are the important ones although direction cannot in itself be wholly disregarded.

It should also be noted before concluding this description that the symbols F may be readily interchanged or replaced. This is done by disengaging one of the ends 42 of the strip E from its engaging flanges 34 on the strip D. By simply inserting the end of a screw driver behind the end 42 and bending the end by pressing against its outer side, the same may be moved free of the flange 34. When the strip E is once removed the symbols may be interchanged among themselves or removed entirely and new ones, or fewer ones, put in their stead. When the symbols are newly assembled, the strip E may be putback in place in its holding position just as before described.
