14 Claims. 1

This invention is concerned with changeable display signs of the type described in U. S. Patent No. 2,224,069. r

The principal object of the invention is to provide a sign which is composed of a few structurally simple and easily manufactured parts, essentially only two parts, which may be assembled to form signs of different sizes and display capacities. r

' This principal object is realized by providing (a) a simple mounting member which may be furnished in desired length, depending on the height of a given sign, to form a desired plurality of horizontally spaced uprights, depending on the length of the display background surface of the sign, for removably mounting thereon (b) a plurality of panel-like background members each forming a portion of the background surface and all but one of said background members also forming carrier means for removably mounting thereon symbols to form a desired message.

The term symbols. is intended to refer to letters or characters such, for example, as disclosed in U. S. Patent No. 2,048,040.

Details of the invention will appear from the description which will. presently be rendered with reference to the accompanying drawings.

In these drawings,

Fig. 1 is a diagrammatic elevational front view of a display sign made in accordance with the invention;

Fig. 2 shows the sign of Fig. 1 with theborder or frame and also the symbols removed and some of the background panels broken away to show underlying portions of .one of the upright mounting members. I H i Fig. 3 illustrates a top View of the interior structure of the sign,- as seen when looking in the direction of the arrows along lines 33 in Fig. .2;

Fig. 4 represents an exploded perspective fractional view of parts of the sign shown in Figs. 1 to 3;

Fig. 7 illustrates an exploded view of another embodiment;

Fig. 8 illustrates a sectional view through asign analogous to the View shown in Fig. 6, but having adapter means for accommodating symbols of different structure, namely, lug type symbols; and

Fig. 9 represents a sectionalview through one of the background panels-which may be equipped parts of with an adapter for supporting symbols of the lug type, as indicated, in Fig. 8. v I

The sign shown in Figs 1-4 and Fig. 6 comprises a plurality of stripor panel-like background members 11-15 and 16-20, respectively. The inner ends of these background members abut along the line 21 approximately in the center of the sign. Each of the background member 12-15 forms an angularly forwardly tilting carrier ledge, as indicated by numerals 22-25, and each of the background members 11-20 forms a similar angularly forwardly tilting carrier ledge, as indicated by numerals 26-29.' These carrier ledges likewise abut along the line 21 approximately in the center of the sign, thus forming horizontally continuous lines or ledges for supporting desired letters, characters of other symbols to form a desired message. I 1 f Some; of these symbols may be larger than others. In Fig. 1 it is assumed that the letter W, marked by numeral 30, is the largest, extending over the four lines or carrierledges 22-25 of the background panel members '1 2-1 5, while the remaining letters or symbolsare somewhat smaller, each extending over only three carrier ledges or lines, namely, over the three carrier ledges or lines 23-25 of the background panels 13-15 at the left side of the center line 21 and. over the corresponding three lines or carrier ledges 21-29 formed by the backgroundpanels 18-20 at the right side of the center line. 'The size of the letters or symbols shown in Fig. 1 is intended only to give an example, because it is understood of course that the letters or symbols may be of different size, and some or" them may cover-only two of the carrier ledges, others three, and still others four, while it is also possible that some of the symbols, for example, such as a comma or a period, may be suspended from only one of the carrier ledges. Each symbol or letter has rear-,- wardly extending flanges which are angularly slotted as indicated in Fig. 6 in connection with letter W marked by numeral 30. d

A marginal border or frame comprising longitudinal top and bottom sections 31, 32 and the end sections 33, 3 1 is provided in order to present a neat and finished appearance. Portions of. the frame may be formed by means carried by the top and bottom panels, respectively. as will be presently described.

The sign may be disposed as desired, e. g., in a recess in a Wall or on the front surface of a wall.

There are provided forthis purpose a number of cross-sectionally, generally U-shaped channel members 35, 36, .31. which aresuitably secured to J the supporting structure by means of their flanges. These channel or upright mounting members are alike, and a description of one, namely, the centrally disposed upright mounting member 36, will suflice for all.

Referring particularly to Figs. 2, 3 and 4'. Each upright mounting member forms a plurality of pairs of a'ngularly forwardly projecting ledges such as 38, 39 and 46, one pair of such ledges for one end of each of the panel background members H-l5 and l6-20, respectively. These ledges are punched out from the central wall of the upright channel member. Each of these ledges forms a carrier for removably supporting the associated end of the corresponding panel background member. Associated with each pair of carrier ledges are stop members such as indicated at 4l/42, 43/44, 45/46 which are likewise punched out from the front Wall of the channel upright and project perpendicularly therefrom. The inner edges of these stop members are in substantially vertical alignment with the outer edges of the associated ledges 38, 39 and 40, respectively.

The uprights may be formed differently, e. g., as shown in Fig. 7, or they may be made from fiat'strip material with the carrier ledges and with the stop members punched out and pressed out forwardly, as described. If flat striplike uprights are used, they may be provided with tubular bushings at predetermined points, for accommodating bolts or screws which secure them to the supporting structure, wall or the like. Each of the bushings may somewhat project from the plane of the upright in order to provide slight spacing from the supporting structure. Spacer washers may be used, if desired.

Each of the panel-like background members may be made of suitable sheet material and may have a desired surface finish; for example, the surface may be enamelled.

The background panel members H and 16 on top of the structure are alike, each forming a body portion extending in a plane substantially in parallel with the plane of the supporting sur face, e. g. the surface of a wall; The material of the body portion is bent forwardly on top to form a forwardly projecting ledge 56. At the bottom, each of these top panel members is bent anguiarly rearwardly, as indicated at 5!, to form a downwardly and rearwardly depending skirt so as to provide for draina'geof moisture. At the opposite ends each panel member is bent rearwardly to form the flanges 52 and 53, respectively, and each of these flanges is a'ngularly notched, as indicated at 54/55 and 56/51, respectively.

All of the intermediate background panel members H44 and I1-l9, respectively, are alike, and the description of two of them, namely, the panel members l2 and I1, will suffice for all. Each forms again a body portion which extends substantially in parallel with the surface of the supporting structure. The top of the body portion is bent angularly forwardly to form the carrier ledge 22 (panel member 12) which is, in the assembled position, in alignment with the corresponding carrier ledge 26 of the background panel member l1. At the bottom each such background member is bent angularly rearwardly, as indicated in Fig. 4 at 60 and 6|, and the opposite ends of each panel member are bent rearwardly to form the flanges 62, 63 each of which is slotted as indicated at 64/65 and 66/61, respectively.

The background panel members I5 and 26 disposed at the bottom of the sign are alike, each forming an angularly forwardly projecting top carrier ledge, as indicated in Fig. 4 at 25 and 29, with the bottom portion bent forwardly perpendicular to the plane of the body portions, as indicated at 12 and 13. The opposite ends of each of these background members are again bent rearwardly to form flanges 14 and 15, and each of these flanges is again angularly slotted, as indicated at 16/11 and 16/ 19, respectively.

After the channel uprights 35, 36, 31 are put in place on the supporting structure, wall or the like, the various background panel members are removably secured thereto simply by attaching these members with their hooklike means, i. e., with their slotted end flanges in engagement with the respective pairs of carrier ledges such as 38, 36 and 46. The background panels I l and l 6 are thus put in position on top of the structure. The panel II with its slots 54, 55 in the flange 52 at its left end will engage the carrier ledges formed by the pair of wings 38 on top of the upright 35, and the notches 56/51 in its end flange 53 will similarly engage the carrier ledges 36 of the central or intermediate upright 36. The top background panel 16 is similarly put in place with the notches 54/55 in its rearwardly directed flange 52 at its left end hooked over the carrier ledges 36 of the central or intermediate upright 36, and the notches 56/51 at its right end flange 53 similarly hooked over the carrier ledges 36 of the terminal upright 31 at the right end of the sign.

Each of the downwardly successive panel background members is secured similarly with the notches in the flanges at its opposite ends hooked over the corresponding pairs of carrier ledges on the uprights.

The inner ends of the panel members abut, in the assumed embodiment, in the center of the structure centrally of the central or intermediate upright 36 along the line 2| indicated in Figs. 1 and 2. The pairs of stop ears such as 41/42, 43/44 and 45/46 have no particular function if the upright such as 36 is used in the center of the sign structure or at another intermediate or dividing point. They serve the purpose of preventing the various background panels from slipping off laterally outwardly of the terminal channel members at the opposite ends of the sign. Thus, in the assembled structure, the outer ear 4| at the top of the left end terminal upright 35 prevents slipping on of the panel member I I, thus keeping this panel member in proper position with its right end substantially centrally of the intermediate upright 36; and the outer ear 42 on top of the right hand terminal upright 31 similarly prevents slipping off of the background panel l6, thus keeping this panel in proper position with its inner end in alignment with and abutting the inner end of the background panel H. The outer ears on each of the terminal uprights 35 and 31 associated with the respective downwardly successive pairs of carrier ledges, such as the stop ears 4344 and 4546, keep the corresponding horizontally aligned pairs of panel members similarly in position with their inner ends in alignment and abutment centrally of the intermediate upright 36, preventing the slipping off of these panel members from the structure, thus facilitating assembly of the parts and maintaining the parts in assembled position.

The forwardly protruding ledges 56 extending from the background panel members if and I6 on top ofthe structure and the similarly for wardly protruding ledges I2, 13 carried by the bottom panel members I5 and 29, respectively, havelthe purpose of aligning with the interior parts of the sign and angular border frame or finishing strip having the portions 3 I, 32 and .33, 34. This border frame maybe of a simple angular structure, as particularlyshown in Fig. 6,-and its respective portions are simply slipped over theledges 50'and 'I2-'I3 formed on top and at the bottom, respectively, by the top and bottom background panels II-I6 and I540, respectively. The end members 33, 34 of the border frame are similarly in alignment with the rearwardly directed outerside walls of the .terminal channel uprights 35 and 31, respectively. These outer side walls thus form aligning, guiding and mountingmeans for the end members of the border frame in the same manner as the ledges 50 and 12-13 of the top and bottom panels form a lining,

guiding and mounting means for the top and 'bottommembers of the border frame.

If desired, forwardly protruding ears may be punched out from the outside flanges of the channel uprights to form means for guiding the 1 end walls 33, 34 of the border frame into position and for aligning and securing the border frame on the uprights.

In case the uprights are made of fiat sheet stock, they may be provided at their edges with ears similar to the ones shown at 4 I/ 42, etc., and with similar ears at the ends, for guiding the border frame into position, for aligning it and for securing it thereon.

Thebackground has been shown in two horizontally aligned sections, each section comprising a definite number of vertically successive horizontally extending backgroimd panels. It is understood that this has been done only for the purpose of giving an example, as it is entirely possible to make the uprights longer, as long as necessary and practicable, to provide signs of greater height, and similarly toprovide more than three uprights, two at the ends of the sign functioning as terminal uprights, as described in connection with'the uprights 35 and 31, and severa1'intermediate uprights such as 36, each in back of a dividing line such as 2 I where the corresponding intermediate strip-like background panels abut. The background panels may be of standard size, that is, each of similar height and length, and in that case the intermediate uprights will be mounted along center lines which are similarly spaced. The spacingof the terminal uprights at the opposite ends of the structure with respect to the corresponding'nearest inter-ior intermediate uprights is slightly difierent, these spaces being less, in order to fix the panel members'at the opposite ends of the structure in position, held by the stop ears such as M and 42, etc., projecting from the terminal uprights as described.

The modification shown in Fig.5 provides uprights such as 80. From the center wall of each such uprights are punched out and rearwardly bent'the guide wings such as 8I, 82 and 83, thus forming carrier ledges such as 84, 85 and 85. A cutout 81 is formed on top of the upright to provide the carrier ledge 88. There are thus two carrier ledges 88-84 for the background panel 90 on top of the structure and pairs of carrier ledgessuch as 85/86 for each of the downwardly successive intermediate background panels, one of which is indicated at 9|. The top panel 90 hasa forwardly projecting ledge Siandhooklike brackets :93, 94- for mounting engagement with the carrier ledges 88 and 84 on the upright 80. The intermediate background panel 9! is bent angularly forwardly at its top, as indicated at 95, and is provided with similar hooklike brackets 96, 9'! for engagement with the carrier ledges 85, 85. The remaining intermediate background panels are constructed just like the ones shown at 9!. The bottom background panel (not shown) is constructed similar to the one shown at I5 and 2B in connection with the previously described structure, except that there is no flange such as 74-45 (see Fig. 4), but hooklike brackets at each end of the background panel such as 93/94 and 95/91, respectively, shown in connection with the background panels 90 and 9|.

The assembly and operation of the structure shown inFig. 5 is similar to the one already discussed. The rearwardly directed wings such as SI, 82. 83 inthe uprights have an angularly forwardlytilting portion, as shown in Fig. 5, which functions as a guide for the insertion of the corresponding hooklike bracket such as 4 and 96/91, on the respective background panel, and also holds its associated bracket in place after in-. sertion, thus securingthe corresponding panel in position. The coaction is wedgelike just as in the case of the carrier ledges with the slotted flanges at the ends of the background panels of the previously described structure. The assembly of the sign ,is thus facilitated and secured. Separate stop ears such as the ears II/42, 43/44, 45/ 45 shown on the uprights oi": the previous embodiment are not required in the structure of Fig. 5, because the inner edges of the cutouts forming the carrier-ledges 83/84 and 85/86 operate as. stop and aligning means for the end panels when the uprights are used as terminal uprights.

The embodiment shown in Fig. '7 provides simplified channel uprights each forming a mounting portion I40, a forwardly projecting side wall I4I, a front wall I42, and a rearwardly extending flangelike partial side wall I43. On top of the front wall I42 is provided a cutout forming the carrier ledge I44, corresponding to the top carrier ledges 38 and. 88, respectively, of the pre viously described structures. Underneath this cutout is disposed the angular aperture I45 forming the carrier ledge I46 which corresponds to the carrier ledges 38 and 84, respectively, of the previous embodiments. This pair of carrier ledges (I44I4B is provided for supporting the hooklike members I41, I48 extending rearwardly from the top background panel I49. Each hooklike member carries a nipple-like extension, as indicated at I56, I5I, respectively, for locking the corresponding end of the background panel I43 in engagement with the upright to prevent chattering, e. ,g., responsive to wind pressure on the panel.

The top panel also carries a forwardly,downwardly and inwardly disposed flange I52 which may be employed to form parts of-the frame or border on top of the sign. This flange takes the place of the flanges 50 and 92, respectively-of the top panels II and 96 of the structures described before. It will be understood of course that the flanges 50 and 92 of the previous structures may take the form, of the flange I52 shown in Fig. 7.

At the bottom, the top panel I49 carries a rearwardly directed drain skirt I53 correspond ing to similar skirts in the embodiments described before. 7

p The other lefthand end of thetop panel I 49" is formed just like the right hand end shown in Fig. 7.

The intermediate background panels (not shown in Fig. 7) are alike. Each is structurally similar to the intermediate panels of the previously described sign structure, each forming a forwardly tilted carrier ledge for supporting the various symbols for display, and a downwardly and rearwardly extending drain skirt, as described. The mounting means at each end of each intermediate panel corresponds to the hooklike mounting means I41, I48 described in connection with the top panel I49. Pairs of cutouts or apertures such as I45 are of course provided in each of the uprights for receiving the hooklike mountings of the intermediate panels. Each hooklike mounting member is provided with a nipple, as indicated at I50, I I, to obtain positive wedgelike locking engagement of the corresponding panel with the upright at either end thereof.

The bottom panel I54 corresponds structurally generally to the previously described bottom panels except for the bottom flange I55 which may be used, just like the top flange I52 of the top panel, to form part of the frame, and hooklike mounting means I58, I51 at each end, each having a locking nipple such as I58, I59 for supporting and locking coaction with the carrier ledges I50, IGI of a pair of cutouts I62, I63, re-

spectively. Numeral I54 indicates the angularly s;

forwardly directed member forming the carrier ledge for supporting the symbols for display as before.

Several uprights such as the one shown in Fig. 7 may be suitably mounted on a desired structure, wall or the like, by screws, bolts or nails or the like, which are driven through holes such as I55 provided in the wall I48 of each upright. It should be observed that such screws, bolts, etc. are accessible through the corresponding cutouts such as I45, I62, I63 in the front wall of the upright, facilitating the mounting thereof.

Each of the cutouts such as I45, I62, Hi3 has a recessed upper portion, as indicated at M511. I52a, I63a, respectively;

The mounting of the various background panels is accomplished by taking each panel and inserting its pairs of hooklike mounting members, at its opposite ends, into the right hand ends or sides of the corresponding pairs of c touts in two horizontally successive uprights. The panel is then slightly dropped and moved to the left until the two hookl-ike members at its left end are in engagement with the left side edge of the cutouts in the corresponding left hand terminal upright (as would be the case with the panel corresponding to panel II in Figs. 1-4 and 6) or in alignment with and abutting the right end of the adjacent panel on the left (as would be the case with a panel corresponding to the top panel IS in Figs. 1-4 and '6). -After a panel is put in position in this manner, it is moved downwardly to obtain locking engagement of its hooklike mounting members with the carrier ledges of the cutouts in the corresponding uprights. The panels are then endwise in alignment. All panels are put in position in this manner. The hooklike mounting members of the various panels are accommodated within the left stepped portions of the corresponding cutouts in the uprights. Each panel is positively locked in place at each end thereof.

The flanges I 52 of the top panels are in alignment, forming the top portion of the frame. The flanges I55 of the bottom panels are similarly in alignment, forming the bottom portion of the frame. The various forwardly tilting ledges formed by the intermediate panels and by the bottom panel, respectively, are likewise aligned and ready to receive the symbols for display, as already discussed. Suitable border strips may be secured to the sides of the terminal upright at the ends of the sign to complete the frame. If desired, a finishing strip may be put on the aligned top and bottom frame flanges formed by the flange portions I52 and I55 of the top and bottom panels.

Drain holes, as indicated at I10 and III, may be provided in the frame or flange portions I52 and I55 of the top and bottom panels I49 and I55.

It will be seen from the foregoing explanations that a sign made in accordance with the example shown in Fig. 7 comprises again the elements described in connection with the previous embodiments, the coaction between such elements likewise being similar. The advantages resulting from the structure shown in Fig. 7 reside in utmost structural simplicity, more positive locking action of the panels in engagement with the uprights, and use, if desired, of the top and bottom flanges of the panels to form parts of the frame with or without finishing strips.

The modification shown in Fig. 8 corresponds substantially to the structure shown in Figs. 1-4 and 6 and in Fig. 5, except that it is adapted to accommodate letters or symbols of the so-called lug type in which each symbol is provided'with one or more lugs at the top and at the bottom, which extend therefrom, for mounting symbols in channel-like adapter members.

Referring now to Fig. 8: Numerals I00, IIII and IE3 indicate letters or symbols of the lug type. The lugs of the symbol I00 are indicated at ltd/I65. Similar lugs Hit/Ill! and NIB/I09 are carried by the remaining letters or symbols IIlI and I93, respectively.

The panel-like background member II 0 maybe formed just like the panel background member ll of the previous structure, having a forwardly projecting ledge III and an 'angularly rearwardly directed drain skirt I I2. Each of the intermediate background panels H3, H4, H5 is formed generally like the corresponding previously described intermediate panel members, each having a rearwardly directed bottom drain skirt, as indicated at Ht, Ill and H8, respectively, and each having an angularly forwardly tilting top portion, as indicated at H9, I25 and I2I, respectively. The bottom background panel I22 has on top an angularly forwardly tilting ledge portion I23 and at the bottom a forwardly directed ledge I24. Secured to each of the forwardly tilting top portions of the intermediate and bottom background panels is a cross-sectionally H-shaped double channel member, as indicated at I25, I26, I21 and I28, respectively. The lugs of the various letters or symbols of the lug type are inserted into the channels which face each other; that is, the lugs of the letter or symbol I08 are secured in the channels carried by the channel members I25 and I26, respectively; the lugs of the letter or symbol I GI are removably inserted in the channels formed by the channel members I 26 and I21, respectively; and the lugs of the lowermost lug type letter or symbol are similarly inserted in the channels of the channel members i2? and I28, respectively.

The opposite ends of each of the background panel members H0, H3, H4, -'I I5 and I22, respec-' tively, may again be bent rearwardly to form flanges, and each such flange may be provided with inclined notches for removably mounting the various panels on carrier ledges such as 38; 39, 40 in the channel uprights shown in Figs. 1-4 and 6.

A finishing frame or border may again be provided in the structure shown in Fig, 8, in the same manner as in the previously described structures.

The modification shown in Fig. 9 contemplates background panel members just like the ones shown in Figs. 1-4 and 6, one being shown in section and indicated by numeral I30, carrying on top an angularly forwardly projecting carrier ledge 13! and at the bottom an angularly rearwardly directed drain skirt I32. A slotted mounting flange I33 is provided at each end of the panel for mounting on carrier ledges of uprights in the manner already described. 'The carrier ledge |3I may thus be used as before, for supporting a symbol of the slotted flange type. Adapter strips such as shown at I34 may be removably secured to the ledges 13! of the various background panels, by suitable mean-s such as clips or screws, for alternatively supporting symbols of the lug type, as shown in Fig. 7. The corresponding sign may thus be quickly adapted for use with either type of symbols.

It has been assumed that there are two hooklike or equivalent mounting member at each end of each background panel member, for coaction with corresponding pairs of mounting or carrier ledges formed on the uprights. The number of such mounting members may of course be more or less, as may be desired.

The use of the cross-sectionally H-shaped channels or adapter members has been described with reference to the embodiment shown in Figs. 1-4 and 6 only for the sake of convenience. It is clear that such channels or adapters may be similarly used with the structure illustratedin Fig. '7.

Changes may be made within the scope and V spirit of the accompanying claims inwhich is defined what is considered new and desired to have protected by Letters Patent of the United States.

A changeable si n of the class described comprising a pair of horizontally spaced vertically extending uprights. each u right being cross-sectionally generally U-shaped to form with one leg thereof a rear wall for attachment to a supporting structure and with the other leg thereof a front wall spaced from said rear wall. longitudinally ste ped cutouts formed in said front wall, each cutout having a relatively narrow top section and a wider bottom section downwardly extending therefrom, the bottom edge of the bottom section of each cutout forming a mounting ledge, a plurality of background panels, each panel having rearwardly directed hook-like means for insertion into one of said cutouts and for mounting engagement with the corresponding mounting ledge thereof, said hooklike means being insertablev into and removable from, its associated stepped cutout only along the entire length of such cutout including the narrow and the wider section thereof and being in mounted position disposed in said wider portion of said cutout in relatively fixed relation therewith, and angularly forwardly directed fiangelike display means carried by each background panel.

12. A changeable sign of the class described comprising a plurality of structurally substantially identical generally cross-sectionally rectangular generally vertically disposed horizontally spaced channel-shaped upright mounting members, each mounting member having a rear wall for attachment to suitable supporting means and a front wail spaced from said rear wall, a longitudinally extending cutout formed in the front wall of each upright mounting member, each cutout having at one end thereof a stepped configuration to form an elongated slotlike opening having a relatively short portion adjacent a relatively long portion, the other end of each cutout forming a mounting ledge, a background panel forming a display surface for disposal between said upright mounting members and haying a hooklike member rearwardly extending therefrom at each end thereof for removable attachment to the mounting ledge formed by the cutouts in the correspondingly disposed upright mounting members, the length of each hooklike member corresponding substantially to the length of the relatively long portion of the cutout in its associated upright mounting member, whereby said background panel can be removably mounted on said uprights by insertion of its hooklike members through the relatively long portions of the cutouts therein and locked against inadvertent displacement with respect to said upright by disposal thereof sideways relative to said uprights to position said hooklike members within the relatively short portions of said cutouts.

13. A changeable display sign of the class described comprising means forming a plurality of horizontally extending vertically successive pairs of carrier ledges, each pair of ledges for removably supporting symbols each of which consists of a symbol body having rearwardly extending flanges and notches in said flanges for engagement with the corresponding pair of carrier ledges, and adapter means for removable attachment to each pair of carrier ledges to form thereon horizontally extending vertically directed channels for removably supporting symbols each of which consists of a symbol body and luglike extensions projecting therefrom for insertion into said channels, said luglike extensions projecting from the corresponding symbol body in a plane which generally parallels the plane of the face thereof.

14. For use in a changeable display sign having at least two pairs of horizontally extending vertically spaced barlike members, each pair forming two carrier ledges for supporting letters to be displayed thereon each of which has rearwardly directed flanges with notches formed therein for hooklike engagement with said carrier ledges, an adapter for removable attachment to each pair of said carrier ledges, said adapter consisting of a holder comprising a horizontally extending panel member, flanges rearwardly extending from said panel member which are slotted for hooklike engagement with said carrier ledges, and a cross-sectional H-shaped strip on said panel member extending along one edge thereof, said cross-sectionally H-shaped strip forming in mounted position of said panel memher on said carrier ledges vertically directed horizontally extending channels for removably supporting in front of said panel member different letters each comprising a symbol body and a luglike extension projecting therefrom generally in parallel with the face thereof for insertion into a channel formed by said cross-sectionally H- shaped strip.
