Referring to Figures 1 to 5 the device illustrated thereby includes a vertically disposed one-piece body part; 20, whichv is stamped from any suitable metallic material and is so shown. It is to be understood that body part 2B may be molded from` any suitable plastic material if desired. The said body part is open at its real' and it includes a front wall 2l, a pair of side walls 22, 23, a top wall 24 and a bottom wall 25. The walls 2|, 22, 23 and 24 merge into each other. The wall 25a't its front merges into the lower end of and is` disposed at a downward vinclination with respect to the wall 2l. The rear end of wall 25 terminates into a vertically disposed depending extension 26, which at its lower end merges into a forwardly directed ange 2l. The walls 22, 23 at their rear merge into a pair of oppositely disposed lateral extensions 23, 29 respectively terminating into forwardly extending anges 30, 3| respectively. vThe top wall 24 terminates at its rear into a vertically disposed extension 32 which merges into a forwardly directed flange 33.

The extensions 28, 32 align. The flanges 2l, 33 align. The extensions 28, '29 align, and the flanges 30, 3l align. 'The extensions 28, 29 are formed with openings 34, 35 for the passage of holdfast means to anchor body part 20 to a support, by way of example in proximity to or upon the front door of .a building or at any other desired point. The flanges 3|), 3l are formed with Y V threaded Vopenings 36 for a purpose to be referred to. The extension 32 is provided with an opening 31 for the passage of holdfast means to anchor such extension against the aforesaid support. The bottom wall 25 is formed with an enlarged opening 40 for a purpose to be referred to and also with a set of spaced slots 39 at its point of jointure with the bottom of wall 2|. The top wall 24 is provided with a set of spaced slots 39 at its point of jointure with the upper end of the wall 2|. be presently referred to. The walls 22, 23 are slitted, as at 4|, and the material freed by said slits is bent forwardly to beyond the. sides of the front wall 2| to provide holding tongues 42 for a purpose to be referred to. The slits 4| are at the points of jointure of the side walls with the sides of the front wall. The forward face of the latter is formed with an opaque coating 42.

Encompassing the body part 2|) is a cover element 43 of frame-like form consisting of a front portion 44 formed with an opening 45 having its edge provided with an endless rearwardly directed spacing bead or rib 46, side portions 41, 48, a top portion 49 and a bottom' portion 50. Each of the side, top and bottom portions consists of an outwardly directed rearwardly extending curved forward part merging into a straight rearwardly directed back part' 52. The element 43 is of one-piece and may be stamped from metallic material or molded from any suitable plastic, but it is shown by way of example as stamped from a single length of sheet metal. The manner in which the element 43 is arranged relative to body part 28 will be hereinafter more specifically referred to.

rThe rear parts 52 of the said side portions 41, 48 are formed with openings 53 and such parts are positioned against the outer faces of the iianges 38, 3|, which are connected with the said side walls 22, 23. The openings 53 register with the openings 36. The rear part 52 of the said top portion 48 is positioned against the outer face of the flange 33, which is connectedy with the top wall 24. The rearpart 52 of the said bottom portion 5i] is positioned aganst the lower face of the flange 21 connected with the said bottom Wall 25. Correlating with the registering openings 36, 53 are attaching means 54 for detachably securing the element 43 to the body part 28. The cover element, if constructed of sheet metal, will be of a size to be snapped about the body part 26 and to frictionally engage the anges aforesaid.

The lower part of the said front portion 44, the lower part of the said side portions 41, 48, the said bottom portion 50, the said inclined bottom wall 25, the said extension 26 and flange 21 are so correlated to form a chamber 55 for an electric lamp 56, which is extended into such chamber through an opening 51 formed in the wall 25. The latter is provided with an apertured lug 58 carrying a holding or suspension means 59 for and which engages the lamp 56. The said bottomwall 25 forms the top wall of the chamber 55. The lower part of the said front portion 44 and the part 5| of the said bottom portion 50 of the element 43 form the front wall of the chamber 55. The top wall of chamber 55 is spaced rearwardly from the upper end of the front wall. of such chamber to provide a light emitting passage 66. The chamber 55 is closed at its front, sides, bottom and back. The walls of the chamber 55 are formed throughout with a coating 68a constituting a reflecting surface and by Way of example said coating may be white paint or white enamel.'

The purpose of the slots 39, 40 will The device includes a display carrying means for any suitable indicia. The latter is shown by way of example as designating a house number. The said means will be formed of a plurality ci components, and by way of example is illustrated as consisting of four components 6|, 62, 63 and 64 arranged at the rear of the front portion 44 of element 43 and at the front of the wall 2i of body part 20 between the tongues 42 extended from the side walls 22, 23 of body part 26. In the example of the invention as shown each cornponent consists of a rectangular transparent panel 65 preferably formed of glass provided on its rear face with a digit or an ought. Preferably the digits and oughts will be white and are painted on the rear faces of the panels. As shown, the panel 65 of the component 6| has a digit 66 on its rear face which indicates one; the panel 65 of the component 62 has a digit 61 on its rear face, which indicates two the panel 65 of component 63 has an ought 63 on its rear face; and the panel 65 of component 64 has a digit 69 cn its rear face which indicates fourf The example as aforesaid will indicate the house number as 1204. Preferably the panels of the componentsV will be of the desired size and also correspond in size. The panel of each component is adapted to be illuminated from an edge thereof and that edge of the component opposite the edge which the light enters is provided with a White coating. In the example of the invention as shown the said coating is indicated at 63a and it is throughout the top edge of the panel.

There is correlated with each component of the display carrying means a combined supporting and coupling member 16 therefor. These members are of like form and each consists of a rod of circular cross section formed of a straight intermediate portion 1|, an upper end portion 12 constituting a coupler and a lower end portion 13 providing a support. The end portions 12, 13 are angularly disposed with respect to and extend forwardly from the ends of the intermediate portion 1|. The upper end portion 12 is of hook form, and the lower end portion 13 straight.

The members 16 are removably mounted in and supported from the body part 26 and when mounted relative to the latter each couples a component of the display carrying means to body part 20 and also supports the component. The latter when coupled to and supported in relation to body part 20 is arranged in juxtaposition to the forward face of the front wall 2| of the said body part.

The intermediate portions 1i of the members 10 are arranged rearwardly of and in proximity to the rear face of the front wall 2| of body part 2D; the upper end portions 12 of the members 16 extend through the slots 38, pass over the upper end of wall 2| and overlap the top edges of the said components; and the lower end portions 13 of the members 16 extend through the slots 4i! pass Linder the lower end of wall 2| and bear against the bottom edges of the said components. This arrangement provides for not only supporting the said components relative to body part 28, but also couples the components to said body part. The members 1i) are disposed centrally with respect to the said components and arranged in parallel spaced relation. When the components are supported and coupled relative to the body part 2|) the bead 45 on the front portion 44 of the element 43 bears against the front faces of and acts as a retaining means for holding the components against the wall 2| of body part 20.

The bead 46 at its top is arranged below the outer termini of the end portions 1.2 of the members 19. The bead 46 at its bottom is arranged above the outer termini of the end portions 13 of the members 19. The end portions 12 are of greater length than the end portions 13.

The leading-in-wires for the lamp 56 are indicated at 14.

The manner of installing the components of the display means relative to the body part 20, cover element 43 and lamp 56 provides for the illumination of the said components from their bottom edges, as such edges are positioned in the opening 69 formed in the top of the lamp chamber 55. The opposing of an opaque background by the white indicia on the rear faces of the transparent panels will provide for such indicia to be readily visible by day and also when the components are illuminated at night.

With reference to Figures 6 and '1 the construction shown thereby will correspond to that shown by Figures 1 to 5, with this exception that the combined supporting and coupling member indicated at 15 will be flat and rectangular in transverse cross section in lieu of its being rounded and of circular cross section. The intermediate part, upper end hook-shaped coupling part and lower end fla-t supporting part of member 15 are indicated at 15, 11 and 18 respectively. The end portion 11 is of greater length than the end portion 18. l

The modied form illustrated by Figures 8 and 9 relates solely to the body part 19 of the device. The body part 19 is so formed as to have inherent parts thereof constitute means for coupling thereto and supporting therefrom the components of the display carrying means instead of using the members 19 or 15. The body part 19 will include front, top, bottom and side walls, but only one of the side walls is shown and indicated at 89. The front, top and bottom walls of body part 19 are indicated at 8|, 82, 83 respectively. The front face of wall 8| will have an opaque coating the same as the front wall 2| of body part 29. The top wall 82 is formed with a series of spaced slits 84, only one shown, and the material freedby each slit is bent forwardly to extend beyond the wall 8| to provide a coupler 85 for a display component. The coupler 85 is of hook-like form and overlaps the top of display components (Figures 8 and 9) for coupling the latter to body part 19. The bottom wall 83 is formed with a series of spaced slits 86, only one shown, and the material freed by each slit 86 is bent forwardly to extend beyond the front wall 8| to form a at support 81 for the bottom edge of a display component (Figures 8 and 9). Otherwise than that as stated the modified construction shown by Figures 8 and 9 will be the same as that illustrated by Figures 1 to 5 or 6 and '1.

The form of the device shown by Figures 10 and l1 will be the same as that shown by Figures l to with the addition of a latching flange 88, which extends inwardly at right angles to the rear part 52 of one of the side portions of the cover element 63. The flange 88 is spaced from the upper and lower ends of such portion and it is for snapping against the rear face of the extension 28 on a side wall of the body part of the device. A further difference between the form shown by Figures and 11 and the form illustrated by Figures 1 to 5 resides is not providing that part 52 formed with the flange 88 with an opening 36 or securing such part 52 by a holdfast means 54 to the flange 39. Otherwise than that as stated the form shown by Figures 10 and 11 will be the same as that illustrated by Figures 1 to 5.

With reference to Figure 12, the modified form shown thereby includes a body part 89 and a cover element 99. The body part 89 is similar to body part 29 with the exception that the anges 9|, 92 connected with the side walls 93, 94 respectively of the body part 89 are not formed with openings 35 as the flanges 39, 3| of the side walls 22, 23, and that the flange 9| is formed with a detent having its concave side outermost. The cover element 99 is similarvto cover element 43 with the exception that the rear part 96 of the side portion 91 of element 99 is not apertured as is the side portion 41 of element 43 and such part 95 is formed with a detent 98 having its convex side innermost for correlation with the detent 95 for latching element 99 to body part 89 by a snapping action.- A further difference between the element 99 and the element 43 resides in the providing oi the rear part 99 of side portion |99 of element 99 with an inwardly extending flange |9| for abutting the rear face of the extension |9|2- on the side wall 94. Otherwise than that as stated the form shown by Figure 12 is to conform to the construction of the device shown by Figures 1 to 5.v

With reference to Figures 13 and'l there is illustrated still another modified form of body part which is molded from plastic material. Such body part is indicated at |92 and includes flanged top, side, front and bottom Walls of the same form as the walls of body part 29,' with this exception that top wall |93 and bottom wall |94 of body part |92 are not slitted or formed with openings and that the side walls |95 of body part |92 merge at their lower ends into the bottom wall |94. A further difference between body part |92 and body part 29 resides in forming the upper face of the top wall |93 with integral spaced parallel pairs of spaced oppositely disposed inverted L-shaped members |96, which are flush at their forward ends with the front face of the front wall |91 of body part |92. Only one pair of the members |96 is shown and each pair of said members constitutes a holder for a resilient coupler |98 of hook-like form for a display component |989, The couplers |99 will be of like form and each includes a shank having having a part |99 bearing against the inner face of the top of the holder and a bow-shaped part ||9 bearing against the upper face of said top wall |93. rihe shank of the coupler coacts with a pair of members |99 and the top wall |93 for latching the coupler |99 to body part |92. Another diierence between body part |92 and body part 29 resides in the providing of the outer faces of the side walls |95 with integral forwardly directed lugs only one shown, which extend beyond the front wall |91 and function for the same purpose as the tongues 42 of body part 29. A further difference between the body part |92 and the body part 29 resides in the providing of the bottom of the front wall |91 with spaced parallel integral forwardly directed lugs I2, only one shown. The lugs ||2 align with the couplers |98 and each constitutes a support for the bottom edge of a display component. Otherwise than as stated the construction of the body part |92 will conform to body part 29.

With reference to Figures 15 and 16, a modification of the device is shown and it is formed so as to permit of it being attached at its top to a suspension |l3. The device as illustrated by or plastic material, and it includes a body part ||4 and a cover element ||5. The body part ||4 will be substantially of a form corresponding to that of body part ZIJ' with the exception that the top wall IIS thereof is formed with an opening I I'I for the passage of the leading-in-wires I8 to the lamp arranged in the lamp chamber. The lamp and its chamber are not shown in Figures 15 and 16. A further difference between body part ||4 and body part 20 is the forming of the iiange IIS, which is connected with the top wall IIB, with a cutout |20 for the passage of the wires II8.

The cover element I I 5 shown by Figures 15 and 15 is constructed similar to the cover element 43, with the following differences. That the rear part |2I of the top portion |22 of element ||5 is formed with an opening |23 for the passage of the wires I I8; that the upper face of the said part |2| is formed with a concave recess |24 rearwardly of the opening |23; and that the said top portion |22 has integral therewith a vertically disposed apertured lug |25 to which the suspension ||3 is attached. The coupling and supporting means for a display component employed in the form of the device shown by Figures 15 and 16 may be similar to that of Figures 1 to 6 or that shown by Figures 13 and 14. The device as illustrated by Figures 15 and 16 includes a rimlike closure |26 for the back of body part IIll and element I I5. The closure |26 has its rim portion I 21 encompassing the rear of the element II5. The said portion |21 includes a lug |23 for snapping in the recess |24 whereby the closure |26 will be latched to element H5. Otherwise than that as stated the form illustrated by Figures l5 and 16` will .correspond in construction to the form shown by Figures 1 to 5.

With reference to Figure 17 there is shown a i modied form of closure |29 for the back of the body part |30 and closure element |3| of the device. The element |3| will correspond in structural arrangement to the element 43. The body part I 30 will be similar to the body part 2U with this exception that the extension |32 on the top wall |33 is formed with one or more threaded openings |34, only one shown. The closure |29 is in the form of a flat plate |35 which abuis against the back of body part |33 and element 53, and it is detachably secured in such position by the holdfast means |36 extending through the plate |35 and engaging in an opening |34. When the device shown by Figure 17 is set up the openings 34, 35 (Figure 2) preferably will be omitted.

It is to be understood that the front face of the front wall of any one of the body parts will be provided with an opaque coating and that each display component will have an edge formed with a white coating as referred to.

The components of the display means are to be arranged against the opaque front face of the front wall of a body part. Each component is positioned separately, after which it is coupled and supported relative to and in juxtaposition to such wall by a member IG or l5, or by a coupler |03 and a lug I I2. The component or panel when positioned as aforesaid has its lower portion eX- tended into the opening 60 to a point below the lower portion of the bead 45. After the desired number of display components or panels are arranged in the manner as aforesaid the body part of the device is encompassed by a cover element and the latter is then latched or secured to the Figures l5 andV 16 may be formed from metallic` body part. When the cover element is secured to the body-part the display carrier means extends above the top portion of the bead 4B and also extends laterally from the side portions of the bead 4B. It will be stated that the indicia on the panels will be displayed through the opening i5 in the front portion 44 of a cover element. When the display carrier means is arranged in position the upper, lower and :side marginal portions of its front face will be overlapped by the front portion of the cover element, and when in such position the bead 46 will bear against such means and in connection with the coupling and supporting means hold said display carrying means in vertical position for displaying the indicia.

The panels of the display carrying means are arranged in sidewise abutting relation and are held in such position by the tongues 42 orl lugs The panels of the display carrying means may be readily removed after the cover element is removed or when the closure |23 is detached from the cover element and the latter removed from the body part of the device.

At night the display carrying means is illuminated from its bottom edge by the lamp 56. It is to be understood that the leading-in-wires are to be provided with a switch and also a plug for connection to an electrical output. It is thought unnecessary to show this arrangement as it is common.
