sun on REMOVABLE BUILDING rnon'r.

Application filed April 25, 1927. Serial No. 188,480.

My invention relates to a sub or removable building front, that can be applied to old or newbuildings.

The object of this sub or removable building front, is to provide a front that can be removed in whole or in section. A front that can be provided with different designs, names, trade-marks, symbols, words or letters, or pictures formed by cutting through this removable front and inserting or placing difierent colored transparencies or a combination of colored transparencies over or in the cut through portion of the removbeautifying and illuminating the removable front with colors, or a combination of colors during the day by daylight, showing through regular windows, or windows provided for this purpose, in the removable front on the front or outer surface of the permanent building front, which has been turned into a reflector by covering its outer surface with white enamel, white paint, white tile, white porcelain, white brick or other methods of forming reflecting surfaces. When necessary, I use removable, adjustable or if desired permanent or fixed reflectors, independent of the permanent wall, or secured to or attached to it'or leaning against it or supported by any suitable means in front of it in such positions as will best illuminate the transparencies in the sub or removable building front during the day.

At night the reflectors, movable or stationary and apart or whole of the permanent front wall that has been turned into a reflector surfaced by white enamel or paint, or

otherwise, will be illuminated by a sufiicient number of electric lights to give the daylight appearance.

To provide'a sub or removable front that permits of colors, combination of colors, names, words, letters, or pictures etc to be changed at will and by this method or system, the cost of operating is reduced to about one-tenth of the cost of present methods of exterior lighting, decorating, beautifying or advertising, and as there are noxsockets, lamps or current carrying parts attached to sub or removable front, fire hazard is en tirely eliminated;

I attain these objects by the mechanism illustrated in the accompanying drawings.

Figure 1, is a vertical sectional view of the permanent front wall of a new or old building showing a section through the removable thin metal subfront 1, that is built infront of the premanent front wall 2 of the building with a sufiicient space in front of it to allow a workman to stand between them to make such changes as desired in the rear side of the removable thin metal subfront wall 1, in making up the words, symbols and such other advertising matter that is to be illuminated in different colors on the front side of the removable subfront, or removing lamps I and doing such-work as necessary on permanent walls.

Figure 2, is a perspective section view of a permanent front wall of a building and of my subfront wall showing a'door, window, advertising and decorative designs thereon.

Figure 3, is a plan view of a recess ortion of a permanent brick wall of a bui ding 2 and of my subfront wall 1, extending across the recess in the wall from-the outer edges of the recess, thus forming a space for workman to make and change the signs between the wall. 4 V Figure 4, is a plan view of a straight front *portion of a permanent brick wall, showing my thin metal building subfront built out from the straight face of the wall a sufficient distance .to allow a space between its inner side and the brick wall for workman to work Figure5, illustrates in vertical section a permanent brick wall containing a cellar portion and a'first floor portion and as illustrated my subfront as shown resting on a sidewalk constructed to sup ort its welght.

Figures 6 and 6 7 and l and 7 and 7, illustrate side and edge views of a colored lens, and they show three different ways of removably securing a lens to a fragmentary part of the subfront, and Fig. 7 illustrates an enlarged clamplng clip and screw construction I preferably use to or release the lens from the aperture in the subfront,and Figures 7 and 7, illustrate quickly, secure edge and side views of'the shape of the lens I I use in and over the apertures in my subfront.

Figures 8 and 9, illustrates in a plan view and a fragmentary front elevation of the construction of a column or pilaster arranged H with a man working space within it.

Fi 10 illustrates a, side view of V fletter N, formed of the lenses laced a short distance apartthroughout an on the lines of its shape.

Similar letters of reference refer to similar parts throughout the several views.

Referring to the drawings Figures 1 and 2, represent vertical sectional views showing my sub and removable and placed in new positions, consequently the design for illuminating in which they were first placed, has remained permanent. with no change possible.

My invention, however, provides a system by which different kinds ofv illuminating, beautifying and advertising can have any number of different colors and characters and arrangement that can be changed on the outside surface of my. sub or removable front, from day to dayor week to week or month to month or after a series of a few monthsdisplay of a certain design, advertising matter, colors, words, letters or pic-.

tures can be removed and a complete new front or section substituted for the one that has been in use.

Another new and very important feature of my invention is, that there are a great many old buildings to which my thin sheet iron changeable subbuilding front for ad- I vertisements can be applied, simply by placing the subfront a s ort space in front of the permanent front and attaching them in a substantial manner to the of the old buildings; and urthermore, an-

other valuable feature is this, that where a manufacturer or a builder ofany kind or character of a businessbuilding or other character of building for. amusement purposes or a theater or whether it is for a mannfacturin establishment, the front wall of the building, back of in sheet metal illuminated subfront can be uilt in front of it,

, and it can be very easily adapted to changable advertisin -'matter of the particular business for whlch the building is 'tobe constructed and used for.

My thin sheet metal advertising subfront 1, can be also decorated with architectural features, such as doors, columns or pilasters,

windows or any-other character of architectural embellishment that it is desired to gave to it';' but I have omitted from the illustration of'my invention some of these ermanent front features as it is obvious that they can be applied to the outside surface of my illuminated' advertising metal sub building front, and I have only shown in the drawings, plain-smooth sheet metal subfronts 1, with a door and windows, and my sheet metal subfronts are constructed preferably of 12 gauge sheet metal, but slightly thinner or afthicker metal can be used if desired. It is essential that it be thin enough to allow apertures A tobe quickly cut or drilled or punched through it to make up from time to time new designs; and I paint its inside surface and also its outside surface with white or enamel or aluminum or any other suitable paint B, as the paint usedon its inner surface increases the light between the subwall 1 and the permanent wall 2, and consequently increases the light that shines against the rear sides of different colored transparencies C, which ma be made of any suitable material, suchas g ass or crystal or other clear transparencies and colored material or materials.

Thenumeral 2, of the drawings, repre-' sents a section through the front brick wall of abuilding adapted for manufacturing purposes or for holding manufactured goods, and this wall is shown in section and it extends from its foundation members 3, of concrete or brick placed below the floor 4,-of the cellar portion 5 of the building up to the front story 6 as indicated by the fragment of the floor joist and floor 6-A, and the second floor 7, as indicated by the fragment of the floor joist and floor 7-A and this front brick ceiling. joist 8, of the roof story 8-A of m subfront 1, which is ositioned at only sue a short distance in fr brick wall 2 of the building, as will allow workmen to work between them by standing or sitting or kneeling upon suitable planks 9,

which are placed across and rest on top of either channel or I beams 9-A that are built at one of their ends into the brick wall 2, and project into the space between the brick wall and the inside surface of'the subfront 1, as

-is illustrated; but these Planks can be placed across and rest on top 0 anchor straps 10, as is illustrated at the upper floor and near the top of the building and which are bolted to the inside surface of the brick wall at one end and are releasably secured to the inside surface of the metal subfront at their opposite ends and the distance between the brick wall and the inside surface of the metal subfront, vary from about two and a-half to three feet depending largely upon the amount of changeable advertising matter that is contemplated doing inthe metal front and also on the character of illuminating light that is to be developed in the space and transmitted through transparencies that ont of the permanent vwall 2, of the building extends unto the if desired the sheet metal front may extend in one continuous integral sheet from the copper grounding plate 11, up to the full height of the building and as far above it as desired.

For convenience in handling and removing and erecting the metal advertising subfront of building, I divide it into sections of about the height of each. story which may be 10-12-14-16 or more feet as desired, and where a high metal subfront is to be built that requires several wide sheets of metal, their horizontal meeting edges'can be releasibly secured together, by theuseof either one of the three methods of joining the edges together shown in Figures D, E and F, or by any other suitable means. i

The thin sheets of metal out of which my sub building fronts are made can also be divided vertically as shown at 12 in Fig. 2, as this view represents a metal front that might be from twenty-five to. fifty or more feet in length, depending on whether the advertising metal front extends along the whole or only a part of the building to which it is to be applied, and where very long metal fronts are required that would have to be made up of a number of sheets of metal, secured together at their edges, and a doorway 18 can be formed in a long metal front if desired that would lead to 2.

ing the sunlight doorway 14 in the front brick wall of the building. Windows 15 are also placed in the front to light up the different colored transparencies ,C, of the advertisements and ornamentals made in the subfront by allowto show -through the windows against the white enamel paint B on the outer faces of the permanent front brick wall or from the light reflectors G, and from which the sunlight would be reflected against the rear side of the transparencies and through them out through the apertures on the subfront into the daylight.

My sub-front 1 can be set across the front space of recesses 16 formed in the front walls 2, of buildings between their side walls 17 as shown in Figure 3', and in that case the entrance doors through the brick wall can be placed in either one or both side walls, but where the sub-front 1, is built directly in front of the front brick wall 2, the entrance door into it, if one is required from thesidewalk, can be placed in one endof the sub-front 1, as shown in Figure 4.

In Figure 5, I illustrate a simpler and less expensive construction of my sub-front of the cellar or in case there is no cellar underneath a building, the ground 21 may be placed directly below the sidewalk as shown in dotted lines.

This construction differs from that shown in Figures 1 and 2, as in them, the lowest metal plate of the sub-front extends from the floor 4, of the cellar up close to or above the roof of the brick building as desired and consequentlythere is a clear space between the brick wall 1 and the sub-front 1, while in Figure 5, the subfront starts from the sidewalk.

My invention contemplates broadly any means for directing electrically generated light or daylight either from a light reflecting surface such as a white painted or enameled surface B, on the brick or on the surface of a separate surface of wood or metal G, as shown in Figures 1 and 4, that is separate from the brick wall and is placed in front of it, and the light from the several sources of da light and electric lamps H,in eacllli story of a building arranged substan- 'tia Figli re 1, and shines directly onto and against the inside white enameled or polished surface of the brick wall, or separate light reflecting surface and the bright light is reflected directly onto the inside white surface of the sub-front 1, and consequently on the rear sides of 'the different colored transparencies C, that are secured over. the holes A, that are formed in this submetal front to receive them.

I preferably lead the electric lamp current carrying wires 22 up along the rear side of the wall 2 in a steel conduit pipe 23, from which the currentcarrying wires are taken out of lateral metal pipes 24, that extends through the wall 2 and into and through fuse and switch boxes 25, that are built into the wall, or any other suitable Way, consistent with the rules of the National Board of Fire Underwriters covering electric wiring; and the wires extend through the pipes to electric lamps H, that light upthe light reflecting surfaces onto or between the two fronts 1 'and'2. .1

The current carrying wires that extend as on the diflerent floors shown in through the pipes are taken out of their is drawn out carefully and true to form on the inside surface of the metal subfront and then holes A, which may be of any shape dcs1red, such as square, hexagon, heptagon, octagon or any other form, but preferably round apertures are used, and the apertures are laid out at equal distances apart throughout the line of the shape of the design or advertising matter or whatever form and arrangement of its outlines may assume, and then the holes A, are cut through the thin metal and the rows of holes are ,cut on the outline of the letter, or letters or the orna mental design and the transparencies are removably secured centrally over each hole on the sub-front on its inside surface. The hole through the subfront is slightly smaller in diameter than, the diameter of the transparencies, consequently the transparencies overlap the edges of the holes while their bodies extend through the subfront and they are secured to the inside surface of the subfront by any suitable means.

I illustrate, however, three different ways of removably securing lenses of slightly different shapes to the sub-front in a manner that will permit them to be easily and quickly attached to or removed from over the apertures through the sub-front; thus in Figures 6 and 6-A, a lens C is shown over the aperture H, formed in a fragmentary piece-of the sub-front 1, and three metal clips J and screws K, are threaded in the metal front to swing on their clamping screws K, and they are made to overlap the edges of the lens C, and in Figures 7, and 7-A, double ended clips JJ, and their clamping screws 'KK, are shown clamping a lens in an aperture H, in a fragmentary piece of the subfront.

I preferably use, however, lenses that are provided with a thick flange at their rear side edges that overlap the apertures H. These flanged lenses project through and beyond the aperture in the metal subfront and they have substantially a semi-circular outline in their lens portion. This shaped lens is illustrated in Figure 7-B and 7 -G,

and they are removably secured to the inside surface of the, sub-front 1, by the same formof double ended clips J J as is used for the lens illustrated inFigures 7 and 7 -A. I

' preferably, employ, however, for securing this form of lens to the inside surface of the sheet metal front 1, a square shanked screw L, that projects and fits closely in a square hole formed through the sub-front to receive it, and it extends through the. sub

front from its outside surface and its head M, bears against the outside. surface of the shoulder and a check nut O, is threaded on it and is screwed down tight against the inside surface of the metal sub-front which clamps its head "tightly against the outside surface of the subfront, and the screw is prevented from turning in its square hole by means of its'square shank filling the same. yond the check nut through the double clips J J, and beyond it far enough to receive a nut on its outer end and the double clip extends over the square shouldered thick flanger portions of two adjacent lenses and they are securely but removably clamped a ainst the inside surface of the subfront by screwing the nut down on the stem to clamp the clip tightly against the outside surface of their flanges as shown in Fig. 7-B.

In Fig. 7-13 I illustrate an enlarged view of the square shouldered screw L, and its check nut and clamping clip and the flanges of two lenses between the clamping clip The stem portion N, extends be- 5 and the underside surface of the sub-front l and the nut on the end of the screw that and the reflected light strikes them centrally in their full diameter and their red or white or blue or green or scarlet or other colors are projected from them through the holes in the front plate into the atmosphere.

In Figures 8 and 9, Iillustrate my system of different colored transparencies applied to either plasters or columns. The manner of forming a colored sign or ornamental design in them is the same as on the inside surface of the sub-front, and the receive the light reflected from the ename ed white painted surface B, or the inside of the permanent wall 2, the same as the entire flat surfaces of the permanent wall and the sub-front.

My sub-front is adapted to extend along the whole or only a part of the whole length of a building and where it extends the whole length or a considerable part of the whole length of a building, it is'necessary to put windows in the subfront in alignment with windows in the permanent brick wall in order that the rooms in the building back of the permanent wall will be lighted by daylight, thus in Figures 4, 5 and 9, I illustrate windows LA, in the subfront and a window 2-'A in the permanent wall positioned light to enter into aroom to the light that 1s reflected against the rear sides ofthem opposite to'each other, which permits dayin the building back of the permanent wall 2. These windows must be placed at one side or the other of the advertisements, or above or below them so that wherever they are placed in the permanent wall they will not interfere with the reflecting enamel paint or other light reflecting surfaces that are placed either directly on the permanent Wall or that stands up against it, thus in Figures 1, 3, 4 and 9.

The white enamel paint light reflecting surface is illustrated applied on the outside surfaces of the permanent wall so that the electric light is reflected directly onto the rear side of the different colored lenses, but in Fig. 5, I illustrate a large board or sheet of metal G, that is provided with a light reflecting surface, the lower end of which rests on an anchor strap 10, and lean up against the inside surface of the permanent wall, consequently it can be moved around and placed wherever it is desired to have a removable reflecting surface, and in Fig. 5, an advertising design of the lenses is shown below the window l-A, in front of.

the movable reflectin surface G, and the outline of a design of an advertisement or an ornamental design is also outlined on the vertical section of the subfront which extends up from the sidewalk in this view opposite to the white enameled wall surface B of the permanent wall 2.

The roof portion of a building can consist of any of the types or roofs in use and may contain domes or other architectural features with eitherstraight or curved surfaces, and they can be very attractively illuminated with advertising matter by .my system of colored transparencies. My invention'provides a way by which any character of practical lettering for signs and any practical form of an ornamental design may be displayed in illuminated colors, and while'I have illustrated and described the preferred construction and arrangement of my invention, changes may be made in it without departing from the spirit of my invention. Having described my invention what I claim as new and desire to secure by Letters Patent, is
