This invention relates broadly to sign construction and more specifically to an advertising medium popularly known as the pylon or tower type of signs. Such structures comprise generally a 6 monumental shaft or obelisk adapted to be illuminated from the interior and provided with transparent side walls exposed to view from all sides and bearing the decorative, ornamentative and advertising indicia.

10 One of the objects of this invention is to provide a sign of the above type which embodies certain improved features of construction, minimizes the cost of production and erection and in addition possesses an attractive and aesthetic appearance.

15 Another object of this invention is to provide a sign of the interiorly illuminated type which is capable of more effective and uniform light diffusion than known signs of this class.

Another object of this invention is to provide a 20 sturdy and durable structure which Will form an attractive pylon or analogous internally lighted display device and which is so constructed that it may be operated at a relatively low cost as compared with the construction and operating 25 costs of comparable advertising structures.

A further object of this invention is to provide a sign of the above type in which the interior framework adequately strengthens and reinforces the sign and at the same time more effectively distributes the light within the structure.

The foregoing and other objects and advantages will become apparent in view of the following description taken in conjunction with the drawings, wherein- 35 Figure 1 is a view in elevation of a sign of the pylon type constructed in accordance with the present invention.

Figure 2 is a view in central vertical section of the sign shown in Figure 1.

40 Figure 3 is a plan view of one of the metal sheets or plates from which the central framework of the sign is constructed and Figure 3a shows the plates illustrated in Figure 3 configured into the desired form for installation with a companion sheet in the sign.

Figure 4 is an enlarged fragmentary sectional view taken on a plane indicated by the line 4-4 of Figure 1.

50 Figure 5 is an enlarged View of one of the corner portions of the structure illustrated in Figure 4.

Figure 6 is a fragmentary longitudinal section (with portions broken away) of the upper and lower extremities of the pylon sign.

5,5 Figure 7 is an enlarged fragmentary longitudinal sectional view of an intermediate portion of the sign.

Figure 8 is an enlarged detailed sectional view of one of the frame or muntin sections and adjacent panels showing the preferred method of 5 mounting the glass.

The sign, as shown in Figure 1, is mounted upon a base or pedestal 5 which may be of concrete or suitable masonry, the type of sign shown in Figure 1 being what is known as the pylon 10 sign. The body of the sign comprises a central frame structure supporting an outer framework which retains transparent or translucent panels. These panels are illuminated by incandescent lights or other means from within the sign. The panels may bear advertising indicia of any desired type, such indicia being applied on the inner or outer surface of the glass or material forming the panel.

Referring to Figure 3, a fabricated sheet or 2 plate 6 is shown, which may be of such length and breadth as to accommodate the desired height and breadth of the pylon after the forming or bending operation thereon. In the present case a single sheet is shown although it will be obvious that a plurality of sheets may be employed and joined in any suitable manner, as by welding, to obtain a frame of required dimensions. The sheet 5 is fabricated in the central portion with a plurality of holes I. The sheet is then bent longitudinally to form an angle iron, note particularly Figure 4, and also with the edge portions thereof bent to form attaching flanges 8. In constructing a complete unit, two blanks or sheets 6 are preferably employed, each blank being substantially identical and shaped in substantially the same manner. The formed sheets are then arranged with the apices of the angles contiguous and secured preferably by welding as at 9. The resultant structure forms an X in cross section having four projecting wings with flanged edges which support the outer sheathing materials.

The outer framework comprises a series of skeleton frame sections which are preferably, but not necessarily, of extruded aluminum bar stock. At each corner of the pylon an upright frame section or corner post is provided which is substantially C-shaped in cross-section and externally configured to present an attractive ap- 5O pearance. Within the corner post there is an anchor member for supporting the central X- frame. This member may be in the form of a channel I! and is preferably disposed with the flanges thereof turned outwardly in order to retain and prevent rotation of the bolts 12 mounted thereon. The flanges 8 of the wing portions of the outer frame plates 6 are secured to the channel I l by the bolts l2. Washers or analogous thrust members or shims !3 may be inserted between the flanges 8 and corner pieces ID to facilitate more expeditious assembly and to compensate for structural error or distortion.

At the base of the sign, the corner posts or plates ID are secured to or interlocked with base plates [4, note Figure 6, which are also preferably of extruded material such as aluminum and are secured to a continuous angle iron frame l5, anchored to the foundation or base by lug screws or studs 16.

The top of the skeleton framework comprises a header plate or frame section I! to which each of the corner members or posts ii] are secured, each of the plates il being secured to a continuous angle iron frame member I8. Above the angle I8, and supported by .a series of brackets 20, there is a cap [9 which may be formed of sheet metal or other material susceptible of suitable configuration and decorated. Each of the brackets 28 is preferably formed of a bent bar stock having legs 26a and 28b, the leg 20a resting on the angle [8, and the leg 28b upon the lower flange I9a of the cap. The upper portion of the bracket bears against the top wall of the cap and serves to brace the cap as a whole and rigidly support the latter in its associated relation with the frame sections l1 and I0.

A series of panels 2 i, which are preferably transparent or translucent, are attached at their side edges to the corner sections it and at their upper and lower edges to muntins 22, note particularly Figure 8, by means of suitable caulking material 23. The muntins 22 are each supported by a continuous band 24 formed with a series of spaced anchor ribs 24a adapted to engage corresponding grooves formed in the inner face of each of the muntins. The bands 2 may be secured to the corner posts ID or may be bolted to the channel iron I I. If it is desired the panels in one side of the pylon may be hinged to facilitate removal of light bulbs or repairs.

The lower portion of Fig. 8 shows a means for securing the panels 21 in readily removable position, said means consisting of a sash 23a which is secured to the muntin 22 by means such as screws 23b. The sash may obviously be replaced by a series of wedge blocks, if desired.

Adjacent the top of each of the apertures 1 of the plates 6 there is an electrical junction box .and 'light socket 25 secured by a clip 25, which may be clamped or otherwise secured upon the wings of one of the plates 6. A conduit 2! is assembled in one of the corners of the pylon and may be secured to the framework thereof in any suitable fleeting surface, or may be formed from a material of inherent reflecting qualities so that the light rays will be directed in such a manner as to materially aid in illuminating the sign. The wings of the central frame member also serve to more evenly distribute the light rays with respect to the panels 2!. The construction of the censign may be made attractive in appearance without adding to the cost thereof. Another advantage is that the construction is relatively light while at the same time it is strong and rigid and capable of withstanding the elements over a long period of time.

It will be understood that any desired number of angle-shaped members 6 may be employed to produce the desired polygonal configuration and that various other modifications and changes in structure may be adopted without departing from the scope of the invention as defined by the appended claims.
