structure which may be readily knocked down,

or altered in shape, size ,and design, and which lends itself readily to variation-in the display features by permitting. a quick and ready. change of elements forming a portion of the display,

whether illuminable or not, as well as ail'ording a ready means for varying the actual physical structure other than the display portions thereof.

In the variation of the structure it is contemplated that the display elements will be arranged in groups ofreadily interchangeable units,-

and that the individual elements may be changed and interchanged within a unit, and from unit to unit, to the end that various compositions and arrangements may be made with the same or additional display elements and units.

- It is also an object of the invention to produce a series of standard parts which may be formed in a variety of lengths and shapes so designed that an infinitesimal number of sizes, shapes and designs of completed structures may be formed,

constructed or assembled from the same or like parts, either-with or without the subtraction or addition ofelements.

Another object contemplates a method of as-' sembling the parts efliciently and economically to produce a great number and variety of structures from standard parts, which structures will 40 be pleasing in appearance and productive in reasonable quantity at low cost; and which method will permit quick dissembling of all or part of any structure for the purpose of shipping, repair, service, replacement of any part, or change of design. In a copending application, Ser. No. 107,493, filed October 24, 1936, there is disclosed a method of shaping, curving, bending and polarizing sections or pieces of glass, crystal or equivalent transparent and translucent, light transmitting material for the production of sign elements, in which light may be transmitted through an edge of said. element in one direction and carried through another plane of the element to illuminate a letter or design which may be etched or sand-blasted upon a surface of the element,

,and an important feature of the present invention resides in the production of a type of sign, display, advertising or decorative structure,

- which is particularly designed and adapted'to'the 5 use of such curved or bent elements, and upon which elements, the letters, compositions, designs, etc., have been etched or sandblasted upon a sur-. face in a planeat an angle to the axial surface or length thereof. 1 That is to say, it is contem- 10 plated that the present invention isparticularly adapted to theuse of polarized glass elements having angularly I disposed portions extending through at least two planes and upon one of which portions is placed a design. Such an element 16 lends itself well to illuminating efiects and permits thev transmission of light through an edge of an angular portion for transmission tothe design upon the other surface, and the element per se forms an important part of this invention. 20

The objects of the invention further include the production ofa structure in which suchcurved or bent glasssections may be easily removed, replaced, changed and interchanged in various sizes, positions and arrangements without changing or adjusting the main structure of the device, and contemplate a-method of inserting or applying said sign elements in position so that the inserted edge of a radial axis of the element is exposed to a source of light.

Still another object of the invention resides in a sign structure comprising acurved or bent section of glass or equivalent light transmitting vitreous material having a letter, design, or other composition etched or sandblasted thereon, and having the edge of the radial axis of said glass inserted or'held in the signal structure in such a manner as to expose that edge to a source of lightgand causing the sandblasted or etched portion to be illuminated on a substantially vertical plane from the light source disposed at right angles or horizontal thereto with respect to the illuminable portion.

In addition to the arrangement of standard parts and assemblage thereon, interchangeably, the objects of the invention include in a such a sign structure,-a series of curved or bent sections having individual letters, designs, etc., thereon andilluminable, as heretofore set out, which sec-- tions are changeable and interchangeable so as to form new compositions with the same or additional sections, and adapted for arrangement in groups each forming a unit, and for changing and interchanging the sections not only. with an individual unit but from one unit to another.

To this end, means are provided for supporting the sections solidly, but in such a manner as to permit ready removal and replacement thereof within the sign structure.

1 It is also contemplated that the sign or other structure of this invention will be of the type particularly designed and constructed to facilitate the changing, interchanging, and illumination of the said sections to form a variety of compositions and arrangements with the same or additional sections, and to facilitate changing and interchanging a variety of sizes of illuminable sections, as well as to facilitate changing and interchanging the groups or units of compositions, and the color or colors of the illumination of said compositions. I

One of the important features of the invention resides in the type of curved or bent glass or light transmitting vitreous material, having a certain degree of so-called polarization or internal reflection over and through the area where the bend occurs, the elements being polarized, in a manner that permits only those rays of light. which are projected in a plane parallel to the opposing surfaces of the glass from an axial edge thereof to pass through and beyond said bent area, and in illuminating the etched or sandblasted section which is disposed at right angles to the axial edge and surfaces thereof, while restricting the passage of light rays which are projected on other planes not parallel to the radial surfaces of the bend. For a description of the method or manner ,of furnishing polarization, reference may be made to my co-pending application, Serial No. 107,493, above mentioned.

The restriction of these non-parallel rays at the bend prevents their escape which otherwise would impair the effectiveness and visibility of the internal illumination of the sandblasted portion.

From a structural standpoint, the invention also includes means for preventing light being conducted along and reflected from the marginal port ons of the element bordering the edge where illumination is introduced.

To the attainment of the foregoing and other objects which will appear as the description proceeds, reference may be made to the accompanying drawings, in which:

In explaining the manner of assembling a sign, or other structure of the type referred to, it should be noted that the purpose of this method of construction, and the design of the parts adapted thereto is one that possesses the advantages of fabricating standard parts for a large variety of structural arrangements and sizes and greatly improves the methods employed in ordinary sign or tin shop practice.

All of the structural elements going to the make-up of the structures may be designed as standard parts, not limited to use solely in one position or location, but adapted for arrangement in various combinations, units, or groups of parts to form various effects either in horizontal or vertical positions. They are adapted to single or multiple lines of compositions in a variety of sizes and illuminable color effects relative to the compositions and combinations thereof.

Referring now to the drawings, in which like reference numerals designate like parts, there is shown for purposes of illustration a sign such as might be used for lunch room or cafe display. This sign comprises generally a supporting enclosure or frame formed of a base l0, an upright standard or support H at either end, and a top l2, within which will be arranged a variable dis- 1 play consisting of a desired composition, illuminated from vthe rear, and arranged so that the rays of light will be passed through the display. A top d splay may be provided, the display element l3 thereof being positioned to receive illumination through its lower edge from the same or similar source of illumination for the main or central display.

A back plate l4 serves to complete the general member I! may assume the form of a channel iron of a depth approx mating the width of the flange I60, and the member l8, which forms a key for cross members, hereinafter described. may be'a channel iron of a depth approximating the width of the flange lGb. The member I9 is in the form of a, stepped angle iron having an overall width approximating that of the flange I 8b, and is used to hold the back plate ll in position.

If desired, a foot plate or shoe 20 (Fig. 1) may be provided for the base of an upright unit II. this shoe 20 being merely an angle bracket which may be positioned with one flat side across the base of the unit, and the other flat side extending upwardly againstan upright wall of the unit, such as an inner face of the member ii.

To assemble the structural members and form a complete upright, one vertical flange of the member 19 will be secured to the outer face of the flange Nb andany convenient manner, as by welding, and the shoe or foot plate 20 is then welded or otherwise attached to one end a: the member I! to provide a support therefor. Two such units, one right and one left, are then of the foot plate or *shoe 20.

The channel iron I! may then be inserted with its open side against the inner face of the member 2 and secured in place. a

The variable display itself, within the enclosure or frame, and the illuminating media therefor, are supported by a series of cross members which may be assembled into units to form as many rows or lines as may be desired in a given structure, and by particular reference to Figs. 2, 3 and 8 the nature of these cross members may be bestobserved.

The main member of each unit is a reticulated or lattice-like channel iron 23, the edges of which are turned inwardly to form flanges 24, the side wall opposed to the flanges 24 being cut out to form flange-like portions 25 separated by struts 29. Spacer channel irons 21, cooperative therewith, are formed with out-turned edges, providing flanges 28. The dimensions of the members 23 and 21 are relatively proportioned such that the member 23 may rest on one side wall of the member 21, with a flange portion 25 extending coextensively with aflange 28, without however obscuring the reticulated portion towards which i the flange 28 extends.

The member 23 serves to enclose and support a gripping means for securing the display elements. in position. This means comprises a pair of opposed resilient friction members 29, preferably formed of strips of rubber, or like material extending throughout the length of the member 23 and clamped in place by .a pair of channel irons 33 which may be interleaved in inverted relation, as best shown in Fig. 3; Naturally, the proportions of the channel iron and the thickness of the strip 29 will be such that when assembled the strip will be clamped in position. Duplicate units .each comprising a strip 29 and channel irons 30 and 3| will be provided for each cross member 23, one unit being placed in the top between the flanges 24 and 25, andthe other unit being similarly placed in reverse position in the bottom of the member 23.

A bottom cross member 32 similar to the member 21 is provided, this member 32 having butone edge turned outwardly to form a flange 33 similar to theflange 28. A top member 34 in the form of a stepped angle iron serves to complete the main series of cross members or units. In assembly of the cross members with the main supporting enclosure or frame,'it is simply necessary to place the member 32 on the base It], with its ends extending into the enclosures of the right and left structural members IS. The closed side of the member 32 will extend across the rear of the channel irons ll, into engagement with the inner faces of the members l6. Then an assemblage consisting of the reticulated member 23 with the strips 29 and clamping members 39-- 3l will be placed on top of the member 32, the flange portions 25 and struts 29 being disposed toward the rear, and the strips 29 toward the front of the structure. top of this unit may be placed a spacing member 21, with its open side and flanges 23 toward the rear. The spacer 21 may be topped with another reticulated unit 23, and these spacing members 21 and reticulated units may be stacked upon and parallel to each other until the desired height, 1

and number of rows of design are attained. The stack may then be surmounted with the top member 34 to equal the total height of the up! 3 right assembly II. This mei iiber u may be suitably bolted to the upright columns ii through openings Na and 34a by 'a'"bolt 35.

Once the stack of cross members is assembled,

with, their ends extending into the respective uprights Ii the channel iron l8, which forms a key for holding the cross members in place, may be forced into the right and left hand channels of the uprights ii, and between the rear internal surfaces of the flanges lib of said channels and the rear of the stacked up cross members, thereby to force the front surfaces-of the cross members against the rear of the channel member H which, of course, has previously been insertedin the member l6.

If no top display is desired, the assemblage is now capped ,by the member i2, but in the preferred form where it is desired to provide a top display l3, a unit similar to the reticulated unit 23 is first mounted on the stepped member 34. 20

This unit will be positioned with the reticulated or cut-out side of its member 23 downwardly, and

instead of a single pair of strips 29 and clamping irons 30-3 l two or more superposed sets of strips and clamping members may be used, to afford the 25 necessary strength for holding the display ele--' ment l3 in position. Any suitable spacing and holding means, such as composition or rubber blocks 36, may be secured at the rear of the top display holding unit, to brace same. so

Illuminating means are provided at the rear of the stacked cross members, preferably in the form of neon, or equivalent gas tubes 39, and

. while not essential, these illuminating tubes are desirably clamped adjacent to andacross the reticulated portions of the members 23. This is effective to block passage oflight along and reflected from marginal portions of the display elements.

Suitable leads 40 serve to supply current from a control box H which may serve to house any conventional form of flasher, or other control mechanism for producing variable illuminating effects.

The display itself is preferably in the form of curved or bent elements of glass, crystal, or equivalent transparent or translucent vitreous material, upon which letters, compositions, de' signs, or the like, have been etched or sandblasted upon a surface at right angles, or any intermediateangle, to the axial surface or length thereof. I

In Fig. 9, such an element 44 is illustrated. and it will be observed that this element comprises amain body portion or surface 45, carrying a letter 48, and a flange 41, angularly disportion 49 thereof and down through the body .70

portion 45, producing a very pleasing effect on the, etched or blasted letter 43. 1

A series of'these elements 44 may be readily inserted and-removed from the face of the entire structure, merely by forcing the portion 4] g;-

laterally between strips II, which conveniently yield to receive same andfrictionally hold the elements 44 in position.

If the display is to be used outdoors, an upper one of the strips 29 may be bent outwardly, in-

stead of inwardly, as illustrated in Fig. 4, to

afford a rain shed, and to protect the display from the weather.

The element It will, of course, be similarly inserted from the top of the structure through a suitable slot Ila, as will be seen from Fig. 3, until the lower edge thereof rests in part upon the cross member 34. The space afforded between the rear of the cross member 34 and the flange portion of the top reticulated unit permits light to reach the element i3, from within the structure.

The foregoing description of a preferred form is, of course, not intended as limiting but as illustrative of one mode and arrangement of sign elements. Many modifications will occur to those skilled in the art, and as illustrative of an alternate construction embodying the inventive features, reference may be made to Figs. 11 to 14, inclusive, wherein an alternate "sign face assembly is illustrated. Where elements of these figures are the same as the elements of Figs. 1 to 9, the same reference numerals are used; where additional elements are introduced, new reference numerals have been applied.

A principal portion of this alternate face assembly is shown in Fig. 13, wherein l9 designates a face or spacer plate secured to a channel member 50 in any suitable manner, as by spot weld-' ing. The member 50 comprises a pair of shoulders or angles II which are shaped to merge into walls 62 disposed in substantially parallel relation to the main body portion of the channel member 50. The walls 52 will be oppositely spaced 9. predetermineddistance on both sides of. and formed as part of the body of the member Bil, whereupon when the spacer plate 49 is longitudinally secured to the body of the member 50, as shown in Fig. 13, a pair of channels or grooves 54 will be formed. In Fig. 12 is shown one of the strips 29 which, when placed in a channel 54 and wedged or snugly fitted therein by means of a strip 55 (corresponding somewhat in function to the channel clamps serves to complete the. assembly of a cross member. This cross member corresponds to the cross members illustrated in Fig. 8.

, the element I 6 against the face of the member H, when positioned properly therein and clamped at both ends by the member II.

A preferred method of arranging the cross member assembled to form a sign face of any predetermined size is shownclearly in Fig. 10, wherein the cross assemblies are arranged in the desired number and length upon the face of the channel element l1, and secured in fixer. position thereto by spot welding, or bolting. (Spot welding is illustrated in Fig. 11.)

It will thus be observed that the parts If, 49 and may be fastened together in one operation and that all of the parts for any mode of assembling are adapted to standardization, and. may be cut to any predetermined length just as the form illustrated in Figs. 1 to 8.

As shown in Fig. 10, each of the pair of strips 2|, positioned in the channels ll, of a cross assembly serves to close one-half of one retaining slot for the display element 44, and the other half is similarly closed by a strip 28 in an adjacent cross assembly, all of which is quite similar to the arrangement of Figures 1 to 8. This permits a variable spacing of the retaining or gripping slot adapted to receive a display element 44 of any predetermined thickness.

The use, advantages, mode of assemblage and operation will be obvious from the foregoing. The parts necessary for a given structure are standard and interchangeable in the construction of other signs of different size, shape and style. All parts can be carried as stock, and no special elements are necessary for any individual structure. Hence it follows that the designs of one complete sign may be dismantled and the parts used in the construction of a different assemblage. Because of these features, a method of assemblage that is efllcient, pleasing in appearance, and economical in production is afforded, permitting a great number and variety of structures to be formed from standard parts at low cost in reasonable quantity.

By the same token, quick disassemblage for purpose of shipping, repairs, service, or replacement, is obtained.

With all of these advantages, there is found the additional factor of a very attractive sign display, or advertising device in which an individual design may be readily varied and changed without disassembling the component structural elements of the frame or individual supports for the display members.
