Abstract: An incremental sheet advertising sign assembly includes a plurality of substantially identical panels to be mounted on a rail frame. Grooved wheels are attached to the back of each panel in such a manner as to engage the uppermost rail of said frame. At least one locking track is mounted vertically along the back surface of each panel, and locking elements slide along the tracks and lock the panel to a lower rail of the rail frame.

Abstract: An advertising billboard is provided and various methods and means of its construction are described and claimed utilizing the basic concept of drawing a sheet of fabric having the advertising message on the front across the rigid billboard panel and then introducing a continuous stream of air, or maintaining a continuous pressure, between the panel face and the fabric to smooth the fabric into a continuous, slightly curved surface without wrinkles or sag lines.

Abstract: A large poster apparatus for a back-lighted signboard and a method of constructing same from a plurality of smaller poster sections, including improving the translucent quality of the poster material, aligning respective adjacent sections for exact image continuity, laminating a clear film over a first poster layer, laminating a second poster layer over the clear film, and applying heat and pressure to create a composite laminated poster apparatus having registered images throughout.

Abstract: A generally rectangular framework is constructed to hold a plurality of individual advertizing panels. The bottom and two sides of the frame are formed from channel members connected at their corners and designed to snugly but freely receive the plurality of panels. A pair of panel support members which are formed as parallel spaced walls extend between the tops of the side channel members and form the top of the framework. Each wall is connected to the ends of the legs of an angle iron member, the apexes of which are facing and spaced horizontally by approximately the width of the panels. The apexes are spaced vertically by an amount to allow the panels to be slid between them at an angular orientation so that the panels can be lifted in an angled position, pulled between the angle iron members, and rotated to a vertical position to be dropped between the sides of the channel member on the bottom of the framework.

Abstract: A three-dimensional figure made from an inflatable, sculptured envelope of soft pliable material into which is blown a constant flow of ambient air wherein said flow of ambient air can be modulated or reversed to cause a lifelike movement of the sculptured figure. The inflatable envelope can be attached to the face of a billboard to create a three-dimensional display which can be quickly assembled or dismantled. The structure can tolerate substantial leakage of air from the envelope along seam lines, through the pliable material fabric or small puncture holes.

Abstract: Apparatus for mounting signboard paper in large sheets or in elongated strips, and for holding the signboard paper in tension over a slightly curved board transparent surface, and including moveable tensioning devices.

Abstract: A sign opening, closing and locking device for use on a conventional rectangular, box-like sign having one or more advertising panels hingably attached to the frame. The device comprises gear racks and pinion, a raceway for containing the racks, linkage from the racks to the front panel, and a crank for rotating the pinion. In operation the crank is mated with a shaft to rotate the pinion. Rotation of the crank and the engaged pinion cause linear movement of the racks and the attached linkage resulting in an initial disengagement of the linkage from a stationary lock pin. Further rotation results in an outward movement of the front panel as it is rotated on its hinges. Opposite rotation of the pinion results in closure and locking of the sign.
