Claim 1
Independent Claim
251 words
An advertising sign, comprising: a verticallY arranged panel having a forward face and a rear face; a pair of horizontally arranged idler rollers arranged axially parallel to the panel, with one arranged at the upper end and the other arranged at the lower end of the panel; an upper and a lower horizontally arranged, rotatable wind-up roller arranged at the rear face of the panel; each wind-up roller being rotatably mounted at its ends upon roller mounting brackets secured on the opposite ends of a horizontally elongated strip; and a horizontally directed pivot connecting each strip to the rear of the panel, with the axis of the pivot arranged perpendicular to the center of the axis of the wind-up roller whereby each of the wind-up rollers pivot in a vertical plane about a horizontal axis which is perpendicular to both the panel and the center of the central axis of said wind-up roller; and means interconnecting said two strips so that they pivot together with their respective wind-up rollers remaining axially parallel; a long, wide, flexible, cloth-like sheet having messages applied upon its surface along its length, with the sheet extending across the panel forward face, and its opposite ends extending around the idler rollers and wound-up upon the wind-up rollers, the sheet being of sufficient length so that rotation of the wind-up rollers advances the sheet in a generally vertical direction upon the panel for exposing various message bearing portions of the sheet upon the forward face of the panel.

An advertising sign, comprising: a verticallY arranged panel having a forward face and a rear face; a pair of horizontally arranged idler rollers arranged axially parallel to the panel, with one arranged at the upper end and the other arranged at the lower end of the panel; an upper and a lower horizontally arranged, rotatable wind-up roller arranged at the rear face of the panel; each wind-up roller being rotatably mounted at its ends upon roller mounting brackets secured on the opposite ends of a horizontally elongated strip; and a horizontally directed pivot connecting each strip to the rear of the panel, with the axis of the pivot arranged perpendicular to the center of the axis of the wind-up roller whereby each of the wind-up rollers pivot in a vertical plane about a horizontal axis which is perpendicular to both the panel and the center of the central axis of said wind-up roller; and means interconnecting said two strips so that they pivot together with their respective wind-up rollers remaining axially parallel; a long, wide, flexible, cloth-like sheet having messages applied upon its surface along its length, with the sheet extending across the panel forward face, and its opposite ends extending around the idler rollers and wound-up upon the wind-up rollers, the sheet being of sufficient length so that rotation of the wind-up rollers advances the sheet in a generally vertical direction upon the panel for exposing various message bearing portions of the sheet upon the forward face of the panel.
Claim 3
Dependent Claim
45 words
A construction as defined in claim 1, and said means interconnecting the two strips comprising a link extending between and having its opposite ends connected to their adjacent strips, with each end connection aligned with the axis of the wind-up roller of the respective strip.
Claim 4
Dependent Claim
70 words
A construction as defined in claim 1, and including sensing means for detecting misalignment between an edge of the sheet and the idler rollers and for actuating a power means connected to and arranged to move at least one of said strips about its pivot and thereby pivot the wind-up rollers, for applying a transverse force upon the sheet to cause realignment as the sheet rolls over the idler rollers.
