Scrolling sign with improved web guide

Claim 2

An improved guide means for a scrolling sign having a framework and a sign face with a window in which indicia may appear, a pair of rotatable web rolls with a web containing serially arranged indicia wound thereon, said web extending along a path between the web rolls and across the window for selectively displaying indicia in the window, said guide means comprising: a pair of plate-like members, said members lying along the path of the web and spaced from each other along the path, said members receiving the web, at least along an edge of each of said members, said web extending between said members from one member of said pair to the other member of said pair, said members lying parallel to each other and generally normal to the portion of the web extending between said members; brace means mounted to and extending between said plate-like members for joining said members into a unitary structure, said brace means extending between said plate-like members at a location removed from said edges of said plate-like members receiving the web so that the portions of said members containing said edges receiving said web are cantilevered beyond said brace means, adjustable length means extending between said cantilevered portions of said plate-like members, said adjustable length means establishing the distance between said plate-like members in a direction parallel to the path of the web; and means suitable for mounting said unitary structure containing said plate-like members on said framework so that said guide means positions the portion of the web extending between said members across the window.

Claim 3

The improved guide means according to claim 1 wherein said edges of said members receiving the web are rounded.

Claim 4

The improved guide means according to claim 1 wherein, at least, said edges of said members includes means for reducing friction between the web and the members.

Claim 5

The improved guide means according to claim 1 wherein said guide means is formed of light transmitting material.

Claim 6

The improved guide means according to claim 4 wherein said guide means is formed of transparent material.

Claim 7

The improved guide means according to claim 1 wherein said members contain projections extending from said members beyond the web when the web is received on the members.

Claim 8

The improved guide means according to claim 1 wherein said members contain light baffles proximate the edges of said members receiving the web, said baffles being spaced from said members so that the web can pass between said members and baffles.

Claim 9

The improved guide means according to claim 1 including a further plate-like member mounted on said brace intermediate said pair of plate-like members for supporting the web between said pair of members.

Claim 10

The improved guide means according to claim 8 further including a retainer means for said web mounted on said further plate-like member.

Claim 11

The improved guide means according to claim 1 including a pair of plates lying normal to said pair of members at either end thereof, said members being fastened to said plates, wherein said web rolls are mounted on said plates, whereby said pair of members, web rolls, web, and plates comprise a modular structure mountable in said sign.

Claim 12

The improved guide means according to claim 10 wherein said members contain inserts for receiving fasteners extending through said plates for fastening said members to said plates.

Claim 13

In combination, a scrolling sign having a framework and a sign face with a window in which indicia may appear, a pair of rotatable web rolls with a web containing serially arranged indicia wound thereon, said web extending along a path between the web rolls and across the window for selectively displaying indicia in the window, and a guide means for said web, said guide means comprising: a pair of plate-like members, said members lying along the path of the web and spaced from each other along the path, said members receiving the web, at least along an edge of each of said members, said web extending between said members from one member of said pair to the other member of said pair, said members lying parallel to each other and generally normal to the portion of the web extending between said members; brace means mounted to and extending between said plate-like members for joining said members into a unitary structure, said brace means extending between said plate-like members at a location removed from said edges of said plate-like members receiving the web so that the portions of said members containing said edges receiving said web are cantilevered beyond said brace means, adjustable length means extending between said cantilevered portions of said plate-like members, said adjustable length means establishing the distance between said plate-like members in a direction parallel to the path of the web; and means suitable for mounting said unitary structure containing said plate-like members on said framework so that said guide means positions the portion of the web extending between said members across the window.

Claim 14

In combination, a scrolling sign having a framework and a sign face with a window in which indicia may appear, a pair of rotatable web rolls with a web containing serially arranged indicia wound thereon, said web extending along a path between the web rolls and across the window for selectively displaying indicia in the window, and a guide means for said web, said guide means comprising: a pair of plate-like members, said members lying along the path of the web and spaced from each other along the path, said members receiving the web, at least along an edge of each of said members, said web extending between said members from one member of said pair to the other member of said pair, said members lying parallel to each other and generally normal to the portion of the web extending between said members; brace means mounted to and extending between said plate-like members for joining said members into a unitary structure, said brace means extending between said plate-like members at a location removed from said edges of said plate-like members receiving the web so that the portions of said members containing said edges receiving said web are cantilevered beyond said brace means, adjustable length means extending between said cantilevered portions of said plate-like members, said adjustable length means establishing the distance between said plate-like members in a direction parallel to the path of the web; and means suitable for mounting said unitary structure containing said plate-like members on said framework so that said guide means positions the portion of the web extending between said members across the window.

Claim 15

The combination according to claim 12 wherein said guide means is formed of light transmitting material.

Claim 16

The combination according to claim 12 wherein said members contain projections extending from said members beyond the web when the web is received on the members.

Claim 17

The combination according to claim 12 wherein said members contain light baffles proximate the edges of said members receiving the web, said baffles being spaced from said members so that the web can pass between said members and baffles.

Claim 18

The combination according to claim 12 including a further plate-like member extending from said brace intermediate said pair of plate-like members for supporting the web between said pair of members.

Claim 19

The combination according to claim 16 further including a retainer means for said web mounted on said further plate-like member.

Claim 20

The combination according to claim 12 including a pair of plates lying normal to said pair of members at either end thereof, said members being fastened to said plates, said plates containing means for mounting said guide means to said framework.
