UNITED STATES DAVID W. COYLE, F PASADENA, CALIFORNIA.
Application filed April 15, 1922. Serial No. 552,831.
To all whom it may concern:
Be it known that I, DAVID W. CoYLn, a citizen of the United States, residing at Pasadena, in the county of Los Angeles and State of California, have invented new and useful Improvements in Advertising Signs, of which the following is a specification.
This invention relates to advertising apparatus and more particularly to! sign boards.
0 It is an object of the present invention to provide an improved sign board whereby the primary supporting structure may be permanently erected while the advertising panel or panels may be interchanged as de: sired at comparatively small expense. An
object is to provide a sign board of simple and substantialconstruction and at the same time being of economical cost.
One embodiment of the invention is herein described and illustrated in the accompanying drawings, in which- Figure 1 is a perspective of an erected sign board complete.
Fig. 2 is a detail sectional view of a pivotal form of panel support, the section being along the axis of the pivot.
Fig. 3 is a transverse section of the modification shown in Fig. 2.
My improved sign board includes substantially supported end posts 2-2 arranged in a common plane to provide for the insertion and removal of the main panel board. The panel board consists of the panel 4 which is surrounded by a suitable frame 5.
The invention is shown in Figs. 2 and 3 in which the rails 8 may be, either or both, tiltable along their longitudinal axes, and to that end they are mounted on substantial pi ot members in the form of bolts of which one is shown at 15 passing through the top 01'? the post 2 and extending into the top rail 8. The top rail is provided with a notch 8 to receive the nut 16 on the end of the bolt 15 passing through the post 2. Pairs of molding strips 9 are provided. on the inner faces of the rails 8. In this case the bolt pivotally supports the rail 8 and this can, be tilted on the axis 01" the bolt to the position shown in dotted lines in Fig. 3, at which time the upper edge of a panel 4 can be inso serted into the channel between the top molding strips 9, and then the panel and the top rail 8 can be rolled back into vertical interlocking and supporting position after which the fastening bolt is tightened up.
s shown in Figure 2, the post 2 is not provided with vertical molding strips 9, and when such strips are provided, as shown in Figure 1, they are removable to provide for change of signs.
Various changes and modifications may be made without departing from the spirit of the invention as claimed.
What is claimed is:
1. In a sign board, permanent supporting posts, pivot bolts axially arranged in said supporting posts, upper and lower rail members mounted upon said'bolts and between said posts and adapted to be rotated thereon, and a panel member adapted to be interlocked with the rail members and secured thereby in upright positionwhen said bolts are tightened up.
2. In a sign board, permanent supporting posts, pivot bolts axially arranged in the heads of saidsupporting posts, an upper rail member mounted upon said bolts and between said posts and adapted to be rotated thereon, a lower rail secured to the posts, 8 and a panel member adapted to be interloclced with and between the rail members and secured thereby in upright position when said bolts are tightened up.
In testimony whereof I have signed my name to this specification.
DAVID W. COYLE.
