Abstract
A large sign mounted high on a supporting pole, tower or building is provided with changeable figure sections. Each changeable figure section includes an upper motor driven roller and a lower motor driven roller and an elongate panel of flexible material having digits 0 to 9 thereon with opposite ends of the panel fixed to and rollable on the respective rollers. A three wire motor control system is provided for each changeable figure section that extends therefrom to the ground and on to a remote location with a two way switch where the operator can watch the sign changes he is making. This makes it easier and safer for a person to change letters and numbers on billboards that are dangerous and/or inaccessable to climb up on and work on particularly with a sign high in the air facing the elements.
Claims16
A changeable figure section for an elevated sign controllable from a remote location comprising:
- a changeable figure section in a rectangular box structure having a transparent front window;
- an upper roller and a lower roller rotatably mounted in the top and the bottom of said rectangular box structure;
- an upper and a lower motor in said box structure drive connected to said upper and lower rollers respectively;
- an elongate panel of flexible material having a series of figures along the forward face thereof and upper and lower ends fastened to said upper and lower rollers, respectively, and windable on said upper and lower rollers to varying degrees in advancing the panel up and down to different figure displaying positions with the upper roller driven to draw the panel up when the upper roller is power driven by said upper motor and to draw the panel down when the lower roller is power driven by said lower motor;
- power supply means for said upper motor and power supply means for said lower motor;
- control means line connected for individually controlling power fed to said upper and lower motors from a remote location;
- wherein mounting means is connected to said rectangular box structure for the mounting of said box structure on an elevated sign, such as a tower mounted billboard;
- said mounting means is in the form of criss-cross frame members fastened to the back of said rectangular box structure by fastening means;
- and with said criss-cross frame members formed with hooks at the top for support from a sign transverse frame member, and bottom ends extended beyond the bottom of said box structure for additional mount fastening to the sign.
A changeable figure section for an elevated sign controllable from a remote location comprising:
- a changeable figure section in a rectangular box structure having a transparent front window;
- an upper roller and a lower roller rotatably mounted in the top and the bottom of said rectangular box structure;
- an upper motor and a lower motor in said box structure drive connected to said upper and lower rollers respectively;
- an elongate panel of flexible material having a series of figures along the forward face thereof and upper and lower ends fastened to said upper and lower rollers, respectively, and windable on said upper and lower rollers to varying degrees in advancing the panel up and down to different figure displaying positions with the upper roller driven to draw the panel up when the upper roller is power driven by said upper motor and to draw the panel down when the lower roller is power driven by said lower motor;
- power supply means for said upper motor and power supply means for said lower motor;
- and control means line connected for individually controlling power fed to said upper and lower motors from a remote location;
- wherein said box structure includes top and bottom opposite side box defining members;
- a baffle member spanning the box structure from top to bottom and from side to side within said top and bottom and opposite side box defining members with forward opening upper and lower roller containing chambers and an interim forward flexible panel backing forward projection positioned for the panel to slide along in figure changing movement thereover;
- said interim forward projection of said baffle member defining a rear enclosure of said changeable figure section encloses heating element means used to defrost any frozen moisture on the baffle member tending to freeze said flexible panel to said baffle member;
- and wherein said baffle member is provided with surface deformations to counter baffle surface fluid condensate adhesion sticking of said flexible panel to the forward surface of said baffle member as an aid to free movement of said flexible panel thereover.
