Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
217 words
A luminous publicity display comprising a drive roller; an idler roller spaced from said drive roller; a continuous image carrying sash mounted on said drive and idler rollers for rotation thereby; a drive motor operatively coupled to said drive roller for the rotation thereof; switch means; and end-of-display member associated with each image on said sash and positioned on said sash for operative engagement with said switch means when its associated image is substantially in a viewing position; time delay circuit means operatively coupled to said switch means and drive motor for actuation by said switch means and for stopping said drive motor upon such actuation, and restarting said drive motor a predetermined period of time thereafter; curtain means mounted for displacement between an open and a closed position relative to said image viewing position; means for biasing said curtain means in said closed position; and curtain drive means coupled to said drive roller for maintaining said curtain means in said open position when said drive motor is stopped, for releasing said curtain means when said drive motor starts to permit said curtain means to assume its closed position, and for displacing said curtain means from said closed to said open position in response to the rotation of said drive motor during the displacement of said sash.
Claim 2
Dependent Claim
217 words
A luminous publicity display comprising a drive roller; an idler roller spaced from said drive roller; a continuous image carrying sash mounted on said drive and idler rollers for rotation thereby; a drive motor operatively coupled to said drive roller for the rotation thereof; switch means; and end-of-display member associated with each image on said sash and positioned on said sash for operative engagement with said switch means when its associated image is substantially in a viewing position; time delay circuit means operatively coupled to said switch means and drive motor for actuation by said switch means and for stopping said drive motor upon such actuation, and restarting said drive motor a predetermined period of time thereafter; curtain means mounted for displacement between an open and a closed position relative to said image viewing position; means for biasing said curtain means in said closed position; and curtain drive means coupled to said drive roller for maintaining said curtain means in said open position when said drive motor is stopped, for releasing said curtain means when said drive motor starts to permit said curtain means to assume its closed position, and for displacing said curtain means from said closed to said open position in response to the rotation of said drive motor during the displacement of said sash.
Claim 3
Dependent Claim
43 words
A luminous publicity display as recited in claim 1, wherein said time delay circuit means includes a condenser connected for charging upon actuation of said switch means and a variable resistance coupled to said condenser for adjusting the duration of said time delay.
Claim 4
Dependent Claim
143 words
A luminous publicity display as recited in claim 1, wherein said curtain drive means includes a curtain roller operatively coupled to said curtain means and mounted for rotation relative to said drive roller; a displaceable pawl mounted on said curtain roller; a pulling pivot mounted for rotation with said driving roller in the path of said pawl for carrying said pawl and curtain roller therewith to open said curtains and for retaining said pawl and curtain roller for maintaining said curtains in said open position; and a pusher pivot fixedly mounted in the path of said pawl for engaging said pawl as it is carried thereby to displace said pawl out of the path of said pulling pivot to permit the free rotation of said curtain roller and the displacement of said curtains to said closed position in response to said biased means.
Claim 5
Dependent Claim
54 words
A luminous publicity display as recited in claim 3, including an idler roller and cord means extending about said curtain roller and idler roller and secured to said curtain means for coupling said curtain means to said curtain roller for positioning of said curtain means in response to the rotation of said curtain roller.
Claim 6
Dependent Claim
85 words
A luminous publicity display as recited in claim 1, wherein said switch means comprises a fixed contact and a sprIng contact, said spring contact being positioned normally out of engagement with said fixed contact in the path of said end-of-display members for displacement away from said fixed contact, and flexing toward and into momentary engagement with said fixed contact upon release by said end-of-display members, said spring contact being adapted to rebound from said fixed contact to assume its initial position out of engagement therewith.
