Folding school bus stopping arm

Claim 3

The method as defined in claim 1 further deactivating the warning devices by the steps of: g. de-activating the warning signal from the drivers position, h. retracting the gate responsive to said warning signal de-activating until the gate is in a retracted position, j. retracting the stop sign responsive the gate reaching a retracted position, k. continuing retracting the stop sign until the stop sign is in a retracted position, l. silencing the alarm responsive to the stop sign reaching the retracted position, and m. extinguishing the stop lamps responsive to the stop sign reaching the retracted position.

Claim 4

On a school bus having i. a driver side, ii. a passenger door opposite the drivers side, iii. a movable stop sign on the drivers side, and iv. a movable gate at the rear of the bus on the drivers side, an electrical circuit for controlling the extending and retracting of the sign and the gate laterally from the side of the school bus, said circuit comprising in combination with the above: a. a door switch mounted upon the passenger door of said school bus, b. a timing device connected to said door switch, c. said timer having a set of delay contacts which have a delayed response, d. a delay relay attached to said set of delay contacts, and e. a gate electric motor for extending the gate electrically connected to said delay relay, f. instantaneous contacts on said timing device, said instantaneous contact actuating g. an instantaneous relay, h. a sign electric motor to give a visual signal by extending said sign, said sign electric motor electrically connected to contacts of said instantaneous relay, j. a sign switch activated by movement of the sign, k. an audible signal device electrically connected to said sign switch, l. the timing device and delay relay forming a portion of means for delaying the extension of the gate until after the sign switch is activated, so that an audible signal is given and a visual signal is given that the gate is being extended laterally from the side of the bus.

Claim 5

On a school bus having i. a driver side, ii. a passenger door opposite the drivers side, iii. a movable stop sign on the drivers side, and iv. a movable gate at the rear of the bus on the drivers side, an electrical circuit for controlling the extending and retracting of the sign and the gate laterally from the side of the school bus, said circuit comprising in combination with the above: a. a door switch mounted upon the passenger door of said school bus, b. a timing device connected to said door switch, c. said timer having a set of delay contacts which have a delayed response, d. a delay relay attached to said set of delay contacts, and e. a gate electric motor for extending the gate electrically connected to said delay relay, f. instantaneous contacts on said timing device, said instantaneous contact actuating g. an instantaneous relay, h. a sign electric motor to give a visual signal by extending said sign, said sign electric motor electrically connected to contacts of said instantaneous relay, j. a sign switch activated by movement of the sign, k. an audible signal device electrically connected to said sign switch, l. the timing device and delay relay forming a portion of means for delaying the extension of the gate until after the sign switch is activated, so that an audible signal is given and a visual signal is given that the gate is being extended laterally from the side of the bus.

Claim 6

The invention as defined in claim 3, further comprising: m. a lamp electrically connected to said sign switch, n. a blinker mechanism electrically connected to said sign switch, o. at least two sets of lamps attached to said blinker mechanism, p. said blinker device alternately lighting one or the other of said sets of lamps and said lamp lighting when said sign switch is activated.
