A coin operated electric lamp, including an electric circuit, having a plug for connection to a household electric power supply; the circuit including a switch activated by a deposited coin, so to close the circuit to an incandescent lamp bulb and to a motor in parallel to the lamp, the motor driving a spiral cam which, upon completing a rotation, pushes the switch into an open position so to stop the motor and turn out the light bulb.
Claims6
A coin operated electric timer, comprising in combination, an upper and a lower case secured together, a coin slot in said cases receiving a coin, a pivoted lever tripped by said coin, a pivoted arm carrying two contacts, being pivoted by said lever so as to contact a pair of stationary contacts connected to a socket fitted with a lamp bulb, and said arm contacts being connected to a power source plug.
An electric timer comprising, in combination, a case, a pivoted arm carrying two contacts contained in said case, said pivoted arm having two stable states, and toggling means for pivoting, said pivoted arm between its two stable states such that said contacts are closed against a pair of stationary contacts in one state and open in the other state, and which further comprises a motor unit mounted on said case, which rotates a first cam and a second cam wherein said first cam stores energy in a spring means and said second cam releases energy in said spring means.
