The lever 13 of the ear switrh G will be moved to the right tttlti its eontzletsegment 14 brought into Contact contact 15 ot' the switch, whereupon :1? Thus it is seen that the accelerating switch coil S is connected across the armature ot the motor. The ll1'3! To the side ot the car C there is atlixed a cam 10 for operation the switches 4i, 6, 7, 8 and 9 and in the car there is a controlling switch G for operating the car. The coil of switch l connected in series with the armature ot the motor and is adapted to operate and close the Contact.

    In combination, an alternating current motor having slow and fast speed windings, a source of power for said motor, means operable while the motor is running for connecting the slow speed windings or" said motor to the source so as to dynamically brake the motor, means for disconnecting the motor from said source, and a switch having windings in circuit with the slow speed windings of the motor for'controlling the operation of said disconnecting means.

    In testimony whereof, I have signed my name to this specification. A control system for an elevator car comprising, a motor for raising and lowering the car, a source of power for the motor, a dynamic brake circuit for the motor, a switch operable as the car approaches a predetermined point to complete said circuit, a second switch operable as the car approaches still closer to said point to cause the disconnection of the motor from said source, and a third switch dependent on the current in the dynamic brake circuit for rendering the operation of the second switch ineffective.

    Thus it is seen that the accelerating switch coil S is connected across the armature ot the motor. The operation of the apparatus shown in Figure 3 is as follows: Assume that the car U is to be run from the bottom to the top terminal landings.

    In combination, an alternating current motor having slow and fast speed windings, a source of power for said motor, means operable while the motor is running for connecting the slow speed windings of said motor to the source so as to dynamically brake the motor, means for disconnecting the motor from said source, and means dependent on the current in the slow speed windings of the motor during the dynamic braking operation for controlling the operation of the disconnecting means.

    The contact on switch 0 is adapted to be closed if the voltage across the armatiu'e falls below a predetermined value: the contact on switch P is adapted to be closed it the c" at in the armature is above a predetei ed ralue: and the contact on switch Q is adapted to be closed it the current in the field is above a predetermined value. Figure shows the application ot' my ir venlion to an elevator driven by a two speed alternating current motor in the control of which the means to oilect the immediate interruption ot the power to the motor as mentioned above is dependent upon the speed of the elevator and upon the opt-ration of the electromagnet switch controlling the fast and slow speeds of the motor.
