  • Control device having improved terminal means and method of making the same
    Patent number: 4021094
    Abstract: A control device having a housing provided with a terminal that has a threaded screw member with its shank threadedly carried thereby for lead attachment thereto between an enlarged head of the screw member and the terminal. A resilient retainer clip is disposed between the head of the screw member and the terminal, the clip initially being under compression between the head of the screw member and the terminal to tend to hold the screw member in its threaded relation with the terminal. A lead is subsequently disposed between the clip and the terminal, the clip thereafter being disposed in a deformed condition against the lead to hold the lead to the terminal.
    Type: Grant

  • Control device having locking selector means
    Patent number: 3965755
    Abstract: A control device having a housing provided with a movable actuator and a rotatable selector shaft for positioning the actuator in relation to the rotational position of the shaft. An actuator driver is carried by the shaft and is operatively interconnected to the actuator to drive the same upon rotation of the driver by the shaft, the shaft and driver being axially movable relative to the actuator. The housing has a latching part cooperable with a latching part of the shaft when the shaft is in a certain rotational and axial position relative to the housing whereby the shaft cannot be rotated relative to the housing until the shaft is axially moved from that certain axial position thereof to another axial position thereof to clear the latching part of the shaft from the latching part of the housing and thereby unlock the selector shaft.

  • Electrical terminal means
    Patent number: 3944315
    Abstract: A control device having a housing provided with a terminal that has a threaded screw member with its shank threadedly carried thereby for lead attachment thereto between an enlarged head of the screw member and the terminal. A resilient retainer clip is disposed between the head of the screw member and the terminal, the clip initially being under compression between the head of the screw member and the terminal to tend to hold the screw member in its threaded relation with the terminal. A lead is subsequently disposed between the clip and the terminal, the clip thereafter being disposed in a deformed condition against the lead to hold the lead to the terminal. The clip has a plurality of slots in the deformable portion thereof to render the same more deformable.
