Apparatus for connecting a switch operator to a switch

Apparatus for locking together for conjoint coaxial rotation about a common axis a pair of rotatable members, it being necessary to lock the members together after they are first moved to predetermined, angular positions about the axis whereat their exact relative angular orientation is randomly unpredictable;

• the apparatus comprising:
• an elongated slot through one member;
• a hole through the other member, the hole having a size and location so as to generally overlie and encompass the slot when the members are in the predetermined positions;
• a tapered disk having an off-center aperture, the disk being insertable into the hole and rotatable therein until the aperture is visually observed to overlie and be aligned with the slot;
• and
• a connecting means insertable through the aligned aperture and slot to lock the members together and to jam the disk into the hole to prevent rotation therein.

Apparatus for locking a first movable member to a second movable member so that the members move together, the members being locked together while they are in independent, predetermined positions whereat their relative orientation is unpredictable and random;

• the apparatus comprising:
• a slot formed through the second member;
• a hold formed through the first member so as to generally overlie and encompass the slot when the members are in their predetermined positions;
• a tapered disk having an off-center aperture therethrough, the disk being insertable into the hole and rotatable until the aperture is visually observed to overlie and be aligned with the slot;
• and
• connecting means insertable through the aligned aperture and slot for pulling the first member and the disk toward the second member to lock the members together so that they move together and to jam the disk into the hold to prevent rotation therein.

Apparatus for locking a first member rotated by a switch operator to a second member which rotates to operate a switch so that the members rotate coaxially together, the members being locked together while they, the operator, and the switch are in independent, predetermined positions whereat the relative angular orientation of the members about a common axis is unpredictable and random;

• the apparatus comprising:
• an elongated slot formed through the second member;
• a hole formed through the first member so as to generally overlie and encompass the slot when the members are in their predetermined positions;
• a tapered disk having an off-center aperture therethrough, the disk being insertable into the hole and rotatable until the aperture is visually observed to overlie and be aligned with the slot;
• and
• connecting means insertable through the aligned aperture and slot for pulling the first member and the disk toward the second member to lock the members together so that they are coaxially rotatable together and to jam the disk into the hole to prevent rotation therein.
