  • Tamperproof locking and latching mechanism for rotatable controls
    Patent number: 4126023
    Abstract: A latching and locking mechanism for a rotatable control of the type having a stem journaled in a body and rotatable about an axis in a boss on the body. The stem has a protuberance for engagement with a handle. The handle comprises a boss-engaging end portion, a stem-engaging portion, a slider-riding portion, and a grip end portion. The slider-riding portion has a slider with a tang extending therefrom and means for securing a lock to restrict movement of the slider. The boss has surfaces located to correspond to predetermined positions of the stem. These surfaces are engageable by the tang which, when so engaged, restrains the handle from rotation and prevents removal of the handle from the stem.
