Abstract
Toggle-lever construction especially for a vise or similar holdng means. There is provided a toggle-lever construction in which one end thereof is backed against a suitable anchor device and the other end thereof bears against movable means such as the jaw of a vise. A relatively light force applied laterally of the toggle will produce a large force longitudinally thereof. In one embodiment the lateral force is applied by a longitudinally moving tapered screw. Wear on the toggle is minimized by providing rounded ends having substantially only a line contact between the components of the toggle with respect to each other and between the components of the toggle and the means engaging the respective free ends thereof.
