Vintage Mechanical Clamp Diagram - Engineering Illustration & Function Guide #134853 (License: Personal Use)

This black-and-white engineering diagram displays two configurations of a vintage mechanical clamp: one fully assembled with stacked springs and pivoting arms, and another in exploded view to reveal internal mechanics. Smaller inset drawings illustrate the clamp’s compact folded state and jaw engagement detail, emphasizing its toggle-lock principle and manual actuation. The shading and linework follow 19th- to early-20th-century technical drafting conventions.
