Abstract: Suspension Eyewear consists of a pair of ophthalmic lenses attached to a metal centerpiece in the manner of conventional rimless eyeglasses. Instead of hinges and temples there are two suspension lines attached to each lens near the outer edges, and at points sufficiently separated to provide stability. The plane of the front assembly to the face is controlled by adjusting the length of these lines in a device positioned just in front of and about midway the ear. A wirebound springwire attached to the adjusting device extends over and behind each ear to below the mastoid. These spring earwires will return the front assembly to proper alignment when it is lightly pushed or pulled, in any direction, and released.

Abstract: The spectacle frame includes a frontal lens support incorporating a nose bridge, a pair of temples, and hinges connecting each temple to an outer end of the lens support. A blind bore is formed in either the lens support or the temple at at least one outer end of the lens support. An adjustment mechanism, including an internally threaded sleeve and an externally threaded adjusting rotor member, is inserted in each bore. The adjusting rotor member has an outer end engaging the other of the lens support and the temple. The adjusting mechanism is formed with a notched or knurled operating head particularly configured for operative association with assembling tools.
