A carrier is disclosed for supporting an optical blank in the chuck of a lathe, for machining the optical blank into a lens. The carrier has a substantially cylindrical body formed of a machinable material. The cylindrical body has an opening at a first end thereof through which an optical blank can be inserted, and a retaining portion for securing such optical blank in place. In a preferred embodiment, the retaining portion is an annular shoulder extending inwardly at a second end of the cylindrical body.

Optical blank carrier for lathing lenses and process therefor

A car top carrier assembly which is characterized by a light weight carrier container with an overall rectangular solid configuration, having its edges and corners radiused between all intersections of planar surfaces. The container has no internal frame, but rather the frame itself is comprised of a horizontal deck member, vertical corner support members, and horizontal edge supports, with the planar top and side portions being simple rectangular pieces of sheet material which are flangedly connected onto the corner and edge supports to define the overall container. The car top carrier is mounted upon a car top through a pair of contracting support tubes, which exert a contractive force proximate the edges of a car top, while inherently locating the superposed container in a fixed position as a consequence of the engaging step. The present invention thereby defines a particularly strong and light weight car top carrier, one which is significantly characterized by a container which requires no separate internal framing members, since the load-bearing frame is comprised of aluminum extrusions which themselves define the radiused corners and edges of the container.

Car top carrier assembly

An adjustable car top carrier support which is operable for use on a gutterless car top including ledges at its opposite sides. In one embodiment, the carrier support is significantly characterized by having a clutch upon a crankshaft, for limiting the amount of the contractive force which may be applied by the carrier upon the car top. The adjustable car top carrier is further characterized by car top engaging combination which includes a pivotable foot pad, together with a ledge hook for ensuring that the contractive forces of the carrier are inserted into the vicinity of the opposite ledges of a car top. The present invention is particularly useful on a gutterless car top, though may be employed upon any form of a vehicle roof member that conventionally includes a ledge on opposite sides thereof.
