Carrier handle

Claim 1

A device attachable to an end panel of a wafer carrier for manipulating the carrier and retaining wafers at the open side of the carrier, comprising first and second opposing clamp jaws for attaching to opposite edges of the carrier end panel, an elongate articulated frame having the first jaw mounted thereon and including a guiding foot with an elongate bottom, a mounting plate affixed to the second jaw and lying against the bottom of the guide foot for movement therealong and maintaining the orientation of the second jaw with respect to the first jaw, an operating means on the frame connected with the mounting plate for moving the plate and second jaw along the guide foot toward and away from the first jaw, and a retaining rod connected to the frame adjacent the first jaw and extending transversely from the first jaw to traverse the open side of the carrier and retain the wafers therein.

Claim 2

A device attachable to an end panel of a wafer carrier for manipulating the carrier and retaining wafers at the open side of the carrier, comprising first and second opposing clamp jaws for attaching to opposite edges of the carrier end panel, an elongate articulated frame having the first jaw mounted thereon and including a guiding foot with an elongate bottom, a mounting plate affixed to the second jaw and lying against the bottom of the guide foot for movement therealong and maintaining the orientation of the second jaw with respect to the first jaw, an operating means on the frame connected with the mounting plate for moving the plate and second jaw along the guide foot toward and away from the first jaw, and a retaining rod connected to the frame adjacent the first jaw and extending transversely from the first jaw to traverse the open side of the carrier and retain the wafers therein.

Claim 3

A device attachable to an end panel of a wafer carrier for manipulating the carrier and retaining wafers at the open side of the carrier, comprising elongate first and second opposing clamp jaws each having a panel receiving recess for confronting and engaging opposite edges of the carrier end panel and a mounting plate for confronting and engaging the panel to maintain a predetermined orientation between the jaws and the carrier, an articulated elongate frame interconnecting the jaws, the first jaw being rigid with respect to the frame, the frame having a grip bar adapted to be manually gripped, a guide foot with an elongate bottom for movement of the mounting plate of the second jaw therealong and maintaining the orientation of the second jaw with respect to the first jaw, and a mechanism for producing substantially linear movement of the second jaw toward and away from the first jaw along the bottom of the guide foot including a spring for biasing the second jaw away from the first jaw into a open position and an operating lever connected with the mounting plate of the second jaw operable for producing the movement of the second jaw toward the first jaw into a closed position, the lever extending along the grip bar to be simultaneously gripped by a person's hand, the grip bar having a hollow portion U-shaped in cross section for receiving and recessing the operating lever, and a pair of retaining rods of inert plastic highly resistant to corrosive effects of active chemicals parallel to and spaced from each other attached to the mounting plate of the first jaw, the rods being rigid with respect to the grip bar and extending transversely from the first jaw to traverse the open side of the carrier and retain the wafers therein.

Claim 4

A device attachable to an end panel of a wafer carrier for manipulating the carrier and retaining wafers at the open side of the carrier, comprising elongate first and second opposing clamp jaws each having a panel receiving recess for confronting and engaging opposite edges of the carrier end panel and a mounting plate for confronting and engaging the panel to maintain a predetermined orientation between the jaws and the carrier, an articulated elongate frame interconnecting the jaws, the first jaw being rigid with respect to the frame, the frame having a grip bar adapted to be manually gripped, a guide foot with an elongate bottom for movement of the mounting plate of the second jaw therealong and maintaining the orientation of the second jaw with respect to the first jaw, and a mechanism for producing substantially linear movement of the second jaw toward and away from the first jaw along the bottom of the guide foot including a spring for biasing the second jaw away from the first jaw into a open position and an operating lever connected with the mounting plate of the second jaw operable for producing the movement of the second jaw toward the first jaw into a closed position, the lever extending along the grip bar to be simultaneously gripped by a person's hand, the grip bar having a hollow portion U-shaped in cross section for receiving and recessing the operating lever, and a pair of retaining rods of inert plastic highly resistant to corrosive effects of active chemicals parallel to and spaced from each other attached to the mounting plate of the first jaw, the rods being rigid with respect to the grip bar and extending transversely from the first jaw to traverse the open side of the carrier and retain the wafers therein.
