Abstract
Abstract A device for removing printed circuit cards from a container, such as a computer control box, comprising a tool having an end mechanism for engaging an adapter provided on the end of each printed circuit card. The tool firmly interlocks with the card adapter while simultaneously unlatching a spring loaded latch that secures the card in the container. Use of the tool permits removal, handling and replacement of printed circuit cards with the use of one hand.

Claim 1
Independent Claim
122 words
A tool for engaging and handling an article bearing a projecting, slotted flange and bearing a latch for latching said article in a container comprising: a. a flange receiving element having a channel therein adapted for receiving the projecting flange of said article; b. an interlocking portion adapted to interlock with the projecting flange of said article rotatably mounted on said tool and disposed along said flange receiving element; c. said interlocking portion having a length exceeding the width of said channel of said flange receiving element; d. means for turning said interlocking portion either across said channel or longitudinally of said channel; e. said interlocking portion being clear of said channel when said interlocking portion is turned longitudinally of said channel.
Claim 2
Dependent Claim
122 words
A tool for engaging and handling an article bearing a projecting, slotted flange and bearing a latch for latching said article in a container comprising: a. a flange receiving element having a channel therein adapted for receiving the projecting flange of said article; b. an interlocking portion adapted to interlock with the projecting flange of said article rotatably mounted on said tool and disposed along said flange receiving element; c. said interlocking portion having a length exceeding the width of said channel of said flange receiving element; d. means for turning said interlocking portion either across said channel or longitudinally of said channel; e. said interlocking portion being clear of said channel when said interlocking portion is turned longitudinally of said channel.
Claim 3
Dependent Claim
60 words
