Abstract
Abstract An extracting tool for removing an electronic plug-in module from a chassisssembly applies, by mechanical advantage, a large extracting force to a module. An extractor plate engageable with a plug-in module is slidably connected to a frame and a rotatable cam is provided for linearly moving the extractor plate. A handle integral with the cam is used for rotating the cam, and a cam surface on the handle is used to return the extractor plate to a starting position when the handle is moved in a reverse direction.

Claim 1
Independent Claim
102 words
An extractor tool for removing an electronic plug-in module from a chassis comprising, a frame, an extractor plate slidably attached to said frame, a cam pin attached to said extractor plate, first cam means rotatably attached to said frame and engageable with said cam pin for linearly moving said extractor plate in a first direction, a handle for rotating said first cam means, first and second pins on said extractor plate for engaging an electronic plug-in module, and second cam means on said handle engageable with said cam pin for moving said extractor plate in a direction opposite to said first direction.
Claim 2
Dependent Claim
102 words
An extractor tool for removing an electronic plug-in module from a chassis comprising, a frame, an extractor plate slidably attached to said frame, a cam pin attached to said extractor plate, first cam means rotatably attached to said frame and engageable with said cam pin for linearly moving said extractor plate in a first direction, a handle for rotating said first cam means, first and second pins on said extractor plate for engaging an electronic plug-in module, and second cam means on said handle engageable with said cam pin for moving said extractor plate in a direction opposite to said first direction.
Claim 3
Dependent Claim
172 words
An extractor tool for removing an electronic plug-in module from a chassis, said tool comprising: a frame having a linear groove; an extractor plate having pins for engaging openings in a module, said plate also having a tongue slidably engaged in said groove whereby said plate is guide for linear movement relative to said frame, and said tongue having an elongated slot therein; a cam pin attached to said tongue of said extractor plate; pivot means extending from said frame through said slot in said tongue; first cam means rotatably attached to said frame by said pivot means with said tongue disposed between said first cam means and said frame, said first cam means being engageable with said cam pin; a handle for rotating said first cam means so as to act against said cam pin and effect said linear movement of said extractor plate in one direction; and second cam means on said handle engageable with said cam pin for effecting linear movement of said extractor plate in the opposite direction.
Claim 4
Dependent Claim
