Abstract
Abstract A universal extractor tool having first and second U-shaped members attached together for relatively slidable movement in one direction and having a resilient cushion of non-metallic material positioned between said U-shaped members for providing first and second resistive forces when said U-shaped members are moved together. A puller plate is removably attached to one of said Ushaped members and means are provided on said puller plate for engaging a module board to be extracted from a mounting frame.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
204 words
A universal extractor tool for removing an electronic module from a chassis comprising: a first U-shaped member having a crossbar and first and second parallel legs each having an elongated slot therein, a second U-shaped member having a crossbar and first and second parallel legs, said second U-shaped member being smaller in width and height than said first U-shaped member, a puller plate removably attached to said second U-shaped member and having oppositely extending ears slidably engageable one each in each said elongated slot in said first U-shaped member, a resilient cushion of non-metallic material having a top groove forming a first pair of side flanges with said top groove engaging said crossbar of said first U-shaped member and a bottom groove forming a second pair of side flanges with said bottom groove engaging said crossbar of said second U-shaped member whereby said first and second pairs of side flanges retain said resilient cushion in position between said crossbars, said resilient cushion having means for providing first and second resistive forces when said crossbar of said second U-shaped member is moved toward said crossbar of said first U-shaped member, and means on said Puller plate for attaching said puller plate to an electronic module.
Claim 2
Dependent Claim
204 words
A universal extractor tool for removing an electronic module from a chassis comprising: a first U-shaped member having a crossbar and first and second parallel legs each having an elongated slot therein, a second U-shaped member having a crossbar and first and second parallel legs, said second U-shaped member being smaller in width and height than said first U-shaped member, a puller plate removably attached to said second U-shaped member and having oppositely extending ears slidably engageable one each in each said elongated slot in said first U-shaped member, a resilient cushion of non-metallic material having a top groove forming a first pair of side flanges with said top groove engaging said crossbar of said first U-shaped member and a bottom groove forming a second pair of side flanges with said bottom groove engaging said crossbar of said second U-shaped member whereby said first and second pairs of side flanges retain said resilient cushion in position between said crossbars, said resilient cushion having means for providing first and second resistive forces when said crossbar of said second U-shaped member is moved toward said crossbar of said first U-shaped member, and means on said Puller plate for attaching said puller plate to an electronic module.
Claim 3
Dependent Claim
41 words
A universal extractor tool as set forth in claim 1 wherein said means in said resilient cushion for providing first and second resistive forces comprises a centrally located elongated hole having a width approximately one-third the width of said resilient cushion.
Claim 4
Dependent Claim
53 words
A universal extractor tool as set forth in claim 1 having first and second sleeves of non-metallic material, said first sleeve surrounding one leg of said first U-shaped member and an adjacent leg of said second U-shaped member and said second sleeve surrounding the other legs of said first and second U-shaped members.
