Abstract
Abstract A tool for handling integrated circuits to facilitate their installation on and extraction from circuit boards. A pair of spaced apart levers are pivotal about integral hinges in a manner to engage opposite ends of the integrated circuit. Each lever carries a pair of lugs between which the ends of the integrated circuit are gripped. The opposite end of the tool is constructed similarly although with a pair of levers that are closer together in order to handle a smaller integrated circuit.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
158 words
A tool for assisting in the insertion of an integrated circuit on a circuit board and the extraction of same from the circuit board, said tool comprising: a frame; a pair of spaced apart levers for engaging and releasing the integrated circuit each lever having a gripping portion and a movement imparting portion; gripping means on each lever for gripping opposite ends of the integrated circuit to facilitate insertion and extraction of same, said gripping means being located at the gripping portion of each lever; and a hinge connection associated with each lever, said hinge connection being operable to couple its associated lever in spaced apart relationship with the frame such that the gripping portion and the movement imparting portion of the lever extend outward from said hinge connection in opposite directions and to allow its associated lever to pivot about the hinge connection in response to a force applied to the movement imparting portion of the lever.
Claim 2
Dependent Claim
158 words
A tool for assisting in the insertion of an integrated circuit on a circuit board and the extraction of same from the circuit board, said tool comprising: a frame; a pair of spaced apart levers for engaging and releasing the integrated circuit each lever having a gripping portion and a movement imparting portion; gripping means on each lever for gripping opposite ends of the integrated circuit to facilitate insertion and extraction of same, said gripping means being located at the gripping portion of each lever; and a hinge connection associated with each lever, said hinge connection being operable to couple its associated lever in spaced apart relationship with the frame such that the gripping portion and the movement imparting portion of the lever extend outward from said hinge connection in opposite directions and to allow its associated lever to pivot about the hinge connection in response to a force applied to the movement imparting portion of the lever.
Claim 3
Dependent Claim
39 words
A tool as set forth in claim 1, wherein said gripping means comprises a pair of spaced apart lugs carried on each lever to engage the top and bottom surfaces of the integrated circuit at the opposite ends thereof.
Claim 4
Dependent Claim
34 words
A tool as set forth in claim 2, including a smoothly curved surface on one lug in each pair to facilitate release of said one lug from the bottom surface of the integrated circuit.
Claim 5
Dependent Claim
49 words
A tool as set forth in claim 1, including a support member on said frame extending substantially between said levers at a location to engage the upper surface of the integrated circuit substantially continuously along the length thereof when said levers are applied to opposite ends of the circuit.
Claim 6
Dependent Claim
22 words
A tool as set forth in claim 1, wherein said hinge connections are integral with the respective levers and with said frame.
Claim 7
Dependent Claim
32 words
A tool as set forth in claim 1, wherein said frame includes a cross member substantially spanning same, said hinge connections coupling the respective levers with opposite ends of said cross member.
Claim 8
Dependent Claim
22 words
A tool as set forth in claim 6, wherein said hinge connections are integral with said cross member and with said levers.
Claim 9
Dependent Claim
55 words
A tool as set forth in claim 6, including a plate member connected with said cross member and with each hinge connection, said plate member having an edge positioned to engage the upper surface of the integrated circuit substantially continuously along the length thereof when said levers are applied to opposite ends of the circuit.
Claim 10
Dependent Claim
179 words
A tool as set forth in claim 1, including: a second pair of spaced apart levers each lever having a gripping portion and a movement imparting portion; gripping means on each lever in said second pair for gripping opposite ends of integrated circuits to facilitate insertion and extraction of same, said gripping means being located at the gripping portion of each lever; and a hinge connection associated with each lever in said second pair to couple the levers in said second pair to said frame such that the gripping portions of levers in the second pair project in a generally opposite direction from the gripping portions of the levers in the first mentioned pair, said hinge connection being operable to couple its associated lever in spaced apart relationship with the frame such that the gripping portion and the movement imparting portion of the lever extend outward from said hinge connection in opposite directions and to allow its associated lever to pivot about the hinge connection in response to a force applied to the movement imparting portion of the lever.
