Abstract
Abstract An apparatus for removing a multi-contact component installed in sockets on a circuit board. The apparatus includes at least one elongated post for providing an upward force on the lower surface of the component to remove the component from the sockets. The logitudinal axis of the post is generally normal to the lower surface of the component. At least one screw is mechanically coupled to the post so that rotation of the screw causes longitudinal movement of the post.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
92 words
Apparatus for removing a multicontact component installed in sockets on a circuit board, said component having a lower surface facing said circuit board, said apparatus comprising: at least one elongated post for providing an upward force on said lower surface of said component to remove said component from said sockets, said at least one elongated post having a screw-threaded portion and at least one screw member mechanically coupled to said post so that rotation of said post causes longitudinal movement of said post toward said lower surface thereby effecting said upward force.
Claim 2
Dependent Claim
92 words
Apparatus for removing a multicontact component installed in sockets on a circuit board, said component having a lower surface facing said circuit board, said apparatus comprising: at least one elongated post for providing an upward force on said lower surface of said component to remove said component from said sockets, said at least one elongated post having a screw-threaded portion and at least one screw member mechanically coupled to said post so that rotation of said post causes longitudinal movement of said post toward said lower surface thereby effecting said upward force.
Claim 3
Dependent Claim
18 words
The apparatus of claim 1 wherein said screw member is a nut for installation on said circuit board.
Claim 4
Dependent Claim
23 words
The apparatus of claim 1 wherein said screw member is a nut for installation on a body in which said sockets are supported.
Claim 5
Dependent Claim
30 words
The apparatus of claim 3 further comprising said circuit board, wherein said circuit board has a hole aligned with said nut on said body and through which said post extends.
Claim 6
Dependent Claim
55 words
The apparatus of claim 1 wherein said screw member is a threaded member with flexible arms, said arms being capable of flexing inwardly to permit said member to pass through holes in at least one of said circuit board and body, and of moving outwardly thereafter to engage one of said circuit board and body.
Claim 7
Dependent Claim
12 words
The apparatus of claim 1 wherein there are a plurality of posts.
Claim 8
Dependent Claim
65 words
The apparatus of claim 1 further comprising a bearing plate at the longitudinally upper end of said at least one post, said bearing plate being supported on its underside by said post, and having an upper surface for contacting the lower surface of said component for distributing said upward force over the area of said lower surface which is in contact with said upper surface.
Claim 9
Dependent Claim
41 words
The apparatus of claim 6 further comprising a plate connected to the longitudinally lower end of said posts to mechanically couple said at least one screw to said posts so that rotation of said screw causes longitudinal movement of the posts.
Claim 10
Dependent Claim
18 words
The apparatus of claim 1 further comprising a handle for manual rotation of said at least one post.
Claim 11
Dependent Claim
22 words
The apparatus of claim 1 wherein the longitudinal axis of said post is generally normal to said lower surface of said component
Claim 12
Dependent Claim
114 words
The apparatus of claim 1 further comprising a plurality of posts without screw-threaded portions and further comprising a plate connected to the longitudinally lower end of said plurality of posts to mechanically couple said post with a said plurality of posts to mechanically couple said post with a screw-threaded portion to said plurality of posts so that rotation of said post with a screw-threaded portion causes longitudinal movement of the posts without screw-threaded portions and wherein the plate is positioned below the printed circuit board and the multiple contact component, said plate being coupled to said post with a screw-threaded portion so that said plate can move longitudinally along an axis of the socket.
Claim 13
Independent Claim
124 words
A method for removing a multi-contact component installed in sockets on a circuit board, said component having a lower surface facing said circuit board, said method comprising: positioning at least one elongated post beneath said multi-contact component so that upward movement of the post exerts an upward force on the lower surface of the component tending to remove the component from the sockets, said at least one post having a screw-threaded portion and mechanically coupling at least one screw member to the post so that rotation of the post causes longitudinal movement of the post toward said lower surface thereby effecting said upward force, and rotating the screw to move the post upwardly and thereby move the component out of engagement with the sockets.
Claim 14
Independent Claim
124 words
A method for removing a multi-contact component installed in sockets on a circuit board, said component having a lower surface facing said circuit board, said method comprising: positioning at least one elongated post beneath said multi-contact component so that upward movement of the post exerts an upward force on the lower surface of the component tending to remove the component from the sockets, said at least one post having a screw-threaded portion and mechanically coupling at least one screw member to the post so that rotation of the post causes longitudinal movement of the post toward said lower surface thereby effecting said upward force, and rotating the screw to move the post upwardly and thereby move the component out of engagement with the sockets.
Claim 15
Dependent Claim
66 words
The method of claim 12 further comprising positioning a bearing plate at the longitudinally upper end of said at least one post, said bearing plate being supported on its underside by said post, and having an upper surface for contacting the lower surface of said component for distributing said upward force over the area of said lower surface which is in contact with said upper surface.
