Abstract

Abstract An extracting tool for removing a lug from an electronic part includes a pair of handle members, a gripping member and a ram, with the handle members being so related to the gripping member that on squeezing of the handles, jaws of the gripping member and of one of the handle members grip the lug of a condenser and on further squeezing of the handles a lever joined to the other of the handles moves the ram, which is mounted adjacent to one of the jaws, against the condenser, thereby causing relative motion of the condenser and the lug and extracting the lug from the condenser. Also described is a method for replacing an electrolytic can type condenser by detaching the lugs therefrom without detaching the electrical connections to the lugs and then soldering the lugs of a replacement condenser to said connected lugs.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 195 words
An extracting tool for removing a lug from an electronic part which comprises a pair of handle members, one of which, a gripping handle member, has a handle portion at one end thereof and a gripping jaw portion at the other end thereof and the other of which, a ram actuating handle member, has a handle portion at one end thereof and includes at the other end thereof means for actuating a ram, a gripping member separately pivotally connected to the handle members and having a gripping jaw portion at an end thereof, means for transmitting force between the gripping member and the handle portion of the ram actuating handle member and a ram positioned adjacent to one of the jaws to be moved substantially transversely to the direction of jaw movement of the ram actuating means as the handles are squeezed to be moved closer together after gripping of the lug, so that when the handles are squeezed together the jaws of the gripping member and the gripping handle member are brought together to grip the lug of the electronic part and the ram presses against the electronic part to pull the lug therefrom.
Claim 2
Dependent Claim 195 words
An extracting tool for removing a lug from an electronic part which comprises a pair of handle members, one of which, a gripping handle member, has a handle portion at one end thereof and a gripping jaw portion at the other end thereof and the other of which, a ram actuating handle member, has a handle portion at one end thereof and includes at the other end thereof means for actuating a ram, a gripping member separately pivotally connected to the handle members and having a gripping jaw portion at an end thereof, means for transmitting force between the gripping member and the handle portion of the ram actuating handle member and a ram positioned adjacent to one of the jaws to be moved substantially transversely to the direction of jaw movement of the ram actuating means as the handles are squeezed to be moved closer together after gripping of the lug, so that when the handles are squeezed together the jaws of the gripping member and the gripping handle member are brought together to grip the lug of the electronic part and the ram presses against the electronic part to pull the lug therefrom.
Claim 3
Dependent Claim 65 words
An extracting tool according to claim 1, suitable for removing from a condenser a lug to which other electronic components are attached, wherein the gripping handle member and gripping member are pivoted together, the ram actuating handle member and gripping member are pivoted together and the force transmitting means between the gripping handle and handle portion of the ram actuating handle member is a spring.
Claim 4
Dependent Claim 133 words
An extracting tool according to claim 1 wherein the ram is located alongside the gripping jaw portion of the gripping member, the ram actuating means is a lever portion of the ram actuating handle member at an end thereof opposite the handle end, the ram is maintained in normally retracted position by spring means, the jaws are maintained apart by spring means between the gripping handle member and the gripping member and the strength of the spring between the gripping member and the ram actuating handle member is greater than that of the spring between the gripping member and the gripping handle member so that when the handles are squeezed together the gripping jaws close on the lug, after which the ram is moved against the electronic part to remove the lug therefrom.
Claim 5
Dependent Claim 59 words
An extracting tool according to claim 3 wherein the jaws include teeth to grip the lug with sufficient force to hold it while the ram is pressed against the electronic part and moves with respect to the lug and the ram contacts the electronic part adjacent to the lug and to a side of it and the holding teeth.
Claim 6
Dependent Claim 119 words
An extracting tool according to claim 4 which includes a stop on the gripping member to limit the backward movement of the lever in a direction away from that in which the ram is pressed against the condenser and thereby also to limit the opening of the ram actuating handle member with respect to the gripping member, the ram is limited in backward motion by contact with the lever which is so limited and the opening of the gripping handle member with respect to the gripping member is limited by contact of said gripping handle member with the lever member, so that in relaxed position the extracting tool has the jaws thereof open with the ram in retracted position.
Claim 7
Dependent Claim 100 words
An extracting tool according to claim 5 wherein the ram includes a ram head, a ram rod and a ram anvil, with the ram rod being guided in its movement through an opening in the gripping member near the gripping jaw portion thereof, the gripping member has such an opening in the gripping jaw portion thereof and the lever portion of the ram actuating handle member encloses the gripping member and gripping handle member and has a connecting portion thereon which contacts the ram anvil to press the ram forward against the condenser as the tool handles are squeezed together.
