Abstract
Abstract A co-axial lead straightening apparatus has a pair of conically shaped shoes selectively positioned adjacent to a pair of rotatably mounted frustum shaped drums. At a discharge end, the distance between each shoe and its respective drum is held constant along the length of the drum and at a receiving end, the distance between each shoe and its respective drum increases from the base of the drum to the top of the drum. Bent leads of coaxial lead components moved between the drums and shoes at the receiving end are rotated through decreasing distances between the drums and shoes as the component is displaced from the receiving end to the discharge end to straighten the leads.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
173 words
An apparatus for straightening a wire comprising: a rotatably mounted frustum shaped drum having a base and a top; a conically shaped shoe having a base and a top mounted about said drum with the top of said shoe adjacent the base of said drum and the base of said shoe adjacent the top of said drum, the distance between the top of said shoe and the base of said drum being sufficient to accommodate the wire therebetween while frictionally engaging the wire, said shoe being spaced equidistant from said drum at a discharge end so that at a receiving end the distance between said drum and said shoe increases from the base to the top of said drum; and means for rotating said drum so that a wire frictionally engaged between the top of said shoe and the base of said drum is rotated and displaced through decreasing distances between said shoe and said drum from the receiving end towards the discharge end thereby working and forming the wire to straighten same.
Claim 2
Independent Claim
173 words

Claim 3
Dependent Claim
51 words
The apparatus as set forth in claim 1, further including: means for biasing said shoe toward said drum to accommodate the wire between the top of said shoe and the base of said drum while frictionally engaging the wire between the top of said shoe and the base of said drum.
Claim 4
Dependent Claim
225 words
Apparatus for straightening co-axial leads of electrical components comprising: a pair of rotatably mounted frustum shaped drums each having a contact surface extending between a base and a top, the base of each of said drums being opposed and adjacent to one another; a conically shaped shoe having a concave contact surface extending between a base and a top mounted about each of said drums with the top of each of said shoes spaced from the base of each of said drums and the base of each of said shoes spaced from the top of said drum, the contact surface being spaced equidistant at the top of the shoe and the base of the drum to accommodate the leads of the electrical component therebetween while frictionally engaging the leads, said shoes being spaced equidistant from the contact surface of each of said drums at a discharge end so that at a receiving end the distance between the contact surfaces increases from the base to the top of said drum; and means for rotating said drums so that leads frictionally engaged between each one of the tops of said shoes and each one of the bases of said drums is rotated through decreasing distances between said contact surfaces as the component is displaced toward the discharge end thereby working and forming the leads to straighten same.
