Abstract
Abstract A wire-forming mechanism, for instance in a machine for forming and applying oppositely extending leads of components, comprises an inside former adapted in response to forming operation of an outside former, suitably to yield whereby leads of different diameters may be accommodated and precisely formed and advanced under control for terminal insertion. The invention has particular advantage in enabling a single inserting machine to attain reliable mounting in a printed circuit board of a pretaped series of components having differently sized bodies as well as differently sized leads.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
114 words
In a machine for forming the leads of coaxial lead-type components, which leads may respectively differ in diameter over a dimensional range, a reciprocable outside former having a guide groove the wall of which is engageable with an outer side of each lead to be formed, and a bodily movable inside former operative in one position to engage the inner side of said lead and cooperative with the outside former to bend and direct the lead away from the axis of the component, said inside former having a lead engaging portion yieldable laterally in response to inward pressure transmitted through the lead by the grooved wall of the outside former acting on said lead.
Claim 2
Dependent Claim
114 words
In a machine for forming the leads of coaxial lead-type components, which leads may respectively differ in diameter over a dimensional range, a reciprocable outside former having a guide groove the wall of which is engageable with an outer side of each lead to be formed, and a bodily movable inside former operative in one position to engage the inner side of said lead and cooperative with the outside former to bend and direct the lead away from the axis of the component, said inside former having a lead engaging portion yieldable laterally in response to inward pressure transmitted through the lead by the grooved wall of the outside former acting on said lead.
Claim 3
Dependent Claim
39 words
A machine as set forth in claim 1 wherein said inside former has a pair of laterally opposed, inwardly yieldable portions whereby the diameters of both leads of a coaxial lead-type component are similarly accommodated during its lead formation.
Claim 4
Dependent Claim
23 words
A machine as set forth in claim 2 wherein said yieldability of inside former portions is permitted by a slot extending centrally therebetween.
Claim 5
Dependent Claim
112 words
In a machine for mounting on a circuit board the presequenced components of a series having different sizes and/or spaces of component bodies and coaxial leads, said machine being of the type having a reciprocable inserter and outside formers operative at opposite sides of the inserter to bend and guide the leads of each component prior to their insertion at a selected locality of the board, the improvement which consists in providing a pivotal inside former for supporting each component by its oppositely extending leads during their bending by the outside formers, the inside former having spaced lead-engaging portions laterally yieldable inwardly to accommodate the leads bent thereover by the outside formers.
Claim 6
Dependent Claim
112 words
In a machine for mounting on a circuit board the presequenced components of a series having different sizes and/or spaces of component bodies and coaxial leads, said machine being of the type having a reciprocable inserter and outside formers operative at opposite sides of the inserter to bend and guide the leads of each component prior to their insertion at a selected locality of the board, the improvement which consists in providing a pivotal inside former for supporting each component by its oppositely extending leads during their bending by the outside formers, the inside former having spaced lead-engaging portions laterally yieldable inwardly to accommodate the leads bent thereover by the outside formers.
Claim 7
Dependent Claim
88 words
For use in a machine for bending and inserting the leads of different coaxial lead-type components, an inside former having spaced portions projecting in generally parallel relation and movable between a pair of reciprocable outside formers and to and from an operating position in which said portions support a component the leads of which are to be forMed for insertion, said portions being adapted to be yieldingly displaced toward one another on engaging the inner sides of the leads as they are wiped thereover by the outside formers.
Claim 8
Dependent Claim
88 words
For use in a machine for bending and inserting the leads of different coaxial lead-type components, an inside former having spaced portions projecting in generally parallel relation and movable between a pair of reciprocable outside formers and to and from an operating position in which said portions support a component the leads of which are to be forMed for insertion, said portions being adapted to be yieldingly displaced toward one another on engaging the inner sides of the leads as they are wiped thereover by the outside formers.
