Abstract
Abstract A device to facilitate the placing of lockbolt type fasteners by means of apparatus which swages a lockbolt collar onto the grooved stem of a lockbolt pin has a resilient body portion which frictionally grips the swaging apparatus so as to mount the device on the apparatus, and resilient arms which frictionally grip the collar to be swaged and hold it in appropriate relationship to the swaging apparatus to permit insertion of the stem through the collar and the swaging anvil of the swaging apparatus. The device may co-operate with a movable part of the swaging apparatus to produce movement of the arms to release the collar and to avoid interference of the device between the swaging apparatus and the work.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
88 words
A collar-carrying device comprising a body portion for attaching the device to lockbolt-swaging apparatus of the type defined, and a plurality of arms extending forwardly of the body for holding a collar for a lockbolt in front of an annular anvil of the swaging apparatus in appropriate relationship to permit insertion of a lockbolt stem through the collar and the annular anvil, said arms providing inclined surfaces for translating relative axial movement of the device and a part of the swaging apparatus into transverse movement of the arms.
Claim 2
Dependent Claim
88 words
A collar-carrying device comprising a body portion for attaching the device to lockbolt-swaging apparatus of the type defined, and a plurality of arms extending forwardly of the body for holding a collar for a lockbolt in front of an annular anvil of the swaging apparatus in appropriate relationship to permit insertion of a lockbolt stem through the collar and the annular anvil, said arms providing inclined surfaces for translating relative axial movement of the device and a part of the swaging apparatus into transverse movement of the arms.
Claim 3
Dependent Claim
111 words
Lockbolt-swaging apparatus of the kind defined comprising an annular anvil for swaging a lockbolt collar to a stem of a lockbolt pin, and retractable stem gripping means including a collar-carrying device comprising a body portion for attaching the device to lockbolt-swaging apparatus, and a plurality of arms extending forwardly of the body for holding a collar for a lockbolt in front on the anvil of the swaging apparatus in appropriate relationship to permit insertion of a lockbolt stem through the collar and the annular anvil, said arms providing inclined surfaces for translating relative axial movement of the device and a part of the swaging apparatus into transverse movement of the arms.
Claim 4
Dependent Claim
111 words
Lockbolt-swaging apparatus of the kind defined comprising an annular anvil for swaging a lockbolt collar to a stem of a lockbolt pin, and retractable stem gripping means including a collar-carrying device comprising a body portion for attaching the device to lockbolt-swaging apparatus, and a plurality of arms extending forwardly of the body for holding a collar for a lockbolt in front on the anvil of the swaging apparatus in appropriate relationship to permit insertion of a lockbolt stem through the collar and the annular anvil, said arms providing inclined surfaces for translating relative axial movement of the device and a part of the swaging apparatus into transverse movement of the arms.
Claim 5
Dependent Claim
53 words
Lockbolt-swaging apparatus according to claim 2 wherein the collar-carrying device is axially movable relative to the annular anvil, the arrangement being such that, relative movement between the collar-carrying device and the anvil during swaging of a lockbolt collar causes transverse movement of the arms in a direction to release the collaR being swaged.
Claim 6
Dependent Claim
11 words
A device according to claim 1, wherein the arms are resilient.
Claim 7
Dependent Claim
38 words
A device according to claim 1, wherein the arms each comprise a first portion adjoining the body portion of the device, and a free end portion, said free end portions being directed inwardly and generally towards each other.
Claim 8
Dependent Claim
18 words
A device according to claim 5, wherein the said first portions of the arms provide said inclined surfaces.
Claim 9
Dependent Claim
18 words
A device according to claim 1, wherein the body portion comprises means for resiliently gripping the swaging apparatus.
Claim 10
Independent Claim
82 words
A device adapted to be mounted on lockbolt-swaging apparatus of the type defined and to hold a collar for a lockbolt in appropriate relationship to the annular anvil of the swaging apparatus to permit the lockbolt stem to be inserted axially through the collar and the annular anvil, said device comprising of a resilient longitudinally split tubular body portion for gripping the swaging apparatus and, integral with the body portion, resilient opposing arms which extend from one end of the body portion.
Claim 11
Independent Claim
82 words
A device adapted to be mounted on lockbolt-swaging apparatus of the type defined and to hold a collar for a lockbolt in appropriate relationship to the annular anvil of the swaging apparatus to permit the lockbolt stem to be inserted axially through the collar and the annular anvil, said device comprising of a resilient longitudinally split tubular body portion for gripping the swaging apparatus and, integral with the body portion, resilient opposing arms which extend from one end of the body portion.
Claim 12
Dependent Claim
61 words
A device according to claim 8, wherein each arm comprises a first portion adjoining said body portion and a free end portion remote from the body portion, said free end portions being directed inwardly and generally towards each other and terminating at points lying on a circle, whereby said free end portions may resiliently grip the periphery of the lockbolt collar.
Claim 13
Dependent Claim
56 words
A device according to claim 9, wherein said first portions of the arms are inwardly inclined, thereby to co-operate with the anvil of a swaging apparatus when said anvil moves forwardly relative to the device, to force said arms resiliently outwards and so to release a collar engaged between said free end portions of the arms.
Claim 14
Dependent Claim
12 words
Apparatus according to claim 2, wherein the arms resiliently grip the collar.
Claim 15
Dependent Claim
43 words
Lockbolt-swaging apparatus according to claim 2, wherein return relative movement of the anvil and the retractable stem gripping means produces return movement of the collar-carrying device relative to the anvil thereby to restore the collar-carrying device to a condition for retaining a collar.
