Abstract
Abstract A machine for braiding wire, yarn or other filaments around a common axis, comprising a first plurality of wire bobbins in an annular array which dispense yarn to the central axis and which array moves in one direction about the axis and a second plurality of wire bobbins in a radially more inward annular array, and each of which dispenses wire to a wire guide that delivers wire to the central axis; the second bobbins and the wire guides move together in the opposite direction around the first bobbins; each wire guide selectively shifts between a position radially outwardly of the first wire bobbins and radially inwardly of the first wire bobbins; the radial shifting motion of the guide means is between alternate first wire bobbins; means for radially shifting the wire guides to coordinate their radial movement with the relative movements of the first wire bobbins.

Claim 1
Independent Claim
421 words
A machine for braiding wire, filaments or the like, comprising: a central core at a central axis on which said core the wire is braided; a first array of first bobbins, each for carrying wire to be braided; first moving means for supporting and for moving said first bobbins annularly around said axis in a first direction; a second array of second bobbins each for carrying wire to be braided; a respective wire guide means for each said second bobbin; the wire from each said second bobbin being guided by its said wire guide means; second moving means for supporting and for moving said guide means annularly around said axis in a second direction opposite said first direction; cam means for shifting all said guide means radially of said axis; said cam means being mounted to and being rotatable with said first bobbins; cam follower means on at least some of said guide means, said cam follower means being in engagement with said cam means for being shifted by said cam means; each said cam follower means being so connected with its said guide means that shifting of said cam follower means in a third direction shifts said guide means radially inwardly of said axis and shifting of said cam follower means in a fourth direction opposite said third direction shifts said guide means radially outwardly of said axis; said cam means being shaped so as to cause each said cam follower means to cause its said guide means to shift radially inwardly of all said first bobbins, thereby enabling said guide means to pass by said first bobbins radially inwardly thereof and to cause each said guide means to shift radially outwardly of all said first bobbins, thereby enabling said guide means to pass by said first bobbins radially outwardly thereof; said cam means comprising at least one cam follower guide pathway having first cam follower shift sections which shift said cam followers in said third direction, first cam follower travel sections over which said cam followers travel after they have moved in said third direction, second cam follower shift sections which shift said cam followers in said fourth direction and second cam follower travel sections over which said cam followers travel after they have moved in said fourth direction; said cam follower first and second shift sections being located on said cam means so as to radially shift said guide means through the space between neighboring said first bobbins without engagement between said first bobbins and said guide means.
Claim 2
Dependent Claim
421 words
A machine for braiding wire, filaments or the like, comprising: a central core at a central axis on which said core the wire is braided; a first array of first bobbins, each for carrying wire to be braided; first moving means for supporting and for moving said first bobbins annularly around said axis in a first direction; a second array of second bobbins each for carrying wire to be braided; a respective wire guide means for each said second bobbin; the wire from each said second bobbin being guided by its said wire guide means; second moving means for supporting and for moving said guide means annularly around said axis in a second direction opposite said first direction; cam means for shifting all said guide means radially of said axis; said cam means being mounted to and being rotatable with said first bobbins; cam follower means on at least some of said guide means, said cam follower means being in engagement with said cam means for being shifted by said cam means; each said cam follower means being so connected with its said guide means that shifting of said cam follower means in a third direction shifts said guide means radially inwardly of said axis and shifting of said cam follower means in a fourth direction opposite said third direction shifts said guide means radially outwardly of said axis; said cam means being shaped so as to cause each said cam follower means to cause its said guide means to shift radially inwardly of all said first bobbins, thereby enabling said guide means to pass by said first bobbins radially inwardly thereof and to cause each said guide means to shift radially outwardly of all said first bobbins, thereby enabling said guide means to pass by said first bobbins radially outwardly thereof; said cam means comprising at least one cam follower guide pathway having first cam follower shift sections which shift said cam followers in said third direction, first cam follower travel sections over which said cam followers travel after they have moved in said third direction, second cam follower shift sections which shift said cam followers in said fourth direction and second cam follower travel sections over which said cam followers travel after they have moved in said fourth direction; said cam follower first and second shift sections being located on said cam means so as to radially shift said guide means through the space between neighboring said first bobbins without engagement between said first bobbins and said guide means.
Claim 3
Dependent Claim
46 words
