Abstract
Abstract Apparatus for winding a coil by feeding wire from a wire guide to a rotating bobbin and for terminating the coil by orbiting the wire guide about terminals projecting from the bobbin is made more versatile by mounting the wire guide so that it can be rotated from a position in which it feeds wire in a direction perpendicular to the bobbin axis to a position in which it feeds wire in a direction parallel to the bobbin axis. This construction permits termination of the coils upon terminals projecting from the bobbin in a direction parallel to the bobbin axis as well as those perpendicular to the bobbin axis. Introducing an offset portion to the spindle upon which the bobbin is rotated permits the wire guide to be brought into a position in which it can wrap a terminal projecting parallel to the coil axis on the inner or spindle side of the bobbin.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
251 words
An apparatus for winding and terminating an electrical coil by winding wire into a coil on a bobbin having projecting terminals and by wrapping the wire ends of the coil about the terminals, said apparatus comprising: a. a rotatable spindle adapted to support a bobbin mounted on the end thereof with its axis essentially coincident with the axis of rotation of the spindle, said bobbin supporting electrical terminals projecting therefrom; b. a wire guide for feeding wire to said bobbin and terminals; means for extending said wire guide away from its support means so as to have a free end; a wire delivery opening adjacent said free end through which the wire is fed to the bobbin or terminals; a rotatable member by means of which the wire guide can be rotated about an axis essentially perpendicular to the axis of the spindle; motor means for rotating said rotatable member so that the wire can be fed perpendicular to the spindle axis during the winding of the bobbin and can be fed perpendicular or parallel to the spindle axis during the wrapping of the wire about the terminals; and c. supporting carriage means by which the wire guide and spindle can be moved in three mutually perpendicular directions with respect to one another and motor means for moving said carriage means so that the wire guide and a terminal can be moved into juxtaposition and an orbiting motion imparted to the wire guide so as to wrap the terminal with wire.
Claim 2
Independent Claim
251 words
An apparatus for winding and terminating an electrical coil by winding wire into a coil on a bobbin having projecting terminals and by wrapping the wire ends of the coil about the terminals, said apparatus comprising: a. a rotatable spindle adapted to support a bobbin mounted on the end thereof with its axis essentially coincident with the axis of rotation of the spindle, said bobbin supporting electrical terminals projecting therefrom; b. a wire guide for feeding wire to said bobbin and terminals; means for extending said wire guide away from its support means so as to have a free end; a wire delivery opening adjacent said free end through which the wire is fed to the bobbin or terminals; a rotatable member by means of which the wire guide can be rotated about an axis essentially perpendicular to the axis of the spindle; motor means for rotating said rotatable member so that the wire can be fed perpendicular to the spindle axis during the winding of the bobbin and can be fed perpendicular or parallel to the spindle axis during the wrapping of the wire about the terminals; and c. supporting carriage means by which the wire guide and spindle can be moved in three mutually perpendicular directions with respect to one another and motor means for moving said carriage means so that the wire guide and a terminal can be moved into juxtaposition and an orbiting motion imparted to the wire guide so as to wrap the terminal with wire.
Claim 3
Dependent Claim
45 words
In apparatus as described in claim 1, the further improvement wherein the spindle is constructed with an offset portion permitting the wire guide to assume a position parallel to the bobbin axis on the spindle side of the bobbin when wrapping wire about said terminal.
Claim 4
Independent Claim
309 words
An apparatus for winding and terminating an electrical coil by winding wire into a coil on a bobbin having projecting terminals and by wrapping the wire ends of the coil about the terminals, said apparatus comprising: a. a rotatable spindle adapted to support a bobbin mounted on the end thereof with its axis essentially coincident with the axis of rotation of the spindle, said bobbin supporting electrical terminals projecting therefrom; b. means of moving said spindle linearly along the axis of rotation, comprising support block and motor means for moving said support block so as to position the spindle so that either the coil winding portion of the bobbin or the terminals on the bobbin are adjacent to the wire guide; c. a wire guide for feeding wire to said bobbin and terminals; means for extending said wire guide away from its support means so as to have a free end; a wire delivery opening adjacent said free end through which the wire is fed to the bobbin or terminals; a rotatable member by means of which the wire guide can be rotated about an axis essentially perpendicular to the axis of the spindle; motor means for rotating said rotatable member so that the wire can be fed perpendicular to the spindle axis during the winding of the bobbin, and can be fed perpendicular or parallel to the spindle axis during the wrapping of the wire about the terminals; and d. a means of moving said wire guide comprising a carriage support movable in two mutually perpendicular directions which are each mutually perpendicular to the axis of rotation of the spindle, and motor means for moving said carriage support so that the wire guide can be moved into juxtaposition with a terminal and an orbiting motion imparted to the wire guide so as to wrap the terminal with wire.
Claim 5

An apparatus for winding and terminating an electrical coil by winding wire into a coil on a bobbin having projecting terminals and by wrapping the wire ends of the coil about the terminals, said apparatus comprising: a. a rotatable spindle adapted to support a bobbin mounted on the end thereof with its axis essentially coincident with the axis of rotation of the spindle, said bobbin supporting electrical terminals projecting therefrom; b. means of moving said spindle linearly along the axis of rotation, comprising support block and motor means for moving said support block so as to position the spindle so that either the coil winding portion of the bobbin or the terminals on the bobbin are adjacent to the wire guide; c. a wire guide for feeding wire to said bobbin and terminals; means for extending said wire guide away from its support means so as to have a free end; a wire delivery opening adjacent said free end through which the wire is fed to the bobbin or terminals; a rotatable member by means of which the wire guide can be rotated about an axis essentially perpendicular to the axis of the spindle; motor means for rotating said rotatable member so that the wire can be fed perpendicular to the spindle axis during the winding of the bobbin, and can be fed perpendicular or parallel to the spindle axis during the wrapping of the wire about the terminals; and d. a means of moving said wire guide comprising a carriage support movable in two mutually perpendicular directions which are each mutually perpendicular to the axis of rotation of the spindle, and motor means for moving said carriage support so that the wire guide can be moved into juxtaposition with a terminal and an orbiting motion imparted to the wire guide so as to wrap the terminal with wire.
Claim 6
Dependent Claim
60 words
In apparatus as described in claim 3, the further improvement wherein the spindle is constructed with an offset portion pemitting the wire guide to assume a position in juxtaposition with a terminal parallel to the bobbin axis on the spindle side of the bobbin so that the wire can be wrapped about said terminal by orbiting of the wire guide.
