Abstract
Abstract A bit and sleeve assembly for cutting, stripping and wrapping an insulated conductor comprising a rotary wrapping bit mounted within a fixed tubular sleeve. The bit includes a longitudinal conductor receiving groove having disposed therein a transverse cutting edge or blade insert cooperable with the sleeve to cut the conductor insulation upon commencement of the wrapping operation. The sleeve includes a radially extended wall portion forming an opening to the bit end face which is alignable with the conductor receiving groove to facilitate loading an insulated conductor into the groove. An opening in the sleeve alignable with the conductor receiving groove defines a cutting edge cooperable with the bit to cut a predetermined length of wire to be wrapped.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
177 words
In a device for stripping insulation from a flexible conductor wire and wrapping said wire on a terminal in a series of helical convolutions: a rotatable wrapping bit comprising; a bit end face; a terminal receiving bore opening to said end face; a longitudinal wire receiving groove disposed on the periphery of said bit and radially offset from said terminal receiving bore and opening at one end to said end face; and a cutting edge disposed in said groove for cutting the insulation of a wire disposed in said groove; and, an elongated tubular sleeve fixed substantially axially with respect to said bit and disposed around said bit to substantially enclose a major portion of said groove, one end of said sleeve being disposed adjacent said end fae, said sleeve including means comprising a radially outwardly relieved tubular wall portion extending axially from said one end of said sleeve toward said cutting edge and forming an opening to provide for inserting said wire longitudinally with respect to said bit past said cutting edge and into said groove.
Claim 2
Dependent Claim
177 words
In a device for stripping insulation from a flexible conductor wire and wrapping said wire on a terminal in a series of helical convolutions: a rotatable wrapping bit comprising; a bit end face; a terminal receiving bore opening to said end face; a longitudinal wire receiving groove disposed on the periphery of said bit and radially offset from said terminal receiving bore and opening at one end to said end face; and a cutting edge disposed in said groove for cutting the insulation of a wire disposed in said groove; and, an elongated tubular sleeve fixed substantially axially with respect to said bit and disposed around said bit to substantially enclose a major portion of said groove, one end of said sleeve being disposed adjacent said end fae, said sleeve including means comprising a radially outwardly relieved tubular wall portion extending axially from said one end of said sleeve toward said cutting edge and forming an opening to provide for inserting said wire longitudinally with respect to said bit past said cutting edge and into said groove.
Claim 3
Dependent Claim
145 words
In a device for stripping insulation from a portion of a flexible conductor wire and wrapping said portion on a terminal in a series of helical convolutions: a rotatable wrapping bit comprising; a bit end face; a terminal receiving bore opening to said end face; a conductor receiving groove disposed on the periphery of sad bit parallel to and radially offset from said terminal receiving bore and opening at one end to said end face; and a cutting edge disposed in said groove for cutting the insulation of an insulated conductor wire disposed in said groove; said cutting edge being formed on a cutting blade removably retained in a transverse slot formed in said bit and intersecting said groove; and, an elongated tubular sleeve fixed axially with respect to said bit and disposed around said bit to substantially enclose a major portion of said groove.
Claim 4
Dependent Claim
145 words
In a device for stripping insulation from a portion of a flexible conductor wire and wrapping said portion on a terminal in a series of helical convolutions: a rotatable wrapping bit comprising; a bit end face; a terminal receiving bore opening to said end face; a conductor receiving groove disposed on the periphery of sad bit parallel to and radially offset from said terminal receiving bore and opening at one end to said end face; and a cutting edge disposed in said groove for cutting the insulation of an insulated conductor wire disposed in said groove; said cutting edge being formed on a cutting blade removably retained in a transverse slot formed in said bit and intersecting said groove; and, an elongated tubular sleeve fixed axially with respect to said bit and disposed around said bit to substantially enclose a major portion of said groove.
Claim 5
Dependent Claim
19 words
The invention set forth in claim 2 wherein: said cutting blade is retained in said groove by said sleeve.
Claim 6
Dependent Claim
30 words
The invention set forth in claim 1 wherein: said radially outwardly relieved wall portion forms a guide surface extending from said one end of said sleeve to said cutting edge.
Claim 7
Dependent Claim
48 words
The invention set forth in claim 4 wherein: said sleeve includes an opening disposed adjacent the end of said groove opposite said one end and forming a cutting edge for severing an end portion of a wire disposed in said groove in response to rotation of said bit.
Claim 8
Dependent Claim
29 words
The invention set forth in claim 5 wherein: said guide surface is axially aligned with said opening forming a cutting edge for severing an end portion of a wire.
