Abstract
Abstract Wire wrapping equipment is provided in the form of a novel bit for a wire wrap machine. The bit has the capability of removing insulation from a wire and then wrapping the bared wire around a terminal. To perform these functions the bit includes a rotary shaft supported within a cylindrical element. The cylindrical element and the rotary shaft couple directly to the wire wrap machine which holds the cylindrical element in a fixed position while coupling the rotary element to a drive shaft. An insulated wire to be wrapped is inserted into a slot on the rotary element, under a cutting element on the rotary element and over a slot fixed to the cylindrical element. A terminal to be wrapped is inserted into a hole in the end of the rotary element. When the rotary element is turned, insulation is severed by the cutting element, and the wire is pulled from the insulation by coaction of the rotary element and the slot in the fixed element. With further rotation, the bared wire is wrapped around the terminal.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
103 words
A wire wrapping unit in the form of a bit for use with a wire wrapping gun, comprising: a rotary element supported axially within a stationary cylindrical element; means forming an integral part of said rotary element for receiving the end of an insulated wire; means coupling to said rotary element for holding the end of said insulated wire; means integral with said rotary element for severing insulation near the end of said wire; and means coupling to the stationary cylindrical element for pulling said wire from said severed insulation as the rotary element turns to provide an end segment of bare wire.
Claim 2
Dependent Claim
103 words
A wire wrapping unit in the form of a bit for use with a wire wrapping gun, comprising: a rotary element supported axially within a stationary cylindrical element; means forming an integral part of said rotary element for receiving the end of an insulated wire; means coupling to said rotary element for holding the end of said insulated wire; means integral with said rotary element for severing insulation near the end of said wire; and means coupling to the stationary cylindrical element for pulling said wire from said severed insulation as the rotary element turns to provide an end segment of bare wire.
Claim 3
Dependent Claim
59 words
A wire wrapping unit as claimed in claim 1, in which the means for severing insulation near the end of a wire includes: a cutting element fixed to the rotary element in a position to engage said insulation; and whereby rotation of said rotary element forces said insulated wire into contact with the cutting element and severs the insulation.
Claim 4
Dependent Claim
54 words
A wire wrapping unit as claimed in claim 1, including: means associated with said rotary element for receiving the end of a terminal; and means associated with the stationary cylindrical element for holding said insulated wire and forcing the end segment of bare wire to wrap around the terminal when the rotary element turns.
Claim 5
Dependent Claim
34 words
A wire s wrapping unit as claimed in claim 1, in which the rotary element and the stationary cylindrical element together form a bit operable in the chuck of a wire wrap driver machine.
Claim 6
Dependent Claim
28 words
A wire wrapping unit as claimed in claim 4, in which the means for receiving the end of an insulated wire includes a slot in said rotary element.
Claim 7
Dependent Claim
28 words
A wire wrapping unit as claimed in claim 1, in which the means for receiving the end of an insulated wire includes a slot in said rotary element.
Claim 8
Dependent Claim
37 words
A wire wrapping unit as claimed in claim 6, in which the means for holding the end of an insulated wire includes a retaining element extending over said slot to keep said insulated wire in said slot.
Claim 9
Dependent Claim
53 words
A wire wrapping unit as claimed in claim 4, in which the means for pulling said wire from said severed insulation includes means on said the stationary cylindrical element for supporting said wire and providing a pull on said insult insulated wire as said rotary element turns and pulls on said severed insulation.
Claim 10
Dependent Claim
44 words
A wire wrapping unit as claimed in claim 1, in which the means for pulling said wire from said severed insulation to provide an end segment of bare wire includes means serving to hold said bare wire while it is wrapped around a terminal.
Claim 11
Dependent Claim
131 words
A wire wrapping device comprising: a rotary shaft including means integral thereto for receiving and holding one end of an insulated wire; a fixed element for supporting and retaining a portion of said insulated wire in a fixed position relative to said one end; said rotary shaft including cutting means integral thereto for removing insulation from said one end of said insulated wire; said rotary shaft including a receptacle into which an electrical terminal may be inserted; said cutting means serving to sever the insulation from said wire permitting a strip of bare wire to be pulled from the insulation when the rotary element turns; and said rotary shaft forcing the bare wire to twist around said terminal to form a firm electrical connection between said terminal and said bare wire.
Claim 12
Dependent Claim
131 words
A wire wrapping device comprising: a rotary shaft including means integral thereto for receiving and holding one end of an insulated wire; a fixed element for supporting and retaining a portion of said insulated wire in a fixed position relative to said one end; said rotary shaft including cutting means integral thereto for removing insulation from said one end of said insulated wire; said rotary shaft including a receptacle into which an electrical terminal may be inserted; said cutting means serving to sever the insulation from said wire permitting a strip of bare wire to be pulled from the insulation when the rotary element turns; and said rotary shaft forcing the bare wire to twist around said terminal to form a firm electrical connection between said terminal and said bare wire.
