Abstract
Abstract A bit for wrapping a conductor around a terminal in successive convolutions in which the end face of the bit is formed by a channel extending across the face at generally right angles to the axis of the bit, said channel being symmetrical with reference to an opening for receiving the terminal about which the conductor is wound with the sides of the channel providing the camming surfaces for urging the conductor against the terminal and axially along the terminal.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
146 words
In a device for wrapping a conductor around a terminal in successive convolutions: a. a rotatable wrapping bit having an end face; b. said bit defining terminal-receiving means and conductorreceiving means with both means opening to said end face; c. said end face defining a first surface means sloping with respect to the axis of the terminal-receiving means for camming a conductor convolution radially toward a terminal disposed in said terminal-receiving means and axially forwardly into engagement with a next preceding convolution wrapped around the terminal; d. said sloping means being defined by a channel extending completely across the end face of said bit and symmetrical with reference to said terminal-receiVing means; and e. said channel having a land in a plane at right angles to the axis of said bit extending radially 360* from the terminalreceiving means and said sloping surface extending from said land.
Claim 2
Dependent Claim
146 words
In a device for wrapping a conductor around a terminal in successive convolutions: a. a rotatable wrapping bit having an end face; b. said bit defining terminal-receiving means and conductorreceiving means with both means opening to said end face; c. said end face defining a first surface means sloping with respect to the axis of the terminal-receiving means for camming a conductor convolution radially toward a terminal disposed in said terminal-receiving means and axially forwardly into engagement with a next preceding convolution wrapped around the terminal; d. said sloping means being defined by a channel extending completely across the end face of said bit and symmetrical with reference to said terminal-receiVing means; and e. said channel having a land in a plane at right angles to the axis of said bit extending radially 360* from the terminalreceiving means and said sloping surface extending from said land.
Claim 3
Dependent Claim
180 words
In a device for wrapping a conductor around a terminal in successive convolutions: a. a rotatable wrapping bit having an end face; b. said bit defining terminal-receiving means and conductor-receiving means with both means opening to said end face; c. said end face defining a first surface means sloping with respect to the axis of the terminal-receiving means for camming a conductor convolution radially toward a terminal disposed in said terminal-receiving means and axially forwardly into engagement with a next preceding convolution wrapped around the terminal d. said sloping means being defined by a channel extending completely across the end face of said bit and symmetrical with reference to said terminal-receiving means; e. said channel having a land in a plane at right angles to the axis of said bit extending radially from the terminal-receiving means and said sloping surface extending from said land; f. said channel has two axially spaced lands in a plane at right angles to the axis of said bit extending radially from the terminal-receiving means, and two radially spaced sloping surfaces extending from said lands.
Claim 4
Dependent Claim
180 words
In a device for wrapping a conductor around a terminal in successive convolutions: a. a rotatable wrapping bit having an end face; b. said bit defining terminal-receiving means and conductor-receiving means with both means opening to said end face; c. said end face defining a first surface means sloping with respect to the axis of the terminal-receiving means for camming a conductor convolution radially toward a terminal disposed in said terminal-receiving means and axially forwardly into engagement with a next preceding convolution wrapped around the terminal d. said sloping means being defined by a channel extending completely across the end face of said bit and symmetrical with reference to said terminal-receiving means; e. said channel having a land in a plane at right angles to the axis of said bit extending radially from the terminal-receiving means and said sloping surface extending from said land; f. said channel has two axially spaced lands in a plane at right angles to the axis of said bit extending radially from the terminal-receiving means, and two radially spaced sloping surfaces extending from said lands.
Claim 5
Dependent Claim
22 words
A device as in claim 2 wherein g. two conductor receiving means are provided diametrically opposed to each other and axially parallel.
