Cutting, Stripping And Wrapping Bit

View page
US Patent:
43801110, Apr 19, 1983
Filed:
Sep 8, 1980
Appl. No.:
6/184763
Inventors:
Clifford L. Galloup - Reed City MI
Roger M. Bula - Reed City MI
Robert W. Klemm - Hersey MI
Ralph E. Westerburg - Reed City MI
Assignee:
Cooper Industries, Inc. - Houston TX
International Classification:
H01R 4304
B21F 1504
US Classification:
295644
Abstract:
A combination bit for cutting and stripping insulation from a solid flexible conductor wire and wrapping a stripped end portion of the wire on a terminal in a series of helical convolutions includes a cooperable sleeve having a wall portion forming a guide surface for permitting insertion of the wire into a groove formed on the periphery of the bit. A cutting blade disposed in the groove includes opposed straight cutting edge portions one of which is proportioned such that it engages the insulation of the conductor wire initially in a position which places said edge parallel to a cooperative flat surface portion on said sleeve and tangent to the circumference of the wire insulation. The bit and sleeve are proportioned so as to provide for initial engagement of the insulation by the conductor wire within approximately five degrees of angular rotation of the bit from its starting point.

Magnet Wire Wrapping Bit

US Patent:
44678428, Aug 28, 1984
Filed:
May 2, 1983
Appl. No.:
6/490670
Inventors:
Clifford L. Galloup - Reed City MI
Roger M. Bula - Big Rapids MI
Assignee:
Cooper Industries, Inc. - Houston TX
International Classification:
B21F 300
US Classification:
140124
Abstract:
A device for stripping insulation from magnet wire and wrapping the stripped wire around a terminal in a series of helical convolutions is described. The device includes the normal rotatable wrapping bit having a wire receiving groove disposed on the periphery of the bit, this groove being radially offset from a terminal receiving bore in the bit. The device includes a fixed sleeve surrounding the bit with a wire receiving slot extending outwardly therefrom. It has a hooked shaped insulation stripping edge positioned transversely of the wire path and being radially positioned inwardly from the groove. The stripping edge is angularly positioned between the groove and the wire receiving slot, this angular position controlling the tension of the magnet wire as it moves over the hook, this tension being sufficiently great to create a concentrated force at the junction between the insulation and the gripping edge so as to strip a limited portion of the insulation from the inner surface of the wire which is to be placed over the terminal by the wrapping tool, this stripping and wrapping taking place essentially simultaneously. The device is particularly adapted for stripping tenacious film insulation from magnet wire.

Electric Conductor Wrapping Tool

US Patent:
42841097, Aug 18, 1981
Filed:
Oct 19, 1979
Appl. No.:
6/086425
Inventors:
Paul R. Kilmer - Leroy MI
Roger M. Bula - Reed City MI
Assignee:
Cooper Industries, Inc. - Houston TX
International Classification:
B21F 1504
US Classification:
140122
Abstract:
In a hand-held power tool (10) for wrapping conductor around an electrical terminal, a drive means (14, 34 and 42) is selectively engaged with a clutch (58) mounted on a drive shaft (44) journaled within index means (62) in axial arrangement within a case (12). The drive means (14, 34 and 42) and index means (62) are secured to the case (12) by means of circular tongue and groove structure of radially stepped configuration. Resilient ring members (60) are frictionally engaged between the drive means (14, 34 and 42) and the drive shaft (44) to provide for gradual arrest of the drive means after disengagement of the clutch means (58) and stoppage of the drive shaft by the index means (62). A trigger (22) within the case (12) controls actuation of the drive means (14, 34 and 42) and engagement of the clutch means (58) therewith.
