US 6,044,744 A · Fiber optic cable sheath removal tool

Abstract

A cutting tool (10) for making precise circumferential and longitudinal cuts in an fiber optic cable (12) includes a rotary-driven cutting wheel (18) that extends partially into the top of a housing (24) having an open bottom. The housing receives a pair of upper and lower cable guides that have opposed longitudinal and transverse channels (36 and 42) and 38 and 44) for retaining the cable in a longitudinal and transverse relationship, respectively with the cutting wheel. A cable lock guide (48) attaches to the bottom of the housing to maintain the guides in a fixed relationship while an adjustment mechanism (52) extends through the guide lock to displace the guides (and the cable retained therebetween) towards the cutting wheel to control the depth of cut. By placing the cable in the longitudinal channels in the guides, the tool can make a longitudinal cut when displaced along the axis of the cable. By placing the cable in the transverse channels in the guides, the tool can make a circumferential cut when rotated about the cable axis.

Dependent claims

A tool for making at least one of a longitudinal and circumferential sheath cuts in a cylindrical member comprising:

a rotary driven cutting wheel for rotation about an axis;
a housing in spaced relationship from the cutting wheel such that a portion of the cutting wheel extends into the top of the housing, the housing having openings in its sides and ends to permit the cylindrical object to pass therethrough in a transverse direction that is parallel to said cutting wheel rotational axis and a longitudinal direction perpendicular to the axis of cutting wheel rotation;
upper and lower guides for receipt within said housing to circumscribe the cylindrical object to maintain the object fixed in one of the transverse and longitudinal directions to enable the cutting wheel to make one of a circumferential and longitudinal cuts, respectively, in said object;
and
a guide lock for releasable mounting to the bottom of the housing to retain said guides in said housing;
and
an adjustment mechanism for displacing said guides towards said cutting wheel to control the depth of cut of said wheel into said object.

A method for making a precise cut about the circumference of a cylindrical object (a "circumferential cut") with a cutting wheel that rotates about an axis, comprising the steps of:

seating the cylindrical object in opposed channels in upper and lower guides, the channels each extending along a first axis;
receiving the upper and lower guides in a housing having an open bottom and an open top into which the rotary-driven cutting wheel extends to extend at least in part into the upper guide member so that the cutting wheel axis of rotation is parallel to the first axis along which the channels extend to enable the cutting wheel to make a circumferential cut in said object once said object contacts the cutting wheel;
releasably securing a guide lock to the bottom of the housing to retain guides in a fixed relationship relative to the cutting wheel;
manipulating an adjusting mechanism carried by the guide lock to displace the guide members, and the object circumscribed thereby, towards the cutting wheel to control the depth of cut by said wheel;
rotating the cutting wheel relative to the object about the first axis to cut the object about its circumference.

A method for making a precise longitudinal cut in a cylindrical object along its longitudinal axis with a cutting wheel that rotates about an axis generally perpendicular to the longitudinal axis of the object, comprising the steps of:

circumscribing the cylindrical object in opposed longitudinal channels in upper and lower guides;
receiving the upper and lower guides in a housing having an open bottom and an open top into which a rotary-driven cutting wheel extends at least in part into the upper guide member with its axis perpendicular to the axis of the object for making a longitudinal cut therein once said object contacts the cutting wheel;
releasably securing a guide lock to the bottom of the housing to retain guides in a fixed relationship relative to the cutting wheel;
manipulating an adjusting mechanism carried by the guide lock to displace the guide members, and the object circumscribed thereby, towards the cutting wheel to control the depth of cut by said wheel;
displacing the cutting wheel relative to the object along the longitudinal axis of the object to cut the object longitudinally.
