Abstract
A handle for holding a tool piece comprising: a fore end region and an aft end region; an edge at the fore end region of the handle defining an opening for inserting a tool piece; and a clamp connected to the fore end region of the handle comprising a pair of selectively movable, substantially diametrically opposed arms. A handle for a broken key extractor, the handle capable of holding a selectively removable 0.050-inch broken key extractor blade such that a tensile force of at least about 50 pounds is required to remove the blade from the handle using a SCOTT J Model Tensile Tester.
Claims45
A tool comprising:
- (a) a handle extending along a longitudinal axis, the handle comprising a fore end region and an aft end region;
- (b) a removable tool piece connected to the fore end region of the handle;
- and
- (c) a clamp for removably connecting the tool piece to the handle, the clamp connected to the fore end region of the handle and comprising opposing arm portions, each opposing arm portion extending transverse the longitudinal axis through a portion of the handle.
A broken key extractor comprising:
- (a) a handle having a fore end region and an aft end region;
- (b) a blade-holding aperture having an open end and a base end, the aperture defined by at least a portion of the fore end region of the handle;
- (c) a pair of setscrews;
- (d) a channel sized to receive the setscrews, the channel having two open ends defined by the handle, wherein the channel substantially intersects the blade-holding aperture, whereby opposing the pair of set screws in the channel creates a clamp;
- and
- (e) an extractor blade for gripping broken keys, the blade sized to be received by the open end of the blade-holding aperture and sized to rest on the base end of the blade-holding aperture, wherein the blade is held in place by the pair of opposing set screws.
A broken key extractor comprising:
- (a) a handle having a fore end region and an aft end region;
- (b) a blade-holding aperture having an open end and a base end, the aperture defined by at least a portion of the fore end region of the handle;
- (c) a pair of diametrically opposed rods;
- (d) an interior wall defining a channel in the fore end region of the handle, the channel for receiving the pair of diametrically opposed rods, the channel substantially intersecting the blade-holding aperture and having two open ends defined by the handle, whereby diametrically opposing the pair rods in the channel creates a clamp for holding an extractor blade;
- and
- (e) an extractor blade for gripping broken keys, the blade sized to be received by the open end of the blade-holding aperture and rest on the base end of the blade-holding aperture, wherein the blade is held in place by the pair of diametrically opposed rods.
A handle for holding a tool piece comprising:
- (a) a fore end region and an aft end region;
- (b) an edge at the fore end region of the handle defining an opening for inserting a tool piece;
- and
- (c) a clamp connected to the fore end region of the handle comprising a pair of selectively movable, substantially diametrically opposed arms.
A handle for a broken key extractor comprising:
- (a) a fore end region and an aft end region;
- (b) an edge in the fore end region of the handle defining an opening for inserting an extractor blade;
- and
- (c) a clamp connected to the fore end region of the handle comprising a pair of arms substantially diametrically opposed along a clamp axis, each arm movable along the axis toward the opposing arm.
A blade holder for a broken key extractor comprising:
- (a) a handle disposed along a longitudinal axis, the handle comprising a fore end region and an aft end region;
- (b) an edge in the fore end region of the handle defining an opening for inserting a blade;
- and
- (c) a substantially cylindrical wall defining a channel extending substantially transverse the longitudinal axis of the handle.
A broken key extractor comprising:
- (a) a handle having a fore end region, wherein the handle fore end region at least partially defines a blade-holding aperture;
- (b) a pair of substantially diametrically opposed rods;
- (c) an interior wall defining a channel for receiving the pair of substantially diametrically opposed rods;
- and
- (d) an extractor blade for gripping broken keys, the blade sized to be received by the blade-holding aperture.
A clamp for connecting a tool piece to a handle, the clamp comprising:
- (a) at least two arms at least partially defining an aperture having at least one open end, the aperture at least partially within the handle, each arm selectively movable toward the aperture at least partially defined by the arms;
- and
- (b) an interior wall within the handle at least partially defining the space for inserting the tool piece.
A broken key extractor comprising a handle and a selectively removable 0.050-inch extractor blade wherein a tensile force of at least about 50 pounds is required to remove the blade from the handle using a SCOTT J Model Tensile Tester.
A handle for a broken key extractor, the handle capable of holding a selectively removable 0.050-inch broken key extractor blade such that a tensile force of at least about 50 pounds is required to remove the blade from the handle using a SCOTT J Model Tensile Tester.
