Patent number: 6315060Abstract: A collet assembly is provided that securely holds tool bit shafts therein while allowing them to be readily and easily interchanged. The collet assembly herein has a very few number of parts and is easily assembled without the need for any special tools or machines therefor. In a preferred form, the collet assembly provides for release of the tool shaft by a forward sliding action of a collet sleeve. In this manner, rearward forces acting on the sleeve in an axial direction such as can occur during tool operations will not cause the tool shaft to be accidentally released. Another advantage is the use of a retaining member for releasably holding the shaft. The retaining member avoids the use of detent balls as in prior collets which can require ramp surfaces formed to very precise tolerances to engage and shift the balls into and out of a holding position on the shaft.Type: GrantFiled: December 30, 1999Date of Patent: November 13, 2001Assignee: Wilton Tool Company, LLCInventors: David J.

Patent number: 6101726Abstract: A saw blade clamp (1) comprises a body (3) defining a channel (13) for a saw blade (11), a retaining member (17), biasing means (19) for continuously urging the retaining member (17) towards the channel (13) to abut a saw blade (11) in use in the channel (13), and a release device (30) separate from the retaining member (17) and the biasing means (19). When activated the release device (30) acts on the retaining member (17) to move the retaining member (17) away from the channel (13) to allow a saw blade (11) to be entered into or removed from the channel (13).Type: GrantFiled: February 27, 1997Date of Patent: August 15, 2000Assignee: Black & Decker Inc.Inventor: Ray Laverick

Patent number: 6083146Abstract: A plastic tool pocket mounts to tool storage chain in a machining center. The tools all have a hollow, tapered tool shank, which fits into tool pocket. The hollow tool shank has an internal relief and retention groove for securing the tool shank with a machine spindle. The tool pocket has central support shaft, having a circular spring ring loosely fitted into an annular clearance groove. When the tool shank slides over the support shaft, the circular ring first deflects radially into the clearance groove, then pops out into the retention groove, to hold the tool shank in position.Type: GrantFiled: September 8, 1998Date of Patent: July 4, 2000Assignee: Unova IP CorporationInventor: Marvin G. Earley, Jr.

Patent number: 6009627Abstract: A saw blade clamping arrangement particularly for power reciprocating saws and similar tools having a reciprocating shaft connected to a cutting member includes a biasing member preferably in the form of a spring clamp member. The biasing member is interconnected with the drive shaft and operative for providing a biasing force to retain the cutting member in operative connection with the drive shaft. A release lever is pivotally mounted to a housing of the saw for movement between first and second position. In the first position the release lever is spaced apart from the biasing member. In the second position the release lever engages the biasing member and opposes the biasing force of the biasing member to permit quick and easy removal and replacement of the saw blade. The spring clamp member biases the saw blade into operative engagement with the drive shaft. In a second preferred embodiment, the spring clamp member biases a locking member into engagement with the saw blade.Type: GrantFiled: June 24, 1997Date of Patent: January 4, 2000Assignee: Black & Decker Inc.Inventors: Stephen C Dassoulas, Jason R. Melvin, Robert G. Moores, Jr.

Patent number: 5794352Abstract: A saw blade clamping arrangement particularly for power reciprocating saws and similar tools having a reciprocating shaft connected to a cutting member includes a biasing member preferably in the form of a spring clamp member. The biasing member is interconnected with the drive shaft and operative for providing a biasing force to retain the cutting member in operative connection with the drive shaft. A release lever is pivotally mounted to a housing of the saw for movement between first and second stable position. In the first position the release lever is spaced apart from the biasing member. In the second position the release lever engages the biasing member and opposes the biasing force of the biasing member to permit quick and easy removal and replacement of the saw blade. In one preferred embodiment, the spring clamp member biases the saw blade into operative engagement with the drive shaft.Type: GrantFiled: November 5, 1996Date of Patent: August 18, 1998Assignee: Black & Decker Inc.Inventor: Stephen C. Dassoulas

Patent number: 5785468Abstract: A drill for interchangable use on a screw driver bit. The drill is mounted on shank, the shank having an opening at the end remote from the drill for rapid placement of the shank on and removal of the shank from the screw driver bit locked in the chuck of an electric powered rotating unit to permit drilling a screw hole and then, upon removal of the drill from the screw driver bit using the screw driver bit for installation of a screw. A countersink may be also be mounted on the shank with the drill.Type: GrantFiled: April 22, 1996Date of Patent: July 28, 1998Inventor: Mark Peritz

Patent number: 5784788Abstract: A cutting tool for piercing a sealant surrounding a vehicle windshield including a cylindrically shape body which is internally hollowed and first and second blade housing members which, upon assembly, are axially slidably mounted within a first selected end of the body and form a blade receiving cavity. A blade includes a first insertable portion with at least one aperture and a second cutting portion extending at a desired angle with respect to the insertable portion. A spring loaded tang is mounted within the second blade housing member and is upwardly biased so that an upwardly projecting button portion engages through the at least one aperture of the blade insertable portion in a first blade retaining position. An inwardly displaceable disengaging member is axially slidably mounted within a second selected end of the body and is contoured along a forward face so that it unseats the spring loaded from the blade aperture in a second blade release position.Type: GrantFiled: March 6, 1997Date of Patent: July 28, 1998Assignee: Reid ManufacturingInventor: Jeffrey R. Cothery

Patent number: 5611650Abstract: A mounting assembly that secures a tooling plate to a base plate. The base plate has a mounting aperture which receives a pin that extends from the tooling plate. The pin has a locking aperture located essentially perpendicular to the longitudinal axis of the pin. Located within the mounting aperture is an armature which has a lip that extends into the locking aperture when the tooling plate is placed onto the base plate and the pin is inserted into the mounting aperture. The interlocking armature and pin secure the tooling plate to the base plate. The pin and armature lip have cooperating chamfered cam surfaces that move the lip into the locking aperture when the pin is inserted into the mounting aperture. The assembly includes a spring biased button that can be depressed to move the armature out of the pin so that the tooling plate can be released from the base plate.Type: GrantFiled: August 16, 1995Date of Patent: March 18, 1997Assignee: Laurence/WayneInventors: Richard W. Perkins, Bradley L. Read

Patent number: 5481949Abstract: A locking member including a sleeve and a U-shaped plate. The sleeve has an axial hole at one end thereof and its outer surface is provided with an annular groove having a pair of holes arranged face-to-face with each other. The U-shaped plate has clamp portions having protrusions which penetrate through the holes in the groove of the sleeve to project within the axial hole of the sleeve for temporarily clamping a rod object inserted into the sleeve.Type: GrantFiled: August 15, 1994Date of Patent: January 9, 1996Inventor: En-Ji Yen
