  • Patent number: 6142485
    Abstract: A chuck for rotary tools with a cylindrical chucking shank encloses such shank with a basic body. A radial through-hole in basic body serves to receive a clamping screw which applies pressure to a clamping member which is seated inside a through-hole between the clamping screw and chucking shank. A clamping member is provided with a radial projection and the through-hole with a cross-sectional narrowing along its inner end. In between the radial projection and the narrowing is an elastically compressible spring element which, due to its return force, lifts the clamping element away from the chucking shank and pushes it back into the through-hole when it is not under tension from the clamping screw.

  • Patent number: 6116966
    Abstract: Disclosed are male and female electrical contacts for transferring high electrical power between a master assembly and a tool assembly of a robotic tool changer. The male and female contacts have corresponding outwardly-projecting and inwardly recessed conical or frusto-conical contact surfaces which tend to cause contaminants to slide off the surface of the contacts. The contacts may instead have corresponding outwardly-projecting and inwardly recessed contact surfaces having spherical, frusto-spherical, ellipsoid, frusto-ellipsoid, ovoid, or frusto-ovoid shapes. Each of the contacts includes a contact base for attaching the contact to one of the assemblies of the robotic tool changer and a contact tip removably attached to the contact base, thereby allowing the contact tip to be replaced without detaching the contact base from the robotic tool changer. The contact tip of either or both of the electrical contacts is mounted in such a way as to have compliance in at least one direction.

  • Patent number: 6084188
    Abstract: A molded case circuit breaker having separable main contacts and an operating mechanism utilized to cause the separable main contacts to open and close. A trip unit is provided to actuate the operating mechanism in desirable circumstances. The circuit breaker has external terminals which are connectable with an external load and an external power supply. A collar is used to interconnect the circuit breaker terminals with the load and power supply. The terminal collar in this case is non-symmetrical. The non-symmetrical collar provides two functions: the first function is that the path of electrical continently between adjacent collars is enlarged for higher voltage applications because of the non-symmetrical nature of each collar; secondly, the circuit breaker case has a seat therein which has the same cross-section as the non-symmetrical collar, so that the collar can only be inserted therein in one cross-sectional orientation.
