Abstract:
A bar clamp has a slide bar supporting a movable jaw assembly. The slide bar is supported in a fixed jaw assembly. The fixed jaw assembly includes a drive mechanism for moving the slide bar relative to the fixed jaw assembly. Mechanisms for expanding the capacity of the bar clamp including the use of straps and two slide bars. Specialized jaws are provided where the jaws may be removable from the jaw assemblies. Additional clamping jaws are provided in addition to the movable and fixed jaw assemblies for varying the clamping force applied to a workpiece.
Abstract:
Compact tube and pipe expanders and flaring tools requiring reduced actuation force by a user. A flaring tool includes a flaring block and a yoke clampable to the flaring block by a clamping mechanism. The yoke includes a housing having a threaded release portion movable between a first position and a second position. A flaring cone of the yoke has a tapered flaring surface adapted to engage an internal surface of a tube and deform at least the engaged portion of the tube against the flaring block into a flared condition. A threaded feed screw is operatively coupleable to the flaring cone to move the flaring cone into engagement with the internal surface of the tube to deform it. The tool has a handle to rotate the feed screw.
Abstract:
In a device and method for taking temperature readings on an HVAC system, a first probe is connectable in thermal communication with the HVAC system for taking a first temperature reading thereof. A second probe is connectable in thermal communication with the HVAC system for taking a second temperature reading thereof that is independent of the first temperature reading. A digital display is connectable to the first and second probes for displaying the first and second temperature readings.
