Abstract: A hollow handle portion and a hollow barrel portion communicate with each other in a hollow housing. A first detent in the barrel portion has a first relationship for retaining a chalk in the barrel portion and a second relationship for releasing the chalk from the barrel portion. The detent is operable to the first and second relationships by a control member externally disposed on the barrel portion. A rotatable reel and a second detent are disposed in the handle portion. The second detent has a first relationship for preventing the reel from rotating and a second relationship for providing for the reel rotation. The second detent is operable to the first and second relationships by a second control member externally disposed on the handle portion. A string wound on the reel extends at a free end through an opening in the handle portion to a position external of the handle portion.

Abstract: The portable clamp is used, for example, in making repairs to a product, such as a snowboard. The repair volume location of the snowboard is reworked to prepare this repair volume, i.e. a damaged portion of the product, to receive repairing materials. After their placement, a pressure distribution plate of this portable clamp is positioned over, and generally beyond, the repair volume location. Then a bottom clamp bar and a top clamp bar are positioned, respectively, under and over the snowboard. These clamp bars are thereafter drawn together by using the preliminary clamping fastener assemblies located at their respective ends. Then final clamping fastener assemblies, threadably positioned in the top clamp bar, in the central portion thereof, are tightened to continue the distribution of clamping forces to the pressure distribution plate.
