A hinged can assembly contains the bag and is guided along a track as the bag is filled and forcibly moved off the stretcher, presenting the filled bag to an operator who removes it and seals the bag.

  • Patent number: 4258828
    Abstract: A folding ladder entirely contained within a U-shaped channel is mounted in a sailboat mast and can be folded and stowed in a flush position, avoiding protruding surfaces on the circumference of the mast. A sliding bar is contained within the U-shaped channel containing a plurality of bracket protrusions which support a swivel pin which in turn support a brace bar connected to a foot bar. One end of the foot bar is fixed to the wall of the U-shaped channel. When the slide bar is moved downward the movement of the brace bar attached to the bracket protrusions extends each step bar forming a series of triangularly supported ladder steps.
