The frame has an outer arm which extends parallel to the transverse axis of the ladder and outwardly from both of its sides. The arm is provided with two or more contacting surfaces which make contact with the stationary object which supports the ladder.

  • Publication number: 20140027136
    Abstract: The weed remover has an elongated shaft provided with three or more prongs extending downwardly from its lower end. The prongs are arranged in a circle and are rotated by a handle at the top of the shaft. The prongs extend through openings in a plate which is slidable vertically between upper and lower positions. At the upper position, the prongs are exposed so that as they rotate, they function as an auger to make a circular groove in the ground surrounding a weed so that it can be pulled out. After the weed is removed, earth which adheres to the prongs as they rotate is removed by causing the plate to slide downward to the lower position. As the plate does so, it scrapes off earth which adheres to the prongs.
