Cleaner Surrounds Tooth Patents (Class 172/607)
  • Patent number: 5152348
    Abstract: A turf spiking tool attachment 10 retrofits turf aerating machines 20 having reciprocating pistons 20 with the turf spiking tool attachments 10 mounted on the free ends of the pistons 20 for motor driven punching and aerification of turf. A flat base plate or punch plate 11 is secured to the free end of a piston. A plurality of spiking tines 13 project from the base plate 11. A stripper plate 12 is formed with a plurality of openings 18 in alignment with the projecting tines 13 of the base plate. The stripper plate 12 is mounted adjacent to the base plate 11 for sliding motion relative to the base plate. Guide elements 15,16 maintain the stripper plate and base plate substantially in parallel alignment. The stripper plate 12 bears against the turf. A stripper spring 17 pushes the stripper plate against the turf, holds the turf in place during retraction of the tines 13, and returns the stripper plate 12 to a starting position.
