  • Patent number: 4272206
    Abstract: An ink pen is provided which is comprised of an outer rotating and sliding body which fits comfortably, overriding an inner ink containing cartridge. The outer body slides with respect to the inner cartridge when rotated with respect thereto. Rotation of the outer body with respect to the inner cartridge causes the cartridge to retract within the outer body, thus protecting the pocket of an individual upon placement of the pen in such a position when the pen is not in use. Inadvertent placement of the ink pen into a shirt pocket, for example, when the pen is in the writing position, is prevented by means of a projecting clip guard which catches on the outer portion of the pocket, thus preventing the pen from entry into the pocket when it is in its writing position.

  • Patent number: 4048791
    Abstract: A lawn mower of the sickle-bar type having an elongated straight double-edged blade mounted at either end by a planetary mount producing in the horizontal plane a generally laterally reciprocating motion combined with an orbital motion creating cutting forces in both directions with the double-edged blade. The basic support wheels, handle and blade mounting and driving system are so mounted to allow one of the cutting sides or edges of the blade to be used for usual lawn mowing operation, which side is located well within and under and centrally to the basic mower structure, and the other, opposite cutting side to be used for trimming close to walls, trees, etc., which side is located at and moves past the end of the basic mower structure. The handle is reversible from one side to the other to allow the operator to move to and push from the appropriate side, depending on whether mowing or trimming operation is desired.
