US Patent:
55270778, Jun 18, 1996
Filed:
Dec 30, 1994
Appl. No.:
8/366758
Inventors:
Mina Bickar - Aberdeen WA
International Classification:
A01D 1106
US Classification:
294 52
Abstract:
An attachment for converting a pitchfork into a combination pitchfork and rake. The attachment comprises a rake head having a plurality of apertures to receive the tines of a pitchfork, along which it is movable between a retracted and an extended position, and a linear array of rake prongs that depend from the rake bar. In a preferred embodiment, associated with each prong is a clevis attached to the rake bar to which the prong is pivotally mounted for free rotation about a horizontal axis during forward-directed scooping motions of the pitchfork along a ground surface when the attachment is in an extended position; during rear-directed, raking motions of the pitchfork, however, a lower portion of a front wall of the clevis permits rotation of the prong only up to a vertical position. Accordingly, the attachment provides a single tool capable of rapid and convenient alternation between raking and pitching motions.
