  • Patent number: 3999244
    Abstract: A rake for raising and combing the pile of a rug, carpet or the like having a head and an elongated handle attached thereto. The head has a plurality of prongs arranged along an edge opposite said handle in at least two spaced, parallel rows with the individual prongs for each row arranged in alternating fashion. The head of the rake and the prongs are formed in a unitary, one-piece molded construction. The cantilever, double row arrangement of the prongs allows the downward force of the prongs to be essentially equal with the first row of prongs providing a raising effect on the pile with the following row combing the pile. The cross-section of the prongs is curved in a convexo-concave configuration which blends into the head to provide reinforcing and additional strength in the prongs.
