  • Patent number: 4005628
    Abstract: A head piece, for grasping by a musician, having a stem joined thereto, the stem having elongated teeth which are formed thereon and disposed radially with respect to the longitudinal axis of the stem and head piece. A ratchet body having a bore therethrough is placed over a spindle, and the spindle is threaded into the head piece such that the spindle and head piece are rotatable as a unit. The ratchet body has elongated teeth formed thereon which are radially disposed about the bore of the ratchet body and which mesh with the teeth formed on the stem. The meshing teeth allow rotation of the head piece and spindle in one direction only with respect to the ratchet body, thereby causing a string of a musical instrument attached to the spindle to be wound about the spindle and secured in a taut condition.

  • Patent number: 3991647
    Abstract: A method and apparatus for connecting hairs to a bow of a type including a drilled bore of a novel configuration and orientation in one end of the bow. A helical member fits over the ends of a plurality of hairs to thereby clamp such hairs together. The helical member and the one end of the hairs are then positioned in the bore and such structure is held securely in the bore by the pressure caused by the tautness of the hair when stretched and connected to the other end of the bow.
