  • Patent number: 5235958
    Abstract: A mounting plate affixes to the vertical riser of a conventional bow. A two-way compression spring extends frontwardly from the mounting plate. A hook member with a downwardly protruding hook on one end and a protruding nub on the other end is rotatably and extensibly connected to the mounting plate by the spring. A catch protrudes frontwardly from the plate and has a rearwardly inclined upper surface. In an arrow holding position, the nub is engaged with the catch and the hook holds the shaft of the arrow. When the arrow head is drawn back, the hook member is pivoted rearwardly to release the nub from the catch allowing the hook member to return to a retracted position. An elastic cylinder may be substituted for the spring.

  • Patent number: 4662346
    Abstract: An arrow holder is disclosed which, when properly used with a conventional bow, allows an archer to laterally load an arrow onto an arrow rest or other support surface on the bow, to laterally confine the loaded arrow such that accidental separation of the arrow from the bow is prevented, and to repeatedly move the arrow longitudinally on the support surface of the bow. The arrow holder includes a plurality of prongs at least one of which is movable between an open position in which the arrow may be laterally loaded onto the support surface and a closed position in which a loaded arrow is laterally confined. Means for adjusting the position of the prongs, means for minimizing contact between the arrow and the arrow holder, and means for biasing the prongs to the closed position are also disclosed.

  • Patent number: 4008510
    Abstract: A fish scaler having a housing with front input opening, a rearwardly declining bottom ramp, and a scaling rotor journalled within the housing. A series of adjacently positioned flexible scaling arms are secured intermediate their ends to and extend radially from the rotor axle. The scaling arms are of rubber-nylon composition and have a pair of laterally spaced extension fingers at one end and a middle extension finger at the opposite end which carry transverse scaling teeth. The teeth arc through a continuous lateral width when the scaling rotor is rotated. The bottom ramp is pivotably mounted within the housing and is spring biased toward the scaling rotor for varying the distance between the ramp and the scaling rotor. The ramp has a hinged extension platform extending forwardly of the input opening.
