  • Patent number: 4038960
    Abstract: An arrow holder including a bifurcated end cooperating with a bow side or arrow rest to continuously hold an arrow in emplacement under virtually every condition including while a bow and strung arrow are being carried about in a non-shooting position, while an arrow is being drawn to a fully-drawn position, and while an arrow is being held in a fully-drawn position. Upon release of an arrow, forward movement of the arrow operates to break the cooperation between the bifurcated end and bow side or arrow rest and release an arrow for free flight.

  • Patent number: 3999673
    Abstract: A boat loader including a boom and an elongate traverse arm pivotally connected to the boom. A dolly bar carried on and for movement along the length of the traverse arm includes means for attachment to a boat. According to a preferred embodiment, a U-shaped boom is pivotally connected by the legs of the U to the rear bumper of a vehicle such as a camper or trailer. The length of the legs is slightly greater than the distance from the bumper to the top of the vehicle. The traverse arm is pivotally connected to the boom base midway between the legs and a spring is connected between the boom and traverse arm to normally maintain the traverse arm as a somewhat parallel extension of the traverse arm but which yields to permit pivoting of the traverse arm.

  • Patent number: 3955837
    Abstract: A latch including a handle operative only in response to a grasp-like pull. In a preferred embodiment, the handle comprises a rod bent into a general C-shape to provide a pair of ends. The handle is pivotally mounted. Operation of the handle pivots a first handle end in an arc to move a latch bolt approximately parallel to the chord of said first handle arc to move the latch bolt from an engagement to a disengagement position. The second end of the handle normally closely abuts the latch casing to preclude operation of the handle by a push.
