    Abstract: A grapple for use in an overshot has a tension ring with a reduced helix diameter. However, the helix diameter is not reduced on either sides of the control finger slot to allow the grapple to remain in contact with the control. In the alternative, a composite helix member may be utilized. Another embodiment comprises the inclusion of expansion blades on the inner diameter ("ID") of the tension ring which allow the grapple to expand substantially before the fish reaches the segments. Another embodiment provides for a control with an offset finger to allow the guide thread ID to be smaller than the bowl helix major ID. Yet another embodiment provides a spiral grapple having grooves along its axis to provide the ability to catch a larger range of fish.

    Abstract translation: 用于过冲的抓斗具有螺旋直径减小的张力环。 然而，螺旋直径在控制指槽的任一侧不减小，以允许抓斗保持与控制接触。 在替代方案中，可以使用复合螺旋构件。 另一个实施例包括在张力环的内径（“ID”）上包括膨胀叶片，其允许抓钩在鱼到达节段之前基本上膨胀。 另一实施例提供了具有偏移手指的控制以允许引导线ID小于碗螺旋主要ID。 另一个实施例提供一种具有沿其轴线的凹槽的螺旋抓钩，以提供捕获较大范围的鱼的能力。

    Abstract: Disclosed is an improved spear head overshot. The spear head overshot is particularly useful as part of a cable-guided fishing assembly. The spear head overshot essentially comprises one or more pivot lugs, the pivot lugs comprising jaw sections and release point sections, an actuator slide, a wave spring, a pivot mandrel, a screw attached to the pivot mandrel, and a compression spring threaded over the screw. In operation, a spear head is inserted into the spear head overshot until the spear head passes the jaw sections of the pivot lugs, at which time the spear head is locked into place. To release the spear head, the release point sections of the pivot lugs are manually forced inward. Simultaneously, the jaw sections of the pivot lugs are forced outward, thereby allowing the spear head to be removed from the spear head overshot. In a cable-guided fishing operation, this process can be repeated as often as necessary.

    Abstract: A cable hanger for use in a cable-guided fishing operation is disclosed. The disclosed invention provides a cable hanger in which a specially-shaped hanger body is connected to a handle having a cable groove running through it. The cable groove allows for the centerline of a cable to run through the centerline of the handle, thereby allowing for a straight-line pull to be exerted on the cable through the cable hanger. The specially-shaped hanger body is operatively connected to a specially-shaped body cover by a plurality of links. In this way, the hanger body and cover form a "clamshell" arrangement in which the cover can rotate from an open position to a closed position around the cable. When in the closed position, the cover and body are bolted together along the side of the cover and body opposite the links. The hanger body and cover are designed such that the cable rests closer to the links rather than in the center of the hanger body such that the moment arm between the bolts and the cable is increased, thereby increasing the amount of clamping force that can be provided by the bolts.
