Abstract: A two-component pivotal cable support includes a stationary clamp and a movable cradle mounted on the clamp for supporting a cable wherein the clamp is detachably connected to a stanchion of a boat. The movable cradle, which is pivotally mounted on the clamp, is formed with a curved, open channel portion that is arcuate in side elevation. This channel portion serves as a holder for supporting equipment, or, in the present example, a cable. The cradle includes an open frame with opposite sides joined by a cross member wherein the center of the cradle is exposed and the channel portion of the cradle is supported by perpendicular support posts. These perpendicular support posts can withstand excessive amounts of cable weight. The support posts join the cradle with the cross member midway between the frame opposite ends. A cylindrical spindle is perpendicular to the cradle and downwardly depends from the cradle.

Abstract: A wheel set for boats attached to the transom has a first or non-operative position extending upwardly so as not to interfere with boat operation and a second or operative position where the wheel set is submerged below the surface of the water and makes rollable contact with the beach or land area beneath the boat. Supporting the wheel set is a base or rail fixed on the transom having a movable strut with one end supporting a wheel and the other end of slidably engaging with a track in the rail so that the strut is moved and pivoted from the non-operative position into the operative position. An open slot and pin arrangement is employed for holding one end of the strut in the non-operative position and an elongated closed slot and pin mechanism is provided for pivotally connecting the strut to the base or rail for pivoting into the operative position with the wheel downwardly depending from the boat, while another open slot and pin arrangement maintains the wheel in the operative position.

Abstract: A pivotal mount for an electronic beam generating apparatus, such as radar, loran or the like, is disclosed herein having a fixed member and a rotating member carried on the fixed member. The fixed member includes a clamp for securement onto a vessel's mast and a pair of bearings defining aligned bores. The rotating member includes an L-shaped platform with an outwardly projecting shaft insertably receivable within the bearing bores and further having spaced-apart mounting elements for supporting and securing the electronic beam generating apparatus.

Abstract: An expandable throat plug for use in the recovery of a rocket engine nozzle in an engine assembly is disclosed herein having a deployment device carried on the exterior of the engine assembly including an actuator for advancing an extendable column and an arm normal thereto so that the expandable throat plug can be deployed into and inside the nozzle. A telescoping extension shaft deploys the plug interiorly of the nozzle whereby a pressurized medium expands the plug into conformal engagement with the inner surface of the nozzle to seal and close the throat opening.
