Abstract: The turret of a military vehicle such as a tank is locked in a predetermined position released from this position for installation in another position. The turret has a plurality of holes formed therein arranged in a circular configuration. A pair of lock pins are removably fitted within an adjacent pair of the holes. A single rod is pivotally connected to the lock pins with an operating handle pivotally attached to the rod. Retaining rings are installed on the ends of the rod to retain the lock pins on the rod. The lock pins are angled away from each other and slide on the rod to permit their free entry into adjacent holes. Movement of the handle in a first direction drives the lock pins into adjacent turret holes while movement in the opposite direction withdraws the lock pins from the holes for installation in another pair of holes to change the positioning of the turret.

Abstract: A ratchet buckle has a mandrel around which a strap for securing cargo or the like is wound. A handle assembly is connected to the mandrel through ratchet wheels and is manually driven up and down to tighten the strap. The handle assembly is divided into an outer section, which is manually driven up and down, and an inner section, which is connected to the mandrel. The two sections are connected together so that the driving of the outer section effects driving of the inner section. A spring operates to urge detents on the inner section into the ratchet wheels. Torsion springs are connected between the inner and outer handle sections. The inner and outer sections as well as the torsion springs are supported on a bolt and interconnected by lugs on one section and slots in the other section, which are driven together by spring washers.

Abstract: A beam for supporting a removable second deck for carrying cargo in a vehicle such as a truck trailer is supported between a pair of opposing tracks on opposite sides of the vehicle. The track has slots formed therein to which the beam is attached. The beam has an end foot on each end. Each foot has a keeper pivotally mounted thereon, the keeper being used to removably attach the foot to the slot. The foot has a notch formed in its bottom surface which engages the bottom edge of the slot. The keeper is spring urged against the foot portion to bring the top portions of the keeper and foot into abutment against each other so that the top of the keeper is in abutment against the top edge of the slot, thereby retaining the foot and keeper in the slot. The foot portion and keeper can be withdrawn from the slot by manually moving the keeper away from the foot against the spring tension.

Abstract: A central tube has a rectangular cross section and is attached to an end piece which abuts against a wall of a compartment or the side of an object to be held in place. The other end of the central tube is telescopically fitted within a second rectangular tube. One surface of the central tube is ratcheted and a handle operated ratchet drive mechanism is mounted on the end of the second tube towards the end piece. The second tube is telescopically fitted within a third tube having a rectangular cross section. The remote end of the third tube is fixedly attached to a second end piece which abuts against either a compartment wall or an object to be held in place. The second tube is joined to the third tube at any one of three extension positions of the third bar relative to the second bar thereby setting the jack bar at a predetermined length. This length can then be increased to hold the cargo in position by actuating the ratchet mechanism.

Abstract: A buckle which is used to removably fasten two pieces of webbing, strap or the like together requires two distinct actions for its opening and thus is “double locking.” A latch member is pivotally supported on a frame by means of a support shaft. A first strap end is fixedly attached to one end of the frame. A second strap end to be attached to the first strap end is removably attached to one end of an adjuster member. The other end of the adjuster member is T-shaped. The frame has a pair of opposing ledge portions which extend opposite the base portion of the frame, opposing slots being formed between these portions. The top of the “T” of the adjuster member fits into the slots to retain the adjuster member to the frame when tension is placed on the second strap end portion thereby providing a first locking action. The latch member has a detent formed thereon which engages a detent on the end of the ledge portion of the frame.

Abstract: A wheel chock is formed from a bar which is bent to form opposing bottom arms; a first pair of opposing side arms which run above the bottom arms and are slightly upturned therefrom: a second pair of opposing side arms which run upwardly from the first pair of side arms; and cross arms forming a top portion which runs between the second pair of side arms. A base plate is attached to the bottom arms, this base plate having studs attached thereto and extending from the bottom thereof. The studs fit into a track fixedly attached to the floor of a transporting vehicle which may be an aircraft or a truck. A central plunger latching member which is spring loaded also extends from the bottom of the base plate and latches the plate to the track. The chock can thus be installed in and removed from the track merely by manually positioning the latching member.

Abstract: A beam assembly is formed from a hollow beam member which has a pair of slidable channel units installed therein and extend from the opposite ends thereof. The ends of the channel units have guide shoes forming latching assemblies pivotally supported thereon, each guide shoe having a spring loaded lock key mounted pivotally mounted thereon. A pair of tracks are spaced from each other in opposing relationship by a distance equal to the longitudinal extent of the beam member. The tracks have a plurality of aligned apertures and C-shaped runners running along their longitudinal extent. The lock keys of the beam member each has a pair of fingers extending therefrom which fit into a pair of adjacent track apertures. The fingers may be locked in place in the opposing track apertures by the spring action of their associated springs and may be withdrawn from the apertures by way of a tab formed thereon.
