ABSTRACT:
This invention relates to a manually operated jack which is particularly adapted to hold cargo in place in moving trucks, railroad cars or to store merchandise in warehouses and in other generally similar environments. The cargo holder jack generally involves a hollow pedestal member upon which the operating components of the jack are operatively mounted. The pedestal is mounted on a base or foot element which is pivotally connected thereto. An operating rod is provided which is mounted for reciprocal movement and this operating rod is free of the pedestal so it may reciprocate therein and independently thereof. On the end of the operating rod, which is opposite to the portion thereof which reciprocates within the pedestal, is pivotally mounted a base or foot member. A box-like structure composed of two elements is mounted on the pedestal and operatively mounted therein are the various operating components which are associated with the operating rod to cause reciprocal movement thereof. Projecting from the box-like structure is a manual operating means for causing movement in one direction of the operating rod and further projecting means is provided for maintaining the operating rod in a particular reciprocated position and for releasing the same so that it may reciprocate further into the pedestal. The box-like structure mounts therein means which provides two compartments within said box-like structure.
