ABSTRACT:
The jack of the present invention is novel in having a stem extending from a body which is spring pressed from a base to engage an element which thereafter is locked in position to prevent the element from deflecting under load. A pair of studs and nuts are provided within the body between the base and stem which when actuated locks the stem in extending position and prevents the deflection of the element. The application of fluid to a piston within the body releases the stem so that the jack can be removed at the end of the operation on the element. The jack prevents a portion of the element which is not rigidly supported to be retained in fixed position against deflection when being operated on.
