Scissors jack

摘要

A scissors jack which has channel link members formed with slots which can be placed over rivets in the jack which have previously been staked in the base or the cap without the channel or link members. The invention relates in an improved jack which can be assembled quicker and easier since holes do not have to be formed in the channel members and the rivets inserted through such holes. The slots formed in the links are such that the links can be placed on the rivets and then rotated and then the free ends of the links are connected together with pivot pins and trunions during which time the links are rotated which locks the links to the rivets in the base and the cap so as to prevent the links from being withdrawn from the base or the cap.
