A represents a bed-plate of any suitable size, from which rises a'box, B, grooved vertically for the standard O and lever D towork in.
The standard 0 moves perpendicularly up and down in the box B, and on one side, at the uppeneud, is provided withia series of notches, a a, for holding the piece E by means of the bail I) attached to said piece, and inserted or laid in the notches a a.
The lever D is pivoted in the lower portion of the box B, its inner end coming under the standard 0, and on the upper side of the lever is a semicircular projection, G'.
The fulcrum of the lever "D is, as seen, on one side of the center of the circle G, which raises the standard 0, therefore holding the object raised without any assistance.
By raising the lever D the standard 0 is raised, and from the construction of the lever it will be seen that when partially raised the weight of the object assists in raising itself.
