TRUMAN (INARAMORE, OF WILLISTON, VERMONT.

RAILROADR AIL AND TIE ELEVATOR AND LlFTlNG-JACK.

SPECIFICATION forming part of Letters Patent No. 276,452, dated April 24, 1883.

Application filed October 6, 1882. (No model.)

To all whom it may concern:

Be it known that I, TRUMAN G. NARAMORE, acitizen of theUnited States of America, residing at Williston, in the county of (Jhittenden and State of Vermont, have invented certain new and useful Improvements in Railroad Tie and Rail Elevators and Lifting-Jacks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of specification.

My invention relates to improvements in devices i'or raising and sustaining heavy bodies.

It consists of a gearwheel, to which a pinion is so attached that its teeth shall mesh directly with those of a rack-bar, so that by the revolution of the gear-wheel by means of a lever-socket pinion the rack-bar is moved vertically at the will of the operator. The entire mechanism is composed of few and simple parts so directly combined as to concentrate the greatest power in the cheapest and most durable manner.

Figures 1 and 2 are side elevations taken from opposite sides.

A represents a gear-wheel, to which is attached the pinion B, so arranged as to revolve upon the shaft 0, journaled near the top of the metallic standard D, which is attached to and stands firmly upon the broad bottom or foot E.

F is a spring dog or pawl designed to control the movement of the gear-wheel A and take the strain of the lift.

G is a handle to the standard D, for the purpose of moving the same more readily. The standard D is so constructed as to allow the rack-bar H to slide vertically within its sides, and between it and the pinion B, and, being corrugated on the side next to the pinion B, it is readily moved vertically by the meshing with it of the teeth of the pinion. The strap I serves to hold it in place. Its upper end, J, is flattened to sustain any weight which may be placed upon it, while a foot or projection,

k, on its lower end is adapted to lift heavy bodies of any kind. The gear-wheel A is revolved by my improved lever-socket pinion, whose mechanism is more particularly described in United States Letters Patent, dated August 15, 1882, and numbered 262,819.

It will be seen that my device can be as readily used to raise, to push, and to sustain heavy bodies of any description, Whenever it can be placed so that they may be made to bear upon the top J or foot K of the rack-bar H. Inasmuch as the revolution of the gearwheel A, caused by working the lever M, the teeth of the pinion B meshing directly with those of the rack-bar H, forces the latter to rise or fall to the extent desired, at the same time its movement can be at any moment arrested and securely held by means of the dog or pawl F, which controls the movement of the gear-wheel A.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

The combination, in a lifting-jack, of the standard, the toothed bar H, the operatingwheel A, pinion B, dog F, connecting-links, and an operating-lever, M, having a toothed socket secured to its end and pivoted between the ends of the links, substantially as shown and described. h

In testimony whereof I do affix my signature in presence of two witnesses.

TRUMAN G. NARAMDRE.
