c is a small chain or cord attached to the sliding arm G by means of the button I). The

chain 0 passes up through the eye-headed bolt d, with the ring 0 at the upper end of the chain.

The bent arm F is used to elevate objects on or near the ground. When elevated sufiiciently high by the bent arm F, the object is then taken by the horizontal arm G and raised to the required position.

The object of the chain c is to raise or lower the arm G to any required position.

The spring-catch D will hold the lover or handle E in a fixed position.

Having now fully described my invention,

what I claim, and desire to secure by Letters Patent, is

1. The bent and curved arm F and the horizontal arm G, both sliding on the vertical shaft 0, substantially as shown and described, and for the purposesv set forth.

2. Thechain 0, attached to the horizontal arm G, and passing through the eye at, attached to the upper end of the shaft 0, in combination with the bent and curved arm F and the horizontal arm G, substantially as shown and described, and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 19th day of July, 1881.
