Letters Patent No. 99,671, dated February 8, 1870.

IMPROVEMENT IN SHIPPING AND UNSHIPPING--HOOKS- The Schedule referred to in these Letters Patent and making part of the'same.

To all whom it may concern Know ye that I, NOAH HAVERMALE, of Canton, in the county of Fulton, and State of Illinois, have in.- rented a new and useful Shipping and Unshipping- Hook, for hoisting heavy weights, and instantly dropping them at any desired elevation; and I do hereby' declare that the following is a full, clear, and exact description' of the construction and operation ot' the same, reference being vhad to the annexed drawings, making a part of this specification.

"lhe nature ol' my invention consists iin so arranging and attaching a sen'es of levers to a draught-bar, connected to the power, and on which hangs the resistance, that the weight may be easily attached and discharged at will.

'.lo enable others skilled in the art to make and use my invention, I will describe its construction and operation.

0f suitable metal, of proper size and strength, I make the draught-bar A, having an eye in the upper end, to receive a hook, B, coupling it to the power.

About three inches from the top a stationary arm,

0, is fixed to the side of the bar, at aright angle, and

having a pulley,'D, near its outer end.

Directly under this arm is E, a mortised projection ofthe bar, and the lower end of A is widened on the same side, and ymortised to receive the lever-hook F, pinned therein, and which passes through to the rear 1hr enough to receive the ring G, attached to the weight or resistance H.

The front end of the leverF enters and is pinned to a slotted or mortised end of the jointed lever I, whose upper end is secured in the mortise at E.

A set-screw, J, working in the draught-bar, becomes a bearing for the jointed lever I, when the machine is raising a weight.

hastened to the jointed lever is a cord, K, which ,at the highest elevation.

of bar.

The machine is so made, that when the power and weight are coupled, as shown in the drawing, the back end of' the lever F inclines toward the draught-bar, and the `jointed lever I bears inwardand rests on the screw J.

`It' this machine is to raise a heavy weight, such as a pile-driver hammer, the hook B is inserted, and the lever I placed in Vthe ring of the hammer. As the power is applied, the ring draws toward the draughtbar, because the upper edge ofthe lever F is a plane, inclined to the bar.

As the weight is drawn up, the cord K rises with the tackle, and is long enough to reach to the ground By-drawing on theeordK, so that the outer angles of I become acute, the weight at once throws up the lever F, (as shown by red lii1es,) and unships itself.

This unshipping can be do'ne at any desired height of hammen'by pulling the cord K. lf the height of elevation is determined, the weight is unshipped at that point, by tying the cord K, at the proper length, to the frame which supports the main line and forms' the guides to the hammer.

What I claim as my invention, and desire to secure by Letters Patent, is

The construction, arrangement, and combination oi' the several parts, lettered A, G, D, E, F, I, J, K, and L, each constructed, and arranged, and combined, substantially as hercinbefore set forth, as and for the uses and purposes herein named, and I expressly disclaim' all other parts and uses.

NOAH HAVERMALE.
