proved construction is applied. Fig. 2 is a plan.

Like letters refer to like parts in all the figures.
The center beam on is pivoted iu the middle as usual, but instead of a lever of one piece provided with pivotal holes in the same piece, a lever-socket piece, I), is furnished with the proper series of pivotal holes and a socket into which independent levers of varyin g lengths may all be fitted. The lever proper f may then be shipped or withdrawn at pleasure without interfering at all with the pivotal adjustment of the purchase. The levers are often required to be withdrawn hastily to clear the deck for other purposes, and when the pivotal pins are withdrawn for this purpose much care has to be exercised to replace them in the proper holes to give the required purchase, while with the socket-piece bfitted with all the necessary pivotal holes, the levers may be instantly withdrawn and as quickly re-shipped without interfering with or disturbing the pivotal adjustment, so that no delay for care in the readjustment is required, the pivotal adjustment all the while remaining the same. The usual fulcrum-link c connects the lever- .socket b to the step with the usual pivotal pins. But the step d is furnished with a series of holes for the pivotal pin, corresponding to the similar series in the lever-socket, whereby, when I place the upper end of link 0 nearer the pivotal end of the lever-socket, I am not subjected to the disadvantage of working the link 0 in an inclined position, but can also adjust its lower end in a similar relative position to the lever-socket, and preserve the upright position of its center of oscillation without necessity of changing the pivotal pin in beam to. I can also fold the lever sockets, as shown in Fig. 4, (a very compact and convenient position when not in use,) without remov ingtheendpivotalpin. Thebeamaistobeconnected in the usual manner by shackles to the primary levers or pawl-cases of the windlass-barrcl, for which purpose the holes (1 are provided.
The parts may be constructed of the usual materials-cast or wrought, as may be required.
Claim.
The short lever b when constructed with the lever-socket and the series of pivotal holes,
