UNITED STATES WILLIAM R. SATTERLY, OF SETAUKET, NEW YORK.

REEFING- FOB/E ANI) AFT SAILS.

T o all whom it may concern:

Be it known that I, VJLLIAM R. SATTERLY, of Setauket, in the county of Suiolk and State of New York, have invented a new and useful Improvement in Fore and Aft Sails for Vessels; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1, is a side view of a mast, boom, gaff and sail with my invention applied. Fig. 2, is a. similar View exhibiting only the inner portion of the sail, the outer portion and the gaff being removed. Fig. 3, is a top view of the throat of the gaff.

Similar letters of reference indicate correspending part-s in the several ligures.

To enable others to make and use my invention I will proceed to describe its construction and operation.

A, is the mast; B is the boom; C, the galt;

lD, the throat halyard; and E, t-he peak hal yard, all applied and operating in the usual manner except that the throat of the gai C, has applied to it for the purpose of confining it to the mast, a movable bow E, (Figs. l, and 3,) of iron or other metal, which is connected by a double eye a, c, (Fig. 3) on one side, and by a hook and eye Z), 0, on the other side to permit the gaff to be easily and quickly detached from the mast.

G, and H, are the two triangular portions of the sail the inner portion G, being secured to the boom and the outer portion being secured to the gaii" and the two lit-ting together, as shown in Fig. l, to form a sail of the form commonly used with a boom and gai), and being secured together at their junction by a series of loops d, el, known to mariners as keys 7 which can be all let go by unfastening the one known as the king key shown at 5, in Fig. l. The inner portion Gr, is furnished at its upper corner with a ring e, which is attached to the hook f, on the gait when the two portions of the sail are in use as shown in Fig. l, but which has the throat halyard D, attached when only the portion G, is in use as shown in Fig. 2. The outer portion H, is furnished at its lower corner with a ring 7, to receive the hook g, of the sheet or out hauler h.

When the two portions Gr, II, of the sail are combined as shown in Fig. l, they make a sail which may be considered in all essential respects the same as the sails ordinarily used and handled in the same manner and which might if furnished with points be reefed in the same manner,though I do not think more than one reef will be necessary as the further reduction can be more advantageously effected by taking away the p art II, which is eiiected as follows. The king key at 5, is first unfastened and the gaff and the whole sail then lowered down to the boom. The ga is next disconnected from the mast by unfastening the bow F, and also disconnected from the halyards and the portion I-I, of the sail disconnected from the outhauler. The throat halyard is then attached to the ring e,` and the port-ion Gr, of the sail hauled up as shown in Fig. 2, and the gaff and portion H, may be stowed away till again required. The portion G, of the sail constitutes a very effective and safe trysail and if provided with points may be reduced by reefing it to the boom in the ordinary manner of reducing sails.

This construction of the sail is not intended to dispense with the gafftopsail,which may be applied in the usual manner and in fact it does not necessitate any change in the rig of a vessel, to which it is applied, but a vessel of ordinary rig may have it applied at the mere expense of the new sail or sails or the alteration of the old.

The triangular sail I do not claim as my invention; but

Having thus described my invention, what I claim and desire to secure by Letters Patent is- The combination with and above the triangular sail G of another triangular sail ILI
