SAIL.

SPECIFICATION forming part of Letters Patent No. 721,286, dated February 24, 1903.

Application filed December 15, 1902. Serial-No. 135,358-. (No model.)

To all whom it may concern.

Be it known that I, JOEL COUCH, a citizen of the United States, residing at Clayton, in

the county of Jefferson and State of New York, have invented certain new and useful Improvements in Sails; and I do 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 had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in sails for boats; and it consists in the provision of a series of sections which are connected together and having corresponding endsleft free or open 'and somewhat baggy to give the sail more driving power and in the provision of springs or other elastic material connecting the gaff with the mast, whereby the former may be allowed to sway when a strong pufi of wind strikes the sail, thereby relieving the sail and holding same firmly against the wind.

The invention consists, further, in the provision of a sectional sail connectedtoa boom, mast, and gafi, said boom being hinged to a yoke secured to the mast, whereby the boom and mast are caused to rotate together or rock' on the lower pivotal end of the mast.

The invention consists,further,in the novel construction, combination, and adaptation of parts, as will be hereinafter more fully described in detail and then illustrated inthe accompanying drawings.

My invention is clearly illustrated in the accompanying drawings, in which- V Figure l is a perspective view of my improved sail; and Fig. 2 is a cross-section of a mast, showing boom connection in plan.

Reference now being had to the details of the drawings by letter, A designates the mast of the sail, having a pivotal pin A at its lower end, and A is a band or yoke which passes about the mast and is securely fastened thereto by means of a bolt a. The boom B is pivotally mounted ona pin B,'which is held in.

apertures in the ends of said 'yoke, as shown.

The sail proper is made up of a series of sections 0, which are connected at corresponding ends to vertically-disposed ropes or tapes D, which extend between the gaff and boom. each section of the sail are connected to the The opposite longitudinal edges of intermediate the free end of the section and the adjacent end of another section, which is fastened to a rope or tape D. Each free end of a sail-section is left baggy, as illustrated,

-in order to give more drive or push to the sailfthe open spaces between the sections being provided for the purpose of allowing the sail to be instantly relieved of dead wind. v

Fastened to the cross-bar L, which is supported by the mast, are the springs N, connected at corresponding ends to the gaff at points N. These springs are provided for the purpose of allowing the sail to give slightly under excessive pressure and to hold the sail against the wind. From the foregoing it will be observed tha by the provision of a sail made in accordance with my invention the sections will be relieved instantly of deadwind and the sail will move with the mast, the gafi allowed to yield, and same kept parallel under normal conditions with the boom. A sail as described is moredurahle than the ordinary sail made up of a single piece of canvas and has more driving-power, as the free ends of the sections being wider than their other ends will sag when the wind strikes same.

Having thus described my invention, what I claim to be new, and desire to secure by Letters Patent, is-

1. A sail made up of a series of sections, each of which has a free baggy edge intersecting pockets to which the fixed edges of the sections are connected, a rotatable mast, a boom to which said sail-sections are connected, and which boom is mounted to move with the mast, as set forth.

2. A sail made up of a series of sections, each of which has a free edge which is wider than its opposite fixed end,.a rotatable mast, a yoke secured thereto, and a boom to which said sail-sections are connected, said boom a gaff having yielding connections with said the mast, a gaff, and springs connecting same mast, as set forth. with said cross-piece, as set forth. in 3. A sail made up of a series of sections In testimony whereof I hereunto aifix my each section having a corresponding free signature in presence of two witnesses.
