\VILLIAM PORTERFIELD CUTLER, OF BALTIMORE, MARYLAND.

SAIL.

EPECIFIC'A'IION forming part of Letters Patent No. 397,589, dated February '12, 18823.

Application filed September 6, 1888. gerial No. 284,702i (N0 model) To all whom, it may concern.-

Be it known that I, WILLIAM PORTE'RFIELD CUTLER, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Sails, of which the following is a specification.

My invention relates to sails, particularly to the j ib-sails of sailingwessels. Heretofore, usually, the head and foot-bias parts of this class of sails have been united at their ends by a lap-seam, at the outer end of which scam the elew was secured, and the sail was formed of strips of canvas which extended in parallel widths diagonally across the sail from the foot or bottom to the head or top of the same. The bias sections of canvas forming the head and foot portions of such sails were so out that the breadths or strips forming them extended in a parallel direction with the leech and foot ropes. Subsequently jib-sails were formed by making the sail in a single section or piece on a bias, so that the ribs or lengths of canvas composing the sail were short and extended diagonally across the sail along its entire length from head or stay rope to leech and from the head or stay rope to the footrope. In addition to thus making the sail on a bias, are-enforcing bias-cut piece or gusset was seen red transversely across the widest or middle portion of the sail, extending 011 each side from the elew to the head or stay rope. Parting of the sail. along the seams extending transversely of the sail to the elew often occurs, in which case the sail is rendered useless. Injury to the j ib-sails of a vessel usually occurs at a time when the vessel under full headway, and frequently during a gale, when repairs of this nature cannotbe judiciously attempted.

The object of my invention is to so form the sails that the defects above mentioned will be obviated, as will be hereinafter more fully described.

In the drawings, Figure 1 a view of a jibsail constructed in accordance with my iniprovenients, and Fig. 2 is a view of the gusset or strengthening-strip.

In carrying out my invention I form the applied to other forms oi sailsof two parts,

A and B, which parts A B are formed of widths or strips, 0 and I), of cloth, the seams of which run in reverse or diverging directions from the middle line of the bolt-rope II and completed sail to the leech-rope E and foot-rope F.

The portions A B of the sail are united at their wider ends by a double seam, and in additi on to this double seam a gusset or stren gtliening-piece, I, is employed and extends on both sides of the sail from the elew to the middle of the head or stay rope, the clew being secured to the sail after the gusset I has been stitched to place in the usual manner.

In the prior constructions of this class of sails, where the longest cloths and scams were employed at and near the widest part of the sail, I use conqmraiively the shortest cloths or strips, and consequently shorter seams. Further, by my construction I greatly reduce the bias upon the stay or head rope, the wider ends of the portions receiving a considerable portion of the bias, thereby rendering the sail less liable to stretch out of proportion in hoisting the sail or during the pitching of the ship. Besides these advantages, my construction presents more bias on the leech and foot,

where the sail must give more or less in order to make a perfectsetting sail.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, isv A reversible diagonal out twopart sail formed of widths or strips of cloth, 0 and D, the seams of which run in reverse or divergin g directions from the middle line of the boltrope II or, completed sail to the leech-rope E and foot-rope .F of the sail, the diverging seams in the respective portions of the sail being parallel, as set forth.

In testimony whereof I at'fix in y signature in presence of two witnesses.
