METHOD OF MAKING AND FURLING IN SAILS FOR SHIPS, &amp;o.

Specification of Letters Patent No. 101, dated December 6, 1836.

To all whom it may concern:

Be it known that I, John Wade, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useb ful Method of Making and Taking in Sail by Means of a Revolving Yard on which the Sail is Wound Instead of Reefing, which is described as follows, reference being had to * the annexed drawings of the same, making 10 part of this specification.

The nature of my invention consists in winding the sail a, on the yard b, instead of reefing as in the old mode by causing the yard to have a revolving motion by means 15 of two or more turns of the halyards c, c, around the center of the yard forming a parbuckle—the halyards passing through two shives d, d, and coming down in the ordinary way, and attached to the rail. The 20 yard is kept to the mast, and moves up and down against the same by means of an iron parrel in which the yard revolves, this parrel consists of two circular metallic plates e, e, having a round aperture /, in each to * 25 admit the yard to pass loosely through, con- nected together by cross pieces, one of which g, forms eye-bolts for the quarter blocks, another h, forms a roller for the center doth hereafter described,—a third i forms an eye_r 30 bon £₀ which are fastened the heels of the studding sail booms, and two apertures 7c, 7c, * for the topsail halyards, and a fourth fonns a semicircular metallic parrel I, embracing the mast.

³ ® On each end of the yard there is a loose metallic box, M, into which is fastened three eyebolts n, o, p, for the lefts, the ^Y brace blocks, the studding sail halyard block also for the top gallant studding sail boomiron y, this box is attached to the end of the 40 yard by an iron bolt with a broad head inserted in the end, in which box the yard with the bolt revolves, the sail in the center is left open at v, as far as the close reef to avoid obstruction from the parrel in wind- 45 ing the sail, which open space is covered by an apron or. center cloth S, one end being attached to the said, and the other end passed over the roller h, and drawn taut by a line t, rove through a thimble attached to the foot 50 of the sail.

One man with this apparatus will be enabled to roll up in one minute three top sails of a ship without leaving the deck by simply letting go the top-sail halyards; the 55 yard in descending revolving, and winding the sail upon it, one side of the halyards remaining fast. In making sail the halyards are to be simply hauled which causing the yard to revolve in a contrary direction turns 60 off the sail again. By the use of this apparatus. all reef gear is dispensed with.
