JOHN WADE, OF BOSTON, MASSACH-USETTS.

METHOD OF MAKING AND FURLNG- IN SAILS' FOR SHIPS, l13m.

Specification of Letters Patent No. 101, dated December 6, 18.36.

To all whom it may concern:

Be it known that I, JOHN WADE, of Boston, in the county of Sulolk and State of Massachusetts, have invented a new and useful Method of Making and Taking in 'Sail by Means of a Revolving Yard on which the Sail is Wound Instead of Reeng, which is described as follows, reference beinghad to the annexed drawings of the same,-m`aking 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 of two or more turns o the halyards c, c, around the center of the yard forming a parbuckle-the halyards passing through two shives d, d, and coming down inthe ordinary way, and attached to the rail. The 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 f, in each to admit the yard to pass oosely through, connected together by cross pieces, one of which g, forms eye-bolts for the quarter blocks, another It, forms a roller for the center cloth hereafter described,-a third 11 forms an eyebolt to which are fastened the heels of the studding sail booms, and two apertures 7c, 7c, for the topsail halyards, and a, fourth forms a semicircula-r metallic parrel Z, embracing the mast.

On each end of the yard there is a loosemetallic box, M, vinto which is fastened three eyebolts n, o, p, for the lefts, the brace blocks, the studdlngsail halyard block also for the top gallant studding sail boom- 4parrel, and boxes at the ends of iron y, this box is attached to the end ofv the yard by an iron bolt with a broad head inserted in the end, in which box the yard withthe bolt revolves, the sail inthe center 1s left open at fv, as far as the close reef to -avoid obstruction from the parrel in Winding the sail, which open space is covered by an apron or4 center cloth S, one end being attached to the said, and the other end passed over the roller It, and drawn taut by a line t, rove through a thimble'attache'd to the foot of the sail. i v

One man with this apparatus will be enabled to roll up in one minute three top sails ofa s hip without leavin Ythe deck by slmply letting go .the top-sail alyards; the yard in deseen' ing revolvin the sail upon it, one side ofv t e halyards remainin .fast In making sail vthe halyards are to e simply hauled which causing the yard to revolve in a contrary direction turns off the sail again. By the use of this appa,- ratus. all reef gear is dispensed with.

The invention claimed, and desired to be secured by Letters Patent consists- In the before described method of making and taking in sail without the necessity of reeling, by carrying the yard to revolve by means of the loose parrel, and halyards com-Y bined with the boxes at the ends of the yards, the opening, and apron in the center ofthe sail, also the peculiar construction of the as herein set forth.
