WARREN c. cHoATE, or WASHINGTON, 4@DISTRICT or COLUMBIA.

MODE or FORMING AND RIGGINQTHE sArLs'oE SQUARE-EIGGED VEssELs.

Specification of Letters Patent N o. 3,54?, dated April 17, 1844.

Be it known that I, WARREN C. CHoATE, of the city of Washington and District of Colu1nbia,.have invented a. new and `Im-` proved Mode of Cutting, Fitting, and Rig ging Sails to SquareRigged Vessels; and I do hereby declarethatthe followingis a tfull, clear, and exact description thereof,

reference being had to the accompanying drawings, which form a part of this specifi cation, in" whichl t Figure `1,is a drawing of the frontof the sails, &c.; Fig. 2,`after side.

The construction is as follows: The yards are furnished with round iron rods i (a) which extend from the slings of each `yard outward on both sides to the sheave holes for the topsail sheets or top gallant sheets near the ends, of the yard arm; these rods are denominated `jack yards; `they are secured `to the yard in front thereof, at the ends by iron `bands (Z9) which are put around the yards and have a goose neck (c) see Fig. 8 (detached) projecting from theln to which said jack yards are fastened at a sufficient distance from the yard to permit the ringsl or hanks, to `which the sail is bent, to run out `and in freely upon them. The rings or hanksare in number suflicient to bend the sailto and sustain it when` spread; to each of the inner goose necks (c) which holdthe inner` ends of the jack yards, is fastened the upper end of a jack stay (d) which runs down parallel with the mast,

those for the fore and main sail being' set up to ring bolts (e) on the deck or they can be shifted forward. There is an iron band ('f) fitted around snugly to the cheeks of the lower mast between the tops, and trusses; from this band an arin (g) projects on each side ofthe rnast, out forward over the lower yards far enough to clear the top; the end of each arm is formed into an eye through which` the topsail jack stay (cZ) passes. It isthen carried back under the top and through another ring or leader (71,)

` at the rnast,.and from thence down on deck;

this jack stay may be set taut by a two or three fold pulley. The lower ends of the top gallant jack stay (cl2) can be set up to an eye bolt (i) on a band around the top ina-st, between the toplnast cross trees and the sheavehole for the topsail type. On all the jack stays are rings or hanks for bind ing the sail to, similar to the manner employed on the jack yard.

`By the above, it will be seen that all the sails are in two parts, the starboard and lart board halves of the sail being entirely independent of each other. The head of each `sail is bent onto the rings or hanks on the jackyard which run outand in thereon; an

outhauler (7c) is bent to the outer head cringle (c) and runs "through a block (l) on the outer end of the yard arm and thence through a block (m) near the center of the yard, from which it descends to the deck; by this the sail is hauled out; an inhauler (n) is also bent to the outer head cringle and runs through the rings or hanks on the jackyard, and thence down on deck by which the head of the sail is hauled in to the mast, assisted by brails (o) and the sail is hauled in and furled like a trysail or spanker.

p I use but one reef in the topsails, which is `the close or storm reef; an inner reef pendant (79) is made fast tothe inner reef cringle (g) and running up to the yard near the slings passing through a leader (79)` is brought down to the deck; an outer` reef pendant (r) is made fast to the outer reef cringle (r) andruns up through a block or sheave hole at the end ofthe yard then in through a sister block (s) in the topmast rigging and thence down on deck; two reef ropes (t) are also attached at equal distances on the reef band (u) which run up to the yard, and then in to the rim of the top, and thence down on deck, these reef ropes haul the reef band snug up and along the yard. p

If the topsail yard is on the cap,and the reef cringles are hauled up, and out, by the reef pendants, and the reef band hauled snug up to the yard, you have an excellent reef in a heavy storni; by this method you have two close reefed topsails, z'. e. .a start board and a larboard,.either of which can be taken in, or set, With the greatest safety Without interfering with the other.

What I claim as my invention and desire to secure by Letters Patent isl. Constructing the sails for square rigged Vessels in two separate parts, the starboard and larboard halves being entirely independent of each other.

2. I also claim the combination of the 10 jackyards and rings and out, and in haulers,

with the yards of Vessels constructed and arranged in the manner and for the purpose herein set forth.

3. I also claim in Combination with the above, What I denominate a jackstay for the 15 inner leach of the sail to traverse on as herein described.
