JOSEPH L. DIGKENSON, OF HEMPSTEAD, NEW YORK.
IMPROVEMENT IN REEFING FORE-AN D AFT SAILS.
Specification forming part of Letters Patent No. 21 1,712., dated January 28, 1879 application filed December 23, 1878.
To all whom it may concern:
Be it known that I, J osEPH L. DIoKENsoN, of Hernpstead, in'the county of Queens and State of New York, have invented a new and useful Improvement in Beefing Fore-and-Aft Sails, of which the following is a specification Figure 1 is a side view of a fore-and-aft sail to which my improvement has been applied. Fig. 2 is a detail section of the same, taken through the line 00 a, Fig. 1.
Similar letters of reference indicateporrespondin g parts.
The object of this invention is to furnish fore-and-aft sails which shall be so constructed as to save labor and time in reefing, which may be reefed in such a way as to bring the sail into proper shape for a storm-sail, confining the gaff and giving it all the advantages of a try-sail, which shall be a great ad vantage in jibbing or when rolling heavy in a calm, as the gait is secure, and at the same time shall be easier on the sail.
The invention consists in the combination of the reef-brails with the sail, the gaff, and the mast-hoops, for reefing the upper inner corner of the said sail and in the block-jaw a ttached to the upper side of the inner end of the gafl, to rest against the mast and keep the said inner end of the gaff in place when the said gaff is lowered in reefing, as hereinafter fully described.
A is the mast. B is the sail, the lower edge of which is attached to the boom 0 in the usual way. The mast of the sail B is attached to the mast-hoops D, and its upper ner to its inner edge, near i lower inner corner, is attached a row of bulls-ey s, F, through the upper part of which and through bullseyes F, attached to the gaff E, is passed a reef-brail, G, the free end of which is passed through a bulls-eye, F, attached to a hoop,D, through a bulls-eye, F, attached to the inner site sides of the sail B, frongsiisflouter top corgafi E. To the oppoingwhen confining a reef. Through the bullseyes F of the lower part of the diagonal row, and through bulls-eyes F, attached to the hoops D, is passed a reef-brail, H, the free end of which is secured by a racking when confining a reef.
WVith this construction, by slackening the throathalyards and drawing upon the peakhalyards, the gaff E will be brought into the position indicated in dotted lines in Fig. 1, bringing its outer end nearly into line with the top of the mast A and the outer end of the boom C, so that the said gaff will be held firmly. At the same time the reef-brails G H are drawn upon, reeling the upper inner corner of the sail B against the gaff E and the mast A.
The reef-points I are arranged in an inclined line above the lower inner corner of the sail B, so that when the upper and lower reefs are both taken the sail will be brought into the shape of a mutton-leg sail.
To the upper side of the gaff E, near its jaws, is attached a block-jaw, J, to rest against the mast A and keep the lower end of the gaff E in place when the said gaff is lowered. Reefbrails G H are attached to both sides of the sail B, so as to closely confine the reef.
Having thus described my invention, I claim as new and desire to secure by Letters Pat ent- 1. The combination of the reef-brails G H with the sail B, the gaff E, and the masthoops D, for reefing the upper inner corner of the said sail B, substantially as herein shown and described.
2. The block-jaw J, attached to the upper side of the inner end of the gaff E, to rest against the mast A and keep the said inner end of the gaff E in place when the said gaff is lowered in reefing, substantially as herein shown and described.
JOSEPH L. DIOKENSON.
