Letters Patent No. 108,706, dated October 25., 1870.

IMPROVEMENT |N SQUARE-SAILS FoR edRE-AND-Ar-'r vizssELs.

The Schedule referred to in these Letters Patent and making part of the salma.A

. i To all whom it may concern.-

Figure 2 is va view ofthe square-sail yard with a part of the sail;

Figure 3 is a cross-section ofthe yard; and Figure 4 is a like View, showing a modification.V Similar letters of reference indicate like parts in the several gures;

This invention relates toan improved method of attachinga squaresail to its yard, whereby a half squaresail can be used and changed to either side with-the greatest facility, and the full strength of the yard be retained, as hereinafter explained.

Square-sails are used which runout and-in-witll hoops running on the yard; but as the hoops cannot pass the slings or truss of the yard, a half sail with yard-hoops cannot be used, as l it cannot be changed -over from side to side, and if an iron rod or rope jackstay is used under the yard, without support in the center, all the strain from the 'head of thesail is brought upon the ends of the yard, and it is easily broken. y

I attach a dat irontbar, C, to the lower side of the yard along its entire length. or spread, by means of hutm'ents or studs c, (figs. 2 and 3,) with .wood screws passing through the bar and studs,V the studs being of such length as to support the bar at about half an inch from the yard, and being narrower than the face of thc bar, as shown in'g. 3.

Metallic hanks, D, are placed on the barO, and

the head of the square-sail is'secured to said hanks by robands,'passing through eyes in theshanks or hanging ends of the hanks, as shown in iig. 2. g

rlhese metallic hanks are made izo/embrace -the bar O by claws passing over the opposite sides or edges of the baras seen in iig. 3, and slide longitudinally on the bar G, in place of hoops running'on the yard, when the'sal is set or taken in, and as the bar extends the whole-length ofthe yard, the half sail B can be-runacross from one side to the other,

with the changes of wind, without interfering vwith'.V

the truss E,'and, by this means, thel leeward or idle half ofthe sail is noti necessary, and the square-sail is lighterto handle, and is more snug whenfurled.

Fig. 4 shows a modilication, in which the claws are continuous in the barthat is fastened to the yard,

while T-headed hanks Dareused,with robandeyes in their `hanging parts, as before; butthis construction isless simple than the bar and hanks, as 'shown I do not claim the stationary guides or'ways, and the carriages or jaws sliding thereon; as new in themselves, as they were discovered prior -to my im'fention;l but Having thus described my invention, f

lVhat I claim, and desire to secure by Letters Pateut, is-

The combination ofthe yard A with the traversing half sail B, when the latter is bent thereto by the means described, for the purpose specified. v

v The above specification -of my invention signed by me this 9th day of June, 1870 A. A. ROLLING.A
