REEFING SAIL'S.

SPECIFICATION forming part of Letters Patent No. 235,868, dated December 28, 1880.

' Application filed August 23,1879.

To all whom it may concern Be it known that I, JAMES GoNmE, of Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Reeling Sails; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure l is a perspective view. Fig. 2 is a horizontal sectional view, looking down upon the boom. Fig. 3 is avertical sectional View; and Fig. 4 is a detail view, showing, in perspective, the construction of the mast and my improved friction-rollers.

Corresponding parts in the several figures are denoted by like letters of reference.

This invention relates to devices for reefing sails; and it consists in certain improvements therein, which will be hereinafter fully described with reference to the drawings, in which A represents the mast of a vessel; B is the main boom 5 O, the gaff, and D the sail.

The upper and lower edges of the sail are secured, in the usual manner, to the gaff and the boom. The inner edge of the sail is secured to the mast in the manner which will be hereinafter described. The sail isprovided with two parallel horizontal rows of eyelets or openings, E F, and cleats G H, having bearings, each, for a set of pulleys, I J, are attached to the sides of the boom, as shown. Lines K K are attached to the cleat H, passed through the eyelets in the upper row, (second reef,) down the pulleys I I, and attached to the main reefing-line L. Similarly lines M M are attached to the cleat Gr, passed through the openings in the lower row, (first reef,) over the pulleys J J, and attached to the main reefing-line M. Hoisting-lines O P are attached to the gaff and passed through blocks Q, in the usual manner, down to the deck of the vessel.

It has been customary to secure the inner edge of the sail to the mast by hoops secured ing them in said groove.

to the sail and encircling the mast; but this method is clumsy, and often fails to operate satisfactorily; It being especially important, in connection with my invention, that the sail should be easily raised or lowered, I have de vised the improved method of securing it to the mast which 1s fully illustrated in Figs. 2 and 4 of the drawings. By reference to said figures it will be seen that the mast is provided with a vertical groove or recess, R, accommodating several sets of rollers, S S, each set consisting of two rollers secured to the sides of a plate or shank, T, projecting through a vertical slot in a plate, U, secured upon the mast over the groove It, for the purpose of forming a bearing for the rollers and retain- The outer ends of the shanks T are provided with openings, in order that the edge of the sail may be readily attached thereto. A number of sets of rollers, about equal to the number of hoops now employed, may be used.

Instead of the vertical groove or recess R, wooden or metallic guides, suitably secured upon the mast, may beused without changing the spirit of my invention.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation of my invention will be readily understood. It is simple and efficient, and may be constructed at a small expense.

I am aware of patents to J. W. Norcross, dated September 27, 1864, No. 44,445, and J. E. Worthman, dated November, 7, 1871, No. 120,806, and 1 therefore do not wish to be understood as claiming, broadly, anything shown and described in said patents.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States The sail D, having two parallel horizontal rows of eyelet-openings, E F, arranged near the lower end thereof, boom B, having cleats Gr H arranged upon. opposite sides thereof and provided with pulleys I J, lines K M, attached to the cleats H G, passed, respectively, through the eyelet-openin gs E F, over the pulleys I J, and connected to the main reefinglines L N, in combination with the mast, having vertical groove R, slotted plate U, slidhave hereunto set my hand and seal this 20th ing shanks or plates T, having rollers S S, day of August, 1879.
