SKATING-SAIL.

SPECIFICATION forming part of Letters Patent No. 302,517, dated July 22, 188%. Application filed April 28, 1884. (No model.)

do hereby declare thefollowing to be a full,

I which can be readily and conveniently folded sail in position upon the skater.

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. This invention relates to that class of skaters appliances which comprise a sail adapted to be secured to the body of the skater and assist in his propulsion on the ice.

' The object of my invention is to provide a simple and efficient skating-sail and rigging,

into compact form to permit of the transpor tation of the device through crowded thoroughfares, cars, 81c.

In the drawings, Figure 1 is a front elevation of my invention, showing the sails set. Fig. 2 is a rear perspective view showing the Fig. 3 is a detail view in elevation of the top-mast, the top end being in cross-section. Fig. 4 is a detail sectional view showing the lower end of the top-mast in position upon the mainyard. Fig. 5 is a detail perspective view of the central portion of the main-yard. Fig. 6 is a detail end view of the top-sail yard. Fig. 7 is a detail end view of the main-yard. Fig. 8 is a detail view in perspective, illustrating the folding joints of the yards. Fig.9 is a detail perspective view of the connection between'the end of the bracing-strips and the lower corner of the sail. Fig. 10 is a perspective view showing the sail and rigging folded, ready to be rolled. Fig; 11 is a perspective view showing the device rolled in compact form, ready for transportation.

Corresponding parts in all the figures are denoted by the same letters of reference.

Referring to the drawings, A designates the main-yard, which is provided at its center with a circumferential groove, on, preferably formed in a central enlargement upon the yard, so that the outer edges of the said enlargement form circumferential shoulders a a. This yard is adapted to be secured to the back of the skater, at about his shoulders, by means of a cord, B, secured to the center of the yard, preferably by being passed around the yard at the shoulders a, and having its two end portions, 1) Z), passed through the central loop, b, formed in the cord, this fastening being illustrated in Fig. 6 of the drawings. The cord may be secured to the body of the skater in any suitable manner; but the end portions, b, are preferably passed over the shoulders of the skater, as shown in dotted lines, Fig. 2, from whence they are brought down and tied around the waist.

O designates the top-mast, which is provided with abifurcated lower end, preferably formed by a casting, c, that is received by the groove a inthe main-yard. The top-mast is thus supported upon the mainyard, and it carries the topsail yard D by means of a halyard, E, secured centrally to the yard D and passing through an eye, 0, at the top of the top-mast, this eye being preferably formed by a suitable casting. rope or cord, and its end may be secured by winding round a cleat on the top-mast, but it preferably consists of a strap, asshown, provided with a series of botton-holes or perforations, 0, adapted to be engaged over a stud or button, a", projecting from the top-mast. The yards A and D are jointed to adapt them to be folded when the device is out of use, these joints being preferably formed by means of plates F, pivoted in recesses in the adjoining ends of the yards at the joints, sleeves G being provided upon the yards and adapted to slide over the joints, to stiffen and brace the same when the yard is extended. The slid-' ing sleeves maybe provided with a circumferential milled rib, g, to facilitate their adj 11stment, and they are provided with a rightangular end slot, 9, adapted to engage a pin, 9 provided upon the yard to secure the sleeves in position when they are adjusted over the joints. Stop-pins may also be. provided upon the yards to limit the movement of the sleeve.

H designates the sail, which comprises the mainsail and top-sail portions-in one piece,

The halyard may be formed of and is secured to both yards in any suitable manner, the stays h at the top corners of the top-sail yard, as shown at d (Z, while the stays h at the junction of the mainsail and top-sail portions are engaged around circumferential shoulders a formed upon the ends of the mainyard. The sail is disposed in rear of the topmast, and is secured to the rear sides of the yards, so that it will be at the back of the skater when it ,is secured in position.

I I designate two strips, having their lower ends connected to the lower corners of the mainsail, and formed with joints corresponding to those upon the yards. The connection between these strips or rods and the sail is preferably formed byra lap-ring, J, passing through a staple, 2', upon the end of the rod and through eyelets h h in the sail. These strips are adapted to project up in front of the skater, and they are adapted to be conveniently operated by him to brace the mainsail, to enable him to run before the wind, to tack, or to govern the movement of the sail.

In reefing, the top-sail yard is rolled down toward the main-yard, the halyard being passed through one of a central vertical series of eyelets, h*, formed in the top-sail, at each revolution,by which arrangement the halyard will securethe reef without the aid of reefing-points. Generally, however, the top-sail yard will be rolled down to the first series of reefing-points h and secured by the latter in theusual manner. In case of a high wind or inability to manage the top-sail, the top-sail yard can be rolled down to the main-yard, and secured by the reefing-points h justunder thelatter. The sail may be still further reefed by drawing the mainsail portion up until the lowermost series of reefing-points h is brought to the main-yard, when the reef is secured by tying the points around the main-yard.

The operation and advantages of my invention will be readily understood and appreciated.

The device is simple and inexpensive, and is convenient and efficient in operation.

When it is desired to fold the sail for transportation, the bracing rods or strips I Iare disconnected from the sail and folded ,the top-mast is separated from the main-yard, and the ends of the yards are folded over to their central portion to the position shown in Fig. 10. In this position the sail is folded to correspond with the folds of the yards, and the strips I I and top-mast are placed parallel with the yards, as shown, when the whole device may be compactly rolled to the position shown in Fig. 11 and secured by the cord B.

I do not wish to be understood as limiting myself to the construction and arrangement of parts as herein shown and specified, but reserve to myself the right to all such modifications as properly fall within the spirit and scope of my invention.

It is evident that many modifications may be made. Forinstance, the joints of the yards and bracing-strips may be formed by hinges or any other suitable devices; or the yards and strips may telescope to secure their contraction. The lap-ring connecting the bracing-strips and the corner of the sail may be dispensed with, and suitable straps may be secured to the sail and tied through the staple upon the bracing-strip. Under some circumstances the top-sail and top-mast may be en-, tirely dispensed with; or, on the other hand, a

double top-sail may be formed by providing another top-sail yard upon the top-mast.
