SHIPS RIGGING.

SPECIFICATION forming part of Letters IPatent No. 414,631, dated November 5, 1889.

Application filed December 24, 1888. Serial No. 294,526. (No model.)

To all whom zit may concern: the ratline not being free to rotate, the strands Beit known that I, GEORG-E D. COLEMAN, thus exposed are soon worn through, thus a citizen of the United States, residing at rendering the ratline liable to break at this Chicago, in the county of Cook and State of worn place. It is to obviate these objections 55 5 Illinois, have invented a certain new and usethat I have devised my present invention, the

The form first referred My invention relates to rigging, and more to is shown at the right of Figs. 2 and 3 particularly to that portion of the standing and in Fig. fl, and consists of two separable 7 5 25 rigging known as ratlines, and has for its halves c, having formed between them an object to provide means whereby the ratlines aperture C', of a diameter corresponding to may be readily and firmly attached tothe that of the shroud to which it is to be secured. shrouds, kept taut, and prevented from sag- Sharp teethr or projections c are formed on ging and from wearing unequally. the interior of this aperture to engage with 8o 3o To these ends myinvention consists in certhe shroud and hold the clamping devices more tain novel features, which -I will now proceed firmly in position.

In. the structure shown in Figs. l, 2', and 3 this is elected by providing' the end piece D with a ball orsphere d, which its within the corresponding socket c2 ot the clamping-piece and is retained therein, while at the same time it allows free play in all directions at this point. composed of two separate members D and D2. The former of these members has the form of an internally-threaded cup, to which the ball d is connected by a reduced neck d', and into which the other member screws, as shown in Fig. 3. This other .member D2 is apertured longitudinally to receive the end of the ratline B, the said aperture being comparatively small at one end,`as shown at d2, and being enlarged from that point onward, as shown at di. The end of the ratline is provided with lli enlargement, as shown at b, and a coiled spring D3, arranged within the aperture d3, 'abuts at one end against this enlargement, its other end abutting against the shoulder di lat the other end of the recess cl3. The two members D and D2 are of a like external diameter, so that the exterior surface of the end length, and the member D2 is tapered or conical in shape, as shown, so as to present a smooth incline from the surface ot the ratline, instead of an abrupt shoulder.

VThe universal joint connecting the end 'piece of the ratline to the clamping device -inay be constructed in any suitable manner, and 1 have shown in the drawings two modi- 'fied forms of this connection. The first is shown in Fig. 4 of the drawings, in which there is interposed between the clamping vdevice C and end piece D a two-part link or connection F., the two members of which are connected by a swivel-joint e. The end piece D is pivoted to one member of this link, as indicated at e', and the other member of the link is pivoted to the clamping device C, as shown at c2. By this construction a free 'movement in all directions, aswell as freedoin ofrotation of the ratline, is obtained, as in the construction in Figs. l, 2, and 3; butI deem the construction first described preferable, for the reason that it is simpler and stronger and occupies much less space. The second modiiication is shown in Figs. 5 and 6, in which the clamping device C is provided with a pivot pin F, passing horizontally through the same and having a central enlargement or ball f, through which passes' a pivot-pin F', attached to the end piece D.

`This construction allows a free movement in lall directions and forms practically a universal joint, but it has the advantage of not permitting' the ratline to rotate.

The device illustrated in Fig. 7 is employed Y as a substitute for the clamping devices on the intermediate shrouds at and near the upper ends of these latter. At this point the yshrouds approach each other so closely that the clamping devices and end pieces described would occupy almost all the space be tween. the shrouds and render the ratline su- Each end piece D is perluous and useless. vTo overcome this difficulty, I employ at this point only the clamping-pieces on the outer shrouds, employing a The ratline B passes between the yoke and the shroud and rests upon this roller. The object of this devicefis to hold the ratline rmly in position` and prevent its chafing against the shrouds at this point.

The construction which I have just de.

scribed operates to overcome the disadvantages attendant upon theordinary construction in a sufiiciently obvious manner. fThe ratlines may be readily connected -to the shrouds at any desired point and as readily disconnected by meansl of the clamping -devices for that purpose, and when thus connected they are not only rmly held in position, but all danger of displacement, owing to chaing or wear, is entirely done away with. The ratlines may yield to the foot, as does the ordinary ratline; but the spring, D3 will always return them to a taut position, thereby preventing their sagging and preserving a neat appearance. The employment of the universal joint to connect the ratline to the clamping device prevents any danger of wear or breakage at this point,which danger would be present were the connection a rigid one. Moreover, the ratline being free to rotate, the wear is distributed equally over its whole surface, and a much longer service is thereby obtained than is obtained from the ordinary ratline.

It is obvious that various modifications in the details of construction and arrangement of the parts may be made without departing from the principle of my invention, and I therefore do not wish to be understood as limitin g myself strictly tothe precise details hereinbefore described, and shown in the drawings.

Having thus described my invention, what I claim as new, and desire to secure'by Letters Patent, is-` 1. The combinatiomwith the shrouds, of the metallic clamping-pieces mounted thereon, the ratlines, and the metallic end pieces secured to and inclosing the ends of the ratlines and connected to the clamping-pieces, substantially as and for the purposes specified.
