    Ashes Improvements in Apparatus for Preventing Sea Sickness. hereunto attached a Sheet of explanatory Drawings, in which Fig. 1 is a side elevation of a metal stem, suitable for securing to the deck or cabin floors of a ship, or placing in a socket in the same, with two curved branches pro¬ ceeding therefrom, from one of which a chair depends by the intervention of a flexible rope, whilst to the other a ball-and-socket joint is secured to 5 support a similar chair, of which only part of the framework is shewn; Fig. 2 is a vertical section of a ball-and-socket joint suitable for use in the arrange¬ ment shewn in Fig. 1, or in any suspending system; Fig. 3 is a vertical section of a ball and ring or washer joint, also suitable for any suspending system or arrangement; Fig. 4 is a front elevation of a chair balanced on the 10 top of a pedestal suitable for securing in or to the deck or cabin floors of a ship; and Fig. 5 is a vertical section, drawn on an enlarged scale, of the ball- and-socket joint fitted to and shewn as part of Fig. 4. In Figs. 1, 2, and 3 like letters indicate the same parts, a represents the stem or standard with branches or arms b; c the suspender of rope, to which 15 the rigid framework d of the chair e is attached ; the same letter (d) shews the part of the chair frame coupled to the other branch or arm ; f the ball, and g the socket, with the connections h broken off1; i the ball, and^ the ring or washer with the connections h, also broken off, the lower one termi¬ nating at its upper end in two screwed rods Z, which pass through the ring or 20 washer, and keep it in its place by two screwed nuts m. The ball and socket are shewn fitted and formed in the usual way, and the ball of the ring or washer and ball joint has part thereof cut away, whilst there is a large bearing surface of such ring or washer on the ball. The point of suspension may be from the deck beams, or from any other “ fixed ” part of a ship or 25 other navigable vessel. In Figs. 4 and 5 the same letters indicate like parts. mx represents the pedestal or standard, on the top of which is formed the ball partly surrounded by the socket n, secured under and to the bottom of the chair, of which o is the seat, p the back, and q the legs ; r, the platform for supporting the circular metal rings or washers t, which may be cast or other- 30 wise formed in segments, and fitted together into rings or washers on the platform.* When the ball and ring or washer joint is used in this arrangement, as well as when it is used with or in the suspending system, the bearing surface of the ring or washer may be reduced to, say, a blunt edge, and the ball may be lengthened outwards at the upper end, and somewhat resemble a 35 cone in form. Spiral or other springs attached to the bottom of the chair and to the pedestal or standard might be used, but I have found the weights, when placed as above mentioned, a sufficient balance.
