    Newtons Improved Surgical Chair Bed. 101, straps, as described before at 92. 102, rods, as 94. 103, hooks, increased in number according to the number of straps. 104, thongs of the hooks (103). Figs. 36, 37, 38, 39, and 40 shew another variation in the construction of the chair bed. 105 is the frame described A, Fig. 1, 2, & 3, without another 5 joint than those uniting the parts of the side with the ends. The inferior end may be cut sloping to the level of the sides, to make by means of a step the descent from the bed easier to the patient. 106, racks similar to 1, Figs. 1, 2, and 3, but nearer to the extremity of the frame* 107, racks in place of L, Figs. 1, 2, 3, with this difference, that these racks may be fixed to the 1 o frame B. These racks, as well as all those designed for the same purpose, may be substituted by thongs or by cords, which being fixed at one end from below the frame B, roll at the other end about the shafts G, G. 108, hori¬ zontal shafts, described G, G, Figs. 1, 2, 3. 109, transverse shafts, described G in the same Figures. 110, upright beams and slides of the racks de- 15 scribed N. Ill, wheels similar to F. 112, pinions like E. 113, standard as S. 114, guides and slides of the racks 107. 115, supports of the transverse shafts (109). 116, transverse bars to give support (instead of the frame B, C, to the mattrasses T, if they are divided only into two parts, and only C if the mattrasses are divided into three parts (see Figs. 33 and 40). 117, toothed 20 segments, similar to H, connected with the frame D, or, according to the Figures 1 and 2, with the frame A, in which they slide. If the toothed seg¬ ment is fixed to the frame D, this frame ought to be united to C in the centre by a hinge, which forms at the same time the pivot or fulcrum of the toothed segment. Only one toothed segment may be sufficient if placed at the centre 25 of the frame D, and that may be substituted by the means described at H. 118, elastic mattrasses. 119, rack similar to L placed at the sides of the frame B. 120, hinges uniting the frame D with the frame C, or the head parts with the centre. Figs. 41 and 42 represent a mode of drawing away the sacking (5, 5, 5), or the inferior sacking from a bed without rubbing against 30 the body of the sick, and without removing him. 121, frame similar to A. 122, sacking described 5, 5, 5. 123, shaft mounted in standards which carry the pullies (124), and is moved by a winch. The cords (125) are wound underneath. 126, pullies adapted to the frame (121), which pass the cords (125). 127, very thin slips made of metal, of wood, or of whalebone. The 35 one of them is placed in the hem of the sacking (5), and the other is taken up by the sacking, which is folded about it. Having thus particularly described various modes of constructing this improved apparatus, I wish it to be understood that I claim all the modes of
