    Newtons Improved Surgical Chair Bed. the head of the racks I, to stop the movement of the shafts 28 and 29, instead of the catch (46). 51, a cross perforating couppling, in order to produce a rotative motion to the shafts (28), instead of adapting a winch. 52, screw. 53, sacking connected with the square frame (39), to which it is fastened by 5 straps an'l hooks to form the back of the arm chair. (54), cords that assist the counterholding bars. The part of the suspended bed in the Nos. 2 and 4, in Fig. 4, and 31, 32, 41, 42, 43, 44, 46, 47, 48, 50, and 51, Fig. 17, may be dispensed with totally or partially as may be judged convenient. Fig. 25, 26, 27, exhibits other modes of adapting the suspended bed, Fig. 4 and 17, to an 10 ordinary bed. 55, frame representing the ordinary bed. 56, exterior frame to which the improvements are to be adapted, which frame is capable of being taken in four parts. It may be composed of the same materials as that described, A, Fig. 1 and 2. 37, horizontal shafts similar to G, G. 58, trans¬ verse shafts corresponding to G. 59, ascending racks same as 1. 60, pinions 15 like E. 61, wheels for the same purpose as F. 62, spur and bevel wheels to give rotatory motion to the shafts 57, and receive impulse from the pinion (63). 64, lateral shafts same as (1), Fig. 4, and (28), Fig. 17. 65, standard similar to S. 66, catch or pall as P. 67, upright beams and slides of the racks, represented at N. 68, screws to press the frame (56) against 20 the frame (55) ; by means of these screws the two frames are connected together in Figs. 28, 29, 30, and 31. 69 is another frame to be employed in adapting a suspended bed to an ordinary bedstead. Its lateral parts may be lengthened by means of the slides 72 and the bars (71), and are elongated or contracted by means of the screws (70), which are at the same time joining 25 screws connecting the sides and ends together. (71), bolts or pins passed through slots. (72), sliding parts for lengthening or shortening the frame. 73, shafts upon which are the two pullies (76). 74, pinions for driving the • wheel 75 ; the axle of this wheel is united with the shafts (73). 76, pullies over which the cords (77) pass. These cords are to draw up the suspended 30 bed. 78, pullies (upper), over which the cords 77 pass. 79, frames to support the pinions (74) and the wheels (75). 80, winch. 81, side rods which passes underneath the shafts (I), Fig. 4, and 28), Fig. 17. At the ends of these side rods are guides in the form of a sw^an’s neck, the forked extremity of which slide on the four columns of the frame (69). The cords (77) are fastened to these 35 sw’ans’ necks. The frame thus composed is intended to sustain the suspended bed. To prevent the parts slipping out, and to render them fast, they are united with the support (82). The suspended bed is exactly the same as it described. Fig. 4 and Fig. 17, only for the toothed segments may be substituted the contrivance shewn in Fig. 31. The whole thus put together may be employed
