    Kottusch’s Improved Collapsable Ambulance Stretcher.____ Fig 4 is a plan of Fig 3. Figs 5, 6 and 7 are separate illustrations of a lazvtong section showing the formation of this and the other parts of the frame. The stretcher frame consists of a number of jointed cross-frames 1 each of which is made up of two u-j shaped angularly bent bars connected at the centre 5 with each other by movable joints and to the side standards 2 or 3 by the pivots 4. The four side standards 2 of the two end cross-frames and the side standards 3 of the inner cross-frames have an angular cross section (see Tig 4). The bars of the cross-frames 1 are jointed at one side of the standards whilst the lazy tong sections 6 (constituting the sides of the stretcher) are jointed by means j 0 of pins 5 to the other side. These lazytong sections 6 are mutually movable on the pivot pins 7. The cross-frames 1 are connected with one another by the jointed links 8 which consist of flat steel bars and these bars are connected together by the pivots 9 and one bar of each link carries a stop pin 10 which rests against the Id other bar when the lateral lazytong sections 6 are fully extended. The ends of the lazytong sections are guided by steel tongues 11 which are secured to the lower pins 5 (see Fig 3) and move in lateral guides 12 fitted to the side standards 3. When drawing out the cross-frames and thereby extending the lazytong sections 6 the steel tongues 11 work in the guides of the standards which 20 are thereby always retained at equal distances apart from one another so that the canvas 14 is stretched uniformly taut. The rings 13 of the canvas are hooked on to the hooks 15 of the side standards 2. The side standards 2 of the two end frames instead of having a guide for the steel tongues are each provided with a slot 16 (Fig 3) for guiding the stop pin 17 25 of the last lazytong section. The side standards 2 of the two end frames are provided with handles 19 which are movable on the pin 18 and are used for the purpose of drawing out and carrying the stretcher. These handles have an angular form so that they may be folded up alongside of the rails 2 when the stretcher is collapsed (see 3() Fig 2). When opening out and lifting the stretcher the hook 20 catches against a stop bolt 21 (Fig 3) so that the handles 19 cannot be raised beyond the proper position. The side standards 2 of the stretcher end shown at Figs 3 and 4, which is the end where the head of the wounded person lies, have eyes 22 (wanting on the 35 other end frame which is not shown) in each of which is carried a rod 23 jointed, at this end, to the last lazytong section 6 at the bottom pin 17. This rod 23 is of such length that, when the stretcher is being drawn out, it projects a little at the top (Figs 1 and 3) where it is provided with a hook 24 into which may be inserted the ring 25 of a fold or flap 26 formed in or on the stretcher canvas 14 40 at its end. By fastening the rings 25 to the hooks 24 the flap is directed upwards at a slant from the rest of the horizontally stretched canvas and thus forms a raised support for the head of the wounded or sick person. As each rod 23 is connected with the lazytong section 6 it moves back when the stretcher is being folded together which is a necessary arrangement in order 43 to admit of the stretcher being folded up when not in use as shown in Fig 2. When the stretcher has to be folded together after use the rings 13 and 25 of the stretcher canvas 14 and the head rest 26 are unhooked and the cross-frames consisting of the parts 1 and 2 and 1 and 3 are pushed towards each other. On the handles 19 being released these return into position through their own weight. .‘0 The side standards 2 and 3 of all the frames are then turned round in the direction of the arrows into the position shown in dotted lines at Fig 1 so that they rest inside tlieu-j shaped bars 1 which are then folded up towards each other as shown in Fig. 2. All the movable parts then rest inside the bars 1 which form a box-like frame and the parts are thus protected as far as possible against 53 knocks, etc, during transport. All the parts of the stretcher, with the exception of the steel bars 8 and
