    N° 16,474 A.D. 1890 Date of Application, 16th Oct., IdSO—Accepted, 8th Nov., 1890 COMPLETE SPECIFICATION. Improvements in Invalid Bedsteads, Ambulances, and the like. I, Georgb: Parrott, of Bicester in the County of Oxfordshire, Carriage Builder do hereby declare the nature of this invention and in what manner the same is V to he performed to be particularly described and ascertained in and by the following statement:— 5 My invention relates to improvements in invalid bedsteads, ambulances and the like and has for its object to further perfect the invalid bedstead described in the Specification of my former Letters Patent No. 12,119 dated the 30th of July 1889. My invention consists in providing means whereby a patient may he raised from his bed for the purpose of changing the bed clothes without having to handle him or 10 otherwise interfering with his posture or rest. In carrying my invention into practice 1 provide two iron bars or tubes one on each side of the bedstead formed of two jointed parts and supporting the sheet or blanket upon which the invalid rests. For this purpose the two longitudinal and the upper edges of the said sheet or blanket are covered over so as to form cylindrical tubular 15 sheaths through which are passed suitable rods which can be easily withdrawn th refrom whenever required. Suitable eyelets are formed at regular intervals in the sheet or blankets close to the inner edge of the rods and through them is passed one end of a strap wound around the jointed bars or tubes aforesaid and serving to attach the rods thereto the said straps being furnished with buckles and perforated ends to fasten 29 them in position that is to say allowing of the sheet or blanket being more or less tightened or slackened. These jointed bars or tubes are guided and supported at their free ends by roller bearings forming an integral part of a lifting bar so that the said jointed bars may be raised or lowered at their other ends i.e. the ends nearest to the head of the bedstead. The above mentioned jointed bars or tubes are connected by 25 means of slotted plates and T headed bolts to a frame likewise jointed in the centre and the lower end of which is capable of sliding to and fro upon suitable rollers fixed to the longitudinal bars of the bedstead as described in the Specification of my former Letters Patent, while the same frame is connected to a swivel icperated bv a vertical screw placed at the head of the bedstead and described in the Specification above 30 described. The said frame is further supported by a rod pivotted to a post fixed to the bedstead. The jointed bars or tubes are further provided with a movable sleeve which when pushed over the joint renders the bars rigid such bars being moved with the blanket carrying the invalid in their raised position. The sliding frame is con¬ nected to the jointed bars or tubes aforesaid by means of props the lower ends of 35 which are pivoted to the said frame while their upper ends are enlarged and slotted and engage with a pin fixed to the jointed bars. And in order that my invention may be more fully understood J have shown the same in the accompanying drawings in which Figs. 1, 2, 4 & 5 are side views of my improved invalid bedstead showing respectively 40 the bed in a collapsed or level position the same with the head only raised, the entire bed in a raised position lastly the same with the foot and head raised but bent in the centre. Fig. 3, is an end view of Fig. 1. Fig. 6 is a plan of the sheet or blanket showing its mode of attachment to the 45 jointed bars or tubes. B is my improved bedstead carried on wheels as shown, and the front legs l of which can be folded under when the former has to be wheeled along. P is the rear bed part carrying a collar c at the top which holds the upper part ot the screw S furnished with a handle h at the top and the bottom end ot which rests centrally 50 upon the transverse rail of the head of the bedstead. Upon this screw can move a swivel nut n connected to the upper end l of the sliding trame F jointed at a and the [ Price 6d.j
