    A.D. 1855 .N° 593. Beds for Invalids. (This Invention received Provisional Protection, but notice to proceed with the application for Letters Patent was not given ivithin the time prescribed by the Act.) PROVISIONAL SPECIFICATION left by John Walter Cawley Wren at the Office of the Commissioners of Patents, with his Petition, on the 16 th March 1855. I, John Walter Cawley Wren, of Tottenham Court Road, in the County 5 of Middlesex, Iron Bedstead Manufacturer, do hereby declare the nature of the said Invention for “ An Improved Construction op Invalid Bed ” to be as follows:— The object of this Invention is to permit of the bed of an invalid being made up, and of a bed pan being applied and removed, without disturbing the 10 recumbent position of the patient. This I effect by attaching to the ordinary bedstead frame a rectangular frame of a corresponding size, which carries a loose sacking, and is provided with a suitable opening to admit of the application of the pan. This frame I attach to the bedstead by two or more pairs of parallel levers jointed to the sides of the frames. The levers 15 at the foot end of the bed I extend downwards, and connect together by a cross bar, which serves as a treadle to raise the sacking frame. In order to raise the patient, and permit of the removal of the feather bed or mattress from beneath the sacking frame, or the application of the bed pan, it will only be necessary for the nurse to press with her foot upon the treadle, 20 and the sacking frame will rise.
