    Decamps' Apparatus for Baising a?id Supporting Invalids, Eixed Part.—The fixed part consists of two uprights or head and foot pieces, preferably of round iron or other metal, each composed of three vertical bars, the two ends of which spread apart, bending to an S shape to form the base of the upright, the middle bar remaining vertical. Each of these three bars terminates at its lower part in a tenon pierced 5 with a hole to receive, the middle one a nut bolt, and the two outer ones two longitudinal cross pieces intended to unite the two uprights or head and foot pieces. A horizontal bar placed about 12 inches from the ground strengthens the upright and keeps it in position. The upper horizontal bar uniting the three vertical bars is rounded at the angles. 10 The lower part of the upright is about 39 inches from the ground, and the distance apart of the two outside bars about 28 inches. Three tenons are let into three mortises made vertically in a wooden socket of about 39 inches in length by a thickness of about 4 inches. The two uprights or head and foot pieces are united at their base by two longitudinal cross 15 pieces of rod iron or other metal or material, having a total length of about 7 feet 10 inches, and provided at each end with a screw thread of about 8 inches in length to permit the uprights or head and foot pieces to be brought closer together or be set further apart. These two longi¬ tudinal cross pieces are themselves kept at a proper distance apart by a 20 fiat cross piece bent over at each end into a ring, and this cross piece is kept in the middle of the two longitudinal cross pieces by an adjusting screw at each end. Moveable Part.—This part is composed, 1°, of two bars of rod iron or other suitable metal or material, herein-after termed the main supports 25 or bearings, of about 7 feet 10 inches in length, and each having at both ends a screw thread of about 8 inches in length. 2°, of three cross tie pieces of flat iron, pierced at the end with openings to receive the main supports or bearings; five smaller supplementary supporting bars of a total length of about four feet 3 inches, with screw thread at each end of 30 about 12 inches and which may be shifted when required, are fixed on the tie pieces by two nuts at each end. One of the cross pieces is placed in the middle of the two main supporting bars to keep them at the proper distance apart; the two end cross pieces have on their middle part and directed downwards, an extension or lug pierced with a hole. 35 3°, of six slide rods of round iron or other suitable material, three for each upright or head and foot piece, having a height of about 3 feet
