The objects of our invention are to enable the stretcher on which a person suffering from an injury or sickness may be laid, to be conveniently and easily placed on the upper platform in an ambulance of the van pattern, and to enable the stretcher on the lower platform of an ambulance to be retained in a horizontal position when the vehicle is on an incline. According to this invention we form the upper platform in an ambulance of the van pattern so that said platform may fold up against the side of the van when not required and when required may be let down into a horizontal position and lowered to the level of the bottom platform or to a convenient position for the purpose of placing a stretcher thereon when it may be again raised and retained at the higher level in the former horizontal position, i or this purpose we hinge the back rail of the upper platform to the upper ends of two metallic standards whose lower ends are pivotted to the lower portion of the side of the van, and placed at a little distance apart; each of said standards moves in a semi¬ circle in a quadrant guard, a hinged rod is connected to and projects from the upper portion of each of the aforesaid vertical standards, the outer end of each rod being attached to the outside rail of the platform. To lower the platform it is pulled towards the rear end of the ambulance and the aforesaid standards lie over within the quadrant guards; the platform will thus project at the end of the vehicle and be at a convenient height to place a stretcher with its occupant thereon: it is then pushed in which causes it to rise to its former level when it is secured by a pin in each of the quadrants and the outer side of the platform is steadied and supported by a rod suspended from the roof and secured by a spring or springs. We provide a hinged extension to the tramway at the bottom of the van, so that a stretcher fitted with wheels may be placed thereon and run into the van; at the inner end of the van we provide a tilting bar on and to which the inner end of the stretcher is placed and secured; by means of an eccentric an attendant can raise the end of the stretcher so as to keep it in a level position when the vehicle is on an incline: If the ambulance is required to carry more than two patients it is constructed of sufficient length to afford space for an attendant at one end of the vehicle. 40 Dated this 4th. day of April 1900.
