I, Wolf Defries of 147 Houndsditch in the City and County of London E.C., Engineer, do hereby declare the nature of this invention to be as follows :— The object of my invention is to provide a self contained apparatus for 5 disinfection with saturated steam, and the improvements which it embodies are increased simplicity in construction and working, and entire freedom from mechanical risks. The apparatus consists essentially of a boiler preferably partly enclosed by a furnace, upon the top of which is mounted a disinfection chamber, the pressure, in 10 the boiler and in the chamber being controlled by a liquid seal in an adjoining cylinder. The boiler is preferably horizontal, and at its lower part is fitted with a tube having a vertical return terminating at a suitable height above the top of the boiler in a funnel from which the boiler is filled. Alternatively this pipe may be 15 placed in a covered tank provided with a ball-cock or equivalent contrivance, and connected on the one side to any convenient w7ater supply and on the other side to the boiler, at the level of which the tank is placed, the ball valve closing at the normal water-level of the boiler. In the upper part of the steam space in the boiler a tube is fitted leading to the control cylinder hereinafter described, and at 20 one end of the steam space there is another pipe leading to the disinfection chamber and controlled bv a cock or valve. The boiler is fitted with a water gauge, and •/ draw off cock. The disinfection chamber may have any suitable shape, for instance, that of a horizontal cylinder. A screen preferably of tinned copper, extends round its 25 whole inner surface at a small distance from it, apertures or a longitudinal slot being provided at the top. The lower part of the annular space thus made communicates with a tube from the boiler. A hinged door is preferably provided at each end, secured in a suitable manner. The interior of the chamber is fitted with racks, hooks, or other contrivances for carrying the objects to be disinfected, 30 preferably made movable. At the lower part of the chamber at the end opposite to the inlet from the boiler is attached a pipe leading to the upper part of a vertical tube fixed in the control cylinder. This tube is closed at top and fitted w7ith a thermometer. The c} linder is partially filled with water or other suitable fluid, and the open tube 35 from the hoiler extends in it vertically downwards nearly to the bottom, the tube connected w ith the disinfection chamber terminating somewhat higher. A sufficient space is left at the top of the cylinder to accomodate the fluid from, the vertical tubes when they are filled with steam, and an overflow is provided slightly above the level which the fluid then attains. The cylinder may be provided with a 40 cover through which these tubes pass in the upper part of which a chimney pipe may be fitted. Instead of water any suitable fluid, such as mercury or disinfectant solution, may be used. [Price 8d.]
