Distilling and Sterilizing Apparatus. lieated in both, the chambers, 8 and 10, and casing, 10, are merged as they pass into the pipe, 20. At the junction of the pipe, 20, there is provided a two-way valve 18, and an outlet pipe, 28, leading from the opposite side to the pipe, 20, whereby the turning of the valve 18, by the handle, 19, will introduce the water from the heater directly into the pipe, 20, or pipe, 28. The pipe, 28, may be utilized as a mere overflow pipe for the drawing oft of hot water for culinary or other purposes. It may, however, be connected to the distilling and sterilizing apparatus shown in Figure 2. In the drawing Figure 2, the complete plant or arrangement of the heater distilling and sterilizing plants is shown in vertical section. The heater as he rein shown is varied slightly in its construction, the inlet pipe, -3, in its con¬ struction is shown as leading into the casing, lb, directly and not into the lowermost chamber, 8, as shown in Figure 1. The water entering the lowermost chamber is introduced from the upper portion of the chamber, lb, into a down pipe, 33, at the lower end of which it is introduced into the lower chamber, 8. Further the upper chamber, 10, delivers the hot water or steam by means of a pipe, 34, into a tank, 35, having the upper wall conical or dome shaped and from it extends the pipe, 3b, leading to the worm, 37, contained in the water tank, 38, of the distilling apparatus. By means of this construction the water entering by the pipe, 5, may be used to produce steam in the chambers, 8 and 10, and deliver the same into the tank, 35, to be carried therefrom by the pipe, 3(5, and recondensed as distilled water in the coil, 37, and delivered by it into the tank, 39, as distilled water. The tank, 39, has an overflow pipe, 40, connecting it with the larger tank, 41, by means of this arrangement of the tanks 39 and 41, the hereinbefore mentioned purpose of having two tanks of dir-tilled water is carried out. In many surgical operations it is necessary that distilled waters of different temperatures should be obtained. By this arrangement the water in, 41, may be maintained at a mean or low temperature, while the water contained in tank, 39, may be raised in temperature. For this purpose the pipe, 42, is employed connecting as it does with the pipe, 3b, as the same leaves the heater and entering to near the bottom of the tank, 39. By this arrangement fresh highly heated steam may be immediately introduced into the water contained in the tank, 39, and thereby raise the temperature of the water rapidly and without affecting the temperature of the water contained in the tank, 41. Both the tanks, 39 and 41, are provided with draw-off ispigots, 43. In many instances I employ a filter, 44, through which the water entering into the tank, 39, passes to prevent the introduction of any germ which may be prevented by filtration. By means of the spigot, 45, which is introduced into the cham¬ ber, 35, wherein the heated steam is introduced directly from the chambers, 8. and 10, I may draw either steam or exceedingly hot water Mounted upon the pipe, 42, I place a small chamber or cabinet having suit¬ able construction for containing surgical instruments to be sterilized. This cabinet, 4b, is connected by a short pipe, 47, with the pipe, 42, and the steam is introduced directly into the cabinet, 4b, by the valve, 48, which is of the construction known as “ two-way,” and by which the steam is diverted from tin1 tank, 39. and introduced directly into the cabinet, 4b. Connected with the pipe, 3b, is a suitable steam gauge, 49, used to show the pressure of steam on the apparatus. Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what 1 claim is: — 1.
