Description
UNITED STATES PATENT OFFICE.
AUSTIN V. M. SPRAGUE, OF ROCHESTER, NEW Y ORK, ASSIGNOR TO THE SPRAGUE-SCHUYLER MANUFACTURING COMPANY, OF NEW JERSEY.
STERILIZING APPARATUS.
SPECIFICATION forming part of Letters Patent No. 509,560, dated November 28, 1893.
Application filed August 27, 1892. Serial No. 444,273. (No modeLl To all whom it may concern.-
Be'it known that I, AUSTIN V. M. SPRAGUE, a resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Sterilizing Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.
My improvement relates to sterilizing apparatus used in surgery, and consists of a construction hereinafter described and particularly pointed out.
In the accompanying drawings: Figure 1 is an elevation, partially in section showing two tanks and a connecting system of pipes. Fig. 2 is a plan View of an inner heating drum of one of the tanks.
Each tank is provided with a steam heating drum 6, consisting of an annular shell which stands on the bottom of the tank, as shown at the right in Fig. 1.
7 is a main steam pipe and 8, 8 are branches which connect with the drums 6 of the tanks. The main steam pipe and each of its branches are provided with a cook or cut off 4'. By this means the admission of steam to each tank can be regulated independently of the other.
9 is the main discharge pipe for the waters of condensation, and 10, 10 are branches of the same passing through the bottoms of the tanks and connecting with the steam drums 6. Each of these branch pipes is provided with a vent 11 to admit air to fill the vacuum when the steam is cut 0% and also with a cock 4".
12, 12 are over-flow nozzles at the top of the tanks and 13 a common discharge pipe for the same, connected with the nozzles by branches 13. These nozzles are provided with safety valves and with vents 14 which admit air to fill the vacuum when the water from the tanks is withdrawn. The liquid from the tanks is drawn off for use through a tube 15 having branches 16 having cocks 15' and 16 respectively. These vents or air inlet valves 14 are necessary to the suitable'discharge of water from the tanks. They also obviate to a large extent the draft which would otherwise be caused on the inlet pipe 3 by opening a discharge pipe in a tank. And were the pipes 3 and 2 filled with water the withdrawal of water from a tank would tend to suck a portion around cock 4 which effect would be aggravated by pressure from the main were it not for the means provided for excluding water from contact with the cook.
The advantage of the use of two tanks provided with two separate discharges, is that waters of different degrees of heat can be used, either separately or together, thereby greatly enhancing the value of the apparatus. It also enables the water in one tank to be sterilized and cut off from the other and thus made ready for use while the last named tank is being filled and heated. placed at such elevation that the liquid 'will flow by its own gravity with sufficient force around the operating table.
17 are ordinary water gages connected withthe tanks for indicating the height of the water. v
The tanks have preferably a conical bottom which is situated within an annular receptacle 18. A flange 19 on the tank embraces the inner wall of the chamber as indicated. The discharge pipes 16 connect with the lowest point of the tanks for the purpose of entirely discharging the contents when desired or for drawing off sediment.
Theparticular meansof admitting air to the tank and of heating said tank and the particular relative arrangement of parts illustrated are not essential and may be Varied by mechanical skill provided substantially the same principles of construction and operation are employed.
Having thus described my invention, What I clalm, and desire to secure by Letters Patent, is
1. In a sterilizing apparatus, the combination with a tank 1 and with a heater therefor 0t means for admitting air, a water supply pipe 2, a discharge pipe 5 connecting with the said supply pipe, cocks in said supply pipe, one on each side of said discharge pipe 0, thatpart of the supply pipe situated between the upper cock and the discharge pipe being adapted to be entirely drained by said discharge pipe, and a draw-off cock, whereby the tank may be charged with water and the water sterilized by heat and the subsequent entrance of unsterilized water into the tank when a part of its contents are drawn 0ft" effectually obviated; substantially as set forth.
2. In a sterilizing apparatus the combinanation of the tanks 1 provided each with an air-inlet valve normally closed, the steam heating drums, one in each tank, a Water supply pipe having branches with cocks whereby The tanks are one or both tanks may be charged with water,
said pipes communicating with the upper part of the respective tanks, a steam pipe with branches and cocks whereby one or both drums may be charged .with steam, an exhaust pipe with branches provided with airinlet valves and cooks whereby exhaust steam may be conveyed from either or both drums, draw-oft cocks whereby the tanks may be one or both emptied at will and devices to obviate the introduction of unsterilized water, all substantially as set forth, whereby the tanks and heaters may be used to sterilize water either alternately or simultaneously and whereby such water may be drawn off 1n like manner.
3. In combination a tank for sterilizing water having a conical bottom surrounded by a flange tightlysecured to the tank wall above its lower end, an outlet at its lowest point, an annular supporting receptacle to receive said lower end of the tank wall, the supporting receptacle having a vertical wall within the tank wall and immediately belowthe flange of the conical bottom whereby the bottom is directly supported, a steam drum situated in the tank and steam supply and exhaust pipes passing through said bottom within the annular support and communicating with the drum; substantially as set forth.
4. In asterilizing apparatus, the combination with the tanks 1, 1, of the over-flownozzles 12 each provided with a safety valve, the discharge pipe 13 connected with botho'f said nozzles by branches 13 and the vents 14 for admitting air to the tank to supply the vacuum when the water is drawn off; substantially as set forth.
In testimony whereof I have signed this specification in the presenoeof two subscrib ing witnesses.
AUSTIN v. M. SPRAGUE.
