CONDENSER Specification of Letters Patent.
Patented Sept. 36 19143).
Application filed June 25, 1918. Serial No. 241,729.
To all whom it may concern:
Be it known that T, JAMES J. BAJDA, a citizen of the United States, residing at Island, count of Queens, and State of w York, have invented certain new and useful Improvements in Condensers, of which the following is a specification. v
The invention relates to a condenser of general application and specifically relates to a glass reflux condenser which can be se cured by means of an air-tight connection with the supporting receiver.
The primary object of the invention is to provide a simple and inexpensive form of condenser which will quickly and economically condense the hot vapors received therein and with the least possible destructive action upon the condenser when made of frangible material.
Tn devices of this character it is usual to admit the hot gases at the relatively cold portion of the cooling chamber and to allow the condensed liquid to collect in the inner tube until overbalancing pressures therein cause the liquid to spurt back into the receiver. This Spurting of relatively cool liquid against the hot; sides of the condenser tends to rupture the same especially where these devices were made of glass or similar frangible material.
The invention contemplates a construction which contains an adapter designed to be inserted in the stopper of the receiver and so designed that the hot gases from the receiver are conducted from the adapter exteriorly of the cooling chamber and into an inner condensing tube at the relatively hot portion of the cooling chamber. The invention also contemplates the installation of a liquid trap between the condensing tube and the receiver which trap is open to the external air pressure through a feed tube shut off from the receiver by means of the trap.
Various other objects and advantages of the invention will be in part obvious from an inspection of the accompanying drawings and in part will be more fully set forth in the following particular description of one form of mechanism embodying my invention, and the invention also consists in certain new and novel features of construction and combination of parts hereinafter set forth and claimed.
Referring to the accompanying drawing:
The figure is a view in vertical section of the upper portion of a receiver, showing a preferred embodiment of theinvention attached thereto and with the cooling chamberand adapter shown in section axially thereof.
In the drawings, there is shown the upper portion 10 of a receiver which may be the usual boiling flask employed in laboratory condensing operations. The receiver is fitted with a stopper 11 in which is supported the condenser constituting the subject-matter of this invention.
The condensed includes a relatively large jacket 12, the lower portion of which is reduced to form a tubular adapter 13 fitted within the stopper 11. The jacket has a closed upper end 14 and the adapter is constricted at the junction of the jacket therewith by means of an inner tube centering ring 15 for a purpose hereinafter described. This ring defines the lower end of a water cooling chamber 16 positioned above the adapter 13. The cooling chamber is provided with a cold water intake nipple 17 and a warmed water discharging nipple 18 as is usual in devices of this character.
The condenser is provided with an inner tube 19, the upper portion of which constitutes a bifurcated Y-tube 20. One arm of this Y-tube leads upwardly and axially through the cooling chamber and through the upper end 14: to form a feed tube 21. The upper end of this feed tube is enlarged to form a funnel 22 by means of which liquid may be introduced through the condenser and into the receiver 10. The other bifurcation of the Y-tube constitutes a condenser tube and in the illustrated device is in the form of a coil 23, the upper end of which leads out through the top 14% of the cooling chamber. This upper end of the coil is connected to the tubular adapter 13 by means of a bypass pipe 24 positioned exteriorly of the cooling chamber and coacting with the adapter to constitute a hot gas conduit from the receiver 10 to the upper or relatively hot end of the coil 23. The stem of the Y-tube is bent back twice upon itself to form an 8-shaped liquid trap 25. The discharge end of the trap leads throughthe centering ring 15 and through the adapter 13 to constitute a drip tube 26 adapted to lead the condensates from the trap through the adapter and stopper 11 back into the receiver 10.
In operation and assuming that cold water is passing through the cooling chamber as indicated by the arrows, it will be understood that the lower portion of the cooling chamber is at lower temperatures than I the upper portion. The gases generated in the receiver pass through the gas conduit formed by the adapt-er 13 and bypass 24 and are led therefrom into the upper end of the condenser tube or coil. The vapors are condensed in the coil and the condensates flow into the trap 25 eventually filling the U of the trap as indicated in the drawings. Any high gas pressure in the gas conduit will merely have a tendency to disturb the balanced relation of the condensed liquid in the trap but this trap will at all times shut off the outside air from the receiver, for atmospheric pressure will be maintained on the trap through the open feed tube 21.
This feed tube may also be utilized to replenish the liquid in the receiver and facilitates a quiet flow of liquid from the trap into the receiver.
By means of a device of this character there is provided a compact arrangement which can be supported on a receiver. The gases receive an initial air cooling before they are passed into the liquid cooled coil, thus attaining an accelerated cooling action while economizing in the use of water, ice or other refrigerant passed through the cool.- ing chamber. As the hot gases are introduced at the top of the cooling chamber the COOliJlg of the condensates is gradual and sudden temperature changes are minimized.
The device lends itself readily to glass blowing operations so that it can be formed conveniently and economically. While I have shown and described, and have pointed out in the annexed claims, certain novel features of my invention, it will be understood that various omissions, substitutions and changes in the form and details of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the invention.
Having thus described my invention, I
, chamber, the stem portion of the Y-tube being bent back twice upon itself to form an S-trap, one arm of said Y-tube being in the form of a coil having an intake end adjacent the upper end of the cooling chamber and the other arm opening through the top of the cooling chamber to pass liquid into the trap.
