APPARATUS FOR PURIFYING GAS.

SPECIFICATION forming part of Letters Patent No. 769,713, dated September 13, 1904.

Application filed September 28, 1901. Serial No- 76,305. (No model.)

To (LU whmn it ntay concern.-

Be it known that I, J OSEPH ETIENNE PRE- GARDIEN, a subject of the Emperor of Germany, residing at Kalk, Rhineland, Germany, have invented certain new and useful I mprovements in Gas-PurifyingApparatus, set forth in the following specification.

In the apparatuses forpurifying gas already known, in which single condensing-chambers are connected by means of pipes to form a continuous series, there is the drawback that for cleaning out single chambers the whole series must be put out of use and the manufacture thereby interrupted.

The present invention is for the purpose of enabling single condensing-chambers to be cleaned without interrupting the process. This is effected by inserting in each pipe, connecting two condensing-chambers with each other, a double and single plug, which allows a communication being made between one chamber and the next or shutting off this latter and making connection with a pipe discharging into the main connectingpipe above the plug.

1n the accompanying drawings, Figures 1 to 3 illustrate diagrammatically one constructional form of the invention. Fig. 4 shows another form of construction.

The special construction of my invention may be more clearly followed by reference to the characters on the drawings.

The suitably-cooled condensing-chambers 1 2 3 4 5 are connected in a series by means of outlet-pipes 7), b 6 I), and 5 which are secured in the upper end of each chamber and are connected with a main gas-carrying pipe (I. Extending into each chamber are pipes a (f, (2 (1 and (5, which are connected to the main supply-pipe (Z for conducting the gases into the condensers, wherein are separated the impurities in the gases.

Upon each of the inlet and outlet pipes, just above the top of the condensing-chambers, are dish-shaped extensions 0 to 0", into which are fitted pipe-sections g g, which are greater in cross-section than the ends of the inlet and outlet pipes and adapted to permit of the movement therein of valves h 74/. These pipe-sections g g are hermetically sealed in said extensions or sealing-grooves c to 0 and main supply-pipe (Z connects through them with inlet-pipes a to ai upon the plugs it it being lifted out of their seats. At the upper end of the pipe-sections are inserted pipes f, whose ends are adapted to seat valves 7b. These pipes f are connected by pipes (Z to (Z to the pipe-sections g of the outlet-pipes I) to The valves it h are so arranged by means of chains i i, which are wound around drums a to a, as to be lifted upon the rotation of said drums ofl' their seats upon the upper-ends of the inlet and outlet pipes, which extend into the pipe-sections r g and to close the pipes f, while at the same time opening the inlet and outlet pipes leading to the condensers 1 to 5. By this means gas from themain supply-pipe is admitted to the condensers, or by seating the valves upon the inlet and outlet pipes of one or more condensers communication to said condensers may be closed and the gas flow by pipes (Z to (Z to the other condensing-chambers. In this manner any one of the series of condensing-chambers may be cut out without retarding the process of puriiication.

In Fig. 4 is shown a slightly-modified structure wherein the pipes a to a arejupon the outside of the condensing-chambers, the gases having first to pass through cross-pipe a: when the plug-valves h are in the position shown before being carried through the condensingchamber and through the outlet-pipes to the next of the series. j is a receptacle containing a liquid to form a seal with J and a.

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 I claim is In a gas-purifying apparatus, the combination of a series of condensing-chambers, inlet-pipes communicating therewith, a series of outlet-pipes connected to said chambers, inclined pipes communicating with said inlet and outlet pipes, a series of by-pass pipes connecting said outlet and inlet pipes, a plugvalve, arranged in said outlet and inlet pipes of each condensing-chamber, and means to operate the valves simultaneously, to cut out or in one or more of said chambers of the series, substantially as described.

In Witness whereof lhave hereunto set my hand in presence of two wltnesses.

JOSEPH ETIENNE PREGARDIEN.
