1n which the ges is forced through a suitable,"

purifying agent.

As heretofore recticed, the ges has been purified by forcing the seine through iron oxid, using for the purpose a plurality of purifying-chambers connected by a syste-rn of valves, so that any one of the chambers could be ont out when necessary to eisen the purifying agpnt. I

It is the o ject of the present invention to provide e puriier in which but a single purificatiomchernber is used and in which means ere provided for reversing the direction of current of the gas, whereby to cleen the {iltering agent Without the necessity of removing it from the chamber or Without the introduction of additional air for this purpose.

The invention will be described in the following speciiicetion, reference being had articulerly to the accompanying drawings, 1n Which- Figure l is en end elevation of e purifier constructed in accordance with the invention. Fig. 2 is e. similar View with the end plete removed. Fig. 3 is a side elevation of the same. Fig. 4 is s. longitudinal section on line 4 4 of Fig. 1, and Fig. 5 is a. horizontal sectional view taken on the plane indicated by the line 5 5 in Fig. 4 and showing the inlet and outlet pipes at the ends of the purier.

Referring to the drawings, the improved purifier comprises a metallic box or casing of any desired sectional contour and size, the end wells of 2 which are provided at diametriceily opposite corners with ports 3 end e, respectively. The ports 3 end 4 of the reV spective end Wells are arranged in reverse order-that is, the port 3 et one end of the casing is directly opposite the port at the opposite end of the casing, though seid ports are respectively arranged at the upper and lower portions of the casing. By thisarrangement the ports 3 are arranged in elinei chamber.

nient transverse the length ol the casing, but et opposite side edges of the respective end Wells, es clearly shown in full end dotted ines in Fig. 2. Within the casing 3` is arranged e grste 5, positioned above the rcspec-tive openings 4, on which grate thc il tering a ent is to be supported, it being understoo that the upper surface of said lneteriel is below the openings 3. The side Walls of the casing are provided with suitable doors which may be of any preferred type,

Yfor sealing the openings, through 'which doors the ltering materiel may be removed or repleced, es desired.

n chamber 7 is provided et each end of the easing l, the chamber et one end being for the inlet of the gases and the chamber at the opposite end for the outlet of the gases, and each chamber is preferably formed by securing Va Well 8 to and spaced frein one of the end Wells of the casing. This chamber is divided by verticelly-erranged

partitions

9 and 10, eech of the partitions extendin transverse the oheinber from the casing enV Well to the well 8. The partitions 9 extend from the upper Wall S of the chamber 7 and terminate above the lower wall thereof, while the partitions 1G are arranged Yalternately with the` partitions 9 and extend frein the lower Well of the ehernber 7 toward the upper Well, terminating a short distance from said upper Well. By this construction the artitions, preferably four in number, divi e the chamber hereinafter termed the feedchernber, into

jive compartments

11, 12, 13, 14, and 15, 'successively 1n communication et opposite ends, providing e tortuous passage transverse the cheinber 7. It will be noted that the respective openingsV 3 end 4 are of practically the full Width of the respective compartments in which they are located and that the partition adjacent Said port closes the compartment in direct communication with the port against the successive compartment Vexcept at the end of the chamber remote ironsV said port. The gas is admitted to the chamber 7 through e pi ie lo, in corn municetion with a source oi supply and opening into the chamber neer the up er edge of the to Well thereof, being pre eri.ebly so locate as to directly coininunicete vitltbe central compartment 13 of the feed- It is understood that as the chamber 7 et the opposite end of the casing is identical With that described the pipe 16 in ICG IOS

TIO

communie-ation therewith will serve as a discharge or service pipe from the purifier.

As described, it ls obvious that the admission of gas through the pipe 16 will cause said to pass into the purifier through the

ports

3 or 4 at the feed end of the purifier and out the ports3 or LL at the opposite end of the purifier. As these respective ports, lunvcver, are positioned above and below the purifying medium, it is obvious that il'l such operation were permitted the gas would not be compelled to traverse the purifying medium at all. 1t has been heretofore proposed to provide a series of complicated valve structures by which the gas may be compelled to travel through the filtering medium in the direction desired; but owing to the complication in structure and. operation of suoli valve mechanisin the results have not been wholly satisfactory. The present invention aims to obviate this difficulty by providing a simple controlling means by which the gas may be directed into the casing through either of the

ports

3 or 4, a similar and sim ultaneously-operating means being located in the exit-chamber of the purifier to close the port reversely located relative to the port openedin the feedchamber, so that the gas is con'ipelled in its traverse of the purifying-casing to pass entirely through the purifying agent. The means to this end comprises a sealing medium, such as water or other liquid, (shown at 17,) in the chamber 7 and in such quantity as, when in the

compartments

13 and 14 or 11 and 12, as the case may be, to seal and close the opening below the respective partitions 9. To control and regulate the posi tion of the sealing medium, the compartments 14 and 12 are in communication through spaced pipes 18 and 1Q, and the respective pipes 19 of each chamber '7 are in communi cation through pipes 20, extending longitudinally of and beneath the casing 1. A suitably-operated transferring device, as a pump 21, is in communication with the pipes 18 and 19 and is adapted in operation to transfer the sealin medium in the respective chambers from t e compartments 13 and 14 to the

compartments

11 and 12, or vice versa. SightA gages 22 of usual type are in communication With the compartments 14 and 12, respectively, enabling the operator to have a visual knowled 1e of the condition of the sealing medium an for another purpose to be later described. In use, assuming that the sealing medium is positioned in the compartments 13 and 14, thereby closing the passage below the partition 9, dividing these compartments and effectively sealing them against each other, this condition being duplicated at the opposite or delivery end of the purifier, the gas admitted through the pipe 16 is thereby compelled to travel into the compartment 12 beneath the partition 9 and up through the compartment 11 and through the port 3.

The co1apartments l1 and 12 of the delivery end ol the casing are in communication in the new positioirof the seal; but as these compartn'lents communicate with the port 4, which is located below the purifyii'ig medium, the gas is con'lpelled to pass wholly through the body of the purifying material in order to .reach the outlet-port. When desiring to reverse. the direction of current of the gas, the pump is operated to transfer the sealing medium to prevent passage of the gas below the partition E), separating the

coinpartments

11 and 12. 1n this condition the gas is compelled to pass through the port 4 on its entrance to the casing 1 and up through the purifying material to the upper port 3 at the outlet end of the casing. A deflecting plate or box 23 is placed inside of the purifyingchamber at each of its ends and adjacent to its bottom to conduct the gas to the reverse side of said chamber, so that it will be necessary for the gas to pass the greatest possible distance diametrically through the oxid on its course to the outlet-port.

As clearly shown in F ig. 5 of the drawings, the dcflector plates or boxes 23 extend transversely of the purifier beneath its false bottom or grate 5, on which the purifying 1nedium is supported, and each of said boxes has its outer end opening into the lower end of one of the compartments 5 and its other open end. terminating a short distance from the opposite side of the purifier, so that the gas must take the longest course from one corner ofthe purilying-chamber to the corner diagonally opposite, as indicated by the arrows in Figs. 4 and 5. By the reversal of the current described I am enabled to clean up the deteriorated purifying agent without removing the material from the box or without introducing air in combination with the gas. No intricate valve mechanism is required for the reverse operation, and the direction of flow of the gas is readily and instantly controlled.

By the use of the sight-gages the operator is enabled to readily determine the condition and position of the sealing medium and to also readily detect the presence of any back pressure incident to an imperfect operation of the device. The box or casing 1 may also be provided with manholes, preferably on top thereof, for use in properly Ventilating the same when making repairs or the like or for the purposes of inspection.

The particular details of construction of the purifier, aside from the features hereinbefore described, are immaterial so far as this invention is described, and I wish it understood that I do not limit myself to any particular size of purifier, shape, or material therefor.

It will also be readily understood that two or more boxes ma r be installed, as may be found desirable. referably two boxes are installed, one being designed as a reserve- ITO ,of said casing being formed With ports, chamssese box, for the reason that eventnaiiy the oXid will become exhausted and unfitted for use and will have to be renewed.
