APPARATUS FOR THE ABSORPTION OF MOISTURE AND GASES.

Specification of Letters Patent.

Patented May 2?, lull Application fi led March 1, 1917. Serial No. 151,849.

To all whom it may concern:

Be it known that I, PAUL POETSOHKE, a citizen of the United States, residing at Milford, in the county of Sussex and State of Delaware, have invented certain new and useful Improvements in Apparatus for the Absorption of Moisture and Gases; 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 appertains to make and use the same.

This invention relates to apparatus adapted to be mounted within closed compartments, and especially appertains to a: device which is portable, compact, and composed of cells or chambers for receiving various media whereby gases and moisture may be collected from the air within the closed compartment.

The invention particularly relates to means which may be utilized to absorb moisture and gases that may be present jointly or severally, for instance, in balance cases, static machine cases, scientific and surgical instrument cases, safes, vaults, museum cases, show cases, clock cases, show windows, and other such compartments in which there may be reserved or stored instruments or articles subject to be deteriorated by moisture .or deleterious gases. It is well known that moisture and certain gases effect the tarnishing and corrosion of certain delicate machines of precision, and that static machines are rendered inoperative and inactive because of the humidity of the case in which the machine may be contained, also that tarnishing and corrosion of scientific instruments will occur unless the moisture normally or otherwise present in the atmosphere is removed from the compartment in which these instruments are stored, also that papers stored in vaults or safes become damp and musty and frequently produce mold as a result of moisture, and that moisture in show windows or show cases will often condense upon the glass and even deposit as frost in the presence of lower temperature.

Therefore it is one of the important objects of my present invention to'provide for the absorption of moisture and deleterious or harmful gases which are present in the .air within a chamber and which are conducive to the above named serious injury of the a suitably constructed device involving a basket or container which may be provided with a plurality of independent cells each for containlng a suitable or given medium or agent designed to be effective either for the a removal of moisture or for the absorption of various gases, it being understood that the nature of these agents and media may and will be determined by the nature of the gas which-may be present in the compartment in which the object to be rotected or concealed or covered is dispose With that end in view there is described in ,the following specification and illustrated in the accompanying drawing one embodiment of the invention, in which drawing:

Figure 1 shows a perspective view of the assembled device and as disposed within a compartment a portion of which is shown diagrammatically.

Fig. 2 is a-perspective view of the container or basket for receiving the agents conducive to the absorption of the objectionable moisture and gases, and showing one of its shelves detached.

Fig. 3is a perspective view showing the receiver for the condensed moisture or solutions as discharged from the superposed container.

In its illustrated and simple form herein shown the device comprises a base or supporting member of suitable shape, design, proportion and material, and, as shown, is in the form of a semi-cylindrical trough 2 haying legs 3 whereby it is elevated, and withln the walls of the trough or receiver 2 there are provided suitable shoulders, shelves, or brackets as 4, upon which there may be rested the superimposed container which is adapted to receive the various agents or media which may be utilized to efiect the desired result of condensing the mo1stur'e and ases within the compartment as l) in whic the device may be installed.

The container for the absorptive agents is herein illustrated as composed of a rectangular box or basket-like element 5 of suitable be deposited upon the supporting trough 2 to rest on suitable supporting means as be either punched sheet metal or woven wire as may be desired, the apertures or perforations .of which are sufiiciently small to prevent the outflow of the material which may be contained within the container, and yet provide for the free and spontaneous circulation of the air through the walls of the container into the interior. In the form here shown the container 5 consists of a box-like element of rectangular form adapted to be supported upon the trough 2 and within the container there are provided suitable supporting means as brackets or lugs 6 arranged at suitable elevations and positions in superposed relation so as to support removable vshelves indicated at 7 in Fig. 2, these preferably being of perforated or foraminous material and when arranged upon the respective brackets 66 in a horizontal plane across the container 5 from several independent cells or chambers in which Various agents or media to effect the desired result may be disposed.

For instance, in the lowermost chamber indicated at Abeneath the bottom shelf and above the foraminous or perforated bottom of the container 5, there is disposed any suitable dehydrating agent', as for instance,

granulated calcium chlorid, and in the next chamber above and indicated at B. Fig. 1, there may be provided a charge which has the function of absorbing acid gases, such for instance as an alkaline substance as granulated quick lime, and when there are more chambers provided, as, for instance, in the uppermost chamber C, there'may be provided an agent or medium for absorbing other given or definite gases such, for instance, as removing hydrogen sulfid, in which case cotton or other absorbent material may be charged with a solution of lead acetate. From the above it will be seen that with the present device provided preferably with a container whose walls are substantially wholly perforate and which has a perforate bottom and top, the latter being indicated at 8, and when the various chambers of the container 5 are suitably charged, that with the device installed in a compartment the various active agents within the container will spontaneously act to absorb the moisture and gases from within the container and thereby protect objects against tarnishing or corrosion or becoming inopera tive or inactive by the presence .of deleterious gases.

It is an important feature of the present invention that the device is so constructed and designed that it may be readily arranged within the compartment in which devices are to be protected, and further that the air will be permitted to freely circulate about and into and through the device with a spontaneous action, and further that the various media may be renewed or changed as the occasion may require by the simple removal of the chamber 5 from its supporting trough or receiver 2 and by the removal of the top 8 to expose the interior of the container to permit the removal of the detachable or removable shelves 7. After the device has been in use for a period, any moisture which may be collected in the receiver 2 can be readily discharged therefrom by the simple removal of the superposed container 5 therefrom and the trough may then be readily emptied to discharge the collected solution.

What I claim is:

1. A device for the spontaneous treatment of air, comprising a trough having rests or seats, a box with walls perforated by small apertures and bottom adapted to nest in the top of said trough at the seats, a series of finely perforated shelves insertible in said box to form separate compartments into and out of which air may pass through said walls and bottom, and a perforate closure for the top of the box.

2. A device for the spontaneous treatment of air, comprising, in combination, a moisture receiving trough having an open top, a box for receiving differentreagents, and having its walls," top and bottom perforated with fine apertures, said box nesting in the top of the trough, and detached shelves spaced one above the other in said box for subdividing the chamber to hold separately the different reagents.

In testimony whereof I afiix my signature in presence of two witnesses.
