1 Claim.

This invention relates to air humidifying devices and more particularly it pertains to that type of device which is suspended from heating units such as radiators and filled with water to supply moisture to the air in a compartment being heated.

All such devices, with which I am familiar,-

have many disadvantages among the most pertinent of which is their tendency'to'spring a 1n leak. This tendency results from the manner in which such devices are constructed.

All such devices as heretofore constructed, with which I am familiar, are formed by placing two sections together with a flange of one overlapping the other and a soldering of the overlapping flanges. As generally constructed these devices have square corners and are therefore more easily subjected to rupture from the impact or-blows received upon the corners and upon their sides particularly in'the location of the soldered joint or seam.

It is an'object of the present invention so to construct a device of the afore-mentioned char acter that it will be sturdy and will withstand impacts resulting from use, without rupture of the joints.

It is a further object of the invention so to construct the device that it will not only be liquid-tight when first manufactured, but will ll maintain said liquid-tight condition throughout use.

It is still a further object of the invention,

7 so to construct the device that it will present an attractive appearance. 1

.3 With the above and other objects in View, reference will be had to the accompanying drawing and the following specification and claim.

In the drawing:

Figure 1 is a fragmentary. diagrammatic view of a radiator illustrating a humidifier constructed in accordance with the present invention, in position thereon, I

Figure 2 is airagmentary plan View on an enlarged scale illustrating one of the corners 3 of the humidifier,

Figure 3 is a distended perspective view illustratingthe two parts or elements from which The section It! is formed from sheet metal and is shaped, preferably by die stamping, to provide a flat wall portion l2 defined on three sides by flanges which are designated I3, I4 and IS in the drawing-and which extend in planes at 5 right angles, or substantially so, with respect to the wall I2. In the stamping of the section II), the corners are rounded as designated by the reference numeral I6 and the free edge of each of the flanges l3, I4 and I 5 and the rounded corners-l5 are bent backwardly upon their respective flanges to form a locking flange H.

The member H is shaped to provide a wall 20 which is corrugated as illustrated. Defining three sides of this corrugated member ll, there 10 are flanges ii, 22 and 23. This member II is likewise formed with rounded corners 24 and each corrugation ends adjacent the flange 22 in an angular end wall 25. Each of the flanges 2|, 22 and 23, as well as the curved corners 24, is formed with locking flanges ZG-Which flanges 26 are bent backwardly upon their respective panels as illustrated.

In assembling the parts, the two elements l0 and I l are placed together'with the locking flanges 26 of the member l l interlocked behind the looking flanges ll of the member l8. With the parts in this position, they are subjected to'a suitable operation, preferably by dies, to crimp the interlocked flanges 26 of the member' H with their respective locking flanges ll of the member [0.

This method of procedure provides a relatively tight joint. between the members ill and H and after it has been thus far completed, the entire article is dipped in a hot galvanizing bath to deposit thereon a galvanized coating such as 30 in the drawing.

As designated by the reference character! the galvanizing bath, when it is deposited upon the article, completely encloses the interlocked joint between the elements I0 and H thus rendering the device water-tight in every respect.

I The device in its finished state presents rounded corners and is thus able to withstand shocks and abuse without rupture, to a far greater extent than is possible in these devices as ordinarily constructed. y

In use, the device is suspended from a radiator with the corrugated wall of the element ll fitting between the coils of the radiator. The suspending means consists of two hooked members ll] which are removably associated with the device by engagement of hooked ends, not shown, with struck out ears 4| in the conventional manner.

In its completed state the device is in the form of a receptacle for waterQand in its operative position is maintained filled with water to supply moisture.

Having thus described the invention what is claimed as new is:

A metallic receptacle of the character described comprising two members one of which is smaller than the other thereby to permit one member to telescope within the other, and said members adapted to be secured together to form the receptacle, each of which members has a single side wall, two end walls and a bottom wall, the bottom wall of each member being connected to its respective end walls through the medium of rounded corners, an inwardly projecting flange extending from the free edge of each of the side walls and the bottom wall of the larger member, and an outwardly extending flange extending from the free edge of each of the side walls and the bottom wall of the smaller member, said inwardly and outwardly projecting flanges being adapted for interlocking engagement when the smaller member is telescoped within the larger member to secure the members together in receptacle forming relation.
