To all whom'z'tma-y c0ncem:-

Be it known that I, Ismon SCHLESINGER, a citizen of the United States, residing at the city of New York, in the borough of Manhattan and State of New York, have invented certain new and useful Improvements in iVashtub-Covers, of which the following is a full, clear, and exact description.

This invention relates to covers constructed of sheet metal and more particularly to covers of a relatively large size, such as are adapted for use with wash-tubs or similar receptacles.

The objects of the invention are to provid a cover of this character which can be easily and cheaply constructed from a minimum number of pieces of sheet metal, which v will not require fastening means such'as bolts, screws or solder to hold the pieces to-- gether, which will possess the requisite thickness and which willb of a strong and rugged construction to withstand the hard usage to which it is subjected in ordinary'use.

\Vith these and other objects in view, the invention consists of a shallow box-like structure of sheet metal which has inwardly-- directed strengthening ribs formed on one face thereof, which ribs are of sutlicient depth to engage the opposite wall so that they not only serve as corrugations to impart lateral rigidity to the cover, but will also maintain the top and bottom walls in spaced relation. More specifically stated, the invention consists of a cover formed from two sheets of metal provided with marginal flanges, which sheets are joined together to form the box-lik structure described the strengthening ribs being stamped in one of the sheets.

.In the accompanying drawings:

Figure 1 shows, in perspective, a washtub provided with a cover constructed in accordance with the principles of the invention, the cover being shown in open position;

Fig. 2 is a sectional view similar to Fig. 1, showing the cover in closed position; and

Fig. 3 is a transverse section through the cover. I

In the drawings, a wash-tub is shown and is indicated 1, which wash-tub is provided with a cover secured to the back strip 2 of the tub by hinges 3.

This cover is constructed in accordance with the principles of the invention and con- Applieation filed January 11, 1917.. Serial No. 141,737.

sists-of tworectangular plates 4 and-f sheet'metal, such as galvanized iron. These plates are provided with marginal flanges 6 and 7, respectively; the flanges 6 of the top plate 4 fitting over and engaging the flanges of the bottom plate 5, while the edges of the flanges 7 rest against the inner surface of the top plate 6, thus holding the plates in spaced relation. The flanges 6 are of greater depth than'theflanges 7 and their free edges 8 are bent over upon and engage the outer surface of the bottom plate 5, the construction described providing a closed shallow box.

Inwardly projecting strengthening ribs 9 are provided in the bottom plate 4:, which strengthening ribs, as will be clear from Fig. 1, do not extend the entire width of the plate, but only occupy an intermediate position so that the portions of the plate -l adjacent its flanges are smooth and flat which permit a smooth joint tobe obtained between the two plates which would be impossible if the entireplate 4 were corrugated. These strengthening ribs or corrugations 9 are of suflicient depth to bear against and engage with the inner surface of the top plate a. The ribs, therefore, not only serve to strengthen the structure by imparting to it lateral rigidity, but also form a rigid connection between the top .and bottom plates which will maintain them in spaced relation and will prevent them from collapsing or from becoming bent.

It will be noted that in making this cover, no fastening means are employed. The bent-over edges 8 need not be fastened to the plate 5 either by soldering or in any other manner, since there is comparatively little strain upon them. Moreover, since these edges rest upon theupper edges of the tub when the cover isin closed position, the pressure upon them will be sufficient to maintain them in engagement with the bottom plate. The simplicity of the construction is obvious, since in forming it, only two pieces of sheet metal are used, which rubber, or other material, may be provided a upon the underface of the cover, as is the fitting over each other and connecting said usual construction. The cover may also be marginal portions together, and integral coated with enamel if it is desired. strengthening ribs formed on one of said I claim: plates projecting inwardly with respect to 5 A cover comprising two plates of sheetthe marginal portions of said plates and en- 15 material having marginal flanges, each of gaging the under-surface of the other of said plates having a fiat marginal portion said plates. adjacent its marginal flanges, the marginal In Witness whereof, I subscribe my sigportions of the two plates being disposed in nature.
