LAUNDRY TUB Filed April '24, 1940 2 Sheets-Sheet 2 Patented Oct. 5, 1943 UNITED STATES PATENT OFFICE LAUNDRY TUB Emil 0. Dauch, Grosse Pointe Park, Mich.

Application April 24, 1940, Serial No. 331,273

2 Claims. (01. 68-232) sumps and interconnect the drain bushings there- My invention relates to sheet metal tubs, and particularly to tubs of the stationary laundry type having one or a plurality of compartments in which the clothes may be washed and rinsed.

Heretofore stationary types of laundry tubs were usually made of heavy concrete or slate and were quite cumbersome and easily broken. The present invention contemplates the drawing of a sheet of metal to form sump portions of predetermined shape having drain openings and a flanged ledge about the top. A ledge is formed between the sump portions to which a wringer board may be attached and apertures are disposed in the central portion of the rear ledge through which water pipes extend for connection to a faucet which is swingable over either of the sumps. Soap dishes are preferably debossed in the rear ledge between the sump and flanged edge, the latter of which is rolled downwardly and inwardly to provide strength.

Below the central ledge a tie plate is employed which is preferably welded to the bottoms of each of the sump portions to form a rigid construction and provide a shelf on which brushes, soaps and the like may be stored. Leg brackets are attached to the outermost portion of the sump to which legs are threaded so as to be adjustable to regulate the height and the level of the tub. It is within the purview of my invention to provide a die for producing a sump having a continuous flanged edge to provide a single stationary tub or which may have the flanges welded or otherwise secured together to form a tub having a plu- -rality of sumps. In view of the right and left hand arrangement of the two tubs, I preferably mount the drain opening in the center of the bottom sump portion. The junction between the two sumps may be bolted together and trimmed with a suitable molding and a strap may interconnect the sumps in a removable manner so that the tub may be shipped knocked down.

Accordingly, the main objects of my invention are; to provide a tub having a pair of sumps with a brace between the sump portions forming a shelf; to provide brackets on the outer edges of a pair of sumps of a tub to which legs are adjustable mounted; to form a sump having a central drain opening with suitable flanged and rolled edges to form a single laundry tub or which may be mounted together to form a tub having a plurality of sumps; to weld two lik stampings of sheet metal sumps together to form a tub having two sump compartments; to interconnect a pair of like sump stampings with removable bolts at the top flanges to form. a laundry tub having a pair of of to form additional bracing means; and in general, to provide a sheet metal type of stationary laundry tub which is simple in construction and economical of manufacture.

Other objects and features of novelty of my invention will be either specifically pointed out or will become apparent when referring, for a better understanding of my invention, to the following description taken in conjunction with the accompanying drawings, wherein:

Figure 1 is a plan view of a laundry tub embodying features of my invention;

Fig. 2 is a front view in elevation of the structure illustrated in Fig. 1;

Fig. 3 is an end view in elevation of the structure illustrated in Fig. 2;

Fig. 4 is an enlarged, broken sectional view of the structure illustrated in Fig. 1, taken on the line 44 thereof;

Fig. 5 is a view of structure, similar to that illustrated in Fig. 1, showing a modified form of my invention;

Fig. 6 is a view of the structur illustrated in Fig 5 when secured together by welding;

Fig. '7 is an enlarged broken sectional view of a modified form of bracket for supporting the legs of the tub;

Fig. 8 is a view of structure, similar to that illustrated in Fig. 5, showing a stationary tub having a single sump;

Fig. 9 is a view of structure, similar to that illustrated in Fig. 6, with the two sump portions releasably secured together;

Fig. 10 is an enlarged sectional View of the structure shown in Fig. 9, taken on the line |0--l 0 thereof; and

Fig. 11 is an enlarged sectional view of the structure illustrated in Fig. 9, taken on the line Il-l| thereof.

Referring to Figs. 1 to 4 inclusive, I have illustrated a unit sheet stamping forming the stationary laundry tub l2 having a right and left hand sump l3 and I4 respectively. The sumps have adjacent drain holes l5 into which the bottoms l 6 of the sumps drain. The adjacent; edges of the bottom are interconnected by a plate ll which strengthens the structure while providing a shelf for storage. In view of the interconnection of the sump by plates ll, legs are required only at the outer ends of the sumps I3 and M. Stirrup-like brackets iii are welded or otherwise secured at the forward and rear corners of the sumps, as illustrated in Figs. 2 and 3.

Legs are formed from pipes l9 having threaded ends which are adjusted in the straps l8 and locked in position by the clamp nuts st for the purpose or supporting the laundry tub at the j edge is extended along the sides at 2 3 and across the back at 25 spaced from the rear wall 28 so as to provide a rear ledge 2?.

The sumps are spaced apart to provide the ledge 28 in continuation of the rear ledge 2'27.

The ledge 28 is provided with apertures 29 for the purpose of supporting a wringer board when the wringer is to be attached between the two sumps.

Centrally of the sumps it and id soap dishes 38 are formed in the ledge 27 which drain int the sumps. In the rear ledge 27?, aligned with the ledge 28 a pair of apertures 32 are provided for the conduits to which a faucet is attached.

In'Fig. 4, I have illustrated the ledges 23, 26,

and 25 as being formed by extending the top portion outwardly at 33 then downwardly at 36 and coiled inwardly and upwardly at 35. This provides a finish to the tub and at the same time derstood that a single dip is required to form the.

sumps of opposite hand in the sheet metal stamping and it was for this reason that further showing was made of a sump stamping constructed from a die which may be employed alone or in combination to produce one, two, or a larger number of sumps in a unit laundry tub.

Referring to Figs. 5 to 11 inclusive, I have illustrated stampings 36 and 31, both of which have a sump 38 stamped from the same die. In this arrangement the aperture 39 is located centrally of the sump bottom l6 which drains toward the aperture. It will be noted from the figures that the stampings are otherwise similar to that illustrated in Fig. 1 having the rolled edges 23, 24, and 25 provided thereon which can likewise be produced in similar dies or rolls. It will be noted that the right hand edge of the stamping 3G is trimmed along the central line of the ledge 28.0f the structure illustrated 'in Fig. 1 and that the right hand edge of the stamping 31 is trimmed in the same manner. The two edges are then abutted and welded together as illustrated in Fig. 6. Thewelding .is accomplished preferably by the flash welding method and dressed so that after a finishing operation the junction line between the two stampings will be invisible.

It is also within the purview of my invention to provide all of the .edges of the stamping 36 with the rolled rims 23, 24, and 25 and construct a single sump laundry tub having legs at the facer corners thereof. It is to be understood that the assembled stampings 3B and 87 of Fig. 6 have attached thereto the sump joining plate i7 and also the stirrup-like brackets it and It. The same brackets and legs would be employed on the single sump type or tub illustrated in Fig. 8.

In Fig. 7, I have illustrated a stirrup M which difiers from the stirrup id in that the outer leg 62 extends parallel to the side of the sump and is welded thereto rather than to have both legs of the stirrup welded to the bottom. Otherwise the mounting and the support for the legs is the same as that described hereinabove relative to the stirrups i8.

Referring more particularly to Figs. 9, 10, and 11, I have illustrated a further form which my invention may assume. The stampings 36 and 3? are releasably joined so as to permit the shipment of the laundry tub in knocked-down condition. The projecting edge d3 of the stamping 86 overlaps the offset edge it of the stamping 3?, the edges being secured together by a plurality of bolts 5 having the heads thereof enclosed in a molding 56 which covers the Joint between the two stampings. In a similar manner, a plate 4? extends over the apertures 39 of the sumps and over the drain bushings M by which they are clamped by the nuts 49 which seal the bushings to the base 56 of the sump. A shelf plate Elmay be attached to the inner connecting plate 41 for the purpose of forming a shelf between the two sumps without having the plate 5| welded or 1 otherwise secured to the metal thereof. The stirrups l8 or M are attached to the side edges of the sump as pointed out hereinabove for the purpose of supporting the legs l9.

While I have described and illustrated several embodiments of my invention, it will be apparent to those skilled in the art that various changes, omissions, additions and substitutions may be made therein without departing from the spirit and scope of my invention, as set forth in the accompanying claims.

What I claim is:

l. 'A tub embodying a plurality of like stampings each stamping including a sump having a I central opening in the bottom, a pair of said stampings having their edges Joined, means for releasably securing the edges of said stampings together, a bottom brace having apertures aligned with the apertures in said sumps, and bushings extending through said apertures for securing the brace to the bottom of the sumps when the bushings are secured in position.

2. A laundry unit including, a plurality of sump elements having a drain opening in the bottom thereof, means for releasably connecting said elements together nearthe top, a plate having apertures near the ends which align with said drain openings, and tubular members extending through said drain openings for securing said plate to the bottom of said elements.
