Patented Feb. 2, 1932 UNITE WILLIAM F. TAYLOR, OF LAFAYETTE, INDIANA SINK Application filed July 1, 1929. Serial No. 374,988.

This invention is a novel improvement in sheet metal sinks and ts ob ects are to provide a sink which can be economically constructed with no rivets or fastening means showing on the interior of the sink, and in which the members of the sink are united outside the sinkand form flanges by reenforcingribs which imparts great rigidity to the sink, and having heavy fillets in the cor- F ners formed from the metal from which the body of the sink is made; all parts being so shaped that there will be noangles or corners in the sink in which dirt might accumulate; so that such sink can be easily cleaned.

1 will explain theinvention with reference to the accompanying drawings which illustrate several constructions of sink embodying the essential novel features ofthe invention. In the claims I have summarized theinvention and the subordinate features thereof for which protection is desired.

In sai'ddrawings; I I

Fig. Sis an enlarged detail view showing how the corner fillets may be formed integral with the sink members.

. As shown in Fig. 1 the back 1 and bottom 2 of the sink may be formed of one piece of sheet metal; the connecting portion or joint.

between the members 1 and 2 being curved as shown at 1f. The back 1 has a rearwardly projecting flange 1a at top, andrearwardly projecting flanges 1b, 10 at each side. 5 The bottom 2 has depending flange 2a atits front edge and dependingiflanges 2?) at its sides.

The front 3 and opposite sides 4 of the sink, as shown in Fig. 1 are formed of one piece of metal. The front 3 has a flange 3a on its loweredge which fits against the front flange 2a of the bottom; and each side memher 4 has a flange 42) on its lower edge adapted to fit against the adjacent side flange 2b of the bottom 2. Each side 4 also has an; end'flange'4c adapted to flt against-the'ad jacent side flange 1c of the back 1. W hen the parts are assembled as shown in Fig. 2 the meeting flanges 1 c40; '2b4b;

2a3a, are rigidly united by'rivets, or other suitable means, and are inseparable when united; and the flanges when .thus unit-ed form a series of strengthening ribs on the exterior of the sink, see Fig. 2, which ribs impart great stiffness to the sink, and thoroughly reinforce it. y f

The corners of the sink are preferably formed bypressing the metal of the members into a parti-spherical shape as indicated at 3g, 4g. This may be done by removing surplus metal between the lines my as indicated in Fig. 8, and pressingthe remaining parts in spherical contour and welding theline 1 between the adjacent sections of. theumetal.

so that there will be no angles at the corners.

Any slight crevices or grooves that might. be left at the bottoms of the curved portions 36, 46 or at theupper edges of the junctions of the flanges 3a, 2a; 4b, 2b; 40, 10; can be filled with solder so that there will be no place within the sink where dirt can catch and accumulate. Y v

The lower edge of the front 3 is inwardly curved as at 3e,and.the lower. edges of the sides 4 are inwardly curved asat 46; also the adjacent ends of the sides 3-a-nd 4 are-com nected'by rounded portions or bends 3f and the rear endsof the sides 4 adjacent flanges 4c are inwardly curved as at 4;; and all the corners are concaved or rounded as at 3g-4g, so that there are no sharp angles on the inside of the sink and no place for dirt to catch or accumulate.

Preferably the backl is widened above the sides 4, as shown, the part of the back projecting above the sides 4 being slightly wider than the part of the back intermediate such sides. Y Y I The flanges lc are on the ends of the narrower portion of the back, and the flanges 1b,

on the edges of the wider portion of the back.

In order to strengthen the back and prevent its bending between the adjacent ends of said flanges 1b, I provide angle-iron reinforces 5 intermediate and connecting the adjacent ends of said flanges. Each reenforce 5 is preferably formed of sheet metal having offset upper and lower portions 5a and 5?) connected by intermediate angle portions 50. The portions 561,55 of the reinforcements are respectively fitted to the adjacent ends of the flanges 1b, 10, behind the back, and riveted, or otherwise rigidly secured, thereto. Pref "erably the parts 5a, 55, 5Q of the reinforcing inember are provided Withstiffening flanges on their side edges as shown more clearly in The back is provided with suitable openings 1 and 1 for connection of faucets, etc. By having the drain opening 1 adjacent the back of the sink the chain (not shown) to which is attached the plug stopper (not shown) will always hang close to the back wall and be lessliable to be caught by movement of articles being washed in the sink.

Preferably the bottom 2 is slightly depressedtoward its rear end and center to di rect' water to the outlet opening. 1 which may be connected with'the drain pipe (not shown) in'the usual manner, so that water will readily drain out of the sink.

The flange la is alsopreferably provided This depression can be used for retaining soap, scrub brushes, etc. which are customarily placed on the ledge formed by the top of the back wall.. This depression can drain to 1 the front of the splash-back.

Ifdesired'the upper edges of the front and side members of thesink can be finished in any otherl suitable way preferably with integral head or flange such as shown at 3t inFi gs. l we or such'a head could be formed separately and secured thereto. Preferably I proyide'the upper edges of the side and front nembers with integral beads, suchas 3t, to enhance the appearance of the sink stiffen the upper edges of the front and sides; thereof. i

In the sink shown in Figs. 3 and 4, the back and bottom members are constructed as above described, butthe front and side members are formed separately. As shown the front is provided with a flange 32' at each end; and each side 4% islprovided with a flange 4 5 at itsffront end adapted to register with the ad jacent flange 32' when the parts are, assembled and the meeting flanges 32', 41' are riveted or otherwise rigidly secured together. With the exceptions above noted the parts of the sinkxshowh in Figs. 3 and 4t are constructed as in Figs. 1 and-2, and similar parts are similarly lettered in the figures. The construction shown in Figs. 3 and 4 enables the front and sides to j be made out of smaller sheets of metal than the construction shown in Figs. 1

, and Q theflanges 32', 42 form additioneas es flange 2.9 which is riveted to the flange 18 when the parts are assembled. The flanges 21), t?) (Figs. 1 and 2) are dispensed with, but the flanges 3i, 4?? and 10, are retained. With these exceptions the bottom, back and sides in Figs. 5an d 6 are formed as above described; similar parts being similarly lettered in the igures.

In my improved sink the various members are rigidly united by flanges riveted or otherwise secured together, but the fastenings be tween the sections areall outside of'the. sink,

thus enhancing the sanitary value thereof; and such exterior flanges stiffen the sink and prevent deflection thereof when-loaded.

The reinforces 5 overcome any tendency of the back to bend at thejunctionof the sides therewith and enhance the rigidity and durability of the structure.

T he sinks are shownas mounted on tubular legs 6 having adjustable feet 6a; but any other suitable supports can be used. The adjustablefeet allowing'the sink to be readily levelled regardless of inequalities in the floor level.

The improved sinks are very sanitary owing to the absence of angles or corners where dirt might collect; all rivetsare ontheexterior of the sink; all'seam's are-,sweated with solder until extremely smooth; the location of the drain makes for greater convenience in operation. The exterior flanges form ribs uniting the sink membersand re-enforce the sink body and render it rigid and strong and the re-enforcements prevent the back bending above the sides.

Each member of the sink has a curved junction of the sides with each adjacent member which curvature makes the sink easy to clean. The portion of the back projectingv above the sides forms a protector or splashback, and the flangeson the top and sides of the back form with the back and inclosure for the plumbing fixtures. All rivets being on the exterior of the sink the possibility of collection of dirt at rivet edges is eliminated and by this construction there is no danger of shearing any rivets.
