Patented May 2, 1950 NirEo STATES. ea'rsm OFFICE 7 Claims. l This invention relates to a sink rimparticular1y one that is to be used between the nanges of` aA sink mounted in a shelf` or similar support coveredV with linoleum or like material, and forms an improved means for joining the sink with` the.

linoleum.

It has for an object toA provide an improved means for joining the sink` with the linoeumV and making a waterproof connection between them.

It is also an object torprovide an improved construction of rim for this` purpose, which not onhl. forms a water-tight joint at the sides of the sink but may also be extended up over the back-splash and form a waterproof joint therewith, and will also have an improved front edge construction at the forward edge of the sink and shelf..

It is a further object to provide an improved construction of this type of device which will per,- mit the use of ledge type faucets for supplying water to the sink, and these faucets may be mounted on this metal rim structure to produce a much improved appearance and prevent possibility of moisture seeping through the openings around the faucets or the pipes leading to them.

A further object is to provide an improved construction of this type of device which will provide means for clamping down the linoleum or similar covering adjacent to the sink in such` a manner that it will not pull away or creep back from the rim or the sink, and also one that will maintain indeiinitely a watertight joint between this covering and the rim of the sink.

Another object is to provide an improved means for mounting the rim structure, and, one tha-t may be mounted in such a way as to permit removal of the sink if desired, with a minimum of difculty, and without having to remove or disturb thev linoleum or other surface iinishing material adjacent the sink.

With the foregoing and other objects in View, I have devised the construction illustratedV in the accompanying drawing forming a part of this specication. It is, however,` to be understood the invention is not limited to the specific details of construction and arrangement shownbut may embody Various changes and modifications within the scope of the ivention.

In this drawing:

Fig. l is a perspective View of the device installed with a sink in a shelf or other similar arrangement;

Fig. 2 :Is an enlarged section of a side edge structure taken substantially on line. 2 2 of Fig. 1;

Fig. 3 is a detail section through the backsplash. facing structure, taken substantially on line 3-3 of Fig. 1;

Fig. 4 is a detail section of the front edge struc,- ture taken substantially on lne4-4 of Fig.,1;

Fig. 5 is a detail section through the uprightedges of the splash portion taken substantially on line 5 5 of. Fig. 1; and

Fig; 6 is a section similar to a portion of Fig.,2;

showing a slight modiiication,

The device comprises a metal rim structure preferably of relatively soft metal, including side portions It` joining the rim flange Il of a porcelain or enamel covered sink4 I2 with the adjacent linoleum or otheriinishing covering I3, the whole assembly being supported by a plywood or similarly constructed shelf or other suitable structure I4 provided with an opening I5 in which the sinkis mounted, the iiangeor rim` |I of the sink resting on this shelf or supporting structure around the periphery of the opening I5, asshown in the drawing. The rim structure also includes a rear horizontal' portion I 5 at the back of the sink, and this is extended upwardly at its rear edge to form an upright splash` portion I'I. At the forwardedge of the sink it includes aforward horizontal portion I8 terminating in a downwardly extending ange I9 at the front of the` shelf and sink. The whole rim comprising these diff ferent portions is preferably formed' in one integral pieceA or structure as this eliminates joints and facilitates mounting7 as well as giving a better and more attractive appearance,but it will be understood it may be made in different sections if desired.

Each ofthe side portions IU of the` rim, as shown more clearly in Fig. 2, is so constructed that it is provided with, a downwardly directed knife edge rib or. protrusion 2li` at or near the outer edge of this portion I Il, which` joins` the linoleum or other covering I3. The adjacent edge of the covering I3, which may be of linoleum, Formica martite, wall board or the like, is` bevelled and rabbeted in such away that.

ithas a thinner edge portion ZI with its top surface 'i2` below the top surface 23 of the main bodyH of the covering I3 to receive the knife edge. o1?

rib 20,. Thus,` as will be` seen from Fig. 2., Vilhen the portion I!! is forced or pulled downwardly against the linoleum or other covering, this, edge or rib. 20 will bite or be, forced` into the material forming the covering I3 at the point ofthe joining of the thicker portion of the covering and the. thinner portion 2 I. The clamping means. iepleierably a bolt, any number of which foundM desir.- able may be. used, indicated, at 2.4. secured at its.

upper end to the under side of the portion I 6. In the structure shown, this upper end is threaded at 25 into the metal of the rim structure I0 and may be soldered to prevent its loosening. Also, a nut or heavy washer 26 may be welded to the under side of the portion ID, as indicated at 21, and tapped to receive the bolt, thus insuring a stronger and more reliable connection between the bolt and the rim. Or, if preferred, this reinforcement for securing the bolt could be cast as a lug or boss on the under side of the rim. It

will be understood that by tightening the nut 28 i on the lower end of this bolt the rim may be..

clamped firmly against the linoleum or otherV covering and the sharp rib or portion 2U will be forced into or bite into this material, providing a Y.

very tight connection between the covering and the metal rim and one that will prevent the cov--` ering from receding or drawing away from the metal rim. .It-isalsopreferredto bevel orin` 29 isfoverlapped by.Y the rimV andthe surface 30 will bev tightly clamped over the surface 29. The

inner edge .3I is also similarly inclined, as well as theY opposed surface 32. of the metal rimto `pro..

V cline the opposed faces 29 and 3|).so .that the base.

It is also preferred that the *covering I 3 be laidr on a layer of felt or similar material 34 placed between this covering andthe supporting ture I4.

InorderV to maintain a constant grip on the covering i3 by the rim, even after the unit has been assembled in place for some time, it is preferred to provide a large split spring or lock strucwasher on the bolt -between the nut and the` supporting structure I4. As this washer is a large one it provides an increased contact surface with the supporting structure, and as it is a split spring or lock washer it keeps tension on the bolt and rim at all times, so that even after being in place for some period of time the rim is still securely forced against the covering I3 tomaintain the tight joint between them. In addition, the lock washer prevents the nut from loosening.

To insure that the other or inner edge of the metal rim will t snugly against the flange I I of the sink, this-edge is shaped into a downwardly directed Vknife edge or sharp flange 36, and when thegrim or. frame Il) is made ofV relatively soft is irregularthisrim -36 may be -tappedlightly with aV hammerto make it conform tothe sur-v A face of theilange I I and insure a tight .connection betweenthem. Y l .A

InV order to insure that awater-tight Vor water-Y proof seal is made, when the unit is assembled a sealing compound or cement 31, such,V for examp1eas damp proof paste mastic, is applied between. the metal rim and the other surfaces against o1' opposed to it. Also to increase the cohesiveaction between the rim and the sealing compound, linearer longitudinal grooves 38 may.

be cut in the under surface of the rim, thereby making the under surface ,of the rim irregular and also increasing this surface area by which the mastic paste is held in place. It also permits the use of a greater amount of sealing material to prevent water seepage. Y Y.

In this Vnew construction of rim or frame, the horizontal surface I6 at the back of the sink is a continuation of the side surfaces I6, and this rests on the rear portion of the flange Il, as shown in Fig. 3, the same as the side portions I6, it being provided with the same inner knife edge or sharp flange 36 to engage the surface of the sink flange, and also having the grooves 38 for the sealing material 31, and it is clamped in the same way by the bolts 24. The rear edge of this` portion I6, however, is extended upwardly as shown at 39, over the face of the back wall 46, and. the back splash 4i of linoleum or other suitablematerial is inserted in back of this extension, asl shown in Figs. 3 and 5. For this purpose thel upright edges 42 and the top edge 43 are rabbeted`l kor recessed, as indicated at 44 and 45, to receivel the edges of this covering, and the edges 42 and?i 43 are "rounded'and directed rearwardly, termi-I nating in knife edges 46 and 41, which are pressed? into and bite into the surface of the linoleum or" other covering whenthe device is clamped againstthe back wall by the securing means, such as the" screws48. These sharp edges securely grip thelf'f covering and hold it in place and prevent it fromj; drawingaway from the metal rim structure.v It

also insures a water-tight joint between the metal' y terminates in a downwardly bdirected knife edge or sharp flange 36th`is being a continuation of the knife edge or flange 36 of the side portions, and it is clamped against the forward portion of flange II of the sink by the securing bolts 24, as shown in Fig. 4, the same as are the side portions IU, and the joint is also lled with the sealing material 31 and the under side is provided with the same grooves 38. At its outer edge,'however, this front portion is raised somec what above the surface I8, as shown at 50, forming a rim across the front of the frame or rim structure, and this provides a stop wall .5I to prevent liquids on the rim running over the front edge. The outer portion of the rim is extended downwardly, as shown at I9, over the outer edge of the shelf or supporting structure I4, to protect it and provide a neater and more attractive appearance, and the space between this rim structure and the shelf or supporting structure, bothrat the top and at the outer edge of the shelf, may be filled with the sealing or mastic, material 31g, as indicated at 52.

As will be seen from Fig. 2, the joint between the-rimV I6, and the covering I3 is such that the topY surfaces of these two elementsV are substantially flush or on the same levelfbut a slightly different joint between the rim and this adjoining-material is shown in Fig. 6, the other or inner' edge clamping portion on the rim II V.of thesink being the same as that shown in Fig.Y 2. As shown in this Fig. 6 the metal rim 53 corresponding to thegrim I0 is partially bevelled at its ,edge 54 to meet the similarly inclined or bevelled edge 55 of the linoleum or other covering 56, similar to the inclined or bevelled .edges 3| 32 of .the structure of Fig. 2. A flange or lip 51 isA formed on .the outer edge and isturned down into a knife edge 58, but protrudes fromV 'accuses form, when the rim 53 is forced downwardly by the securing means, such as the bolt 24, this sharp edge. 58` will bite into the top surface of the covering 56, forming a tight joint. This may also be sealed by sealing compound or cement 59, the same as shown at 22 in the rst form.

With this' construction also, the ledge type of faucetsl for supplying water to the sink may' be employed, as shown in Fig. 1. In this view, the single combined adjustable outlet spout for both faucets is shown at GU, with the usual control' handles 6| for the control valves, the discharge outlet and the handles being located above the rear wall i6. `This gives a very much improved appearance and permits sealing of the openingsi for these elements in the rim structure to prevent seepage of water through to the wooden supporting structure, or the linoleum or other covering.

It will be seen from the above that the whole rim structure surrounding the sink can be made in one unitary structure, including the upright back or splash wall Il, and that it provides a sealed watertight joint with the linoleurn or other covering entirely` around the sides and back of this rim structure, preventing the entrance of moisture under the rim structure at any point, and thus maintaining dry, sanitary conditions in the assembly at all times. Also, the linoleum or other covering for the shelves or other supporting structure, including the back or splash wall, are tightly gripped and held by this rim structure, so that there is no chance of its drawing away from it to open up the joint between them to permit entrance of water or other liquids.

If used with stainless steel or all metal sinks, this rim could be welded or soldered to the sink ange Il at edge 36 if desired. This would insure a watertight joint and eliminate use of paste in the joint between the rim and the sink. This would also make the rim and the sink in one piece so that they could be installed in one piece in one operation.

Having thus set forth the nature of my invention,
