fi Claims (ciao--74) This invention relates to improvements in cove base molding, the molding being suitable to form a curved connection between the covering of the floor and walls of a building. The objectof the shaped cove base molding that is readily installed at the juncture of the wall and floor and against the edges of which are abutted the corresponding edges of the wall and floor covering sheets so that a smooth continuous unbroken surface of covering for the floor and walls is presented. Another object is to provide a floor and wall covering including a cove base molding connecting the covering for the floor and walls, at the junctures thereof, that is economically furnished and installed. Other objects and advantages of the invention appear in the following description.

An illustrative embodiment of the invention is shown in the accompanying drawing, in which:-

Fig. 1 is a perspective view of the floor and wall of a building to which the invention is applied, the View being fragmentary;

Fig. 2 is a perspective view of a section of a cove base molding embodying the invention; and

Fig. 3 is a transverse section of the molding shown in the other views.

The illustrative embodiment of the invention consists of a strip I of covering, preferably made of a composition of material in sheet form with an asphalt base, such as is commonly used for surfacing the floors and walls of buildings. The middle portion of the strip I, from one end to the other, is bent so that the

opposite side portions

2 and 3 of the strip extend in planes substantially at right angles to each other. The bent portion 6 preferably is arcuate and is shaped to present more or less curvature as may be desired between the flat

angular portions

2 and 3 of the strip.

Upon the outer face of the angular strip thus formed is permanently secured a reenforce consisting of a stiff metallic plate 5 shaped to fit snugly and cover the back faces of the cover strip I, and has numerous barbs 6--! that project into the body of the strip. Preferably, the marginal edges B9 of the: plate extend beyond the corresponding edges l0ll of the strip for the purposes hereinafter described. The barbs may be formed in any suitable manner, such as by punching small portions of the plate through the back thereof so that undetached projections forming the barbs extend from the opposite face thereof.

In forming the cove base molding, the strip l is heated to such degree of temperature that it becomes more or less plastic, and is then laid upon the barbed faceof the plate 5 after which force is applied by any suitable equipment (not shown) to cause theplate and strip to become impressed togetl'ier so .the, barbs become imbedded in the 5 body of the strip." During this operation, owing to, thetendencyi of the plastic body, material to crowd intothe barb openings 12 in the plate, the barbs are forced backwardly and become clinched to somev extent in the body of material of which the strip is formed.

The operation of bending the middle portion of the stripand plate may be accomplished concurrently as they are pressed together, or, they may be bent separately preliminary to the pressing operation for uniting them finally together. These operations are accomplished by the use of suitable mechanical equipment (not shown) such as may readily be devised with the exercise of mechanical skill known in the art.

In use, the base strip thus formed is positioned in place with the back of the plate resting against the floor l3 and wall I4 of a building and is there held in place by applying a suitable adhesive material between the plate and the corresponding faces of the floor and wall. Sheets Iii-l6 of covering, preferably made of material, similar to that of which the strip l is formed, are then placed upon the floor and against the wall It with their corresponding edges l1-l8 abutting against the edges |ll2 of the strip l and overlapping the corresponding marginal edges 9-8 of the plate 5. The sheets l5 and I6 are secured in place by means of a suitable adhesive such as in common use. After the molding and sheets have been properly assembled and secured in place the continuity of the exposed faces of the sheets and strip is substantially uniform. Also,v even alinement of the sheets with the strip at their junctures is established and preserved because of overlapping of the sheets with respect to the marginal edges of the plate irrespective of unevenness in the surfaces of the floor and wall that ordinarily occur.

I claim:

1. 'A pre-shaped cove base molding constituted of an asphaltic cover strip, the middle portion of said strip from one end to the other being bent and the opposite side portions thereof extending in planes substantially at right angles to each other, said bent portion being arcuate, and a bent metallic reenforce consisting of a stiff metallic plate secured to the back of said cover strip conforming to the adjacent faces thereof and provided with numerous integral barbs that are imbedded and clinched into the body material of said strip, the marginal edges of said plate extending beyond the corresponding sides of said strip.

2. A pre-shaped cove base molding constituted of an asphaltic cover strip, the middle portion of said strip from one end to the other being bent and the opposite side portions thereof extending in planes substantially at right angles to each other, said bent portion being arcuate, and a bent metallic reenforce consisting of a stiff metallic plate secured to the back of said cover strip conforming to the adjacent faces thereof and provided with numerous integral barbs that are imbedded and clinched into the body material of said strip.

3. A pre-shaped cove base molding constituted of an asphaltic cover strip, the middle portion of said strip from one end to the other being bent and the opposite side portions thereof extending in planes substantially at right angles to each other, said bent portion being arcuate, and a bent metallic reenforce consisting of a stiff metallic plate associated with said strip, extending along and conforming with the arcuate portion of the strip upon the back thereof, said plate having numerous integral barbs that are imbedded and clinched into the body material of said strip.

4. A pre-shaped cove base molding constituted of an asphaltic cover strip and a stifi metallic plate associated with said strip secured to the back thereof and provided with barbs that are imbedded in the body material of said strip, said strip and plate being bent from one end to the other to form an arcuate middle portion and fiat adjacent portions that extend substantially at right angles to each other.

5. A pre-shaped cove base molding constituted of an asphaltic cover strip and a stiff metallic plate associated with said strip intimately secured to the back thereof, said strip and plate being bent from one end to the other to form an arcuate middle portion and adjacent portions that extend substantially at right angles to each other.

6. A pre-shaped cove base molding constituted of an asphaltic cover strip, and a reenforce consisting of an arcuate stifi" metal plate associated with said strip intimately and permanently secured to the back faces of said strip before said molding is installed to provide a connection between the covering sheets for the floor and walls of a building.
