-MU'UNTING FOR COWINED WALL BA$E AND FLOOR CDVIERINGS Application filed December 22, 192?. Serial No. 2ll,836.

The invention relates to a mounting for linoleum or the like providing integrally associated walhbase and floor engaging portions, and to a fillet for application at the juncture of the fioor and wall as a backing for the linoleum thereat. t

An object of the invention is to provide a mounting of the class described in which the linoleum portions adjacent the juncture of n the door and wall are so shaped as to tend to maintain their form thereat.

Another object of the invention is to provide a fillet for use at the floor and wall angle which provides an efiective backing for the la opposed linoleum portion and is engaged by the same to a maximum amount.

A further object of the invention is to provide a mounting of the character described whereby linoleum or other suitable covering an materials may be readily applied to existing structures.

The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the followtt ing description of the preferred form of the invention which is illustrated. in the drawings accompanying and forming part of the specification. lt is to be understood, however, that variations in the showing made by an the said drawings and description may be ado j ithin the scope of the inventionas 4. in the claims.

iteiciring to said drawings:

Fig re 1 is a fragmentary vertical sectional view through a wall and floor at the juncture thereof and showing a floor covering mounted thereat in the manner of the invention.

Figure 2 is an enlarged and somewhat diagrammatic iew of a portion of the showing to of Figure l.

Figure :l is a view similar to Figure 2 showing a modified for of the invention.

As herewith particularly illustrated, the method and means of my invention is applied to the laying of a sheet of linoleum 4 on a floor 5 of a room with integral edge portions of the linoleum sheet extending upwardly along the base-board 6 of a plastered wall 7 of the room, whereby sharp crevices are avoided at the floor edge and liquid may not escape from the floor at the base-board. In order to avoid a breaking of the floor covering at the juncture of the floor and baseboard, a portion 8 of the linoleum between the floor engaging portion 9 and the base board engaging portion 11 thereof, is shaped to extend obliquely across between the floor and wall-base to avoid the corner thereat. Since the linoleum portion 8 is spaced from the wall and baseboard, a backing member in the form of a fillet molding 12 is referably disposed in said corner for bac ing and supporting the portion 8.

Heret'ofore it has been a general custom to provide a fillet in such corners in the form of a preformed mold either of triangular cross-section or of cove section.

When a triangular mold is used, it has been i found that the distinct angle which. must be made in the linoleum at the junctures of the oblique mold face with the floor and wall tend to crack the linoleum thereat. and that difficulty is experienced in eflecting and maintaining a proper engagement of the linoleum against said moldface. On the other hand, cove molds heretofore used for the purpose have been formed with their concave faces cylindrical and tangent to the floor and wall at their junctures therewith whereby but one distinct bend is made in the linoleum, and that one is cylindrical. Yet the use of such a fillet has not been found any better than a the use of a triangular fillet, for the shaping and disposal of the linoleum to conform to and forcibly engage the cylindrical face of the molding has been found very difficult in practice. In accordance with our invention, however, the fillet molding 12 is so shaped that the linoleum may be fitted thereagainst with particular certainty as to the provision and maintenance of a proper and permanent backing therefor, and the installation is one which may be readily made in houses at any time, either primarily or as a replacement.

Referrin now more particularly to the showing 0 Figure 2, it will be noted that the fillet molding 12 is rovided with a flat face 13 engageable w1th the floor 5, a

flat e 1 g g ebl g t the outer face 16 of the base mdld 6, and a concave face 17 against which the linoleum ortion 8 1s marily in order to avoi 1 tion 23 of the surface of the concave moldthe face 17 at such I surface 21 of the abuttigg padding, such surarranged to be disposed. Pre erably, and as shown, a vertical edge 18 is defined at the juncture of the

molding faces

13 and 17, such ed e being equal in height to the depth of a ayer of felt or pager padding 19 arranged .to be interposed etween the linoleum and floor, whereby the surface of edge registers with the face constituting the e ctive floor surface for the purpose oflayin the linoleum. Pria sharp edge thereat, the molding portion the molding faces 14 and 16 may also be cut away to provide a flat edge portion 22 thereat.

It will now be clear that the linoleum is to be fitted against the base-mold surface 16 b and the upper surface 21 of the padding, with the linoleum portion 8 tangentially related to said surfaces, and the face 17 of the fillet molding is so formed as to permit such a disposition of the linoleum. A pormg face 17 is cylindrically curved about an axis A intersecting the bisector B of the angledefined by the base-mold and

floor surfaces

16 and 21 respectively, with the radius of curvature thereof appreciably exceeding the distance of said axis from either of said surfaces whereby the arc of curvature O of the surface 23 intersects the planes thereof at an acute angle. Preferably and as shown, the surface portion 23 extends only over an arc ofabout degrees, with the line B bisecting the arc. The remaining portions 24 and 26 of the surface of the molding face 17 extend tangentially from the edges of the surface 23 to the

edges

22 and 18 of the molding increasing radius tangency with the in curves of constantly whereby they approach planes of the

surfaces

16 and 21. Owin to the length of the radius ofcurvature o the surface 23 exceeding the distance from the center to the wall and floor surfaces, the radii of curvature of the parts of the surface portions 24 and 26 immediately ad acent. the surface 23 provide distinct and rounded short bends in the mounting surface defined by the

various surfaces

23, 24 and 26. In the resent embodiment, the bend 27 of the sur ace 26 lies inwardly of the edge 18 of the fillet molding 12, while the bend 28 of the surface 24 lies substantially at the edge 22 of said molding-in other words, theportions 24 and 26, and particularly the latter, extend appreciably beyond the edges of the portions 23.

In mounting the linoleumportion 8 against the backing surface shaped as described, the

, portion 8 is forced against the mold with the at the juncture of when the installation is made.

fillet molding surface whereby

complementary bends

29 and 31 respectively are formed in the linoleum. Owing to the resiliency of the linoleum, the

'bends

29 and 31 tend to straighten out and so urge the adjacent linoleum portions to assume and maintain a pressure engagement with the backin surface. In this manner, the linoleum portlon 32 between the

bends

29 and 31 is resiliently held against the surface portion 23 of the fillet molding when the

bends

29 and 31 of the linoleum are seated in the bends 27 and 28 of the backing surface.

Means are provided for securing the linoleum in forcible engagement with the fillet mold, and as here shown such means comprises a cap mold 33 arranged to be engaged over the top edge 34 of the base-board engaging portion 11 after the linoleum portion 8 has een pressed into position against the fillet molding,and pressed downwardly as far as I ossible, after which it is fixed in place as by nails 36. In this manner, the linoleum is forcibly held in place at all times and the tendency of the linoleum portion 8 to straighten out, particularly at the

bends

29 and 31 thereof, is arranged to act positively to urge the linoleum portions at either side of these bends to maintaintheir engagement with the backing surfaces. The use of an adhesive substance, particularly at the

bends

29 and 31, would of course provide a supplementary means for holding the. linoleum in place against'the fillet. If desired, the generally triangular space above the fillet edge 22 and behind the linoleum may be filled with a filler 36 which would be applied in plastic form when the installation is made.

In the embodiment disclosed in Figure 3, a fillet member 41 is provided having the plane faces thereof of equal width and having its concave face 42 cylindrically curved about the same axis for its entire width, with its radius of curvature also exceeding the distance from said axis to the bearing surfaces of the base-board and floor as in the other embodiment. The upper bend 43 of the linoleum would in this instance occur, as before, opposite the top edge 44 of the fillet molding, while the lower bend 46 of the linoleum would occur substantially opposite the lower and vertical edge 47 of the fillet at the juncture of the bottom and concave faces thereof. In the latter case, it is noted that the linoleum would be spaced from the fillet and padding ad acent the bend 44, and the space provided would preferably be filled with a plastic filler In the present instance, the axis of curvature A of the face 42 is equally spaced from the planes of the vertical and horizontal fillet faces, whereby, if the linoleum be laid with the padding omitted, its disposal with respect to the edge 47 of the fillet would be the same as at the edge 44 thereof.

We claim: y

1. In combination with a wall intersecting a floor, a covering having integrally associated floor and wall engaging portions, and

a preformed fillet cooperatin with said wall and floor to define a concave acking surface for said covering, an intermediate portion of said surface being cylindrically curved about an axis disposed at a distance from said wall and floor which is less than the radius of ourvature of said portion, and the portions of said surface adjacent said first portions being curved for tangency both to said first portion and to the surfaces of said wall and floor, the spirally curved portions of said surface forming abrupt bends with the cylindrically curved surface for the purpose described.

2. In combination with a wall intersecting a floor, a covering having integrally associated floor and wall engaging portions, and a fillet disposed at the juncture of said wall and door and cooperating therewith to define a concave backing surface for said covering thereat, the backing face of said fillet being so shaped that when said covering is disposed thereagainst, an intermediate portion of the covering opposite said backing surface will be cylindrically curved about an axis disposed at a distance from said wall and floor which is less than the length of the radius of curvature of said intermediate portion of the covering and a covering portion on each side of said first portion will each have a shorter radius of curvature than has said first portion to provide short bends which tend to straighten out and urge the adjacent portions of the covering to maintain a pressure engagement with the backing surface.

In testimony whereof, we have hereunto set our hands at Napa, California, this 11th day of December, 1927.
