uiro rarer CHARLES EDWARD LOEHR, OF WOOSTER', OHIO, ASSIGNOR TO THE SAFETY STAIR TREAD OOMPANY, or woos'rnn,

STAIR-TBEAD NOSING.

This invention relates to nosing members for stair treads'and consists of a nosing construction of improved form designed to have important advantages over nosing members as heretofore made and is, moreover, of

simple form adapted to facilitate installation.

The improved nosing member of the pres ent invention is of the type particularly adapted for the protection of the forward edge .of stair coverings, such as linoleum, composition, cork tile, rubber tile, and of similar materials when used on stairs, landings, etc. where the edge would be subjected to destructive wear. It is, moreover, of the simple and well known form comprising, as

' an integrality, a substantially vertical fac-v ing flange, preferably ofcurvilinear cross section having a horizontal securing flange 2 projecting rearwardly therefrom to bear upon the tread surface and provide means for securing the nosing thereto. As hereto fore made, the horizontal securing flanges of this desirable type of nosing have been of $5 uniform thickness and, in consequence, it has been necessary to build up to covering rearward of the nosing or to cut away or rabbet the forward marginal edge surface of the stair tread or to similarly rabbet the undersurface of the floor covering so as to avoid .the excessive wear incidental to the shoulder or highedge at the rear end of the securing flange and to eliminate the danger incident to the shoulder thus formed. In-

pensively installed by merely placing same upon the surface of the stair tread member without cutting and the covering may be laid. thereon withoutdanger of excessive wear.

The described and other features and advantages of the present improvements will OHIO, A CORPORATION OF OHIO.

be more fully understood by reference to the accompanying drawings wherein Fig. 1 is a perspective view illustrating the improvednosing of the present invention as installed.

' Fig. 2 is a vertical cross-sectional the nosing member.

In the approved embodiment of my invention, as here'shown, the nosing'element or member is formed with a curved-nosing or facing flange 1, having integrally. formed view of therewith the horizontally extending securing flange 2-, the latter being provided with suitable apertures for the reception of securing'screws 3 for securing the nosing to. the forward edge portions. of stair treads 4 as indicated. The nosing element may de sirably be rolled or cast of suitable material such as yellow or white brass, adapted to ef- '70 fectively protect the stair covering indicated at 5 and of the character heretofore referred to. The upper portion of the nosing flange 1 extends or projects upwardly above the securing flange 2 a distance substantially corresponding to the depth or thickness of the covering 5' to be applied to the stair tread and the lower portion of the nosing flange 1 may desirably and as shown, project downwardly from the securing flange a distance corresponding tothe thickness of the stair tread 4, thereby to-prese'nt a unitary and attractive appearance. i

The securing flange 2 is integrally formed to extend longitudinally of the nosing and in accordance with the present invention is of improved cross-sectional contour to. facilin tate and effect a substantial economy in install'ation. 'In accordance therewith, the securing flange at its forward edge, where joined to the nosing flange, is.of maximum thickness and tapers therefrom rearwardly whereby the upper surface thereof will substantially converge with the upper surface of:

the stair tread. As shown, e underarmface of-the securing flange is positioned to be in a horizontal. plane to have a firm hearing rest upon the upper marginal edge surface of the stair tread and the tapered form is produced b the progressive and rearward inclination o the upper surface to substantially .a'point or sharpened edge at the rearward extremity of the securing flange. As a result thereof, the stair covering of linoleum, compositiomor other material may be laid of normal thicknes overlying the securing flange 2 and extending forwardly to the nosing. -The structure, accordingly, al-' lows of installing the nosing, without cutting a.

of the tread or cutting or building up of the covering material to be used therewith and the rearward taper of the securing flange substantially eliminates the formation of a shoulder at its rearward edge. The elnnination of the shoulder, as heretofore-described,

overcomes the excessive wear which would occur were the shoulder present and like"- Wise, danger'of tripping and the improved tapered securing flange further provides a desirable slight inclination to the tread surface" at its forward edge conducive to safety upper surface inclined rearwardly to a rearward edge otminimum thickness whereby said upper surface will substantially con-- verge with the surface of the stair tread.

2. -A' nosing member for stair treads and the like comprising a substantiallyvertically positioned nosing flange 0t convex-curvature having a longitudinally extending and integral securing flange extending rearwardly therefrom, said securing flange having its underside surface in a horizontal plane and its upper surface inclined rearwardly to a rearward edge of minimum thickness and said securing flange being spaced from the upper edge of the nosing flange a distance corresponding to the thickness of the covering to be employed therewith, said securing flange being of such. reduced thickness as to allow installation without beveling of the stair tread or of the covering employed therewith.

Signed at \Vooster, in the county of lVayne. and State of Ohio, this 5th day of August A. D., 1925.
