STAIR COVER AND NOSING.

$PECIFICATION formingpart of Letters Patent N 0. 718,821, dated January 1903- Applioation filed August 23, 1902. Serial No. 120,811. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM HARMEN COOPER, acitizen of the United States, residing at New York city, in the county of New York and State of New York, have invented new and useful Improvementsin Stair Covers and Nosing, ofwhich the following is a specification.

This invention relates to a stair cover and nosing designed and constructed in a continuous piece of angular contour to protect one end and the front edge or two ends and the front edge of a step and dispensing with the necessity of joining separate parts of a nosing by a miter at the corner or angle, the intersection of the front edge and end of the nosing being either slightly rounded or square.

A further purpose of the invention is to provide a metal nosing having a bottom which tapers in a curved plane downwardly in front to fit steps which are slightly worn round on the edge and also to generally improve this class of devices to render their application simple and their operation effective.

A still further purpose of the invention is to provide a metal nosing so constructed that the tapering edge thereof continues downwardly as far as necessary to cover the entire front edge of steps and preferably made in one continuous piece without fastenings appearing at the front and having such fastenings inserted from the top and hidden by a suitable covering.

With these and other objects and advan tages in View the invention consists in the construction and arrangement of the several parts, which will be more fully hereinafter described and claimed.

In the drawings, Figure l is a perspective view of a step-nosing embodying integral ends and a front member illustrating the features of the invention. Fig. 2 is a similar view of a step-nosing embodying the features of the invention and illustrating an end and front side member intersecting each other at an angle. Fig. 3 is a section through steps taken in a transverse plane and showing the improved nosing and stair-covering applied thereto. Fig. 4 is a transverse vertical section through a portion of a step-tread, showing the improved nosing applied thereto and having an extended depending front covering member, a step-covering also being shown in connection with this form of the nosing. Fig. 5 is a transverse vertical section of a portion of a step tread, nosing, and covering embodying the features of the invention, the front of the nosing extending downwardly over a portion only of the front edge of the tread. Fig. 6 is a top plan view of a portion of the improved form of nosing embodying a modification.

Similar numerals of reference are employed to indicate corresponding parts in the several views.

This invention embodies features of improvement on the device disclosed by Peter Rasmussen in his Patent No. 507,457, granted July 19, 1898, the said patent having been fully assigned to me.

In the several forms of nosing embodying the features of the invention and shown in the accompanying drawings threeessential features are resident, and consist of a securing-flange 1,with a front upstanding marginal covering member 2, and a depending guard 3. The guard 3, as shown by Fig. 4, depends fully over the edge of the tread of a step or completely covers said edge to protect the same and obviate wear thereon. The guard shown by the remaining figures has less dependence and only partially covers the front or exposed edge of the tread and is adapted to be applied either in the first instance or first construction of the step-tread or after the latter has become worn, and by this disclosure it will be understood that it is intended to construct the guard of difierent lengths for application to step-treads of various thicknesses or to cover such treads at the exposed edges as may be found necessary to shield and protect the same against wear. Either form of the nosing may be conjointly used with a shield or covering applied to the face of the riser, and as the exposed edges of step-treads are usually rounded the inner portion or face of both forms of guard is concave, as at 4, to conform to the contour of the tread edge. The outer face of the guard continues through the medium of a regularlycurved plane into the outer surface of the covering member 2 to avoid the formation of angular projections, which would be highly detrimental in view of the wear upon foot-apparel and the inconvenience that would be encountered by heels catching on the angles, ifsuch existed. The covering member2,rising above the upper surface of the flange 1, provides a front terminal stop for the marginal edge of a covering 5 formed of linoleum, rubber, or other suitable material. Furthermore, it will be observed that the improved nosing is devoid of front fastenings, or, in other words, the guard 3 is imperforate, and the fastening-screws 6 or the like are passed through the flange 1 in a vertical direction and caused to penetrate the tread in rear of the guard.

Another feature of the improved nosing is the integral construction of one or two end members '7 with a front edge member 8, as clearly shown by Figs. 1 and 2, to avoid the corner miters and joints usually found in this class of devices and to obtain the advantage of applying the complete nosing to a steptread at one operation without the inconvenience arising from joining separate end members in relation to a front member. As shown by Figs. 1, 2, and 6, the end members may intersect the front members in either curved or angular planes, in accordance with the formation of the corners of the treads.

Another advantage of the improved nosing is that the edge of the tread does not have to be specially constructed to receive the same, and, furthermore, the greatest thickness of material of which the nosing is composed is located opposite the point where the greatest wear falls upon the tread edge.

It is proposed to construct the improved nosing of metal or metal alloy suitable for the purpose, and brass will be found preferable in View of its durability and capability of being highly polished.

To accommodate different applications, changes in the form, proportions, and minor details may be resorted to without departing from the spirit of the invention.

Having thus described the invention, what is claimed as new is 1. A nosing for the purpose set forth comprising one.or more end members integrally intersecting a front member, the said nosing and its one or more end members each comprising flanges having upstanding covering members and depending guards, the latter being downwardly curved to cover the upper edge portions of a step.

2. A nosing of the class set forth, comprising a flange having an upstanding covering member and a depending guard, the outer face of the guard being curved in a convex plane and the inner face of concave contour, the inner and outer faces of the guard converging to the lower edge of the latter.

3. A nosing of the class set forth, comprising a securing-flange increasing in thickness toward an upstanding marginal covering member and a depending guard, the said guard having an outer convex face and an inner concave face, the two faces converging toward the lower edge of the guard.

In testimony whereof I afiix my signature in presence of two witnesses.

WILLIAM HARMEN COOPER.
