STAlR-CARPET FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 720,447, dated February 10, 1903. Application filed August Z, 1902. Serial No. 118,057. (No model.)

To a/ZZ whom t may concern:

Be it known that I, CURTIS-W. LESLIE, a

citizen of the United States, residing at Pittsburg, county of Allegheny, and State of Pennsylvania, have invented certain new and useful Improvements in Stair-Carpet Fasteners, of which the following is a specification. g Myinvention relates to stair-carpet fasteners.

The object of the present invention is the provision of a stair-carpet fastener of simple, ornamental, and inexpensive construction which can be quickly and easily applied to the carpet and stairs to secure the stair-carpet and which will be compact and lie flush against the carpet covering the riser.

A further object is to provide a stair-car.- pet fastener having an improved and novel catch for locking the parts thereof and permitting rapid and easy release when it is desired to detach the fastener for any purpose.

Having the foregoing objects in view, the invention comprises certain improved features and novel combinations of parts, appearing more fully hereinafter, and recited in the appended claims.

In the accompanying drawings, Figure 1 is a view illustrating the application of the fastener to a stair-carpet and showing the position of the parts when the fastener is first applied; Fig. 2, a similar View showing the fastener after it has been secured; Fig. 3, a detail perspective viewl showing the hinged or pivoted member in positionjus't prior to engagement with the spring-catch;. Fig. 4, a view showing it engaged with the catch; Fig. 5, a longitudinal section of the fastener when the hinged member is engaged with the catch, and Fig. 6 a cross-section.

The device consists, essentially, of two parts, a bodyl and a member 2, hinged or pivoted thereto.

The body 1 is preferably made ornamental and provided with the lateral extensions 3 to give a good bearing on the portion of the carpet covering the riser of the stairs. The body is elongated and provided with the points or prongs 4 at its lower end, while its upper-portion has the two slits 5 and 6, providing a spring locking-catch 7, having notches 8 and 9 at its opposite edges, and a perforation 10,-

through which a nail can be introduced to ldisengage the spring member from the catch when it is desired to release the carpet-fastener from the carpet.

The hinged member 2 has the iianges 1l and the curved point or prong 12, and it is hinged or pivoted by a pin 13, passing through the body and the ends of the flanges. The hinged member is thus pivoted, so that when it is closed into engagement with the springcatch its flanges lie in the body. On the free ends of the flanges are cam' projections .14, back of which are notches 15, said cam projections and notches being so disposed that the cam projections are adapted to snap past the free end of the spring locking member to permit the projections to snap into the notches 8 and 9.

In applying the fastener the prongs on the body are first pressed down into the carpet on the tread of the stairs about three-eighths of an inch from the riser and the point or prong on the hinged member inserted into the carpet lying against the riser. The body is then pushed forward, and the spring locking member snaps into engagement with the hinged member and locks the fastener, with the ornamental lateral wings lying against the carpet on the riser. It will of course be understood that the points or prongs pass through the carpet and into the stairs. To disengage the fastener, a nail can be inserted through the opening in the spring looking member and the parts pried apart.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is-

l. Astair-carpetfastenercomprisingabody having a point or prong and a spring locking member, and a pronged member pivoted to the body and adapted to engage with the spring locking member on the body.

2. Astair-carpet fastener comprising abody having a prong and a spring locking vmember having notches on its opposite edges, and a pronged member pivoted or hinged to the body and provided with projections adapted to snap into engagement with the notches on the spring locking member.

3. A stair-carpet fastener comprising a body having a prong and a spring locking member ICO provided with notches in its opposite edges, and a pronged member pivoted to the body and provided With flanges adapted to telescope into the body and having projections adapted to snap into engagement With the notches on the spring looking member.

4E. Astair-carpet fastener comprising a hollow body, a point thereon, lateral Wings, and a spring locking member provided with notches on its opposite edges, all of said parts being in a single piece, and a pronged member having flanges and pivoted to the body and adapted to telescope therein and provided With notches and cam projections, said projections being adapted to snap into engagement with the notches on the locking member, and the notches on the hinged member to receive portions of the locking member.

5.l A stair-carpet fastener comprising a pivoted elongated hollow body having slits at one end and an integral spring locking member defining the slits, and a pronged member hinged to the body and adapted to telescope therein, which is adapted to engage with the spring locking member.

In testimony whereof I hereunto affix my signature in presence of two Witnesses.
