SPECIFICATION forming part of Letters Patent No. 398,492, dated February 26, 1889.
Application tiled November 2l, 1888. Serial No. 291,454. (No model.) l
To all whom t may concern.:
Be it known that I, JOSEPH E. CALDWELL,
a citizen of the YUnited States, residing at Good- E land, in the county of Sherman and State of 3 Kansas, have invented a new and useful Improvement in Carpet-Fasteners, ot which the following` is a specification.
hook in one direction and enables the hook to be firmly secured in this position.
Frein the above description the operation of the 'fastener will be obvious. After having secured the strips to the ldoor thefree ends ofthe revoluble hooks are turned outward, the edge of the carpet is extendedover The object of this invention is to provide a f simple, cheap, and easily-operated carpet-fastener,`and this object is attained in the device that is fully described hereinafter in eonneci tion with the accompanying drawings, and spei cically pointed out in the appended claim.
In the drawings, Figure I is a view ot the improved fastener shown in its operative position. Fig. 2 is a detail perspective view of the fastener. Fig. 3 illustrates an angular strip. Fig. 4 is a detail view of one of the hooks.
Referring by letter to the drawings, A A designate metallic strips or bars provided at suitable intervals with plain openings a a, through which are passed screws B B to securethe strips or bars to the floor close to the wall. The strips or bars are also provided at short intervals throughout their lengths with the tapped apertures C C, in which are fitted the lower threaded ends of the revoluble metallic hooks D D. These hooks are curved forward gradually toward their upper ends, and they are adapted to be turned outward, as shown at d d in Fig. I, or turned inward, so that their extremities fit close to the Wall of the room, as shown at CZ d', Fig. l. The hooks are provided close to the upper surface of the strip or bar with a shoulder, E, which when the free end of the hook is turned inward bears firmly on the surface of the strip or bar and prevents further rotation of the the hooks and the hooks are passed therethrough, after which the free ends of the hooks are turned inward until the shoulders bind on the strips or bars and prevent further rotation. The t'ree ends of the hooks are now arranged close to the wall, and the carpet is thereby prevented from slipping from the hooks.
The strips or bars may be made of any suitable material, and are made in suitable lengths to enable them to be arranged properly around the room. They may also be made angular, as shown in Fig'. 3, to tit around orina corner.
Having thus described my invention, I clai1n- The herein-described carpet-fastener, comprising the strip or bar A, adapted to be secured to the floor close to the wall and provided at intervals with tapped apertures O C, andthe revol uble hooks having threaded lower ends engaging the said apertures and provided with shoulders Eto bind on the upper side of the strip or bar when the free ends of the hooks extend toward the wall, substantially as specied.
In testimony that I claim the foregoing as my own' I have hereto affixed my signature in presence of two witnesses.
