CARPET-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 620,782, dated March 7, 1899.

Application filed November 19, 1898. Serial No. 696,852. No model.)

To (all whmn it may concern.-

Be it known that I, LEOPOLD KERN, a subject of the Czar of Russia, residing at Hillsborough Bridge, in the county of Hillshorough and State of New Hampshire, have invented certain new and useful lm provements in Carpet-Fasteners, of which the following is a specification.

This invention relates to an improved carpet fastener, by which the carpet can be readily applied to the floorand removed therefrom for cleaning without the use of tacks; and the invention consists of a carpet-fastener comprising a permanent socket-section provided with a shank, a solid head portion above said shank, a hollow perforated head portion at the side of said solid head portion, and a cap-section provided with a threaded shank adapted to engage the head of said socket-section at its perforation, and, further, in certain details of construction and arrangement of the parts to be more fully described hereinafter and finally claimed.

In the accompanying drawings, Figure 1 represents a floor, showing a number of permanently-applied socket-sections of my improved carpet-fastener arranged at suitable locations thereon. Fig. 2 is a plan View of a floor with a carpet laid thereon and held in position by myimproved fasteners. Fig. 3 is a vertical transvere section on line 3 3, Fig. 2, drawn on a larger scale and showing the method of attaching the carpet to the floor by means of my improved fastener. Figs. 4 and 5 are respectively a top view and a vertical central section on line 5 5, Fig. 4; and Figs. 6 and 7 are a top view and a vertical central section on line 7 7, Fig. 6, of the detachable portion of my improved fastener.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents the lower or socket section of my improved carpet-fastener, and B the detachable cap portion of the same. The lower section A is provided at one side of its center with a nail or screw shank a and with a solid head a above said shank. The remaining portion of the head of the socket-section is made hollow and provided with an opening a The solid portion a of the rounded-off head of the socket section a is smaller than the hollow portion.

' The solid portion a is provided with a transverse nick a by which the shank can be screwed into the floor if a screw-shank is used, as in Fig. 5. Then an ordinary nailsha-nk is used, as in Fig. 3, the socket-section A is driven into the floor by a hammer in the usual manner. The rounded-off socket-section A, with its solid and hollow head portions and its shank, is preferably made of cast metal and is secured to the floor nearthe wallin such a manner that the hollow portion in the head is located toward the wall, as shown in Fig. 3.

The detachable cap portion B is formed of a convexo-concavo cap of sheet metal, to which is attached a central coarsely-threaded shank b, as shown in Fig. 7. Before the carpet is laid the socket-section A is driven into the floor near the wall. The edge of the carpet is placed over the head of the socket-section A and the threaded shank of the cap portion pressed or screwed through the carpet, so as to enter through the opening a into the lower hollow portion of the head of the section A, as shown in Fig. 3, in which position the shank b engages the edge of the opening a and the shank of the socket-section A, retaining the carpet firmly in position thereon due to the strain exerted by the carpet in the shank of the cap-section and the head of the socket-section. The location of the head of the socket-section on the floor can be readily ascertained by placing the carpet over the same and feeling with the finger for the head, after which the shank of the cap portion is forced through the carpet either directly or by giving the cap-section a few turns until the above connection with the head of the socket-section A is obtained. WVhen the capsection is placed in position, the strain of the carpet establishes the connection between its shank and the head of the socket-section A,

so that the cap-section cannot be released therefrom, the edges of the opening in the adjacent solid portion biting on the coarse threads of the shank and retaining the same against the tension of the carpet. When it is desired to take up the carpet, the cap-section is removed by turning it on its axis. As soon as the cap portion is released from the stationary section it can be withdrawn from the carpet and the latter be taken up.

By my improved carpet-fastener carpets can be laid down or taken up in a quick and convenient manner without special tools and without the use of tacks. The fastener can be furnished at a very low price.

The carpet-fastener can bemade in different sizes and of different metals, the cap-section being preferably made ornamental,as the same is visible,while the socket-section,which is covered, does notrequire any extra finish.

I am aware that a carpet-fastener consisting of two sections, one of which is permanently attached to the floor and the other con nected by suitable fastening means to the socket-section, is old. I do not claim such a fastener; but I am not aware that the special construction shown by me by which the sections can be applied without special tools has ever been used before my invention thereof.

Having thus described my invention, 1 claim as new and desire to secure byLetters Patent 1. A carpet-fastener, consisting of a permanent socket-section provided with a shank, a solid head portion above said shank, and a hollow perforated head portion at the side of said solid head portion, and a cap-section provided with a central threaded shank adapted to engage the head of said socket-section at its perforation, substantially as set forth.

2. A carpet-fastener, consisting of a lower or socket section, composed of a shank at one side of the center, asolid head portion above said shank, and a hollow and perforated head portion at the side of said solid head portion, and a cap-section provided with a central threaded shank adapted to pierce the carpet and engage the hollow portion of the socketsection, substantially as set forth.

3. In a carpet-fastener, a lower or socket section composed of a head solid at one part and provided with a shank below said solid portion, and a hollow portion of larger size than the solid portion and provided with a perforation, substantially as set forth.

4. In a carpet-fastener, a lower or socket section provided with a shank on one side of the center line, a solid portion above said shank, and a hollow portion of larger size than the solid portion and at one side of the same, and provided with a perforation in its apex, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in pres ence of two subscribing witnesses. I

LEOPOLD KERN.
