CARPET-FASTEN ER.

SPECIFICATION forming part Of Letters Patent NO. 600,514, dated March 15, I898. Application filed February 17, 1897. erial No. 623,807. (No model.)

To ctZZ whom it may concern.-

Be it known that I, EDWARD A. COLL, a citizen of the United States, residing at Pitts burg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Carpet-Fasteners, of which the following is a full, clear, and exact specification.

My present invention relates to a new and useful improvement in devices for securing carpets to floors without the necessity of driving tacks theretliirough, and has for its object to improve upon the construction shown and described in a certain application for Letters Patent filed by me upon the 16th day of September, 1896, and bearing Serial No. 505,965.

lVith these ends in view this invention con sists in the details of construction and combination of elements hereinafter set forth, and then specifically designated by the claim.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now be described in detail, referring to the accompanying drawings, forming a part of this specification, in which- Figure 1 is a perspective of a nail made in accordance with my improvement and an eyelet secured in the edge of a carpet for engagement with said nail; and Fig. 2 is a section of a portion of a carpet and the eyelets secured therein, showing it in engagement with the head of the nail.

In carrying out my improvement as here shown I provide a nail A, the body thereof being suitably sharpened, so as to be readily driven within the iloor, and this nail has secured thereon or formed therewith the head B, which is of such shape as to readily enter into engagement with an eyelet C. By slotting the head, as indicated at D, a certain amount of resiliencyis given to the two halves thereof, so that when the eyelet is forced thereover these sections will spring toward each other and exert sufficient tension upon the sides of the eyelet to prevent its accidental withdrawal from the head, and as a further protection against withdrawal of the eyelet from the head the eyelet may be reduced in internal diameter at the lower por tion thereof, as indicated at E, so that when it is forced over the head the sections of the latter will first spring toward each other and after passing the reduced portion of the eyelet will react outward, as shown in Fig. 2, thus securing the eyelet with sufficient force to prevent its accidental disengagement.

In practice the slot D may be extended downward into the body of the nail and be utilized as a tool-seat and gage for driving the nail to the proper depth-as, for instance, when the nail is driven so as to bring the bottom of the slot level with the floor this will be an indication of the proper depth.

In applying the eyelet to the carpet, before the lower portion E thereof is turned outward to form the flange F, it is forced through an opening previously made in the carpet by a sharp-pointed tool, which crowds the thread thereof sidewise, but does not cut the same, after which the flange F is formed in any convenient manner, preferably so that the upper flange G, as well as the flange F, will be embedded within the fabric sufficiently to avoid coming in contact with the floor or the shoe of a person Walking thereon. This arrangement permits the carpet to lie flat upon the floor and avoids any rocking movement at the points where the eyelets are secured and also any rocking movement of furniture placed thereon at these points.

One of the principal advantages of my improvement is that the cost of manufacture is exceedingly small, while at the same time the fastener is rendered very durable, since no delicate spring parts are formed in the eyelet, and itis, therefore, not easily disarranged.

Having thus fully described my invention, what I claim as new and useful is-- In combination an eylet formed of a single piece of sheet metal bent into cylindrical form, flanges around the top and bottom of the cylinder for securing the eyelet in the carpet, a shoulder formed in the cylinder by abruptly reducing the diameter thereof, and a nail, a spherical head on the nail, said nail having a vertical slot run through the head into the body of the nail, said slot dividing the head into two resilient halves to engage the shoulder of the eyelet, said slot being adapted also for the reception of a tool the ends of which project on each side of the nail and determine the depth to which said nail can be driven, substantially as described.

In testimony whereof I have hereunto affixed my signature in the presence of two subscribing witnesses.

EDWARD A. COLL.
