Application filed May 8, 1914. Serial No. 837,153.

To all whom it may concern Be it known that I, BENJAMIN F. FREE MAN, a citizen of the United States, residing at Long Island City, in the county of Queens and State of New York, have invented new and useful Improvements in PacketFasteners, of which the following is a specification.

My invention relates to packet fasteners and ties, and has for its object the provision of such a device which will secure, without knotting, the end of the cord that had been passed around the packet; which will reliably'remain in the securing position; which in this position will moreover maintain the cord tightly around the packet so that neither the individual papers or parts of the packet nor the fastener itself can slip; and which may be readily released by a simple movement so as to disengage the end quick and easy unfastening of the packet.

While the invention is capable of wide use and applicatiomit is especially designed for and applicable to the use of mail clerks who must fasten packets rapidly and easily in such an effective manner that they will not become loose or unwrapped, and so that: they may be quickly and readily unfastened when desired.

The invention consists in the novel construction, arrangement and combination of parts shown in the accompanying drawings and hereinafter described, it being understood that the embodiment of the invention disclosed is to be considered as illustrative and that modifications may be devised Without departing from the spirit and scope of the invention.

In the drawings-Figure 1 is a plan view of the fastener, the attached cord being broken off at a short distance therefrom; Fig. 2 is an inverted side elevation of the same; Fig. 3 is a side view of a packet with the securing'cord in position and held by the fastener; and Fig. 4 is a plan view of the same.

Referring to the drawings, it will be seen that the fastener consists in a body formed of wire spirally wound, the successive convolutions at increasing in diameter from the center. A represents this body, which may be made of any preferred size of wire, and of any preferred size according to the size and weight of the packet to be fastened.

The outer end a of the spiral, and also the inner end, may be finished off in any preferred manner, preferably in such a way as not to catch or chafe the cord or the packet with which. the fastener is used.

The fastener A is shown as, and is preferably given, a conical form, the apex a of the cone corresponding to the central portion of the spiral. The wire employedis preferably of spring metal, so that when proper pressure is applied the cone is capable of being compressed, and when the pressure is relieved it is capable of assuming its conical shape.

The cord or other flexible connection B with which the packet is to be bound or fastened is being passed through a central aperture at the apex of the cone and having a knot b at the end which is of such size that it will not pass through the aperture.

In the fastening of a packet by the use of my fastener, as shown in Figs. 3 and 4:, the packet is held in one hand with the body A held under the thumb with the apex at against the packet. The cord is then passed around the packet one or more times in at least two directions, preferably, say longitudinally and then crosswise, to form binding bands which hold the packet together. The cord is next passed around itself under the body A of the fastener and immediately adjacent the same, one or more times, to form a locking loop. The body A is then inverted and turned under the bands, thus partially at least compressing the convolutions of the spiral so that a spring pressure is exerted between the body of the packet and the binding bands, with the locking loop caught and securely held in between. In this position the fastener will remain securely held so that the end of the cord cannot become loose, and the spring action will maintain the binding bands tight around the packet.

In order to release the fastener, or untie the packet, the end of the cord is given a quick outward and upward pull, which results in withdrawing the fastener body A from its inverted position under the binding bands and the cord may then be unwound from the packet at once.- It will therefore be seen that no manual manipulation of the fastener body is required in unfastening, and there are no knots to be untied.

preferably secured to the body A by 1 Having described my invention, What I claim as new and desire to secure by Letters Patent of the United States, is

1. A packet fastener comprising an axially resilient button and a cord centrally attached thereto.

2. A packet fastener comprising a spring Wire axially resilient button and a cord centrally attached thereto.

3. A packet fastener comprising a spiral spring Wire body incombination With a cord secured to the central portion thereof, substantially as described.

4; A packet fastener comprising a conical spring Wire body in combination With a cord extending outwardly from the apex thereof, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.

BENJAMIN F. FREEMAN.
