Patented Jan. 4, 1949 UNITED STATES PATENT OFFICE 3 Claims.

This invention relates to a securing device.

An object of the invention is to provide an improved securing device by which a flexible element may readily be secured about one or more articles and readily released therefrom.

Another object of the invention is to provide an improved securing device which will firmly hold a fiexible filament by means of a simple hitch rather than a knot.

Another object is to provide an improved securing device which may be easily and economically manufactured.

Another object is to provide an improved securing device which will be small and easily stored and handled.

Another object is to provide an improved securing device which will be composed of few, simple, and cheaply produced parts.

Another object is to provide an improved securing device which will be neat and attractive in appearance.

Another object is to provide an improved securing device in which the tension of the flexible filament may easily be adjusted.

Other objects will hereinafter appear.

The invention will be bettter understood from the description of several practical embodiments thereof, illustrated in the accompanying drawing, in which:

Figure 1 is a perspective view of one form of securing device embodying the invention, being applied to a generally rectangular package, showing the manner in which the binding filament is tightened;

Figure 2 is a similar view showing the filament just as it is moved into locking engagement;

Figure 3 is a perspective view, to an enlarged scale, of the filament engaging element of Figures 1 and 2;

Figure 4 is a view similar to Figure 3 of a modified form of filament engaging element;

Figure 5 is a perspective view of another form of filament engaging element showing its application to an envelope, parts being in positions they assume when the engaging element is released;

Figure 6 is a fragmentary view, to an enlarged scale, of the filament and filament engaging element of Figure 5 with closely associated parts of the envelope; and

Figure 7 is a fragmentary perspective view of another form of filament engaging element secured to an envelope.

Referring first to the form shown in Figures 1, 2 and 3, the fastening device consists of a flexible element of filament, such as a piece of string or cord I, having one end secured, as by a single knot 2 formed at one end, to the end of a securing element in the nature of a tag, frog, or toggle indicated generally at 3, the cord of filament passing through a hole in the tag so that the knot is pulled against one side thereof.

The tag is fiat and generally elongated in shape, and in one side has formed a deep notch or slot '4 penetrating approximately half its width and inclined to form a kind of hook for receiving the filament l, the notch preferably being somewhat wider than the filament and having relatively smooth edges, so that the filament can run through it easily.

Centrally of the end of the toggle which is remote from the hole through which the filament passes is a tapered notch 5. The notch 5, the inner end of the slot 4, and the hole are all substantially in alignment, centrally of the tag.

In Figure 1 the securing device is shown as partially applied to a generally rectangular package or stack of articles 6. It will be noted that the filament extends partway across the top of the package, down the far side, under the bottom, up the nearer side, and over the top of both the package and the toggle to the slot 4, than through this slot and along the underside of the toggle, its end being gripped between the thumb and fingers of the hand I of the user.

After looping the filament around the package as described, the cord may be tightened by a pull of the hand, keeping the parts in the positions indicated in Figure 1, the filament sliding through the slot 4, so that the tag acts somewhat in the manner of a fair-lead or dead-eye during this part of the operation.

When the operator has pulled the filament until he is satisfied with the tension upon it, he moves his hand to the left to bring the gripped end of the filament substantially under the center line of the tag and then pulls the end upwardly as indicated in Figure 2.

This brings the filament up through the notch 5, and the tension upon the filament causes it to wedge itself within this notch. The operator can now release his hold on the filament and it will be ti htly retained, both by the friction between the filament and the sides of the notch 5 and also because of the position of the two abrupt bends in the filament and by friction where it passes under the tag between notches 4 and 5.

The tag is conveniently made of any relatively stifi material, such as sheet metal, heavy cardboard, fibre, or plastic material and conveniently may be punched from sheet stock. If molded, the end of the cord may be encased to secure it to the tag. The cord can be secured in any desired manner, as by stapling, adhesive, etc., but the hole and knot seeems to be the simplest manner of attachment.

The inner end of notch is most conveniently formed as a space with parallel sides, substantially narrower than the filament, so that the latter will be very tightly gripped if it is brought to this narrow space.

In Figure 4, a modified form of the tag is shown as of generally triangular shape, having two slots I'M in its sides, corresponding to notch 4 above described, and a single notch I05 in the side opposite the apex to which the filament H3! is attached.

Of course the notches I04 do not extend quite to the center line, but are sufiiciently deep that the tag is not swung very greatly from one side to the other by tension of the cord.

In Figures 5 and 6, a tag is shown as directly connected to a flap 207 of an envelope 2%. The filament 2m passes through an aperture in the back of the envelope and has its knotted end 202 projecting through a washer or patch 262a to afiord it a firm anchorage.

The tag itself has a somewhat arrow-like head 203 which is passed through parallel slots 208 in the envelope fiap, and the projecting end has a slot 204 corresponding to slot l, above described, and a V-shaped notch 205 corresponding to notch 5.

It will be noted that when the envelope is in closed position, the inner end of slot 204 is substantially in alignment with the perforation of the envelope 296 through which the filament 2!)! extends.

To secure the flap to the body of the envlope, the cord is brought upwardly through slot 206 and then downwardly into wedging engagement with notch 205.

This alone firmly secures the flap to the envelope in an easily detachable manner, but should a more permanent fastening be required, the cord may be wound around the head 2% and the opposite end of the toggle one or more times, as indicated in Figure 6, being wedged between these tag ends and the envelope and flap, and each turn more firmly securing the parts in closed relationship.

In Figure 7, the tag is shown as permanently secured to the envelope flap by adhesive or the like, for this purpose having a flared end 303 held by the adhesive by the underside of the flap. The cord 30! is secured in any desired manner and, the notches 3M and 305 correspond precisely to the notches 2M and 205 of the preceding figure. This form of tag may be made integral with the envelope flap, particularly if the latter 4 be reinforced by an extra ply of material glued to it.

While I have described the illustrated embodiments of my invention in some particularity, obviously many other embodiments, variations, and modifications will readily occur to those skilled in this art, and I do not, therefore, limit myself to the precise details shown and described herein, but claim as my invention all embodiments, modifications and variations coming Within the scope of the appended claims.

I claim:

1. A tying device for use with a flexible filament comprising a fiat tag having a perforation through which a filament may be passed, the tag being formed to define a notch extending inwardly from one side of the tag at an intermediate point and a notch having tapered sides at the edge of the tag remote from said perforation, the inner end of the first mentioned notch being substantially in alignment with and between the perforation and the second mentioned notch.

2. A tying device for use with a flexible filament comprising a fiat tag having a perforation throu h which a filament may be passed, the tag being formed to define a notch extending inwardly from one side of the tag at an intermediate p'oint and a notch having tapered sides at the edge of the tag remote from said perforation, the inner end of the first mentioned notch being substantially in alignment with and between the perforation and the second mentioned notch, the first mentioned notch being inclined to a line passing through the hole and a second mentioned notch at an acute angle on the side toward the perforation.

3. A tying device for use with a flexible filament comprising a fiat elongated generally rectangular tag'having a hole for securing a filament thereto adjacent one end, the tag being formed to define two notches disposed at an obtuse angle to each other, one of said notches being wider throughout than the thickness of the filament and extending inwardly intermediate one side of the tag and the other of said notches at the end of the tag remote from the hole tapering from a width substantially greater than the thickness of the filament to a width substantially less than the thickness of the filament.
