' KNOTLESS PACKAGEFTIE Italo Raymond Trevisan, Newark, NJ.

Application December 11, 1943, Serial o. 513,930

The present invention relates in general to package or bundle ties and more particularly to a package handle adapted to tighten and secure the package binding in a knotless tie.

The use of handles secured to package bindings for the purpose of carrying is well known. One of the familiar handles of this type is hooked onto the binding after the latter is tightened and securely tied by a knot.

In unwrapping a package thus bound, it is first cal necessary to untie, break or cut the binding. I

This step in the procedure of unwrapping is often tedious and frequently results in injuries such as chafing of the fingers in attempting to break the binding, or cutting due to slippage of a knife usedin severing it.

It is an object of the present invention to avoid these inconveniences and possible injuries by providing a package handle with means for tightening and securing the binding without-tieing a knot therein.

Another object of the invention is to provide a handle of the character described with means for hooking the binding whereby the package may be supported and carried.

A further object of the invention is to provide such a handle with means for mai'ntainingthe tie securely until it is desired to remove the handle and binding from the package.

The operation of removing the handle and binding from a package thus secured is simple requiring merely the removal of the handle which simultaneously releases the binding.

Numerous other objects and advantages of the Fig. 4 is a plan view of a package and binding to which the handle is about to be applied.

Referring to the drawing. the numeral H1 designates generally a package handle embodying one form of the present invention.

In Fig. 1, handle I0 is shown in carrying position on a package ll secured with a binding I! such as cord, twine, string, tape, or the like.

The handle shown comprises two parts, a wire portion l5 and'a wooden or fibrous hand grip l6 threaded onto the wire to protect the hand in carrying. The grip l6 may,of course, be dispensed with in some instances, or may form an integral part of the handle in other embodiments of the invention.

The wire l5 may be'a continuous length bent downwardly at IT, I8 adjacent the ends of grip l6, thence upwardly and downwardly in outwardly extending reverse or S-shaped bends I9,

20 to form support or carrying hooks 2], '22. From these extremities, the wire is bent inwardly in

lengths

23, 24 substantially in parallel alignment with the-grip and united in a downwardly formed intertwining spiral grippin post 25.

The spiral shown in the drawing is left-hand,

but a right-hand spiral is sometimes desirable.

I use the term spiral in its broadest sense.

throughout'this specification and claims. Furthermore, it is to be understood that roughening or corrugating the post 25 for 'the purpose of gripping the binding is contemplated by the invention. And the mere 'use of a material for the post which provides a sufficiently high coefficient of friction between it and the binding would likewise be within the meaning of the term gripping as used herein, even though the post may be made smooth on its binding-engaging surface.

The two ends of the wire I5 which extend beyond the spiral 25 are shaped to form a pair of oppositely disposed tightening and

tying hooks

26, 21 which take the form of an elongated S as shown in Figs. 1 and 3, with the leading points or

ends

28, 29 preferably on a slightly lower plane than that of the central portion of the 8 formation.

Fig. 4 illustrates the first step in tightening and tying a binding l2 on a package utilizing the above described handle ID. The binding is first wrapped around the packageleaving the ends of the binding free. The binding need not be tight before the hooks are inserted under'it as shown in Fig. 4 because, after the hooks are thus positioned, turning the handle in the direction indicated by arrows in Fig. 4 and about a vertical axis through the spiral 25 will result in twisting the binding around the spiral which both tightenes and ties the binding effectively. The support hooks 2|, 22 are then hooked onto the binding thereby locking the binding in its tightened and tied condition on the spiral and also providing means for carrying the package.

When the load of the package strains at the binding, the strands of the binding surrounding the post or spiral 25 are forced into more intimate contact with each other and with the spiral thereby increasing the frictional engagement between the overlapped portions, of binding on binding and/or binding on post and increas'mg the security of the tie.

To release the handle from the package binding, the hooks 2|, 22 are first withdrawn from engagement with the binding and the handle is then turned counterclockwise, as viewed in Fig. 4, to unwind the binding from the post 25. This single unwinding operation loosens and unties the binding which may then be readily removed from the package.

It-is thought that the invention and many of its attendant advantages will be understood from the foregoing description and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form herelnbefore described being merely a preferred embodiment thereof.

I claim:

In a knotless tying device, a gripping post, hooks radially disposed adjacent an end of said post and adapted to gather portions of a binding to be tied, including the loose ends of said binding, and to initiate the wrapping of said gathered binding around said post when the device is rotated, thereby forming a knotless tie in said binding, locking hooks spaced from said post for engaging portions of the binding, and a handle whereby said device may be gripped and the package supported, said locking hooks serving both to support the package by its binding and also to maintain the security of said knotless tie.
