My invention relates. to securing; means especially of: a kind. capable. of. repeated: reuse-,1, partticularly for the quick. closure. and. release: of;

flexible sackspsuch as hop: sacks OrJbags.

In' the.=- handling; of hops. particularly; the: harvesting. thereof it: is: customary to carry the;

more important is. the: fact that the sacks area reusedrand'. being: relatively expensive. must be: The. closure:

reused. a large number: of. times. orsack. tie. correspondingly. must becapable. of

repeated: reuse without any substantial.deteriora tionLas asecuresclosure. It isalsoof importance:

that. theisack tie. be readily adapted to sacks at present in use an'dibe efiective withoutsubstan-- tially changing: the.- normal routine of the user;

It is likewise of. importance that. thesack tie be readily manufactured; be relatively: inex pensive, and be easily installed and. easily re-- moved lif necessary;

It is therefore. anobjecti oh my invention to provide an improved sack tie.

Another." object of. my invention is to; provide a sack 'tie economically and readily manufactured and utilized. in? connection with. present sacks and related 1 equipment;

A furthenobjecti of the. invention is; to provide a sack. tie susceptible to repeated reuse: without substantial. deterioration.

A further object of the-invention is"to'prov-ide"= a sacktie whichcans readily be manipulated by operatorstwithout radically new techniques.

A further object of the invention is to provide:

a sack-tie: which is quitesecure when closed but is readily opened.

Other objects together with the foregoing are attained inthe embodiment of'the invention; de-

scribed in the accompanying description andillustrated in the accompanying drawings, in which Figure l is a side elevation of a sack tie constructed in accordance with my inventionand in positionon a hop sack illustrated in its closed condition.

Figure 2 is-a cross-section; theplane of which is indicated by theline-Z- Z of Figure 1.

Figure 3 is a cross-section, the plane of which is indicated by the-line-3-3 of Figure 1.

Figure 4 is an isometric view of the clip portion of my sack tie.

In its preferred form'the sack tie of my in vention comprises a clip usually" fabricated ofa single sheet of metal-contoured and folded upon itseli to-providea pair of walls defining arecess to receive a part of the sack and to secure the clip to the sack. One of the walls of the sheet. is out-turned to provide 2; lug formed with an 2f. apertures therein. to receive one end of a cord having;- aknot: to. preclude. passage; of the cord, through the aperture. The otherrwall oi theclip isformedinto. a pair. of wingsidefining. a. generally. conical channela of a size to receive the cord wheniitzis. passed around part of. the sack but toprevent thepassage of. another knot. in. the cord which awedges into i the conical channel. In order to afiordreadyeengagement of; the cord with thechannel.- and ready. withdrawal. of ther cord-= and knot: therefrom, the channel is pro-- vided; with an opening between. the wingswhich.

is inclined in: direction. to, thedirection oft the flexible-material'. having anopeniend l. disposed between one side, margin. 8r= and. another: side margin. 9.. The. sack end. I. is, adapted: to be openedto passla char-ge ofhopspintothe-body ll. of the :sack and; then: tmbe gathered" together to; serve as a closureto. preclude.- discharge of the contained hops: V

In. accordance: with my: invention I: dispose. along the. margin. 8., the] seamed margin for: example. a: clip generally designated, l2 This preferably; is an-cart-icle of manufacture fabricated from a single sheetioi material. such as. metal, conveniently stainless. steel. The. clip. is con,- tourecl and. formed. to. provide a. fold. made. up of a. pair .of sidewalls I33 and I4 between. them; establishing. or definingal-recess lfi-of'a suitable size and shape toreceiva the margin 8. oil the each. A. bend l1 atthe end'ioil the recess'betweeni the. walls. I31 and; l4lisislight1y resilient. so that. a tight frictional engagement; oi the. clip. with. the material of the. saclii margin can. be, af; fordedl While. this. alone... might, in some in.- stances, be, a sufilcient.interengagement of the clip and. the sack I; provide. additional securing means. Preferably the material" of the clip. itself; is. deformedlinto indentations. l 8 which can be forced partly into. the material ofthe. sack or. can displace the material of" the sack" for firm intermeshing. Additionally the clip isprovided with perforations l'9"so that rivets'2l' pass.- ing. through the? perforationsand' the sack clamp or rivet the. clip in positi'onso that a relatively permanent attachment is provided;

One of the walls defining. the recess I61 for example: the wall 13; is. deformed to provide an outstanding lug!l having'avflaredterminal 23 and, is pierced" to. aiford. an aperture 23. Ad'apted'to" pass through: the aperture 24is a'fiexiblecord 26 tiedinto a knot" Z'ladjacentone endi While. the? awacse cord 26 passes freely through the aperture 24, the

knot 21 is of sufficient extent to abut the lug and.

preclude passage of the cord entirely'through the aperture so that a firm anchor is afforded.

The remaining one of the'walls, for example the wall [4, is shaped with an inclined off-set 28 affording a generally planar backing and is also contoured to provide a pair of wings 29 and 3! in turn defining a channel 32. The channel 32 is approximately of a conical contour and is open at both ends 33 to receive the .cord. 26after the cord has been passed about the body or neck of the sack 6. The convergence of the Wings 29 and 3| is sufl'iciently abrupt so that they are able to retain an abutting knot 34 also formed in the cord 26 effectively lodged within the converging conical channel 32. a

In order that the cord and knot can readily be engaged with the clip, even though the sack 6 is full of hops, the wings 29 and 3| do not touch or meet and do not form a completely conical channel. Rather they are spaced apart to define an opening 36 between them of substantially the same width as the cord 26 but inclined somewhat to the general direction of the cord as it passes around the sack. The cord must be slightly twisted or deflected in order that it may engage in the channel by passing through the opening 36.

' knots engaging said lug and said wings respec- The contour and edge and shape of the Wings 7 and particularly of their margins are such that they are blunt and rounded and do not afford any sharp edges which might wear or cut the cord 26. Rather, they facilitate its entry into and removal from the channel 32. Also to assist in the interengagement of the cord and the chan- :2."

nel, the cord is preferably of an extra length to provide a grip portion 31 terminating in a knot 38 to afford a good finger or hand-hold.

In the usual use of the sack tie, the cord 26 is not in engagement with the Wings 29 and 3! until the sack has been substantially filled. At that time, the-operator ,oruser grasps the body of the clip and passes the cord 26around the neck of the sack gathering it together into a tight closure. By overpulling on the grip portion 31 of the cord, he is able to provide enough tension so that the knot 34 lies slightly behind and outside of the wings 29 and 3|. Then by giving the body of the cord 23 a slight turn or twist, he is able to pass the cord adjacent the knot through the channel 36. He then slackens his cord grip and permits the cord to straighten as the knot enters into the conical channel 32. The knot continues to do this after the operator releases the grip portion 31 because of the tendency of the sack and its contents to expand near the throat or opening. This expansion is not enough to make any sizable opening and does not permit any contained hops to discharge, but simply maintains a sufficient tension upon the cord so that the knot is wedged tightly into the conical channel between the wings. This is sufiicient to hold the sack closed during all ordinary usage and prevents the contents from spilling or being discharged inadvertently.

When the contents are to be discharged, the operator again grasps the clip and by taking hold of the grip portion 31 and putting extra tension on the cord 26, he is able to Withdraw the knot from the channel 32. By then putting a slight twist on the cord 26, he is able to withdraw it through the opening 36. This removes the knot from engagement with'the clip, and when the user then releases the grip portion 31, the cord 26 falls free, except for its attachment to the lug tively.

2. A sack tie comprising a clip including a single sheet of metal having a pair of walls defining a recess, means for securing said'clip to a part of a sack disposed in said recess, 2. lug outstanding from one of said walls, means for securing a cord having a knot therein to said lug, and a pair of wings outstanding from the other of said walls, said wings defining a channel therebetween adapted to receive said cord with saidknot abutting said wings.

3. A sack tie comprising a clip having a pair of Walls defining a recess, means for securing said clip to a part of a sack disposed in said recess, a lug outstanding from one of said Walls, a cord having a knot therein, means for securing said cord to said lug, and a pair of wings Outstanding irom the other of said walls, said Wings defining a channel therebetween adapted to receive said cord with said wings abutting said knot,

there being an opening 'between said wings into said channel inclined to the direction of said cord when extending from said lug around part of a sack and into said channel.

4. A tie for use with a sack comprising a single sheet of material folded upon itself to provide a recess defined by two substantially parallel walls adapted to lie on either side of a part of a sack disposed in said recess, one of said walls being bent to afford an outstanding lug, said lug having an opening therein, the other of said walls having its opposite sides bent toward each other to afford wings defining a conical channel therebetween, means extending into said recess from said walls to engage a part of a sack in said recess, and a .cord passing through and engaging the boundaries of said opening and said channel.
