j 1,625,772 Apnl19,1927. GMbLLER 1 SACK CLOSURE Filed Feb. 21, 1927 //7 van/er:

UNITED STATES PATENT OFFICE.
SACK CLOSURE.
Application filed February 21, 1927, Serial No. 170,022, and. in Germany September 22, 1924.
There are already known sack closures made of wire and so designed as to be adapted to be attached to the sack by a needle that is to be pierced through the sack fabric and then to be hung into a bow, whereas the closing proper of the sack is effected by another bow i. e., wire bow, that is placed around the tucked-in sack rim or the open end of the sack and then hung into a loop or eye. That known closure suitors from the drawback that it does not permit to compress or clamp in the tucked-in sack rim and to clamp fast the closure upon the sack so that the contents of the sack is not sufficient ly prevented from falling partly out of the sack when this latter is tilted or tumbles down, for instance while being forwarded. This drawback is obviated in and by the present improved sack closure in which the sack whose open end is closed by two wire bows of different size is kept securely closed by pressing one of said two bows against the other; the closure is so designed that its action is increased when the contents of the sack, in the case of the sack tumbling down or being tipped, falls against, and presses upon, the closure, as more fully described hereinafter.
The invention is illustrated diagrammat ically and by way of example on the accompanying drawing, on which Figure l is a plan of the members constituting the closure, Figure 2 an end-view thereof, and F1gure 3 a plan.
The sack closure consists of two differently large wire bows 1- and 2; each resembles in a certain degree a somewhat long n, the middle portion (10 and 7) of which is undulated. The ends of the how 1 form an eye 3 and a hook t. One end of the bow 2 terms also an eye 2 which is jointed to the eye 3 of the bow 1 in the manner shown in the lefthand lower corner of Fig. 1, and the other end of the bow 2 forms first a loop 5 the plane of which lies at right angles to the plane of the bow, and then a pivot 5 which can engage the hook t of the how 1 in the manner shown in Figs. 1 and 3. The loop 5 serves as a grip by which the bow 7 can be turned in the directions indicated by the arrows 6 and 9. The movement in the direction of the arrow 6 is bounded by the side portions of the bow 2 contacting with the inwardly curved portions 8 of the how 1. vVhen the two bows are connected with each other merely at 3, that is to say, when the closure is open, the bows can be placed around the tucked-in open end of the filled sack, then the pivot 5 is placed into the hook 4;, and the how 2 is turned towards the bow l by means of the loop or grip 5, so that the tucked-in end or rim of the sack is pressed and clamped in between the undulated portions 7 and 10 of the bows, whereby the sack is securely closed. Opening the closure is effected by turning the how 7 in the direction of the arrow 9 and disconnecting the pivot 5 from the hook 4. i
A particularly important feature resides therein that the side portions of the larger bow are not only crooked, as at 8, but also bent in a plane lying at right angles to said crooked portions and forming obtuse angles as in Fig. 2, whereby a clamping effect is obtained when the sack end has been inserted between the bows and the smaller bow is pressed so-to-say into said obtuseangles. The thus closed sack cannot get open spontaneously, nor open spontaneously when tumbling down, etc. It can be opened only in a positive way by turning the how 2 off the bowl 1 by hand.
The bows are preferably made of galvanized wire.
I claim:
A sack closure, comprising, in combina tion, two bows of practically El-SlittPQd form and of different size, and having undulated middle portions, the side portions of the larger bow being crooked inwardly and forming obtuse angles lying at right angles with respect to the crooked portions, and forming an eye at one end and a hook at the other end, and the smaller bow forming at one end also an eye which is-coupled with the eye of the first-mentioned hook, and at the other end a grip extending at right angles with respect to the plane of the bow, and a pivot adapted to engage the hook of the first-mentioned bow, substantially and and for the purpose set forth In testimony whereof I atfix my signature.
GUSTAV MULLER.
