To all whom it may concern: 7 I

Be it known that 1, ROBERT L. CAL AHAN, a citizen of the United States, residing at Louisville, in the county of Jefferson and State of'Kentucky, have invented certain new and useful Improvements in Means for Fastening sacks ofwhich the followingjis a specification. 1

My invention relates to means for fastening sacks after the same have been filled with grain, flour or other substances. It is the object of my invention to provide fasener mechanism which mayeasily be applied to the open corners of sacks which have previously been sewed across the top so as to leave only comparatively smallopenlngs at the corners. My invention provides means for quickly and securely closing these openings, and at the same time forming ears for the handling of the sack, by merely slipping said means down: over the corner which is gathered together adjacent said opening. Various types of devices may be employed for this, purpose but comprise primarilya ringwith an opening in the 'center said opening being so formed or having ts edges so formed as to adapt thering to be slid in one direction along the gathered sack corner and to restrain movement of the ring in the opposite direction and also to hold the ring in its inward position on the gath ered sack corner where said corner is clamped together by the ring so as to effectively close the opening.

The full objects and advantages of my invention will appear in connection with the detailed description thereof and are particularly pointed out in the claims.

In the drawings, illustrating the application of my invention in one form,

Figure 1 is an elevational view of a sack being filled. Fig. 2 is an elevational view of a filled and sealed sack. Fig. 3 is a plan view of the stock out of which my fastener is made. Fig. 4 is a plan view of a finished fastener drawn to full scale. Fig. 5 is an elevational sectional view of the fastener shown in Fig. 4, and Fig. 6 is a full size detail of a corner of a sack sealed with my novel fastener. Fig. 7 is an elevational view of a slight modification of the fastener shown in Figs. 4 and 5. Fig. 8 is a perspec- .tive view of another modification of the same, and Figs. 9 and 10 are plan and elevational views, respectively, of a third modifi;

.91 the ame The sacks 10 may be of any desired size or shape and constructed of any fabric material commonly used for sacks, such as jute, burlap or cotton bagging. Such sacks formed in the ordinary manner are partially v closed across the top, asv indicated at 14:.

leaving openings 15 at each side of the closed 4 portion; or in the upper corners 16 of the sacks, which openings are adapted to receive filling spouts 17 through which the grain, flour, lime, cement, salt, sugar. or other material which it is desired to inclose within the sacks may be introduced. The filling of the sacks 10 may beaccomplished in any well-known manner or by means of a special process andapparatus devised by me and for whi'ch protection will be sought in another application.

After the same has been filled with the requisite quantity of material the .corners of the sack are gathered together so as to form ears and such gatheredcorners arcinserted through a circular fastener member 18, a preferred form of which is shown in Figs. 3 to 7, 1nclus1ve. Such a fastener member is primarily formed of a circular disk of metal having transverse slits 19 cut in the same, as indicated in Fig. 3, the intervening material being pressed up to form inwardly-projecting pointed tongues 20 surrounding a central opening 23. A flat portion 21 of the disk may be provided with a flange 22 to increasethe strength of the same and the fastener may be cut, as shown in Fig. 7, so as to form small pointed tongues 24 at the base'of the longer tongues 20. Other forms of fastener devices of a generally similar nature may be employed, such as those shown in Fig. 8 and Figs. 9

I and 10. L In each casethere would be provided a closed ring with a central opening provided with some form of sack engaging member. As in Fig. 8, a disk of metal is formed with an elongated pointed opening 26, having preferably toothed walls 27 and 28, the acute angles of the ends of the opening 26 providing means for holding the fabric of the sack by wedging the same therein while the teeth will hold the sack by engagement within the body of the fabric. In Figs. 9 and 10 is shown a fast ener made of twisted wire comprising a ring 30 formed of the untwisted portions of the wire and prongs 31 formed from loops of said wire set up from the ring and out across. The jagged. free ends fill rv ire 1 5 of the sacks will be gathered together to formears 32. and the fastener. member 18 is slipped over the gathered ear and pressed with the hand tightly down upon the body of grain at the base of the ear.

This results in compacting the ear so as to completely close the opening into the sack and the fastener remains in position because of theengagement with the fabric" ofthe ears of theprongs and angles formed around the opening in the fastener.

.Thead'vantages of'my invention will be apparent. No'seWing ortying of the sack after filling; is required. The double opening on' each side of the sack permits ready filling; and" the application of the fasteners to. the ears inthe manner described-not only closes these openings'but also provides the ears'for'handling the sacks. It Will further be apparent that the fasteners may be applied'witlnthe utmost ease and despatch, and may'readily be'remove'diby turning back the prongs or edges with a knife or bar, or by cutting'the' fastener with a shear or other wire or 1netal-cutting instrument.
