Application filed January 10, 1926. Serial No. 350,544.

son and State of New Jersey, have invented certain new and useful Im rovements in Wire-Strap Seals and Meth s of Forming the Same, of which the following is a full, clear, and exact description.

Among the principal objects which the present invention has in view are: To form a substantial fastening for wire straps used for binding boxes, 'bales, and similar articles; to secure the ends of the stra and to seal the same quickly; to draw tlie strap tightly on the object bein packed; and to provide a seal which mayie fastened while the wire strap is under maximum tension.


I Figure 1 is a view showing end fra ments of a strap united b means of a seal constructed and arranged in accordance with the resent invention;

Figure 2 is a view of an and fragment having an open spiral coil which when enclosed forms the seal; and

Figure 3 is a view showing the open coil with the straight end of't he strap Inserted therein prior to closing the coil.


Wire straps are used for securing packing cases, bales and other articles, and to that end are passed around the case or article, and the ends are drawn together and secured. The object in view is to draw the wire as securely as possible around the case, and to fasten the ends permanently and ,strongly without slacking or relieving the tension on the wire.

, With this object in view the present inven;'

drawings where the free end 13 is in line with, a shown as in the" act of being in troduced through, the loops 10 and 12.

In Figure 3 the disposition of the free' end within the loops of the spiral is shown. In thls position the end of the wire strap having the spiral is drawn in one direction, whilethe free end 13 is drawn in the oppo slte direction, to bind the wire strap on the article being packed. When the strap has been drawn tightly, the coils of the spiral are pressed or flattened until the sections of the spiral beneath are forced upward, while the other sections above the portion 11 and end 13 are pressed downward with the effect that the said portion 11 and end 13 are crimped or waved by being displaced by the pressure up bed to the portions of the spiral.

s shown in the drawings, the spiral is so open that the under and upper portions are removed from each other, so that the wire forming the portion 11 and the end 13 ma move in accord with the pressure applie When the portion 11 and the end 13 have been crimped, as shown in Figure 1 of the drawings, theend 13 cannot be drawn from the seal without straightening the coils and the wire itself, to do which the strain on the strap is insuflicient.

The spiral may 'be flattened by any suitable means. The sections may be hammered on an. anvil slipped below the seal, or an apparatus may be usedto' formthe seal such as is disclosed in a co-pend'ing application filed the 10th! day of January, 1920, Serial No. 350,545, to which application cross reference is here made.

When the seal is perfected the coils and engaged wire are flattened to approximate the thickness of two layers of the wire. The seal being flat, rests snugly on the packing case to avoid catching or snagging other articles. The excess wire of the free end 13 is clipped close to the inner end of the seal.

While I prefer to form the spiral of the wire'strap 9, and inte a1 therewith, I may use a short section 0 spiral formed separately.. Other forms of separate seals may be used having upper and lower bars held in spaced relation and staggered substantially as shown in the drawings. Through these various forms, both ends of the wire strap 9 may be extended before the spiral is closed thereon to crimp the said ends, and thereby hind or seal the strap.


1. A wire strap and seal therefor com rising a continuous double ended wire having at one end,a portion thereof returned upon itself in open spiral ooils enveloping said wire to form a passage for the opposite end of said wire, the ends of said wire being crimped upon the sections of said coil.

2. A wire strap and sealtherefor comprising a continuous double ended wire having at one end a portion thereof returned upon itself in open spiral coils enveloping said wire to form a passage for the opposite end of said wire, the ends of said wire bein cnimped upon the sections of said coil, said c-rimped portions and coil forming a. relatively fiat structure.

- 3. A wire strap having at one end thereof an open helix integral with and enfoldingr the adjacent straight portion of said wire,

said helix beingofl'set in relation to the en-v foldexl strai ht portion of said wire for holding said straight portion against the sides of said helix to provide a. passage for the opposite end of said wire between the said straight portion of said wire and the opposite side of said helix.
