This invention relates to cutting and formdevices.

t relates more particularl to a device for ly those composed of elastic compressible material, it has heretofore been the common practlce to encircle a package with one or more metal bands while the material is under compression, to overlap the flat ends of the band or stra and then, usually with the aid of an encirc ing metal sleeve, rmanently to join the overlapping band en s to form in effect a hoop or loop around the package. Thus when the compression is partially or wholly released the hoop-like band or bands hold the material tightly-in a package. The general appearance of a package ,of'this kind and of a sleeved seal-joint for uniting the overlap in band ends is illustrated, .for example, 1n lora PatentNo. 1,252,680, and Leslie Patents Nos. 1,437,525 and 1,445,330.

Considerable trouble has been ex rienced heretofore in the pre aration or ormation the band ends could be of such packages due m part to the difliculty of maintaining the overlapping band ends and encircling sleeve in proper relation until permanentl joined and in part due to the difliculty of obtaining and maintaining the requisite and uniform initial tightness of the bands about the material under compression to insure substantially uniform tension when the compression is partly or wholly released and thereb produce substantially firm, symmetrica and equal-sized packages.

The foregoing difficulties have been 'overcome by a method of forming packages proposed by Ernest G. Pagel and which is set forth in his application Serial No. 466,053, filed July 7 1930. The method proposed by Mr. Pagel contemplates the formation of complementary pro'ections and depressions in the overlapping and ends which may be temporarily interengaged, preferably with.

the assistance of an, encircling joint-reinforcing sleeve, so that the band ends of one or any number of encircling straps may be easily, quickly and accurately temporarily united and. will remain so united, as long as the bands are not subjected to any substantial tension, until the been made therebetween.

Our invention relates to a forming and cutting device, particularly although not necespermanent'joint has I sarily adapted to embodiment in a handoperated tool, whereby encircling straps or bands of the desired length may be easily and'quickly cutfrom a bundleor reel of band material and at the same time the two ends of the band in the region of severance are simultaneously formed to provide the comple-- mentary interengaging projections and depressions for temporarily interlocking the ends as previously set forth.

One of the objects of our invention is to 7 provide a device for simultaneously severing and forming both severed ends of metal' Another object is to provide a device which simultaneously cuts a band and forms the ends thereof, adjacent the cut, into complementary projections and depressions adapted tointerengage to retain the ends together when overlapped.

Another object is to provide 'a device of the character described in the form of. a simple,'reliable, effective and easily operable hand tool.

The jaw 16 is (provided with similar recesses 19 and 20 a j acent the lateral edges of the jaw. On the jaw 15 are provided depending lugs or extensions 21 and 22, which are narrower than the recesses 19 and 20 and are disposed centrally thereabove in such relation thereto as to press portions of a metal strap downwardly thereinto and form corrurugating element 21 and are therefore adapt- 'gations in the strap as shown in Fig.3.

Intermediate the corrugating elements 21 and 22 are provided cooperating cutting shoulders 25 and 26 which are nearer the corrugating element 22 than they are to the cored to sever the metal strap 27 at a point as shown in Fig. 3, which is relatively close to the corrugated portion 29 and at a greater distance from the corrugated portion 31 and resulting in the production of two strap ends 32 and 33 having the corrugated portions 29 and 31 as shown in Fig. 4 with a relatively long extending portion 35 on the portion 32 and beyond the corrugated portion 31 thereof.

The utility of the metal strap thus formed is clearly illustrated in Figs. 5 to 8 inclusive. In F ig. 6 is shown a sleeve 37 of such dimension that it may be threaded onto the end portion 33. It is threaded onto the portion 33 a suflicien't distance so that the'portions 33 and 32 may be lapped one upon the other in the manner shown in Fig. 7 with the complementary corrugated portions inferengaged, after which the sleeve is moved downwardly to the position 'shown in Fig. 8 with relatively short portions of the strap ends extending therefrom, which portions are not the strap ends 32 and 33 forming a seal ofthe general shape indicated at 39.

It will be understood by those skilled in the art that other devices may be formed which will accomplish the objects of this invention and we desire, therefore, to avail ourselves of such other forms and modifications as come within the scope of the' appended claims.

We claim as our invention:

1. A device of the class described comprising two relatively movable members, cooperating jaws on said members adapted to receive a metal strap therebetween, one of said jaws having recesses therein adjacent its lateral edges, projecting portions on the other jaw disposed opposite the recesses and ada ted to depress ortions of'astrap thereinto or corrugating t 1e same, and cooperating means on said jaws intermediate their edges for severing a metal strap positioned therebetween.

2. A cutting and forming tool comprising two cooperating jaws having forming elements thereon adapted to engage and form corrugations in a metal strap placed therebetween, and means .for severing the metal strap intermediate the points at which the corrugations are formed.

3. A forming tool of the class describedcomprising two cooperating members pivotally secured intermediate their ends to form.

hand grips and jaw supports, cooperating jaws removably secured to said supports, means on said jaws for clipping a metal strip placed therebetween, and means for holding and forming complementary corrugations on the metal strip adjacent the severed ends.

4. A device of the class described comprising two relatively movable members, coopcrating jaws on said members adapted -to receive a metal strap therebetween, one of said jaws having recesses therein adjacent itslateral edges, projecting portions on the other jaw disposed opposite the recesses and adapted to depress portions of a stra thereinto for eorrugating the same, an metal cutting means on said jaws adapted to sever the metal strap intermediate the corrugations formed therein and relatively nearer one corrugation than the other.

5. A band cutting and forming tool comprising oppositely disposed cooperating jaws adapted to receive a metal strap therebetween, and including means for forming two similar corrugations on the strap, means on said jaws for severing the strap between the corrugations and nearer to one corrugation than the other, and means for actuating the ]&WS..

- 6. A-combined strap cutting and forming tool comprising two actuating elements pivoted together intermediate their ends, forming arallel extending handle grips and positive y disposed jaw supports, removable aws secured to said jaw supports and adapted to be actuated into cooperating relation, said jaws including means for ormin spaced deformations on a metal strap p aced between the jaws, and cooperating1 cutting portions disposed to cut the strap a jacent one of the corrugations and a spaced distance from the other corrugation, thereby providing a relatively long extension on one of the severed ends of the strap toward the end from the corrugation thereon. l5 7 A device of the class described comprising a pair of relatively wide jaws adapted to interengage face to face, said jaws being provided with cutting edges adapted to sever a metal strap placed between said 'aws, and m with die elements on either side 0 said outting edges adapted to produce 1 ransverse corrugations on the strap at the same time as the cutting operation.

8. A device of the class described comprising a pair of relatively wide jaws adapted to interengage face to face, said jaws being provided with cutting edges adapted to sever a metal strap placed between said jaws, and with die elements on either side of said cutting edges adapted to produce transverse corrugations on the strap at the same time as the cutting operation, the die elements on one side being located nearer the cutting edges than the die elements on the other side. 9. A device for forming and severing metal package-binder straps, comprising a pair of relatively movable aws having cooperating cutting means for severing the strap and cooperating deforming means flanking the cutting means on each side for forming complementary deformations in the severed ends of the strap.
