May i5, 192g, Lmzm F. L. MCGARY DEVICE FOR APPLYING BOX STRAPS 5 34 .5 Original Filed notA 24, 1923 Illm humm I ,2 ATTORNEYS Patented May 15, 1928..


nnvrcn ron errante non sr A Application led october 2, 1923, Seal Ito. 670,363. Renewed September 21, 1823.'

rIhis invention relates to devices for applying box `straps or barrel hoop seals of the type described and claimed in my Patent No. 1,517 ,515; December 2, 1924.

Box strap sealing implements have been .-ro constructed that it is necessary to insert a portion of the implement beneath the box strap whereby the straps are raised so that utter the seal has been locked in place upon the overlapping strap ends by the operation of the implement tliestraps are not rigidly bound about thevbox. Such loose application ot the straps permits the straps to shift I(amd in ed'ect do not act as a binder for said ores.

' It is .an obj'ectfof my' invention to provide a device for simultaneously deforming porF tions of the longitudinal side edges o the overlapped ends of a box or barrel strap in `such a manner that the strap will be in rigid engagement with the container to which Ait has been applied throughout its entire4 length so that there will be no shifting or looseness v Ain the strap when the ends have been sealed.

A'urther .object ot' my invention is the provision of a device Afor readily applying seals to loverlapped strap ends whereby said ends are locked against movement with the stra in rigid clamping engagement with the iiox, the implement beingadapted to* cut upturned lips either in both the seal, and the overlapped strap vends or portion of the side edges ot' the overlapped strap ends may be sheared to provide upturned lips to project upwardly through slotted portions of the usual sealin sleeve. A

Another o ject 4of the invention is the provision of a device for gripping only the longitudinal side edgesV ot they overlapped ends of a box or barrel strap and for readily shearing tlie saine by an upward cutting of the material when the device is operated, thereby forming upturned lips on the strap ends or simultaneously forming upturned lips4 of the strap ends together with a sheared and upturiied portion of the sealing sleeve embracing said lips.

This invention will be best understood from a consideration' ot the following de tailed description in view of the aecompanying drawing forming a part o the specication; nevertheless it is to be understood that the'invention is'not coed to the disclosure', being susceptible oi*V 'such i changes ande-modifications which shall-demie no material departure from the salientfeatures of lthe invention as expressed in the appended claims.

in the drawings:

Figure l is a plan view ot the bofxfstrep' sealing implement. v v

Figure 21s e. fragmentary view in hori- --Azontal section showing details oi the imple.


Figure 3 is a side view of the same. Figure 4' is a view in perspective of one form of sleeve locked to the overlapped ends of the box strap by means of theydevice illusportions of the overlapped strap ends.

-Referring to the drawings, l and 2 designat-e handles which have enlarged portions 3 at their upper` ends. Said enlarged.` portions are provided with soclr'ets d. The.

socket 4 at the upper end of arm 1 isadapted to receive a linlr 5 p ivoted on a pin 6 mounted in theenlergement of the arm. A

vlinlr 7 received within the socket 4 of the arm 2 is pivoted at 8 on a pin mounted in the enlargement ot said arm.

The upper end of the li lr 5. is biturcated as at .9 to receive the upper end 1G ot' linie 7.' Apin llpivotally connects the upper ends of'these links. A toe 12 projects inwardly from the lowerl end of link 5 while a toe 13 projects inwardly from the lower end 'of link 'i'. @ne edge oit' the toe l2 is engaged by the inner end ot a set screw lll which is screwed into o. threaded passage in the arm l. A set screw lis screwed into a threaded passage in the arm 2 and has its inner end iii engagement with the toe 13 of link 7.

The rear edges of the links 5 and i' are each engaged by a set screw 1'6 which are screwed into threaded passages in the respective armsl and 2. 'llie lower end of a toggle lever i7 is pir/Totally mounted at 18 in 'the biiercated upper end oi the arm i while a toggle lever i9 is pivotally mounted on the bfurcated upper end ot the arm 2 on a pin 20. The intermediate portions of dit the toggle levers 17 and 19 are pivotally connected to front and'rear plates-21My means of' bolts 22. vThe intermediateportions ofthe levers` 17 and 19` adjacent 'the bolts 22 are provided with inwardly projecting members 23 which have cooperating teeth 1n engagement-with each other for a purpose which -will'be presently explained.'

A bolt 24 rigidly locks the plates 2 1 together. '.lhe upper'free ends of the toggles 17 and 19 are'fprovided with jaws 25 which project-towards eachother and are adapted to cooperate with the outer edges 26` o f the "plates 21 to deform orshear the'metal of the sealing sleeve and the longitudinal side edges of the strap ends embraced by said sleeve. 'The jaws and the outer edges 26 of .the plates Aform the die for deforming the metal of the. sealing sleeves and overlapped ends of the straps. 'Each of the links 5 and 7 are provided withribs 27 which project laterally from opposite sides of the links and are adapted to .engage the inner edges 28 of the upper ends of theaims 1 and' 2 and limit the inward movement of the links within their sockets 4.

Fi ures ltand 5 discloselthe sheared seal.

ing s eeves and overlapped strap ends described in my patent mentioned above. e The sleeve 29 is provided with slots 30 and designates the point atvwhich the strap ends 31 land 32 `areto be lsheared so thatwhen the tool engages the longitudinal side edges of the strap' ends at this point the metal of thestrap ends will be raised upwardly to form lips 33, and Vtherehylock the strap ends and seal as a unitary structure. vThe sleeve 34 of .Figure 5 is devoid of the slots30 so that theA toolwhen engaged with the sleeve will not only form elevated lips 35 of a portion of the side .edges of4 the strap ends but -will also raise aportion-36 ofthe sleeve inem .braced relation with the lips 35. The arms 1 and 2 are rovided with perforated bosses 37 adapte tol receive pins 38. The outer ends ofthe pins are provided with heads 39 which are' adapted to abutwhen the arms 1and 2 are moved toward each other., Elastic sleeves 40 vare mounted on 'thegpins 38 and between the heads 39 and the inner ends of the bosses 37 andare ada ted to -be-y compressed when pressure has een applied to the arms 1 and 2 for moving the.

armstowardv each other. The elastic material of. thegsleeves 40 forces the arms apart when pressure has been relieved from saidarms. y v The operation of my device is` as follows:

\ Before applying the device to a sleeve embracing an `overlapped strap end, the links 5 andv 7 must be adjusted to properly space the jaws25 in order that the jaws will sufficiently shear the metal of the sleeve and the'overlapped strap ends .for locking the sametogether. If it is desired to space the jaws l25 fartherv apart, the set screws 16 are adjusted outwardly for removing their inner ends of links 5 and 7, while the set screws 14 and 15 are screwed inwardly respectively against thetoes 12 and 13 of the set screws 16. The reverse movements of the set screws brings the jawscloser together. The lever arms 1 and 2 are then moved outwardly from each other to sulicientl spread the jaws 25 from each other in order to be engaged around either the sleeve '29 or the sleeve 34. The ends25 of the jaws engagel around ythelateral edges of the sleeve while the outer ends 26 ofthe plate 21 rest upon the upper surface of the seating-sleeves. The arms 1 and 2 are 4:forcibly moved -toward each other whereby the side edges of the sleeve-34: together with the portions of the overlapped strap-ends are sheared and moved upwardly between the plates 21by the cutting jaws 25. Where the device is applied to the sleeve 29 the jaws 25 are litted within .the slots 30 and, those .portions of the overlapped strap `ends31 and 32 conlined within the 'slots 30 are engaged by the jaws 25 while the outer edges 26 of .the lates 21Vrest upon the'upupwardlyfth'roughf the slotted 'portion 30 of the sleeve 29 and thereby lock the sleeve and the strap ends together. 7

v`It will be noted with my device that the stra ends are at no -time elevated above the ox or barrel when the stra is being applied so that the strap will be a ways taut an in .rigid engagement with the container to 'which 1t has been applied. The jaws cooperating with the outer edges of plates 21 merely `serve to deform edges of the overlappe straps in the case of .the sealing device shown in Figure 4 .while in Figure 5 the metal lof the sleeve 34 together with the adjacent portions of the `side edges of the overlapping straps -are sheared and' locked in cooperative engage ment and this is done without elevating the strap at the point where the slot is applied.

The jaws of the die have an upward shearing action while the outer edges of the plates 21` press downwardly on the sleeve and strap ends and aid in maintaining the` strapends against displacement and thus prevent .loosening `of the strap. During the cutting action of the jaws, the cutting edges of said yjaws move -into 'shearing contact with the outer edges 23'of the plates 21 whereby the metal of the assembled sleeve and strap ends are sheared and forced inwardly of the outer edges of the plates.

The plates 21 act not only as a mounting for the jaws but provide a housing for the ortions of the side temeer same and instead of the plates a' housing overlapped' strap ends between the jaws,

with the outer face of the sleeve engaged ,by the outer ends of the plates, andmeans connected with the jaws for causing said jaws to be moved inwardly of the housing whereby the metalv of the assembled sleeve and*4 overlapped strap ends are sheared and forced upwardly from the object to which the strap ends have been applied.

2. A. device of the character described comprising ahousing, a pair of spaced jaws pivotally mounted in the housing with the biting ends of the jaws sutliciently projecting beyond vthe outer end of the housing Vto receive an assembled sleeve and overlapped strap ends between the jaws with the inner adjacent faces of the jaws engaging the opposite side edges of the assembled sleeve and strap ends,jthe outer end of the housing resting upon the top of the sleeve, and

means connected'with the jaws for causing said jaws to be moved inwardly of the housing whereby the metal of the assembled sleeve and overlapped strap ends are sheared and forced upwardly. v

v 3. A device for applying box straps comprising a pair of spaced plates,a pair of jaws pivoted on and between the plates and having V-,shaped ends adapted to project l beyond the outer edges of the plates, the

outer edges of the plates forming a fulcrum for the device and engaging a box strap when said strap is acted upon, means for, causing movement of the V-shaped end inwardly of the plates.

4.A A device for applying box straps comprising a housing, a pair of similarly formed toggle levers pivotally mounted intermediate the ends thereof inthe housing, eachof Vthe levers being provided with a jaw projecting beyondthe outer end of the housing, with the jaw of one lever facing the jaw `of the other lever, the outer/end of the'lousing forming a support for the device when the same is operated and, adapted vto rest upon the box'strap, said jaws being movable into the housing, and means for moving the jaws into said housing.

5. a device for applying box straps comprising a housing, a pair of levers pivoted in the housing and provided with jaws projecting beyond the outer end of the housing to engage box straps, said jaws being movable wit-hin thevhousing when the `levers are opera-ted for cutting and forcing the cut portion of the box strap into the housing, and means for operating the levers.`

6. A device for applying box straps comprising a pair of plates, .jaws pivotally mounted on and between the plates and provided at their inner faces with cutting edges, said jaws normally projecting beyond the 75 outer'ed'ges of the plates to receive simultaneously the opposite side edges of an assembled sleeve and overlapped strap ends, and means connected with the jaws for causing the cutting edges to Abe moved into shearing Contact with' the outer edges of the plates whereby the metalof the assembled sleeve and strap ends are sheared and forced inl wardly of the outer edges of the plates.
