BOX-SEAL.

Specification of Letters Patent.

Patented .J' une 22, 1909.

Application filed March 20, 1909. Serial No. 484,662.

To all whom it may concern:

Be it known that I, EDWARD J. Bnooxs, a citizen of the United States of America, and a resident of East Orange, in the State of New Jersey, have invented a new and useful Improvement in Box-Seals, of which the following is a specification.

This invention relates to the combination of metallic seal parts and box straps as means; for sealing wooden packing cases or boxesso as to insure the detection of any opening thereof for the abstraction of the contents.

Heretofore it has been customaryto unite the sealpart and box strap and to com lete the sealing-operation by means of a 119.1 driven through the seal part and stra ends, or through the latter at least, into t e wood of the box. This necessitated the location of the seal part on the box over an end or side of the box to rovide sufiicient depth of wood to receive the nail. Otherwise the seal nail I light do serious damage to the contents of the box. And it has been customary to arnm e' a sealed box strap over the row of nails in t e box proper at each of its ends.

Examples of such boxseals are set forth in my previous specification forming part of United States Letters Patent No. 847276 dated March 12, 1907, and previous specifications therein referred to, and in my previous specification forming part of an a plication for United States Letters Patent fi ed March 3, 1909, Serial No. 481201.

p In a companion specification forming part of an ap lication for United States Letters Patent ed March 19 1909, Serial N 0. 484,347 I have set forth means whereby to render such box seals nailless, and thus to provide for using a single box strap if desired with a single seal part located centrally on the box cover or on. the bottom or one of the ends or sides, or in any desired position, without endangering the contents of the box at the sealing operation.

' manner-set forth in said companion specification by means of metallic seal parts of more simple and inexpensive construction; and this invention consists in a'novel combina- .tion of parts and in an improved seal part of such simpler and cheaper construction as hereinafter inore particularly described and claimed.

A sheet of drawings accompanies this specification asport thereof.

Figure l is a perspective view of a wooden box sealed according to the present invention; Fig. 2 is a perspective view of the blank of the seal part represented in Fig. 1 as it appears beiore being bent; Fig. 3 is a perspective view showing the same blank with its first two bends; Fig. 4 is a )crspective view showing the four-bend seal part ready for use; Figs. 5 and 6 are sectional elevations illustrating the sealin operation; Figs. 7 and 8 represent magnified sections through the com leted seal and the su'bjacent portion of tive views of modified seal parts of substantially the same construction as the seal part shown in Fig. 1 and Figs. 4 to 8 inclusive.

Like reference characters refer to like parts in all the figures. v

I-n carrying this invention into effect a metallic seal part, a or a or a or a, and a metallic box strap, 1), are employed in connection with a wooden box portion, 0, and with a box-strap tool or tightener arts of which are represented at d, e and fin igs. 5 and 6, and a suitable sealing tool, 9, Fig. 6.

The seal part a or a or a or a, in each of its forms, is madeby bending a flat blank (11", Fig. 2), which may consist of a suitable length of the strap'iron which forms the box strap 1;, or may be cut from tin scrap or any The more brittle other suitable sheet metal. the metal the better, provided it will receive cold the bends hereinafter described and represented in the accompanying drawings, as any attempt to rebend any. portion of the seal part s ould result in its'mutilation' -and the1 disclosure of the attemptjt o, violate the sea "2:

In each of the species, the lateral edges, 1 and 2, of the seal part are formed from the ends of the blank (a by successive bends at right angles, all of which are readily formed in a bending machine at what is practically a single operation. The other edges or ends, 3 and 4, of the seal part are permanently open, and admit the ends 1 and 2 of the box strap 6 as in Fig. 1 and Figs. 5 to 8 inclusive.

In the s ecies represented by Figs. 1 to 8 inclusive t e blank a? is provided with a cenits edge and bottom portions formed y the. ends of the blank are symmetrical, under such length as to leave aspace, 6, beneathsaidcentering hole 5, as shown in Fig. 4.

',In the'species represented by Fig. 9 the blank is elongated at one end with reference to a centering hole 5, soas to form abottom 16 and overla ping the other end of the piece of portion, 7,substantially parallel with thetop of the seal part a, bent'inward from one edge metal at t e opposite edge'of the seal part.

' In'thespecies represented by Fig. the

seal art a is identical with theseal part a last escrib'ed,-exce..pt that itstop, 8, is without a centering hole (5, Fig. 9) which may in 1 some cases bedispensed with. In-thespecies represented b" Fig. 11, the

seal part athasa centering be e 5 in its top," iasin the first and secondspecies, and has two overlapping bottom portions, 7 and 9, ex-

metal for. the punch to penetrate in this-form as compared with the seal part a, Fig. 10.- Y 'The box strap E'rnay be cutfrom a-continu- '[o'u s length of. any suitable strap iron,'and requires norrelim'inary treatment.

, The tig tener represented .in'Figs, 5 and 6 '.is or may be of the construction set forth in said previous specification forming part .of

.said application, Serial No. 481201, and the parts. re resented in Figs. 5 and 6 are the slotted s aft of the tool, represented at d, a

cross bar of the frame beneath said shaft,

' represented at e, and a cross bar at the front edge of the frame, represented at f. For, the urposes'of the present invention said cross bar e beneath the winding shaft may be provided with a s ur, 10, which is driven through. one of t e box-strap'ends, 1, into the wooden box cover 0 to preliminarily and temporarily fasten the box-strap ,endfor the tightening operation. Otherwise the tool may be of the construction set forth in said previous specificationforming part of said application Serial No. 481201, or of any suitable known or improved construction.

The sealing tool g represented in 6 is or-may be an ordinary nail punch having a sharp tapered point, 11, a cylindrical or I equivalent portlon, 12, immediately abovev the same, and preferably, a stop shoulder,

13, by which the penetration of the point islimited; A

After passing the box-strap b loosely around the box (Fig. 1) in the desired position, both box-strap ends 1 and 2 are threaded through the seal part a or a? or a or a. The ti -htener de.f is then applied so as to drive its s ur 10 through one end, 1 of the box strap into the wood of the box cover 0, and thus to preliminarily fasten that box-strap end for the stretching operation. The other box-strap end, 2, being uppermost, is drawn beneath the front cross bar of' the tightener, and temporarily inter- ..locked with the shaft (1 by threading it through the slot of the latter and bending its extremity to resist withdrawal as represented in Fig. 5'. The shaft dis then turned in the direction represented by the arrow 0/, Fig. 5, until thebox-strap bis undersuffieient tension to embed it in the box corners, at least, as set forth insaid previous specification lastreferred to. Withthe box strap b under su'chtensiomand the seal part a or-a tool 9 is apfilied as in Fi 6, its point 11 be-. ing centere by means 0 said centering hole 5, and a blow on its u per end by means of a shank 12 of the sealing tool through the two strap ends, and through the seal art, and com letes thesealingoperation. he stroke 0 t e sealing-tool is represented by dotted Lacs in Fig. 6, and the effect of the tool,

is represented by Figs. 7 and 8." After removing the sealin tool g, the shaft (1 of the tightener is turned backward,as represented by the dot-ted arrow b in Fig. 6, to unwind the box-strap end attached thereto, the

loose box-strap end is cut ofl. close to the seal part as represented in Fig. 1. Referring to Figs. 7 and 8, itwill be seen that in the manner above described locking portions 11', 1.2- and 13,'of the two strap ends and of the to of said seal part a, are s1- multaneously ma e to project rigidly down.- ward at ri ht-angles to the top of the box cover 0, an to interlock with each other and with the wood of the box cover around .an

empty permanent indentation, so as to securely seal the box without the aid of nails driventhrough the seal art and box-strap ends as heretofore consi ered necessary.

, In the species represented by Figs. 9 to 11 inclusive, in addition to the lockin portion 13 represented in Figs. 7 and 8, 100 'ng portions of the bottom of the seal part would and the latter would be embed e in the wood of the box part c. A single sealed box strap may in the above manner be located between the ends of the box as in Fig. 1, or

top of the box, as there is no seal nail to be driven through the cover or like box part into the ends as heretofore. The box-strap and seal part may also, of course, be otherwise arranged and du licated if desired. The indentation by whic -one box-stra end is preliminarily fastened as above (lesc'li ed is represented at 14 in Fi 1, and the empty permanent indentation eft in thewood by the sealing tool 9 is re resented at 15 in Figs. 7 and 8. Instead 0- square, the seal parts 'tighteneristhen also removed,- and the or a or a in the desired position, the sealing hammer or the like rlves the point 1.1 and I which is immediately removed from the box,

obviously be formed at the sealin 0 eration between the sides or between the-bottom and different users may be;

may be oblong, "their closed edges or their open.-ed estlongest; those of fiere'ntly colored by dip ing' them insu'itab l'e pai'nt or'otherwise;

an other like modifications will. suggest themselves to those skilled in the art.

I do not claim herein the within described method of sealing wooden boxes without the aid of nails; nor, broadly,- the combination with a wooden box and a superposed metallic box strap under tension, having overlapped ends, of a metallic'seal part embracing the overlapped ends of said box strap and having a' portion parallel with said box-strap ends, said box-strap ends and said portionof the seal part parallel therewith having locking portions projecting rigidly at right angles to the subjacent surface of the box, and inter-' locked with each'other around an empty per- 'manent indentation in the wood of the box,"

whereby a nailless' box seal is formed but hereby disclaim the same in favor of said companion specification forming part of said application Serial No. 484,347 hereinbefore referred to.

Having thus described said improvement, I claim as my invention and desire to patent under this specification:

1. The combination with a Wooden box and a superposed metallic box"- strap under tension having overlapped ends, of a metallic seal part formed by. rectangular bends parallel with the longitudinal edges of said box stra over apped ends of the'box strap and a portion parallel with said box strap ends, said box-strap ends and said portion of the sealpart parallel therewith having-locking portions projecting rigidly at right angles to the subjacent box surface, and interlocked with each other, whereby a nailless box seal is formed. v

2. An improved metallic seal part for box seals, adapted to admit the overlapped ends of a box strap endwise and to embrace their lateral edges; such seal part being formed by parallel rectangular bends-and constructed and'having open ends to admit said with a to portion adapted to be interlocked v EDWARD J.
