(Cl. 292—315) This invention relates to improvements in seals advantages by which seals of this general kind for preventing unauthorized opening of boxes commend themselves in use. or receptacles the covers of which are fastened Other objects of this invention, not at this in closed position by means of cooperating hasp time more particularly enumerated, will be un and staple elements. derstood from the following detailed description 5 “Seals of the kind mentioned are applied of the same. through the staple to overlie the outer face of An illustrative embodiment of this invention is the hasp through which the staple projects. The shown in the accompanying drawing, in which:— seal is usually made of generally circular but Fig. 1 is a face view, Fig. 2 a top edge view, and 10 discontinuous conformation, and is provided at Fig. 3 is a side edge view of a hasp seal made one side with a permanent lateral enlargement according to the present invention; and Fig. 4 ‘of a width exceeding the internal dimensions of is a transverse sectional view of the same, taken the staple opening, and at the other side with on line 4—-4 in Fig. 1. a deformable portion initially of a width sized Fig. 5 is a front elevation of the hasp and staple to readily pass through the staple opening, but portions of receptacle to which the novel seal 15 adapted to be deformed or laterally enlarged by of this invention has been applied and impressed; ‘a suitable tool or press, after it is passed through the staple opening, so that its width is increased to a dimension exceeding the in ternal dimensions of the staple opening, where by it cannot be drawn back through the latter and thus disengaged from sealing relation to the engaged hasp and staple. Seals of this type are expected, when once operatively applied to an assembled staple and hasp fastening means, not to be removable except by breaking and thus destroying the same, whereby, when once re moved, the same cannot be again used. It has been found that in some instances seals 30 of the kind above described can be violated by Mbending and folding or doubling the same upon themselves without removing them from the staple, and thereupon forcing the doubled or folded together portions through the slot of the 35 ‘hasp element by prying the latter off of the staple and over the doubled or folded seal parts. Under such circumstances the receptacle could be surreptitiously opened, its content stolen, -. and thereupon the hasp could be forced back 40 over the doubled or folded seal and onto the staple folded shape, would 45 again, and the seal thereafter be un and ?attened back to normal initial so that little evidence of the tampering appear, and might easily be overlooked .unless a very critical inspection and examina tion of the seal were made. It‘ is'an object of the present invention to pro ‘ vide a seal of the general type and‘kind above ‘described, but ‘so improved in form andstruc ture that adequate safeguards against tamper ing and possible violation by folding or doubling or like surreptitious manipulation is afforded, while yet retaining all the advantages of ease 55 of initial application, simplicity of form and like and Fig. 6 is a side elevation of such assembly. Fig. 7 is a front elevation similar to that of Fig. 5 but showing the seal doubled or folded on itself with its parts back to back, this view illus trating the futility of this method of manipula tion in attempting to violate the seal by forcing the slot of the hasp thereover; and Fig. 8 is a similar view showing the seal doubled or folded on itself with its parts face to face, this view showing the futility of such method of manipu lation in attempting to violate the seal by forc ing the slot of the hasp thereover. Similar characters of reference are employed in the above described views, to indicate corre sponding parts. In the drawing, the reference character I in dicates a receptacle having a forwardly project ing staple 2. The open top of the receptacle is closed by a cover 3 with which is suitably con- ; nected a hasp 4, the latter having a slot 5 to engage over the staple when the cover is closed and secured. The receptacle and cover with the cooperating staple and hasp elements, as shown, is merely illustrative of one of many forms there 40 of to which the seal of the present invention may be applied, and consequently is subject to con siderable variations as to specific construction and as to the use to which it may be put, and as to devices with which it may be associated. The seal of this invention is applied to the staple and hasp elements to prevent unauthorized separation thereof and consequent opening of the receptacle for unauthorized access thereto. The seal device is used in place of a padlock, 01 O cross-pin or like means usually employed to se cure the staple and hasp against separation. In an illustrative and preferred form thereof, the seal according to this invention comprises a unitary body formed from sheet metal, e. g. 55 2 2,105,524 steel, and is of substantially circular but dis inspection of Figs. 7 and 8 of the drawing. If, continuous form so that a gap @ is provided be for example, the seal arms are bent across the tween opposed terminal portions ‘l and 8 thereof. weakened portion 9 by which they are joined, so The gap 6 is of sufficient width to permit in- . as to fold the seal and bring the arms back to At back, as shown in Fig. 7, the transverse stop shoulder 51 at the inner end of the guard ?ange l5 of seal .arm it will be disposed crosswise of a point diametrically opposite the gap 6 the seal the hasp slot 5, and will immediately arrest any ward passage therethrough of a leg of the staple 2, whereby the seal may be inserted through the eye of said staple so as to hang therefrom. movement of the hasp over the thus folded seal body is provided with a reduced or weakened por~ 10 tion 9 formed by an internal indentation or ~ arms, and consequently such an attempt to notch H3. Extending in opposite directions from violate the seal will be fruitless. On the other said weakened portion 9 are the substantially . hand, if the seal arms are folded together so as semi~circular arms H and I2 of the seal body. to bring the same face to face, the stop-nosing I6 The arm 8! is so shaped, initially, as to possess of the guard ?ange l5 associated with the arm IE‘ will abut the inward part of the concave 15 15 a concavo-convex shape in cross section at the portion l3 thereof lying between the weakened conveX portion it of the arm H so as to obstruct portion 9 and the terminal portion "1.. Said arm ll, as thus formed, is of an initialuniform width throughout its extent somewhat less in dimension 20 than the size of the eye of staple 2. . The arm (2 is preferably‘ uniformly flat throughout its extent, but is provided inter mediate the weakened portion 9 and the terminal 8 with an outwardly extending laterally widened 25 part forming a stop-portion It of 'a width ex .ceeding the size of the eye of staple 2. In tegrally formed in connection with the inner curved margin of said arm E2, to stand upright or at right angles to the face plane of the latter, 30 is a general flange 95. Preferably this guard ?ange is widened at its inner end to form a laterally projecting stop-nosing is adjacent to such inner end, and the end itself provides a stop shoulder ll transverse to the plane of the 35 and prevent the meeting of the front faces of said arms, and consequently the width of the forma tion will not be reduced suf?ciently to allow the slot 5 of the hasp 4! to be stripped thereover (see 20 ‘Fig. 8) ,' and consequently such attempt to violate the seal will likewise be frustrated. Owing to the fact that the guard ?angev I5 is curvilinear in vertical plane, since it projects from the inner and substantially semi-circular margin of the arm} l2, it is quite impossible to ?attendown the same smoothly into the plane of the seal body, and consequently such method of attempting to bring , . the seal arms in ?at folded together relation can not be successfully resorted to. When it is desired, by an authorized person, to open the receptacle which is guarded by the seal, the arms 5 i and I2 are grasped and spread apart, and the seal so manipulated ‘as to break the arms seal. Said guard ?ange i5 preferably tapers apart at the weakened central'portion 9 between 35 from its inner end toward its outer end, although the arms. thisis not essential. destroys it so that it cannot be used 'again. , . This not only removes the seal, but In applying the seal to the receptacle, after When the receptacle is again closed and secured, the hasp 4: is engaged over the staple 2, the arm 40 H is inserted through the eye of the staple, whereby the seal is suspended from the latter with one arm, as l I, depending at one side of the staple, and the other arm, as 12, depending from the opposite side of the staple (see Fig. 5). After the seal is thus inserted through the 45 staple 2 exteriorly of the hasp 13, a suitable press is applied to the concave-convex section It of the arm M, and by the press action a portion of a new seal must therefore be applied in guarding said concave-convex section it is crushed down 50 or deformed so as to be ?attened and widened out, as shown at is in Fig. 5. The ?attened and . widened part 58 provides a stop-section, the width of which exceeds the internal sizeof the eye of 55 relation to the staple and hasp. 040 Having now described my present invention, I claim:—- . 7 1. A seal for extension through a staple and. exteriorly of a slotted hasp closed over said staple comprising, a body having arms extending in a;_45 common plane but in opposite directions from an intermediate portion thereof, one of said arms having an outwardly extending widened section in the plane thereof to prevent passage of said arm through the staple eye, the other of said, arms being of an initiallwidth adapted to pass through the staple eye, said latter arm having intermediate its ends a deformable portion adapted to be pressed to provide a widened stop, the staple, and consequently obstructs any at tempt to withdraw the seal arm I l back through portion to prevent retraction thereof through the, the staple eye so as to remove the seal from the staple eye, and said ?rst mentioned arm having a The stop-portion i it formed in connection guard ?ange extending along its inner margin with seal arm 82, being wider than the internal and projecting angularly from the plane .of said ~ staple. size of the staple eye, inlike manner obstructs 60 any attempt to draw outwardly from the staple eye said seal arm l2, thus preventing removal of the attached seal in such manner.’ » As hereinbefore stated, it has been attempted to violate seals of the general type here involved, 65 by bending and folding together the two semi circular arm parts thereof, and then prying up the hasp in such manner as to force the slot 5 of the latter over the thus folded arm parts, thus freeing the hasp from the staple. Attempts to so violate the seal of the instant invention will 70 be quickly frustrated, as will be obvious from an arm. ' ,2. A seal as de?ned in claim 1 wherein said 60 guard: ?ange terminates at one end in a stop shoulder disposed adjacent to the intermediate portion of said seal body, said stop shoulder ex ceeding in dimension the width of the hasp slot. 3. A seal as de?ned in claim 1, wherein said guard ?ange terminates at one end in a stop shoulder disposed adjacent to the intermediate portion of said seal body, and said ?ange having an outwardly projecting stop-nosing. at the juncture of its free edge and said stop shoulder. 1 'EMIL DIETZE.
