UNITED STATES EMIL TYDEN, OF EVANSTON, ILLINOIS.

BAG-TIE SEAL-LOCK.

Application filed January G, 1921.

T 0 all whom t may concern Be it known that I, EMIL TYDEN, a citizen of the United States, and resident of Evanston, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bag-Tie Seal- Locls, of which the following is a specifi cation, reference being had to the accompanying drawings, forming a part thereof.

The purpose of this invention is to provide an improved device for securing a bagtie adapted to be sealed or secured bv a flangible or rupturable seal, so that the tie cannot be released without breaking or rupturing the seal. It consists in the elements and features of construction shown and described, as indicated in the claims.

In the drawings Figure l is a side elevation of a bag having a tie provided with the locking and sealing device embodying this invention. y

Fig. 2 is top plan view of the tie securing and sealing device with the cords or tie therein and secured at sealed position.

Fig. 3 is a section at the line, 3-3, on Fig. 2.

Fig. 4 is a section at the line, 4&4, on Fig. 3.

Fig. 5 is a perspective view of the cordclamping, seal-holding device with its several parts separated.

Fig. 6 is a section at the line` 6*(5. on Fig. 3.

In the drawings, A represents the bag to be tied, B the cord or tie which secures it. by constricting it at the mouth in the usual manner; C is the base member of the tie-securing device. This member comprises three pieces, the main plate l, which is designed to be stamped from a metal sheet or thin plate having longitudinal flanges, i, for stiffening it, having at one end an upturned lip or flange, 1b, turned longitudinally outward for a. short extent at le, to form a shoulder for lodgment of the latch as hereinafter explained, then turned upward at 1d. to furnish a guard for the end of the latch, lthen folded back over the shoulder or seat, l, for retaining the latch as hereinafter explained, the final lip, 1, having struck down from it at one end a short lug, lf, to furnish a stop for the swinging movement of the latch to sealing position. The lip or flange, 1b, has two cord apertures. 1g, through which the .cord may extend under the seat or shoulder, 1c. At the other Specification of Letters atent.

end of the base plate, l, there is mounted a second piece, 2, of the base member which is a U-shaped part having two upstanding fianges, 2a, 2, provided with two cord apertures, 2b, alined with the corresponding cord apertures, 1g. This piece, 2, is secured to the main piece, 1, by being lodged between the longitudinal flanges, l, la, which are clenched down onto the lateral edges of the neck of the U member, as seen at` lh. The third piece of the base member, C, is a label or tag` holder, 3, being a thin metal plate having a. rectangular aperture, 3, and longitudinal irl-turned lips, 3b, forming flanges which may meet substantially at the longitudinal middle line, rendering said part, S, substantially tubular, and affording means for securing said tubular member upon the haelt or under s'de of the part, l, by any convenient means, as soldering or spot-welding.

5 is a cord-clamping saddle which is a piece of metal plate folded to form parallel iianges, 5a, spaced apart so that the saddle enters and fits loosely between the two parallel flanges, 2, 2, of the part, 2, said flanges, 5d, having cord-striding notches, 5b, positioned for alinement with the cord apertures, 2b, of the part, 2, when the saddle is entered between said flanges, 2. A stud, 6, rigid with the base plate, 1, positioned centrally in the rectangular space defined by the flanges, 2, 2a, of the piece, 2, serves to position the cord clamp, 5, the latter having a central aperture for engaging said stud.

7 is a latch member pivoted upon the stud, 6, lunder the head thereof, and thereby held into close relation with the upper edges of the flanges, 2a, 2a. in the swinging movemont which the said latch may have about said pivot stud. The cord clamping saddle member. 5, has two upwardly projecting bosses, 5c, 5c, and the latch member, 7, has two recesses, 7, 7, said bosses and said recesses being at diametrically-opposite positions in the respective parts with respect to the pivot stud or axis of the latch, and said bosses and recesses coperate in a cam action for clamping the saddle onto the cord eX- tending between the two flanges, 2, 2, of the piece` 2. The latch member, 7. is of such length from its pivot on the stud, 6, that its remote end enters closely behind the guard fiange, ld, and under the retaining iiange or lip. le, and is stopped against the lug, lf. Said latch has longitudinal flanges,

, folded up and over toward each other to meta-l which may be inserted longitudinally therethrough; and at the stopped 4position of the latch against the lug, lf, said tube or sleeve registers with a seal aperture, lj, of the guard flange, ld. At this position ofthe latch the cam projections, 5C, of the clamping saddle, 5, have been crowded out of the recesses, 7, by the rotation of the latch, and the saddle has been clamped down tightly upon the cord, B, engaged in its cord-striding notches.

Any form of seal consisting of a strip which can be inserted through the seal tube or sleeve, 7a, and the seal aperture, lj, and provided with means or features of construe# rtion which prevent it `from being withdrawn or pulled on through, may be employed to securethe latch at cord-striding position so that it cannot be released to release without rupturing the seal.

In the drawings there are shown two lfamiliar forms of seals which may be employed in this device, the first being a familiar type consisting of a thin strip or tape, F, having at ,one end a sealing bulb, F1, through which the free end of the strip is inserted after it has been passed through thesleeve andy seal aperture. -This .forni of seal .is familiar and needs no specific descrip* tion of itsown construction. In F ig. 2 there is shown another form of seal consisting of a strip of metal G, adapted to be inserted through the sleeve andseal aperture, having at one end a cross-head, G1, which; may be drawn up closelyl'against theouter side of` thelguard, ld, the other -end portionlof the strip ,which proj ects beyond ,the sleeve being weakened by scoring or Vaperturesat a transverselinc which stands at the inner end of the seal tube or sleeve when the cross-head cithis seal is against the guard, 1d, the method of sealing being to fold back the protruding end portion of the seal onto vthe seal tube or sleeve, the inetalof` the seal being such that it cannot -be unfolded vwithout breaking atthe scoredor weakened crossl line. This form of seal isfalso familiar and the seal in either form constitutes no part of the. present invention.

lVhen the form of seal last described is to` I i be employed, Ait will be found vdesirable toA provide a slip ring, 10, on the seal sleeve or tube, which can be slipped over the reversed end of the seal to` prevent the latter from becoming accidentally engaged, and thereby folded back or broken.` When this slip sleeve is employed, it is retained on the seal sleeve or tube by` a. slight boss, lm, lug struck down from the back side of the tube, as seen at 7g, the slip sleeve being adapted to spring over this boss when entered upon the sleeve at the open end and the slip sleeve has an aperV the cord' ture, 10a, which snaps into engagement with the boss for positioning the slip sleeve at the proper position along the length of the seal tube or sleeve for masking the end of' the refleXed seal and preventing it from being` accidentally engaged. AThen the properly authorized person desires to release the tie, the slip sleeve willbe readily pulled back from off1 the end of the seal and the latter can then be refleXed for breaking it.

. For securing a tag or label which may be inserted in the tag slide-way, against accidental or intentional removal so long as the tie is locked,.the base has an aperture, c3, and a clamping saddle, 5, Vprovided with a lug or finger, 5d, extending in said aperture and long enough to extend. across the open end of the tag or label-holding space in the tag holder, 3, when the said clamping saddle is forced into cordgripping position by the closing of the latch. Y

When the cord tobe gripped by the clamping jaw isl very hard. or glazed, as is sometimes the case with new cord, slipping is not impossible, notwithstanding the grip of the cordclamp upon it, so that it may be possible without tearing it to draw it through the jaws sufliciently to release the tie. To provide against this possibility there may be provided an additional gripping device, having a more positive engagement with the cord, and one which if operative at every instance ofclamping, would deteriorate the cord, but which will be unobjectionabie if it only comes into operation when an attempt is made to force the cord through the clamping jaw. Such a device is shown at 8,'

consisting of aV Ushaped vmember having V8a, of theY part, 8, are yof such height or width that the serrated edgesproject into the straight-linepathV of' the cord. when stretched taut from the gripping edges of the flanges, throughthe cord apertures of flanges, 2n. From'. this vrelation of' the parts it results that when stress is applied to the cords in an attempt to pull them through the gripping device, they'are thereby drawn onto the serrated edge of the part, 8,'and grippedpositively by said serrations, so that said cord cannot be Vpulled through without tearing it by the serrations. l

l. In combination with a cord runway, a clamping jaw carried by the base opposite the cord runway; a latch adapted at one position to be lockedto the izo base having the base, having a cam for clamping the jaw onto the cord in the runway by the swinging of the latch to locking position, the base and the latch having seal-accommodating pass-.

ages which are registered at cord-clamping position, and a seal which is introducible into said passages transversely of' the cordreleasing movement of the latch, and means defeating the withdrawal of the seal unruptured.

2. In the structure defined in claim l, foregoing, the latch being pivoted for swinging in the plane of the seat of the seal therein, the base having a guard behind which the free end of the seal seat of the latch swings for clamping the cord, said guard having a seal passage which registers with the seal passage of the latch; whereby the seal is opposed edgewise of the cord-releasing movement o the latch.

3. In combination with a base and means for seating and clamping the cord therein, said means comprising a rotatable camcarrying member, said member having a seal-holding tube or sleeve open at both ends, the base having a guard projection behind which one end of the seal tube stands at cord-clamping position, said guard having a seal aperture registered at said position with the seal tube.

4. In combination with a base having a plurality of spaced-apart 11p-standing lips or .lianges provided with cord apertures; a

clamping saddle having fianges spaced to fit loosely between two consecutive flanges or limbs of the base, and having cord-striding notches positioned for registering with the cord apertures oi said flanges; a latch device pivoted between the said two flanges of' the base for swinging in a plane transverse to the direction of' rojection of said fianges, the clamping saddle being apertured for mounting on said pivot and for moving there-along 1n its clamping action, and cooperating cam depressions and projections in the saddle and the latch for clamping the cord in the swinging movement of the latch.

5. In combination with the structure defined in claim 4 foregoing, a slide on the seal-seating sleeve, adapted to mask a reverse seal end, and means for yieldingly engaging it with the sleeve at seal-masking position.

6. In the construction defined in claim. 4, foregoing, a serrated member for engaging the cord, positioned between the clamp and the flange which has the cord aperture, with itsV serrated edge projecting into the straightline path of the cord when stretched taut from the cord aperture to the saddle notch.

7. In the construction defined in claim 4, foregoing, a U-shaped member lodged on the latch ivot under the saddle and having its U-limb or flange projecting between the saddle limbs respectively and the adjacent flanges of the base, said U-lirnbs or flanges being serrated and protruding into the straight-line path of the cord when stretched taut from the cord apertures to the saddle notches respectively.

8. In combination with a base having a cord run-way, a clamping jaw carried by the base opposite the cord run-way; a latch adapted at one position to be locked to the base, and having means for clamping the jaw onto the cord runway by its movement to that position; the base having at the opposite side from that at which the clamping jaw is situated a tag-receiving slide-way whose end open for entering the tag thereinto is substantially even with the end ot' the base at which the clamping jaw is situated, said clamping jaw having a projection which is thrust across said opening to bar the escape of' the tag by the cordclamping movement of said clamping jaw.

In testimony whereof, I have hereunto set my hand at Chicago, Illinois, this 3rd day of January, 1921.
