SEALING MEANS OF DUCTILE MATERIAL Filed June 28, 1950 INVENTOR. en! I77OOAE/W9HR5 W, mo PM United States Patent SEALING MEANS OF DUCTILE MATERIAL Jan Moolenaars, Velp, Netherlands Application June 28, 1950, Serial No. 170,812 Claims priority, application Netherlands June 30, 1949 Claims. (Cl. 292-310) This invention relates to sealing means for marking, closing or identifying purposes of the type comprising a rollable tongue provided with upwardly bent teeth at its side edges and an accommodation for the rolled-up tongue located at the base of said tongue, and to a pair of tongs for rolling-up said tongue. In actual practice it has been found that the tongue wrapped around tying means, such as a cord, by means of a pair of tongs adapted for this purpose, may be removed from said tying means and be re-arranged about same in various manners without these manipulations leaving any visible traces. Furthermore, it has been found that during the normal use of the sealing means the tag becomes sometimes torn off the rolled-up tongue owing to various fortuitous circumstances.

In order to entirely prevent such tampering with the tongue, the tongue of the sealing means according to the invention is split up into a main tongue and an auxiliary tongue, the latter being enclosed by the former, the feet of the main and the auxiliary tongues preferably being in alignment with each other. According to the invention the auxiliary tongue may be provided with at least one lip directed towards the side edge of the main tongue and cut out of the material of the latter.

In sealing means of the aforementioned type the accommodation for the rolled-up tongue may furthermore be provided according to the invention with two teeth or lips located at or near the ends of the accommodation, which teeeth or lips have their points bent towards each other and which are preferably provided with one or a plurality of marginal notches in such a manner that the teeth of the tongue will stick in said notches.

According to the invention the tongs for rolling up the tongue may have the characteristic that the radius of the face for rolling up the auxiliary tongue is smaller than the radius of the face for rolling up the main tongue.

In illustration of the invention an embodiment of the sealing means and of the tongs for applying said means will be described with reference to the accompanying drawing.

Fig. 1 is a view in perspective of the sealing means;

Fig. 2 is a plan view of the sealing means with the tongue in rolled-up condition;

Fig. 3 is a section on the line Ill-III in Fig. 2;

Fig.4 is a side elevation of the tongs;

Fig. 5 is a plan view in part of the portion of the tongs embodying the faces for rolling up the tongues;

Fig. 6 is a side view in part of the portion of the tongs embodying the faces for rolling up the tongues; and

Fig. 7 is a partial front view of the portion of the tongs embodying the faces for rolling up the tongues.

As appears from Fig. 1, the sealing means comprises a main tongue 1 enclosing an auxiliary tongue 2 in such a manner that the bases of the main and the auxiliary tongues are in alignment with each other and merge into an accommodation 3 for the rolled-up tongues, to which accommodation 3 the tag 4 is connected.

The side edges of the main tongue 1 are provided with upwardly bent teeth 5.

The auxiliary tongue 2 may be entirely cut loose along the top and the side edges, but it is also possible to groove the material along the top and the side edges of the auxiliary tongue so deep that when the tongues are rolled up they are separated from each other.

For wrapping the tongues 1 and 2 around tying means 6 in order to bring the sealing means in the condition 2,701,159 Patented Feb. 1, 1955 ice an immovable limb 19 of the tongs, while the tongues 1 and 2 will rest on supporting member 8. At the side facing the limb 19 head 9 of the supporting member 8 is provided with semi-cylindrical faces 10 and 11 for rolling up the tongues. The radius of the faces 10 is larger than that of the face 11.

By means of a toggle joint lever 13 pivotable at pivot 12 which at 14 acts on the supporting member 8, said supporting member 8 may be moved towards the limb 19 of the tongs. During the initial stage of this movement only the top 7 (Fig. 1) of the main tongue is wrapped around the tying means 6 (Fig. 2) by the face 11, whereupon during the continuing displacement of the supporting member 8 the main tongue 1 will be further rolled up by the faces 10 while the auxiliary tongue 2 is simultaneously rolled up by the face 11, the rolled-up auxiliary tongue 2 having a smaller diameter than the rolled-up main tongue 1.

When the tongues 1 and 2 are in their final rolled-up condition as shown in Fig. 2, the inner edges of the main tongue 1 will overlap the edges of the auxiliary tongue 2 which has been rolled up to a smaller diameter. It is not possible, therefore, in any attempt to fraudulently remove the sealing means from the tying means first to roll back the auxiliary tongue 2. If an attempt is made to roll back the main tongue 1, this tongue, owing to the auxiliary tongue having been punched out of it, has been greatly weakened and will break off as a rule. This breaking off may be promoted by providing the auxiliary tongue 2 with a lip 15 (Fig. 1) punched out of the material of the main tongue, whereby an extra weakened Zone is formed in the main tongue 1.

The accommodation 3 is provided at both ends with a tooth or lip 16 and 17 respectively. To the left in Fig. l the tooth 16 is punched out of the material of the accommodation while on the right hand side in Fig. 1 the tooth 17 at the end of the accommodation is bent upwardly.

The position of the teeth 16, 17 relative to each other is such that the distance between their base is larger than between their points. When the tongue 2 is now wrapped about tying means 6, the teeth 16, 17 will ultimately come to rest within the tubularly rolled-up tongue 2, as schematically shown in Fig. 2. The teeth 16, 17 which have largely been taken up within the tubularly rolled-up tongue and which have penetrated into the tying means 6 will obturate the ends of the accommodation 3. When the teeth 16, 17 are in this position they cannot be bent back if any attempt is made to remove the tying means 6 from the rolled-up tongue and to reinsert it therein without leaving visible traces.

The teeth 16, 17 are provided with one or more notches such as 18 in tooth 17 and 20 in tooth 16 in Fig. 1 so that the teeth 5 of the tongue will become stuck in said notches during the rolling-up of said tongue.

In attempts to fraudulently remove the sealing means from the tying means in other ways, insurmountable difficulties are encountered owing to the fact that the centre lines of the rolled-up main and auxiliary tongues do not coincide. In addition the top of the auxiliary tongue will be deflected by the adjacent edge of the main tongue during the rolling-up of said tongues and as a result this top will penetrate into the tying means. The various features of the sealing means described above render it practically impossible to remove the sealing means from and to rearrange it about the tying means without leaving visible traces.

I claim:

1. A sealing means of ductile material comprising a rollable tongue having upwardly bent teeth at its side edges and an accommodation for the rolled-up tongue located at the base of said tongue, said tongue being divided into a main tongue and an auxiliary tongue, said auxiliary tongue being partly surrounded by said main tongue, the bases of the main and the auxiliary tongues being in alignment with each other.

2. A sealing means as claimed in claim 1, and wherein the top of the auxiliary tongue has thereon at least one lip directed to the side edge of the main tongue and cut out of the material of the latter.

3. A sealing means of ductile material as claimed in claim 2, said accommodation having two teeth at the ends thereof, said last named teeth having their points bent towards each other.

4. A sealing means as claimed in claim 3, said last named teeth having a marginal notch therein.

5. A sealing means of ductile material as claimed in claim 1, said accommodation having two teeth at the 10 ends thereof, said last named teeth having their points bent towards each other.
