Device for measuring tooth edges, especially of postage stamps

The invention relates to a device for measuring perforation edges, in particular of postage stamps.

Postage stamps can have different perforations that differ from one another in terms of tooth shape and, above all, tooth pitch. These perforation differences can be of great importance for the value of older postage stamps. The devices known to date for determining different perforations on postage stamps are designed as so-called "perforation keys", in which different perforation images are printed on cardboard, metal or a foil. Using these perforation keys to correctly determine the perforation of a stamp placed on the perforation key requires a certain amount of skill and, above all, a very good eye.

The invention is based on the object of designing a device of the type mentioned at the outset in such a way that the determination of a toothing edge is facilitated in comparison with several toothing patterns.

The stated object is achieved according to the invention in that the device has at least one tooth carrier that is adjustable relative to at least one contact area for tooth edge objects, on the edge of which several tooth combs with different tooth pitches are formed at a distance from one another.

In the device according to the invention, the various tooth patterns are designed as spatial structures in the form of tooth combs, which can be inserted into the toothed edge of a stamp or the like and thus make it much easier to correctly determine the toothing. This is particularly helpful in difficult situations. Quarter teeth, half teeth or three-

The device can be designed in different ways and, for example, have a strip-like, longitudinally adjustable tooth carrier. The tooth carrier can be a disc that is rotatably mounted on a holder, on the edge of which the tooth combs are separated from one another by edge cuts. For example, the holder can consist of a plate that has a disc-shaped, rotatable tooth carrier on both sides. In any case, the tooth combs can have a length that corresponds to the average

Width of a postage stamp and thus in most cases allows a tooth measurement over the entire perforation edge of a postage stamp*

Advantageously, the holder on which the at least one toothed carrier is adjustably mounted can be provided with at least one support surface for stamps or other objects with a toothed edge as well as with an edge or window area in which the edge of the toothed carrier provided with the tooth combs is exposed, so that a toothing measurement can be carried out both on stamps that can be placed on top and on stamps stuck onto letters, cards or the like using the device. The toothing measurement can be made easier if the tooth combs of the toothed carrier and the support surface of the holder have a different and contrasting color.

An embodiment of a device designed according to the invention is explained in more detail below with reference to the accompanying drawing.

In detail:

Fig. 1 is a plan view of the device;

Fig. 2 is a cross-section through the device along the line II-II in Fig. 1.

The device has a plate-shaped device body and holder 20, on both sides of which a circular disk-shaped tooth carrier 21 and 22 is freely

rotatably mounted* The holder 20 is made of one piece; made of plastic and is provided in its center with spring-loaded retaining tongues 23 for supporting the two disc-shaped tooth carriers 21 and 22. The outer edge of the holder is connected to protective webs 24 on both sides, which protect the outer edges of the tooth carriers 21 and 22

The slat-shaped holder 20 is guided into the area of an attachment part 20.1 of the plate-shaped holder 20, which forms a support surface for stamps 25 on both sides. At a point opposite the support surfaces for the stamps 25, the slat-shaped holder 20 is provided with an edge cut 26 which also interrupts the protective point 26 and in which the edge area of the toothed carriers 21 and 22 is exposed.

The two tooth carriers 21 and 22 are provided over their circumference with several tooth combs 28 separated from one another by edge cuts 27, which differ from one another by a different tooth pitch. The tooth combs have a length sufficient for an exact comparison with the perforation edge of a postage stamp. The disk-shaped tooth carriers, also made of plastic, have a lower thickness in the area of the tooth combs 28, and the plastic tooth combs can be easily inserted into the perforation edge of a postage stamp.

The tooth combs can be moved by turning the tooth carriers 21 or 22, which is facilitated by grip recesses 29 formed in the tooth carriers, either into the holder attachment area 20.1 forming the support surface, where the

Protective webs 24 end at points 30 and 31, or in the area of the opposite holder cutout 26, where the toothing measurements take place. The holder is colored with a dark color, in particular blue, at least in the area of the support surfaces for the stamps 25, while the tooth combs have a lighter color, preferably gray, and thus provide good contrast. The tooth pitch is indicated on each tooth comb as the number of teeth per unit length . In the embodiment shown, for example, each tooth carrier 21 and 22 has fourteen individual tooth combs with different tooth pitches.
