v. 28. £. & 8Pa t entamt Müachen SiRn.-Hammer * - "

The innovation concerns a device to be operated by compressed air for marking materials with different Strengths like iron and steel - light and heavy metal and the like

As the marking of different materials in smelting works and rolling mills, but also in many other branches of industry {is done by handshake numbers depends on the practical ■■ Usability of such a device largely depends on the total weight, the ability to regulate the impact force, the execution of single strikes, the faster replacement of the number of strikes « or number wheels with the least amount of air

The task is, with sufficient impact force and execution of single blows of the device at the lowest Air consumption, the total weight of which is to be reduced so far, that it becomes a hand tool, so it can be easily operated and handled by a single person. The clout with To regulate single strokes so that it is different for materials Degrees of hardness can be used in the warm or cold state.

The innovation shows a simple way how to use such a device with the lowest weight and simplest operation, with adjustable impact force and single impacts with minimal air consumption. It essentially consists of that the hollow polypropylene eaten from a light metal alloy A wear bushing made of high-quality, wear-resistant material for the firing pin, concentric to its central axis contains unc in connection with αem exhaust duct a uniform Piece forms.

In order to save energy as well as for aie flanges una aas venti.1 what light metal used. next to it is ncch. The further innovation Maänamae fcjrforosrlicii, is to use an uncomplicated and light holder for recording the punch numbers and to use holding fibers for the bculagoolzen. lock.

liie described fiaerücmale of the .novation surrendered together, c-as light hand tool for marking steel and the like, with a total weight of 4 to max i? kg.

Examples of firing are illustrated in the attached drawing rings, show it:

Figure 1 shows an embodiment in which the guide tube with the wear sleeve and the exhaust duct, in one piece are made from a special profile and the firing pin is brought back using compressed air. The holder for recording of number wheels, the retaining springs and the flat slide reversing valve for executing single blows as well as the throttle screw for setting the impact force.

Figure 2 shows a simplified example in which the wear sleeve is only enclosed by the guide tube and the The return spring returns the firing pin to its original position is brought. The bracket for recording the beat numbers, a single-acting valve and the exhaust collar for regulation the clout,
