uttern sprinkler.

The invention relates to a nut sprinkler in the form of a pair of scissors, especially for breaking loose nuts on stud bolt connections. These scissors have two scissor arms that are moved hydraulically *.

Is are hydraulically operated shears for cutting known from reinforcement bars, where at the end of each of the two arms a hydraulic cylinder each causes the movements · The arms are just behind the two cutting edges rotatably mounted in a pair of tabs by means of bolts · These seers are due to the Both arms adjoining Druekschläuehe unwieldy and also expensive to manufacture. It is further known to firmly attach a hydraulic cylinder to an arm, the piston rod of which when it extends pushes the free arm away.

The invention has set itself the task of a Nut sprinkler in scissor shape, which is extremely handy, is robust and space-saving to create.

To this end, according to the invention is to be actuated of the nut sprinkler, a hydraulic cylinder installed perpendicular to the cutting plane in one movement

The extension of the piston rod of the hydraulic cylinder is provided with a wedge, that glides back and forth between two jaws pivotably connected to the scissor arms and so on the latter spreads · Me jaws are guided between shields in which the axes of rotation of the scissor arms are supported are · The front ends of the scissor arms are to be sleeves in which the cutter bearings are inserted · The cutter carriers are interchangeable in the Sleeves attached. The flanks of the cutting edges show a concave course »

An exemplary embodiment of the invention is shown in the drawing. Show it
Fig. 1 is a side view of the new nut sprinkler

in scissors shape,
Fig. 2 is a top plan view of Fig. 1, partly in

Cut,
Fig. 3 is a front view according to Fig. 1, in which the front shield has been omitted,

Fig. 4 a cross section along line IV-IV of Fig. 3 * Fig. 5 a cross section along line VV of Fig. 3 »

In the figures, 1 denotes the handle on which the shields 2 and 3 are perpendicular to the longitudinal axis of the handle are attached. Jaws 4 · and 5 are guided between these shields 2 and 3 · These jaws are via round bolts 6 and 7 pivotably connected to the scissor arms 8 and 9. Moving between the jaws 4 and 5 see a piece 10, which is in extension of the piston rod 11 with a dowel pin 12 is connected to the latter. When the wedge is advanced, the jaws 4 and 5 are spread apart, they take by means of the round bolts 6 and 7 Scissor arms 8 and 9 with. The latter are in the shields 2 and 3 via round bolts 13 and 14, their removal is fixed, deehbar stored, so that the short front ends by spreading the inner scissor arm ends the arms that carry the tendons come closer to one another will. The front ends of the scissor arms 8 and 9

end in sleeves 15 and 16 in which the cutter carriers 17 and 18 are interchangeably inserted «. Goal in part As Fig. 4 shows, the cutter carriers have an oval cross-section. The planks of hers Cutting edge 19 are concave except $ which is special has a favorable effect on the blasting process »
