^{ΡΑΤΕΝΤΑΜΤ} ·

The one shown in the drawing by FIG. 1 in a front view and FIG. 2 in a plan view Embodiment of the switching device protected by patent no. 83732 is intended for such purposes as reversing require at any point of the piston barrel, while at the. by the Main patent marked type a reversal only after completion of the piston stroke is possible.

Guided in a suitable manner in the box m rack ^ c is attached to the piston rod by means of the arms "'^ M. On the bracket m , the slide u with the catches s and s ^{1 is} guided by the screws η and n ¹ , which also serve as releasers, and is cranked flat on the bracket carrying the wire spools and goes into guide slots. The slide has a cutout ν respectively over the two armatures. v ¹ , one wall of which is bevelled in such a way that it touches the thumb / or. I ¹ of the lever arms bearing the weights ρ and p ¹ gradually step onto the surface of the armature in question, respectively. stands out from the same.

The contact spring d , which opens the circuit after the reversal has occurred, is also attached to the slide u , and has here 0 o between the contact surfaces insulated on a bracket ^. , gg ^{1 to} cover only the path that corresponds to a tooth gap. When actuating the device, the rack ^ takes respectively through the driver s. s ^! the slide. «by the length of the tooth division in the direction of movement with; then the driver is respectively by the pins η. n ^l excavated. As a result of the changed position of the slide, the contact spring d is moved over the glass plate f onto the contact plate pair mediating the opposite control and the corresponding thumb / bezw. I ^{1 of} the weights ρ and p ^1, which have taken the place of the running weights, through the cutouts respectively. v ¹ stepped onto the surface of the magnet armature that has just been drawn in. In this way, all conditions are met which cause the immediate reversal of the current connection established by the relevant switch (thermometer, manometer, etc.).

Claims (1)

Patent claim: An embodiment of protected by patent no. 83732 Changeover 'for valves, dampers, valves, gate valves and the like., Characterized by a rack (^) to ■ the piston rod, and by a slider (u) with two bethätigten of the rack carriers fs and S ¹ J and excerpts (v and V ¹ J for the thumbs (I and I ¹ ) of the lever weights (p unap ¹ ) used to relieve the armature to enable the piston to be reversed at any point in the piston stroke. 1 sheet of drawings.
