Claims (1)

PATENT-ANSPRÜCHE : 1. Einrichtung zur Konstanthaltung der Belastung elektrisch angetriebener Holzschleifapparate, dadurch gekennzeichnet, dass bei Entlastung eines oder mehrerer Stempel der Druck der anderen Stempel selbsttätig in Abhängigkeit von der Stromstärke der antreibenden Elektromotoren erhöht wird, zum Zwecke, den Gesamtenergieverbraueh ohne Verlust konstant zu erhalten. PATENT CLAIMS: 1. Device for keeping the load on electrically driven wood grinders constant, characterized in that when one or more stamps are relieved, the pressure of the other stamps is automatically increased depending on the amperage of the driving electric motors, for the purpose of keeping the total energy consumption constant without loss. 2. Ausführungsform der Einrichtung nach Anspruch 1, gekennzeichnet durch einen von einem Serientränsformator (P S) im Stromkreis des Hauptmotors (A) gespeisten, die Ventile oder Steuerorgane für die Belastungsänderung betätigenden Hilfsmotor (H), dem bei normaler Belastung ein Gewicht (Q) Gleichgewicht hält, wobei die Einrichtung so getroffen ist, dass bei steigender bzw. fallender Belastung des Hauptmotors der Ililfsmotor die Ventile so verstellt, dass die Gesamtbelastung die gleiche bleibt. 2. Embodiment of the device according to claim 1, characterized by one of a series transfer transformer (PS) in the circuit of the main motor (A) fed, the valves or control elements for the load change actuating auxiliary motor (H), which under normal load a weight (Q) balance holds, the device being designed so that when the load on the main engine rises or falls, the auxiliary engine adjusts the valves so that the total load remains the same. 3. Ausführungsform der Einrichtung nach Anspruch 1, dadurch gekennzeichnet, dass der Hilfsmotor (IT) an entsprechende Punkte der Statorwicklung des Antriebsmotors (A) EMI2.1 4. Ausführungsform der Einrichtung nach Anspruch 1, dadurch gekennzeichnet, dass die Zugkraft eines in den Stromkreis des Antriebsmotors (A) geschalteten Solenoides (M) die Ventile oder Steuerorgane für die Belastungsänderung beeinflusst. 3. Embodiment of the device according to claim 1, characterized in that the auxiliary motor (IT) is connected to corresponding points on the stator winding of the drive motor (A) EMI2.1 4. Embodiment of the device according to claim 1, characterized in that the tensile force of a solenoid (M) connected to the circuit of the drive motor (A) influences the valves or control elements for the change in load. 5. Ausführungsform der Einrichtung nach Anspruch 1, dadurch gekennzeichnet, dass EMI2.2 5. embodiment of the device according to claim 1, characterized in that EMI2.2
