Abstract

587,588. Vibrationdamping devices. AKT.-GES. BROWN, BOVERI, & CIE. Sept. 13, 1944, No. 17520. Convention date, Oct. 5, 1943. [Classes 110 (i) and 110 (iii)] In a vibration-damping device for the blades of turbines, blowers, &c., comprising a wire 1 which fits loosely in holes 2 in the blades 3 and is pressed into frictional contact with the edge of each hole by centrifugal force, the wire consists of two half-round parts, the plane sides in contact of which are perpendicular to the direction of the centrifugal force. The individual parts may be open-ended, and their cutting, points are preferably displaced. The Specification as open to inspection under Sect. 91, comprises also the use of a circular wire consisting of three separate sectorial parts, or of a number of separate circular wires which may be twisted together. The individual wires may be of resilient material and bent in such a manner that they fit snugly in the holes and are supported against one another at points 22 between the holes, as shown in Fig. 7 (Cancelled). This subjectmatter does not appear in the Specification as accepted.
