Device for dampening the relative movement of a first structural member in relation to a second structural member

The invention is a damper and a method for protecting buildings and similar structural systems from dynamic loading such as loading caused by earthquakes, strong winds or machine vibrations. More specifically, the damper is made from structural members being interconnected in frictional or visco-elastically dampened rotational joints. Due to the dampening of the joints, relative movement between the structural elements is dampened. In particular, the damper is useful for base isolation, e.g. in order to allow a building or a machine to move in a dampened movement relative to its foundation or in order to allow a cable stay of a cable stay bridge to move in a dampened movement relative its fixation point on the bridge.

The invention relates to a device for damping vibrations in a drive train (21, 22, 23, 1, 24, 25, 28), in particular for plug screws (27) in the pulp and paper industries. The device is principally characterized in that a cylindrical shaft (2), preferably designed as a hollow shaft, is provided, wherein said cylindrical shaft is arranged between the halves of a coupling and at least one ring (8, 11, 11', 11'') having friction surfaces (12, 12') is arranged around said cylindrical shaft.

237,227. Compagnie d'Applications MÚcaniques. July 17, 1924, [Convention date]. Vibration-dampers having outside and inside shells with interposed friction elements are provided with similarly-shaped additional external shells and corresponding friction elements which in action may lag behind the original elements. The ordinary outside shells 3, 4, Fig. 1, and inside shells 1, 2 are separated by friction elements 5 and are formed with arms A, B. The additional external shells 20, 20<a> are separated from the shells 3, 4 by additional friction elements 21, 21a, and are provided with arms 22, 22<a>, which may be connected to the arm A by means allowing limited or spring-controlled movement, so that the additional friction elements do not come into action until some movement has already taken place. The inner elements 1, 2 are pressed apart by a helical spring. The Specification as open to inspection under Sect. 91 (3) (a) comprise also in connection with the ball 7, Fig. 5 (Cancelled), and nut 10 the provision of spherical or like surfaces bearing on washers 8<c>, 11<c> which are recessed at 8<d>. The holes in the shells are also larger than the bolts so that relative movement in various directions of the two arms may take place. This subjectmatter does not appear in the Specification as accepted.

Disclosed is a vibration damping apparatus incorporated in the crossing of diagonal members such as braces of a framed structure for damping vibration imparted by external force such as an earthquake or a strong wind. The apparatus comprises a plurality of rotatable members or discs, a resistive body disposed between the discs, and a pair or pairs of link bars causing relative rotation of the discs in response to the impartation of the external force, whereby the vibration is damped by the resistance force of the resistive body resisting to the external force.

245,806. Gabriel Snubber Manufacturing Co., (Assignees of Foster, C. H.). Jan. 12, 1925, [Convention date]. Vibration-dampers. - In a vehicle recoil-preventing apparatus in which a strap is wrapped several times around two relatively movable members with a compression spring between them, means are provided for taking in the slack of the strap during downward movement of the vehicle frame before the compression spring operates, during downward movement and an additional strap encircling the relatively movable members and secured to one of them is also provided. The strap D, Figs. 1 and 3, is connected at one end to the axle 3 and is wrapped several times around a member A fixed to the frame 1 and a member C slidable towards and away from the member A. A spring 11 tends to separate these members in opposition to the strap D. A steel strip F of less curvature than the outer convolution of the strap is attached thereto by rivets 17 and serves to take up the slack of the strap when the frame 1 approaches the axle 3, as shown in Fig. 3, and also reduces the friction between the different turns and so assists the separation of the members A, C. The inner end of the strap D is secured by rivets 13 to a strip of metal 12, preferably brass, interposed between several of the inner turns of the strap. The end of this strip 12 is hooked to engage the end of the fixed member A and is also connected by rivets E' to an additional strap E which extends round both the fixed and the movable members A, C. Specification 1587/12 is referred to.
