Abstract
Abstract A Foucault-current linear-inductor suspension assembly on a railway vehicle comprises an inductor movable between upper and lower inoperative and operative positions in a vertical plane through the rail and fixed to a beam located in a vertical plane passing through the bogie axle boxes, the beam being coupled to the bogie frame by pins fast therewith and links connecting the pins to the bogie frame and guided in its movement with the inductor by guides in the bogie axle boxes.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
114 words
A suspension for a Foucault-current linear-inductor on a railway vehicle bogie having axle boxes and a frame comprising a Foucault-current linear inductor, means for the transmission of forces from said inductor to the bogie frame and means for displacing said inductor in a vertical plane passing through an adjacent rail between an upper inoperative position and a lower operative position, a beam supporting said inductor located in a vertical plane substantially passing through the bogie axle boxes, arm means connected to said beam, link means connecting said arm means to the bogie frame and guide means in the axle boxes for centering and supporting said beam in the lower operative position of said inductor.
Claim 2
Dependent Claim
114 words
A suspension for a Foucault-current linear-inductor on a railway vehicle bogie having axle boxes and a frame comprising a Foucault-current linear inductor, means for the transmission of forces from said inductor to the bogie frame and means for displacing said inductor in a vertical plane passing through an adjacent rail between an upper inoperative position and a lower operative position, a beam supporting said inductor located in a vertical plane substantially passing through the bogie axle boxes, arm means connected to said beam, link means connecting said arm means to the bogie frame and guide means in the axle boxes for centering and supporting said beam in the lower operative position of said inductor.
Claim 3
Dependent Claim
18 words
A suspension as claimed in claim 1, said guide means including replaceable wedge means for supporting said beam.
Claim 4
Dependent Claim
14 words
A suspension as claimed in claim 1, said inductor and said beam being integral.
Claim 5
Dependent Claim
28 words
