Abstract
Abstract An electromagnetic brake is disclosed in which the connection between adjacent padlike braking members is obtained with a particular kind of hinged connection. More particularly, a semicylindrical projection of a pad cooperates with a corresponding hollow formed in the adjoining padlike member. The component parts are so arranged that the replacement of a padlike member is accompanied by the replacement of the hinged connection also.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
144 words
An electromagnetic brake for track mounted vehicles, comprising an elongate electromagnetic brake energizing coil, a plurality of padlike braking members mounted in a row on said coil to extend longitudinally thereof, and having thereon active braking surfaces disposed beneath said coil frictionally to engage a rail surface when said coil is energized, means for rigidly fixing the two members at opposite ends of said row to said coil, means mounting the remaining members in said row between said two members for limited movement relative to said coil, each of said members including a removable wearing pad having thereon one of said braking surfaces, said mounting means including means hingedly connecting the confronting ends of adjacent members in said row to allow pivotal movement of said remaining members about axes disposed to extend through said wearing pads below said coil and above said braking surfaces.
Claim 2
Dependent Claim
144 words
An electromagnetic brake for track mounted vehicles, comprising an elongate electromagnetic brake energizing coil, a plurality of padlike braking members mounted in a row on said coil to extend longitudinally thereof, and having thereon active braking surfaces disposed beneath said coil frictionally to engage a rail surface when said coil is energized, means for rigidly fixing the two members at opposite ends of said row to said coil, means mounting the remaining members in said row between said two members for limited movement relative to said coil, each of said members including a removable wearing pad having thereon one of said braking surfaces, said mounting means including means hingedly connecting the confronting ends of adjacent members in said row to allow pivotal movement of said remaining members about axes disposed to extend through said wearing pads below said coil and above said braking surfaces.
Claim 3
Dependent Claim
51 words
An electromagnetic brake as defined in claim 1, wherein said connecting means comprises a semi-cylindrical projection on one end of each of said wearing pads, and a correspondingly shaped semi-cylindrical recess formed in the confronting end of the adjacent wearing pad to receive said projection, said projection having a horizonal axis.
Claim 4
Dependent Claim
95 words
An electromagnetic brake as defined in claim 1, wherein said connecting means comprises a semi-cylindrical projection formed on the inner end of each of the wearing pads on said two end members, the wearing pad on the central member of said row having in opposite ends thereof semi-cylindrical recesses matching in shape said projections, and the pads on the members positioned between said central member and said two end members having on opposite ends thereof a semi-cylindrical projection and a correspondingly shaped recess, respectively, whereby the adjacent ends of said members are pivotally connected together.
