US3558050A — Rail support device

Claim 1

Independent Claim 194 words

A railway track rail support device comprising in combination a tie and rail fastening means including a nut, a bolt having an oblong head and a shank, and a fastener located around said bolt and between said nut and the upper faces of the tie and of the adjacent flange of the rail, said tie having a substantially vertical passageway for receiving said head and a part of said shank and a substantially horizontal passageway which has an upper face and intersects the said vertical passageway, an elastically yieldable metal strip interposed between said head and said upper face of the horizontal passageway, said strip having in its center part an oblong opening whose length is slightly greater than the length of said head of said bolt and whose width is slightly greater than the width of said head but less than the length of said head, said metal strip being curved, when said fastening means is not yet tightened down, and having a concave face directed toward said upper face of the horizontal passageway, said metal strip bearing throughout its surface on said upper face when said nut is tightened on said bolt.

Claim 2

Dependent Claim 194 words

A railway track rail support device comprising in combination a tie and rail fastening means including a nut, a bolt having an oblong head and a shank, and a fastener located around said bolt and between said nut and the upper faces of the tie and of the adjacent flange of the rail, said tie having a substantially vertical passageway for receiving said head and a part of said shank and a substantially horizontal passageway which has an upper face and intersects the said vertical passageway, an elastically yieldable metal strip interposed between said head and said upper face of the horizontal passageway, said strip having in its center part an oblong opening whose length is slightly greater than the length of said head of said bolt and whose width is slightly greater than the width of said head but less than the length of said head, said metal strip being curved, when said fastening means is not yet tightened down, and having a concave face directed toward said upper face of the horizontal passageway, said metal strip bearing throughout its surface on said upper face when said nut is tightened on said bolt.

Claim 3

Dependent Claim 36 words

A device as claimed in claim 1, wherein said hOrizontal passageway is blind and extends from one lateral face of the tie beyond said vertical passageway an extent which allows placing said metal strip in position.

Claim 4

Dependent Claim 39 words

A device as claimed in claim 1, wherein said vertical passageway extends beyond the bottom of said horizontal passageway an extent sufficient to accommodate said head of said bolt and allow rotation of said head under said metal strip.

Claim 5

Dependent Claim 29 words

a device as claimed in claim 1, wherein said strip has a length between one half of the width of said tie and the effective width of the tie.

Claim 6

Dependent Claim 22 words

A device as claimed in claim 1, wherein said strip has a width slightly less than the width of said horizontal passageway.

Claim 7

Dependent Claim 24 words

A device as claimed in claim 1, wherein said strip has a variable cross section which decreases from its center part to its ends.

Claim 8

Dependent Claim 24 words

A device as claimed in claim 1, where in said strip has a width less than one half of the length of said strip.

Claim 9

Dependent Claim 140 words

A railway track rail support device comprising in combination a tie and rail fastening means including a nut, and a bolt having a head and a shank, said tie having a substantially vertical passageway for receiving said head and a part of said shank and communicating only with horizontal surfaces of said tie, and a substantially horizontal passage communicating only with vertical surfaces of said tie and having an upper face at an intersection with said vertical passageway, an elastically yieldable metal strip interposed between said head and said upper face and bearing on said upper face when said nut is tightened on said bolt, said metal strip having an opening therein, and means for passing the head of the bolt through said opening in a downward direction and for securing said bolt against subsequent removal upwardly through said opening.

Claim 10

Dependent Claim 140 words

A railway track rail support device comprising in combination a tie and rail fastening means including a nut, and a bolt having a head and a shank, said tie having a substantially vertical passageway for receiving said head and a part of said shank and communicating only with horizontal surfaces of said tie, and a substantially horizontal passage communicating only with vertical surfaces of said tie and having an upper face at an intersection with said vertical passageway, an elastically yieldable metal strip interposed between said head and said upper face and bearing on said upper face when said nut is tightened on said bolt, said metal strip having an opening therein, and means for passing the head of the bolt through said opening in a downward direction and for securing said bolt against subsequent removal upwardly through said opening.
