Abstract

Abstract This disclosure relates to a rail mounting assembly for use on concrete ties including an electrical insulating, sound deadening, vibration damping, rubber tie pad having positioning openings therein to positively locate the pad on a concrete tie and beads formed thereon to prevent slippage of the tie pad on the tie. The assembly also includes rubber rail fastener pads to electrically isolate the metal rail fastener from the rail and to prevent slippage of the rail.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 77 words
A rail mounting tie pad made of an elastomeric, electrically insulating, vibration damping material for use with rails secured upon concrete ties, comprising: central rail supporting means having upper and lower surfaces for respectively engaging the rail and tie; a plurality of longitudinal beads formed on said surfaces; and spaced frustoconical boss means for positioning said pad on a tie, said positioning means being integrally formed with said rail supporting means and disposed at opposite ends thereof.
Claim 2
Dependent Claim 77 words
A rail mounting tie pad made of an elastomeric, electrically insulating, vibration damping material for use with rails secured upon concrete ties, comprising: central rail supporting means having upper and lower surfaces for respectively engaging the rail and tie; a plurality of longitudinal beads formed on said surfaces; and spaced frustoconical boss means for positioning said pad on a tie, said positioning means being integrally formed with said rail supporting means and disposed at opposite ends thereof.
Claim 3
Dependent Claim 31 words
The tie pad defined in claim 1 wherein said beads located upon the upper and lower surfaces of said rail supporting means are disposed in the same direction and relatively offset.
Claim 4
Dependent Claim 32 words
The tie pad defined in claim 1 wherein said beads located upon the upper and lower surfaces of said rail supporting means are disposed at substantially right angles relative to one another.
Claim 5
Dependent Claim 28 words
The tie pad defined in claim 1 wherein said positioning means includes projecting bosses through which extend openings in said tie pad, located to receive rail securing bolts.
Claim 6
Dependent Claim 26 words
The tie pad defined in claim 1 including plural shock absorbing positioning feet located upon one surface of said rail supporting means and formed integrally therewith.
Claim 7
Dependent Claim 154 words
A removable rail fastener pad made of an elastomeric, electrically insulating, vibration damping material for use with a generally U-shaped metal rail fastener having spaced upper and lower legs, the upper leg being longer than the lower leg for holding down the rail base, comprising: body means for underlying the extending portion of the upper leg and engaging a rail base; wall means for engaging the greater portion of the side edges of the extending portion to electrically isolate the upper leg from the rail base; means located at one end of said body means for capturing the leading edge of the upper leg; mounting means located at the opposite end of said body means for mounting said fastener pad upon the rail fastener between the upper and lower legs; and means depending from said body means for engaging the leading edge of the lower leg to electrically isolate it from the rail base.
Claim 8
Dependent Claim 154 words
A removable rail fastener pad made of an elastomeric, electrically insulating, vibration damping material for use with a generally U-shaped metal rail fastener having spaced upper and lower legs, the upper leg being longer than the lower leg for holding down the rail base, comprising: body means for underlying the extending portion of the upper leg and engaging a rail base; wall means for engaging the greater portion of the side edges of the extending portion to electrically isolate the upper leg from the rail base; means located at one end of said body means for capturing the leading edge of the upper leg; mounting means located at the opposite end of said body means for mounting said fastener pad upon the rail fastener between the upper and lower legs; and means depending from said body means for engaging the leading edge of the lower leg to electrically isolate it from the rail base.
Claim 9
Dependent Claim 21 words
The rail fastener pad defined in claim 6 including antislip means disposed upon the rail engaging surface of said body means.
Claim 10
Dependent Claim 16 words
The rail fastener pad defined in claim 7, wherein said antislip means includes plural longitudinal beads.
Claim 11
Dependent Claim 32 words
The rail fastener pad defined in claim 6 wherein said means located at said opposite end includes a thickened portion of said body having wedge-shaped friction ribs formed on one surface thereof.
Claim 12
Dependent Claim 199 words
A rail mounting assembly for use in securing a rail on a concrete tie with generally U-shaped metal rail fasteners having spaced upper and lower legs and engaging a rail base, the upper leg being longer than the lower leg for holding down the rail base, comprising: a rail mounting tie pad made of an elastomeric, electrically insulating, vibration damping material including central rail supporting means and spaced frustoconical positioning means located at opposite ends of said rail supporting means; and a removable fastener pad made of an elastomeric, electrically insulating, vibration damping material including body means for underlying the extending portion of the upper leg, wall means for engaginG the greater portion of the side edges of the extending portion to electrically isolate the upper leg from the rail base, means located at one end of said body means for capturing the leading edge of the upper leg, mounting means located at the opposite end of said body means for mounting said fastener pad upon the rail fastener between the upper and lower legs, and means depending from said body means for engaging the leading edge of the lower leg to electrically isolate it from the rail base.
Claim 13
Dependent Claim 199 words
A rail mounting assembly for use in securing a rail on a concrete tie with generally U-shaped metal rail fasteners having spaced upper and lower legs and engaging a rail base, the upper leg being longer than the lower leg for holding down the rail base, comprising: a rail mounting tie pad made of an elastomeric, electrically insulating, vibration damping material including central rail supporting means and spaced frustoconical positioning means located at opposite ends of said rail supporting means; and a removable fastener pad made of an elastomeric, electrically insulating, vibration damping material including body means for underlying the extending portion of the upper leg, wall means for engaginG the greater portion of the side edges of the extending portion to electrically isolate the upper leg from the rail base, means located at one end of said body means for capturing the leading edge of the upper leg, mounting means located at the opposite end of said body means for mounting said fastener pad upon the rail fastener between the upper and lower legs, and means depending from said body means for engaging the leading edge of the lower leg to electrically isolate it from the rail base.
Claim 14
Dependent Claim 46 words
The rail mounting assembly defined in claim 10 wherein: antislip means comprising plural longitudinal beads is formed upon the upper and lower surfaces of said rail support element; and antislip means comprising plural longitudinal beads is disposed upon the rail engaging surface of said body means.
