Abstract
Abstract A unitized insulating element for use with a steel cross tie is provided. The insulating element is operative to electrically insulate the rail from the steel tie, from retaining elements associated with the tie which prevent lateral movement of the rail relative to the tie and from rail anchors which prevent longitudinal movement of the rail relative to the tie. The insulating element permits use of the rail as an on-line signal control conveying device when steel ties are used and is configured as a tie plate substitute from providing an inwardly-directed cant for the rail to be retained thereon.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
161 words
A unitized insulative element for use with a steel cross tie having associated rail retaining elements for preventing lateral movement of a rail on such steel tie and rail anchors for preventing longitudinal movement of such rail relative to such steel tie, said unitized insulative element comprising: insulating base means adapted to be positioned between such rail and such steel tie for insulating the one from the other; upwardly depending insulating detent means for insulating such rail retaining elements of such tie from such steel tie, said upwardly depending detent means being configured to provide means, relative to said base means and such associated rail retaining elements, for preventing movement of said unitized insulative element in a direction parallel to such railroad rail and in a direction normal thereto; and downwardly depending insulating means for insulating such steel tie from such rail anchors and additionally, for preventing movement of said unitized insulative element in a direction parallel to such railroad tie.
Claim 2
Dependent Claim
161 words
A unitized insulative element for use with a steel cross tie having associated rail retaining elements for preventing lateral movement of a rail on such steel tie and rail anchors for preventing longitudinal movement of such rail relative to such steel tie, said unitized insulative element comprising: insulating base means adapted to be positioned between such rail and such steel tie for insulating the one from the other; upwardly depending insulating detent means for insulating such rail retaining elements of such tie from such steel tie, said upwardly depending detent means being configured to provide means, relative to said base means and such associated rail retaining elements, for preventing movement of said unitized insulative element in a direction parallel to such railroad rail and in a direction normal thereto; and downwardly depending insulating means for insulating such steel tie from such rail anchors and additionally, for preventing movement of said unitized insulative element in a direction parallel to such railroad tie.
Claim 3
Dependent Claim
53 words
The unitized insulative element according to claim 1 in which said insulating base means is formed having a generally wedge shape for canting the rail to be supported thereon in a direction toward one of said upwardly depending detent means for providing a slight inward cant to the rail to be supported thereon.
Claim 4
Dependent Claim
20 words
The unitized insulative element according to claim 1 in which said unitized insulative element is formed from high density polyethylene.
Claim 5
Dependent Claim
46 words
The unitized insulative element according to claim 1 in which said upwardly depending insulating detent means are deformable along with such rail retaining elements of such steel tie for insulating such rail from such tie when such elements are placed in retaining engagement wih such rail.
Claim 6
Dependent Claim
26 words
The unitized insulative element according to claim 1 in which said upwardly depending detent means are oriented at right angles to said downwardly depending insulating means.
Claim 7
Dependent Claim
131 words
In combination, a steel tie, having integrally formed means for retaining a rail thereto and preventing movement of such rail relative to said tie, said rail being prevented from longitudinal movement relative to said tie by the use of rail anchors attached to such rail and which butt against a portion of said tie, and a unitized insulative member for electrically insulating the rail from said steel tie, said integrally formed retaining means and such rail anchors such that such rail may be employed for signal control purposes without being shorted out by said tie, said retaining means or such rail anchors, said unitized insulative member being configured having at least one means for preventing movement of said member relative to said steel tie in a direction parallel to the rail.
Claim 8
Dependent Claim
131 words
In combination, a steel tie, having integrally formed means for retaining a rail thereto and preventing movement of such rail relative to said tie, said rail being prevented from longitudinal movement relative to said tie by the use of rail anchors attached to such rail and which butt against a portion of said tie, and a unitized insulative member for electrically insulating the rail from said steel tie, said integrally formed retaining means and such rail anchors such that such rail may be employed for signal control purposes without being shorted out by said tie, said retaining means or such rail anchors, said unitized insulative member being configured having at least one means for preventing movement of said member relative to said steel tie in a direction parallel to the rail.
Claim 9
Dependent Claim
39 words
The unitized insulative element according to claim 6 in which said unitized insulative member is configured having means for providing a slight inward cant to such rail when such rail is supported by said insulative member on said tie.
Claim 10
Dependent Claim
20 words
The unitized insulative element according to claim 6 in which said unitized insulative member is formed from high density polyethylene.
Claim 11
Dependent Claim
68 words
The unitized insulative element according to claim 6 in which said unitized insulative member includes: insulating base means, adapted to be positioned between such rail and said steel tie for electrically insulating one from the other; upwardly depending insulating detent means for electrically insulating said integrally formed retaining means from said steel tie; and downwardly depending insulating means for electrically insulating said steel tie from such rail anchors.
Claim 12
Dependent Claim
34 words
The unitized insulative element according to claim 9 in which said upwardly depending insulation detent means are deformable for accommodating any movement of said integrally formed retaining means into retaining association with such rail.
