Abstract
A railroad track mounting arrangement for mounting a detecting device in proximate relation to a rail head portion of a section of rail includes first and second V-shaped rail clamp member which exhibit inner contours substantially equivalent to the outer contour of the rail base such that a tight fit is achieved therebetween. A side mounting portion extends from the rail clamp members at a point where, upon installation of the rail clamps, the side mounting portions are in close proximity to the rail base. A mounting bracket secures to the side mounting portion and has a base portion for holding in a secure manner the detecting device. A nut and bolt arrangement secures the rail clamps together and, in the event of overtightening, fractures, thereby insuring positive detection of a faulty installation.

A railroad track mounting arrangement for securing a monitoring device to a section of rail having a rail head and rail base portion, said mounting arrangement comprising:
- (a) a first rail clamp member slidably fitted over one side of the rail base;
- (b) a second rail clamp member slidably fitted over an opposite side of the rail base to the side on which said first rail clamp member is slidably fitted;
- (c) said first and second rail clamp members including respectively a first and second lower portion which fit against an under portion of the rail base, a first and second upper portion which fit against an upper sloped portion of the rail base, and a first and second rear connecting portion which connect, respectively, said first upper portion to said first lower portion and said second upper portion to said second lower portion of said first and second rail clamp members;
- (d) at least one of said first and second rail clamp members being formed such that an inner contour results by such connection of said first and second upper portions to said first and second lower portions, said inner contour conforming substantially in shape to an outer contour of the rail base;
- (e) securing means engaging said first and second rail clamp members for securing said first and second rail clamp members to one another across the one and opposite sides of the rail base;
- and
- (f) a side mounting portion formed on each of said first and second rail clamp members in a longitudinal axis of said first and second rail clamp members, each of said side mounting portions having a securing opening formed therein such that the monitoring device can be mounted thereon, said side mounting portions extend downward beyond the depth of said first and second lower portions of said first and second rail clamp members and further extend upward beyond the height of the rail base.
A railroad track mounting arrangement for securing a monitoring device to a section of rail having a rail head and rail base portion, said mounting arrangement comprising:
- (a) a first rail clamp member slidably fitted over one side of the rail base;
- (b) a second rail clamp member slidably fitted over an opposite side of the rail base to the side on which said first rail clamp member is slidably fitted;
- (c) said first and second rail clamp members including respectively a first and second lower portion which fit against an under portion of the rail base, a first and second upper portion which fit against an upper sloped portion of the rail base, and a first and second rear connecting portion which connect, respectively, said first upper portion to said first lower portion and said second upper portion to said second lower portion of said first and second rail clamp members;
- (d) at least one of said first and second rail clamp members being formed such that an inner contour results by such connection of said first and second upper portions to said first and second lower portions, said inner contour conforming substantially in shape to an outer contour of the rail base;
- (e) securing means engaging said first and second rail clamp members for securing said first and second rail clamp members to one another across the one and opposite sides of the rail base;
- and
- (f) a side mounting portion formed on each of said first and second rail clamp members in a longitudinal axis of said first and second rail clamp members, each of said side mounting portions having a securing opening formed therein such that the monitoring device can be mounted thereon, and third and fourth rail clamp members, said third rail clamp member slidably fitted over one side of the rail base at a predetermined distance along the section of rail relative to said first rail clamp member, said fourth rail clamp member slidably fitted over the opposite side at a predetermined distance along the section of rail relative to said second rail clamp member, said third and fourth rail clamp members being secured together by a second securing means.
A railroad track mounting arrangement for securing a monitoring device to a section of rail having a rail head and rail base portion, said mounting arrangement comprising:
- (a) a first rail clamp member slidably fitted over one side of the rail base;
- (b) a second rail clamp member slidably fitted over an opposite side of the rail base to the side on which said first rail clamp member is slidably fitted;
- (c) said first and second rail clamp members including respectively a first and second lower portion which fit against an under portion of the rail base, a first and second upper portion which fit against an upper sloped portion of the rail base, and a first and second rear connecting portion which connect, respectively, said first upper portion to said first lower portion and said second upper portion to said second lower portion of said first and second rail clamp members;
- (d) at least one of said first and second rail clamp members being formed such that an inner contour results by such connection of said first and second upper portions to said first and second lower portions, said inner contour conforming substantially in shape to an outer contour of the rail base, said inner contour of said at least one of said first and second rail clamp members is shaped to securely contact and be supported by the top and bottom contour of the rail base;
- (e) securing means engaging said first and second rail clamp members for securing said first and second rail clamp members to one another across the one and opposite sides of the rail base;
- and
- (f) a side mounting portion formed on each one of said first and second rail clamp members in a longitudinal axis of said first and second rail clamp members, each of said side mounting portions having a securing opening formed therein such that the monitoring device can be mounted thereon, said side mounting portions extend from said first and second rail clamp members at a point adjacent said inner contoured portion such that, upon installation of said first and second rail clamp members, said side mounting portions contact the front facing portion of the rail base.
