Railroad rail cold saw

A railroad rail cold sawing device for securement about a railroad rail having a central web and flanges connected to opposite ends of the web, said device comprising:

• (a) a circular sawing section having a cold circular saw blade;
• (b) a drive section;
• (c) connection means removably connecting said drive section and said sawing section for causing rotation of said cold circular saw blade;
• and
• (d) clamping means for removably clamping said sawing section and said drive section to said central web of said railroad rail, said clamping means including:
• (i) support means for supporting a respective section on an upper one of said flanges;
• (ii) fixed clamping leg means fixedly secured to said support means for clamping one side of said central web;
• (iii) pivotal clamping elbow means pivotally secured to said support means for clamping an opposite side of said central web;
• (iv) drive means connected to said support means and said pivoting clamping leg means for pivoting said pivoting clamping leg means into clamping relation with the opposite side of said central web to secure the respective section to the railroad rail, said drive means including:
• (A) piston-cylinder means for pivoting said clamping elbow means into clamping relation with the opposite side of said central web to secure the respective section to the railroad rail, said piston-cylinder means including a substantially vertically movable piston;
• and
• (B) clamping hinge means for connecting said piston to said pivotal clamping elbow means;
• (C) wherein movement of said piston in one direction causes said pivoting clamping elbow means to clamp onto the opposite side of said central web, and movement of the piston in the opposite direction causes said pivotal clamping elbow means to unclamp from the opposite side of said central web;
• (v) clamping foot means secured to the free end of said pivotal clamping elbow means for clamping onto the opposite side of said central web, said clamping foot means having an exposed concave pivot foot face which is highlighted by four equally spaced corner points for firmly clamping onto the opposite side of said central web, said exposed concave pivot foot face having concave peripheral edges defined between each of said corner points;
• and
• (vi) pivotal foot holder means secured to the free end of said pivotal clamping elbow means for pivotally securing said clamping foot means to the free end of said pivotal clamping elbow means.

A clamping assembly for clamping a railroad rail cold sawing device about a railroad rail having a central web and flanges connected to opposite ends of the web, said clamping assembly comprising:

• support means for supporting a respective section of the device on an upper one of said flanges;
• fixed clamping leg means fixedly secured to said support means for clamping one side of said central web;
• pivotal clamping leg means pivotally secured to said support means for clamping an opposite side of said central web;
• and
• drive means connected to said support means and said pivoting clamping leg means for pivoting said pivoting clamping leg means into clamping relation with the opposite side of said central web to secure the respective section to the railroad rail;
• clamping foot means secured to the free end of said pivotal clamping leg means for clamping onto the opposite side of said central web, said clamping foot means having an exposed concave pivot foot face which is highlighted by four equally spaced corner points for firmly clamping onto the opposite side of said central web, said exposed concave pivot foot face having concave peripheral edges defined between each of said corner points;
• and
• pivotal foot holder means secured to the free end of said pivotal clamping leg means for pivotally securing said clamping foot means to the free end of said pivotal clamping leg means.

A clamping assembly for clamping a railroad rail cold sawing device about a railroad rail having a central web and horizontally oriented flanges connected to opposite ends of the web, said clamping assembly comprising:

• support means for supporting a respective section of the device on an upper one of said horizontally oriented flanges;
• fixed clamping leg means fixedly secured to said support means for clamping one side of said central web;
• pivotal clamping elbow means pivotally secured to said support means for clamping an opposite side of said central web;
• and
• drive means connected to said support means and said pivoting clamping leg means for pivoting said pivotal clamping elbow means into clamping relation with the opposite side of said central web to secure the respective section to the railroad rail and;
• said drive means includes:
• piston-cylinder means for pivoting said pivotal clamping elbow means into clamping relation with the opposite side of said central web to secure the respective section to the railroad rail, said piston-cylinder means including a substantially vertically movable piston;
• and
• clamping hinge means for connecting said piston to said pivotal clamping elbow means;
• wherein movement of said piston in one direction causes said pivoting clamping elbow means to clamp onto the opposite side of said central web, and movement of the piston in the opposite direction causes said pivoting clamping elbow means to unclamp from the opposite side of said central web.
