Oblique expansion gap for between consecutive sections of railway tracks

Abstract

An improved expansion gap designed to permit expansion tolerances between consecutive rail end sections which is comprised of corresponding oblique end cuts for the stock rail head with the combination of conventional squared-end cuts for both the web portion and the stock rail foot of the adjacent rail section ends; having connecting and fastening means so arranged as to produce a no-gap resultant effect, therefore achieving a continuous and uninterrupted surface on the rail end sections to provide for the smooth transfer of the wheels of railway vehicles across these rail end sections, while allowing for expansion tolerances yet able to greatly reduce/overcome the impact and pounding of the rolling wheels. The practical angles of obliqueness for the stock rail head being between 10 degrees to 60 degrees and a 30-degree of obliqueness is considered very suitable.

1 . An expansion gap for part of a railway track capable to provide for the smooth transfer of rolling train wheels with minimum impact and pounding disposed on normal sleepers comprising: 
 a first rail section end having an oblique-end cut for the stock rail head and conventional squared-end cut for both the web portion and stock rail foot all with a common point centre;    a second rail section end having a corresponding oblique-end cut for the stock rail head and conventional squared-end cut for both the web portion and the stock rail foot all with a common point centre;    non positive fastening means for connecting the said first rail section end with said second rail section end;    the connection arranged to provide an oblique-end expansion gap for the consecutive sections of the stock rail head and combination of conventional squared-end expansion gap for both the web portion and the stock rail foot;    an expansion gap for part of a railway track as defined in the above, the said angle of obliqueness being 10 degrees to 60 degrees;    an expansion gap for part of a railway track as defined in the above, the said angle of obliqueness being 30 degrees;    an expansion gap for part of a railway track as defined in all of the above, being applicable for the upgrading of already-in-use-constructed railway tracks having only squared-end expansion gaps.
