Abstract
The gauge and cess panels (3, 4) of a level crossing creep apart lengthwise of the track (1, 2) and need closing up again from time to time. A device (5, 24) for this consists of a member (8, 26) that engages under or over a rail (1) and has a portion (10, 27) extending transversely to the rail carrying a cam (6) or screw (28) for engaging the end of a panel (3, 4). When the cam or screw is turned, the reaction from the panel (3, 4) jams the member (8, 26) on the rail (1), and further turning forces the panel lengthwise of the track. Another device for gauge panels is a two armed toggle (29) with a cam (31) at its pivot (30), the arms (29) being in a shallow V with their free ends (32) braced against the insides of the rails (1).
Claims5
A device for adjusting level crossing panels in combination with a two rail track, each of said rails having a generally horizontal base flange, an upright web and a head, and a level crossing with associated panels, the surface of the crossing being substantially flush with tops of the rail heads, the device being for adjusting the panels longitudinally of the track and comprising a bar with an upper face at one end and two abutments proud of said face and spaced longitudinally on the bar with a gap therebetween, and an element with an abutment surface carried by the other end of the bar and adjustable with a mechanical advantage to advance said abutment surface in a direction transverse to the bar and parallel to and above the level of said upper face when said upper face is horizontal, wherein the device is arranged adjacent one end of the crossing with said upper face against an underside of one of the rails and with the abutments engaging opposite edges of the base flange of said one rail, so that the bar extends transversely of the track, and with the abutment surface of said element engaging an edge of one of said panels at said one end of the crossing.
A device for adjusting level crossing panels longitudinally of a railway track, the device comprising two bars hinged end-to-end and capable of assuming a shallow V-configuration, an element with an abutment surface carried at the vertex of the V and adjustable with a mechanical advantage to advance said abutment surface in the direction to which the V points, and electrically non-conductive pads at the ends of the bars remote from the hinged ends.
