Abstract

A support for supporting a power rail and a rail shield consisting of a generally C-shaped unitary member having a base portion adapted for securing said member to a railway crosstie or the like and means for detachably securing a generally L-shaped rail shield to the inner side of the vertical leg and upper horizontal arm of the C-shape.

Claims

1. A support member for supporting a power rail and a rail shield and being adapted to be secured to a railway crosstie or the like base structure, the member including a web having a pair of spaced-apart first and second limbs each having a free end and interconnected at the opposite end by an intermediate portion, the intermediate portion extending between opposed surfaces of the first and second limbs, the first limb having a face adapted to contact the railway crosstie or the like base structure and further having a power rail receiving element, the intermediate portion having an exterior groove, the longitudinal axis of which is disposed normal to the plane of the web, the second limb having an aperture formed in proximity to the free end thereof and further having an outwardly extending flange spaced apart from said aperture and extending about at least a portion of said aperture, said aperture adapted to receive a pin, the groove in said intermediate portion together with the space between the outwardly extending flange and the pin when received in said aperture both adapted to accommodaTe portions of said rail shield, and cooperating to removably secure the rail shield to the support member.

2. A support member as claimed in claim 1, wherein said web has an inner flange disposed in a plane normal to the plane of the web said inner flange commencing at the groove and terminating in proximity to the aperture and forming an elongated surface adapted to contact and stabilize the rail shield when accommodated in said groove and space.

3. A support member as claimed in claim 2, wherein said aperture extends generally parallel to said groove and said outwardly extending flange is formed in part by a portion of the inner flange and in part by an outer flange disposed on the side of the second limb opposite the inner flange and commencing at the free end of the second limb, said outwardly extending flange being V in shape.

4. In combination, a support member, a shield and a pin, the support member being adapted to be secured to a railway crosstie or other base structure and including a generally C-shaped web having a pair of spaced-apart first and second limbs, each having a free end and interconnected at the opposite end by an intermediate portion, the intermediate portion having a surface in a plane normal to the plane of the web and extending between opposed surfaces of the first and second limbs, the first limb having a face adapted to contact the rail tie and further having a power rail receiving element, the intermediate portion having a groove, the longitudinal axis of which being disposed normal to the plane of the web, the second limb having an aperture formed in proximity to the free end thereof for receipt of the pin, the shield commencing at a first surface extending in a generally L-shaped and terminating in a V-shaped portion, the shield being so adapted that when the pin is positioned within the aperture, the first surface is positioned within the groove, the L-shaped portion contacts the inner flange and the V-shaped portion is positioned between the V-shaped projection and the pin.
