Abstract
A rail expansion joint made of two slidably engaging parts, each part being identical in shape and having a full thickness portion welded to the rail and a half thickness portion adapted to overlap the corresponding portion of the other part, the free ends of these two portions having a saw-tooth profile engaging the corresponding teeth of the two portions of the other part.

In a rail expansion joint comprising a first part adjacent to and in sliding relationship to a second part, said first and second parts being identical to each other and being disposed in facing relationship such that the attitude of one is 180.degree. with respect to the attitude of the other, each said part comprising a first portion having a full cross-sectional thickness corresponding to the thickness of said rail, and a second portion having a cross-sectional thickness substantially half that of said first portion so that the two half portions of said first and second parts are in side-by-side sliding relationship to provide a full width section, the improvement consisting in that:
- each said portion of said first and second parts terminates in a sawtooth profile adapted to engage the complementary teeth of the two sawtooth portions of the other part,
- said second portion of each part extending completely beyond the complementary engaged sawtooth profiles of the first portion of the same part and the second portion of the other part, and extending to engage the first portion of the other part, and wherein
- the two second portions of said two parts are slidably assembled by means of screws or bolts inserted through circular holes made in one of said parts and passing through oblong parts made in the other said part, said circular holes and said slots being located, respectively, in said second portion at the base of each tooth of said second portion and opposite each gap between the teeth of said first portion.
Rail expansion joint, composed of two parts sliding on each other, each being fixed to the end of two consecutive rails, characterized in that said two parts are substantially identical and each comprises a portion with a full cross-sectional thickness corresponding to that of the rail, by which it is fixed at its end to the latter and a portion with a half-cross-sectional thickness overlapping the corresponding portion of the other part, the free ends of these two portions each terminating in a sawtooth profile engaging the corresponding teeth of the two portions of the other part, said rail expansion joint being further composed of supports made of thin metal which are attached to one of the two overlapping portions thereby covering the space existing between the free ends of the latter, on the upper edge and the lower edge of the joint.
Rail expansion joint, composed of two parts sliding on each other, each being fixed to the end of two consecutive rails, characterized in that said two parts are substantially identical and each comprises a portion with a full crosssectional thickness corresponding to that of the rail, by which it is fixed at its end to the latter and a portion with a half-cross-sectional thickness overlapping the corresponding portion of the other part, the free ends of these two portions each terminating in a sawtooth profile engaging the corresponding teeth of the two portions of the other part, the two parts of the joint being slidably assembled by means of screws or bolts inserted in circular holes made in one of the parts and passing through oblong slots made in the other part, said circular holes and said slots being located in the half-cross-sectional portion, respectively at the base of each tooth and opposite each gap between the teeth in the full cross-sectional thickness portion.
