Article breaking apparatus for mounting on an arm of a suitable vehicle, the apparatus having a pair of hydraulically operated jaws (12, 24), the first jaw (12) of the pair having first and second mutually perpendicular article supporting surfaces (14, 16) and the second jaw having an article engaging surface (26). The jaws (12, 14) are movable about a first pivot axis (22) between an article receiving position in which the first article supporting surface (14) and the article engaging surface (26) diverge away from the first pivot axis (22) and an article breaking position in which said surfaces (14, 26) diverge towards the first pivot axis (22). When an article (82) is located between the jaws (12, 24) and the jaws (12, 24) move from the receiving to the breaking position, the article (82) will be urged towards the second article supporting surface (16) and held there against until broken by the relative movement of the said surfaces (14, 26).
Article breaking apparatus, the apparatus including:
Article breaking apparatus according to any of the preceding claims, in which the first jaw includes a second article supporting surface inclined relative to the first article supporting surface and closer to the first pivot axis, whereby, as the jaws move from the article receiving to the article breaking position, an article located between the jaws will be urged towards the second article supporting surface and held thereagainst until broken by relative urging together of the first and second article supporting surfaces and the article engaging surface.
Article breaking apparatus according to any of the preceding claims, in which the first article supporting surface is arranged to support an article with its longitudinal axis transverse to the jaws and at an angle relative to the direction of motion of the jaws.
Article breaking apparatus according to any of the preceding claims, in which the article engaging surface includes a blade.
Article breaking apparatus according to any of the preceding claims, in which the first pivot means includes a thrust bearing.
Apparatus for breaking rails of the aforesaid type, the apparatus being according to any of the preceding claims.
A suitable vehicle as hereinbefore defined, the vehicle being fitted with article breaking apparatus according to any of the preceding claims.
An article breaking apparatus substantially as hereinbefore described and with reference to the accompanying drawings.
An apparatus for breaking rails of the aforesaid type substantially as hereinbefore described and with reference to the accompanying drawings.
A suitable vehicle substantially as hereinbefore described and with reference to the accompanying drawings.
A method of breaking rails of the aforesaid type substantially as hereinbefore described and with reference to the accompanying drawings.
Any novel subject matter or combination including novel subject matter disclosed herein, whether or not within the scope of or relating to the same invention as any of the preceding claims.
Dependencies are inferred from the claim text.
