Successive filled moulds are stacked by the telpher on a wheeled heat and moisture insulated carriage 17 and the telpher encloses each stack on a carriage 17 by a portable heat and moisture insulated setting chamber 16. The carriages 17 are then transported by a conveyer belt, or chain 28, along a track 21 as the mould stacks are heated by thermostatically controlled resistance elements of the chamber 15 supplied with current, either via an overhead line, or through the carriage wheels 18 from a live rail. At a location 30, the telpher removes the setting chamber 16 to a location 31, the moulded beams are removed to a further carriage at 32, and the empty moulds to a stack 33 which is then replaced by the telpher, together with the setting chamber, on an empty carriage at 30 which is returned, either by a further rail track or by the telpher, to its initial position in which the chamber 16 and the stack are separated by the telpher. The moulds 1 comprise open-ended trays, and the steel frames 3 include outwardly extending upper flanges, and out-turned, e.g. at 45 degrees, lower edges which locate against the mould 1. The lengths of the beams cast may be varied by end closure walls secured by pins fastened to the frame end wall and received through lugs outwardly projecting from the end closure walls. The end closure walls may be profiled to produce, on the beam ends, vertically extending tapering ribs.

In the embodiment described which shows two cutting tool assemblies each tool 10 being mounted in a pivotable tool carrier 7 secured to a cross-slide 11, radial movement of the tools being effected by spring biased levers 3 which in turn are actuated by an oval cam profile 2 rotating concentrically with the piston 1 and which constitute the first means. The cross slide 11 is mounted on a saddle 13 and is actuated by a feed screw 16 which is operated by a lever 18 which engages a template 20 secured to the machine; whereby traversing of the slide 13 causes rotation of the screw 16, by the action of the lever and template, to displace the cross slide causing further radial movement of the cutting tools 10. The latter mechanism constitutes the second means which by simultaneous operation with the first means effects the production of the required profile on the piston.
