A machine for grinding parts projecting above the normal surface of rails, beams and like members comprises means for supporting the member, grinding means 32, Fig. 1, for removing the projecting parts, and constraining means for conforming the removing action of the grinding means to the normal contour of the member. As shown, applied to grinding the welded joint 33 of a rail 17, the latter is supported on rollers 16 pivoted in pedestals 15 mounted on a fixed base 11, and has the axis of its head 34 aligned with the centre of two axially-aligned rings 18, 19 mounted on a movable bed 12. Two further rings 22, 24 each having three equi-spaced rollers 23 arranged to ride on the inner edge of the rings 18, 19 are spaced apart by guideways 27 and counterbalancing bars 29. The grinding wheel 32, driven by a motor 31 mounted on a carriage 30 and attached to a frame 45 resiliently mounted in a second frame 45 movable along the guideways 27, is located with its axis centrally over the rail head 34 and in line with two feeler rollers 54 mounted in the frame 46 and spaced longitudinally on either side of the wheel. The periphery of the rollers which contacts the rail head is level with the wheel which is inclined so that its edge 32a grinds the welded joint in conformity with the adjacent rail surfaces. The frame 45, fitted with rollers 48, 52 and reciprocated along the guideways 27 through a crank and link mechanism 36, 35 by a motor 37, is also slowly rotated in order to grind the sides of the rail head by a chain and sprocket drive 63, 64, 39 driven by the same motor through a clutch 65 and shaft 40. The clutch may be operated by a lever 66 and retained in the engaged position by a spring- loaded lever mechanism 85, Fig. 6, acting against the action of a spring 67 mounted in telescoping tubes 68, 69. In operation, an adjustable stop 90 fixed to the ring 22 automatically stops the rotation of the carriage by contacting the lever 85 thereby releasing the clutch. Under the action of the spring 67, a member 77 on the clutch shaft contacts a switch and thus de-energizes the motor 37. A latch member 79 is also provided to limit the travel of the lever 66 so that the clutch may be disengaged while still allowing the motor to operate.

Regulating.-In a power plant in which feedwater is heated in a rotary feed-pump.by tapped steam from a prime-mover, the quantities of tapped steam and water supplied are regulated according to the quantity of excess steam available, and the speed of the pump is regulated according to the pressure in one of the tappings. Tapped steam from three stages 4, 5, 6, Fig. 1, of a turbine 3 driven by steam from a boiler 1 is supplied to a pump 9 drawing feed-water from a tank 8 and supplying it to a storage vessel 11. Steam from the lowest stage 7 cf the turbine is led into the tank 8. A pressure-operated device 13 in the boiler steam pipe 2 controls valves 15 - - 18 in the tapped steam pipes and a valve 14 in the pipe between the pump and the storage vessel. The speed of the pump is regulated by a pressure operated device 19 in the tapped steam pipe from the stage 4. The speed of the pump may also be controlled in dependence upon the difference in pressure between the tapped pressure and the counter pressure of the corresponding pump stage. The tapped steam may be led into water reservoirs 20, 21, 22, Fig. 5, between the stages of the feed-pump 9. The centrifugal pump 12 between the storage vessel and the boiler may be regulated in accordance with the boiler pressure or the difference of pressure in the boiler and in the storage vessel. The pressure in the storage vessel may be maintained constant. This may be effected by an additional pump placed between the pump 9 and the storage vessel, the speed of the additional pump being controlled in accordance with the pressure in the outlet pipe of the pump 9. In a modification, the storage vessel presure is maintained constant by increasing the number of steps in the pump 9 by means of runners, each step leading to outlets which are changed according to the pressure required. Each of the outlets 31, Fig. 8, from the additional steps may be fitted 'with two spring or weight operated valves 34 opening at different pressures. When the pressure is raised in one of the stages to the desired limit, the lower valve in the corresponding outlet is lifted, and when the pressure raises above the limit the upper valve is closed.
