For showing the conversion from electrical energy via mechanical, to potential energy by winding up a weight on a cord.
One end of the 6mm.
steel shaft carries an aluminium 'V' pulley 56 mm.
diameter, and the other end is fitted with a cord anchoring collar.
Supplied complete with driving belt.
To show the forces which can be exerted during thermal expansion or contraction.
Comprising a heavy cast iron frame 340x120x100mm with slotted end pillars to carry a stout iron bar.
The bar is threaded at one end for a large tensioning nut and has holes at the other end to accommodate the cast iron breaking bars.
Supplied complete with ten breaking bars.
This model uses the same basic assembly as the motor, but is mounted on a baseplate 230 x 90 mm approx.
which also carries a hand-drive pulley 120mm.
diameter coupled to the smaller dynamo pulley by a rubber belt to give a step-up ration.
Electrical output is via a pair of 4mm sockets.
The model may also be used as a motor on a 6-8 V D.C. supply.
To show conversion of mechanical energy into electrical energy.
Turbine with transparent cover, inlet and outlet tubes, directly connected to a dynamo. Fitted on base.
Operation of a commercial steam engine is well illustrated with this working model.
The extra large size unit is provided with a horizontal boiler with a whistle, safety valve, steam gauge, on metal base.
Operates on 220V A.C. 50 Hz.
