OMC-2 Beam Engine Kit

$375.00

This electromagnetic Beam Engine is based, in part, on the early engines of Charles Grafton Page. Two banks of coils are energized in turn causing an armature plate to rock. This movement is transmitted via connecting rods, a beam and crank to a timing shaft and power take off pulley.  Two sets of timing points are activated by cams and this arrangement is fully adjustable. A flywheel ensures momentum.

SKU: OMC-02 Category:

The OMC-2 Beam Engine is based on original designs from 1836 – 1860 and working on 4.5 volts dc, this fully working model engine kit represents how the pioneers of the time tried to mimic steam engine technology in their efforts to use the newly discovered phenomenon of electricity.

 

Many configurations of parts were tried and the OMC-2 Beam Engine is typical of the many reciprocating designs that were developed.

There are over 150 parts to assemble but as no machining or soldering is necessary, this kit is suitable for model makers of all abilities.

 

Great attention to detail has been taken to ensure that all of the parts are made in the style of the period. The brass pillars, finials and terminal connections are typical of the times and the flywheel has been described as a “work of art”.

 

OMC-23-Series-Two-009-300x199The coils of this model are arranged in two banks, just like the originals and are charged intermittently causing the armature plate to rock. This movement is transmitted via connecting rods and a beam to a shaft and power takeoff pulley.

 

The “break piece” or contact blades are fitted next to the shaft and are mounted in two contact housings and operated by cams fitted to the shaft. These contact blades are constructed of nickel silver and fitted with high quality silver nickel contacts to ensure long lasting trouble free operation.

 

OMC-23-Series-Two-010These timing assemblies are mounted on moveable brackets allowing for adjustment to the model’s timing. They are in turn attached to an authentically styled base plate.

 

This arrangement makes it possible to achieve minimum mechanical resistance at the cams with further fine tuning possible with the timing plate screws that establish how long the timing blades are in contact.

 

This model engine kit is fitted with a fully working on/off switch of period design that incorporates a ball and spring. This makes demonstrating the engine much easier.

 

OMC-23-Series-Two-011-300x212Produced from high quality brass, silver steel and zinc coated steel with copper windings on iron cores the model is mounted on a classic wooden base that also conceals the battery box and other modern considerations.

 

A detailed and illustrated instruction manual is provided and the components are packed in numbered bags that correspond to sections in this manual.
