Blackstone Oil Engine

Installed in the Smithy Building

This is a single cylinder (Diesel) oil engine. As far as is known it is a standard production model, but it spent its working life as a demonstration unit in Barnsley Technical College. In this role, it could be put on load using a special brake wheel, and had the necessary dials and gauges for students to determine the Brake Horse Power and Indicated Horse Power that was developed.

The engine has two methods of starting, buy hand or by compressed air. When started on compressed air, a pressure in the region of 350 p.s.i . is required. The air receiver (tank) can be charged by using an electric compressor or once it is running, by using the engine its self acting as a compressor. To help starting the engine by hand, an ignition paper can be inserted into the cylinder, but even with this three people are required, two to turn the engine and a third to operate the controls.

This engine is current out of use, requiring a new pressure vessel for the starting air. This job is not a priority at present as the engine does not have a suitable load to run against. In the past the engine had been used to power the lighting in the Smithy building in which it is installed, however the generator proved to be of an unsuitable design and has been removed. The long term plan is to install line shafting from this engine across the roof of the building to allow it to drive the large hammers and presses that are adjacent.
