Denaby’s Inventor

We have frequently had occasion to mention a number of clever inventions of Mr Albert G. Gulliford, head lamp man at Denaby and Cadeby colliery, who has now introduced a device which, when fixed to miner’s lamps will warn them when the atmosphere is dangerous and they should leave the pit.

With the use of electric miner’s lamps the danger of lack of warning when gasses about has hitherto existed – a warning which the old oil lamps gave immediately.

All the miner will have to do to test the atmosphere with this device will be to turn a screw and the tiny light will glow in a perforated tube at the side of the lamp.

If there is any gas at all the glow will become brighter, and the light in the lamp will become correspondingly dull. If there is 3%. or more gas in the atmosphere it will fuse a thread of platinum wire and both lights will go out. The miner will then turn a screw to bring the light of his lamp back again and get out of the pit as soon as he can.

The Safety in Mines Research Board, who made Mr Gulliford a grant to carry on his experiments, has tested the device at its lavatories and in the mines, and it has been tried successfully also on the Edison Lamps such as are worn by the American miners.

The Denaby and Cadeby Main Collieries will adopt the invention of their lamp man as soon as it is on the market.
