HC Deb 14 March 1939 vol 345 c195
22. Mr. Pilkington

asked the Secretary for Mines whether his attention has been drawn to the side warrick control method of stopping runaway trucks, as described in page 424 of the Transactions of the Institute of Mining Engineers, volume 93, part VI, and used by the several Lancashire collieries; and whether he is satisfied that this is generally satisfactory?

Captain Crookshank

I am advised that the automatic side control warrick referred to is in use at four collieries in Lancashire and that when kept in proper adjustment it is an effective device for stopping runaways. Drop-warricks and tub arresters of various types are extensively used in all the coalfields, and His Majesty's inspectors of mines take every opportunity of advocating the use of such safety devices and getting them applied where they think necessary.
