PROVISIONAL SPECIFICATION.
Improvements in Covers for Soaking Pits for Steel Ingots and for
Furnaces in which the Ingots are Put in from the Top instead
of through Side Doors.
I LEWIS RICHARDS of Derwent View Workington Cumberland Engineer,
do hereby declare the nature of this invention to be as follows:-
My invention consists of a metal frame part of which is to be filled with refractory
material, the bottom part fitting loosely into the upper end of the pit; the upper
surface of the cover is to extend beyond the sides of the pit and to have a lip turned
downwards and which is to dip into a channel more or less filled with suitable
granulated material such as sand or any other substance suited for the purpose and
by means of which the communication between the pit and the outer atmosphere is
shut off and thereby preventing to a certain extent the escape of heat and especially
keeping the top end of the pit hotter than with the present form of cover.
Dated this 7th day of January 1891.
