IMPROVEMENTS IN AN INSULATED COVER FOR TORPEDO CARS

摘要

Improvements to an insulating cover for covering an opening in a torpedo car are disclosed. The insulating cover includes upper and lower wire mesh layers an d an insulating layer positioned between the wire mesh layers. A support rod may be provided which extends beyond the ends of the upper and lower wire mesh layers. A pair of support rods in an "X" configuration may be provided which extend beyond the side edges of the uppe r and lower wire mesh layers. Tie devices secure the wire mesh layers together and hold the insulating layer in position. At least one ferromagnetic plate is provided, whereby each ferromagnetic plate provides a lift point for lifting the insulating cover, such as with an electromagnet or the like. Methods for constructing the embodiments of the insulating cover are also disclosed.
