This'"mvention relates to protective linings exposed, unprotected surface underneath. for vessels, and relates more particularly to Reinforcement of said lining b any ordian improved method and means for supportnary means, such as, for examp e, interposbe ing a flat wire mesh, anded metal (coma a plied to the interior of a vessel in monly termed metal ath), or the like,

After said mesh has been 80 away from the walls of a vessel, leaving an ably mounted upon the inner surfaces of said 2 moans chamber, a protective lining for the inner surfaces of said chamber to a depth to about the extent of a line 7 of Fig. 2, may be applied thereover. Said protective lining may comprise a plastic coating 8, applied as hereinbefore described over said wire mesh. As will be clearly seen from Fig. 3, the strands of wire 1, bent alternately inwardly and outwardly from the plane of said interwoven points 2, to said points 3, will afford a greater reinforcement for said protective lining, binding and holding the same throughout substantially its entire depth, as illustrated in said Fig. 3 at the points 9.

It is to be understood that I have for purposes of illustration only shown one form of wire mesh which may be adapted to reinforce a plastic lining applied thereover. Obviously, other forms of wire mesh may be employed, and which may be adapted to produoe the permeating effect which the invention affords I claim as my invention 2- 1. In combination, a chamber having a nular heat-resistant lining on an inner wall thereof, and reinforcing means for said lining, comprising a crim d wire mesh, the

' crests and troughs of said crimps 1 ing in parallel planes and spaced a greater istance from each other than twice the diameter of said wire.

2. In combination, a vessel having a granular heat-resistant lining on an inner wall thereof, and reinforcing means for said lining comprising in combination a wire mesh interwoven in a common plane, the unwoven strands of said mesh being crimped and spaced in an inward and outward direction from said interwoven plane a distance equal to the depth of one crimp.

3. In combination, a vessel having a granular heat-resistant lining on an inner wall thereof, and reinforcin means for said lining comprising in combination a wire mesh interwoven in a common plane, the unwoven strands of said mesh being crimped in an alternate inward and outward direction from each interwoven plane to an extent at least substantially twice the diameter of the wire strands com rising said mesh.

4. In com ination, a. vessel having a granular heat-resistant lining on an inner wall thereof, and reinforcing means for said lining comprising in combination a oementitious material having imbedded therein a wire mesh, the strands comprising said mesh being crimped so that the crests of said crimped strands are s need from the troughs of said crimps in a p ane parallel to the plane of the mesh, a distance greater than twice the diameter of the strands comprising said mesh.

In testimony whereof I aflix my signature.
