172,871. Anderson, R. W. Dec. 29, 1920. Non-conducting coverings for heat.-In order to secure a heat-insulating covering 8, Fig. 2, to ships' bulkheads or similar surfaces 1 from which project stiffeners or like abutments 3 without the necessity of perforating the bulkhead 1, sheets of expanded metal or other metallic mesh 9 are placed over the insulation 8 and are drawn up tightly against it by means of a number of bars 10 placed exterior to the mesh 9 and engaged by bolts 5 and nuts 11 or similar tightening-means carried by the stiffeners 3. In the construction shown in Fig. 2, the web 2 of the stiffener is of greater depth than the insulation 8 and a local insulation 8a held in place by expanded metal 9<a> laced to the mesh 9 is necessary to cover the projecting portion of the web 2. Such local insulation 8<a> may also be held in place by lengthening the bolts 5, or, as shown in Fig. 8, by the use of auxiliary eye-bolts 13 mounted on the bolts 5 and co-operating with a second series of rods 15. When the web 2 is of less depth than the insulation 8, no local insulation 8a is necessary, and, in some cases, where the stiffener 3 has a flange 2a, it may be necessary to perforate this flange 2a, as shown in Fig. 20, for the passage of the eye-bolts 20. In the modification shown in Fig. 18, the web 2<c> is of great depth and two flanges 2a are provided, the insulation 8, 8<b> and 8<c> being secured in position by means of the meshes 9, 9b and 9<c> and co-operating bars 10, 18<a>, and 18. At the corner between two bulkheads or other surfaces 1, 1<a>, Fig. 22, the mesh 9 is engaged by two sets of bars 10<a>, 10<b> arranged at right-angles, the rods 10<a> being drawn up by means of bolts 27 and nuts 29, and the rods 10<b> by means of nuts 32 and eye-bolts 30 mounted on the bolts 27.
