Abstract: 461,971. Wall and ceiling coverings ; nonconducting coverings for heat. McIVOR & SONS, Ltd., R., and MILLS, T. Aug. 26, 1935, No. 23804. [Class 20 (iv)] [Also in Group XIII] Relates to means for attaching insulation and other slabs B to the surfaces A of walls, ceilings, ships' plating, and the like, comprising clamping bars or strips C covering the joints between adjacent slabs and projecting at their ends into cover-plates D which are secured to the surface to be covered by studs S or the like. According to the invention, the clamping bars C have inclined sides, and the coverplates D are each formed from a substantially flat polygonal plate having at least one of its corners or edges bent out of the plane of the plate so that when the plate is in position the bent edge or corner will be in the angle between adjacent clamping bars and bear on the inclined sides thereof. The studs, screws, or bolts S are disposed in longitudinal and transverse lines at the corners between adjacent slabs, and the bars C do not extend the full distance between adjacent studs or like members S. The cover - plates D, which are adapted to engage the ends of four meeting bars C, may be formed by bending inwardly as shown at 3, Fig. 7, the corners of a square plate, and such bent corners are adapted to engage the bars C as shown in Fig. 1. When the cover - plates D are secured by studs S, the latter are welded to the surface to be covered and engage apertures 6 in the plates, and nuts are screwed on to the studs. The plates D may, alternatively, be secured by screws or bolts which are screwed into, or pass through, the surface to be covered. The peripheral edges of the assembled slabs are enclosed by angle-bars 1, Figs. 1 and 2, which may be attached to the surface A by the studs or screws S ; such edges are provided at the corners with cover-plates D<2> formed with two flanges 5 and one inturned edge 3, and other cover-plates D<1> for co-operation with clamping bars C are formed with one flange 5 and two inturned edges 3. The slabs may be of asbestos, magnesia-asbestos composition, compressed cork or the like ; if desired, they may be provided with separate or integral facing sheets, for example, of asbestos-cement. In the construction shown in Fig. 14, the slabs B are provided on the deck, bulkhead, and shell surfaces A<1>, A<2>, A<3> of a ship, and the peripheral clamp bars C on each of these surfaces are arranged some distance inside the peripheral edges of the slabs, the corner joints being covered by angle-irons 7 secured by studs S. The frame members F project beyond the outer faces of the slabs and are protected by U-shaped nosings G of asbestos-cement secured by studs S. The upper edges of the nosings G serve as additional clamping means for the slabs B and facing sheets E. The slabs shown in Fig. 17 are of greater thickness than the members F, and the slabs shown in Fig. 18 are spaced from the surface A<1> by angle-bars 9. The meeting edges of the slabs B covering two surfaces meeting at an obtuse angle are covered by an angle-piece which is held in place by the adjacent cover-plates. At the edge of an insulating covering, a channel member may be fitted over the covering to provide a bearing for the ends of the clamping bars.
