Abstract: 470,349. Partitions ; wall and ceiling coverings. OLSEN, A. C. Feb. 13, 1936, No. 4419. Convention date, Feb. 14, 1935. [Classes 20 (iii) and 20 (iv)] A partition, or interior covering structure for walls and ceilings, comprises an assembly of panels 21, as shown in Figs. 2, 3 and 5, and a supporting structure therefor, the edges of the panels being grooved to engage elongated paneledge supporting members 35 having interlooking tongue-and-groove connection with the supporting structure. The hollow partition shown in Figs. 2 and 3 comprises a supporting structure in the form of studs 38 composed of two pairs of angle-irons 40 welded to cross-ties 45, and the members 35, which are grooved as shown at 47, Fig. 3, for engaging the angle-irons 40, are in the form of T-shaped strips folded from sheet-metal so as to provide flanges 36 for engaging the grooves in the upper and lower edges of the panels. The vertical edges of the panels may be grooved to receive spline strips. The partition comprises base sections 22 which are grooved along the bottom edges for engaging the flanges 31 of a channel 30 secured to the floor. The panels 21, which may include a chair-rail section 23, are superposed on the base sections 22. At the top, the panels are engaged by a cornice member 50 comprising a flat plate 51 secured to the ceiling and downwardly-inclined portions 55 which are secured, adjustably, if desired, to the flat plate 51 and have upturned edges 56 for engaging the panels. The horizontal edges of the panels may have overlapping portions, which may be provided by rebating such edges. In a modification, each stud is in the form of two hollow strips 70 of T-cross-section, with outwardly-extended resilient flanges 73, as shown in Fig. 15 ; such strips are connected by ties 75 which have T-shaped ends 77 for engaging the interiors of the strips, and shoulders 78 for engaging the flanges 73. A tongue 79 bent upwardly from the tie also engages the interior of one of the strips 70 in order to stabilize the construction. The panels 21 are engaged by T-shaped strips 35<1> which have grooved ends 47 to receive the sides of the strips 70. For covering a wall, the horizontal edges of the panels are engaged by T-strips 35, as shown in Fig. 5, which have grooved ends 47 for engaging uprights 65 which are of T-cross-section and are folded from sheet-metal. The base sections, in this construction, may have a flange at the upper edge to provide a rebate for the reception of the superposed panels. In the ceiling construction shown in Fig. 8, the panels 21, which may be of mineral wool, or hard asbestos composition, are engaged by the T-strips 35<1> which are grooved at the ends for engaging the sides of hollow T-strips 70 adapted to be supported by flat T-shaped hangers 16 secured to the joists or other members. The edges of the panels need not be formed with grooves, but the flanges 36 of the T-strips 351 may be pressed into such edges during erection of the ceiling. In the modification shown in Fig. 12, similar ceiling-supporting hangers 16, 70 are used for carrying panels 121 in the form of sheet-metal or other pans adapted to contain soundinsulating material. The upturned flanges 135 of the panels are grooved at the ends, as at 147, for engaging the sides of the strips 70. Narrow end flanges 80 may also be provided on the panels. When a partition is built in line with a pillar 110 which is wider than the partition, the pillar may be enclosed as shown in Fig. 18 by interengaging hollow strips 70, together, if desired, with filling members 112. Specification 387,225 is referred to. The Specification as open to inspection under Sect. 91 describes also the following features. A wall construction employing built-up studs each in the form of a pair of oppositely-disposed channels 90 having skeleton bases as shown in Fig. 18 (Cancelled). Hollow T-section strips 70 are mounted in pairs on opposite sides of the studs by ties 95 having T-shaped ends 96 for engaging the interiors of the strips, and the panels 21 are secured to the strips 70 by screws 97 or other fasteners. Such a construction may be modified by inserting the panels between the body portions and flanges of the T-strips 70, and providing a plaster covering, and, if desired, the studs 90 may be dispensed with. The construction may also be modified by arranging for the flanges 91 of the studs to engage inside the T-strips 70 as shown in Fig. 21 (Cancelled), and for the panels 21 to engage between the body portion and flanges 73 of the strips. A covering 100 in the form of plaster units may be provided. A windowframe member 101 of hard asbestos or other material is applied to the end of a wall construction as shown in Fig. 21 (Cancelled), and a glass pane 105 is adapted to engage a resilient strip 106 provided in a hollow T-strip 103. The flanges 91 of the built-up stud shown in Fig. 28 (Cancelled) are adapted to engage interiors of the strips 70 and have offset portions 120 to prevent relative movement between the parts. The stud may also consist of two opposed T-strips 70 which are connected by a solid plate keyed to the strips 70 by cotters. The stud shown in Fig. 25 (Cancelled) is formed of two T-strips 70, each facing outwardly of the partition, and a T-headed tie 95 passes through apertures 117 in the body portions of the strips. This arrangement may be adapted for a ceiling construction, the tie 95 being secured to a joist and penetrating the base of a single T-strip 70 which faces downwardly ; a plaster covering is provided over the panels. In a wall covering construction, the panels 21 engage the T-strips 70 as shown in Fig. 26 (Cancelled), such strips being secured to a base wall by nails 88 which pass through a hollow member 85 disposed as a spacer between the member 70 and the base wall. A corner cornice is also described with bent portions to provide grooves for the reception of the wall and ceiling panels. This subject-matter does not appear in the Specification as accepted.
