Abstract: 523,833. Vehicle window frames; mouldings. THERMO-PLASTICS, Inc. Nov. 16, 1938, No. 33300. Convention date, April 12. [Classes 20 (iii) and 20 (iv)] A trim moulding for the window opening of a vehicle body comprises a peripherallyclosed member 1 of organic thermoplastic material having a decorative surface portion 3 facing outwardly with respect to the opening and also a decorative surface portion 2 lying substantially at rightangles to the plane of the opening. The " organic thermoplastic material" is defined as being distinct from thermal-setting phenolic resin materials, and exclusive of rubber; the preferred material is a cellulose organic acid ester, such as cellulose acetate. The portions 2, 3 are arranged to merge in a gradual curve. Extending outwardly from the portion 3 to a flange 6 which is integral with the number 1 and is disposed substantially co-extensive with, and parallel to, the portion 2, being spaced outwardly from the portion 2 and inwardly from the peripheral flange 7 of the portion 3. The flange 6 is interrupted by notches 8 which extend rearwardly from the portion 3 and open through the rear of the flange. Blocks 9 for attaching the moulding in a window opening are interposed between the flange 6 and portion 2 adjacent the notches 8, being arranged to bridge the space between the portion 2 and flange 6, and also to bridge across the rearward portion of the corresponding notches 8. These blocks, which may be formed of reconditioned thermally - mouldable material, have edge recesses to engage ribs on the flanges 6 adjacent the notches 8, and are cemented in place by acetone or other suitable cement. Reinforcing elements 12, Figs. 8 and 9, are secured between the rear margins of the flange 6 and wall portions 2, and have edge portions overlying the edges of these members. These elements may be of thermallymouldable material or metal and secured in place by acetone cement. If desired, the moulding may have a single peripherally - closed element 12. Sealing material adapted to contact the face of a vertically-slidable window panel is in the form of a fabric backing strip 15 with loose fibres 16 extending from the face thereof, such strip being either cemented to the elements 12 or secured thereto by shaping the elements so as to grip the edges of the strip. The moulding is secured in place by an L-shaped member 24, Fig. 9, at the lower edge of the window opening engaging behind the blocks 9, and at the upper edge of the opening spring tongues 26, Fig. 8, formed in the upper frame member engage the blocks 9. The lower portion of the moulding is formed with an integral decorative guard 20, Fig. 9, the edge of which bears firmly against the fabric lining of the vehicle. The moulding may, alternatively, be secured in place by screws which pass through the vehicle wall structure and enter the blocks 9. The modified moulding 41 shown in Fig. 12 is provided on its rear face with spaced projections 44 having notches 45 which are engaged by the edge of an angle member 47; the other edge of the angle member is seated on a shoulder 46 at the rear edge of the moulding. The angle member 47, which may Be of metal or thermoplastic material, is cemented in position and sealing material 49 is secured to its vertical face. The moulding shown in Fig. 15 is provided with a reinforcing element 50 which engages between the portion 2<SP>1</SP> and flange 6<SP>1</SP> of the moulding and has fixed to its outer face a sealing strip 51. The member 50 may be made of a material having a colour which contrasts with that of the portion 2' of the moulding. When the moulding is of cellulose acetate, it may be formed by the injection moulding process described in U.S.A. Specification 2,043,584. The Specification as open to inspection under Sect. 91 describes also the moulding as being formed of a number of sections which may be built up to form a peripherally-closed member. This subject - matter does not appear in the Specification as accepted.
