941,178. Boxes. H. G. KEWLEY. Oct. 20, 1959 [Oct. 21, 1958; Dec. 3, 1958; June 9, 1959], Nos. 33571/58, 38970/58 and 19708/59. Heading B8P. [Also in Divisions A4 and E2] A method of assembling a box using at least three strips of angle section which each have two webs with inwardly turned flanges at right angles to the webs, comprises arranging the strips in a plane, with the flanges of the strips engaging grooves or shoulders on the parts to be joined, and then simultaneously sliding the strips round the edges of the parts until the mitred ends of the strips engage and the parts are held firmly together. Fig. 6 indicates how strips 2A are slid together to form a picture frame, while Fig. 7 shows a section of the frame including a backing plate 30, a picture 32, and a glass plate 34. A similar construction can be applied to the top and bottom panels of a box, Fig. 4, the sides of the box being held together by similar strips 2 whose ends are squared. To prevent the strips 2A from sliding, notches 24 may be cut to accommodate the flanges of a strip 2. Described in the Provisional Specifications are a number of brackets which each have inturned flanges, and which are applicable to the manufacture of furniture, packing cases, cabinets and building structures. Specification 941,179 is referred to. |
