<p>648,667. Quilts. MINISTER OF SUPPLY. Nov. 16, 1948, No. 29836. [Class 142(iv)] [Also in Group VIII] Two layers of quilting A, B are formed by three sheets of cloth 1, 2, 3 between which are interposed layers of insulating material 4, 5. The lines of stitching 6 of one layer A lie substantially half-way between the lines of stitching 7 of the other layer of quilting B. Instead of layers of insulating material, three sheets of cloth stitched as before may have a loose filling of material introduced subsequently into the tubes or compartments formed when the stitching has taken place. The stitching lines may be straight and parallel or in a herringbone arrangement.</p> |
