Abstract

671,813. Moulding sash weights. DIAMOND, P. J. Aug. 4, 1950 [Oct. 5, 1949], No. 19574/50. Class 87 (ii) [Also in Group X]' Sash weights are made by tightly packing fragments 4 of scrap iron or steel around a rod 1 in a cylindrical mould 7 and filling the spaces 5 with a thin cement slurry. The mould 7, preferably having an internal diameter not greater than 1# inch may be made in two parts, or it may be made as a thin metal tube, in which case it forms a permanent outer covering for the weight. Small amounts of lead and cast-iron borings may be included in the weight. To ensure that all of the spaces 5 are filled, small amounts of packing and slurry are added alternately until the mould 7 is filled. A rod 1 is provided with an eye 2, and is either bent at its other end as at 3 or has a washer riveted to it.
