W. H. Marley & Co. Ltd., 105 High Road, London, N.11, have introduced this 3 in. indexing attachment to speed up certain operations which would otherwise call for a more elaborate dividing head. The index plate provides 24 divisions, and the full circle can thus be divided into the factors 2, 3, 4, 6, 8, 12, and 24. Alternative plates can be supplied. The headstock can be fitted with a centre as shown in FIG 1 or with a chuck. The bases of headstock and tailstock are arranged for mounting on the tables of milling, drilling or grinding machines, or wherever else required.
