Abstract

245,535. Watt, J. A. D. Oct. 17. 1924. Moulding rotary hones &c.-A device for moulding hones having raised lands or tables of felt, leather, rubber, metal, &c. comprises a mould or container, means for positioning the lands and the spindle therein, and means for admitting plastic material thereto. Figs. 2 and 5 show one form of apparatus in which the mould 18 rests upon a shoulder 16<a> of a tubular member 16 carrying helical prongs 17 between which the lands 26b are positioned. The mould is closed by a cover 19 recessed at 19<a> to engage the prongs 17 and furnished with a boss 19b adapted to centre the spindle 21. Plastic material 27 is introduced through an aperture 20 in the cover and, during moulding, the lands may be pressed against the mould 18 by a helical spring. The moulded article is ejected by a plunger 23 operated by arms 24. Fig. 8 shows a modification in which the mould 30 is rifled and engages a rifled member 28, the lands being positioned between the riflings of the container. The mould is positioned for the moulding operation by a pin 32 engaging a recess 28<b> in the member 28, and is closed by a cover 33 having a boss 33a accommodating a member 34 for centering the spindle. The moulded article is ejected by withdrawing the pin 32 and depressing the mould. The described apparatus may be used to form hones composed of two or more plastic substances, e.g. a core of plastic material covered by a layer of plastic material impregnated with abrasive, either by casting the outer layer around a pre-formed core or by casting the outer layer around a sleeve inserted within the mould and, when set, withdrawing the sleeve and introducing the core material.
