Abstract: 11,656. Richards, F. H. June 10, A.D. 1902, [date applied for under Patents Act, A.D. 1901]. Moulding balls.-Relates to a golf ball having a core 1 of soft india-rubber or other suitable material and a compressed shell of plastic material, usually gutta-percha or celluloid. The shell is cast in one piece and holds the core under compression. The core 1 is suspended centrally in a spherical mould consisting of two sections 2, 3, by means of four needles as 7, 7<a> arranged in opposite pairs. The needles pass through bearing-holes in the lower section 2 and are fixed to slides 13, 13<a> mounted in ears 15 formed on standards 16 and capable of horizontal movement towards and away from the centre of the mould. The needles are operated by arms 17 pivoted at 19 and rigidly fixed to levers 22 connected by drop links 23 to a slider 24, which is mounted on a vertical stem 26 and driven upwards by a lever 27 pivoted at 28 and carrying a handle 30. A spring 31 acts on the slider 24 in a direction to press the needles towards the centre of the core. The mould-sections are clamped together by wing-nuts 33, working on vertical rods 34 pivoted to lugs 35 on section 2. These nuts bear on ears 36 on section 3, which are slotted so that the clamping-rods may be thrown off. The shell material is contained in a cylinder 37 and kept hot and fluid by a gas burner 41. The fluid material is forced through a pipe 39 into the mould at 40, the pressure, which is applied by a piston 42, being maintained during the cooling, so as to feed material to the mould as the ball shrinks. Before casting the shell, the mould may be heated by passing hot water or steam through passages 47, 48, and air is exhausted from the mould by a pump 44 connected thereto by a valve 46. When the mould is filled with the plastic material, the valve 46 is closed and the whole ball is submitted to great pressure by the piston, cold water being circulated through the channels 47,48. When the shell has cooled sufficiently to hold the core under compression, the needles are withdrawn, the upper section of the mould removed, and the ball taken out ; the holes left by the needles may be plugged if desired. The moulds are provided with pits 5 for embossing the ball.
