- accumulator plate maker
- see caster, plate.
- aluminium founder
- see caster, aluminium.
- as for caster (183) except that usually casting is done by pouring from hand ladles, dipped into larger ladles, as non-ferrous castings are generally small; also moulds are usually made of metal except where unusual shapes or sizes of eastings are required; sometimes specifically designated, e.g., lead caster.
- caster, aluminium; aluminium ingot caster, ingot caster (aluminium)
; aluminium, founder
- a caster q.v. who pours molten aluminium from ladle or crucible, usually by band, into moulds (either sand or metal moulds), or into iron ingot moulds, for casting aluminium articles or ingots; cf. die caster (278).
- caster, grid
- see castor, plate.
- caster, needle; hosiery needle caster
; hosiery needle, moulder
- sets bearded hosiery needles in mould and pours molten lead from band ladle into mould, so that when cool, one end of needle is fixed in bed of lead; removes iron moulds and takes out needles.
- caster, plate; lead plate caster
; accumulator plate maker, grid caster
- a lead caster q.v. who pours molten lead from hand ladle into iron moulds to form plates or grids for accumulators, fills hand ladle, as required, by dipping in iron tank of molten lead; maintains fire or gas under container or tank at proper beat.
- caster, shot
; shot maker
- runs, by means of pipe from iron crucible or ladle, molten alloy of lead and arsenic over a wire sieve set at an angle, so that lead falls through sieve about 100 feet down into tank of water, assuming spherical shape in falling: shovels out lead shot formed, into machine which sorts them into sizes.
- caster, tea lead
- (i) a caster q.v. who casts lead into strip ingots for rolling in thin lead sheet for packing tea:
- (ii) (older method) pours molten lead into gutter, at top of sloping table, till gutter is filled and lead overflows and runs down table into gutter at bottom; when table is covered with thin film of lead, strips lead sheet from table and, if necessary, passes it to be rolled.
- furnace man, aluminium foundry
- places aluminium ingots into plumbago or iron crucibles and places crucibles, by means of tongs, into sunken furnace, either gas or coke fired; regulates temperature of furnace by opening or closing valve admitting gas to burners or by regulating supply of coke; watches pyrometer dial to ensure that temperature of furnace is kept at just above melting point of aluminium; when molten, stirs aluminium scrap and chips into crucible with a steel bar and throws on flux (crystals of zinc chloride, or cryolite) to prevent oxidation of metal on surface; withdraws crucible when ready and places it on a chair for conveyance by hand to caster q.v.
- furnaceman (load shot)
- places pig lead and scrap lead in iron crucibles set in furnace and tends to heating of crucible and contents; when lend is molten, shovels in arsenic to form alloy; stirs it in with iron rod; inserts iron pipe under surface of lead and turns on tap running lead on to sloping wire grid, through which it falls into tank of water below assuming spherical form in falling; replenishes crucible with pig and scrap lead and arsenic at intervals.
- moulder, hosiery needle
- see caster, needle.
- shot maker
- see caster, shot.
