LATHE, a very useful engine for the turning of wood, ivory, metals, and other materials. The invention of the lathe is very ancient. According to Diodorus Siculus, the first who used it was a grandson of Dædalus, named Talus. Pliny ascribes it to Theodore of Samos, and mentions one Thericles, who rendered himself famous by his dexterity in managing the lathe. With this instrument the ancients turned all kinds of vases, many of which they enriched with figures and ornaments in bas-relief. The Greek and Latin authors make frequent mention of the lathe; and Cicero calls the workmen who used it vascularii. It was a proverb amongst the ancients, to say a thing was formed in the lathe, in order to express its delicacy and justness. The lathe is composed of two wooden cheeks or sides, parallel to the horizon, having a groove or opening between, and perpendicular to these are two other pieces called puppets, made to slide between the cheeks, and to be fixed down at any point at pleasure. These have two points, between which the piece to be turned is sustained. The piece is turned round backwards and forwards by means of a string put round it, and fastened above to the end of a pliable pole, and underneath to a treadle or board moved with the foot. There is also a rest which bears up the tool, and keeps it steady. As it is the use and application of this instrument that forms the greatest part of the art of turning, we refer for the particular description of it, as well as
Lathreve the manner of applying it in various works, to that head. See TURNING.
Latimer. LATHREVE, LEIDGREVE, or TRITHENGREVE, was an officer under the Saxon government, who had authority over a third part of the county, and whose territory was therefore called trithing, otherwise a leid or leithin, in which manner the county of Kent is still divided. As to the jurisdiction of this officer, those matters which could not be determined in the hundred court were thence brought to the trithing, where all the principal men of the three or more hundreds being assembled by the lathreeve or trithinggreve, debated and decided it; or if they could not, then the lathreeve sent it up to the county court, to be there finally determined.
