Tyntesfield, North Somerset
NT 39949.1
Summary
An iron boring collar, consisting of a circular iron plate with a series of conical holes, equidistant from a central nut, bolt and washer. It is carried by the bolt on an iron head, (NT39947.2.1) having a tenon fitting between the bearers of the lathe bed, secured beneath them by means of a bow-nut (NT39947.2.2). The collar plate turns on its center to place any hole vertical, and opposite the axis of the mandrel; in which position it is fixed by the screw and nut upon the pivot. The large ends of the holes are placed towards the mandrel, and the series serves for works of all diameters that are between their extremes. Associated with Holtzapffel lathe (NT39554).
Provenance
Purchased from John Edwards in 2017, and brought back to Tyntesfield thanks to a generous anonymous donation. Antony Gibbs (1841-1907) purchased this lathe, grinding machine and the accompanying suite of accessories from Holtzapffel & Co in 1872. It was sold originally in 1852 to Count Dunin for £137.16.0. It was later returned to Holtzapffel & CO., refurbished and sold to Sir A Sterling in 1861. It was again returned to Holtzapffel, completely refurbished and resold in 1872 to Antony Gibbs Esq of Tyntesfield, Bristol for the sum of £220. On Antony’s death the lathe passed to his son Antony Hubert Gibbs of Clyst St George. In 1953 it was sold at an auction of the Gibbs estate and subsequently ended up in Scotland where it languished for the next 60 years, until it was acquired by John Edwards, an ornamental turner, who cleaned and overhauled it.
