Description of Lathes

A brief history of the periods of production:

  • From 1795 to 1803, under the direction of founder John Jacob Holtzapffel I, the firm produced and sold 385 lathes, including Holtzapffel's first rose engine lathe in 1797.
  • From 1804 to 1827, a partnership with assistant John George Deyerlein was formed. Business was conducted under the name Holtzapffel & Deyerlein, and the lathes themselves began to be numbered. During this period, the company manufactured nearly 1000 lathes.
  • In 1827, Deyerlein left the firm and John Jacob's son Charles joined the business. Nine years later, when his father died, Charles headed the business until 1847, the time of his early death. During this period, the firm produced approximately 400 new lathes.
  • At the time of his father's death, John Jacob II was still a minor. Therefore, Charles' widow Amelia ran the Holtzapffel firm until 1853, during which approximately 65 lathes were manufactured.
  • John Jacob II ran the firm until 1896, during which time the firm produced approximately 400 new lathes.
  • From 1896 until 1928, when the business closed its doors, they manufactured and sold the remaining 100+ lathes.

In addition, it was common for lathes to be returned to the factory for augmentation, refurberation, and resale. The above tallies do not include that additional production.

Catalog Description of Lathes

A Holtzapffel trade catalog, published sometime between 1906 and 1928, contains descriptions for eighteen distinct lathes for purchase. A note encourages potential buyers that any of the lathes may be customized with more or less apparatus and in any way desired.

Complete Lathes – Descriptions One to Eighteen

The greater number of the Lathes, descriptions one to eighteen, are specified as of five-inch centre, and these have bearers 3 feet 3 inches long. Lathes of this size are recommended for amateur and workshop use, as being most generally convenient, as they are sufficiently large for the largest pieces of ivory and hardwood commonly met with, and to allow a proportionate degree of strength in the numerous additional apparatus, without being unwieldy or inconvenient from excessive friction in their moving parts. The bearers of Lathes of 4-inch height of centre are usually 2 feet 10 inches long, 5-inch centre are 3 feet 3 inches long, and those of Lathes of 6 or 7 inches are from 4 to 7 feet in length as may be required. The frames may be as specified, or they may be of wood or iron as desired.

For occasional purposes, the range of the 5-inch Lathe may be increased by using lifting pieces or raising blocks, and in length by lengthening bearers, or bearers of any length will be provided.

In selecting turning apparatus, many amateurs prefer to begin with a small outfit, and gradually to extend it by successive additions. Much of the apparatus is constructed with the object of facilitating this, and most of the Lathes may be thus advanced to the condition of those higher up in the scale of completeness. for example, it will be seen by examining the following descriptions that the Lathe Description Five (£38) may be converted into the most complete of those with beechwood frames, and the Lathe Description Ten (£75) may be rendered, by additions, equal or superior to the Lathe Description Eighteen, the most elaborate of those specified.

Any of the Lathes in the following list will be modified in any way that may be desired, by the addition, omission, or exchange of apparatus, the descriptions and particulars of which are more fully described in the subsequent pages on detached Lathe apparatus.
