The Refinement of the Ornamental Lathe
by Holtzapffel
Generally considered in the same breath with the term "ornamental turning" is the family name of Holtzapffel. John Jacob Holtzapffel
moved from Alsace to England in about 1785 and opened his engineer's tool business in London in 1793. His first lathe was sold to a
Mr. Crisp on June 31st 1795, the outfit costing £ 25-4s-10d. When one considers that today this would be over £ 2000, or $3000US, and
that the skilled mechanic of the day earned less than 8d per hour, this lathe represented over 3 months wages. All of Holtzapffel's lathes
were numbered, and not all had full ornamental turning apparatus included. By about 1805, after the Holtzapffel firm had reached nearly
No. 500 in their numbering scheme, almost all lathes had iron beds instead of the previously used mahogany wood beds. The last
lathe sold was Holtz. No 2557, made in 1913/14 and sold in Nov. 1928. No other maker of ornamental lathes matched the productivity of
the Holtzapffel family in the field of ornamental lathes.

When John Jacob I died in 1835, about 1600 lathes had been sold by his firm. Not all were fully equipped as ornamental lathes, but with
the large number that were, quite an impetus was given to ornamental turning as a leisure occupation in England. The introduction of
the cutting frame by Holtzapffel allowed for significantly more complex patterns to be cut as compared to what could be done previously
with only the drilling frame. The elder Holtzapffel standardized his screw threads before 1800, his spindle thread being 9.45 threads per
inch for example, and the firm maintained this standard throughout all the lathes they manufactured. This standardization was initiated
long before any kind of screw standards were established for industry at large.

The son of John Jacob I, Charles, who joined the firm in 1827, began the monumental series of five books that were called Turning and
Mechanical Manipulation in 1835. This ambitious effort, comprising over 3000 pages and 1600-odd illustrations, was intended to be a
complete survey and overview of all the mechanical arts of the day. It was not until 1884 that Vol. V was published by the son of Charles
Holtzapffel, John Jacob II. However, it was not until 1894, with the addition of a revised and enlarged version of Vol. III, that the set was
complete. Today, Vol's. IV and V of this series are known as the "Bible of Ornamental Turning" because of their wealth of information
about all aspects of the craft of ornamental turning. Charles managed the firm until his death in 1847. He was considered a
distinguished engineer, developing and inventing various devices. An obituary notice remarked of him that,

Mr. Holtzapffel probably never put his hand to a machine which he did not improve, and his practice in the construction of machines has
been more miscellaneous probably than that of any other mechanist, his workmanship more accurate, and his general mechanical
arrangements more refined...He had all the humility of genius without its eccentricities, and his heart habitually overflowed with
kindness towarrd everyone around him.

Charles' wife, Amelia, ran the firm until 1853, and in 1867, Charles' son, John Jacob II, became head of the firm until 1896. He died in
1897. A nephew of Charles, George William Budd, became head of the firm in 1896. Few ornamental lathes were made after the turn of
the century and the 19th century was known as the zenith of the ornamental turning lathe. Many lathes were sold to the aristocracy of
England. The earl of Harborough, for instance, bought nine Holtzapffel lathes between 1812 and 1848. This was certainly not common,
but is instructive of the popularity of these machines once one developed an affinity for OT.

The contribution of John Jacob Holtzapffel's work was significant in several respects. As expressed by Walshaw (see Bibliography),
"First, he brought the cost of the machine down to a figure which a mere 'gentleman' (or even a prosperous tradesman) could afford,
and, second, the design was both elegant and functional." His designs were much improved over the lathes previously made on the
continent of Europe. Holtzapffel also was a master of marketing apparatus to his clients over time. Improvements and additions to
apparatus increased the capability of his equipment and induced his clients to continue to be his customers. The remarkable set of
books by the family were, in effect, an extensive set of owner's manuals for their machines.
