The making of axles as a specialized trade began in the 18th century, but the first North American makers of whom we have any record came somewhat later. Frederick Ive’s Mount Carmel Axle Works of New Haven, established in 1833, was one of the first in the field, and like most others in those days, his factory also produced springs and other hardware. By the 1870s there were several large factories making axles only, and one of the leaders was the Dalzell Axle Company of South Egremont. The founding genius of this company was David Dalzell, born in Scotland in 1811 and brought to America by his mother at an early age.
After leaving school Dalzell became an apprentice carriage trimmer with the firm of Robinson & Vanderbilt of Albany, New York. In 1831 he contracted with James Goold to trim the first six railway coaches constructed in America, and soon afterwards he started his own carriage business in Hudson, New York. In 1845 David Dalzell moved his carriage factory to South Egremont, located in the western part of Massachusetts not far from the famous Salisbury iron mines. Pittsfield, some twenty miles to the north, was already something of a factory center, making use of the local iron supply, and it was from there that Dalzell obtained his axles in the early days. Itinerant tradesmen were not uncommon in those parts then, and one day a rather seedy looking individual presented himself at the Dalzell shop seeking work, claiming to be skilled as a wheelwright and carriage smith, as well as being familiar with most other trades connected with carriage building. He was set to work building a stock of wheels, and when this was accomplished he offered to make axles too if he could be furnished with a lathe. This done, our stranger of many skills made for himself the taps, reamers and other necessary tools for axle making. His products turned out to be far superior to the axles Dalzell had been using up until then. Not surprisingly it was not long before other carriage makers were wanting them also, and, realizing that fate had given him the opportunity of producing something for which there was a keen demand and little competition, Dalzell decided to specialize in axle making.
A large factory building was put up and equipped with the best power lathes and other machinery for turning out axles that Dalzell determined would be better than any others on the market. How well he succeeded is shown by the list of customers he soon had, among them the leading builders of the day such as James Hall and Thomas Goddard of Boston, Jason Clapp of Pittsfield, Long & Silsby and James Goold of Albany, John R. Lawrence, Bradley & Pardee, Brewster & Baldwin, Wood Brothers of New York and William D. Rogers of Philadelphia. Dalzell introduced a method of forging his axles and collars from the solid bar instead of using welded collars. Other makers had tried forging the collars by the process known as "upsetting," that is, by making a swell in the metal at the desired place by means of heat and end pressure; the Dalzell method was to start with metal of the required diameter for the collar and then to draw out the axles arms or spindles by forging. He also adopted the case-hardening process which rendered the arms less susceptible to wear, and he overcame the tendency to fracture that other users of this technique had experienced.
