Synopsis
Excerpt from Pattern-Making Machinery: Manufactured by Richards, London Kelley, Atlantic Works, Philadelphia
Designs were prepared without any reference to the precedents furnished by other builders. The proportions and fitting were based upon the functions of the machines alone; the framing, gearing, shafts, bolts, belts and other details were adapted to the strains, and the conditions of their operation, so far as a long experience could determine. All ingenious complications were avoided, no small screws, springs or other details known as traps, were used. Screws were all turned, the heads and threads made to conform to a regular system; bored and turned fits were made to standard sizes, and wearing surfaces scraped to a perfect bearing. Spindles were made of steel, with bearings of brass. Wheels and pulleys were fastened with steel keys instead of set screws. Details that were subject to wear were case - hardened instead of polished.
The success that has attended the business and the machines during the five years past, has proved that the merits of good fitting and careful designs and proportions, are fully appreciated by those who have purchased them.
The pattern machines, although lighter, and much. Less expensive than car builders machines; will be fitted with all possible care, and it is trusted will find favor and approval from the numerous establishments interested in machines of this class.
