Sometimes badged as "Bridgeport" the Adcock & Shipley 1ES millers replaced the 1E range which had been introduced in 1964. The 1ES was build on the same foundation design as the 1E with heavily ribbed castings of great weight and stiffness. Fitted with a No. 40 INT nose, the spindle was supported in three bearings, two of which were of the high-precision, pre-loaded angular-contact type and mounted close behind the spindel nose.
A 2 hp motor was fitted across the range and enclosed, with all the ancillary electrical equipment, inside the machine base.  In comparison with the 1E the makers claimed a knee of improved stiffness with some 50% increase in the width of the knee bearing on the column together with a better locking system. Wider; an improvement of 30% in table area and a 30% increase in table travel.
The range was divided into the "M" machines, which featured purely hand-feed tables, the "G" and "J" models for repetitive production work with
Mechanical Auto Feed and Auto-cycle Mechanisms and the "AH" type - the latter fitted with an Auto-cycle system driven by Air-Hydraulic power.
Intended for general-purpose work the "standard" machine was the Model 1ES-G that had 18 spindle speeds from 50 to 2500 rpm and 6 rates of longitudinal table feed from 0.004" to 0.50".

18 spindle speeds from 50 to 2500 rpm and 6 rates of longitudinal table feed from 0.004" to 0.50"

Another model sometimes found carrying the Bridgeport badge, the Adcock & Shipley Model 1ES-AH was designed for very fast auto-cycle work where a fast cycle time was more important than a heavy cut. Twin air cylinders, connected to a compressed air supply, provided a rapid traverse of 400"/minute with a hydraulic cylinder to control the feed when under cut.
The rate of feed was infinitely variable between 0.25" and 120" per minute and the twelve spindle speeds varied between 250 and 2500 rpm.
So that the operator could not trip the cycle into action accidentally, both hands on the controls were needed to initiate it.

Adcock & Shipley Model 1ES-M designed for types of work where manual hand feeds were better employed. A lever feed was provided to the table, and screw feed to the cross traverse and knee. 

Adcock & Shipley Model 1ES-J. This model was an automatic cycle machine, but designed for ease of setting up and therefore ideal for small-batch production runs.
A single lever initiated the cycle of rapid approach, change to feed cut and then rapid return. The rapid approach and return speeds were 220" per minute and the twelve cutting-feed rates varied between 0.005" and 0.044" per single revolution of the cutter spindle.
As on the ordinary 1ESG, eighteen spindle speeds were provided from 50 to 2500 rpm.
