The first management development class is held for factory managers.
1922
The Endicott Engineering Laboratory develops a Type 1 printer increased to seven printing banks. The lab also improves the sorter with the addition of a single column selector.
The Endicott Engineering Laboratory develops an electric key punch, and improves the printing tabulator (changing its design to Type 2).
Fred M. Carroll, a company engineer at Endicott, invents the Rotary Card Press (Carroll Press), a continuous process press for the production of punched cards.
Endicott employs 975 people.
The production of punched cards in CTR's plant the Georgetown section of Washington, D.C., cannot keep up with demand, and the company decides to begin card manufacturing in Endicott.
1924
The Endicott Engineering Laboratory changes the seven bank machine so that the extra printing banks can print group indication numbers when the machine is operating as a non-lister. The lab also improves the Type 3 machine for progressive total printing and split automatic control.
The Endicott Engineering Laboratory develops a horizontal sorter and duplicating key punch.
Fred Carroll develops a rotary card manufacturing machine which, when placed into production, increases the output of punched cards from 30 to 400 cards a minute. (By 1936, improved versions of the rotary were producing 650 cards a minute, and by 1938, 800 a minute, and by 1960, more than triple the rate of the 1925 version.)
1926
The Endicott Engineering Laboratory develops an automatic gang punch, and adds a quick insert device to the carriage.
Endicott employs 1,100 people.
C. D. Lake serves as the works manager.
1927
The Endicott Engineering Laboratory develops major, intermediate and minor control.
March 16 -- The International Time Recording Company purchases additional property.
A formal program of sales and service instruction is inaugurated in a room of the manufacturing headquarters. There are 140 students in that class.
Endicott employs 1,100 people.
1928
The Endicott Engineering Laboratory develops 80-column equipment, the Type 4 six-counter machine, class selector, a small set of machines consisting of a vertical non-printing accounting machine and a vertical sorter (for small businesses), and a printing card counting sorter.
The first IBM suggestion awards are presented when 29 employees are presented 36 awards for a total of $123.50.
The Endicott Engineering Laboratory develops a numbering gang punch, numeric interpreter, a reproducer that changes 45-column cards to 80-column cards, an electric key punch and duplicator with automatic feed and ejection device, and accounting machines improved to add twelfths.
The International Time Recording Company purchases additional property on February 9, February 14 and May 27.
The Endicott Engineering Laboratory develops an electric key punch, and improves the printing tabulator (changing its design to Type 2).
The Endicott Engineering Laboratory develops major, intermediate and minor control.
