Summation Chain

The summation chain runs around pulleys on Tide Predicting Machine No. 2, a special purpose mechanical analog computer for predicting the height and time of high and low tides. The pulleys move up and down and the chain sums their displacements to compute the height or time of high and low tides. The U.S. government used Tide Predicting Machine No. 2 from 1910 to 1965 to predict tides for ports around the world. The machine, also known as “Old Brass Brains,” uses an intricate arrangement of gears, pulleys, chains, slides, and other mechanical components to perform the computations. A person using the machine would require 2-3 days to compute a year’s tides at one location. A person performing the same calculations by hand would require hundreds of days to perform the work. The machine is 10.8 feet (3.3 m) long, 6.2 feet (1.9 m) high, and 2.0 feet (0.61 m) wide and weighs approximately 2,500 pounds (1134 kg). The operator powers the machine with a hand crank.

NOAA's Tide Predicting Machine No. 2

This photo shows the largest of the three sections of Tide Predicting Machine No. 2, a special purpose mechanical analog computer for predicting the height and time of high and low tides. The gears on the left transmit power from the hand crank. The components on the right contribute to the computation of the time of high and low tides.

Summation Chain Close-Up

A part of the summation chain of Tide Predicting Machine No. 2, a special purpose mechanical analog computer for predicting the height and time of high and low tides. By wrapping above and below a series of pulleys, the chain sums their deflections, which is a key component of computing tides. The U.S. government used Tide Predicting Machine No. 2 from 1910 to 1965 to predict tides for ports around the world. The machine, also known as “Old Brass Brains,” uses an intricate arrangement of gears, pulleys, chains, slides, and other mechanical components to perform the computations.

Tide Formula Component Cranks on Tide Predicting Machine No. 2

Tide formula component cranks on Tide Predicting Machine No. 2, a special purpose mechanical analog computer for predicting the height and time of high and low tides. The mechanical arrangement (a slotted crank yoke) converts circular motion to a sinusoidal motion. The operator adjusts the position of the pin on each crank to represent the tide formula at a specific port before starting computations. The pin position affects the amplitude and phase of the sinusoid. The U.S. government used Tide Predicting Machine No. 2 from 1910 to 1965 to predict tides for ports around the world. The machine, also known as “Old Brass Brains,” uses an intricate arrangement of gears, pulleys, chains, slides, and other mechanical components to perform the computations.
