Emergency Tension Weight Used on Typewriter
If the band that draws the typewriter carriage should break, the operator can continue to write until proper repairs are made by a temporary substitute for the spring tension. Tie a string to the carriage, where it will not become entangled in the mechanism, and attach a weight, about equal to the pull of the spring, to the string. Let the weight hang over the edge of the desk, to the left of the machine. It will pull the carriage along, as does the usual tension device.
