A typewriter is a mechanical or electromechanical device with a set of "keys" that, when pressed, cause characters to be printed on a medium, usually paper. From their invention before 1870 through much of the 20th century, typewriters were indispensable tools for many professional writers and in business offices. By the end of the 1980s, word processor applications on personal computers had largely replaced the tasks previously accomplished with typewriters. Typewriters, however, remain popular in the developing world and among some niche markets, and for some office tasks.

By about 1910, the mechanical typewriter had reached a somewhat standardized design. There were minor variations from one manufacturer to another, but most type writers followed the concept that each key was attached to a type bar that had the corresponding letter molded, in reverse, into its striking head. To have letters typed in exact location, the type bar was guided all its way till the ribbon by segment. When a key was struck briskly and firmly, the type bar hit a ribbon stretched in front of a cylindrical platen that moved back and forth. The paper was rolled around by the type writers platen, which was then rotated by the carriage return lever into position for each new line of text.

Ironing is the work of using a heated tool, or tools, (an iron) to remove wrinkles from fabric. The heating is commonly done to a temperature of 100° Celsius. Ironing works by loosening the bonds between the long-chain polymer molecules in the fibers of the material. While the molecules are hot, the fibers are straightened by the weight of the iron, and they hold their new shape as they cool. Some fabrics, such as cotton, require the addition of water to loosen the intermolecular bonds. Many modern fabrics are advertised as needing little or no ironing. Permanent press clothing was developed to reduce the ironing necessary by combining wrinkle-resistant polyester with cotton.

A time clock, sometimes known as a clock card machine or punch clock or time recorder, is a mechanical timepiece used to assist in tracking the hours an employee of a company worked. In regards to mechanical time clocks this was accomplished by inserting a heavy paper card, called a time card, into a slot on the time clock. When the time card hit a contact at the rear of the slot, the machine would print day and time information on the card. This allowed a timekeeper to have an official record of the hours an employee worked to calculate and pay an employee.
