Time recorder

A time clock, sometimes known as a clock card machine or punch clock or time recorder, is a mechanical (or electronic) timepiece used to assist in tracking the hours worked by an employee of a company.

In mechanical time clocks this was accomplished by inserting a heavy paper , 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 (a timestamp) on the card.

One or more time cards could serve as a timesheet or provide the data to fill one. This allowed a timekeeper to have an official record of the hours an employee worked to calculate the pay owed an employee.

The terms Bundy clock, bundy clock, or just bundy have been used in Australian English for time clocks. The term comes from brothers Willard and Harlow Bundy.

An early and influential time clock, sometimes described as the first, was invented on November 20, 1888, by Willard Le Grand Bundy, a jeweler in Auburn, New York. His patent of 1890 speaks of mechanical time recorders for workers in terms that suggest that earlier recorders already existed, but Bundy's had various improvements; for example, each worker had his own key. A year later his brother, Harlow Bundy, organized the Bundy Manufacturing Company, and began mass-producing time clocks.

In 1900, the time recording business of Bundy Manufacturing, along with two other time equipment businesses, was consolidated into the International Time Recording Company (ITR).

In 1911, ITR, Bundy Mfg., and two other companies were amalgamated (via stock acquisition), forming a fifth company, Computing-Tabulating-Recording Company (CTR), which would later change its name to IBM.

The Bundy Clock (see image left) was used by Birmingham City Transport to ensure that bus drivers did not depart from outlying termini before the due time; now preserved at Walsall Arboretum.
