    • n turnstile A post surmounted by four horizontal arms which move round as a person passes through; a turnpike. Turnstiles are usually placed on roads, bridges, or other places, either to prevent the passage of cattle, horses, vehicles, etc., but to admit that of persons, or to bar a passage until toll or passage-money is collected; they are also placed (sometimes with a turnstile-register) at the entrance of buildings, as where there is a charge for admission, or where it is desired to prevent the entrance of too many persons at one time.
