Pintle

In artillery, is the vertical bolt around which the cha is is traversed. In the centre-pintle carriage it is the centre of the cha is, but in the front-pintle carriage it is in the centre of the front transom. It is a stout cylinder of wrought iron inserted in a block of stone, if the battery be a fixed one; or it is secured to cro -pieces of timber bolted to a platform firmly imbedded in the ground, if it be of a temporary nature. In casemate batteries the pintle is placed immediately under the throat of the embrasure, and the cha is is connected with it by a stout strap of iron, called the tongue.
