- Boucheuse /lance de gunitage
- The usual service name for a cannon (which see); it was originally called great gun, to distinguish it from the small or hand guns, muskets, blunderbusses, &c. the general construction for guns of cast metal is fairly represented by the old rule that the circumference at the breech ought to measure eleven calibres, at the trunnions nine, and at the muzzle seven, for iron; and in each instance two calibres less for brass guns. but the introduction of wrought-iron guns, built up with outer jackets of metal shrunk on one above another, is developing other names and proportions in the new artillery. (see built-up guns.) the weight of these latter, though differently disposed, and required not so much for strength as for modifying the recoil or shock to the carriage on discharge, is not very much less, proportionally, for heavy guns of full power, than that of the old ones, being about 1-1/4 cwt. of gun for every 1 lb. of shot; for light guns for field purposes it is about 3/4 cwt. for every 1 lb. of shot. guns are generally designated from the weight of the shot they discharge, though some few natures, introduced principally for firing shells, were distinguished by the diameter of their bore in inches; with the larger guns of the new system, in addition to this diameter, the weight in tons is also specified.—gun, in north-country cant, meant a large flagon of ale, and son of a gun was a jovial toper: the term, owed its derivation to lads born under the breast of the lower-deck guns in olden times, when women were allowed to accompany their husbands. even in 1820 the best petty officers were allowed this indulgence, about one to every hundred men. gunners also, who superintended the youngsters, took their wives, and many living admirals can revert to kindness experienced from them. these “sons of a gun” were tars, and no mistake.—morning gun, a signal fired by an admiral or commodore at day-break every morning for the drums or bugles to sound the reveille. a gun of like name and nature is generally in use in fortresses; as is also the evening gun, fired by an admiral or commodore at 9 p.m. in summer, and 8 p.m. in winter, every night, on which the drums or bugles sound the retreat.
- [1] a generic term for the carriage-mounted cannon of sailing warships. [2] any piece of ordnance from which missiles are propelled by explosion through a metallic tube.

Gun carriage, английский
[1] generically, any structure on which a gun is mounted and fired, whether wheeled or not. [2] specifically, a 4-wheeled wooden framework on which a sailing warship’s cannon was mounted. the first carriages for ship’s cannon sat upon two large cart-wheels, like the guns used on land. but, by the mid–1500s, the english had developed the “truck carriage” which had four small solid wooden wheels, one on each corner. compared to the earlier two-wheeled design, weight was more evenly distributed, it could be rolled right up to the gunport, and was easier to train left or right using a lever known as a “trailspike.” at first the carriages had solid flat beds, but by about 1700 most were fabricated from two thick side pieces known as “cheeks,” linked by stout baulks of timber known as “transoms” or “axle-trees,” with metal reinforcing bolts to hold the parts together. the cheeks were stepped from front to back, providing points of purchase when the gunners were elevating the barrel of the gun using trailspikes. this design became the standard form of maritime gun carriage throughout the muzzle-loading era, except for the spanish armada which used two-wheeled sea carriages until the early 17th century.
Gun consistency, английский
