              GATLING BATTERY. 
This implement of Warfare was invented and Patented by R.J. 
GATLING, of Indianapolis, Ind. Nov, 1862. 
IT IS CONSTURUCTED AS FOLLOWS: 
 
     Six heavy rifled barrels are strongly secured in a cylindrical form, to a solid breech piece of iron weighing nearly 100 pounds, which receives a shaft of he barrels on which the entire Gun revolves in an iron frame.  Each barrel has its own lock independent, inserted in the breach piece, on a parallel line of bore of the barrel, and revolves simultaneously with the barrel.  The breach piece with the locks are entirely encased with gun mettle, secure from dust or exposure. 
     Inside the casing a cam ring is inserted, and made stationary to the casing, and is the only machinery required to operate the locks. 
     Trunions are attached to the frame and rests on a heavy iron stand, and susceptible of any required degree of elevation or depression. 
     The stand is fitted to a plate below, which is made fast to the carriage, and by means of a king bolt 1¼ inches in diameter, the gun is connected to the lower plate and carriage and an instantaneous Lateral train motion is obtained, or by means of an eccentric with a screw attached to the lever on the stand (which is used for a quick Lateral motion,) the sight of the gun can be brought to the object as perfect as with a rifle, and held while any number of discharges take place. 
     The gunner can elevate or depress, and give a Lateral train motion if desired, while the gun is in operation. 
     Two hundred cast steel chargers, three inches in length, accompany each gun, for the reception of the cartridges of fixed ammunition, (sometimes called copper cartridges.)  The charges are placed in cases of 25 or more, and passed through a hopper, horizontally between the lock and barrel (until the explosion takes place,) by a forward motion of the lock, after which it instantaneously relieves part of the heat, and leaving the barrel open to receive a current of air through it from each succeeding discharge, until in the revolution it receives its next charge, thus obviating any heating of the barrels, to prevent the operation of the gun any length of time desired. 
     The locks are simple in construction, and weighing about 2½ pounds each, composed of three pieces only,  and in the motion required to perform their operation in holding the charger, is less than ¼ of an inch.  The hammer is one part of the lock, and one of the three pieces before enumerated, and is drawn back by the cam ring, and attached to the casing, and the force is given by a spiral spring. 
     All the lock hammers are moving on the cam ring at the same time, to off set on the sight line, which is about 1 inch. 
     There are no complicated parts about these Guns or Batteries, and nothing liable to get out of order by its own use.  These facts are derived by over 20,000 discharges of one gun or battery, and the exhibition of its operation without discharging over twenty times that number, (which is the same movement as when discharging,) and far more injuries to the working parts. 
     The rapidity of discharge is entirely under the control of the operator, and any number from one up to two hundred per minute, at a range of a mile to a mile and a quarter, with as much accuracy as with a rifle. 
     Five to eight men are only required to operate it, to its full capacity in action, and no infantry are required to support it, but will be found abundantly able to support itself, and a very effective support to infantry and heavy Batteries. 
     It has been universally admitted by many of the best Army and Navy officers in the government service, who have witnessed the operation of these Batteries, that it would be next to impossibility to make a charge on them, with any effect, when well manned.  But in case of a liability of capture, it can be totally disabled in less than one minute. 
     There is no recoil to the Gun; hence, the balls are discharged with great accuracy in an unlimited number, at one sighting, and perfect safety to the operators. 
     These Batteries can be used at long or short range, as experiments have convinced all who have witnessed the operation, established its capability and effectiveness against an advancing foe, or silencing Batteries within its range. 
     For field service, these Guns are mounted similar to light artillery, to be drawn by one or more horses.  The weight being about 1000 pounds, can be handled by men in action with great rapidity, when necessary.
