Fig. 1 shows the
portable rest manufactured by the Gardner Gun Company. It consists of
two wrought iron tubes, placed at right angles to each other; the front
bar can be easily unlocked, and placed in line with the trail bar, from
which project two arms, each provided with a screw that serves for the
lateral adjustment of the gun. These screws are so arranged as to allow
for an oscillating motion of the gun through any distance up to 15 deg.
The tripod mounting, used for naval as well as land purposes, is shown
in Fig. 2, which illustrates the two barrel gun complete. The five
barrel gun, Fig. 3, is shown mounted on a similar tripod. The length of
this weapon over all is 53.5 inches, the barrels (Henry system) are 33
inches long, with seven grooves of a uniform twist of one turn in 22
inches.
[Illustration: Fig. 2.--TWO BARREL GARDNER GUN.]
Gardener's five barrel gun in the course of one of the trials fired
16,754 rounds with only 24 jams, and in rapid firing reached a maximum
of 330 shots in 30 seconds.
