Tho preceding figure represents held-gun
mounted, when limbcred up and the locking shoe
adjusted az prepared to descend a hill.
The stock is made in the form represented and at
tachsd TO tho under side Of the axle by Of the
bolts connected with n strong saddle resting on the
top Of the axle, M shown in the figure. by this
mesus ON enabled to give greater degree OF ele-
walton TO the piece, and at tho samc time, maintain
tho proper strength in the carriage TO sustain the re-
coil when fired at such high elevation, and the car
riages Of q battery thus constructed occupy but
about two-tbrds Of the space occupied by The CON-
mon United States carriage, when packed Tor trans
portaton on ships. 1t gives room, also, to
fix sponge and rnmmer AS seen in tho Figure. on
the top Of the trail where they are not exposed TO
being torn of or broken, as IL below the trail The
cheeks embrace the upper portion Of axle, and are
bolted to the stock or upper end OF the trail. They
are aso connected by rondello in front OF the axle.
The form Of the cheeks are peculiar, presenting no
SALEM angles, and 30 rounded as TO each receive
strap extending entirely around !. and the axle. By
means of nut arranged represented, and aided
BY DO Il and corresponding nuts, this strap may be
taken up, a. the wood Of which il is composed
shrnls, and may be caused to maintain tight con-
dition upon the checks at oil times
In my carriage the elevating screw mover projects
below the trail TO strike an obstruction.
In gun carriages, as ordinarily constructed, the
violent recoil Of the gun tends TO twist of tho fasleu'
ing. which are all Oh the top Of the axle by which
tho axle is secured In this construction there 10 no
such tendency.
The trail is Of the usual form, except where it
rests upon the ground The ordinary trail rounded
at this latter point 30 as 10 form portion OF
cylinder with the axis at right angles TO the plano
of the trail. Such form allowed only small sur.
face Of the trail to rest upon the ground, aud the
pressure thereon at the instant Of recoil was great
as to cause it to dig into the ground and partially
bury Itself therein. While this action diminished
the amount of tho rccoi and was go far an advaut-
age, it 10 altered the condition OF the ground on
which it rested and moved, that another shot could
not DO fired from the same position, without read
justment Of the elevation Of the gan and also OF the
trail, which would sometimes slip, after ths gun
was carefully sighted. In my carriage form plane
surface under the TRAIL where it re's upon the ground
which surface 10 gradually rounded into the inclined
surface Of tho trail, ~ shown. This plane portion
presents 90 broad surface to the gound on which
1t rests, ~ TO prevent the trail from digging hole,
and 10 avoid the consequent necessity OF "a frequent
change in the position of the carriage, ora correspond
ing change in the elevation of tho gun, relatively tothe
carriage. This feature is Of great Importance in
carriages constructed TO admit of 90 great AL elevs
ss mine for the strain the carriage 10 greatly In
creased at such elevations, and would be liable to
break II, unless it were vt liberty to recol freely
And II tho trail was 90 pressed in the earth as TO
seriously rstsrd tho rec0i tho liability Of damage to
