This invention relates to carriages upon which

levers to lift the carriage upon the wheels for
one point to another, it being especially adapted
for the purpose of raising the gun-mount from
the surface upon which it rests, supporting it
upon wheels for its travel, and lowering it to a
position in whichit may be secured for ?ring.
