IMPROVEMENTS IN GUN CARRIAGES
Year: 1880

Prussia and Empire of Germany, Engineer and Patent Solicitor, for an
Invention of "IMPROVEMENTS IN GUN CARRIAGES." A communication by
Otto Krell, of St. Petersburg, in the Russian Empire.
PROVISIONAL SPECIFICATION left by the said Friedrich Carl Glaser at
the Office of the Commissioners of Patents on the 15th December 1880.
FRIEDRICH CARL GLASER, of Berlin, in the Kingdom of Prussia and Empire
of Germany, Engineer and Patent Solicitor. "IMPROVEMENTS IN GUN
CARRIAGES." [A communication by Otto Krell, of St. Petersburg, in the Russian
Empire.]
The said improvements in gun carriages will be readily understood on reference
to the accompanying Drawings, in which Fig. 1 shews the side view of a gun
carriage, having at a and a¹ a hinge-like joint, which can be readily separated by
withdrawing the pins 6 and 61, made somewhat taper for that purpose. The upper
part d of the carriage which carries the gun and axle is, according to requirements,
connected to one or other of the two tail pieces f and g, of which the former is of
considerably greater length than the latter, so that a considerably greater variation
in the angle of elevation can be thus obtained than with gun carriages of ordinary
construction. Fig. 1 shews the carriage with the longer tail piece f for the smaller
elevations, and Fig. 2 shews the same with the shorter tail piece g for greater
elevations. By forming the carriage of two separable pieces, as described, the
several parts are sufficiently light to enable them to be transported by beasts of
burden, for which purpose also the axle is made removeable.
The elevating of the gun is effected by means of a lever i fixed on an axis h
between the cheeks of the carriage; the outer end of the axis h carries another
lever k, whose forked end carries a screw nut working on a screw l. This screw is
carried in a pivotting bearing at m, and is rotated by a hand wheel n, by which
means the levers i and k are raised and lowered so as to lay the gun to any required
vertical angle. This arrangement of elevating gear enables the cheeks of the gun
carriage to be constructed of a more suitable form, and the parts of the mechanism
are more compact and more readily manipulated.

CARRIAGES." A communication by Otto Krell, of St. Petersburg, in the Russian
Empire.
The said improvements in gun carriages will be readily understood on reference
to the accompanying Drawings, in Fig. 1 shews the side view, and Fig. 3 a
plan of a gun carriage, having at a and a¹ a hinge-like joint, which can be readily
separated by withdrawing the pins 6 and 6' made somewhat taper for that purpose.
The upper part d of the carriage which carries the gun and axle is, according to
the requirements, connected to one or other of the two tail pieces f and g, of which
the former is of considerably greater length than the latter, so that a considerably
greater variation in the angle of elevation can be thus obtained than with gun
carriages of ordinary construction; Fig. 1 shews the carriage with the longer tail
piece for the smaller elevations, and Fig. 2 shews the same with the shorter
tail piece g for greater elevations. By forming the trail of two separate pieces, as
described, the several parts are sufficiently light to enable them to be transported
by beasts of burden, for which purpose also the axle is made removeable.
The elevating of the gun is effected by means of a lever i fixed on an axis h,
Fig. 4, between the cheeks of the carriage; the outer end of the axis h carries
another lever k, Figs. 1, 2, and 3, whose forked end carries a pivotted screw nut
working on a screw 7. This screw is carried in a pivotting bearing at m, and is
rotated by a hand wheel n, by which means the lever k is raised and lowered so
as to turn the shaft h, and thus by raising or lowering the lever i, on which the
breech of the gun rests, to lay the gun to any required vertical angle. This
arrangement of elevating gear enables the cheeks of the gun carriage to be
constructed of a more suitable form, and the parts of the mechanism are more
compact and more readily manipulated.
Having thus described the nature of this Invention, and in what manner the
same is to be performed, as communicated to me by my correspondent, I claim,―
First. Constructing the trails of guns of two separate parts connected together
by a hinge like joint, substantially as herein described.
Second. The use in combination with a gun carriage with two or more different
sized tail pieces for the trail, for obtaining greater variation for the elevation of the
gun, substantially as herein described.
Third. The use for elevating guns of an internal lever i, or arm on which the
breech of the gun bears, the said lever being mounted on an axis h, to the outer
end of which is fixed an external lever k acted upon by a screw l, substantially as
herein described.
In witness whereof, I, the said Friedrich Carl Glaser, have hereunto set
my hand and seal, the Tenth day of June, in this year of our Lord
One thousand eight hundred and eighty one.
FRIEDRICH CARL GLASER. (L.S.)
