PROVISIONAL SPECIFICATION.
Improvements in or connected with Gun Carriages.
1, AUGUST REICHWALD, of 9, New Broad Street, in the City of London, Steel,
Iron, Metal, and Mineral Merchant, do hereby declare the nature of this inven-
tion (a communication to me from abroad by the Firm of Fried. Krupp, of
Essen, in the Empire of Germany, Cast Steel Manufacturers); to be as follows:-
:-
This invention relates to an improvement upon or a modification of the wheel
carriage for high-angle firing guns, forming the subject of an application for
Letters Patent No. 25364 of 1898, and is designed to minimise the vertical force
components arising from the explosion, in such manner as to render any bracing
of the carriage against the earth unnecessary, or to allow of its being effected
by a comparatively weak support. The object in view is attained by interposing
a fluid pressure brake, between the body of the carriage, and the axle.
The general arrangement is essentially the same as that described in the
Specification of the Patent Application No. 25364 of 1898 aforesaid.
The cranked axle of the carriage, carries at its middle part the carriage body,
which turns thereon, and upon both its extremities are mounted the wheels.
Each extremity of the axle has two lugs, to one of which a spring bolt is
attached, carrying a column of spring discs upon it. The said column of discs
bear at one end against a nut on the bolt,, and at the other against a flange on
the side of the carriage. To the other lug is connected the piston rod of a
fluid pressure brake, of any well known construction, the brake cylinder of
which rocks in bearings on the sides of the carriage.
When the firing takes place, the springs will be compressed, by reason of
the relative movement of the body of the carriage and the outer ends of the axle,
and also the piston of the fluid pressure brake will be moved outwards.
Part of the recoil is thus utilized to compress the buffer springs, and another
portion is neutralized by the fluid pressure brake.
The support for the gun may be reduced in proportion to the size of this
neutralized portion of the recoil, and may therefore be made weaker, or under
certain circumstances dispensed with altogether.

I, AUGUST REICHWALD, of 9, New Broad Street, in the City of London, Steel,
Iron, Metal and Mineral Merchant, do hereby declare the nature of this inven-
tion, (a communication to me from abroad' by the Firm of Fried. Krupp, of
Essen, in the Empire of Germany, Cast Steel Manufacturers) and in what manner
the same is to be performed to be particularly described and ascertained in
and by the following statement:
This invention relates to an improvement upon the wheel carriage for high-
angle firing guns, forming the subject of Letters Patent No. 25364 dated
1st December 1898, and is designed to so minimise the vertical force components
which arise when the gun is fired that any anchoring of the gun to the earth is
rendered unnecessary or allows of its being effected by a comparatively weak
support: The end sought is attained according to the present invention by
means of a fluid pressure brake so interposed between the carriage body and its
axle that the relative movements of these parts are transmitted to the brake.
The invention is illustrated in the accompanying drawings whereon-
Fig. 1 is an elevation of the carriage in its position of rest partly in
section, and
Fig. 2 is an elevation of the carriage shewing the carriage body in its lowest
position.
The general arrangement is essentially the same as that described in the
Specification of Letters Patent 25364/98 aforesaid.
carriage body is
of the axle.
In the lug
is
The carriage axle is cranked, and at its middle part m the
free to turn, while the wheels revolve upon the cranked ends
Each limben of the axle is furnished with two lugs a, e.
pivotted the spring bolt which slides in a guide block d free to turn on the.
carriage body. The spring bolt & carries a column of springs one end of which
bears against the nut c screwed ou the said bolt b, and at its other end against
a flange g formed with a slot & Fig. 1, on the wall of the carriage.
Pivotted to the lug c is the piston rod h of a fluid pressure brake, the brake
cylinder of which is mounted to rock on the carriage body by means of a
pivot, so that it may be capable of swinging against the carriage axle when the
carriage body is moved.
In other respects the fluid pressure brake in construction and operation is
similar to any ordinary known fluid pressure brake.
The operation of the device is as follows:-
When the gun is fired the relative motion of the carriage body and the
axle n, acts not only as described in the Specification of Patent aforesaid to
compress the springs f, but acts also to move the piston of the fluid pressure
brake outwards, which thus exerts a braking action. A portion of the recoil is
thus utilized to compress the buffer springs, and another portion neutralised by
the fluid pressure brake. The anchor is reduced in proportion to this latter
portion of the recoil and may thus be made of lighter form or under some cir-
cumstances be dispensed with entirely.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. A form of construction of the wheel carriage for high-angle firing gun3
of the type described in the Specification of Letters Patent 25364 of 1898. in

page_text: which the relative motion of the carriage body to the axle is transmitted to a
fluid pressure brako substantially as set forth.
2. The particular arrangement and combination of parts, composing my
improvements in high-angle firing gun-carriages,, of the type described in Patent
Specification 25364 of 1898, constructed and acting substantially as and for the
purposes described with reference to the accompanying drawings.
