Improvements in Brakes for Gun Carriages and other Vehicles.
ALFRED STEVENS, and WILLIAM STEPHEN PENNEY, both of St. Lawrence, Rams-
gate, Boatbuilders, do hereby declare the nature of this invention to be as
follows:-
This invention consists of improvements in or relating to brakes for use with
artillery, such as gun carriages, transport and other vehicles. In gun carriages
and other vehicles employed for use with artillery, it is most essential that they
may be braked so as to enable them to be more or less guided or steered and
also stopped when required. In order to attain this result, we find it convenient
to provide two pins or pivoted braking surfaces which are adapted to grip the
required part to be braked, such as the nave of the wheel or the axle thereof
according to which of these two rotate, that is to say, the gripping or braking
action takes place upon the rotating surface to be braked. In the case of a
gun carriage in the event of the wheels not having projecting surfaces or naves
upon their interior sides, I may arrange the brake to be applied upon the exterior
nave or projection of the wheels, but it will be readily seen that the wheels may
be provided with projections or naves upon their interior surfaces if it is found
more convenient to apply the braking surfaces to the interiors. For the purpose
of operating the braking surfaces I find it convenient to connect them to suit-
able levers or bars of a configuration adapted to the purpose and position in
which they are used. These levers or bars are carried in suitable bearings and
may be adjusted, being operated through the medium of any convenient form of
mechanism so as to enable the brakes to be. so applied as to grip or bear upon
one or other of the wheels or both of the wheels, simultaneously as desired. I
effect this object by so connecting the operating lever through the medium of
suitable toggle joints and cranks as to enable either of the wheels to be. braked
separately or simultaneously according to the direction of movement of the
operating lever. This direction of movement may be predetermined and arranged
according to the arrangement of the connecting mechanism between the operating
lever and the rods or bars actuating the braked surfaces. For instance, the operating
lever may be connected to rods or bars which are in turn connected to cranks or toggle
joints for the purpose of enabling one or other of the wheels to be braked when the
lever is moved or rocked from--for purpose of illustration we will call right to
left. This operating lever is also connected through the medium of another rod
or bar or such suitable means to a toggle joint or crank arrangement or other
convenient mechanical means for bringing the bars or rods attached to the
brake into position, so as to grip both wheels simultaneously, and this action
might be effected through a backward or forward movement of the lever afore-
said, or the various joints and connections might be so arranged as to give a
differentiation between the braking action, that is to say, one or other of the
wheels might be more or less braked in conjunction with the other.

ALFRED STEVENS and WILLIAM STEPHEN PENNEY, both of St. Lawrence, Rams-
gate, Boatbuilders, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
-
This invention consists of improvements in or relating to brakes for use with
artillery, such as gun carriages, transport and other vehicles. In gun carriages
and other vehicles employed for use with artillery, it is most essential that they
may be braked so as to enable them to be more or less guided or steered, and at the
same time stopped when required. In order to carry out this object, we find it con-
venient to provide two pins or pivoted braking surfaces which are adapted to grip
the required part to be braked, such as the nave of the wheel or the axle thereof,
according to which of these two rotate, that is to say, the gripping or braking
action takes place upon the rotating surface to be braked. In the case of a
gun carriage, in the event of the wheels not having projecting surfaces or naves
upon their interior sides, we may arrange the brake to be applied upon the exterior
nave or projection of the wheels, but it will be readily seen that the wheels may
be provided with projections or naves upon their interior surfaces if it is found
more convenient to apply the braking surfaces to the interiors. For the purpose
of operating the braking surfaces we find it convenient to connect them to suit-
able levers or bars of a configuration adapted to the purpose and position in
which they are used. These levers or bars are carried in suitable bearings and
may be adjusted being operated through the medium of any convenient form of
mechanism, so as to enable the brakes to be so applied as to grip or bear upon
one or other of the wheels, or both of the wheels simultaneously as desired. We
effect this object, by so connecting the operating lever through the medium of
suitable toggle joints and cranks, as to enable either of the wheels to be braked
separately or simultaneously according to the direction of movement of the
operating lever. This direction of movement may be predetermined and arranged
according to the arrangement of the connecting mechanism between the operating
lever and the rods or bars actuating the braked surfaces. For instance, the operating
lever may be connected to rods or bars which are in turn connected to cranks or toggle
joints, for the purpose of enabling one or other of the wheels to be braked when the
lever is moved or rocked from for purpose of illustration we will call--right to
left. This operating lever is also connected through the medium of another rod
or bar or such suitable means, to a toggle joint or crank arrangement or other
convenient mechanical means for bringing the bars or rods attached to the
brake into position, so as to grip both wheels simultaneously, and this action
might be effected through a backward or forward movement of the lever afore-
said, or the various joints and connections might be so arranged as to give a
differentiation between the braking action, that is to say, one or other of the
wheels might be more or less braked in conjunction with the other.
Referring to the annexed drawings:
Figure 1, is a plan view shewing our invention.
Figure 2, front elevation of same.
Figure 3, view of operating lever detached.
The brake surfaces are carried in the holders b, pivotally secured at c to a
suitable part of the frame or other position. d are connecting rods or bars
adjustably carried at e to the holders 6 carrying the brake surfaces, these rods
or hars d being connected to the toggle joints f and g, which are operated by
the levers and as shewn, these levers being connected through the bars j

page_text: to the operating lever k, which is provided with the universal joint l. m is a
lever which operates the lever n pivoted at o and having arms p and q or con-
necting rods, attached to the rods or bars d. It will be seen that by operating
the lever from side to side, in the direction of the arrows 1 and 2, one or other
of the wheels and s will be braked, viz. that one towards which the lever k is
operated, and by moving the lever in the direction of the arrow 3, the braking
surfaces will be applied to the wheels simultaneously.
Although this arrangement is particularly applicable to gun carriages, one of
which is represented by the reference letter 1, it will be seen that there are other
uses to which the invention may be put, so we do not confine ourselves to this
particular way.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
1. In brakes for military use, such as artillery, transport and other vehicles,
the combined construction and arrangement of the various parts, substantially
as described and illustrated herein and for the purpose set forth.
2. In brakes for military use, such as artillery, transport, and other vehicles,
two pivoted braking surfaces adapted to grip a suitable part of the wheel or axle,
for the purpose of braking, said braking surfaces being adjustably connected
to bars or rods; an operating lever carried by a universal joint and connected
through the medium of the rod to a lever, which is in turn pivotally connected
to the operating bars or rods, supplementary levers connected to said operating
lever and operating mechanism, for applying the brake, such as a toggle joint,
upon either wheel, according to the direction of movement of the operating lever,
substantially as described and illustrated herein and for the purpose set forth.
