PROVISIONAL SPECIFICATION.
An Improved Brake for Use on Traction Engines or the like.
1, ALFRED GANDER, of 39 Bonchurch Road, Hassocks, Engineer, do hereby
declare the nature of this invention to be as follows:-
My invention relates to an improved brake for use on traction and like engines,
and consists essentially of a rod of suitable length, a spring clip, handwheel and nut.
The whole is fastened by nuts or other means suitable for the purpose to the
pedestal supporting the flywheel. The spring clip is passed round the crank shaft,
preferably near said flywheel.
The nut is fixed to or formed integral with the clip before mentioned.
thread is fashioned on the rod of same pitch as the thread in this nut.
A screw
To apply the brake, the handwheel at the end of the rod is turned, this causing
the nut on same to move forward, causing the spring (by being attached thereto)
to contract, bringing pressure to bear on the crank shaft.

I, ALFRED GANDER, of 39, Bonchurch Road, Hassocks, Engineer, 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 :-
My invention relates to an improved brake for use on traction and like engines,
more especially those used for agricultural purposes, and consists essentially of a
rod of suitable length, a spring clip, a hand-wheel and nut.
At present when two engines are ploughing the self acting brake usually fitted
on the winding drum of each, varies considerably in efficiency according as the
weather is wet or dry, and it does not grip sufficiently, to keep the rope tight on
the drum say of engine number one, when engine number two is drawing the plough
or the like, and vice versa, and if the rope is not kept tight, it is liable to be spoiled
or damaged, so much so as to often necessitate the stopping of the work in haud in
order that it may be set right. Now the advantage of my improved brake is that
the engine driver can stand on his engine and put the required pressure on the
upright shaft by means of the rod and hand-wheel connected to the brake, so as to
keep the rope running tight on the winding drum. The brake consists essentially
of a wood lined, steel spring clip, attached to the main frame of the engine by a
suitable bracket. This clip surrounds the greater part of the circumference of the
running shaft which drives the spur wheel of the rope winding drum, the clip being
caused to more or less grasp the shaft and retard its motion, by means of a screw
threaded rod working through the bracket and in a nut or collars attached to the
spring clip. The rod is rotated and the brake brought into action by turning the

page_text: hand-wheel of another rod attached to the first mentioned one, by a universal joint.
In order that my invention may be the more readily understood, I make reference
to the accompanying sheet of drawings, in which,

Fig. 2 a cross section of the shaft shewing the brake "tight" and exerting its
full grip.
Fig. 3 a cross section of the shaft shewing the brake “loose," and
Fig. 4 a front view of the bracket for holding the brake to the engine frame.
Similar letters refer to the same parts in each figure.
a is the boiler, the flywheel, c the vertical running shaft driving the spu
wheel d of the rope winding drum e. f is the screw-threaded rod working through
the bracket 9 and running in the collars . To the collars is attached one end of
the steel spring clip i the other end thereof being bolted, rivetted, studded, or
otherwise fastened to the bracket g. The clip is lined with wood blocks j.
is the universal joint connecting with the rod 7 carried by the bracket m and
furnished with the wheel handle n. o is the foot-plate of the engine. The action
of the brake is as follows.-(assuming it to be "
"
loose as in Fig. 3).
On turning the handle n the rods and will be rotated. As the screw threaded
end of turns in g it will draw up the collars and cause the spring clip i to
tighten up the wood blocks, on to the shaft e and so retard its rotation.
I do not restrict myself to the precise details, configurations, relative proportions
or disposition of parts as described in the above Specification or exemplified in the
drawings, as any or all of them may be considerably varied, without departing
from the spirit of my invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
:―
1. An improved brake for use on traction engines or the like and consisting
essentially of a wood lined spring clip embracing the greater part of the circum-
ference of the shaft driving the rope pully of the engine and caused to grip the
said shaft as and when required by the rotation of a screw threaded rod working
in a bracket attached to the frame of the engine, the whole substantially as
described in the above Specification and exemplified in the accompanying
drawings.
2. The combination of parts, substantially as described in the above Specification
and exemplified in the accompanying drawings, and together forming and operating
as an improved brake for use on traction engines or the like.
Dated this 27th day of March 1896.
