Improvements in and relating to Brakes.
I, NICOLAS VINCKE of 78 Rue Leopold, Malines in the Kingdom of Belgium,
Manufacturer, 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:-
The present invention relates to an instantaneous action brake which is appli-
cable to all shafts or dises having a rotary motion, but is more particularly
intended for stopping vehicles travelling at a nigh speed, such as autocars.
This brake acts instantaneously and can be operated with great ease and
without appreciable effort.
The accompanying drawing illustrates by way of example one arrangement of
my new brake applied to an autocar.
Figure 1 is a view in side elevation,
Figure 2 is a view in plan, and
Figure 3 is a view of the drum showing haw the narrow parts of the band
overlap the large part.
Figure 4 is a view in elevation--on an enlarged scale-of the brake band and
attachment and
Figure 5 is a plan view thereof.
Throughout the views similar parts are marked with like letters of reference.
The brake consists of a band or strin A which is of double width at its central,
part as compared with its two ends which are each of single width only. That is
to say the central portion has the appearance of being formed by the arrangement
side by side of two bands or strips of one single width each.
This central portion is wound on the inner shoulder or collar of the hub, and
its ends make a further half-convolution, one end being then fixed to the shaft B
situated near the wheels, whilst the other end is fixed to an arm which is capable
of movement on the shaft B and is adapted to be shifted and fixed on a sector D.
(which is furnished with several rows of apertures) by means of a pin g. This
sector forms one piece with the shaft B which carries a second arm E to which
there is jointed one of the ends of the bar or connecting rod F the other end of
which is jointed to a lever G whose fulcrum is constituted by a pivot provided
on the vehicle in proximity to the feet of the driver. The point of application
of the power is constituted by a pedal or treadle H upon which it is sufficient for
the driver to press gently with his foot in order to cause the brake to act.
It will be readily understood that this brake is certain in its operation and is
extremely effective, whilst it is capable of stopping within a few metres a vehicle
travelling at a speed of 30 kilometres per hour. The efficiency of the brake and
its certainty in operation is ensured by the rotary motion of the wheel itself,
said rotary motion having the result of drawing the angles or edges of the central
portion or portion of double width of the band or strip, powerfully towards one
another, so soon as a slight pull is exerted upon its ends.

page_text: 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.) An instantaneous brake for all rotary discs or shafts, and particularly for
the wheels of autocars, characterized by the arrangement of a band or strip cut
out or cut away at its two ends in opposite directions in such a manner as to form
a central portion of double width as compared with the end portions, said band
or strip being wound or coiled one and one half times upon the inner shoulder or
collar of the hub and being arranged to be actuated by means of mechanism com-
prising a lever, connecting rod, and pedal or treadle, substantially as described
and shown.
Dated this 10th day of February 1897.
