Improvements in Brake Mechanism for Carriages or other
Vehicles.
We, COUNT ALBERT DE DION and GEORGES BOUTON both of Puteaux
(Seine) in the Republic of France, Builders, do hereby declare the nature of this
invention to be as follows:-
Our invention relates to brake mechanism for carriages or other vehicles and has
for its object to provide an arrangement whereby the power applied is equally
distributed to each of the brake shoes.
According to our invention the levers or the like by means of which motion is
communicated to the brake levers are secured to the ends of two shafts in line
with each other and supported in any suitable way from the frame of the vehicle.
On the adjacent ends of these two shafts are secured bevel toothed wheels cach
engaging with a bevel toothed pinion situated between them and mounted on a
pivot on a sleeve capable of turning freely on the two adjacent ends of the said
shafts to which sleeve is affixed the pedal or other device by which the brake is
operated.
When the pedal or other device is operated the pinion turns around the shafts
but remains immovable on its pivot and by means of the bevel wheels transmits
movement of rotation to the two shafts until one of the brake shoes has come
into contact with the corresponding wheel and then as the shaft pertaining to
this shoe is no longer able to turn, the pinion bears against the toothed wheel on
the end of the said shaft and in turning on its pivot rotates the other shaft
until the brake shoe operated thereby has come into contact with its wheel.
When the two brake shoes are thus brought into contact with their respective
wheels the pinion ceases to turn on its pivot and at the same time bears upon both
toothed wheels at the ends of the two shafts and thus the force applied is equally
distributed over the two brake shoes. The brakes may be applied by the drivers
foot or by hand or from a screw shaft operated by a fly-wheel or in any other
suitable way.

Improvements in Brake Mechanism for Carriages or other
Vehicles.
We, COUNT ALBERT DE DION, and GEORGES BOUTON, both of Puteaux
(Seine) in the Republic of France, Builders, do hereby declare the nature of this
invention aud in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
Our invention relates to brake mechanism for carriages or other vehicles and is

page_text: designed to provide an arrangement whereby pressure can be applied equally to both
of the brake shoes when the brake mechanism is operated.
According to our invention 'the levers or other means by which motion is commu-
nicated to the brakes, are secured to the outer ends of two shafts which are in line
with each other and supported in any suitable manner from the frame of the vehicle.
On the inner or adjacent ends of these two shafts are secured bevel wheels each
engaging with a bevel pinion situated between them and mounted on a pivot carried
by a sleeve which is capable of turning freely on the two adjacent ends of the said
shafts, the pedal or other device by which the brake is operated being attached to
or projecting from this sleeve.
In order that our said invention may be readily understood we will proceed to
describe the same more fully with reference to the accompanying drawings in
which
Figure 1 is an elevation of one arrangement of our improved brake operating
mechanism.
Figure 2 is a plan, and
Figure 3 is a side view of the same.
a a are the two shafts arranged in line with each other and serving to operate
the brakes through the medium of arms b and links or rods c. dd' are the two
bevel wheels secured on the inner ends of these shafts an1e is the bevel pinion
situated between them. f is the sleeve arranged on the adjacent ends of the
shafts a a¹ and carrying the pivot of the pinion e. g is the pedal by which the
brake is operated, this pedal being carried by a rod or lever y extending from
the sleeve f.
It will thus be seen that the wheels d d' and the pinione form an epicyclic gear
and that when the pedal g is depressed the pinion e being on the opposite side of
the sleeve will be raised. This pinion being engaged on opposite sides by the
wheels d and d¹ does not at first rotate as it rises but imparts augular movement to
each of the said wheels, sufficient to apply the brakes. When one of the brakes,
say that operated by the wheel d, has been applied, the said wheel is therefore
brought to rest, and the pinion e now commences to rotate on its pivot e', thereby
rotating the other wheel d' at a greater speed until the second brake is applied.
The arrows on the drawings indicate the directions in which the parts c and g
'move when operated to apply the brakes.
с
When the two brake shoes are applied to the wheels of the vehicle the pinion e
is unable to turn on its pivot, but continues in gear with both toothed wheels d and d¹
thus distributing equally between the two brake shoes the force communicated to
it by the pedal.
The lever g¹ for applying the brakes instead of being operated by the foot of the
driver may be operated by hand by means of a screw shaft actuated by a hand
wheel or in any other suitable way.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:-
Brake mechanism provided with gearing for transmitting the power equally to
both brake shoes, substantially as described with reference to the accompanying
drawing.
