I, HENRY HARRIS LAKE of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings in the County of Middlesex, do hereby declare the nature of
of this invention to be as follows:-
This invention relates to an automatic brake capable of being applied to any vehicle
and has for its object the construction of a brake that will be applied and released
automatically without any attention from the driver of the vehicle.
When the vehicle has four wheels I prefer to arrange the brake so that it will act
on the two in front.
The brake is double, that is to say, it comprises brake shoes designed to press upon
both wheels of the vehicle. Each shoe is actuated by an arm the prolongation of
which forms a connecting rod pivoted or jointed to an eye of the side bar in such a
manner that the arm is capable of moving upwards but not downwards. The side bar
of the vehicle is pivoted or jointed in connection with a small lever with which it forms
almost a right angle. This small lever is pivotted in a fork formed at the extreme
end of the shaft, and its extremity is provided with an eye through which passes the
end of a connecting rod actuating the brake shoe or brake of the second wheel placed
upon the same axle as that under consideration.
the
The same mechanism is adapted to the second wheel so as to act upon
connecting rod actuating the brake shoe for the first wheel that is to say, the lever
attached to the off shaft applies the brake to the near wheel, and the lever attached
to the near shaft applies the brake to the off wheel, the levers thus crossing one
another.
When for example the vehicle is upon an incline, the horse when holding back or
restraining itself, will push upon the side bars and cause them by means of the above
mentioned levers to bear upon the said connecting rod and to occasion the latter to
act upon the arm of the other wheel with which it is in connection as above
stated.

page_text: As above stated, when the vehicle descends an incline the horse applies the brake
by holding the vehicle more or less back and thereby causes the side bars to push
upon the levers which apply the brake; the more sloping the incline is, the greater
will be the force exerted by the horse, so that the brake will be applied more or less
strongly against the wheel. When on level ground, the brake shoe will be separated
from the wheel because the horse exerts then traction. In case of stopping, the
horse by holding back will forcibly press the brake shoes against the wheels.
My brake system is also applicable to vehicles for two horses, but in this case the
motion is not crossed. The shaft is provided at its free extremity with two hinge
motions, part of which terminates in a ring through which the rein fixed to the
collar of the horse passes, the other extremity is adapted to a rod or rope passing
under the shaft and kept there by means of ring nails; the other end of the rod
or rope is attached to the extremity of the lever which actuates the lever applying
the brake shoe, and is pivotted upon the prolongation of the fore carriage of the
vehicle.
With this mechanism when the horses push or hold back, they pull the small
connecting rod thus causing the rods or ropes to pull the connecting rods carrying
the brake shoes so that they will be applied to the wheels.
This invention can also be applied to vehicles driven by steam, in which case the
levers are placed at points where the locomotive is attached to the wagon or wagons,
and in such a manner that the brake will be actuated by the buffers.

page_text: Southampton Buildings, in the County of Middlesex, 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 relates to an automatic brake capable of being applied to any vehicle
and has for its object the construction of a brake that may be applied and released
automatically without the attention of the driver or other person.
In the accompanying drawings I have shown how the said invention may be
conveniently and advantageously carried into practice.
Figure 1 is a side view of the fore part of a one-horse vehicle provided with the
improved brake acting in the direction of the arrows.
Figure 2 is a front view and
Figure 3 is a plan of the same.
Figure 4 is a plan of the fore part of a vehicle for two horses, and
Figure 5 a side view of the shaft of the same.
When the vehicle has four wheels the brake is double, that is to say, it comprises
brake shoes A designed to press upon both the front wheels of the said vehicle. Each
shoe is actuated by an arm B the prolongation of which forms a connecting rod E
pivoted or jointed at G to an eye of the side bar in such a manner that the arm B is
capable of moving upwards but not downwards; as seen in Figure 1, the side bar of
the vehicle is pivoted or jointed at C in connection with a small lever D with which it
forms almost a right angle. This small lever is pivotted at F in a fork formed at the
extreme end of the shaft, and its lower extremity is provided with an eye D¹ through
which passes the end of the connecting rod E actuating the brake shoe or brake of
the wheel placed upon the opposite end of the axle as that above mentioned.
The same mechanism is adapted to the second wheel so as to act upon the connecting
rod actuating the brake shoe as for the first wheel, that is say, the lever which is
actuated by the off shaft applies the brake to the near wheel, and vice versa, the said
levers thus crossing one another.
When for example the vehicle is upon an incline, the horse when holding back or
restraining itself, will put its power upon the hind gear pushing upon the side bars or
shafts in the direction of the arrows thereby turning the levers D, D, upon their pivots
and operating the levers E to apply the brakes.
As above stated, when the vehicle descends an incline the horse applies a brake by
holding the vehicle more or less back and thereby causing the side bars to push upon
the levers which apply the brakes; the more sloping the incline is, the greater will be
the force exerted by the horse so that the brake will be applied with greater force
against the wheel. When on level ground, the brake shoe will be separated from the
wheel because the horse will then pull upon the shafts. In case the vehicle is stopped,
the horse by holding itself back will forcibly press the brake shoes against the
wheels,

page_text: As shown in Figures 4 and 5 the improved brake is also applicable to vehicles for
two horses, but in this case the motion is not crossed. The shaft or pole is provided
at its free extremity with two hinged levers. F, F, one extremity of which terminates
in a ring through which the rein fixed to the collar of the horse passes, the other
extremity being connected to one end of a rod or rope G passing under the shaft and
kept there by means of eyes H, H; the other end of the rod or rope G is attached
at I to the extremity of the lever E for applying the brake shoe, and which is pivoted
at c upon the prolongation of the fore carriage of the vehicle.
With this mechanism when the horses push or hold back they pull the small
levers F, F¹ thus causing the rods or ropes G.to pull the connecting rods E carrying
the brake shoes so that they will be applied to the wheels.
The arrows in Figure 5 show the direction of motion of the different parts.
The improved brake can also be applied to vehicles driven by steam, in which case
the levers F, F¹, are placed at points where the locomotive is attached to the
wagon or wagons and in such a manner that the brake will be actuated by the
buffers.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed as communicated to me by my
foreign correspondent I declare that what I claim is :-
First. An automatic brake which is actuated by the restraining action which is
imparted to the vehicle by the horse or horses or by a locomotive or oven by hand, the
said brake consisting of a combination of levers conbined with the shaft or shafts of a
vehicle or of the pole of a vehicle as indicated in the accompanying drawing, the
shoe A being provided with an arm B attached to a connecting rod E exerting a
pressure on the said shoe when the horse or the locomotive stops or moves backwards
by reason of the fact that the side bar or shaft of the vehicle then pushes upon the
extremity F of a lever D pivoted at C¹ in a fork formed upon the extremity of the
arm for securing the side-bar projecting from the fore-carriage of the vehicle,
the extremity of the lever D carrying an eye to receive the extremity of the
connecting rod E of the brake of the other wheel for actuating the latter in a cross
motion, the whole as described and represented in the accompanying drawing.
Second. The improved brake actuated by a device based upon the principle of levers
placed at the fore-carriage and capable of being doubled in order to enable the action
of a side-bar or pole to bear directly upon the wheel which is nearest to it, as repre-
sented in the drawings.
