BRAKE AND STARTING APPARATUS FOR WHEELED VEHICLES to be as follows:
Year: 1884

page_text: I, MARK FRANCIS JAMES MANN of No 59 West Cromwell Road Kensington in
the County of Middlesex, Tutor, do hereby declare the nature of my said invention
for "BRAKE AND STARTING APPARATUS FOR WHEELED VEHICLES to be as
follows:-
"
My invention relates to apparatus, applicable to wheeled vehicles, to act as a
brake for retarding and stopping the vehicle when it is relieved from the traction
of the horses or other motor employed to drag it, and thereby to store up a certain
amount of force, which, when the vehicle is afterwards subjected to traction, aids
in starting it.
For this purpose, I mount, concentrically with a wheel of the vehicle, a barrel
containing a strong volute spring, both the barrel and also its axis having on them
ratchet wheels with opposite teeth, in which engage pawls mounted on the body of
the vehicle. The barrel and its axis are connected together through sun and planet
gear, the planet being mounted on the wheel of the vehicle or on a crank arm of
its axle and revolving with it.
The two pawls above mentioned are so connected to a spring draw bar or to
drag-links to which the tractive force is applied, that when the vehicle is dragged
in the one direction, one of the pawls is engaged and the other is disengaged, and
when the vehicle is dragged in the opposite direction, the condition of the pawls is
inverted. While the tractive force is acting on the draw bar or link, the then
engaged pawl allows the ratchet wheel with which it is engaged to turn freely, and
consequently the spring with its barrel and gearing mercly revolves with the
wheel of the vehicle. But, when the tractive force ceases, the other pawl coming
into gear with its ratchet prevents the system from revolving as a whole, and
consequently the spring is wound up, opposing the rotation of the wheel and so
retarding the vehicle." When again the tractive force applied, the spring
unwinds itself, and in so doing exerts a force tending to turn the wheel of the
vehicle and thus aids in starting it. The apparatus above described may be applied
to two or more of the wheels of the vehicle.

I, MARK FRANCIS JAMES MANN, of N° 59 West Cromwell Road, Kensington in
the County of Middlesex, Tutor, do hereby declare the nature of my invention
for BRAKE AND STARTING APPARATUS FOR WHEELED VEHICLES "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 apparatus applicable to wheeled vehicles, to act as a
brake for retarding and stopping the vehicle when it is relieved from the traction
of the horses or other motor employed to drag it, and thereby to store up a certain
amount of force, which, when the vehicle is afterwards subjected to traction, aids
in starting it.
For this purpose, I mount, on the vehicle, apparatus such as I will describe
referring to the accompanying drawings. Fig. 1 is a view of a wheel of the vehicle,
Fig. 2 is a part transverse section and Fig. 3 a part longitudinal section of the
lower part of the vehicle showing apparatus according to my invention applied
thereto. Concentrically with a wheel W of the vehicle, I mount a barrel B
containing a strong volute spring V both the barrel B and also its axis A having
on them ratchet wheels R R' with opposite teeth, in which engage pawls P Pi
mounted on the body of the vehicle. The barrel B and its axis A are connected
together through sun and planet gear, the planet S being mounted on the wheel of
the vehicle or, as shewn in Fig. 2, on a crank arm C of its axle and revolving
with it.
The two pawls P P¹ are so connected to a spring draw-bar D or to drag links
to which the tractive force is applied, that when the vehicle is dragged in one
direction, one of the pawls is engaged and the other is disengaged, and when the
vehicle is dragged in the opposite direction, the condition of the pawls is inverted.
This is effected by means of an arm E jointed to the drawbar D and sliding
through a socket on a sleeve F embracing the axle. On the sleeve F are two cam
protuberances G one of which, according as the drag is in the one or the other
direction, lifts one of the pawls P P'. While the tractive force is acting on the
draw bar or link, the then engaged pawl allows the ratchet wheel with which it is
engaged to turn freely, and consequently the spring with its barrel and gearing
merely revolves with the wheel of the vehicle. But, when the tractive force
ceases, the arm E takes a middle position allowing the other pawl to come into
gear with its ratchet. This prevents the system from revolving as a whole, and
consequently the spring V is wound up, opposing the rotation of the wheel W and
so retarding the vehicle. When again the tractive force is applied, the one pawl or
the other is withdrawn, the spring unwinds itself, and in so doing, exerts through
the planet wheel S a force tending to turn the wheel of the vehicle and thus aids in
starting it. The apparatus above described may be applied to two or more of
the wheels of the vehicle.

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
In combination with a wheel or running axle of a vehicle, a planet wheel driven
thereby and gearing with two wheels the one on the barrel and the other on the
axis of a volute spring each of these having a ratchet wheel with pawl worked by
the tractive force substantially as and for the purpose herein set forth.
