Improvements in or relating to Velocipedes and other Vehicles.
We, NICOLAS ALPHONSE AUBERTIN, of 120, Tottenham Court Road, in the
County of London, Engineer and Chemist, and BERTIE HALLETT, of 75, Queen
Victoria Street, also in the County of London, Gentleman, do hereby declare
the nature of this invention to be as follows:-
This invention is designed to enable a person to exert a very great pushing
force with his feet in order to propel a vehicle having a load with very little
exertion.
It is well known that a person can exert a very great pushing force with his
feet when he has a purchase for his back or shoulders, on account of the powerful
muscles of the trunk being brought into use as well as those of the legs.
In order to make use of this great power for the propulsion of velocipedes, or
other vehicles, we provide a driver's seat with a back or rail, which may be
adjustable or not, so that it may come against the back or shoulders of the
driver, in order to obtain the required purchase, and in conjunction with this
seat we employ a swinging treadle, preferably such as that described in Letters
Patent granted to N. A. Aubertin, dated 19th December 1894, No. 24,711. We
may in some cases prefer to employ a saddle such as that described in the Specifi-
cation of the Letters Patent granted to B. Hallet, dated 5th June 1893,
No. 10,954.
Improvements in or relating to Velocipedes and other Vehicles.
We, NICOLAS ALPHONSE AUBERTIN, of 120, Totten Court Road, in the County
of London, Engineer and Chemist, and BERTIE HALLETT, of 75, Queen Victoria
Street, also in the County of London, Gentleman, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:-
-
This invention is designed to enable a person to exert a very great pushing
force with his feet in order to propel a vehicle having a load with very little
exertion.
It is well known that a person can exert a very great pushing force with his
feet when he has a purchase for his back or shoulders, on account of the powerful
muscles of the trunk being brought into use as well as those of the legs.

page_text: In making use of this great power for the propulsion of velocipedes or like
vehicles, we provide the driver's seat with a back or rail, which may be adjust-
able or not so that it may come against the back or shoulders of the driver, in
order to obtain the required purchase and in conjunction with this seat, we
employ a swinging treadle, preferably such as that described in Letters Patent
granted to N. A. Aubertin, dated the 19th December 1894 No. 24711.
The cycle may be propelled by one foot only.
And in order that our said invention may be better understood we will now
proceed to describe the same with reference to the drawings accompanying
this specification, in which, Fig. 1 shews- an elevation of a small carriage or
tricycle for carrying two persons as well as the driver. This carriage is_shewn
provided with swinging treadles as described in the aforesaid former Letters
Patent granted to N. A. Aubertin. Fig. 2 shews a plan of carriage shewn at
Fig. 1.
The same letters denote the same parts in both the views.
;
a shews body of carriage, in dotted lines, this would be mounted on suitable
springs shews the saddle for the driver, and d back of same. f f are rods
pivotted at g, one on each side of the frame. The pedals are attached at h h
to the lower ends of the swinging rods ff. ii are connecting rods from the
swinging rods, f f, to the cranks j j. k is a sprocket wheel fixed to the crank
spindle for driving a pinion on the axle of the back wheels p p by means of a
chain in the ordinary way.
The treadle rods are so set that the rider is enabled to exert the maximum
amount of force in the most favorable direction.
Steering may be effected in the most suitable way according to the method
of driving.
In propelling the vehicle. the driver seated on the saddle c with his shoulders
against the back rest d and his hands gripping the handles on the handle har
(which is not shewn on the drawings) gives his legs or leg a swinging motion
from the knees or knee so that the muscles of the hack and shoulders, arms and
other parts of the body are brought into action besides those of the leg or legs.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
In velocipedes, the combination of swinging treadles with a back for the
driver to rest his shoulders against for the purposes set forth.
