LOUIS VON LÜBBE Gentleman 30 Grove Road St. John's Wood N.W. do hereby
declare the nature of this invention to be as follows:-
I claim to increase the power applicable to the propulsion of rear driver bicycles &
tricycles & thereby the speed at which they may be driven without materially
increasing the weight of the machine by applying to the front wheel one or two of
the ordinary two wheels & chain motions such motion or motions to be worked by a
rod connected with the handle & workable by the hand or hands without interfering
with the proper steering or breaking of the machine & so arranged as to be used or
left out of use at the option of the rider & the need he may or may not feel for
increased power & speed.

An Auxiliary Hand-driving Arrangement for Bicycles and
Tricycles.
I LOUIS VON LÜBBE of 30 Grove Road St. John's Wood in the County of
Middlesex, Gentleman 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 :—
My invention has for its object to increase the power applicable to the propulsion of
rear-driver bicycles tricycles and other velocipedes and thereby the speed at which
they may be driven by adding to the feet driving arrangement a hand driving
arrangement. For this purpose I apply to the front wheel one or two of the ordinary
wheel-and-chain motions or of the ordinary wheel-and-pinion motions and work the
same by means of rods connected to levers having the fulcrums on the front bar or
stem of the machine. I place the fulcrums of the levers upon the front bar or stem
of the machine as it is the front bar by which the machine is steered and this secures
to the bar in all circumstances a position parallel to that of the spindle of the wheel
and thus permits of the wheel-and-chain or wheel-and-pinion motions being worked
from it without jamming. And in order the better to apply and work the levers
I dispense with the right hand end of the front bar and attach the brake lever, where
a brake is considered necessary, to the left hand end of the bar. The simplest
application of my auxiliary hand driving arrangement is that in which one wheel-and-
chain or wheel-and-pinion motion is made use of and this is fixed on the left side of
the front wheel and worked by a single lever.
In cases where my auxiliary hand driving motion is applied to both sides of the
machine work the two wheels by means of one lever. The connecting rod for
working the left hand motion is fitted to the end of the lever and from the same point
is worked another lever whose fulcrum is on the stem of the machine, and the ends of
which are equi-distant from the fulcrum, and to the other end of this second lever is
fitted the connecting rod by which the right hand motion is worked.
second lever parallel with the front bar of the machine. The lever with the handle

extending to the right is placed in a diagonal position so as to bring the handle into a
position convenient to the rider. The same arrangement of levers and connecting
rods is adopted where only one wheel-and-chain or wheel-and-pinion motion is used
and the other end of the wheel spindle is fitted with a crank.
As the levers thus placed are nearly at right angles to the spindle of the wheel they
drive the are they describe gives to the connecting rods an oscillating motion
sidewards, and I therefore make the studs or pins which are fitted into the wheel and
crank ball shaped, and apply to them connecting rods A, fitted with caps and the
end of the connecting rods and the inside of the caps are hollowed so that when the
cap is fixed the connecting rod encloses the ball and forms a joint which works smooth
and easy.

fulcrum of this lever is in a bracket d fixed on the stem of the machine and is placed

veniently accessible to the right hand of the rider B.
Like the ends of the levers to which the connecting rods are attached the crank
pins are ball shaped and hoth ends of the connecting rods are alike C.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1-The application of a hard-driving arrangement to the front wheel or wheels of
rear-driver bicycles, tricycles and other velocipedes.
2-A ball joint for the working of my hand driving arrangement in which steel
pellets are made use of to form the bearings in which the ball works.
3-A mud guard with a feather in the centre as described required to make
up for the brake being dispensed with in the application of my hand-driving
arrangement.
