DIICHHIC,
do hereby declare the nature of this invention to be as follows:-
The invention consists in the use of a forked lever extending behind the hind
wheel to a point approaching the front of the frame between the legs of the
rider and easily reached by his hand.
On the front of the seat standard and between the top and bottom frames a
quadrant-shaped ratchet is fixed vertically.
A spring pawl in the interior of lever controlled from the handle end engages
with the teeth of the ratchet and keeps the lever fixed at the heighth desired.
The forward or handle end of the lever is hollow and in one piece until it
reaches the ratchet where it is slotted so as to embrace this and thence the lever
spreads out into two prongs one on either side of the hind wheel. These prongs
are pivotted on the axle of the hind wheel or on studs fixed to the frame near the
latter, or in some analogous way or position, and afterwards they extend outwards
and backwards to any distance so that when their ends are pressed on the ground
by the raising of the lever handle they not only stop the progress of the machino
but prevent it from upsetting.
The prongs may be connected by a crossbar for strength which may be made in
such form as to increase the efficiency of the brake.
The ends of the prongs may be straight curved or of any other form or may be
furnished with castors or shoes.

An Improvement in Бісустев.
ALEXANDER DE ROUGEMONT, Birchfield, Addlestone, Underwriter, Lloyds, 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:-
The invention consists in the combination of a ground brake and support
adapted for ladies or gentlemen's machines.

Sheet 1. A forked lever AB extending for a short distance behind the hind
wheel to a point approaching the front of the frame between the legs of the rider
and easily reached by his hand. On the front of the seat standard and between
the top and bottom frames a quadrant shaped ratchet CD is fixed vertically. A
spring pawl in the interior of the lever A B at F controlled from the handle end
engages with the teeth of the ratchet CD and keeps the lever A B fixed at the
height desired; the forward or handle end of the lever A B is hollow and in one
piece until it reaches the ratchet where it is slotted so as to embrace this and
thence the lever spreads out into two prongs F E, F E, as in Sheet 1, Fig. 2
one on either side of the hind wheel. These prongs are pivotted on the axle of
the hind wheel or on studs fixed to the frame near the latter, or in some analagous
way or position, and afterwards they extend outwards and backwards to any
distance so that when their ends BB are pressed on the ground by the raising of
the lever handle A they not only stop the progress of the vehicle but prevent the
machine from upsetting. At B the prongs may be connected as in Sheet 1,
Fig. 2, if necessary, by a cross bar for strength, which may be made of such
a form as to increase the efficiency of the brake. The ends B B of the prongs may
be straight, curved, or of any other form, or may be furnished with castors,
wheels, or shoes.
The above being principally applicable for gentlemen-riders the following is
to be substituted for lady-riders. Sheet 2 Fig. 4 is an elevation of a lady's
bicycle showing the invention. The two parallel levers AB, AB rigidly con-
nected by cross bars as in Sheet 2 Fig. 6 are pivotted on the axle of the driving
pedals or otherwise and extending from a convenient point on the frame of any
bicycle toward the lower part of the hind wheel.
A stirrup DE pivotted on a clamp G fixed to the lower part of the frame em-
braces the two levers. To this stirrup and on the side of the machine which
shall prove most convenient a pedal F as in Sheet 2 Fig. 7 is attached to actuate
the levers through the stirrup. The action of the brake is as follows. Directly
the rider wishes to stop his bicycle he removes his foot from the driving pedal and
places it on the pedal F and pushes the latter forward. The ends AA of the
levers are so shaped that when the stirrup is thus pushed forward the bar E of the
stirrup pressing against the lower surface of the cam-shaped heads of the levers,
forces them upwards until it reaches its highest point, which is so calculated that
the lower ends BB then press on the ground. At this juncture the bar E of the
stirrup passes round the end of the lever and the latter is locked. The bicycle
is now supported on either side and the rider can remain at rest without getting
down. To start again a simple kick downwards is given to the stirrup and the
levers are released; they are brought back to their original position by the
action of a spring placed between them and the bottom bar of the frame at a
convenient point somewhere behind the stirrup.
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:
1. The combination of the levers AB pivotted on the frame and operating by
the lever substantially as described and shown in Sheet 1 Fig. 1.
2. In a lady's or gentleman's bicycle: The combination of the levers AB

page_text: pivotted on the frame and actuated by the stirrup DE through the brake pedal F
and forming together a new method of stopping and supporting bicycles, sub-
stantially as described and shown in Sheet 2 Fig. 4.
