I, WENTWORTH HARRISON, of 10, Sussex Place, Onslow Square, South Ken-
sington, in the County of Middlesex, Hair Dresser, do hereby declare the nature of
this invention to be as follows:-
:-
The combined action of foot and hand power to front wheel the foot power is
given by placing the feet on rests, so placed that pressure of same acts upon the
rim of wheel. For the hand power I use a cat gut by means of a lever attached
to the handle bar this lever also contains a case for holding a gentlemens card at
the same time giving two tensions to cat gut one more power than the other.
I also use a tension to further tighten this gut worked by means of a left handed
thumb screw and to which the end of the gut is secured, the same can be worked
by a right handed thread, but preference is given to the left hand thread.
T construction of this rim brake is as follows
A, A horizontal bar bolted to bottom stay of any ordinary machine brake or on
the crown of forks.
B are bars shaped and formed with foot rests and the rubber of brake and
pulleys.
C is the rubber.
D the coil spring throwing the rubber off the wheel when the lever is set at
liberty.
E the cat gut.
F the adjustment worked with left hand thread in the form of a thumb screw.
G the lever to which is attached a case to hold a gentlemens address card.

Foot and Hand Rim-brake suitable for Velocipedes.
I, WENTWORTH HARRISON, of 10, Sussex Place, Onslow Square, South Ken-
sington, in the County of Middlesex, Hair Dresser, 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 a new or improved brake for velocipedes and refers
more particularly to that class of brake taking effect upon the rim of the wheel,
the said brake being designed to be operated by hand or foot power, while by the
Price 8d.1

page_text: particular form of construction employed, I am enabled to produce a very powerful
and emcient brake of few and simple parts.
In order that my invention may be fully understood I will now proceed to
describe same with reference to the accompanying drawings in which rig. 1 is a
front elevation, partially in section, illustrating the essential features of the brake
as applied to a velocipede.
Fig. 2 is a side elevation of the brake apparatus detached, and
Figs. 3 and 4 are detail views.
This new or improved brake comprises two side arms or levers a a pivoted
within a horizontal cylindrical case 6 upon pins c passing through the hollow
right angled arms a' of the levers a. The arms or levers a are connected by means
or the arms d secured to pins e e projecting therefrom, to a common operating
rod f, passing through the hollow cylindrical case y contained within the tubular
head of the machine, the bottom of the said cylindrical case 9 being expanded
as shown at g¹ for the purpose of preventing it passing completely into the tubular
head of the machine.
The operating rod f is screw threaded as shown, and carries at its lower
extremity a plug or nut j, between which and the top of the hollow cylindrical
chamber g
spiral spring is arranged, designed to normally force down the said
operating rod f and to keep the arms or levers a a in the position shown and out of
contact with the rim of the wheel.

m
The upper screw threaded extremity of the operating rod f carries a disc or
washer that can be adjusted to any required position thereon and
the said disc or washer one extremity of a flexible connection p
is made fast in any convenient and suitable manner, the said flexible connection
then passing through a small tube p¹ let into the handle bar stem
and pro-
jecting any required distance therefrom, so that upon the said flexible connection p
being drawn taut the operating rod f is raised bringing the extremities of the
arms or levers a a, which are furnished with small brake rollers r of any suitable
material, into contact with the rim of the wheel, thereby applying a brake to
same, while the said arms or levers a a also carry at their extremities projecting
plates upon which foot pressure may be applied for bringing the brake into
action.
In order that the flexible connection may be drawn taut when required, the
free extremity is firmly secured in any convenient and suitable manner to the
handle bar s, while to the said handle bar is also pivoted a plate s¹ upon the bolt
or pin which passes through the arm of the plate s¹, and into the handle bar
where it is rigidly secured, the lower edge of the plates (Figs. 3 and 4) is grooved
as shown (Fig. 4) and normally rests on the flexible connection p as shown so that
upon turning the plate into the position shown in dotted lines (Fig. 3), by means
of the handle or operating arm, the flexible connection p is drawn sufficiently
taut for raising the operating rod f so as to bring the extremities of the arms or
levers a into contact with the rim 1 of the wheel.
The brake may be secured in any convenient and suitable manner to the
machine but preferably by means of a small screw bolt designed to pass through
the projecting eye arranged on the crown of the front forks of a velocipede and
through which the ordinary brake rod passes, and to screw into the bottom of
the horizontal cylindrical case 6, while the tubular arms a¹ of the arms or levers a
pass between the crown plates one upon each side of the fork stem and are united
at the back by a plate w secured in place by nuts y, and in this manner the brake
is further secured in position.
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 new or improved brake for velocipedes comprising the arms or levers a

page_text: pivoted within a horizontal cylindrical case b, carrying brake rollers r; and an
operating rod secured to the arms or levers a a by the arms e, the whole retained
in the forward or inactive position by means of a spiral spring k contained within
a cylindrical case g arranged within the head of the machine and bearing against
an adjustable plug or nut j, and operated by the drawing taut of a flexible con-
nection such as p passing through a tube and secured to an adjustable washer
or disc m, the whole combined, arranged and operating, substantially as herein
described and shown with reference to the accompanying drawings and for the
purposes specified.
2/. The combination with a brake such as above claimed, of foot plates such as 13
to allow of the brake being operated by foot pressure, substantially as herein
described and shown.
3/. The combination with a brake such as above claimed of a plate s¹, the
arm of which is pivoted at s² to handle bars and which can be turned into the
position shown in dotted lines (Fig. 3) by means of the handle or operating arm v
for the purpose of drawing the flexible connection p taut for applying the brake;
substantially as herein described and shown with reference to Figs. 3 and 4 of the
accompanying drawings and for the purposes specified.
