PROVISIONAL SPECIFICATION.
Improvements in Velocipedes.
I, WILLIAM MORRIS MORDEY, of the Victoria Works, Lambeth in the
County of Surrey, Electrician, do hereby declare the nature of this invention to
be as follows:
My invention relates to brakes for velocipedes of the kind in which the brake-
shoe or spoon is normally kept out of contact with the tyre by a spring or
equivalent and is pressed upon the tyre by the foot of the rider when it is desired
to apply the brake.
The object of my invention is to provide a brake of this kind which shall be
powerful, compact and at the same time simpler than those heretofore constructed.
In one form of brake according to this invention the brake shoe or spoon is carried
by an arm secured or clamped to one leg of the fork and extending laterally
beyond the other leg so as to form a foot piece giving a convenient hold for the
foot when applying the brake. This arm may be flexible and of the nature of a
spring, or it may be pivoted or jointed and acted on by a spring, to keep the brake
normally out of action. When it is desired to be able to use both feet in applying
this form of brake, a second arm may be secured or clamped to the other leg of
the fork and extend across the same in the reverse direction to the first arm, so as
to also rest on the shoe and at the same time afford sufficient foothold for the foot
of the rider. Or the second arm may be constructed with a shoe in the same
manner as the first. This form of brake may be permanently secured to the
machine, or it may be secured in such a manner as to be readily detachable
therefrom when desired.
In another form of brake according to my invention the shoe or spoon is secured
to a short vertical stem working in suitable supports or guides and is acted on by
a coiled spring which tends to raise the shoe from the tyre. The shoe or spoon is
provided with two projecting foot pieces one on each side thereof, though in some
cases only one such foot piece may be provided. When the rider wishes to
apply the brake he presses with his fect on the aforesaid projections, thereby
overcoming the resistance of the aforesaid spring and causing the shoe or spoon to
press on the tyre.
For this
purpose I provide stops in proximity thereto against which they can be moved by
the feet, whereby they are prevented from applying the brake when being used
merely as rests.
I sometimes construct the foot pieces so as to serve also as foot rests.

Improvements in Velocipedes.
1, WILLIAM MORRIS MORDEY, of the Victoria Works, Lambeth, in the
County of Surrey, Electrician, 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 relates to brakes for velocipedes of the kind in which the brake-
shoe or spoon is normally kept out of contact with the tyre by a spring or

page_text: equivalent but can be pressed upon the tyre by foot pressure when the rider
desires to apply the brake.
The object of my invention is to provide a brake of this kind which shall be
powerful, compact, light and at the same time simpler than those heretofore
constructed.
In the accompanying drawings,
Fig. 1 is a perspective view showing one arrangement of my improved foot brake
with the adjacent part of the fork to which it is applied.
Fig. 2 is a front elevation to a larger scale of the brake detached.
Fig. 3 is a similar view to Fig. 2 showing a modified arrangement of the brake.
Figs. 4 and 5 are respectively a front and side view of an arrangement suitable
for use as a brake or as a foot rest as required, and
Fig. 6 is a detail view of a clip used in this arrangement.
Figs. 7 and 8 are views showing further modifications of foot brake according to
this invention.
Fig. 9 illustrates a modification wherein the brake is applied to the wheel rim
instead of to the tyre.
In the arrangement shown in Figs. 1 and 2. A is the brake shoe or spoon, which
may be of any convenient shape other than that shown, and which, in the case of
pneumatic tyres is preferably made say about four inches in length in order to
distribute the pressure on the tyre. This brake shoe or spoon (hereinafter referred
to as the spoon) is secured to a stem B arranged to work in a suitable guide or
bushing C fitted between projections D and secured in position by a bolt D*, or
otherwise arranged as may be convenient. The stem B is square, to prevent it
turning in the guide C though it may be round and be provided with a feather
for the same purpose. E is a coiled spring surrounding the stem B and inserted
between the guide C and a pin B* passed through the upper end of the stem.
This spring tends to raise the brake spoon A from the tyre. The said spoon is
provided with arms F carrying foot pieces G arranged one on each side. With
this arrangement when the rider wishes to apply the brake he presses with his feet
on the said foot pieces thereby overcoming the resistance of the spring E and
causing the spoon A to press on the wheel tyre below it. In some cases only
one arm F and foot piece G may be employed. The arms F themselves may be
so shaped as to serve as foot pieces.
,
In the arrangement shown in Fig. 3 the stem B is made hollow or tubular and
the spring E is arranged inside the same. A pin or bolt E passes through the
guide C and through slots in the stem B so as to support the lower end of the
spring, whilst allowing of the necessary movement of the stem. The upper end
of the stem is closed by a cap E' against which the upper end of the spring bears.
This cap is secured to the stem by a bayonet joint or otherwise so as to permit of
ready removal of the spring E for cleaning or renewal.
In the arrangement illustrated in Figs. 4, 5 and 6 wherein I adapt the brake to
serve also as a foot rest, the arms F are mounted on the stem B in such a manner
that they can turn thereon to a slight extent and in proximity to each of such
arms provide a stop H over which the corresponding arm can be brought by the
feet.
The stops will then prevent the arms moving downward and applying the
brake when being used. merely as rests. The stops H as shown more clearly in
Fig. 6 are each in the form of a clip, whose forward part projects sufficiently
beyond the fork H' to enable one of the arms F to rest. thereon, the said clip being
detachably secured to the fork by a set screw H². It may however be formed on
or otherwise fixed to the fork.
Fig. 7 shows another arrangement of foot brake constructed according to this
invention together with the adjacent part of the bicycle fork to which it is applied.
In this arrangement of brake the spoon A is carried by an arm F pivoted to a
bracket D secured to one leg of the fork H. The said arm.extends laterally
beyond the other leg of the fork and carries at its extremity as in the foregoing
arrangements a foot piece G. The arm F is acted on by a spring E that serves

piece the arm F can be depressed, and the
with the tyre.
By applying the foot to the said foot
spoon A be brought into engagement.
Instead of pivoting the said arm to a bracket as shown, it may be pivoted
directly to the fork of the bicycle, or it may be formed of flexible material so as
to itself serve as a spring to keep the brake normally out of action.
When it is desired to be able to use both feet in applying this form of brake,
the arrangement shown in Fig. 8 is adopted, in which in addition to the spoon,
pivoted arm, bracket, foot piece, and spring, shown in Fig. 7 there is a second
arm F, with foot piece G, that is pivoted to a bracket on the other leg of the fork,
or is mounted in any other convenient manner. Both arms extend across the shoe
in opposite directions the first mentioned arm being connected thereto, and the
second arm resting thereon. Thus the brake can be operated by either foot, or by
both feet as desired. The second arm may be if desired constructed with a shoe
in the same manner as the first. This form of brake may be permanently secured
to the machine, or it may be secured in such a manner as to be readily detachable
therefrom when desired.
Although I have hereinbefore described my invention as applied in connection
with a spoon brake, I may in cases where the wheel rim is suitably shaped, employ
a brake shoe so formed as to press on the wheel rim instead of on the tyre.
Such an arrangement is illustrated in Fig. 9 wherein the spoon is replaced by two
blocks A' of suitable material such as vulcanized india-rubber adapted to bear on
the outer edges of the wheel rim.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is
1. In a velocipede a foot brake comprising a brake shoe, an arm or arms with
foot pieces extending laterally thereof, and a spring for holding the said brake.
shoe normally out of action, such brake shoe being carried by a stem B acted on
by the spring and working in a guide C substantially as hereinbefore described
with reference respectively to and shown in Figs. 1 and 2 and in Fig. 3 or by an
arm or arms F as described with reference to and shown in Fig. 7 and in Fig. 8.
of the accompanying drawings for the purposes specified.
2. In a brake of the kind referred to in the preceding claim, the arrangement of
stops H in proximity to the arms F so as to enable said arms to serve at will as
foot rests substantially as hereinbefore described with reference to and shown in
Figs. 4, 5 and 6 of the accompanying drawings.
Dated this 8th day of March 1893.
