page_text: We, ALBERT ERNEST LYON, of 179, Bethnal Green Road, London, General
Dealer, and NOAH THORNING, of 477, Bethnal Green Road, London, Manufacturer,
do hereby declare the nature of this invention to be as follows:-
This invention relates to improved brake apparatus applicable to cycles and
other vehicles fitted with wheels having inflated tyres and designed to be applied
to the wheel-rim in lieu of to the wheel-tyre.
The invention is characterized by the employment in such apparatus of an
opposite pair of laterally disposed brake-block levers or holders, which, normally,
are automatically maintained out of operative position, and, when the brake is
required to be applied, are caused by hand-actuated connections and in the
improved manner hereinafter described to apply the brake-blocks to the opposite
sides of the wheel-rim.
The brake-block levers are pivotally connected to a bracket secured to the
vehicle-frame, and are fitted with brake-blocks adapted to engage with the vehicle
wheel-rim, and are adapted to engage with a hand-actuated brake-rod and to be
actuated thereby as hereinafter described so as to cause the brake-blocks to be
applied laterally to opposite sides of the wheel-rim, a spring or springs serving
to restore the brake-rod connections and the brake-block levers to and to retain
them in their normal inoperative positions when released from the control of
the hand.
The upper arms of the levers may be thrust apart so as to cause the brake-
blocks to be applied to the sides of the wheel-rim, by a turning movement of the
brake rod about its axis acting through a cam piece, applied to its lower part, the
lower arms of the levers being connected by a spring normally tending to main-
tain the levers out of operative position and serving to return them thereto after
having been in action, or, by forming the cam piece with slots, both movements
of the levers can be positively effected by the rotative movements of the brake
red which may be effected by its upper part being twisted and by the end of the
hand lever being correspondingly slotted to engage with the twisted end of
the rod so that the reverse movements of the hand lever will reversely rotate the
brake rod.

We, ALBERT ERNEST LYON, of 179, Bethnal Green Road, London, General
Dealer, and NOAH THORNING, of 477, Bethnal Green Road, London, Manufacturer,
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 improved brake apparatus applicable to cycles and
other vehicles fitted with wheels having inflated tyres and is designed to be applied
to the wheel rim in lieu of to the wheel tyre.
The invention is characterized by the employment, in such apparatus, of an
opposite pair of laterally disposed brake block holders or levers, which, normally,
are automatically maintained out of operative position, and when the brake is
required to be applied, are caused by hand actuated connections to apply the
brake blocks laterally to the opposite sides of the wheel rim, as hereinafter more
particularly described with reference to the accompanying drawings.
On the drawings;-
Fig. 1, is a front elevation of the improved apparatus as applied to the steering
fork and steering wheel of a rear driven pneumatically tyred cycle, showing the
brake apparatus out of action;
Fig. 2, is a like view, showing the brake apparatus in action;
Fig. 3, is a side elevation;
Fig. 4, is a front elevation of a modification;
Fig. 5, is a sectional elevation of another modification;
Fig. 6, is a sectional plan on A--B, Fig. 5; and
Fig. 7, is a like view to Fig. 6, of a further modification.
a, a, represent the pair of oppositely arranged brake block holders or levers,
which are pivotally connected, at a¹, to a bracket, b, which, by clips and bolts, 61,
are rigidly connected to the crown of the steering fork, c, in front of the latter.
The lower arms of the levers are branched apart and shaped to embrace the
pneumatic tyre, d, and wheel rim, c, opposite which latter the levers are fitted
with brake blocks, a², formed of facings of leather, rubber or other suitable
material secured to metal carrying plates which are adjustably connected to the
levers by screw pins, engaging with slots, a', or otherwise in any convenient
manner, or, the brake blocks may be fixedly connected to the levers in any
convenient manner.
The upper arms of the levers are adapted to be operated by the ordinary brake
rod and connections so as to cause the brake blocks to be applied to the sides of
the wheel rim when the brake rod is actuated by the pressure of the hand in an
ordinary manner, and to be released from bearing against the wheel rim by the
action of the spring which returns the brake rod and its attachments to their
normal positions when released from the pressure of the hand. To this end, the
upper arms of the levers, «, may (Figs. 1, to 3,) each be formed with an inclined
slot, adapted to be engaged by a pin, f, projecting from arms, f¹, carried by
the brake rod f2, the lower end of which is inserted in a slot, 3, in the bracket, b,
which guides its movements and is encircled by a spring f³, which tends to main-
tain the brake rod and the lever arms, a, and the brake blocks in their normal
positions, ride Fig. 1. When it is required to apply the brake, the brake rod is
actuated by the hand lever, g, in an ordinary manner, and causes the levers to
apply the brake blocks to the sides of the wheel rim, vide Fig. 2.

page_text: Or, (Fig. 4,) the upper arms of the levers, a, may be pivotally connected to a
pair of toggle levers, h, pivotally connected, at h¹, to the brake rod, f2, or, (Figs. 5,
and 6,) the upper arms of the levers may be thrust apart so as to cause the brake
blocks to be applied to the wheel rim by a turning movement of the brake rod
about its axis acting through a cam piece, i, applied to its lower part, in which
event, the lever arms may be connected by a spring j, normally tending to
maintain the levers out of operative position and serving to return them thereto
after having been in action, or, by forming the cam piece, i, with slots, 1, (Fig. 7,)
both movements of the levers can be positively effected by the rotative movements
of the brake rod, which may be effected by its upper part, f, being twisted and
by the end of the hand lever, g, being correspondingly slotted to engage with the
twisted end of the rod so that its up and down movements will reversely rotate
the brake rod.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
In brake apparatus for cycles and other vehicles fitted with wheels having
inflated tyres, in combination, an opposite pair of laterally disposed brake block
levers pivotally connected to a bracket secured to the vehicle frame and fitted
with brake blocks adapted to engage with the vehicle wheel rim, a hand actuated
brake rod adapted to engage with the brake block levers so as to cause the brake
blocks to be applied laterally to opposite sides of the wheel rim, and a spring or
springs serving to restore the brake rod connections and the brake block levers to
and to retain them in their normal inoperative positions when released from the
control of the hand, as set forth.
