I WILLIAM OSMONDE VENN, of Higher End, Hale, Salisbury, in the County
of Wiltshire, Farmer do hereby declare the nature of this invention to be as
follows:-
My invention relates to an improved brake for cycle wheels, and as for its object
to arrest or brake the progress of the machine without the said brake pressing upon
any part of the pneumatic or other tyre of the wheel.
My invention consists of a pair of suitably shaped arms, pivotally mounted upon
a pin or rod, after the manner of a pair of shear arms, the said pin or rod, being
suitably connected to, and fixed upon, the tube of the front or steering fork of the
machine, in such a position, that the lower ends of the said arms, when closed
together by the closure of their upper ends, grasp the wheels at both sides of the
rim, below and clear of the elastic tyre, the said lower ends of the said arms being
padded with rubber or other resilient material to prevent rupture of the japan
upon the wheel.
The upper ends of the said arms are pivotally connected to the one end of a pair
of levers, the opposite ends of which are jointly and adjustably connected to the
lower end of a vertical rod passing upwardly, through a suitable carrier, fixed
upon the said front fork tube, the upper end of the said vertical rod being pivotally
connected to the usual brake lever, in such a manner, that the usual manipulation
of the lever serves to raise the said rod and so close the said padded arms or jaws
upon the wheel rim, and so brake the speed of the machine. The said vertical rod
is held normally in its lowest position, and the said padded jaws open to their
widest extent, by the tension of a suitable spiral or other spring.

I, WILLIAM OSMONDE VENN of Higher End, Hale, Salisbury, in the County
of Wiltshire, Farmer 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 an improved brake for cycle wheels, and has for its
object to arrest or brake the progress of the machine, without the said brake
pressing upon any part of the pneumatic or other tyre of the wheel to the detriment
of the same.
For the purposes of enabling my invention to be more clearly understood I have
hereunto appended a sheet of drawings, in which:
Fig. 1 is a view showing the front elevation of so much of a bicycle, tricycle or

page_text: the like, as is necessary to illustrate my invention, which is shewn in its ille or
normal position affixed thereto, as hereinafter explained.
Fig. 2 is a side elevation of Fig. 1.
Fig. 3 is a view similar to Fig. 1 but showing my invention in the operation of
braking the wheel and arresting the progress of the machine.
My invention consists of a pair of arms such as A, A', of any suit ible light an
strong material, but preferably metal, curved outwardly at their lower enls a, a',
and have fixed upon their inner or opposing faces pads of rubber, rubber
composition, or other resilient material A,, the said arms A, A' being pivotally
mounted upon a pin or rod c, after the manner of a pair of she ir arms, the sail
pin or rod being connected to, and fixed upon the lower end of the front or steering
fork B of the machine (shewn more clearly in Fig. 2.) in such a position, that
when the lower ends a a¹ of the arms A. A', are brought together by the closure
of their upper ends, the said pads, grasp the wheel at both sides of the rim C,
below, and clear of the pneumatic or other tyre D.
of a
The upper ends of the said arms A, A' are pivotally connected to the one ends
of another pair of arms or levers E, E', which in turn, have their upper en is
jointly and adjustably connected at e to the lower and widened end of a vertical
rod F, which passes upwardly through a slot in the lower and bent end
suitable carrier or guide G, the upper end of which is arranged to form a spring
clip g', which embraces the upper end of the said fork and is retained in position
thereon by the means of a screw bolt, or its equivalent passing through holes in
the ends of the said clip g' as shewn in Fig. 2. The upper end of the said rod F
is forked or bifurcated at F", (as shewn at Fig. 2) which receives, and has
pivotally connected thereto, the centre or thereabouts of a brake lever J, one end
of which is pivotally connected to a collar K, arranged to slide upon the handle
bar L, which provides, that the usual manipulation of the said lever serves to
raise the said rd F, thereby imparting an upward pull by the pin e upon the
arms E and E, which bring together the lower euls of these, and the upper and
lower ends of A, and A', and consequently the pads and 4, the latter e nbracing
the rim C of the wheel D, as shewn in Fig. 3, and so braking or arresting the
progress of the machine.
The said rod F has a shoulder, and above this anl below the portion g of the
carrier G is surrounded by a spiral spring M, the tension of which serves to lower
the said rod when the lever Jis released, thus again expanding the arns A, A
and releasing the brake, and returning the braking apparatus fron the positi
shewn in Fig. 3 back again to its idle or normal position, or that shewn in Figs. 1
and 2.
The lower end of the vertiual rod F below the shoulder f, is exten led in
width to form a plate F in which is formed a number of holes f, at suitable
distances apart, these being to enable the pin e to be placed in such one of the said
holes as may be most convenient according to the length of the fork B of the
machine. I wish it understood that I do not confine myself to the exact shape
and configuration of the several parts of my invention as shown in the drawings but
may modify these to accommodate machines of different makes and other conditions
without departing from the principle set forth.
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.
In an improved brake for cycle wheels the combination of a rol such as F
carried in a guide such as G,, fixed upon the steering fork B of the inchins by
a clip such as g', the upper end of the aid rud being pivotally conaset: 1 to a
brake lever such as J, connected to the handle bar L at K, the lower end of the
said rod F, being connected to a plate such as F1 having holes for a ljustably
receiving a pin or stud e pivotally connecting the upper en ts of a pair of arms or
levers E and E, pivotally connected at their Iwer cost the upper eats of a

page_text: pair of arms or levers A and A', pivotally mounted upon a bolt or pin c connected
to the steering fork B, the said arms A, A' being bent or curved at a and a¹ and
carry resilient pads b, b, arranged to grip the sides of the rim C of the wheel,
when the rod F is raised by the lever Jas at Fig. 3, or to part clear of the said
rim by the tension of a spring such as M when the lever J is released as at Figs. 1
and 2, substantially as and for the purposes herein described and shewn.
