HENRY BALFOUR, 35, Stockwell Park Crescent, Brixton, S.W., Clerk, do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the brake work of cycles and the
like.
In working out my invention relating to a rim brake, applied by a lifting
motion acting through the medium of a rod, wire, chain, or other means, or a
combination of the same, I have devised an attachment to the lower end of such
rod wire or the like lifting medium, consisting of two pieces of metal suitably
curved or otherwise shaped to clear the tyre, furnished at the lower extremities
with shoes, (A) Fig. 1) fitted or shod with leather, rubber vulcanite felt or the
like, or with any suitable combination of the same, designed to work upon a
bolt, stud or other bearing (shown in Fig. 8) projecting through a hole or slot
in or near their vertical and horizontal centres, such stud or bearing being fixed
or clamped to a suitable portion of the cycle such as the back stays, back or
bottom forks behind the bracket, or the front forks, and the levers kept on
such stud by a nut or other means.
The upper extremities of these said lever pieces are designed to be slotted at
or near their extremities, and to be held to the uplifting rod, wire or the like
by a bolt or rivet passing through the two slots as the ends overlap as shown
in (Fig. 2) or they may be made to cross each other and to be held in such
position and worked by and through a link or slotted attachment to the end of
the rod, wire, or the like, sliding past each other upon an upward lifting motion
being given to the lifting rod or the like as shown in Fig. 3, or they may be
made to overlap and to be attached either directly or by a connecting link or
links to the said rod wire or the like as shown in Fig. 4.
An alternative method is shown in Fig. 5. The shaped levers are slotted
at or near their vertical and horizontal centres in an inward and upward direc-
tion, and their upper extremities made to overlap and, by a bolt, rivet or the
like passing through them, made to connect with the lifting rod or the like.
The scope of my invention embraces
(a) The use of the shaped levers carrying shoes at their lower extremities
and having slotted upper ends.
(b) Such levers having a hole,-upward inward slot, or bearing at or about
their vertical and horizontal centres.
(c) A slotted link or attachment to the lower end of the lifting rod or the
like through which the upper extremities of the shaped levers shall slide.
(d) And also the stud or pivot attachment for the working of the said levers
upon, or any combination of these devices or arrangements ((a) (b) (c) (d)
above).
In all the aforesaid variations of my invention the action is:-
Upon a lifting motion being given to the rod, wire or the like, the lower
extremities carrying the shoes are made to impinge or grip upon the rim of the

page_text: wheel, thus retarding forward motion. The return of the shoes to their normal
position is effected by means of spiral or other springs, either at or near the
upper or lower extremities.
When used for the front wheel the shoes may be somewhat enlongated and
fitted with an end turning outwards on either side, and resting or catching
against the back portion of the front forks.
The power required to control the lifting motion may be applied by or
through, either a simple or compound lever, acting either by hand from the
handle bar, top bar or other suitable position or by a suitably designed foot
attachment.
A compound lever attachment has been designed to fix upon the top bar and
main down tube and to work either by an angle piece or by roller and chain in
conjunction with a rod wire or the like, either through a hole or slot in the seat
pillar or by a loop of wire or other material working round the seat pillar on
either side. Variation as in (Fig. 7), with toggle joint to levers is claimed.
Allowances may be made for variation in the size or shape of the lever pieces
of the brake, as found convenient for use with or without mudguards, or for the
front or back wheels.
Variation may be made in the form of the shoe which may be either let into,
brazed or rivitted upon the lever extremities, (see A Fig. 1) or made with a
top portion (E) intimately joined with the lever and a lower portion (F) in
Fig. 6, clamped or screwed or otherwise fixed thereto, carrying between them
the leather rubber or the like and allowing adjustment of the same by means
of slots through which the clamping bolts or the like work.

HENRY BALFOUR, 35, Stockwell Park Crescent, Brixton, S.W., Clerk, 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 improvements in the brake work of cycles and the
like.
In working out niy invention relating to a rim brake, applied by a lifting
motion acting through the medium of a rod, wire chain or other means, or
combination of the same, I have devised an attachment to the lower end of such
rod, wire, or the like lifting medium, consisting of two pieces of metal suitably
curved or otherwise shaped to clear the tyre, furnished at the lower extremities
with shoes, A Fig. 1 in drawings left with Provisional Specification, fitted or
shod with leather. rubber, vulcanite felt or the like, or with any suitable com-
bination of the same, designed to work upon bolts, studs or other bearings,
shown in Fig. 8, through a holes or slots in or near their centres, see D Fig. 1
and C Fig. 5 such studs or bearings being fixed or clamped to a suitable portion
of the cycle. such as the back stays, back or bottom forks, behind the bracket,
or the front forks, and the levers kept on such studs by nuts or other means
shown in Fig. 8 D¹.
The upper extremities of the said lever pieces are designed to be slotted at
or near their extremities, and to be held to the uplifting rod, wire or the like
by a bolt or rivet passing through the two slots as the ends overlap as shown

page_text: in a, a Fig. 1 and Fig. 2, or they may be made to cross each other, and to be
held in such position and worked by and through a link or slotted attachment
to the end of the rod wire or the like, sliding past each other, upon an upward
lifting motion being given to the lifting rod or the like, as shown in Fig. 3;
or they may be made to overlap, and to be attached either directly or by a con-
necting link or links to the said rod wire or the like, as shown in Fig. 4.
An alternative method is shown in Fig. 5. The shaped levers are slotted at
or near their centres, in an inward and upward direction as shown at C in Fig. 5
and their upper extremities made to overlap, and, by a bolt, rivet or the like
passing through them, made to connect with the lifting rod or the like.
The scope of my invention embraces
(a) The use of the shaped levers carrying shoes at their lower extremities
and having slotted upper ends.
(b) Such levers having holes, upward-inward slots or bearings at or about
their centres.
(c) A slotted link or attachment to the lower end of the lifting rod or the
like, through which the upper extremities of the shaped levers shall slide:-
(d) And also the stud or pivot attachments for the working of the said levers
upon, or any combination of these devices or arrangements (a) (b) (c) (d) as
above.
In all the aforesaid variations of my invention the action is:-
Upon a lifting motion being given to the rod wire or the like, the lower
extremities carrying the shoes are made to impinge or grip upon the rim of the
wheel, thus retarding forward motion. The return of the shoes to their normal
position is effected by means of spiral or other springs, either at or near the
upper or lower extremities.
When used for the front wheel the shoes may be made somewhat elongated, and
fitted with an end turning outwards on either side, and resting or catching
against the back portion of the front forks.
The power required to control the lifting motion may be applied by or
through either a simple or compound lever, by hand from the handle bar, top
bar or other suitable position, or by a suitably designed foot attachment.
Fig. 9 on the sheet left with the Complete Specification shows a method
which has been devised, in the form of a brake rod working in a clip, clamped
or otherwise fastened upon the handle bar, at a point beyond the centre thereof,
and passing round the back of the steering pillar, at which part the said lever
is rounded see H Fig. 9 allowing it to slide through a link, ring or other such
contrivance, to which is attached one end of the wire or the like lifting medium,
to the other end of which is attached the brake; or the brake rod may pass
through the wire suitably looped round it as shown in J Fig. 9.
A sliding collar shown in K, Fig. 10 has also been designed, encircling the
steering pillar, carrying one end of the wire, and being raised by the lifting
action of the brake rod aforesaid.
This brake rod may have a second piece bolted rivetted or otherwise fastened
to it, round the front of the steering pillar, as shown in L Fig. 11 seen in plan
to which front portion is attached a wire or other lifting medium, controlling
the action of the brake upon the front wheel also, by the same action; or the
brake rod may be made in one piece as shown in Fig. 12 encircling the steering
pillar, for the same purpose, or two separate levers may be used, one for each
wheel. The wire or other lifting medium may be made to work round the
necessary angles by means of suitably fixed rollers, working with or without
flexible chain at such angles, or by means of angle-levers, or by passing the wire
through tubular guides suitably fixed or ciamped upon the handle bars or other
necessary parts of the machine.
A variation, as shown in Fig. 7, with toggle joint to levers is claimed or
allowed for.
Allowances for variations in the sizes or shapes of the lever pieces of the

page_text: brake, as found convenient for use with or without mudguards, or for the front
or back wheels, or for any other contingent cause, may be allowed for.
Variation may also be made in the form of the shoes, which may either be
let into, brazed or rivetted upon the lower extremities, see A Fig. 1, or made
with a top portion intimately joined with the lever, and a lower portion, F Fig. 6,
clamped or screwed or otherwise fixed thereto, carrying between them the leather,
rubber or the like, and allowing for adjustment of the same, by means of slots
through which the clamping bolts or the like work. Or by fixing a wide or
other suitable piece of metal through or upon the shaped lever pieces, at their
lower extremities, and fixing the braking substance thereon, in the form of
blocks, washers, cones or other suitable shapes.
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) (a) The use of the suitably shaped lever pieces working upon studs or
bolts, through holes or slots at or near their centres, and with slotted
upper ends as shown in Fig. 2.
(b) The same lever pieces sliding through a link as shown in Fig. 3.
(c) The same levers over lapping and being drawn together by links or
otherwise at their extremities as shown in Fig. 4.
(d) The suitably shaped levers working by means of an expanding toggle
joint at their upper extremities, as shown in Fig. or any combina-
tion of the foregoing.
2. The use in combination with either of the above arrangements under
abcd Claim 1, of the suitably designed lever rod made to work round the
back of the steering pillar, and thus to allow for play in steering the machine,
substantially as described.
3. The use in combination with either of the above arrangements under
a b c d Claim 1, of the sliding collar upon the steering pillar, carrying one
end of the lifting wire, and being raised by lifting the said lever, working
either at the back or front of the steering pillar, and giving the same freedom
in steering, substantially as described.
4. The use in combination with either of the above arrangements under
abcd Claim 1, of the combination lever rod working back and front whee!
brakes simultaneously, substantially as described.
