Improvements in or relating to Brakes for Bicycles, Tricycles, Motor
Cars, and the like.
JOHN WAKEFIELD, 138, Saint Albans Villas, Robin Hoods Chase, Nottingham,
Engineer and Inventor, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in brakes. It has for its object the
improved construction and arrangement of such whereby the brake for the most
part may be concealed and applied by a new method, that is, a small lever which
answers two purposes, that is, by it the brake is applied, furthermore one or more
concealed steel cords or bands are adjusted to suit the height of the handle-bar
according to the requirements of the rider.
In carrying out the invention a small hand lever is arranged at or
near the end of the handle-bar. To the longer end of the lever
To
the hand is applied when it is desirable to stop the machine.
the short end of the lever a concealed steel cord or cords, or a steel band or bands
are connected by being passed through a simple form of clip arrangement, the ends
of the cords or bands are then turned back again in opposite direction and passed
through a second hole and along the inside of the handle-bar thus concealing
them. The communicating cords or bands are arranged all along the inside of
one side of the handle-bar and down the handle-bar stem and through the front
fork of the machine. A guide truck or pulley is arranged inside at the top of the
handle-bar stem by means of this pulley or truck a change of direction is obtained
to the communicating cords or bands as described. A clip is fastened on the
fork crown and may be shaped so as to able to carry a lamp. A lever is arranged
on the clip. To the longer end of this lever what is known as a spoon or friction
pieces are arranged, to the short end of the lever the ends of the communicating
cords or bands are connected. Thus it will be seen that by the movement of the
small hand lever herein before described the communicating cords or bands are
drawn up the inside of the front fork and along the handle-bar thus applying the
spoon or friction pieces to the tyre of the machine and so overcoming the motion
of the same.
For keeping the spoon or friction pieces off the tyre when the brake
is not in use a wire or other suitable spring is arranged on or near the clip fastened
on the fork crown. If it is desirable to use a rim brake, that is, a horse shoe
shaped casting having friction peices arranged thereon, which upon the brake
being applied brings the same in contact with the rim, then the lever herein
before described as being arranged on the clip at the fork crown is not required
because in this case a direct pull up only is required. If it is desirable to apply
this principal of applying the brake, to a band brake, that is to say this kind of
hand lever and communicating cords or bands, it is done by arranging the same
or a similar lever as the one upon which the spoon or friction peices are arranged
and herein before described. The band is then arranged along the fork blade and

page_text: underneath a drum or pulley which is fastened to the front wheel hub. The top
end of the band is connected to the lever just described. Thus it will be seen
that by the movement of the hand lever herein before described the band is
applied to the drum or pulley and the motion of the machine overcome. The
brake is intended for the front wheel but it may also be used on the back wheel
or driving axle.
A small stop collar is arranged on the handle-bar stem to prevent the handle-
bar from dropping when the same is slackened off and turned half round so as to
take up less room when the machine is at rest or stored. This may be done with-
out damage to the brake.
This brake has several advantages.
One very important advantage is the use of a new form of lever for applying the
brake and adjusting the same to suit the height of the handle-bar according to the
requirements of the rider, at the same time concealing the brake for the most part
and thereby combining the advantages of both outside and concealed brakes and
doing away with the disadvantages.
Improvements in or relating to Brakes for Bicycles, Tricycles, Motor
Cars, and the like.
JOHN WAKEFIELD, 138, Saint Albans Villas, Robin Hood's Chase, Nottingham,
Engineer, 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 brakes. It has for its object the
improved construction and arrangement of such wherby the brake for the most
part may be concealed and applied by a new method that is a small lever which
answers two purposes that is by it the brake is applied furthermore by it one or
more concealed cords or one or more steel bands are adjusted to suite the height
of the handle-bar according to the requirements of the rider. In carrying out
the invention a small hand lever is arranged at or near the end of the handle-bar.
To the short end of the lever a steel cord or cords or a steel band or bands are
connected by being passed through a simple form of clip arrangement that is,
a hole under the screw at c Figs. 1 & 5, No. 1 Sheet, the ends of the cord or cords
or band or bands are then turned back again in an opposite direction and passed
through a second hole and along the inside of the handle-bar thus concealing them.
The communicating cord or cords or band or bands are arranged all along the
inside of one side of the handle-bar and down the handle-bar stem of the same
and through the front fork of the machine. A guide tube is arranged up the stem
of the handle-bar or a truck or pulley may be arranged at the top of the handle
bar stem by these means a change of direction is obtained to the communicating
cords or bands as described. A clip is fastened on the fork crown and can be
shaped so as to be able to carry a lamp and a lever is arranged on the clip to the
longer end of this lever what is known as a spoon or friction pieces are arranged
and to the short end of the lever the ends of the communicating cords or bands
are connected, thus it will be seen that by the movement of the hand-lever before
described the communicating cords or bands are drawn up the inside of the front
fork and along the handle-bar thus applying the spoon or friction-pieces to the

page_text: tyre of the machine and so overcoming the motion of the same. For keeping the
spoon or friction pieces off the tyre of the machine when the same is not in use a
wire or other suitable spring is arranged on or near the clip fastened on the fork
crown. If it is desirable to use a rim brake that is a horse-shoe shaped casting
having friction pieces arranged thereon which upon the brake being applied brings
the same in contact with the rim then the lever herein before described as being
arranged on the clip at the fork crown is not required because in this case a direct
pull up only is required. The ends of the before mentioned casting, fit in guides,
which may be part of the foot rests, or be separate pieces arranged on the fork-
blades in a similar way to the foot rests. For keeping the brake off the rim when
the same is not in use two small springs are arranged. If it is desirable to apply
this principal of applying the brake to a band brake (that is to say this kind of
hand lever or communicating cords or bands) it is done by arranging the same or
a similar lever as the one upon which the spoon or friction pieces are arranged and
herein before described, the band is then arranged along the fork blade and under-
neath a drum or pulley which is fastened on the front wheel hub, the top end of
the band is connected to the lever just described thus it will be seen that by the
movement of the hand lever herein before described the band is applied to the
drum or pulley and the motion of the machine overcome. The brake is intended
for the front wheel, but it may also be used on the back wheel or driving axle.
In accordance to the Patent Laws and that my invention may be better under-
stood I now proceed to explain the drawings sent herewith. Fig. 1 is a section of
handle-bar with hand-lever and connections for communicating motion to the
brake and adjusting communicating band fixed at end of handle. Fig. 2, is a
section of handle-bar stem shewing pulley or truck by which a change of direction
is obtained to the communicating band. Fig. 3 shews communicating band
attached to lever for operating the brake direct. Fig. 4 is a front view of brake
bracket and Fig. 5, shews the handle bar attachment reversed and placed at the
other end of the handle proper. Fig. 6, is a front view of the rim brake. Fig. 7,
is a section of handle-bar stem shewing guide tube by which a change of direction
is obtained to the communicating band. A is the brake lever fulcrumed at B
and provided with a short arm C over which the communicating band D passes
inside the handle-bar and over the truck or guide pulley E on Fig. 2, downwards
to the lever F Fig. 3, and connected at G which forms a short arm F the lever F
is fulcrumed at H and the longer arm as attached to it a spoon or friction pieces I.
J is a spring for raising the friction pieces off the wheel. In Fig. 3, K is a clip
fastened to the fork crown:-the brake bracket L and its connections can be raised
or lowered by means of the screw M provision being made for same by a series of
holes arranged vertically. Ample provision is made for raising or lowering of
the handle-bar by the extra length of the communicating band D as shewn in N
Fig. 1 and 5. Fig. 6 is a front view of the rim brake O being the horse-shoe
shaped casting P is the footrests or separate pieces arranged on the fork blades
and acts as a guide to the casting 0. Q is the spring for keeping the rubbers R
off the rim when not in use D being the connecting band. Fig. 7, is a section of
the handle-bar stem and S is the guide tube for obtaining a change of direction
to the communicating band D. T is a spring for keeping the guide tube in its
place. This brake has several advantages, one is a new form of lever for applying
the brake and adjusting the same to suite the height of the handle-bar according
to the requirements of the rider at the same time concealing the brake for the
most part. A second advantage is the use of the guide tube which answers the
purpose for which it is intended better than any other known means. The third
advantage is the way the rim brake is arranged.
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:
1
First. A new form of lever as described and shewn in the drawings, by which the

page_text: brake is applied also a perfect outside adjustment of the communicating cord is
obtained by the same lever.
Second. A Guide tube as described and shown in the drawings.
Third. A rim brake as described and shewn in the drawings.
