Improvements in and connected with Brakes for Velocipedes and
other Chain Driven Vehicles.
HENRY ANSELL, Cycle Maker, 11, Canterbury Road, Brynmill, Swansea,
Glamorganshire, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in & connected with brakes for vehicles
& more particularly to bicycles, tricycles, & similar chain driven vehicles. It
is so arranged as to form a brake, footrest, & thorn-catcher. A clip is attached
to both fork sides to which footrest is fastened by a pin & nut. Two screwed
studs are secured to clip from which the brake blocks are worked by metal links
or straps & to which is fastened the thorn-catcher forming a bow over wheel
the whole being worked by a screwed or twisted plunger inside head of machine
& fastened to thorn-catcher. A tube slide which fits handle bar stem is tapped
to suit plunger & connected by a link and pin to brake lever in front or behind
handle bar & is worked by a slight downward pressure of the thumb. The
handle bar stem has a small slot through which a pin connects link from lever
to tube slide. The brake blocks which are made of leather, rubber or any other
suitable material work between fork sides & wheel & grips the rim underneath.
The brake can be fitted outside head same as ordinary brake, & still form a
combined brake, footrest, & thorn-catcher & can be worked on either front or
back wheels. In cases where rims have studs, wires, or where it is impossible to
use a rim brake, it can be used as a tyre brake, by transferring links or straps
on to the brake plunger rod inside head of machine working two rubber shoes
or blocks fixed to crown plates above wheel which act on tyre.

Improvements in and connected with Brakes for Velocipedes and
other Chain Driven Vehicles.
I, HENRY ANSELL, formerly of 11, Canterbury Road, Brynmill, Swansea,
in the County of Glamorgan, and now of S, Dellwyn Street, Swansea, afore-
said, Cycle 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 improvements in and connected with brakes for
velocipedes and other chain driven vehicles, and relates more particularly to
ดา

page_text: bicycles, tricycles and the like. It may be so arranged as to form a brake,
footrests, and thorncatcher combined. I may attach to each fork blade a clip, to
which the footrest may be fastened by means of a bolt and nut or the like,
or said clip and footrest may be made in one piece. Two screwed studs may
be secured to said clip from which the brake blocks may be worked by con-
necting links or straps and the thorncatcher which may connect both brake
blocks together, the thorncatcher being in the form an arch over the tyre. The
whole may be actuated by a plunger rod, which may work inside the head of
the machine and be fastened at its lower end to the thorncatcher.
A slide, say
in the form of a tube or rod, may fit inside the handle bar stem, and be screwed
or otherwise adapted at its lower end to receive the plunger rod aforesaid, and
may be connected by a link and pin to the brake lever in front of or behind
the handle bar, and may be worked by a downward pressure on the outer end
of the brake lever; or upward pull, according to the position of the fulcrum.
The handle bar stem may have a small slot in which may work the pin connecting
the inner sliding piece above mentioned to the link or links connecting same
to the brake lever. The brake blocks, which may be made of leather, rubber,
or any other suitable material, may work between the fork blades and wheel,
and bear on the underside of the rim. My improvement may be fitted outside
the head, if desired, similar to an ordinary brake, and still form a combined
brake, footrest, and thorncatcher, and may be worked on either front or back
wheels. In cases where the rims have studs, or where it is impossible or not
convenient to use a rim brake, I may suitably connect the plunger rod to the
extremities of the brake blocks through the medium of, say, short links, the
brake blocks working on a pin carried by a plate which may be secured to
the fork crown or fork itself.
In order that my invention may be more clearly understood I have attached
hereto a sheet of drawings, on which
Figure 1 shows a sectional elevation of the front or head of a bicycle, the
brake in this case being used on the rim, and
Figure 2 also represents a sectional elevation of the front or head of a bicycle,
but showing the brake applied to the tyre.
Similar letters refer to similar parts in both figures.
A shows the front fork, B the fork crown, C the fork stem, D the handle bar
and E its stem. The usual brake lever is shown by F attached to the handle
bar by a stud G and clip H, the inner end of the brake lever F being connected
by a link or links K to a pin L secured to the upper part of the piece M, which
is capable of sliding within the handle bar stem E. The plunger rod N, shown
screwed into the lower end 0 of the piece M, is connected at its lower end to
the thorn catcher P, which in turn is secured to the brake blocks Q. The clips R
have attached on the outer side the footrests S, and on the inner side, by means
of links T; the brake blocks Q. The wheel rim is shown by U and the tyre by V.
In Figure 2, W shows the links for connecting said plunger rod N to the
brake blocks Q, which latter may connect to links W by pins X, Y the pin
for connecting the links W to said plunger rod N, said brake blocks swinging
on a pin or the like %, carried by a plate a.
The working of my invention is as follows. Upon the outer end of the brake
lever F being depressed, the plunger rod N is caused to rise (through the medium
of the links K and sliding piece M, the connecting pin L traversing a suitable
slot (not shown on drawings) cut in the stem E The upward motion of the
plunger rod is transmitted through the thorn catcher P to the brake blocks Q,
causing them to come into contact with the under surface of the rim U.
Rigidity is given to the brake blocks Q by the links T.
When it is desired to apply my brake to the tyre instead of the rim of a
wheel (see Figure 2), I may pivot to the lower end of the plunger rod N two
short links W, pivotted at their lower ends to the brake blocks Q, which latter
may work on a pin or the like Z carried by a suitable plate a, which
may be

page_text: detachable, secured to the fork crown or blades; this plate a may also carry
footrests and thorncatcher, if desired. Upon the rise of the plunger N, the
links W are made to assume a more upright position and to approach one another
as also are the brake blocks Q which are thus made to bear on the tyre V.
The helical spring shown at b may be provided to return the brake to its
normal position upon the release of the pressure on the brake lever F, as above
mentioned.
For purposes of adjustment, the sliding piece M may carry a nut 0, or be
screw threaded at its lower end, so that the height of the plunger rod N, which
is intended to screw into the nut 0, may be varied, as desired, say, when the
handle bar is required to be raised or lowered.
The thorn catcher and footrests may be of any suitable well known form.
It is to be understood that my invention may be used wholly outside the head
of the bicycle or the like, instead of partly inside and partly outside, without
departing from the spirit of my invention.
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. The herein before described improvements in and connected with brakes
for velocipedes and other chain driven vehicles, consisting of brake blocks such
as Q in combination with an adjustable rod such as N bearing an arched spring
such as P, the latter acting both as a thorn catcher and a means of connection for
actuating said brake blocks.
2. Clips R for supporting footrests S and also the brake blocks Q, the latter
being pivotted and connected by arched thorncatcher P to plunger rod adjust-
ably mounted in sliding piece M, actuated from brake lever F, substantially as
described.
3. In brakes for velocipedes and other chain driven vehicles, a lever F con-
nected to brake blocks Q through the medium of link K, adjustable sliding
piece M, plunger rod N and links W, the latter being pivotted to a pin Z carried
by a plate a, the whole operating substantially in the manner hereinbefore
described with reference to Figure 2 of the accompanying drawings.
