PROVISIONAL SPECIFICATION.
An Improved Brake, applicable to Velocipedes or any Rubber or Soft
Tyres of Wheels.
HERMAN RICHARD WERNICK, Cycle Maker, 154, Walworth Road, London, S.E.,
and WILLIAM FREDERICK CHARLES WARD, Mechanic, 214, Vauxhall Bridge Road,
Victoria, do hereby declare the nature of this invention to be as follows:-
The one herewith described being designed for use on the front or on a rear
wheel of a velocipede. The essential parts being 1st the lever or actuating
movement. 2nd the connection or connecting rod from lever to brake. 3rd the
mechanical movement that is fixed to act near the periphery of a wheel. 4th the
general construction & arrangement of each different part and the whole of
the various parts when put together as a complete brake..
The actuating lever compose a lever attached to a plain or grooved cam or eccen-
tric, or the lever is so shaped that way, that its working result is the same as
follows, that when the lever is moved to operate the brake movement, the pull
or travel of the intermediate connection is decreased as the brake blocks or friction
rollers near the periphery of the wheel, & the pressure on the brake blocks being
increased, due to the extra leverage which is gained by the use of the eccentric
or cam.
The lever being mounted on a fulcrum & provided with clips for attachment
of same to framework & fitted to actuate & control the brake movement from
any suitable part of a cycle frame as preferred.
The connection for transmitting power to brake, consists of either a length of
chain, metallic tape, cord, wire, rod, or leather, or any suitable material may be
used, singly or in combination, & each or any of the above provided with a lock
nut or device for adjustment of length between the actuating lever & brake
movement.
The brake movement consists-clips for attachment to frame work by means
of two screwed pins or bolts, the heads or a portion of the same pins or bolts
projecting and serving as fulcrums & on each pin are mounted metal blocks, one
or both provided with a lover or arm to make connection to. And both blocks
having one or more projections engaging one with the other arranged to gear
together, so that when the arm is lifted the blocks turn in the same direction,
each block also carries an adjustable straight or bent wire or a fixed. leg, on the
extremites of each are fitted either brake blocks or friction rollers to engage with
& grip the periphery when the arm or lever is moved through the connection from
the actuating lever.
The whole of the above mechanism is held in its normal or inactive position by
means of a spiral or flat spring.

HERMAN RICHARD WERNICK, Cycle Maker, 154, Walworth Road, S.E. London,
WILLIAM FREDERICK CHARLES WARD, Mechanic, No. 9, Fernham, Road, Croydon,
S.E., late of 214, Vauxhall Bridge Road, 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:-
-
The essential parts of this invention being A the lever, B the connecting rod or
connection from lever A to C the mechanical movement of brake which acts on
the sides or periphery of the tyres of wheels.
The grooved eccentric lever A or the actuating part of brake is mounted on A2
by means of the shoulder screw 9 the head of same being cut away as shewn to
form stops for stud 10 on A to rest against the lever A being free to move between
the stops when mounted on shoulder screw 9 and attached to the frame work of
a cycle by means of the adjustable clip A 2.
Connection is made from A to the extended arm of C by a direct wire, rod, or
chain or combination, or a flexable cord fastened to the counter sunk screw in
the eccentric groove of A and the other end attached to C1.
The brake mechanism C comprising two shaped blocks 01 02 arranged to
gear to-gether when mounted on shoulder screws, 6, 7, on D-C1 being provided
with an extended lever or arm and on both C1 C2 are projections which gear
together so that if C1 is moved by its extended arm, C2 revolves similarly.
Inserted in holes in C1 C2 are adjustable legs 3 provided with friction blocks 4
and are so arranged that when adjusted to either the sides or the periphery of a
tyre may be locked by the set screw 5, the blocks are held C1 C2 in their normal
position by means of a tension spring attached to the pins 8, 8.
The clips D are attachable to a frame work of a cycle by shoulder screws 6 and 7
which also serve as the fulcrums for C1 and C2 to work on.
In reference to Sheet 2, Fig. 1 shews the various parts assembled together. A
being the eccentric lever (mounted on the handle bar or on any other convenient
part of a cycle, by means of the clip A2 Sheet 1) shewing the lever resting
against the stop on the head of shoulder screw in the position indicated by the
pull of the tension spring, through the connection B, which is attached to arm C 1.
The tension spring is sprung between & fastened to pins (see Fig. C Sheet 1)
and also keeps the legs 3 which carry the brake blocks 4, 4 apart, and free of
the tyre until such time as the lever A is depressed as shewn in Fig. 2, Sheet 2,
which causes the connection B to pull on the arm of C1 and C1, at the same
time actuating C2 causing the brake blocks to approach, and press upon the tyre
until the lever A is released, when the spring again pulls all parts back to their
normal position.
The mechanism of C is shewn mounted on the fork crown of a cycle by means
of the clip D, Sheet 1, as described
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare what we
claim is:-
1st. The application of the eccentric, grooved cam, eccentric drum or similar
motions to brakes or to levers used for operating brakes or like apparatus.
2nd. The application of a direct tension wire or rod from operating lever to
brake movement.

page_text: 3rd. The application of adjustable brake shoes, adjustable either to the peri-
phery or sides of tyres and the arrangement of each part and the whole of the
various parts when put together as a complete brake as described.
