PROVISIONAL SPECIFICATION
Improvements in and relating to Brakes and Locking Devices
for Wheeled Structures.
We, GEORGE ALDERMAN, Storekeeper, Selby Park, Birmingham and JAMES
WILLIAM SAVILLE, Patternmaker 1 Selby Terrace, Selby Park, Birmingham do
hereby declare the nature of this invention to be as follows:-
It relates to brakes for cycles perambulators and other wheeled structures and has
for its chief objects:
1st to check the speed of cycles when in use.
2nd to lock cycles and other wheeled structures as a safeguard against tampering
or interference.
3rd to lock perambulators and childrens vehicles when left unattended.
In carrying out one modification of this invention in connection with a cycle,
a spring controlled ram or brake is fitted sufficiently near the tyre of the front wheel
to be pressed upon or withdrawn from some part of it by the turning of a moveable
device adjacent to the steering handle and operating the said brake by means of a
moving sleeve, slots, pins, and other devices contained within the hollow handle bar.
This handle bar and its stem, connecting it to the fork of the front wheel, is
somewhat in the form of the letter T and hollow. A pulley, bell-crank or other
fulcrum lever is fitted within this hollow handle bar and connected, through its
vertical part to the brake and through one side arm thereof to a moveable device or
knob for manipulating the aforesaid devices. After this brake is applied the knob
can be taken away like a key leaving the cycle locked.
The devices for manipulating the brake comprise one. or more tubular sleeves
and diaphraghin partitions straight and semi-spiral slots with centre rod, chains,
cords, links, and pins for travelling in slots: à removeable handle or knob with
key hole slot, and peg to fit in spiral slot-one of these slots receives a pin
projecting from the centre rod; and when this brake is not applied to the wheel,
the knoh, by preference projects beyond the handle grip, the spring for operating
the brake holding the knob tightly within a catch, but when it is applied the
knob, or its shank, retires partially within the hollow handle bar forcing in the centre
rod and its projecting pin which is connected as beforenamed to the spring brake and
allows the pressure of that spring to press the brake upon the wheel: When this
operating rod is thus forced back to its utmost extent the manipulating knob can
be withdrawn leaving the end of the centre rod out of sight and reach within the
hollow sleeve devices and beyond ordinary reach of mischievous persons.
Corresponding letters, marks or other devices upon the knob and sleeve or sleeves
indicate the position or attitude in which to insert the knob. The brake is made
variously as a pad, wheel or grip, to engage with either the tyre, tyre cover or its
metal channel. It is sometimes attached in part to the prongs of the forks as
guides. If the pressure is against the metal tyre channel the action of the knob
and manipulating devices is slightly different to and reverse from those above

page_text: described the spring being strained or otherwise when the brake is taken off, and
the centre rod being drawn outwards when the brake is applied, a locking collar
ring or other device preventing the retiral of the brake rod when the knob is
taken off.
Another modification of this invention comprises a brake and operating devices
corresponding materially with those already described, enclosed within a tube or
covered way and fitted upon a perambulator, mail cart, childs carriage or other
wheeled structure for the purpose of locking one of its wheels or axles and
preventing the vehicle running away when left unattended upon sloping ground or
any such vehicle or structure being used without authority.

Improvements in and relating to Brakes and Locking Devices
for Wheeled Structures.
GEORGE ALDERMAN, Storekeeper Selby Park Birmingham and JAMES WILLIAM
SAVILLE, Pattern Maker, 1 Selby Terrace, Selby Park, Birmingham, 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:
..
It relates to brakes for cycles perambulators & other wheeled structures, &
has for its chief objects
1st to check the speed of cycles, when in use.
2nd to lock cycles, & other wheeled structures as a safeguard against tampering
or interference.
3rd to lock perambulators & children vehicles when left unattended.
In carrying out one modification of this invention, in connection with a cycle, a
spiral spring or a lazy tongs contained within a spiral spring controls a ram or
brake, which is sufficiently near to the tyre of the front wheel, to press upon the
india rubber tyre or cover or draw the brake, with pressure of the aforesaid springs to
the metal rims, or channel-or withdraw from some part of it-by the turning of a
movable device adjacent to the steering handle, & operating the said brakes by means
of a moving sleeve, slots, pins & other devices contained within the hollow handle
bar. This handle bar, & its stem connecting it to the fork of the front wheel, is
somewhat in the form of the letter T & hollow-A pully-rolling pin, bell-crank,
or other fulcrum lever is fitted within this hollow handle bar & connected through
its vertical part to the brake & through one side arm thereof to a movable device or
knob for manipulating the aforesaid devices. After this brake is applied the knob
can be taken away like a key leaving the cycle locked, or the knob is made a fixture.
The devices for manipulating the brake, comprise one or more tubular sleeves &
diaphragm partitions straight & semispiral slots with centre rod, chains, wire, cords,
links ratchet & spring & pins for travelling in slots; a removable handle or knob,
with key hole slot, & peg to fit in spiral slot or slide, one of these slots receives a pin
projecting from centre rod-or the handle, or knob, is detained.
When this brake is not applied to the wheel, the knob, by preference projects
beyond the handle grip, the spring for operating the brake holding the knob
tightly within a catch-but when it is applied the knob-or its shank, retires partially
within the hollow sleeve, for forcing in the centre rod, & its projecting pin which is

page_text: connected as before named to the spring brake & allows the pressure of that spring
to press the brake upon the wheel. When this operating rod is thus forced back to
its utmost extent the manipulating knob can he withdrawn, leaving the end of the
centre rod out of sight & reach within the hollow sleeve devices & beyond ordinary
reach of mischievous persons.
Corresponding letters, marks, or numerals, or secret signs or other devices
upon the knob or sleeve or sleeves, indicate the position or attitude in which
to insert the knob. The brake is made variously as a pad, wheel, or grip, to engage
with either the tyre, tyre cover, or its metal rim or channel. It is sometimes
attached in part to the prongs of the fork as guides. If the pressure is against the
metal rim or channel the action of the knob, & manipulating devices is slightly
different to & reverse from those above described, the spring being strained or
otherwise, when the brake is taken off & the centre rod, being drawn outwards,
when the brake is applied, a locking.collar; ring or other device preventing the retiral
of the brake rod when the knob is taken off..
Another modification of this invention comprises a brake & operating devices
corresponding materially with those already described, enclosed within a tube or
covered way & fitted upon a perambulator, mail cart, childs carriage, or other
wheeled structure for the purpose of locking one of its wheels or axles & preventing
the vehicle running away when left unattended upon sloping ground or any such
vehicle or structure being used without authority. It is understood the locking
devices may be used on the handle bar, at both ends-with such guides as may be
required.
In order that our invention, may be fully understood, we will more particularly
describe it, with the aid of the accompanying drawings,
Fig. 1. represents our invisible brake, in section, within the hollow handle bar, &
its stem connecting it to the fork of the front wheel. The brake is shown, out of
action, by spring e, compressing the lazy-tongs, but a turn of the knob p, outwards,
expands the lazy-tongs, c, & the brake g, is, applied to the tyre, to check the speed
of the bicycle, or the handle knob, is locked, by the device b, & the brake is
immovable.
Fig. 2. represents a section, of our brake, in elevation in the hollow head, or the
stem connected with the fork of the front wheel, of the machine, showing the brake, g,
in action, & clipping the metal rim, of the wheel, & lazy-tonga e expanded
actuated by wire d, which is worked by the knob p on the handle bar, at Figure 1.
Fig. 3. represents part in section & part in elevation of the handle which works
the invisible brake, inn & out of action. The end E. E. of the tube is attached to the
inside of the hollow handle bar, the knob p revolves on the tube of the locking bar
at q. upon the knob is fixed the semispiral slot i, also the wire d, its end is
fastened, at the small hole, in the knob. (The knob is shown in position, as in
Figure 1, with the lazy-tongs c closed, & the brake g out of action, & the locking bar
not locked, & the semispirl slot within the sleeve.) If, the knob is turned, or
drawn outwards the semispiral slot i abuts on another semispiral slot, in the sleeve v,
& the action of the knob pulls the wire d, which opens the lazy-tongs, & the brake
is pressed on tyre also the locking bar with its ridges jare drawn under rings b with
the numerals set them & the brake is locked-& the machine may be safely left,
unattended with its handle thereon.
Fig. 4. represents a sectional view, of the tubular sleeve, u, to be fitted inside the
handle bar, with removable knob & plan of its key hole ' which passes over
lug k on the rod n, & the knob pulls the rod, which holds the brake out of action,
&is pressed by spring m, & the teeth go into the collar, or ring, or the knob is
taken off & the rod is pressed by spring a & the brake is locked, & the enrl of rod is
out of the reach of mischievous persons. Similar parts are marked with like letters
of reference in the figures of the drawing-a handle bar, b secret device rings,
e lazy-tongs, d cord or wire or rod, e spring fastened to lazy-tongs & tube, rod,
or ram of brake, g brake, h guide wheel pulley, for cord to work on, i semispiral
slot on knob to work brake in & out of action, revolving on secret lock rod, jį ridges

page_text: upon the lock rod, for locking devices of the rings, k projection on end of rod,
to go through key hole, key hole, on plan of knob-whereby the knob is taken off-or
put on, reinovable knob, m spring to press on central rod, with the ratchet teeth, & to
hold the same in position, n central rod, p fixed knob on lock rod, but revolves
thereon, q joint of knob & lock rod, lock rod, s spring on central rod, u the
hollow sleeve, v semispiral section, in the sleeve.
Having now particularly described & ascertained the nature of our said
Invention, & in what manner the same is to be performed, we declare that
what we claim is-
1st. The arrangement & combination of the various parts as described &
illustrated in Figure 1 of the accompanying drawings.
2nd. The arrangement & combination of the various parts as described &
illustrated in Figure 2 of the accompanying drawings.
3rd. The device of the spiral spring & lazy tongs as set forth described &
illustrated in the accompanying drawings for the use upon a brake of a bicycle or
other vehicle.
4th. The locking device of letters, numerals, or secret signs-for the use upon the
handle bar of the brake of a bicycle-or other vehicle, to prevent such being used by
a person or persons not authorized.
5th. The detached arrangement of the knob as shown in Figure 4 for the purpose
set forth.
6th. By devices we lock the brake on the wheel without removing the handle, &
leave the machine unattended..
