PROVISIONAL SPECIFICATION.
A Combined Backpedalling Brake Clutch, Crank Shaft Lock and Ball-
head Steering Lock for Cycles and the like.
We, JOHN HARRY TAYLOR, Mechanical Engineer, 190, Heneage Street, Bir-
mingham, and WILLIAM HABICHT, Mechanical Engineer, 29, Whateley Road,
Handsworth, Birmingham, do hereby declare the nature of this invention to
be as follows:-
This device is for it's purpose to operate a brake of any kind, on the rear wheel
of a cycle in connection with free wheel operated cycles, by means of back
pedalling, also, to be used as a locking arrangement on the crank shaft to pre-
vent the cycle from being ridden when left unattended, also, a locking arrange-
ment on the front fork steering column in the ballhead of the cycle frame, to
prevent the front wheel from swinging round when standing erect.
This device is concealed from view inside the tubes and bottom bracket of
the cycle frame.
A cycle so fitted with this combination device can be used firstly, the clutch
inside the bottom bracket is used to operate a brake of any kind by means of
clutch action by the reverse motion of the crank shaft.
Secondly, this same clutch device is used to lock up the crank shaft also by
clutch action, thus preventing the crank shaft rotating backward or forward.
Thirdly, the front fork steering column passing through the ball head of the
cycle frame is prevented from swinging round by means of a friction band
encircling it, the crank shaft lock, and ball head steering lock are operated by
means of a rod with a hexagon head on one end, passing through the top tube
of the cycle frame, and looking out between, and at the back of the seat pillar lug
of the cycle frame, by applying a key or spanner to this hexagon head of this
rod to turn it round, when both steering lock, and crank shaft lock are locked up
simultaneously without interfereing with the backpedalling arrangement of the
clutch inside the bottom bracket.
To explain this combination device clearly, we will firstly describe the clutch
inside the bottom bracket of the cycle frame. This clutch device consists of
one circular disc cut in halves in diameter across, drilled through the centre to
receive an ordinary crank shaft passing right through, this disc is encircled by a
threaded locking ring, on the inside periphery of this disc are cut two inclined
plane recesses, each inclined plane rising in opposite directions to each other, in
each inclined plane recess is placed a broad steel roller, the ends of which pro-
ject out on each side of the disc, the roller No. 1 is always directly bearing on
the periphery of the crank shaft by means of two spiral coil springs,
a double
one on each side attached to the ends of the roller, and to
between the disc
headed connecting rod pin, which passes through
and locking ring of the disc, thus retarding the backward motion of the crank
shaft, the other roller No. is always kept away from directly bearing on the
periphery of the crank shaft by means of two springs attached to both sides
of the disc, but, only brought to bear on the periphery of the crank shaft when

page_text: required to lock the crank shaft by means of a wire attached to both ends of the
roller, and passing right up the down tube of the cycle frame, and attached to
the rod which passes through the top tube of the cycle frame, it will be clearly
seen that when both rollers are bearing at the same time on the periphery of
the crank shaft, that the crank shaft cannot rotate backward or forward, but,
when No. 1 roller bears on the periphery of the crank shaft, and No. 2 roller
does not, the crank shaft is free to rotate in the forward motion.
Ballhead steering lock consists of a steel friction band encircling the front
fork steering column, the ends of this steel friction band are rivetted to a small
steel block No. 1, in the centre of this block No. 1 a hole is drilled, and threaded
to receive the end of the rod passing through the top tube in the cycle frame,
there is a small concave steel block No. 2, wedged between the front fork steer-
ing column and block No. 1, with a pivot hole also to receive the end of the rod
aforesaid, so it will be seen when the rod is screwed up, the friction band con-
tracts round the front fork steering column, and the steel concave block No. 2
causes compression, so by these means a tight wedge is formed round the front
fork steering column, thus preventing it moving round.
The seat pillar stem to be used to suit the requirements of this device is slotted
out on each side from the bottom, with an inner round liner telescoping inside,
in this liner is drilled a hole through both sides, the slots in the seat pillar stem
and the holes in the liner are intended for the rod that passes through the top
tube of the cycle frame to pass through.
There are two connecting rods passing through two holes drilled through the
bottom bracket of the cycle frame and fixed to the. clutch inside the bottom
bracket. There may be more rollers used in the brake clutch. We claim the
novelty of this combination device in this concealed form, even if done by any
other means.
The backpedalling brake clutch, and the crank shaft lock may be used without
the ballhead steering lock.

A Combined Backpedalling Brake Clutch, Crank Shaft Lock and Ball-
head Steering Lock for Cycles and the like.
JOIN HARRY TAYLOR, Mechanical Engineer, 190, Heneage Street, Bir-
mingham, and WILLIAM HABICHT, Mechanical Engineer, 29, Whateley Road,
Handsworth, Birmingham, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This device is for it's purpose to operate a brake of any kind acting on the
rear wheel of a cycle in connection with free wheel operated cycles, by means of
back pedalling, also to be used as a locking arrangement on the crankshaft to
prevent the cycle from being ridden when left unattended, also a locking arrange-.
ment on the front fork steering column in the ball head of the cycle frame to
prevent the front wheel of the cycle from swinging round when standing erect.
The steering lock and crank shaft lock acting simultaneously together, controlled
by a key or spanner.
This device is concealed from view inside the tubes, and bottom bracket of

page_text: the cycle frame. The object of this invention is that an any point backpeddlling
brake is acted on the rear wheel of a cycle fitted with a free wheel while in
motion, but when the cycle is left standing erect and stationary, the cyclist in
tightening his steering lock by means of a key or spanner, tightens the front fork
steering column from swinging round, also the forward motion of the crank shaft
is locked up simultaneously, thus preventing the cycle from being ridden when
left unattended, or from being stolen.
A cycle so fitted with this combination device can be used firstly. The roller
clutch device fitted on the crank shaft (Z) inside the bottom bracket is used to
operate a brake of any kind on the rear wheel of a cycle, by means of a roller
clutch action, by the reverse motion of the crank shaft (Z). Secondly, this same
roller clutch device fitted on the crank shaft (Z) inside the bottom.bracket, is
used to lock up the forward motion of the crank shaft (Z) by roller clutch action.
Thirdly, the front fork steering column passing through the ballhead of the
cycle frame is prevented from swinging round by means of a steel friction band
The crank shaft lock and ballhead steering
encircling it, when tightened up.
lock are operated and controlled by a key or spanner being applied to the hexagon
head (A) of the pin or rod (A B C D) Fig. 1, of the steering lock mechanism,
when both the front fork steering column, and the forward motion of the crank
shaft (Z) are locked up simultaneously without interfering with the backpedalling
brake acting on the rear wheel of the cycle.
The steering lock mechanism in the ballhead, and the roller clutch mechanism
inside the bottom bracket controlling the forward motion of the crank shaft (Z),
are connected together by means of a wire and the like connection (L), passing
up inside the down tube, from the bottom bracket to the special bottom ballhead
lug Fig. 2, direct, at an angle of 65 degrees or so from a line of the ball head of
the cycle frame. The bottom ballhead lug Fig. 2 being of a special design to
suit the requirements of this combination device, having a top tube extension
tube (A), wherein runs the hexagon headed pin or rod (A B C D), operating and
controlling the steering lock, and the crank shaft lock.
To explain this combination device clearly, we will firstly describe the roller
clutch device inside the bottom bracket of the cycle frame, this roller clutch
device consists of one circular disc cut in halves (W and X) in diameter across,
drilled through the centre to receive an ordinary crank shaft. (Z) passing right
through, this disc (W and X) is encircled by a threaded locking ring (Y), on
the inside periphery of this disc (W), are cut two incline plane recesses (aa)
and (b), in each incline plane recess is placed a broad steel roller (No. 1 and
No. 2), the ends of which project out on each side of the disc (W), the steel
roller (No. 1) is always kept directly bearing on the periphery of the crank
shaft (Z) by means of two spiral coil springs (U), one of each side, attached to
the ends of steel roller (No. 1), to connecting pin (V) on disc (W), thus retarding
the backward motion of the crank shaft (Z) when the backpedalling brake is
applied, the other steel roller (No. 2) is always kept away from directly bearing
on the periphery of the crank shaft (Z), by means of two spiral coil springs (0),
joined to ends of steel roller (No. 2), and to connecting pin (T) on disc (X), but
only brought to bear on the periphery of the crank shaft (Z) by means of a wire
and the like connection (L) being attached to both ends of steel roller (No. 2), and
passing right up the down tube, from the bottom bracket, to the special bottom
ballhead lug Fig. 2, direct, at an angle of 65 degrees or so from a line of the ball-
0 head of the cycle frame, and attached to the drum part (C) of the pin or
rod (ABCD), which passes through the top tube extension tube A of the special
bottom ballhead lug Fig. 2, it will be clearly seen, that when both steel rollers.
No. 1 and No. 2 are bearing at the same time on the periphery of the crank
shaft (Z), that the crank shaft (Z) cannot rotate backward or forward, but, when
5 steel roller (No. 1) bears on the periphery of the crank shaft (Z), and steel
roller No. 2 does not, the crank shaft (Z) is free to rotate in the forward motion.
The working of the steering lock, and crank shaft lock, are accomplished by a

page_text: key or spanner being applied to the hexagon head (A) of the pin or rod (A B C D),
on being turned round the wire and the like connection (L), winds round the
drum part (C) of the pin or rod (A B C D), thus drawing No. 2 steel roller up
the incline plane (a a). There are two brake connecting rods Q passing through
two holes drilled through the bottom bracket, for an attachment to be made for
a brake of any kind acting on the rear wheel of the cycle, these brake connect-
ing rods (Q) are attached to brake connecting rods pin (P). There
two spiral coil springs (R), one encircling each of the brake
connecting rods (Q) on the outside of the bottom bracket. There are
two felt washers (S), fitted one to each brake connecting rod (Q), fitted between
spiral coil springs (R), and the face of the bottom bracket, on the outside of the
bottom bracket, to keep the dust, and mud from entering the bottom bracket by
the holes through which the brake connecting rods (Q) pass.
are
Ballhead steering lock consists of a steel friction band (G), encircling the front
fork steering column, the ends of this steel friction band are screwed by screws (H)
to steel block (E), in the centre of this steel block (E), a hole is drilled and tapped
through, to receive the threaded end (1) of the pin or rod (A B C D) passing
through the top tube extension tube (A), of the special bottom ballhead lug
Fig. 2 of the cycle frame, there is a small concave steel block (F) wedged between
the front fork steering column, and the steel block (E), with a pivot hole to
receive the end (D) of the pin or rod (A B C D) to engage in, so it will be seen,
when the pin or rod (A B C D) is screwed up, the steel friction band (G) con-
tracts round the front fork steering column, and the steel concave block (F)
causes compression against the front fork steering column, so by these two
means a tight wedge is formed round the front fork steering column, thus pre-
venting the front fork steering column from swinging round.
We hereby describe the working principle of the various working parts of this
combination device in detail Fig. 1 (A B C D) being the rod or pin of the steer-
ing lock in one solid piece of metal, passing through the top tube extension
