An Improved Locking Device, particularly adapted for Locking
together the Adjustable Parts of Cycles.
I, SAMUEL ALLEN, of Stratford Villas, Heaton, in the County of Northumber-
land, Engineer, do hereby declare the nature of this invention to be as follows:-
-
This invention relates to an improved device for locking together two con-
centrically arranged members having independent rotary or longitudinal move-
ment, the said device being particularly adapted for locking together the adjustable
parts of cycles.
The invention comprises one or more small blocks or clutch pieces mounted in
radial slots in the outer of the two members the said blocks or clutch pieces—
the inner or operating faces of which are preferably provided with serrations or
their equivalents-adapted to engage with corresponding serrations
or their
equivalents in the outer surface of the inner member, and of an operating ring
adapted to be mounted on the outer member over the radially arranged blocks or
clutch pieces and having inclined planes or their equivalents on its inner surface
adapted to engage with the said blocks or clutch pieces when the ring is rotated
and so force them inwards and cause them to engage with and lock the inner
member to the outer member.
To disengage the parts the ring is turned in the reverse direction which either
acts to withdraw the blocks or clutch pieces or gives them room to be withdrawn
by means of suitable springs acting on them.
This device is particularly well adapted for locking the adjustable cups of ball
bearings to the cases thereof after adjustment and also for locking the handle bar
pillar to the socket of the steering head for the purpose of locking the steering
head and so prevent the machine being ridden.

An Improved Locking Device, particularly adapted for Locking
together the Adjustable Parts of Cycles,
I, SAMUEL ALLEN, of Stratford Villas, Heaton, in the County of Northumber-
and. Engineer, do hereby declare the nature of this invention and in what
Price S11

page_text: manner the same is to be performed to be particularly described and ascertained
in and by the following statement:-
This invention relates to an improved device for locking together two con-
centrically arranged members having independent rotary or longitudinal move-
ment, the said device being particularly adapted for locking together such parts
of cycles.
In the accompanying drawing which shows-by way of illustration-some uses
to which this device can be applied :-
Figures 1, 2, 3, 4 and 5 art views showing the application of the invention to
a ball bearing head for the purpose of forming a steering lock, being an example
of locking together two members having independent rotary movement.
(Figures 4 and 5 are sectional views in plan showing the lock inqeraive and
operative respectively).
Figures 6, 7, 8 and 9 are views showing the application of the invention to ball
bearings for the purpose of locking the adjustable cup or cone, being an example
of locking together two members having both independent rotary and independent
longitudinal movement.
Throughout the views similar parts are marked with like letters of reference.
Referring to Figures 1, 2, 3, 4 and 5. In the upper edge of the cup A of a
ball bearing head are cut or formed two radial slots in which are mounted small
blocks or clutch pieces having their inner faces toothed or serrated to adapt
them to engage with a toothed or serrated flange & formed on the adjustable cone B
of the ball bearing head, and adapted to fit down within the cup A, the said
cene B being mounted on the handle bar stem.
"
The blocks or clutch pieces u are preferably mounted on small plate springs C
the ends of which engage with the exterior of the cup A and act to keep the
toothed or serrated faces of the said blocks or clutch pieces clear of the teeth or
serrations of the flange of the cone B. Encircling the cup A is a loose ring D
preferably having a milled edge to enable it to be readily turned by hand. In this
ring are two recesses for the blocks or clutch pieces to lie in. The inner face
of the ring is chamfered away from one edge of each of the recesses d to form
inclined planes so that by rotating the said ring the blocks or clutch pieces are
forced inwards thereby causing them to grip the flange of the adjustable cone and
thus securely fix together the two parts of the steering head, forming a perfect
lock.
A channel is formed round the inner face of the ring C to receive the ends
of the small springs C.
Although I have referred to two blocks or cluteb pieces it will be obvious
that there may equally well be either only one such block or clutch piece or
three or more of them.
Referring to Figures 6, 7, 8 and 9 which shows this invention applied to the
adjustable cone of a ball bearing. The toothed or serrated flange is formed on
the adjustable cone B as shown by Figure 8, and the blocks or clutch pieces a
are mounted in slots in the case X of the bearing as shown by Figures 6 and 7.
The operating ring takes the form of a cap D as shown by Figure 9 and it is
provided for a part of its depth with an internal screw thread adapting it to be
screwed on to the case X of the bearing which is provided with an external screw
thread to receive it as shown by Figure 7.
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). An improved locking device for fixing together two concentrically arranged
parts, consisting of one or more blocks or clutch pieces mounted in radial slots
in the one of the parts, of a flange on the other of the parts, with which the
blocks or clutch pieces engage, and of a ring encircling the blocks or clutch

page_text: pieces and adapted on rotation to force the blocks or clutch pieces inwards until
they grip the flanged part, as and for the purpose set forth.
(2) An improved locking device for fixing together two concentrically arranged
parts, consisting of one or more blocks or clutch pieces having toothed or serrated
inner faces uiounted in radial slots in the one of the parts, of springs carrying
the blocks or clutch pieces and adapted to so engage the part in which the blocks
or clutch pieces are mounted so as to force them outwards, of a toothed or serrated
flange on the other of the parts, with which the blocks or clutch pieces engage,
and of a ring encircling the blocks or clutch pieces and having recesses to receive
the blocks or clutch pieces and inclined planes on its inner surface whereby its
rotation forces the blocks or clutch pieces inwards so that they grip the toothed or
serrated flanged part, as and for the purpose set forth.
(3) A steering lock for velocipedes, constructed arranged and adapted to
operate, substantially as herein described and illustrated by Figures 1, 2, 3, 4,
and 5 of the accompanying drawing.
(4) A device for locking the adjustable cones of ball bearings, consisting of
spring controlled blocks or clutch pieces such as a having toothed or serrated inner
faces mounted in radial slots in the case X of the bearing, of an adjustable cup
or cones such as B having the edge badjacent to its outer face toothed or serrated
for the blocks or clutch pieces to engage with, the said cone being adapted to b
threaded into the case of the bearing in the usual manner, and of a cap such as 1)
adapted to be threaded on to the exterior of the case X of the bearing and having
recesses such as with inclined edges adapted to fit over and engage with the
blocks or clutch pieces a, as set forth.
