COMPLETE SPECIFICATION.
An Improved Locking Device, specially applicable to Cycle Steering
Mechanism.
We, JOSEPH HENRY HUGHES, of 28, Fentham Road, Birchfields, Birmingham,
in the County of Warwick, Works Manager, and GEORGE EDWARD ASTON, of
13, Witton Lane, Aston jurta Birmingham, aforesaid, Foreman, do hereby declare
the nature of our said invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:
Our invention has for its object an improved locking device which is specially
applicable for locking the steering head of a cycle and will be found to be very
effective and simple in construction.
In order that our invention may be clearly understood and more easily carried
into practical effect we have appended hereunto a double sized sheet of drawings
upon which we have shewn the application of our locking device to the steering
socket of a safety" velocipede.
"
Figure 1 is a side view of a portion of the steering socket of a safety with our
locking device applied thereto.
Figure 2 is an end view of Figure 1 shewing our locking device in the interior
of the lug socket.
Figure 3 is a part sectional plan view of Figure 1.
Figure 4 is a view of the steering socket tube shewing the hole through
which the locking device works.
Figure 5 is a view of the tube or socket in which the adjusting pin fits.
Figure 6 is a view of the adjusting pin.
Figure 7 shews an elevation and plan view respectively of the loose gripping or
locking piece.
In carrying our invention into practice we form two holes in a line with one
another in the sides of the branch socket al of the lug A into which one end of
the steering socket tube B fits. We then fit the case or cross tube into these holes,
a portion of the tube protruding into the interior of the steering socket and this
portion of the cross tube D is cut away at so as to conform with the interior
of the steering socket as clearly shewn at Figure 5. The end of this cross tube D
is enlarged so as to butt against the exterior of the lug A as shewn at Figure 2 and
in the interior of this end of the cross tube D we fix the spiral spring S one end of
which butts against the shoulder s¹. Fitted into the cross tube D is the adjusting
pin E which is reduced at the end and screw threaded to receive the thumb
nut and the portion of this pin when fitted into the cross tube which comes
opposite the cut away portion is also cut away in a similar manner as clearly
shewn at Figure 6. The steering socket tube B has the hole 61 formed in the end
of that portion which comes opposite the cross tube D and into this hole b¹ we fit
the lugs f of the loose gripping piece F as clearly shewn at Figure 7.
These lugs
fit loosely around the cross tube D so as to hold the gripping piece in position
as shewn at Figure 2. In order to lock the steering tube H which passes down

page_text: the steering socket the thumb nut 3 is tightened up by which means the pin E
is drawn forward until it presses against the gripping piece F thus binding this
gripping piece firmly against the steering tube H thereby locking it in any desired
position, but when the thumb nut is unscrewed the spring S draws the pin E
back into its normal position thus releasing the steering tube. The dome nut d
is provided at the end of the pin E so as to prevent the thumb nut 3 from coming
off the pin E.
It will be evident that our locking device may be applied either to the top lug
of the steering socket as shewn or to the bottom lug or we may fix our locking
device to both lugs if desired.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is: :-
CLAIMS.
First: The improved locking device consisting essentially of a cross tube such
as D with its spring S an adjusting pin such as E or its equivalent, a thumb nut
such as d or its equivalent, and a gripping piece such as F, all arranged in the
manner and for the purpose substantially as herein set forth and as shewn upon
the accompanying sheet of drawings.
Second Locking the steering tube of a cycle by a gripping piece such as F
actuated by a pin such as E working in a tube or socket such as D having the
spring S in the manner substantially as herein set forth and as shewn upon the
accompanying sheet of drawings.
Dated this 15th day of September 1898.
