any direction required leaving front wheel in same position.
FURTHER EXPLANATION.
A universal cup locking joint constructed in two parts viz. male & female.
The male part is on the upright stem of handle bar, and the female inserted in the
horizontal handle bar. The female part is cup formed, in the interior of the cup
are deep cut threads but the threads do not continue the circle of the interior that
is two sides each occupying a quarter of the circumference of the cup are threaded
and the other two quarters are left plain that is the thread is cut away. The male
part is made with threaded and plain sides to correspond with the female part. The
two parts to form the joint are slipped one into the other the plain parts or quarters
in or on either allowing passage for the threads to pass without being screwed in.
A quarter turn of the handle bar brings the threads into locking position & the
handle bar into position for riding and perfectly rigid. The rigiduess &
position being held by a small spring or catch inserted in a slot cut in the shoulders
of the two said parts.
An Improved Handle-bar for Cycles.
We, CHARLES CRAIG, of 2, Coborn Road, Bow, Manager to Builders' Merchants,
and EDWARD SIDNEY JOHNSON, of 15, Broxbourne Road, Forest Gate, Commercial
Officer, both in the County of London, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement:-
Our invention relates to a universal cup locking joint in the upright stem of a
handle-bar forming a joint for connecting the upright stem and handle-bar together

for convenience of storage or transit. The said oup locking joint is to be released
by a spring or catch, and the handle-bar turned in any direction required leaving
the front wheel in the same position..
And in order that our invention may be thoroughly understood, we now proceed
to describe the accompanying drawing thereof; reference being had to letters and
figures marked thereon.
Fig. 1 is a plan of the top of the male screw a and flange h.
Fig. 2, is a vertical section of the female socket or cup which is brazed in the
hollow of the handle-bar so that when the handle-bar is in position for riding
no joint is seen.
Fig. 3; is an elevation of Fig. 2.
In carrying our invention into practice we form a universal cup locking joint
constructed in two parts viz.male and female. The male part a is on the
upright stem of handle-bar c and the female part inserted in the horizontal or
handle-bar c. The female part d is cup formed and in the interior of the cup are
deep cut threads e, but the threads.do not continue the circle of the interior that is
two sides each occupying a quarter of the circumference of the cup d are threaded
and the other two quarters y are left plain that is the thread is cut away. The male
part a is made with threads i and plain sides j to correspond with the female part.
The two parts to form the joint are slipped one in the other, the open plain parts
or quarters in or on either side allowing passage for the threads to pass without
being screwed in. A quarter turn of the handle-bar brings the threads into locking
position and the handle-bar into position for riding and perfectly rigid, the rigidness
and position being held by a small spring or catch k inserted in a slot cut in or
near the shoulders of the two said parts.
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:
In a handle-bar for cycles, the combination of the universal cup locking joint in
the upright stem of the handle-bar forming a joint and upright stem for connecting
together with a small spring or catch inserted in a slot to secure the whole rigidly
together substantially as herein described and according to the accompanying
drawing.
