page_text: I, HAROLD HEGINBOTTOM ANDREW, of 165 Plymouth Grove, Manchester in the
County of Lancaster, Gentleman, do herely declare the nature of this invention to
be as follows:-
The considerable lateral projection of the handle bars of bicycles is a frequent
source of inconvenience, particularly in their carriage by railway, and in their
storage.
My Invention is designed to obviate this inconvenience and for this purpose I
hinge each handle bar, preferably as near as convenient to the centre of the
machine, in such a manner that the handle bars may be folded approximately
parallel with the vertical plane of the machine when out of use, and in such a
manner also that when the machine is in use, the hinges are locked, so that the
haudle bars cannot fold accidentally.
A convenient, but not the only method which I may employ in carrying out
my Invention, is to cut the handle bars transversely so as to completely sever
them at a short distance from the head, and cut away so much of the newly exposed
ends as will permit the subsequent folding of the bar. Having already prepared a
tube or rod with a hinge at its centre, and with such a diameter as to fit in the
exposed tubular ends of the handle bar, 1 insert one end of the hinged tube or rod
into one of the exposed ends of the handle bar, and the other part of the handle
bar is then placed upon the other end, and both are fixed by pinning or by brazing
or the like. Before making the joint I have arranged upon one part of the
severed handle bar, a sleeve which should fit thereon only just so easily as to permit
it to be slided. After the joint has been made, the sleeve is slided over it and
locks it rigidly until the sleeve is again removed. The sleeve may be secured by
various means such for example as by screw threads engaging it with the handle
bar, by a bayonet or similar joint, or by other suitable means.
I have described the method of constructing the hinge for one handle bar alone,
but it will be understood that both handle bars are or may be treated in the same
manner. The described process has reference to existing machines, and it will be
understood that in constructing new machines a different method of arriving at a
similar result may be employed.

page_text: Street, Coventry, in the county of Warwick, Cycle Manufacturer, 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.
The considerable lateral projection of the handle bars of bicycles is a frequent
source of inconvenience, particularly in their carriage by railway and in their
storage.
My present Invention has been designed to obviate this inconvenience, and for
this purpose I hinge each handle bar as near as is convenient to the central vertical
piane, of the machine, in such a manner that the handle bars may be folded
approximately parallel with that plane of the machine when out of use, and in
such a manner also that when the machine is in use, the hinges are locked so that
the bandle bars cannot fold accidentally.
A convenient, but not the only method which I may employ in carrying out my
Invention is illustrated by the accompanying drawings in which Figure 1 repre-
sents part of the handle bars and handle bar stem of a bicycle in elevation; and
Figure 2, the same in plan. I out the handle bars B, transversely so as to
completely sever them, at a short distance from the head. I then fit into the
exposed ends of the handle bars short tubes or bars each of which is provided at
its central part with a hinge or folding joint such as is shewn at J, both the hinge
or joint and the tube or bar of which it forms part being of uniform circular
cross section. I have found it more convenient to construct the hinged part from
round bar steel having the same diameter as the handle bar, and to reduce each
end of the jointed har for about an inch in length or more, to such a diameter that
it will fit correctly within the tubular bar, where it can be secured by pinning,
brazing, or other known means. Before securing the hinged or jointed part into
the exposed.ends of the handle bar, I slip upon the outer part of the handle bar, a
tubular sleeve S, which should fit thereon only just so easily that it may be freely
slided and turned over the jointed part. After the joint has been made, the
sleeve can be slided over it, as shewn to the right in the Figures, when the joint
will be securely locked with the handle bar in its rigid position as in use.
The sleeve S may be secured by various means such for example by screw
threads engaging the sleeve with the handle bar, by a bayonet or similar joint or
by other suitable means. At present, I prefer to employ the simple means illus-
trated by the drawings. Near the inner end of each sleeve I form a comparatively
short slots, and near to the head H, a short pin P, in such a position that when
the sleeve is pushed close to the head, the pin can come within the slot. To enable
the pin to enter the slot, I bulge or raise a part of the metal of the sleeve botween
the slot and the end, so that this bulged part can pass over the top of the pin.
This bulged part A, can advantageously be produced near to one end of the slot.
If, after the bulge has passed the pin, a slight turning movement be given to the
sleeve, the latter cannot then be moved longitudinally, and the joint is securely
and firmly locked.
In the Figures, I have shewn the joint open to the left, and closed to the right.
A short pin may be let into the outer part of the handle bars at C, to prevent the
sleeve dropping down the handle bar when the latter is folded down."
The described method for the construction of the joints has reference to existing
machines, and it will be understood that in the construction of new handle bars,
a different method of construction may be employed to arrive at the same result.
Having now particularly described my said Invention and in what manner
the same is to be performed, I declare that what I claim is:-
1. In the handle bars of bicycles, a folding joint and sleeve the latter of which
can be moved and secured over the joint and be withdrawn therefrom, constructed
and arranged substantially as hereinbefore described and as illustrated by the
accompanying drawings.

page_text: 2. Folding handle bars for bicycles, constructed and arranged substantially as
hereinbefore described and as illustrated by the accompanying drawings.
