Traveller, JAMES LLOYD COPPING, Brookside, Spencer Road, Wealdstone, Middlesex,
Engineer, do hereby declare the nature of this invention to be as follows:-
A handlebar with its vertical supporting stem, the bar being separate from the
stem and itself divided transversely (through the centre) into halves, so that either
half respectively is removable, adjustable and reversible.
Attached to the top of the vertical stem is a horizontal hollow socket forming
the crosspiece of a T, the stem forming the tail of the T.
This crosspiece varies in cross section, the two ends and the middle portion being
bored of larger clear area than the intermediate parts;--these intermediate parts
are bored of smaller clear area and may be bored a regular or irregular polygon or
round with keys or key-heds, the object being to provide projections to engage
with other projections on the handlebar. A longitudinal slot is formed running
from end to end of the internal circumference of each of the intermediate parts.
Each half handlebar (at its end farthest from the handle) is provided with a short
length, the outside shape of which corresponds with the intermediate parts of the
crosspiece described in the preceding paragraph; it is also provided with a small
fixed key or stop of such size as to pass through the slot above mentioned. Next to
the end piece on each half handlebar is a length of smaller cross section, and next
to this the usual bar and handle or "grip."
A spiral or other spring may be fitted in the bore of the crosspiece, this spring
to be in compression and tending to force both halves of the handlebar outwards.
Or two separate springs may be used, one for each half handlebar.
To attach either of the half handlebars the end is thrust into the bore of the
crosspiece until the end (polygonal or keyed) portion has passed through into the
central recess in the crosspiece, the small key or stop passing through the slot pro-
vided for it. The handlebar is then revolved until it is brought into the required
position and then drawn back until the polygonal or keyed end is engaged in the
corresponding part of the crosspiece, the small fixed key or stop (now out of line
with its slot) preventing the handlebar from drawing out, and the spring or springs
when inside the central bore of the crosspiece reducing lateral vibration or slip.

page_text: GEORGE DYSON TREECE, The Haunt, Greenhill, Harrow, JAMES LLOYD COPPING,
Brookside, Spencer Road, Wealdstone, Harrow, Engineers, 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 invention consists of a handle bar (A) with its vertical supporting stem (B)
the bar being separate from the stem and itself divided transversely through the
centre into halves so that either half respectively is removable adjustable and
reversible.
Attached to the top of the vertical stem is a horizontal hollow socket (C) forming
the crosspiece of a T, the stem forming the tail of the T.
This crosspiece varies in cross section the two ends and the middle portion being
bored of larger clear area than the intermediate parts (D). These intermediate
parts are bored of smaller clear area and may be bored a regular or irregular
polygon or round with keys or key beds, the object being to provide projections
to engage with other projections on the handlebar. A longitudinal slot is formed
running from end to end of the internal circumference of each of the intermediate
parts.
Each half handlebar (at its end farthest from the handle) is provided with a short
length (E) the outside shape of which corresponds with the intermediate parts (D)
of the crosspiece described in the preceding paragraph; it is also provided with a
small fixed key or stop (E¹) of such size as to pass through the slot above mentioned.
Next to the end piece of each half handlebar is a length of smaller cross
section (F) and next to this the usual bar.
A spiral or other spring (G) may be fitted in the bore of the crosspiece, this spring
to be in compression and tending to force both halves of the handlebar outwards.
Or two separate springs may be used, one for each half handlebar.
To attach either of the half handlebars the end is thrust into the bore of the
crosspiece until the end (polygonal or keyed) portion (E) has passed through into
the central bore or recess in the crosspiece, the small key or stop passing through
the slot provided for it. The handlebar is then revolved until it is brought
into the required position, and then drawn back until the polygonal or keyed end is
engaged in the corresponding part of the crosspiece, the small fixed key or stop
(now out of line with its slot) preventing the handle bar from drawing out, and
the spring or springs when inside the central bore of the crosspiece reducing lateral
vibration or slip.
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:-
A handlebar for cycles and the like which may be adjusted reversed or detached
without the use of tools, substantially as herein before described.
