PROVISIONAL SPECIFICATION.
Improved Means for Mounting and Attaching the Handle-bars of
Bicycles.
I, THOMAS WIGSTON KINGLAKE CLARKE, of 9, St. Andrew's Square, Surbiton,
in the County of Surrey, Student, do hereby declare the nature of this invention
to be as follows:-
This invention relates to an improved mode of mounting, the handle-bars of
bicycles, with a view to enabling the handle-bar to be turi ed to a position in
which it coincides with the frame of the machine, stowing or packing for trans-
port being thereby rendered more convenient. The angular position of the
handles may, moreover, be adjusted to suit the fancy of the rider.
In applying my invention, by way of example, to what is known as a "drop"
handle-bar, the T-shaped socket through which the bar passes is furnished on
its, dependent part with a laterally projecting bearing in which works a stud
formed with an eccentric middle portion, that is to say, the stud is so formed
that when turned in one position it bears against the circumference of the "head
or steering bar, while when it is turned in the opposite direction the middle
portion is remote from the "head." The stud is furnished with a lever arm or
other handle for use in turning the same. The circumference of the head is
cut away at two, three or more points so as to form recesses for the stud to on-
gage in, thereby facilitating the setting of the handle-bar at right-angles to the
longitudinal centre-line of the machine.
For effecting the angular adjustment of the handle-bar, a series of holes are
made around a portion of the handle-bar; these holes running into, one another,
so that a slot with indented sides results. Upon or inside the handle-bar carrier
is mounted a stud or catch having a shank or stem formed with flattened sides,
or with flattened sides for a portion of its length, so that, when turned in one
position, it may be moved freely along the slot, while when it is turned at right-
angles, the wider portion of the shank or stem engages in one or another of the
widened portions of the slot and is thus maintained in the selected position.
The shank or stem may be screwed through the handle-bar carrier. Or 'the
catch may be pivotally mounted on the handle-bar carrier and may be formed
with a tail-piece which may be passed through the handle-bar carrier into the
slot in the handle-bar. A spiral or other spring may be applied to prevent. the
stud or catch shiftisg its position.

I, THOMAS WIGSTON KINGLAKE CLARKE, of 9, St. Andrew's Square, Surbiton,
in the County of Surrey,, Student, 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:
This invention relates to an improved mode of mounting the handle-bars of
bicycles, with a view to enabling the handle bar to be turned to a position in
which it coincides with the frame of the machine, stowing or packing for trans-
port being thereby rendered more convenient. The angular position" of the
handles may, moreover, be adjusted to suit the fancy of the rider.
In the accompanying drawings, Fig. 1 is an elevation of a portion of a handle-
bar mounted according to my improved method. Fig. 2 is a' corresponding
plan, a portion of the T-shaped socket being broken away: Fig. 3 is a vortical
section on the lino - in Fig. 1, Fig. 3 is a transverse section on the line y-y
in Fig. 3, and Fig. 4 is a horizontal section on the line -z in Fig. 1. Figs. 5
and 6 are views' illustrating my invention as applied by way of example to a
handle-bar of the "drop" type.
The T-shaped socket A through which the handle-bar B passes is furnished
on its pendent part with a laterally projecting bearing a in which works a stud c
formed with an eccentric middle portion c, the latter having a concave surface c
on one side. On the stud being turned to the position shown in the drawings
the 'eccentric portion bears against the circumference of the stem C of the head
or steering bar, while on turning it in the opposite direction, the middle portion
is' remote from the stem. The stud, c is furnished with a lever arm d or other
suitable means.for turning the same. The circumference, of the stem C is grooved
or cut away at two, three or more points c, c-so as to form recesses for the stud
to engage in, thereby facilitating the setting of the handle-bar at right-angles
to the longitudinal centre-line of the machine. To assist in retaining the stem C
in the socket A, the upper extremity of the stem is formed with a circumferential
groove wherein is placed a divided ring C, the latter being held stationary by
set-screws Cº.0°.
For effecting the angular adjustment of the. handle-bar, a circumferential
groove B is formed around the central portion of the handle-bar, holes bb being
drilled in the bottom of the groove for the reception of the reduced end of the
screw-stud or pin e; whilst the outer extremities of the holes are countersunk,
for the reception' of the conical portion of the said stud. Or a series of holes
may be made around a portion of the handle-bar; these holes running into one
another so that a slot with indented sides results, and wherein a stud or catch
engages this stud or catch being mounted upon or in the handle-bar carrier,
and having a shank or
stem formed with flattened sides, or with flattened sides
for a portion of its length so that, when turned in one position, it may be moved
freely along the slot, while when it is turned at right-angles, the wider portion
of the shank or stem engages in one or another of the widened portions of the
slot and thus maintains the handle-bar in the selected' position. Or the catch
may be pivotally mounted on the handle-bar carrier and be formed with a tail-
piece which may be passed through the handle-bar carrier into the slot in the
handle-bar. A spiral, or other spring may be applied to prevent the stud or
catch shifting, its position.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I claim :-
1. The improved method of mounting the handle-bar of a bicycle substantially
as herein described, whereby same is rendered capable of being set in alignment
with the frame, or its angular position adjusted to suit the fancy of the rider.
2. In mounting the handle-bar of a bicycle, the herein described means for
rendering same capable of being set in alignment with the frame, same com-
prising a stud having an eccentric portion arranged to enter recesses in the stem
of the handle-bar; the stud being carried in a bearing formed on the T-shaped
socket.
3. In mounting the handle-bar of a bicycle, the herein described means for
rendering the angular position thereof adjustable; same comprising a stud mounted
in the socket and arranged to engage in a circumferential groove formed in the
handle-bar.
4. The herein described means for rendering the angular position of a bicycle
handle-bar adjustable; arranged and operating substantially as described with
reference to Figs. 1, 2, 3, 5 and 6 of the accompanying drawings.
Dated this 16th day of September 1897.
