PROVISIONAL SPECIFICATION.
Improved Adjustable Handle Bar to Bicycles, and the like
Machines.
We THOMAS ALLEN MARSHALL and CHARLES DUDLEY MARSHALL,
Campbell Works, Stoke Newington, London, N. Dandy Roll Makers, do hereby
declare the nature of this invention to be as follows:-
The arrangement for steering, steadiness, and otherwise support of the body in
bicycle riding is by means of a handle attached to each end of the handle or steering
bar, which in many instances places the rider in inconvenient position, also has
tendency to uncentralise the weight of the body on the machine, to obviate which
he grasps the bar right and left of the head. The bar being of metal, and small
in circumference, the rider is very liable to cramp or contraction of the muscles
of the hands, rendering him unable to have physical power or thorough control over
the machine, hence accidents (too often serious) occur.
By this invention we fit on the handle bar, on each side, and in close proximity
to the head, one or more handles, made of cork, or other adaptable material of
warmth retaining nature to mitigate the severe chill to which the hands are subjected
in cold weather, the handles are of such dimensions as to give the rider a firm grasp,
thus a greater command over the locomotion of the machine, he is able to ride in a
convenient, also safer position his weight on the machine being centrally balanced,
and the handles being of suitable proportions the tendency to cramp or muscular
failure in the hands is prevented.

Improved Adjustable Handle Bar to Bicycles, and the like
Machines.
We, THOMAS ALLEN MARSHALL, and CHARLES DUDLEY MARSHALL, of
Campbell Works, Stoke Newington, in the County of Middlesex, Dandy Roll
Makers, 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 :--
Our invention relates to the handle-bars of velocipedes and the like, and comprises
the improvements hereinafter set forth.
It is a common practice with cycle riders to occasionally grasp the handle-bar
with each hand at some point near the centre. This practice is rendered
objectionable in the case of the ordinary handle-bar owing to the said bar being of
comparatively small diameter, and thereby not affording a sufficient surface to
ensure a firm grasp being taken thereof; and also when the said bar is of metal,
as is usually the case, by reason of its chilling the hands of the rider during cold
weather.

page_text: To obviate these objections, and enable the rider to grasp the handle-bar, when
desired, at points nearer the centre, or closer together than those afforded by the
ordinary handles or grips, we provide upon the handle-bar two additional or
supplementary adjustable or other handles or grips.
In the accompanying drawing we have shown how our said invention may be
conveniently and advantageously carried into practice.
Figure 1 is a front view of a handle-bar fitted with our additional or supple-
mentary handles or grips.
Figure 2 is a similar view to Figure 1, showing a slight modification of our said
invention hereinafter described.
Like letters indicate corresponding parts throughout the drawing.
A is a portion of the handle-bar stem, B is the handle-bar and C, C are the
ordinary or usual handles or grips.
According to our said invention we provide additional or supplementary handles
or grips D so mounted as to enable the rider to grasp the same when desired in lieu
of the ordinary handles or grips C. To enable the additional or supplementary
handles or grips D which may be formed of cork, felt, or other suitable material,
to be secured in position, and also to render them adjustable lengthwise upon the
bandle-bar, we preferably construct each of the said additional or supplementary
handles or grips D in two halves or portions, and secure the said halves or portions
together, when in position upon the said handle-bar, by means of clamps D* and
screws or bolts D₁ as shown.
In some cases, however, we may provide screw-collars or ferrules adapted to
screw upon the extremities of the said additional or supplementary handles or grips,
which latter are then slightly tapered so as to cause them to be firmly clamped or
fixed in position upon the handle-bar when the said screw-collars are in position.
Instead of forming each of the said additional or supplementary handles or grips
in two parts or halves as above mentioned, we may form one split lengthwise in
each of them, which, when they are made of suitably elastic or flexible material,
will admit of their being sprung over the handle-bar and thus placed or got in
position thereon.
In the modification shown in Figure 2 instead of securing the additional or
supplementary handles or grips D upon the main handle-bar B as above described,
we place them upon a second short handle-bar E which may be situated slightly
above, and in line with, the said main handle-bar B, and secured thereto by a short
stem or neck as shown.
Although we have herein before described suitable methods of attaching the
additional or supplementary handles or grips D to the handle-bar we do not limit
ourselves thereto as obviously the same may be attached in any other convenient
manner.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. A handle-bar for use on velocipedes or the like provided with additional or
supplementary handles or grips either fixed, or adjustable lengthwise upon the said
handle-bar, substantially as and for the purpose specified.
2. The improved handle-bar for use on velocipedes or the like constructed
substantially as described with reference to either Figure 1 or to Figure 2 of the
accompanying drawing.
Dated this 5th day of March 1897.
