Improvements in or appertaining to Bicycles.
A communication by WILLIAM H. BROWN, of 678 Euclid Avenue, Cleveland, in
the State of Ohio, United States of America, Manufacturer.
1, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool and 6 Bank Street,
Manchester both in the County of Lancaster, 118 New Street, Birmingham
in the County of Warwick and 322 High Holborn in the County of Middlesex,
Civil Engineer, 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 object of this invention is to provide a handle bar of novel construction,.
in which the extremities to which the grips are secured may be quickly and easily
adjusted as to height, and as to their distance from the axis of the steering head.
The invention consists of a handle bar constructed substantially as shown in the
drawing and hereinafter described.
The accompanying drawings show this invention in what is now considered the
most desirable form, but in certain details, particularly the means for clamping
the two handle bar sections to the head post, the construction may be varied
without departing from the spirit of the invention.
In the drawing

bicycle;

bar sections and the head post;
Figure 5 is a detail view of the clamping screw and spring washer; and
Figure 6 is a sectional view through the joint by which said parts are united.
D represents the head post of the handle bar, which is adapted to be secured in
the steering head of a bicycle in the usual manner. At the top of this post a
flattened disk shaped head d is formed. Upon the inner ends of the two handle
A hollow stud
bar sections A and B, are respectively formed the disks a and b.
bolt is formed in the middle of the disk d, projecting at right angles therefrom.
Both of the disk shaped ends a and b are perforated, and are pivoted upon said
stud bolt. This stud is internally threaded, and it receives the clamping screw C..
having a sufficiently large head c for the purpose. Between the head c and the
outer face of the rear disk b, a spring washer E is placed.
In order that the members of the handle bars may be securely fastened in any
desired relative position, the engaging faces of the three disk shaped ends a, b.
and d are notched or serrated radially as shown. The serrations interlock, whereby
a comparatively slight pressure from the clamping screw will hold the members
positively against accidental displacement.
By means of the described construction, the height of the extremities or grips.
may be adjusted to any position within a wide range, as indicated in the drawing;
and these changes may be made very quickly by a skilful rider, without dismounting
from his. bicycle.
The members A and B may be transposed from one side to the other, and
thereby the form of the bar will be very materially changed. The members of
the bar may be folded down close to the frame of the bicycle, thereby greatly
economizing room when the bicycle is stored or packed.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is :-
1. In a handle bar, the combination of the post, having a disk shaped head, the
two handle bar sections having corresponding disks at their inner ends,-which
three disks are pivoted together on a common axis, the contacting surfaces of all
the disks being provided with interlocking serrations, and a clamping device to
clamp the three disks together, substantially as set forth.
2. In a handle bar, the combination of the post, having a head composed of a
single flattened disk, and projecting stud integral therewith, the two handle bar
sections having corresponding disks on their inner ends which are pivotally
mounted on the stud bolt, a clamping screw in the stud bolt, the contacting surfaces
of all the disks being provided with interlocking serrations, substantially as set
'forth.
3. In a handle bar, the combination of the post with its flattened head and
projecting stud bolt made integral therewith, the two handle bar sections which
are pivotally mounted on the stud bolt, and a spring washer lying between the
head of the clamping screw and the face of the adjacent surface of the handle bar
section, substantially as set forth.
Dated this 4th day of August 1896.
