COMPLETE SPECIFICATION.
Improvements in Bicycle Handle Bars.
I, GEORGE WARREN DREW, residing at 317, Elevenworth Street, San Francisco,
in the County of San Francisco, and State of California, United States of America,
Carpenter, 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 bicycle handle bars, and it has for its object to provide
a simple and improved mechanism which will enable convenient adjustment in a
vertical plane of the curved or horn type of handle bars.
The invention is fully disclosed in the following specification of which the
accompanying drawing forms a part, in which the separate parts of my improve-
ment are designated by the same letters of reference in each of the views, and in
which:-
Fig. 1 is a perspective view of a bicycle handle bar embodying my improve-
ments; and,
Fig. 2 is a detail sectional view, taken on a longitudinal plane.
In the drawing forming part of this specification A designates the standard or
head bar of the handle, which is provided at its top with a tubular cylindrical
stem, B, within the ends of which are respectfully received the corresponding
cylindrical ends of two projecting handle sections, C, which are curved or of horn
shape, as shown.
The ends of the handle section C are also tubular and interiorly carry catch
devices adapted to project into engagement with the shank B. These catch devices
preferably comprise flat spring plates, 1), interiorly secured at the end of the
handle section, as at d, and carrying at their free ends an outer projection pin or
stud, d, adapted to project through an eye or opening c, in the wall of the handle
section, at a point beyond the end of the carrying stem B, which pins or studs
serve as knob or finger pieces by which the catch device may be depressed and
operated.
The springs D also carry a supplementary pin or stud, d³, adapted to project
through an eye or opening c¹, in the wall of the handle section C, and engage a
registering eye or opening, b, in the wall of the carrying shank B.
The openings b are arranged in a series extending around the circumference of
the respective ends of the shank B.
The handle sections C are preferably respectively provided with two of the spring
catch devices D, arranged diametrically at opposite sides, for purposes of greater
strength.
It will be understood that when the handle sections are inserted within the
receiving ends of the tubular shank, they will be secured therein by engagement
of the pins or studs with the openings 6 in the shank.
To adjust the handle ends h, of the handle sections in a vertical plane, whereby
the handle is virtually raised or lowered to the desired degree of adjustment, it is
only necessary to depress the operating pins or studs d¹, to carry the inner pins

page_text: or studs d² from engagement with the openings b, when the handle section may
be turned within the carrying shank to the desired point of adjustment, and the
spring catch mechanism released so that it will then again engage other openings b
of the series of openings and retain the handle in its adjusted position and against
further turning movement.
It will be understood, that the handle sections C are thus adjustable in a rotary
manner within the carrying shank B, to raise or lower the handles as desired;
and, by reason of the improved, construction and arrangement as comprised in my
invention, the handle sections may be readily and conveniently separated from the
carrying stem, a collapsible handle being thus provided for the purpose of con-
tracting the required space in transportation or for any other reason.
To prevent permanent detachment of the removable handle sections from the
stem, and inconvenience from loss or theft, I prefer to connect said sections with
the stem by means of a flexible chain, E, or other suitable connecting device which
is permanently secured to both the handle section and the stem but which will at
the same time permit of the free operation of the mechanism in the manner above
described.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
-
..
1. An improved bicycle handle bar, comprising a head or stem, and handle
sections carried thereby and vertically adjustable with relation thereto, substan-
tially as set forth.
2. An improved bicycle handle bar, comprising a head or stem, handle sections
carried thereby and in movable connection therewith, and means for adjusting
the connection of said handle sections with the carrying stem to raise or lower the
handle, substantially as set forth.
-
3. An improved bicycle handle bar, comprising a head or stem; and handle
sections vertically adjustable with respect to said carrying stem and provided with
devices adapted to engage the latter at different points of adjustment, substantially
as and for the purpose set forth.
'
4. An improved bicycle handle bar, comprising a tubular cylindrical head or
stem, in combination with handle sections having corresponding ends fitted to said
stem and movable thereon in a rotary manner, and means for locking the handle
section and stem in connection at different points in the turning movement of the
handle section, substantially as and for the purpose set forth.
5. An improved bicycle handle bar, comprising a tubular cylindrical head or
stem, handle sections having a corresponding end received within the ends of
said tubular stem and adapted to turn therein; and devices for locking the enclosed
ends of the handle sections in connection with the tubular stem, substantially as
and for the purpose set forth.
6. An improved bicycle handle bar, comprising a tubular cylindrical head or
stem, and handle sections adapted to have their ends received by the ends of said
tubular stem and carrying spring catch devices adapted to engage the latter, sub-
stantially as and for the purpose set forth.
7. An improved bicycle handle bar, comprising a tubular cylindrical stem pro-
vided with eyes or openings arranged in a series extending around its circum-
ference, in combination with the handle sections having their ends corresponding
to and adapted to be received within the ends of the stem and provided with spring
catch devices adapted to engage said openings, substantially as and for the purpose
set forth.
8. An improved bicycle handle bar, comprising the tubular cylindrical head or
'stem having eyes or openings arranged in a series extending around its circum-
ference in combination with the handle sections having their ends corresponding

page_text: to and adapted to be received within the end of the stem and provided interiorly
with spring plates having outwardly projecting pins or studs adapted to engage
said openings in the stem, substantially as and for the purpose set forth.
9. An improved bicycle handle bar, comprising, in combination with a head or
stem, curved handle sections adjustably connected with said stem and adapted to
turn thereon, and means for securing said handle sections in their adjusted
position with relation to the stem, substantially as and for the purpose set forth.
10. An improved bicycle handle bar, comprising a head or stem, handle sections
detachably connected with and carried by said stem, and flexible chains or devices
extending between the handle section and stem and securing the detachable handle
section permanently to the stem, substantially as and for the purpose set forth.
