Improvements in and relating to Handle-bars for Velocipedes.
I, HUGH OSWALD BLAKER, of The Studios, Thurloe Square, Brompton, in the
County of Middlesex, Artist, do hereby declare the nature of this invention to
be as follows:-
This invention relates to handle bars for bicycles, tricycles and other veloci-
pedes, and it consists of means for rendering the position of the handles or grips
adjustable, the object being to enable the rider to raise or lower the handles or
grips at pleasure while riding, without either varying the slope of them or
depriving the rider-during the operation of altering their position-of means
for steering and controlling the machines.
According to my invention, I form the handle bar of three parts. The one, a
straight central part carried by the pillar in the ordinary manner, and the other
two the end parts-carrying the handles or grips which said parts are curved or
otherwise suitably shaped. These end parts are pivotted to the central part by
suitably arranged hinges whereby each end of the handle is allowed a radial
movement around its point of pivot in the vertical or approximately vertical
plane.
To enable each end of the handle bar to be fixed at any desired position each is
provided with a locking device of which the following is a convenient construc-
tion: In or along the bar is mounted a sliding rod having teeth or serrations
formed en its end adapted to engage with the teeth or serrations
of a quadrant carried by the end of the central part of the bar, the said locking
rod being provided with a suitably arranged spring adapted to keep the teeth
or serrations in gear with the said quadrant. This sliding rod is provided with
a trigger or thumb piece which passes out through a slot-preferably on the
underside of the handle bar-so that the said locking rod may be drawn back when
it is desired to alter the position of the adjustable part of the bar.
I sometimes use a locking trigger for locking the operative part of the locking
device so as to prevent it being accidentally actuated."
It will be seen that by this construction the raising or lowering of the handles
or grips does not vary the slope of them, and further it permits one handle or
grip to be raised and lowered independently of the other or to a greater or less
degree.

I, HUGH OSWALD BLAKER, of The Studios, Thurloe Square, Brompton, in the
County of Middlesex, Artist 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 handle bars for bicycles, tricycles and other veloci-
pedes, and it consists of means for rendering the position of the handles or grips
adjustable, the objects being to enable the rider to raise or lower the handles or
grips at pleasure while riding, without either varying the slope of them or
depriving the rider-during the operation of altering their position-of means
for steering and controlling the machines, to provide a reliable locking device so
that the parts of the bar form one rigid whole when locked together, and to
simplify construction and enable repairs to be readily effected.
In the accompanying drawing which illustrates my invention:-
Figure 1 is a broken view in elevation-partly in section.
Figure 2 is a broken view in plan also partly in section and Figure 3 is a
view in transverse section on line y, y, Figure 1.
Throughout the views similar parts are marked with like letters of reference.
The handle bar pillar A carries at its upper end the usual T piece a, in each
end of the horizontal part of which is fixed-by brazing or otherwise-a piece B
forming the male part of a hinge joint with which a piece C, forming the female
part thereof, engages, and is secured by a transverse pin D formed in two parts
as shown for convenience and neatness. The piece carries a sliding piece or
finger having serrations adapted to engage with similar serrations on the
piece B. The locking piece or finger is hollow and contains a spiral spring
acting between it and a cape closing the outer end of the chamber in the piece C
containing the finger E. To the finger E is fixed a rod E which passes through
the cap and is connected by a link G or its equivalent with a lever I pivotted
to the tubular part X of the handle bar at or near the handle or grip Z mounted
thereon. This lever H projects through a slot in the tubular part of the bar
and is suitably shaped to enable it to be gripped by the fingers. By operating
this lever the locking piece or finger E can be withdrawn from engagement
with the serrations on the piece B thus allowing the one half of the handle bar to
to be raised or lowered as desired, the spring F returning the locking finger E
into engagement with the piece B when the finger lever H is released.
The serrations of the finger E and the piece B are so arranged that the parts
of the handle bar can only be locked in three positions with respect to the pillar A,
and to relieve the serrations of some of the strain thrown on them when the
parts of the bar are in their highest and lowest positions, a transverse pin J
is mounted in the jaw of the piece C which passes through a slot b in the piece B
and engages its ends when the said parts of the bar are at their highest and
lowest positions respectively.
It will be understood that both end pieces of the handle bar are mounted and
pivotted as herein described and that the position of each can be varied indepen-
dently of the other, consequently it is quite easy to alter the positions of the
handles or grips whilst riding by operating one part of the bar at a time which
ensures one half of the bar being always available for steering and balancing
purposes.
The tubular parts X of the bar are fixed to the pieces C by means of coupling
nuts thus providing a ready means of connecting up the parts and of getting at the

page_text: locking devices for the purpose of adjustment or repairs. On the inner end of
each tubular part X is formed an enlargement with which a sleeve nut K
engages the said nut being adapted to screw on to the exterior of the piece which
is threaded to receive it, and so pull up the part X into engagement with the
piece C, the abutting faces being arranged to interlock by means of projections c¹
on the piece C and corresponding recesses in the enlargement of the bar X
to take the twisting strain of the curved parts of the bar.
I am aware that it is not broadly new to make the handle bars of cycles adjustable
for the purpose of varying the positions of the handles or grips, and I do not
therefore claini such broadly, but having now particularly described and ascer-
tained the nature of my said invention and in what manner the same is to be
performed, I declare that what I claim is;-
(1) The combination in a cycle handle bar, of a centre piece having at each end
the male part of a transverse hinge or joint, of pieces forming the female parts of
the hinges or joints hinged to the male parts by transverse pins, of locking
fingers contained in the parts forming the female parts of the hinges or joints and
having serrations adapted to engage similar serrations on the male parts of the
hinges or joints, of curved tubular end pieces attached to the pieces forming
the female parts of the hinges or joints by means of coupling or connecting nuts
and carrying handles or grips at their outer ends, of levers pivotted to the curved
tubular parts of the handle bar and connected with the locking fingers by rods or
links so that they may be withdrawn out of engagement with the pieces forming
the male parts of the hinges or joints, of springs mounted in the hollow locking
fingers and adapted to return them into contact with the pieces forming the male
parts of the hinges or joints, and of transverse pins carried by the piece forming
the female parts of the hinges or joints and adapted to engage the ends of slots
formed in the pieces forming the male parts of the hinges or joints, as set forth.
(2) The improved adjustable handle bar for cycles substantially as herein
described and illustrated by the accompanying drawing.
