PROVISIONAL SPECIFICATION.
Improvements in Velocipedes and such like Machines.
I THOMAS LEIGH MITCHELMORE of 31 Derby Road, Nichols Town, Southampton,
in the county of Hampshire, Engineer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to an improved handle-bar for velocipedes and such like
machines, constructed as hereinafter described. The object of this invention is to
allay excessive vibration of the handle-bar where the same is grasped by the rider,
with this object in view I make the tee-piece through which the handle-bar passes, in
two pieces, afterwards connected together by bolts and nuts, this tee-piece is of hollow
construction, inside this hollow tee piece I provide another tee-piece which is connected
to the handlebar but works freely within the hollow tee piece. When riding the
machine the vibration of the handlebar is communicated to the inside tee-piece, the
lower part of which acts upon an india-rubber or other spring provided within
the hollow tee-piece at its lower part, the vibration of the handlebar is taken by this
spring and regulated thereby.
The necessary free rotary action of the handlebar is secured by a ball bearing
arrangement within the hollow tee piece which renders it impossible for the handle
bar to become fixed where it passes through same also by means of the ball bearing
arrangement as applied to the handlebar, there can be no possible movement of the
handlebar in a transverse direction.
It is noted that by means of my invention the action of the handlebar is similar and
uniform at each end of same where grasped by the rider, and also while it is possible
to depress the handlebar at each end, at the same time it is impossible for it to lift at
its ends beyond a certain fixed and convenient height.
My invention is also applicable to seat pillars, and foot rests, and can be applied to
any existing type of velocipede, or such like machines.
The parts of the machine comprised in my invention may be made of iron, steel,
brass, or other suitable metal or alloy.

COMPLETE SPECIFICATION.
Improvements in Velocipedes and such like Machines.
I THOMAS LEIGH MITCHELMORE of 31 Derby Road, Nichols Town, Southampton,
in the county of Hampshire, 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 :-
This invention relates to an improved handlebar for velocipedes and such like
machines constructed as hereinafter described. The object of this invention is to allay
excessive vibration of the handlebar where the same is grasped by the rider, with this
object in view I make the tee piece through which the handlebar passes in two pieces
afterwards connected together by bolts and nuts this tee piece is of hollow construction,
inside this hollow tee piece I provide another tee piece which is connected to the
handlebar but works freely within the hollow tee piece.
When riding the machine the vibration of the handlebar is communicated to the
inside tee piece the lower part of which acts upon an india-rubber or other spring
provided within the hollow tee piece at its lower part the vibration of the handlebar is
taken by this spring and regulated thereby.

page_text: The necessary free rotary action of the handlebar is secured by a ball bearing
arrangement within the hollow tee piece which renders it impossible for the bandle
bar to become fixed where it passes through same, also by means of the ball bearing
arrangement as applied to the handle bar there can be no possible movement of the
handlebar in a transverse direction.
It is noted that by means of my invention the action of the handlebar is similar and
uniform at each end of same where grasped by the rider and also while it is possible
to depress the handlebar at each end, at the same time it is impossible for it to lift at
its ends beyond a certain fixed and convenient height.
My invention is also applicable to seat pillars and can be applied to any existing
type of velocipede or such like machines.
The parts of the machine comprised in my invention may be made of iron, steel,
brass, or other suitable metal, or alloy.
In order to enable my invention to be fully understood I will proceed to describe
the same with reference to the accompanying drawings in which Fig. 1. is a sectional
elevation Fig. 2. a plan on top of Fig. 1. Fig. 3. a sectional elevation at right angles
to Fig. 1. Fig. 4. a plan of Fig. 3. with top part reinoved. Fig. 5. a section through
the lines A. A. in Figs. 3. and 4. Fig. 6. a reduced plan of steering or handle-bar
and Fig. 7. a side elevation of Fig. 6. the handlebar E. as shewn in full lines at Figs. 6
and 7. represents the same when at rest and the handlebar in dotted lines as shewn
at E in Figs. 6 and 7. represents approximately the greatest distance the same can
drop the handlebar being free, subject to the control of the spring G. to move up and
down between the two positions as indicated at E. and E' in Figs. 6 and 7. Figs. 1.
2. 3. 4. and 5. shew in detail the hollow tee piece which forms in my invention the
part of a velocipede or such like machine through which the handle bar passes and
this hollow tee piece is connected to the steering tube or bar B by such means as is
shewn in sectional elevation and plan at C. C. or by other approved method.
I further provide and fit inside this hollow tee piece another tee piece as shewn in
section, elevation and plan at D. D. D. and through the centre of which the handle
bar passes and to which it is connected this fitting D. is free to revolve in a portion
of a circle within the hollow tee piece, consequently the handlebar E. is equally free
to revolve with the fitting D. as it is through this fitting D. the handlebar passes and
to which it is connected.
To further secure the free rotary action of the fitting D. and consequently the
handlebar E. I provide that the fitting D. shall revolve on ball bearings F. as shewn
at Figs. 3. 4 and 5. and to regulate the rotary action of the handlebar acting through
and upon the fitting D. I provide within the hollow tee piece a spring G. the vibration
of the handlebar is communicated to the tee piece D. and from thence to the spring G.
and absorbed by same. The spring G. can be adjusted by the screw H. at will.
In the application of my invention to seat pillars the following is the arrangement.
To the top of the seat pillar a hollow tee piece is fitted exactly similar in construction
in every respect, to that through which the handle har passes see Figs. 1, to 7, a short piece
of rod or tube passes through this tee piece of sufficient length to allow of a connection
being made between the bottom part of the framework of the seat and this piece of
tube or rod, in other words, the seat is hung and hinges upon this piece of tube or rod
passing through the hollow tee piece the result being that any vibration of the seat is
communicated to the tee piece or fitting D working within the hollow tee piece and
is regulated and absorbed by the spring G. in exactly the same way as is the vibration
of the handlebar E as hereinbefore substantially 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. The particular hollow shape and construction of the tee piece which forms the
top part of the steering tube or bar through which the handlebar passes and the top
part of the seat pillar to which the seat is connected as substantially described.
2. The particular form construction and rotary action of the tee piece working

page_text: within the hollow tee piece and especially the application of the ball bearing arrange-
ment to same as substantially described.
3. The particular application of a spring fitting working within the hollow tee piece
by means of which the vibration of the handlebar and seat is regulated and absorbed,
as substantially described.
