page_text: I, BRUCE GREEN, of 374, Camden Road, London, N.W., Gentleman, do hereby
declare the nature of this invention to be as follows:-
The object of this invention is to prevent or lessen the passage of vibration to
by or through the handle bars of cycles.
For this purpose I adapt the handle bars to rotate in a socket or sockets on
the stem by which it is fixed in the steering head of the cycle, preferably bifur-
cating the said stem at or near its upper end to provide two alligned sockets for
the handle bar, and I provide the handle bar near said socket or between said
sockets with a projecting arm or preferably with two such arms projecting in
opposite directions. Such arm or arms are caused to bear against a spring or
springs or a cushion or cushions for instance pneumatic cushions which have
counter bearing or support against the stem of the handle bar or against a pro-
jecting arm or against two projecting arms respectively on the stem or attached
thereto or similarly made to afford a rigid support or supports for the spring or
springs or cushion or cushions.
It will be understood that I do not confine myself to having one arm only
projecting in each of two opposite directions that is to say having opposite
bearing one to the other but may duplicate or multiply the number of such arms
and spring or cushion bearings.
The sockets in which the handle bar rotates can have interior rubber sleeves or
hollow pneumatic sleeves for more effectually preventing or lessening the passage of
vibrations or may employ ball bearings in the said sockets.
Where one arm is used with its counter arm or counter bearing the spring
may be connected to the same so as to act both in tension or compression. I may
also employ spring arms having their ends connected or curved or returned springs
to operate in the same member.

I, BRUCE GREEN, of 374, Camden Road, London, N.W., Gentleman do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:
The object of this invention is to prevent or lessen the passage of vibration to
by or through the handle bar of cycles.
For this purpose I adapt the handle bar to rotate in a socket or sockets on
the stem by which it is fixed in the steering head of the cycle, preferably bifur-
cating the said stem at or near its upper end to provide two alligned sockets for

page_text: the handle bar, and I provide the handle bar near said socket or between said
sockets with a projecting arm or with two such arms projecting in
opposite directions. Such arm or arms are caused to bear against a spring or
springs or a cushion or cushions for instance pneumatic cushions which have
counter bearing or support against the stem of the handle bar or against a pro-
jecting arm or against two projecting arms respectively on the stem or attached
thereto or similarly made to afford a rigid support or supports for the spring or
springs or cushion or cushions.
It will be understood that I do not confine myself to having one arm only
projecting in each of two opposite directions that is to say having opposite
bearing one to the other but may duplicate or multiply the number of such arms
and spring or cushion bearings.
The sockets in which the handle bar rotates can have interior rubber sleeves or
hollow pneumatic sleeves for more effectually preventing or lessening the passage of
vibrations, or I may employ ball bearings in the said sockets.
Where one arm is used with its counter arm or counter bearing the spring
may be connected to the same so as to act both in tension or compression. I may
also employ spring arms having their ends connected or curved or returned springs
to operate in the same member.
The annexed drawing illustrates a form of construction in which the handle
bar has one rearwardly extending arm having bearing on a spring which has
counter bearing on another arm projecting rearwardly from the stem of the
handle bar. Fig. 1 is a rearward elevation, Fig. 2 is a sectional side elevation
and Fig. 3 a plan illustrating this form of handle bar.
A represents part of the front of a cycle frame B is the stem carrying the
handle bar C. This stem B is forked at D and at the ends of the fork I are
two alligned bearings E preferably ball bearings of any suitable construction
supporting the handle bar C so that the latter may turn in said bearings. F is
an arm on the handle bar and G a counter arm on the stem B. H is a coiled
spring attached at its ends to arms F and G respectively.
It is obvious that pressure downwards upon the handles J results in a com-
pression of the spring H which thus cushions such downward pressure. Upward
pull on the handles J also results in an extension of the spring H, but to prevent
excessive upward pull and to provide a limit for the same any suitable stop
may be conveniently employed as for instance a pin K on the handle bar a
which on extreme upward pull of the handles J comes in contact with a lug L on
the side of the bearing E.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. The combination with a stem such as B having a bifurcated end D, of a
handle bar curved rearwardly and mounted to revolve on a horizontal axis in
said bifurcated end, the handle bar having an extended arm such as F or extended
arms having bearing on springs or cushions having counter bearing on an arm
or arms extending from the stem aforesaid and forming means for cushioning
the rotation of the handle bar in its stem substantially as described.
2. A handle bar with its stem and cushioning device constructed substantially
as herein set forth.
