A Detachable Anti-vibration Device for the Handle or Steering Bar
of a Velocipede, Autocar or other Vehicle or Machine.
I, GEORGE CHAPPELL, 5, Great Stanhope Street, Mayfair, London, W.,
Mechanical Engineer, do hereby declare the nature of this invention to be as
follows:-
A simple device which may be fitted to or within the head or handle bar of
a velocipede, autocar, or other vehicle or machine or in any part where vibration
is to be reduced or overcome, such device to cushion the handle bar or equivalent
part both upwardly and downwardly.
The handle bars of triple cycle heads having two stems, and there being two
barrels to receive them in which they slide telescopically, & allow them to play
freely and place coiled springs beneath the plugged ends of the handle bar
stems to cushion the downward thrust.
A rod and tube is attached to the handle bar, a foot on the tube carries a
coiled spring which is placed inside the centre stem and rests against the top
crown to cushion the upward pull. Or both upward and downward spring resis-
tance may be obtained in the centre stem-the outer stems forming guides.
A rod may run through the barrels to hold the springs in position or support
discs.
In the case of single heads the barrels are not continued to the fork crown,
but are plugged at their ends or attached to a base plate.
By releasing a screw or otherwise the handle bar may be detached or adjusted.
Rubber or other buffers, or air chambers may be used, in connection with or
instead of, either, or any, of the springs.

page_text: to or within the head or handlebar of a cycle or other vehicle or machine, or in
any part where vibration is to be reduced or overcome, such device to cushion
the handlebar or equivalent part both upwardly and downwardly, or in both
directions in the line of its extension.

The annexed drawings represent a front view partly in section shewing the
improvements. The outer tubes or barrels A are brazed to the crown B, the
handlebar C is provided with two stems P closed at their ends by plugs E.
spring F is placed loosely in the-barrels on which the closed ends of the stems
rest to cushion the downward thrust. A rod and tube G with a foot or washer H
carries a spring I, bearing against an upper crown or guide plate J, to cushion
the upward pull, or rebound. The central holder G, consists of a rod and tube,
capable of extension, and held in position by the clip M, after the manner of an
ordinary brake rod, so that by releasing the nut M, the required adjustment may
be obtained, or the handlebar detached. For single heads the barrels A, need
not be attached to the crown B, but may be plugged at their lower ends, or
attached to a base plate, the whole being carried by the guide plate J.
my
Having now particularly described, and ascertained the nature of
invention and in what manner the same is to be performed I declare that what
said
I claim is
1. In a cycle, or the like, an antivibration device, in which spring action is
obtained in both directions, in telescopically sliding tubes, consisting in a piston P
sliding in a tube or chamber A, and bearing on a spring F, a rod or central
holder G, having a foot or washer H, and carrying a spring I, to bear against
the closed end of the central stem K.
2. The above construction in the handlebar, or triple, or other head, of a
cycle, or other vehicle, substantially as above described, and shewn in the
drawings.
