THOMAS SURTEES, Cleveland Place Norton, Stockton-on-Tees, Engine Fitter
JOSEPH UMPLEBY, 10 Paradise Row Stockton-on-Tees Engineer do hereby declare
the nature of this invention to be as follows:-
An apparatus to be fitted to cycles to counteract the vibration induced in
the framework of the cycles when in motion, and preventing shocks being felt by
the rider in the case of the cycle being ridden over rough or uneven ground.
The invention consists of the following parts, riz. :-A compensating concentric
spring with check action, a combined link and lever attachment, and coupling bolt
with spring adjustment. One pair of each part constituting one set.
The invention can be adapted to any existing cycle by removing the front wheel
from its original position and fitting to links of apparatus thereby bringing the
framework of the cycle into suspension and preventing all unequal motion of the
wheel being communicated to the rider. The adjustment can be graduated to suit
different weights, and the check action maintains the front wheel in position when
the cycle is lifted from the ground.
The features in this invention which are claimed by the inventor as new are-
The compensating concentric spring with central adjustment, and check
action.
The link and lever combination.
The compact form of the apparatus.
Its direct and simple action..
Its adaptability to the purposes of anti-vibration, and its application to such
purposes.

Improvements in Antivibrating Arrangements for Velocipedes.
THOMAS SURTEES, Engine Fitter Cleveland Place Norton, & JOSEPH
UMPLEBY, Engineer 10 Paradise Row, Stockton-on-Tees 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:-
This invention relates to improvements in antivibrating arrangements for
velocipedes and similar machines or vehicles, and the object of the said invention
is to suspend or support the framework of such velocipedes or similar machines by
means of springs, or a combination of springs, links or levers attached to the
framework and wheels of such machines or vehicles in such a manner as to render
them more durable, to counteract or eliminate vibration in the framework, and
prevent shocks being communicated to the riders when traversing rough or uneven
ground.
To carry this invention into practice an apparatus is constructed and fitted to the
velocipede in the form and manner as hereinafter described.
The apparatus consists of the following parts.
1st. A combined link and lever arrangement formed by forging, stamping,
casting or other mechanical means of metal or metals a flat circular boss or disc

page_text: with two arms or projections. radiating from the centre at right angles to each
other, one of the said arms or projections being in the form of a double curved
link, and the other arm or projection forming a lever, having a plane surface and
being in the same plane as the boss or disc, and having a cylindrical stud or pin
projecting from its plane surface at a suitable distance from the centre of the boss.
The aforesaid link and lever arrangement being constructed of one single piece of
metal, or the stud or pin projecting from the surface of the lever may be a
separate piece of metal and affixed to the lever by screws or rivets or other
suitable means.
2nd. A. compensating concentric metal spring of suitable size strength and shape
of cross section, the outer end of the said concentric spring having the form of a
loop, ring, fork or other suitable termination.
3rd. A metal coupling-bolt or cylindrical shaft or spindle the middle portion of
which is of larger diameter than the two ends and having a solid collar or flange
surrounding the middle portion and a loose collar or flange of similar diameter and
thickness to the solid collar fitted to one of the smaller ends of the shaft and bearing
against the end or shoulder of the middle portion. Both ends of the coupling-bolt
or shaft are screwed or threaded and fitted with suitable washers and nuts.
In order to complete the construction of the apparatus, the central disc of the
link and lever arrangement is fitted to the middle part of the coupling-bolt or
shaft, one side of the disc bearing against the solid collar and the loose collar or
flange bearing against the other side. The said link and lever arrangement when
so fitted to the shaft or spindle and secured between the aforesaid collars or flanges
possessing a free rotary motion governed by the concentric spring which is fitted
on the shaft or spindle at the other side of the solid collar or flange, and the loop
or fork or ring at its outer end is affixed by suitable means to the projecting stud
or pin on the lever.
The spring is secured in its proper position on the shaft by means of a washer
and nut fitted to the screwed end of the bolt.
When the various parts above described are fitted together and secured in their
proper positions the apparatus consists of a compact piece of mechanism having no
loose or separate parts, and, in order to carry out the purposes of this invention,
namely to suspend or support the framework of velocipedes, the apparatus is made
in duplicate and fitted to each side of the framework by means of the coupling-
bolts and nuts, the wheel of the velocipede being fitted to the double
curved links.
That this invention may be more readily understood and explained in detail,
hereunto is annexed a sheet of drawings on which letters of reference are marked
on corresponding parts of all figures alike.
DESCRIPTION OF DRAWINGS.
Fig. 1 is a side elevation of this invention shewing the concentric spring a
adjusted and secured on the coupling-bolt 6 and its outer end attached to the stud
or pin c on the lever d.
Fig. 2 is a plan view of this invention shewing the mode of suspending or
supporting the framework of a velocipede or other similar vehicle by means of the
combined link and lever and concentric spring fitted on both sides of the said
framework and wheel of the said velocipede. The hub of the wheel and a portion
Fig. 1 is a side elevation of this invention shewing the concentric spring a
adjusted and secured on the coupling-bolt 6 and its outer end attached to the stud
or pin c on the lever d.
Fig. 2 is a plan view of this invention shewing the mode of suspending or
supporting the framework of a velocipede or other similar vehicle by means of the
combined link and lever and concentric spring fitted on both sides of the said
framework and wheel of the said velocipede. The hub of the wheel and a portion
of the framework being shown in dotted lines, and do not form part of this inven-
tion. Part of this figure is drawn in section that the construction may be more
readily understood. e represents the central boss or disc of the link and lever
arrangement fitted to the middle part 6' of the coupling-bolt or spindle b between
the solid collar fand the loose collar J. The double curved links are shewn
attached to the hub of the wheel of the machine. The concentric spring a is shewn
fitted to spindle and secured against the solid collar by the washer i and nut.
The ends of the coupling-bolts 6 are attached to each side of the framework and

page_text: secured by nuts, and for the purpose of ensuring greater security, a key or feather
is fitted to the bolt and framework of the machine.
The above figures are drawn * full size.
From the above description of this invention it will be seen how the framework
of velocipedes and similar machines or vehicles may be suspended or supported and
vibration thereby minimised or eliminated when such machines are being ridden.
It will further be observed that when the machine is lifted from the ground the
wheel is retained in its position by the check-action of the concentric springs, the
coils of which closing upon themselves govern the action of the link attachment
and prevent the wheel from falling.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
1st. In the apparatus such as described for suspending or supporting the frame-
work of velocipedes or similar machines, the part of the apparatus herein described
as the link and lever arrangement, and its attachment to the framework of
velocipedes in the manner and for the purpose as herein substantially described.
2nd. In the apparatus such as described for suspending or supporting the
framework of velocipedes or similar machines the combination of a concentric
spring and coupling-bolt or shaft or spindle, and the attachment of such combi-
nation to the framework of velocipedes or similar machines, in the manner and for
the purpose as herein substantially described, set forth and fully illustrated in the
drawings hereunto annexed.
Dated this 7th day of January 1892.
