Improvements in and relating to Anti-vibration Arrangements for
Cycles of all kinds.
I, WILLIAM DEAKIN, of 212, Soho Road, Handsworth, near Birmingham, Builder,
do hereby declare the nature of this invention to be as follows:-
This invention in connection with cycles relates to certain improved arrangements
in the method of construction whereby vibration when riding is greatly reduced or
prevented and at the same time resiliency is obtained.
The method consists of a kind of telescopic action brought about by the metal
tubing comprising the front fork and certain parts of the frame working in connection
with suitable coiled or other springs or plugs or cushions of india rubber, so that the
bearing or thrust is taken up by the elasticity of the springs or rubber as hereafter
more particularly described:
For my purpose I construct the sides of. the front fork of the wheel so that they
are not rigidly connected with or integrally a part of the upper portion or handle
pillar. The two sides of the fork are provided with a crown plate at their upper part

sides I insert about mid-way (more or less) a suitable coiled or other spring which
obtains a seating, and bears upon a solid washer brazed or otherwise attached within
each inner tube, said inner tubes are brazed into two bottom crowns or plates. The
said springs are retained in place by suitable screw nuts which are screwed into
the top of each fork side and pass through the crown plate and also keeps same
rigid.

purpose I form the upper part of this member of the frame with a collar or
extension or bridge from or connecting the ☐ sides which carries a tubular
portion.
In connection with the top lug of frame surrounding the support I loosely attach
a tubular portion which slides telescopically outside the above named tubular portion
and within said tubes is a coiled or other suitable spring.
The action of the above described arrangements is thus, the rider's weight upon the
frame obviously depresses the springs in the front fork tubes as also the back stay
spring so that the frame is capable of rising and falling a certain distance. The
tubular connections of the back stay with the spring also become compressed by the
rider's weight consequently the entire bearing and thrust is received and taken up
by the said spring connections and whereby it will be understood that the whole
frame is governed by the said springs or elastic bearings thus affording resiliency..

and if required said springs may be surrounded by rubber or other suitable sleeves

As previously stated I may sometimes substitute rubber plugs in lieu of coiled or
other springs so as to provide elastic and resilient bearings the other arrangements
will be the same, but preferably springs will be employed.

Improvements in and relating to Anti-vibration Arrangements for
Cycles of all kinds..
I, WILLIAM DEAKIN, of 212, Sobo Road, Handsworth, formerly, but now of
Montague House, Charles Road, Small Heath, near Birmingham; Builder, 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 refer-
ence being had to the accompanying sheets of drawings and to the figures and letters
shewn thereon.
My present invention in connection with cycles relates to certain improved arrange
ients in the method of construction whereby vibration when riding is greatly
reduced or prevented and at the same time increased resiliency is obtained.
.
To attain this end I employ a kind of telescopic action in connection with the
upper and lower parts of the machine, brought about by the metal tubing of the
front fork and the rear diagonal member of the frame being adapted to operate in
conjunction with suitable coiled or other springs or plugs or cushions of india-rubber,
but preferably coiled springs so that the bearing or thrust is taken up by the elasticity
of the springs or rubber as hereinafter more particularly described.
With reference. to the drawings :-

For my purpose I construct the sides of the front fork of the wheel so that they
are not rigidly connected with or integrally a part of the upper portion in connection
with the handle pillar or tube. Iforin the said fork as it were in two parts, an
upper and lower, and I extend the fork sides much higher than the usual
kind.
:
The two sides of the fork A have tubular extensions A¹ and a centre tube A2 fitting
on to and over these tubes A1, A2 is the upper tubular part of the fork B¹, B², consisting
of cylindrical chambers B¹ which receive the side tubes A¹ in about mid-way of their
depth. Within the upper part of the tubes B¹ coiled springs C are placed (or other
springs or plugs of rubber) the base of these springs obtain a seating upon the
tops of the tubes A¹ of the fork or upon suitable washers if required' inserted
between same:
Midway of the fork, suitable crown plates D, D₁ are provided. The upper tubular
part is also provided with a crown plate D2 and lock nuts
E, E,
E².
The handle rod F is received by the tubular pillar A2 which is in turn enclosed
within a tube As that is brazed to the crown plate D³ which is received by the ball
head pillar 'B².
Ball bearings in ball races are located at the top and bottom junction lugs g g¹
of the frame with the pillar B².
The said coiled springs C are retained in place in their cylindrical chambers by
suitable screws G which are brazed in to the top ends of the tubes or cylindrical
'chambers B₁ and over which the crown' plate D2 fits screw nuts G¹ firmly securing
same in place.
The tube B2 of the upper part of the fork is supported with the two sides B¹ upon
'the crown' plate' D3 by being brazed or otherwise attached thereto. The top of the
tube B² is surmounted by a cone piece H fitting over the ball bearings of the lock
nut E2 secures the said cone in place, a second lock nut E' fits above E² and the
crown plate D2 is adjusted at this part by a third lock nut E upon the top of the
crown plate.
Referring to the telescopic arrangement of spring or elastic bearing in connection
with the rear part of the machine."
In this case I utilize the diagonal back fork stay as the receptacle for the spring.
In the first place I construct the back" stay above the fork in two tubular
parts J, J, the part J accurately. telescoping within the tubular part J¹.
At the top of the tube J is a collar extension or bridge K which is jointed at K¹
by means of ear pieces on to the top lug L of the frame, a shouldered screw pin and
nut or other device securing same.
1:4
This joint pin is specially adapted for the purpose intended and consists of a
shouldered head" K Figure 15, the other end of the pin has a loose shouldered
collar K³ fitting over, and a screwed end and screw nut K, the ear pieces of the
collar K are received by and work upon the shoulders of the head K² and collaŕ K³
the spindle passing through the lug Land so making the joint.
Within the tubular parts J; J is a coiled spring M by preference (or other suitable
springs or spring substance can be used) this spring in its normal condition and
when there is no pressure upon same is of the same length relative to the tubular
parts J, J. Passing up within this spring M is a spindle formed of two tubes N, N1
which are free to slide up and down, the one within the other, a slot O is provided in
the tube' N and a stud' 0'' is upon the tube or rod" N₁ which slides within the said
slot and acts as a stop. This tubular telescopic spindle with the spring around it,
is' secured in the outer tubes J; J by means of screwed ends and screwed' nuts P,
said screwed ends passing through apertures in the collar K and" crown' piece or
bridgë K³.
The object in having a telescopic spindle" will be" obvious, and the slot" O and

page_text: stud 0 is to prevent the outer tubes J J¹ from pulling out or apart, the tubular
spindle allowing of a free up and down action though held tightly at K and K5.
Referring to Figures 12 and 13 and to the part shewn on Figure 1.
It will be seen that the horizontal stays Q are jointed at Q' to the tubes in
connection with the bottom bracket R, thus making a false bridge, a suitable 5
kind of joint is such as illustrated consisting of a screw pin h and nuts h¹ which
secures the two ☐ sides of the horizontal stay in the joint piece h².
The object in having this joint is to allow of freedom of action when the frame. is
depressed by the rider's weight and to relieve the frame from undue strain.
Further, as an alternative the ends of the horizontal stays near to the rear wheel 1
may be jointed instead of rigid with the rear wheel axle, if circumstances render it
expedient to so locate the joint instead of at the front part.
The action of the above described arrangements is thus-The rider's weight
upon the frame obviously depresses the springs in the front fork tubes B¹. The
top member S of the frame and the front diagonal member S¹ being connected
by their lugs to the tubular part B2 which is, part of and permanent with the side
cylindrical tubes B₁ and rises and falls by the action of the springs, C upon the
supporting tubes A¹. The tubular connections J, J₁ of the back stay and the
telescopic spindle N, N' and spring M are also depressed. Thus the cycle frame
is capable of a slightly upward and downward movement, consequently the entire
bearing and thrust occasioned by the weight of the rider is received and taken up by
the spring connections and telescopic action referred to, and whereby it will be
readily understood that the entire frame is governed by the said springs or elastic
bearings similarly disposed, thus affording great resiliency and ease for the rider.
If required, rubber washers or cushions may be used to form seatings in any of the
parts for the springs, and if required said springs may be surrounded by rubber or
other suitable sleeves to prevent any possibility of rattling, preferably however, I do
not use these additions, though I reserve to myself the right to do so in connection
with my improvements..
:
As previously stated, I may sometimes substitute rubber plugs or other springs. in
lieu of coiled springs, so as to provide elastic or resilient bearings, but preferably
coiled springs such as described will be employed.
I wish to state that I can modify or vary the details herein, more fully, described
as occasion may demand, to suit different requirements without departing from the
principle of my invention, but
י
Having now 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
Firstly. In cycles the anti-vibration arrangements. consisting of the particular
construction and telescopic arrangement in connection with the front fork of a cycle
frame adapted to receive. coiled, springs and operating in manner substantially as
described and shewn in Figures 1 to 7 of the accompanying drawings.
Secondly. In cycles the anti-vibration arrangements consisting of the particular
construction of diagonal back fork stay of a cycle frame adapted to operate somewhat
in a telescopic, manner in combination with a telescopic spindle surrounded by a
coiled spring secured within tubes forming the upper part of said back stay and
operating as and for the purpose, substantially as described and shewn on the
drawings.
Thirdly. In combination the method of jointing the diagonal back stay to the rear
lug of the frame by means of a shouldered pin and shouldered collar and screw nut as
described and shewn.
Fourthly. In combination with my improved construction and spring operating
arrangements for cycles, the method of jointing the horizontal lower members or back
stays of the frame to a false bridge in connection with the bottom bracket in manner
