Vehicles.
I TIMOTHY MURPHY of Number 73 and 74 Main Street Clonmel in the
County of Tipperary Agricultural Engineer do hereby declare the nature of this
invention to be as follows:-
The said improvements consists of a band composed of steel or other material
said band being made larger than the wheel and is attached thereto by several pins
which are fitted to said band at one end and said band is free to move on ends of
said pins. The other ends of said pins passes through holes formed in or through
rim or socket attached to rim of said wheel at any given distance apart around the
circumference. Upon each of said pins are placed two spiral springs, said springs having
a collar between them and said collars are being connected to said pins and when so
placed as aforesaid are kept confined in said holes or socket of rim of said wheel by
suitable stops at the ends of said holes or sockets. As said wheels revolve they
will be suspended at the top part by the springs next the rim pressing against the
said collars on said pins and supported next the bottom by the springs at the other
side of the collar next the end of pin or said spiral springs may be placed on said
pins one inside and one outside said rim of wheel in which case there are collars on
said pins outside the ends of said springs, said rim of wheel serving as central collar
between them in which case said wheel is suspended at the top by the springs
inside rim of wheel and supported at the bottom by the springs outside rim of
wheel.

"E" is the band which is attached to ends of said pins "B" by the flanges "A"
on which they are free to move. The spiral springs are placed on said pins "B"
in said sockets "F" at "CC" having said collar "S" between them which said
collar is connected to pin "B." Said springs are confined in said sockets "F"
by the rim "D" at one end and the stops connected to socket "F" at "M" at the
other end.

tube "T" and said tube is screwed on said pin "B" and by being so screwed up
and down the tension of said spiral springs can be adjusted. "M" is the nut or
stop screwed into the socket "F" as shewn in drawing Figure 1, to adjust the
spiral springs.

I TIMOTHY MURPHY of Number 73 and 74 Main Street Clonmel in the
County of Tipperary Agricultural 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 :-
The said improvements consists of a band composed of steel or other
material said band being made larger than the wheel and is attached thereto
by several pins which are fitted to said band at one end and said band is
free to move on ends of said pins. The other ends of said pins passes
through holes formed in or through rim or socket attached to rim of said
wheel at any given distance apart around the circumference. Upon each of said
pins are placed two spiral springs, said springs having a collar between them
and said collars are being connected to said pins and when so placed as aforesaid
are kept confined in said hole or socket of rim of said wheel by suitable stops at the
ends of said holes or sockets. As said wheels revolve they will be suspended at the
top part by the springs next the rim pressing against the said collars on said pins
and supported next the bottom by the springs at the other side of the collar next
the end of pin or said spiral springs may be placed on said pins one inside and
outside said rim of wheel in which case there are collars on said pins outside
the ends of said springs said rim of wheel serving as central collar between them in
which case said wheel is suspended at the top by the springs inside rim of wheel
and supported at the bottom by the springs outside rim of wheel as per drawings
left with Provisional Specification which we now adopt and of which

."D" is the rim of said wheel. "B" are the pins passing freely through holes in
said rim and through the sockets "F" said sockets being fastened to said rim.
"E" is the band which is attached to ends of said pins "B" by the flanges
on which they are free to move. The spiral springs are placed on said pins "B"
in said sockets "
* F at "CC" having said collar "S" between them which said
collar is connected to pin "B." Said springs are confined in said sockets "F" by
the rim "D" at one end and the stops connected to socket "F" at "M" at the
other end.

said flange formed on band "E." The end of said pin "B" is fitted on flange "A"
on which it is free to slide. The collar "S" is connected to the tube "T" and
said tube is screwed on said pin "B" and by being so screwed up and down the
tension of said spiral springs can be adjusted. "M" is the nut or stop screwed

pass.
Drawing Figure 4 is a sectional and supplemental drawing (to those lodged with
Provisional Specification) of said wheel and spring band wherein is shewn one of
the said other forms of springs which can be used cojointly with the said spiral
springs as herein before stated. "P" is a twitch or leaf spring fastened on to rim
of wheel at "Y," the other end is jointed to the sliding part "K," and said
part "K" is grooved and said groove grips the flange of spring band "U" on
which it is free to slide as hereinbefore mentioned and illustrated in drawings

page_text: Figure 1 and Figure 2 left with Provisional Specification. "R" is a pin connected
to twitch or leaf spring "P" and passing through rim "d" of said wheel.
Said spiral spring is placed on said pin "R" between the rim "d" and the twitch
or leaf spring "P" and as so placed will assist the twitch or leaf spring "P" in
resisting the pressure of said wheel towards the said spring band. Or said twitch
or leaf spring "P" may be fastened to said spring band in which case said sliding
part "K" would be made to slide on rim "d" of said wheel in which case results
similar to those had by the first mode explanatory of drawing Figure 4 would be
obtained.
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. That by adopting the said invention as hereinbefore described sudden vibration
or jerking of bicycles or other vehicles is prevented while travelling on uneven
surfaces said vibration being prevented by the action of the springs which are
placed around in connection with said band and rim of said wheels thereby assuring
to bicycles or other vehicles protection by reason of being drawn with greater
ease.
2. That the jerking is controlled or checked where it first originates.
3. That the said invention can be applied to all road vehicles no matter what
burden such vehicle may be intended to carry.
