Machinist do hereby declare the nature of this invention to be as follows:-
An additional or further Improvement in my foriner Invention No 6961 A.D 1896
by arranging an adjusting device on the inner coil of the coil spring used in in y
former invention so that the coil spring may be adjusted at any desired tension.
The adjusting device may be of several designs but I prefer to use a number of
slot holes arranged lengthways in the end of the inner coil of the coil spring which
holes make the adjustment on a peg fixed in a suitable position in the circumference
of the inner coil of the coil spring as used in my former herein before mentioned
Invention.
Dated this 17th day of November 1896.

Improvements in Tyres for Wheels.
I JOHN EDWARD ROGERS of 85 Sycamore Road Smethwick near Birmingham
Machinist, 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:-
Figs 1-2 and 3 of accompanying drawing shew sections of Tyre constructed
according to my former invention No 6961 A D 1896 with section of spring (F) varied
as claimed which variation in section will not in anyway interfere with the application
of my present improvements.
It will also be seen, that any variations of the section of the spring (F) can be used
in combination with my present invention other than the simple variations shewn
in Figs 1-2 and 3.
Fig 4 shews plan and elevation of the end of spring (F) prepared with a range of
holes (G) and (F) (F2) and (F).
This prepared end of spring (F) would be used as the inner coil of the spring (F)
when coiled up to form part of the tyre.
Fig 5 shews prepared end of spring (F) as shewn in Fig 4, coiled up, and fitted
with pins through holes (FI) (F) and (F), these pins have nuts on the ends on the
inside of the inner coil of spring (F) which nuts can be put on the pins or taken off
from the inside of spring (F) as shewn.

page_text: When the spring (F) is placed inside the flexible cover (A) to make up the tyre
the nuts are not on the pins that pass through the holes (F) (F2) and (F3), but when
the desired adjustment in spring (F) has been made, some of the range of holes (G)
will correspond with holes (F) (F) and (F3) the ends of the pins will come through
the holes (G) when the ruts can be put on the ends of the pins as shewn in Fig 5.
The number of pins for fixing adjustinent of spring (F) can be varied.
The device or method of fixing the adjustment of spring (F) may be varied without
departing from. the nature of my invention.
If desirable I may use only one coil in spring (F) plus the overlapping of the ends
required for adjustment.
Thus it will be seen that to carry out my invention I take a strip of steel of the
required section and length to give one or more coils on the inside circumference of
the covers as shewn in Fig 1-2 and 3 and for the purpose of making a permanent
tension in the one or more coils of spring (F) an adjusting device is used constructed
as shewn in Fig 4 & 5 for permanently fixing the diameter of the coil or coils used
in spring (F) for forming the tyre.
The range of holes (G) and (F1) (F2) and (3) when brought together in a circle
as shewn in Fig 5 show how the permanent adjustment is made by means of the pins
through the holes (F1) (2) and (FS) and holes corresponding with them in range (G)
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 The use in combination with spring (F) of a device or method for making the
adjustment of spring (F) permanent when arranged in flexible cover (A) and
forming a tyre substantially as shewn and described for attaching to the rim of
a Wheel.
