PROVISIONAL SPECIFICATION.
Improvements in and in connection with Pneumatic Tyres for
Bicycles and other Vehicles.
HARRY WILSON TURNER Engineer 37, Broughton Road Stoke Newington N.
do hereby declare the nature of this invention to be as follows:—
My invention relates to improvements in pneumatic tyres, and the object of my
invention is to obtain increased resilliency and greater speed and comfort than has
hitherto been obtained by any of the well known methods of construction hitherto
employed in the manufacture of tyres of this description.
In carrying out my invention I provide a means of limiting the expansion of the
india rubber tube, or air-bag, in a lateral direction when the same is placed in
position on the rim of the wheel and inflated, and at the same time allowing it
greater elasticity circumferencially.
I attain the object of my invention by employing in lieu of the ordinary canvas
lining of the outer cover, a lining of elastic webbing, such as that used for elastic-
side boots, or some such similar material the elasticity of which is only possible in
one direction, or I may incorporate the said elastic material with the outer cover
or embed it therein.

Improvements in and in connection with Pneumatic Tyres for
Bicycles and other Vehicles.
I, HARRY WILSON TURNER of 27 Walbrook, in the City of London, E.C.,
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 :-
My invention relates to improvements in the construction of pneumatic tyres, as
used upon the wheels of bicycles, tricycles and similar velocipedes, and has for its
object, to obtain increased resiliency, and consequently greater speed, of the
machine, and comfort to the rider or riders, than has hitherto been obtained by
any of the well known methods of construction hitherto employed in the
manufacture of tyres of this description.
In carrying my invention into effect I employ, (in lieu of the ordinary canvas)
elastic webbing, such as that used in the manufacture of side spring boots, as a
lining for the outer cover or envelope of the gas or air bag, which I cement or
otherwise connect thereto in such a manner, that the elastic threads of the said
webbing are in line with the circumference of the wheels, while the non-elastic
threads of same are disposed laterally or crosswise, or transversely of the tread of
the wheel. By this means the expansion of the india rubber tube or air bag, in a
lateral direction, when the same is placed in position on the rim of the wheel and
inflated is limited by the said non-elastic threads of the lining of the envelope,
while at the same time the elastic threads of the said lining permit a graceful
elasticity of the tyre longitudinally or circumferentially of the wheel, which
operates fully in preventing vibration being felt by the rider or riders, when the
wheels are passing over stones or other obstructions lying within the track of. the

page_text: machine, while the non-elastic or cross threads of the said lining, would operate
materially in maintaining the lateral rigidity of the tyres when the machine is
canted, as obtains when the wheels are describing short curves.
The same elastic webbing or one way elastic material, may be advantageously
employed for the purposes stated, by embedding this within or upon, or in any
suitable manner incorporating it with the substance of the said outer cover or
envelope during the manufacture of the same.
For the purpose of strengthening the edges of the said one way elastic lining of
the outer cover, and permit these to be employed for carrying the usual wires or
cords (when such are used) by which the said covers are connected to the rim, I
may bind the said edges with canvas, leather, cloth or any other suitable material
adapted for the purpose, which may be fixed as stated by the means of solution or
other suitable cement, or by that of stitching, or both as may be found most
convenient.
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
1st. In the construction of the outer covers or envelopes of pneumatic tyres,
the employment of elastic boot-webbing, substantially as and for the purposes
herein set forth and described.
2nd. In the manufacture of pneumatic tyres, the combination with the outer
cover or envelope, of any suitable one way elastic material or elastic boot-webbing
the elastic threads of which are disposed or arranged longitudinally, while the non-
elastic threads are disposed transversally, in, on or otherwise with the said cover or
envelope, and with or without the edges of the said one way elastic material being
bound with canvas, cloth, leather or the like, and arranged to carry rods or cords,
substantially as and for the purposes herein described.
Dated this 22nd day of October 1894.
