Improvements in and relating to Pneumatic Tyres for the Wheels
of Vehicles.
I, STUART VALENTINE GALLEY, of No. 1, The Pavement, White Post Lane,
East Ham, in the County of Essex, Draughtsman, do hereby declare the nature
of this invention to be as follows:-
My invention relates to certain improvements in pneumatic tyres for the
wheels of vehicles, and has for its object the attainment of perfect resiliency
without risk of puncture by contact with sharp substances.
In order that my invention may be the better understood I have appended
the accompanying sheet of drawings, in which Figure 1 is a transverse section
of one form of rim and tyre, and Figure 2 a similar section showing a modifica-
tion thereof. Figure 3 is a transverse section of a double or returned rim, to
which the tyre according to my invention is adapted.
In carrying my invention into effect I use a metal rim A of semi-circular
cross-section, enclosing a pneumatic tube B which may be inflated and deflated
in the ordinary manner. A pad C, of india rubber, insertion, compound, or any
resilient material or substance capable of withstanding the wear of traction, is
fitted into the rim A above the tube B, and is there retained by the annular
wings bb. When the tube B is inflated said wings bb are tightly gripped
by the shape of the rim A, and the air spaces a a' between said tube B and rim A
compensate the compression due to C being forced inwards by any inequality
of the road or track.
Thus the circular pad C bears all the wear and tear incidental to traction, and
yot possesses the necessary resiliency, and is to all purposes equal in effect to
the direct employment of the pneumatic tube upon the road or track. Figure 2
is a modification showing a tyre adapted to vehicles in which the traction is
heavier than that of ordinary velocipedes. Figure 3 shows the device applied
to a double or returned rim, and the letters of reference indicate corresponding
parts throughout the several views.
I may alter the configuration of the tyre according to my invention to suit
the requirements of various conditions of adaptation without departing from
the essential features thereof, which consist in the surrounding of a pneumatic
tube by a circular pad as shown.

I, STUART VALENTINE GALLEY, of No. 1, The Pavement, White Post Lane,
East Ham, in the County of Essex, Draughtsman, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:
-
My invention relates to certain improvements in pneumatic tyres for the
wheels of vehicles and has for its object the attainment of perfect resiliency
without risk of puncture by contact with sharp substances.
In order that my invention may be the better understood, I have appended
the accompanying sheet of drawings, in which Figure 1 is a transverse section
of one form of rim and tyre, and Figures 2, 3, and 4 are modifications thereof.
Figure 5 is a transverse section of a double or returned rim to which the tyre
according to my invention is adapted. Similar letters of reference indicate
corresponding parts throughout the several views.
In carrying my invention into effect I use a metal rim A. of semi circular
cross-section, enclosing a pneumatic tube B which may be inflated and deflated
in the ordinary manner. A pad C of india-rubber, insertion, compound, or any
resilient material or substance capable of withstanding the wear of traction, is
fitted into the rim A above the tube B and is there retained by the annular
wings. When the tube B is inflated, said wings bare tightly gripped
by the shape of the rim A and the air spaces a a¹ between said tube B and rim A
compensate the compression due to being forced inwards by any inequality
of the road or track."
Thus the circular pad C bears all the wear and tear incidental to traction and
yet possesses the necessary resiliency, and is for all purposes equal in effect to
the direct employment of a pneumatic tube upon the road or track. Figure 2
is a modification showing a tyre adapted to vehicles in which the traction is
heavier than obtains in the case of ordinary velocipedes. Figures 3 and 4 illus-
trate a modification in which the pneumatic tube B is formed upon, and is
integral with the pad C, and held within the rim A by inflation.
Figure 5 shows a modification of Figure 1 applied to a double or returned
rim A the manner of retention being the same as described with reference to
Figure 1.
The rims A may be modified in any of the examples, by carrying the edges
higher than is shown by the drawings, so as to embrace the pad above the
shoulders thereof.
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:-
:-
First. In a tyre for vehicles the combination of a pad C and wings 6 b¹, with
a pneumatic tube B and rim A substantially as herein described and shown by
the appended drawings.
Second. In a tyre for vehicles the combination of a pad C with a pneumatic
tube B of which it forms an integral part, fitted within a rim A by inflation
substantially as herein described and shown by the appended drawings.
Third. In a tyre for vehicles the construction and arrangement of the several

page_text: parts, substantially as and for the purposes herein described with reference to
the appended drawings.
Dated this 23rd day of May 1898.
