PROVISIONAL SPECIFICATION.
A New or Improved Detachable Method of Securing Pneumatic
Tyres to Carriage Wheels and other Vehicles.
I, PATRICK JOSEPH CARBERRY, of 41 Upper Wellington Street, Dublin,
Ireland, Carriage Builder, do hereby declare the nature of this invention to be as
follows
This invention has reference to a new or improved method of securing pneumatic
tyres to carriage wheels and other vehicles, whereby the tyres are rendered readily
detachable in case of puncturing or bursting.
In carrying out my invention I propose to deal with the ordinary shod wheel as
follows:-
:-
Around the steel rim I place a band of india-rubber or other suitable material,
and of convenient thickness, and around this band I apply the steel channel rim
carrying the pneumatic tube, the tube being formed and attached to the channel
rim in the ordinary manner.
As thus built up I next tap from the inner circumference of the wooden felloe,
radial apertures through the several rims, that is, through the wooden felloe, the
steel rim, the india-rubber band, and the tube carrying rim,-and through these
apertures I screw threaded bolts provided with fixed fly heads, whereby the tube
carrying rim is firmly bound to the original wheel.
I may use around the circumference of the wheel three or more of these radial
bolts according to requirements.
As thus constructed it is obvious that in order to remove the pneumatic tyre it
will only be necessary to unscrew the radial bolts until the tube carrying rim is
released when the tyre can be readily removed.
Dated this 8th day of April 1895.

A New or Improved Detachable Method of Securing Pneumatic
Tyres to Carriage Wheels and other Vehicles.
I, PATRICK JOSEPH CARBERRY of 41 Upper Wellington Street, Dublin,
Ireland, Carriage 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:—
This invention has reference to a new or improved method of securing pneumatic
tyres to carriage wheels and other vehicles whereby the tyres are rendered readily
detachable in case of puncture or otherwise.
In carrying out my invention I propose to deal with the ordinary shod wheel, or
I may deal with a specially prepared wheel as hereinafter more fully described.
Around the steel rim of the ordinary prepared wheel I place a band of india-

page_text: rubber or other suitable material, and of convenient thickness, and around this band
I apply the steel channel rim carrying the pneumatic tube which latter is formed
and attached to the channel rim in the ordinary way. As thus built up I next tap
from the inner circumference of the wooden felloe, radial apertures through the
several rims, that is, through the wooden felloe, the steel rim, the india-rubber band,
and the tube carrying rim, and through these apertures I screw threaded bolts
provided with fixed fly heads, whereby the tube carrying rim is firmly bound to the
original wheel.
may use around the circumference of the wheel three or more of these radial
bolts according to requirements.
In order that my said invention may be more readily understood, I will describe
the accompanying drawings in which
Fig. 1, represents an ordinarily constructed carriage wheel shewing my invention
applied thereto. Fig. 2, is a cross section of same; and Fig. 3 a cross section
shewing modification of my invention
:-
a, is the wooden felloe; b, the ordinary steel rim; c, the band of india-rubber; and
d, the channel rim carrying the pneumatic tyre e, f, are the radial bolts which are
screwed from the internal circumference, and bind the complete tyre firmly and
securely in one solid mass.
It is obvious that upon the withdrawal of these radial bolts the pneumatic tube
with its channel rim can readily be removed and the wheel used as in its ordinary
condition.
It is also obvious that my invention can be conveniently applied to wheels
constructed without wooden felloes as illustrated in Fig. 3.
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 :-
First. In the construction of pneumatic-tyred wheels for carriages and other
vehicles, the method of securing the air tube rim to the metal rim of an ordinarily
constructed wheel by means of radial bolts in the manner substantially as herein
specified.
Second. In the construction of pneumatic tyred wheels for carriages and other.
vehicles, the method of securing the air tube rim to the metal rim as applied direct
to the spokes when the use of the ordinary wooden felloes is dispensed with, in the
manner substantially as illustrated and set forth.
Dated this 9th day of January 1896.
