Improvements in or relating to Pneumatic Tires for Bicycles.
CHARLES GENTLE of 214 East Jackson Street, in the City of Hamilton, in the
County of Wentworth in the Province of Ontario, Dominion of Canada, Cabinet
Maker, do hereby declare the nature of this invention to be as follows:-
My invention relates to a pneumatic tire having an annular recess or groove for
the insertion of an outer protection band, or ring, of well stretched and seasoned
leather or other suitable material impervious to the weather, the said groove and
band being continuous with the tire proper.
The objects of my invention are, first, to provide a pneumatic tire having an
annular band inserted therein in order to lengthen the life of the tire, second, to
replace a worn and old band with a new one without replacing the tire, third, to
afford protection to the face of the tire proper against punctures, and fourth,
to afford facilities for the proper insertion and securing of the band in position on
the tire.
Figure 1, is an enlarged sectional elevation of a pneumatic tire, showing especially
the annular and inclined side walls which form the annular groove, and the tire
protecting band inserted therein.
Figure 2, is a section of the detailed tire protecting band constructed in three
separate parts cemented together.
Figure 3, is an enlarged sectional elevation of a pneumatic tire, being a
modification of Figure 1, the annular side walls which form the annular groove
being in vertical line with the tire, and the tire protecting band provided with side
wire rings, in position in said groove.
Figure 4, is a section of the detailed tire protecting band having annular side
recesses for the insertion of wire rings.
The pneumatic rubber tire proper is indicated by A, and the tire protection bandi
by B. This tire has an annular recess or groove C, upon, or in its face, thus
forming a wall 2, on each side of the groove and continuous with the same, therefore
with the tire, and being a part thereof. This annular groove will be of sufficient
width and depth, and also of shape, to answer the particular requirements and
objects set forth. The band B, is inserted in position in its groove previous to
inflating the tire, which when inflated makes the band secure and as one with the
tire.
It will be observed that in the modification of the side walls of the groove, that
the walls may be constructed so as to widen the groove at its root into a dove-tail,
or the walls may be in vertical line with the tire as deemed most efficient. Providing
the walls are in vertical line, I purpose to insert a wire ring D, in a small annular
groove 3, formed in each edge of the hand and in close proximity to said edge.
The edges of the band may be stitched together in order to secure the wire rings,
if deemed necessary. These rings of wire prevent any possibility of the edges of
the band from leaving their position in the groove through any dampness or other
cause whatever.
On account of the circumference of the band being smaller at the outer edges
than in the centre, it will be necessary to have the outer side pieces of the band
less in circumference than the central part in order that the said band may conform
to and adhere close in position in the groove this feature would obviate the

page_text: necessity of using the above mentioned wire rings. The section of this band as
defined and seen in Figure 2, of the drawing, delineates the two outer edges 5, of
less circumference than the cental part in order to conform to the groove as herein
described.
The walls of the groove are of sufficient face to form a proper and lateral support
for the band, the most important element being, the annular and continuous groove
provided with a continuous band of suitable material secured therein, to engage
with the ground, substantially as set forth.

Charles GENTLE, of 214 East Jackson Street, in the City of Hamilton, in the
County of Wentworth, in the Province of Ontario, Dominion of Canada, Cabinet
Maker, 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 aud by
the following statement :-
My invention relates to a pneumatic tire having an annular recess, or groove,
for the insertion of an outer protection band or ring, of well stretched or seasoned
leather, or other suitable material impervious to the weather, the said groove and
band being continuous with the tire proper.
The objects of my invention are, first, to provide a pneumatic tire having an
annular band inserted therein in order to lengthen the life of the tire, second, to
replace a worn and old band with a new one without replacing the tire, third, to
afford protection to the face of the tire proper against punctures, and fourth,
to afford facilities for the proper insertion and securing of the band in position on
the tire.
I attain these objects by the device illustrated in the drawings left with the
Provisional Specification.
Figure 1, is an enlarged sectional elevation of a pneumatic tire, showing
especially the annular and inclined side walls which form the annular groove, and
the tire protecting band inserted therein.
Figure 2, is a section of the detached tire protecting band constructed in three
separate parts cemented together.
Figure 3, is an enlarged sectional elevation of a pneumatic tire, being a
modification of Figure 1, the annular side walls which form the annular groove
being in vertical line with the tire, and the tire protecting band provided with side
wire rings, in position in said groove.
Figure 4, is a section of the detailed tire protecting band having annular side
recesses for the insertion of wire rings.
Similar letters refer to similar parts throughout the several views:―
The pneumatic rubber tire proper is indicated by A, and the tire protection band
by B. This tire has an annular recess or groove C, upon, or in its face, thus
forming a wall 2, on each side of the groove and continuous with the same, therefore
with the tire, and being a part thereof. This annular groove will be of sufficient
width and depth, and also of shape, to answer the particular requirements and
objects set forth. The band B, is inserted in position in its groove previous to
inflating the tire, which when inflated makes the band secure and as one with
the tire.
It will be observed that in the modification of the side walls of the groove, that

page_text: the walls may be constructed so as to widen the groove at its root into a dove-tail,
or the walls may be in vertical line with the tire as deemed most efficient. Providing
the walls are in vertical line, I purpose to insert a wire ring D, in a small annular
groove 3, formed in each edge of the band and in close proximity to said edge..
The edges of the band may be stitched together in order to secure the wire rings,
if deemed necessary. These rings of wire prevent any possibility of the edges of
the band from leaving their position in the groove through any dampness or other
cause whatever.
On account of the circumference of the band being smaller at the outer edges
than in the centre, it will be necessary to have the outer side pieces of the band
less in circumference than the central part in order that the said band may conform
to and adhere close in position in the groove, this feature would obviate the necessity
of using the above mentioned wire rings. The section of this band as defined and
seen in Figure 2, of the drawing, delineates the two outer edges 5, of less circum-.
ference than the central part in order to conform to the groove as herein described.
The walls of the groove are of sufficient face to form a proper and lateral
support for the band, the most important element being, the annular and continuous
groove provided with a continuous band of suitable material secured therein, to engage.
with the ground, substantially as set forth.
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.
