Improvements in Pneumatic Tires for Velocipedes and other Vehicles.
We, RESTORE BIDDLE LAMB, of 418 Pearl Street, Camden, Inventor, and EDWARD
ZANE COLLINGS, of Laurel Springs, Cranberry Grower, both of New Jersey, United
States of America, 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 :-
The invention consists of an improved construction of guard or means for preventing
puncturing of the pneumatic tube of a bicycle tire.
The invention is illustrated in the accompanying drawing in which
Figure 1 represents a longitudinal section of a bicycle tire embodying the
invention.
and
Figure 2 represents a transverse section thereof.
Figures 3 and 4 represent opposite faces of the guard.
Figure 5 represents a transverse section of the guard, the parts being separated.
Figures 6 to 9 represent perspective views of different forms of guards employed
Figure 10 represents overlapping strips employed.
Similar letters of reference indicate corresponding parts in all the figures.
A designates the outer tube or cover of a bicycle tire, and B the inner tube thereof,
said outer tube or cover being divided so that it may be opened when desired, and
provided at the abutting edges with interlocking tongues C.
Interposed between the tubes at the tread portion thereof, is a guard D for
preventing puncturing of the inner tube, said guard consisting of the strips E, F, of
leather, preferably deer-skin, goat-skin, integument, or other tough material, and the
piece G of fabric, such as canvas muslin or the like, said strips E and F being on
opposite sides of the piece G and secured thereto by cementing or otherwise, more
particularly at their ends, said piece G being wider than the strips E, F, so that its
edges H may be cemented or otherwise properly secured to the inner face of the
tube A, thus preventing slipping or shifting of the guard from its position. The
strips E and F have their joints broken on opposite sides of the piece G as at J, K, so
that each joint is backed by the solid material of the opposite strip, whereby should a
tack or other article pass through a joint it will be resisted by said solid material, it
being noticed that the guard thus presents an effective means for preventing the
puncturing of the inner tube without materially adding to the thickness or weight of
the tire. The strips are sufficiently wide to guard the parts of the tube exposed to
piercing or puncturing, and the guard is not prevented from bending to accord with the
curvature of the tire in longitudinal and transverse direction. Moreover, the guard
s of a highly flexible nature, and it does not impart rigidity to the tire nor
materially affect the resiliency of the same.
In Figure 6, we show a strip of fabric F1 which has the leather G' secured
thereto in any suitable manner, preferably by the stitching H' along one edge
thereof.
The guard seen in Figure 6 is secured in position in substantially the same

page_text: manner already described with respect to the structure seen in Figures 3 and 4, it
being noted that by having a single edge of each strip secured thereto, the free
edges can slide slightly upon each other, so that there will be no puncturing.
In Figure 7, we show a single piece of leather K, which may be deer-skin or goat-
skin, and has the side tabs I attached together by means of which it is cemented or
otherwise attached or secured within the space existing between the tread of the
inner and outer tubes of the tire.
The guard seen in Figure 9 is substantially the same as the one seen in Figure 7,
except the strip M of leather or other suitable material is provided with the tabs N on
each side thereof for attachment to the desired point.
In Figure 8, we have shown the strip P of fabric provided with the tabs Q for
attachment to the desired point, said strips having the piece R secured thereto in
any suitable manner, as by the stitching S.
It will of course be understood from the foregoing that any one of the guards seen
in Figures 6 to 9 inclusive, may be substituted in place of the guard seen in
Figures 3 and 4, the principle of the invention being the same in each instance.
In Figure 10 we show overlapping strips T, U, of deer-skin, goat-skin or their
equivalents, which may be employed if desired.
Having now particularly described & ascertained the nature
invention and in what manner the same is to be performed, we declare that what
of our said
we claim is :-
1st. A non-puncturing guard for a bicycle tire consisting of the strips E and F of
tough material, and the piece G of fabric, said strips being on opposite sides of said
piece, the latter having its sides extended beyond the edges of said strips, forming
the attaching edges H, the joints of said strips being broken on opposite sides, and
the adjacent edges of the strips abutting forming a continuity of the strips on both
faces, and a uniform thickness of the guard throughout the length of the same.
2nd. A bicycle tire consisting of outer and inner tubes, the piece G of fabric with
its sides secured to said tubes, and strips E and F of tough material secured to said
strip on opposite sides thereof, the joints of said strips being broken on opposite faces 3
the edges of adjacent strips abutting, thereby forming a continuity of the strips on
both faces and a uniform thickness of the guard throughout the length of the same.
3rd. A guard for a bicycle consisting of the strips F1 G1 secured to each other by
stitching or other means along a single edge thereof, said guard being adapted to be
inserted in the inner and outer tube of a bicycle tire.
4th. A guard for a bicycle tire consisting of strips of leather and fabric or other
suitable material stitched or otherwise secured to each other along the edge thereof,
and tabs secured to one of said strips for securing the latter in the space between the
inner and outer tubes of a bicycle tire.
3
5th. The combination of the inner and outer tube of a bicycle tire, and a strip of 4
leather or other tough material having fastening tabs on either edge thereof, said
leather being adapted to be inserted between the treads of said tire.
6. The combination of the inner and outer tube of a bicycle tire with a strip of
leather, of deer-skin, goat-skin or equivalent between said tubes.
7th. The combination of the inner and outer tubes of a bicycle tire, with overlapping 4
strips of deer-skin, goat-skin, or their equivalents between said tubes.
