PROVISIONAL SPECIFICATION.
New or Improved Means for Repairing Pneumatic or Inflated Tyres,
Beds, Pillows, Life Buoys, Cushions, Balls, and the like.
We, AARON SMITH CARTWRIGHT of 75 Ford Street, in the City of
Birmingham, Manufacturer, and ALFRED BLACKWELL of Icknield Street,
Birmingham aforesaid Cycle Manufacturer, do hereby declare the nature of this
invention to be as follows:-
This invention has reference to pneumatic or inflated articles, such for example
as wheel tyres, beds, pillows, life buoys, cushions, balls and the like, and relates to
a means whereby the same are repaired or made good, when punctured or pierced,
consequent upon coming in contact with any sharp instrument or protuberance.
Hitherto inflated or pneumatic articles, such as above set forth, have been repaired
or made good, when punctured or pierced as aforesaid, by a patch or covering-up
piece, being cemented, onto to the outside and over the injured portion of the article
or articles being repaired, which is found to be defective, inasmuch as the air, when
under compression, has a tendency to force off the patch or covering-up piece from
the said injured portion.
The object of my invention is to repair any such punctured or pierced article, as
stated, from the inside or interior of it, and consists in introducing into the said
interior, a patch or covering-up piece, of fabric, rubber, fabric faced with rubber,
or any other suitable material, and which said patch or covering-up piece, is kept in
position, over the puncture or piercing, by means of a small shank or stalk, (which
is fixed onto the patch or covering-up piece) taking into the puncture or piercing
as aforesaid, and the air in the interior which is under compression, forcing the said
patch against and over the said piercing or puncture.
In carrying out our invention in connection with a pneumatic or inflated hollow
wheel tyre, which has been previously pierced or punctured, and the compressed air
allowed to escape therefrom we enlarge the said piercing or puncture, and form it
preferably into a circular hole, by means of a suitable punch, and which hole is
afterwards filled up as hereinafter described.
We then take a patch or covering-up piece, of any suitable material, and of the
size required, provided with a shank, stalk or handle part, fixed in the centre
thereof, and made in one piece with it, and of a sufficient length to conveniently
take hold of, and of a diameter a little less than that of the punched hole of the
puncture.
The patch or covering-up piece is then folded or turned back, onto and around
said stalk, shank, stem or handle, alike unto the closing of an umbrella, and is then
passed through the prepared punched hole in the tyre as aforesaid, into the interior
of the hollow wheel circumference or tyre, when the said patch or covering up
piece automatically opens itself out, (being made partially of rubber) alike unto an
umbrella opened.
The covering up piece is then pulled towards, the inside face of the periphery of
the tyre, and the latter is then inflated or blown up, to an extent sufficient for the
purpose required, when the covering-up piece is automatically forced against the
inside face as aforesaid, by the great pressure of the air in the interior.
The stalk or handle is then cut off flush with the periphery of the tyre and fills
up the hole or piercing, which seals up the punctured or damaged part of the wheel
circumference.
If necessary a suitable solution or cement may be used on the acting face of the
covering-up piece, and in this case, the stalk or shank may be disconnected from

page_text: the covering up piece, after the same has been placed in position over the pierced
or damaged part.
The shank stalk or handle part when required for filling up the piercing is
preferably made of rubber, but the same may also be made of wood, ivory or metal
and may be disconnected when the covering-up piece is in position as described.
Although we have described the carrying out of our invention only in connection
with a wheel tyre, yet the same differs in no essential respect, as when applied to
all kinds of pneumatic or inflated articles.

COMPLETE SPECIFICATION.
New or Improved Means for Repairing Pneumatic or Inflated Tyres,
Beds, Pillows, Life Buoys, Cushions, Balls, and the like.
We, AARON SMITH CARTWRIGHT, of 75 Ford Street, in the City of Birmingham,
Manufacturer, and ALFRED BLACKWELL, of Icknield Street, Birmingham, afore-
said, Cycle Manufacturer, 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 the repairing of inflated and inflating articles, such
for example as pneumatic cycle tyres, air beds and pillows, life-buoys, footballs,
and other articles of a kindred nature, and the primary object of my invention is
the making good of such articles, on the same being punctured, cut, burst or other-
wise injured or rendered unsound.
In carrying out our inveution, we will describe same first in connection with the
repairing of a punctured single tube pneumatic tyre.
Figure 1 of the accompanying drawing represents a portion of a punctured or
cut pneumatic tyre.
Figure 2 represents a tyre with the puncture or cut, and the surrounding material
of the same, being removed by a wad cutter or circular cutter punch so as to leave
a clear and symetrically formed hole of a given size, which is, as hereinafter
described, filled up by the part of the stalk (a little larger in diameter than the
said hole) of a patch interiorly applied.
Figure 3 represents the said tyre, showing the hole or piercing, after the removal
of the perforating or cutting out tool, as shown in operation in Figure 2.
Figure 4 represents a vertical section of the plug patch and its stalk.
j
Figure represents the position of the patch, prior to its introduction into the
interior of the tyre, after the walls of the tyre, contiguous to the piercing, have
been properly cemented.
Figure 6 represents a threading of the umbrella-like patch through the hole into
the interior of the tyre.
Figure 7 represents the same passed through and affixed in position, after the
opening out of the patch or disc part, and the drawing of the same by the pulling
forward of the stalk, which is subsequently removed, by cutting, flush to the
surface of the tyre.
Figure 8 represents the stalk or plug part cut off flush to the tyre, and. a
covering patch placed over the joint formed by the connection.
Figure 9 is an outside view of the repair.
Figure 10 represents the patch applied to a Dunlop tyre, or one having an inner
cube enclosed within an outer one.
as a pneumatic tyre, b is a rim, and a² represents a puncture or cut within the
Baid tyre.

page_text: In Figure 2, c is a wad cutter shown cutting away the material around the
puncture or cut, and leaving a circular hole, which is marked a³ (see Figure 3) and
which is subsequently filled up with the bollow stalk of the mending patch as
hereinafter described.
In Figure 4, d is a plug patch of india rubber or other suitable material, with
a patch or disc end d³, a hollow stem d³, and a solid lower end or inside
thickening d'.
The tubular construction of the stem is for the purpose of introducing within it,
a ram or carrier e (see Figures 5 and 6) for the pushing of the patch part of the
combined plug patch home through the hole a³, as represented in Figure 6; then
on the same being pushed inwardly to an extent that the edges of the plain surfaced
patch are clear of this hole, the said patch expands or opens out flat, when by the
pulling back of the said patch by the tubular stem d³, the same is brought against
the inner side of the walls of the tyre, as represented in Figure 7, and as the said
inner walls covered by the patch, and comprehending the inner part of the stem,
were previously cemented, as marked f,, the said plug patch is affixedly held in
position.
To make the said hollow stem of the plug patch solid, a cemented closer plug g,
is then introduced. Then by cutting down the plug, flush with the periphery of
the tyre, and covering over the shorn end of the plug or stem, by an outside and
cemented patch h, as represented in Figure 8, the tyre is thereby repaired and
a sound patching accomplished.
In Figure 10, the patch comes between the outside of the inner tube and the
inside walls of the outer tube of the tyre, assuming that both tubes have been
punctured, and the outer one wad cut, to permit of the introduction of the patch,
so that the one patch mends at the same time both the inner and outer tubes, by
the prior cementation of the patch on all sides.
In carrying out our invention in connection with a rent, we pierce a series of
contiguous holes, and place a series of plug patches within them, and with the patch
parts overlapping each other, and with a continuous patch or a series of outside
patches applied to the outside plugs, which fill up the holes made.
It will be understood that the tubular construction of the stem admits of the walls
of the same falling to the sides of the pushing-in stem or mandril e, and thereby allows
the folding patch 2, to take up less room than it would otherwise do, and so pass
through a made hole whose diameter is of a less size than the cross section of the
stem, and further, it will be understood that the patch may be forcibly forced
against the part to be repaired by the blowing up of the tyre immediately on
the repair.
The patch may be of caoutchouc, vulcanized rubber, prepared canvas, silk or
other like materials.
It is understood that the operation of repairing is conducted when the tyre is
completely deflated.
The application of our improvements to the repairing of air beds and cushions,
the rubber interiors of footballs and other articles of a kindred nature differs in
no essential respect from its application to the repairing of a tyre as described.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
First: An inflating or inflated article repairing patch, consisting of a hollow
stalk or plug, having upon one end a flexible plain surfaced patch or disc, as
set forth.
Secondly-The combination with the inside walls of an inflating or inflated
article, of an expanding repairing patch d², with or without the inside thickened
part d', as set forth.
Thirdly-In an inflating or inflated article repairing patch, the combination

page_text: with an inflating or inflated article, of a plug patch d³, d³, d', and filling-in plug g,
as set forth.
Fourthly-In an inflating or inflated article repairing patch, the combination
with an inflating or inflated article, of a plain surfaced repairing patch d', d³, g, h,
as set forth.
