COMPLETE SPECIFICATION.
Improved Tire Repairing Device.
1, DAVID HAXTEN Cox Jr. of the City of Elizabeth, State of New Jersey,
United States of America, Gentleman, do hereby declare the nature, of my
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 relates to devices for repairing pneumatic bicycle tires and the
like, and the object is to provide a device of this character of a simple and
inexpensive nature, of a light and compact construction and adapted for repairing
tires in a convenient and rapid manner.
The invention consists in a tire repairing device comprising a body and a conical
sleeve fitting on and removable from the body, said device having a pointed end
adapted for insertion in a puncture to be plugged and said sleeve serving when
inserted in the punctured tire as a conduit for the cement and plug by means of
which the tire is to be repaired.
The invention also contemplates certain other novel features of the construction
and combinations and arrangements of the various parts of the improved tire
repairing device whereby certain important advantages are attained and the device
is made simpler, cheaper and otherwise better adapted and more convenient for use
than various other similar devices heretofore employed, all as will be hereinafter
fully set forth. The novel features of the invention will be carefully defined in
the claims.
In order that my improvements may be the better understood, I have illustrated
in the accompanying drawings a tire repairing device constructed in accordance
with my invention, in which drawings
Figure 1 is an elevation of the device complete, and
Fig. 2 is a view similar to Fig. 1, hut showing the conical sleeve of the device in
section.
Fig. 3 is a perspective view showing the conical sleeve detached, and
Fig. 4 is a detached perspective view showing the removable point or cap of the
body.
Fig. 5 is a view showing a rubber tire plug adapted for use in connection with
my improved repairing device.
In these views, 1 indicates the sleeve of the device which is by preference, of
metal and made tubular and conical having one end 2 made smaller than its opposite
end 3. This conical sleeve has imperforate sides and in it is adapted to be inserted
the body 4 which is of wood, by preference, also made conical but having its larger
end 5 enlarged to form a handle at the base of which is formed an abrupt
shoulder 6 adapted to engage the edges of the larger end 3 of the conical sleeve I
when the body is inserted therein.
At its smaller end, the body 4 is provided with a rounded metal shank 7 secured
in place by means of a ferrule 8. The end portion of the shank 7 is made tapered
as shown at 9 in Fig. 2, and at the base of said tapered end portion is formed a pin
like extension 10 of less diameter than the body portion 7 of the shank but
aligned therewith and having a blunt or rounded point as clearly shown in the
drawings.
The extension 10 is adapted to fit in an aperture or recess formed axially in the
end of a cap or point 12 of a diameter substantially the same as that of the shank 7,
said aperture being shown at 11 in Fig. 4, and said cap 12 is split or transversely

page_text: slotted at its upper portion wherein the recess 11 is formed as is clearly shown in
Fig. 4, which is a detail view of this part. The sides of the cap 12 by reason of
this slitted construction, act as springs to hold the cap securely in place of the
reduced extension 10 of the shank.
The cap 12 is pointed as shown at 14 at its end opposite to the aperture 11 and
the proportions of the parts is such that when the body 4 is in place in the conical
sleeve with the shoulder 6 abutting on the edge of the sleeve at the larger end
thereof, the pointed end 14 of the cap 12 when held on the reduced extension 10 of
the shank will protrude slightly beyond the smaller end 2 of the said sleeve. The
point 14 of the cap 12 will, of course, be somewhat blunt.
When the parts are in this position, as shown in Figs. 1 and 2, the pointed end 14
of the cap 12 may be inserted in the puncture in the tire, and the tool then pressed
through the tire, being turned back and forth in the hand until the smaller end 2
of the sleeve shall have been worked through the tire so as to be held therein by
the elasticity of the material whereof the tire is composed.
. When this has been accomplished, the holy 1 of the tool is removed from inside
the sleeve, carrying with it the cap 12 and it will be seen that the sleeve forms a
conduit through which a quantity of cement may be injected into the tire, sufficient
to cement the plug therein. In order to hold the cement in place when poured into
the sleeve, said sleeve will be pressed at its smaller end against the side of the tire
opposite to the tread, and to permit the liquid cement to pass readily out into
close contact with the inner side of the tire tread, I provide the sleeve 1 adjacent
to its smaller end 2 with small lateral perforations 15, by preference three in
number.
The cement having been poured into the sleeve, the rubber plug with which the
repair is to be effected will be also placed inside the sleeve. By preference, plugs
such as that shown in Fig. 5, will be employed, each plug being formed with a
recess or aperture 16 in its stem and adapted for the insertion of the reduced
extension 10 of the shank and in inserting the plug, the extension 10 will be inserted
into said aperture 16 and the plug held thereon will be pushed head first down
through the sleeve 1.
The cement in the sleeve 1 will act as a lubricant to facilitate the passage of the
plug therethrough, and in this way, plugs of different sizes may be inserted through
the one, sleeve, making the tool serviceable for effecting all ordinary repairs. The
plug will be pushed through the sleeve until its head protrudes through the
smaller end 2 of the said sleeve, and stands in position to bear against the inside
surface of the tire around the puncture, after which the tool will be withdrawn,
leaving the stem of the plug protruding outside the tire.
To permit the sleeve to be conveniently locked to the body I prefer to provide
at the larger end of the body a pin 17 in position to engage an L-shaped or bayonet
slot 18, in the larger end 3 of the sleeve. In this way the parts are conveniently
held together while not in use, and the body is permitted to be locked inside the
sleeve in case it is desired to leave the tool standing in the tire after the plug has
been inserted.
The device constructed as above described is extremely simple and inexpensive
and is especially well adapted for use in repairing bicycle and similar pneumatic
tires, since it is compact and light and of a form adapted to be conveniently carried
in the pocket or tool bag. It will also be obvious from the above description that
the device is susceptible of considerable modification without material departure
from its principles and spirit and for this reason I do not wish to be understood as
limiting myself to the precise farm of the parts herein set forth.
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 :-
1. A tire repairing device comprising a body and a couical sleeve adapted to fit
thereon, said body having one end portion adapted to project from the smaller end

tially as set forth.
2. A tire repairing device, comprising a body and a conical sleeve adapted to fit.
thereon, said body having its end portions arranged to project from the opposite-
ends of the sleeve when the body is in the sleeve, the end of the body which

other end of the body being pointed and adapted for insertion in a puncture to be
plugged, substantially as set forth.
3. A tire repairing device comprising a conical sleeve, a body adapted for
insertion therein and a cap detachably connected to the body, and adapted when
the body is in the sleeve, to project beyond the smaller end of the sleeve, said cap
