PROVISIONAL SPECIFICATION.
New or Improved Process and Apparatus for Connecting Together
the Ends of the Air-Tubes of Pneumatic Tyres.
I, GUSTAV KNODERER, of 12 Markstrasse, Lahr, Baden, in the Empire of
Germany, Mechanician, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a new or improved process for connecting together
the ends of the air-tubes of pneumatic tyres.
The accompanying sheet of Drawings illustrates this process and the apparatus
employed therein.
a
The process of connecting together the two ends of the air-tube, (in which
process a sleeve ao-Figures 4 to 8-that can be closed by sliding clamp 6 is
employed) is as follows:-
One end of the air-tube is introduced into any suitable apparatus, such as the
sleeve a for example closed by the sliding clamp b, so far that it projects beyond
the same about 5 centimeters; the projecting portion is then turned over and
stretched on to the outside of the sleeve, the end of the air-tube being thereby
drawn somewhat further through the sleeve. This operation is continued until
the tube overlaps the sleeve to the extent of about six centimeters. When this
has been effected, the stretched and turned-over end of the air-tube is folded
back, as shown at d in Figure 2, in such a manner that it extends about 2 to 3
centimeters backwards upon the first turned-over portion. This end of the air
tube being thus drawn on to the sleeve a, the other end c thereof is turned back
by hand about 2 to 3 centimeters, and is then drawn over the sleeve a until it
comes in contact with the end d of the tube, as shown in Figure 3.
The part c of the air-tube is then, by way of trial, drawn over d, as shown in
Figure 2, in order to ascertain whether it fully covers the part d, and is then
restored to the previous position shown in Figure 3. The part d is now smeared
over in the usual way with cement or solution, and then pressed or pulled forward
so that the two ends of the air-tube become joined to one another, as shown in
Figure 2. After the adhesive material has acquired the desired degree of hardness
and firmness, the sliding clamp 6 is drawn out of the sleeve and the now closed
tube can be easily removed from the sleeve through the slot therein.
Figure 1 shows the completely connected tube ends, the two parts c and d
being fastened together by means of any suitable adhesive material in the manner
above described.
Figure 2 shows the tube ends when connected together in the stretched position,
whilst Figure 3 shows the ends intended to be connected together, in the position
in which they are ready to have the adhesive material applied to the part c or d, or
to both such parts if required.
The object of the process is to effect a good air-tight connection of the two
ends, and this is secured by stretching them and laying them one over the other
free from folds or wrinkles, in the manner above described.

page_text: The sleeve, after being closed by the sliding clamp b, may be used as a receptacle
for the objects used in effecting repairs: For this purpose the two open ends
inay be closed by means of covers h, as shown in Figure 9.

New or Improved Process and Apparatus for Connecting Together
the Ends of the Air-Tubes of Pneumatic Tyres.
I, GUSTAV KNODERER of 12 Markstrasse Lahr, Baden, in the Empire of
Germany, Mechanician, 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 relates to a new or improved process and apparatus for connecting
together the ends of the air-tubes of pneumatic tyres
And in order that the said invention may be fully understood I will proceed to
describe the same with the aid of the sheet of Drawings filled with my Provisional
specification.
The process of connecting together the two ends of the air-tube, in which process
a sleeve a Figures 4 to 8-that can be closed by a sliding clamp 6 is employed
is as follows:
One end of the air-tube is introduced into any suitable, apparatus, such as the
sleeve a for example closed by the sliding clamp b, so far that it projects beyond
the same about 5 centimeters; the projecting portion is then turned over and
stretched on to the outside of the sleeve, the end of, the air-tube being thereby
drawn somewhat further through the sleeve. This operation is continued until
the tube overlaps the sleeve to the extent of about six centimeters. When this
has been effected, the stretched and turned-over end of the air-tube is folded
back as shown at d in Figure 2, in such a manner that it extends about 2 to 3
centimeters backwards upon the first turned-over portion.
This end of the air-tube being thus drawn on to the sleeve a, the other end c
thereof is turned back by hand about 2 to 3 centimeters and is then drawn over
the sleeve a until it comes in contact with the end of the tube, as shown in
Figure 3.
The part c of the air-tube is then, by way of trial, drawn over d, as shown in
Figure 2, in order to ascertain whether it fully covers the part d, and is then
restored to the previous position shown in Figure 3. The part d is now smeared
over in the usual way with cement or solution, and then pressed or pulled forward
so that the two ends of the air-tube become joined to one another, as shown in
Figure 2.
After the adhesive material has acquired the desired degree of hardness and
firmness, the sliding clamp b is drawn out of the sleeve and the now closed tube
can be easily removed from the sleeve through the slot therein.
Figure 1 shows the completely connected tube ends, the two parts c and d
being fastened together by means of any suitable adhesive material in the manner
above described.
Figure 2 shows the tube ends when connected together in the stretched position
whilst Figure 3 shows the ends intended to be connected together, in the position
in which they are ready to have the, adhesive material applied to the part cor d, or
to both such parts if required.

page_text: The object of the process is to effect a good air-tight connection of the two
ends, and this is secured by stretching them and laying them one over the other
free from folds or wrinkles, in the manner above described.
The sleeve, after being closed by the sliding clamp b, may be used as a receptacle
for the objects used in effecting repairs. For this purpose the two open ends
may be closed by means of covers h, as shown in Figure 9.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what I
claim is:-
First. The process for connecting together the two ends of the air-tube of a
pneumatic tyre which consists in drawing the two ends to be connected together
over a sleeve a, in applying adhesive material to the said ends, and in then placing
ene end over the other substantially as described.
Second. The apparatus for carrying into effect the process forming the subject-
matter of the first claiming clause hereof, which consists of a sleeve a slit
lengthwise and provided with a sliding clamp 6 or other suitable device, combined
and operating substantially as described.
Third. In the apparatus forming the subject-matter of the second claiming
clause hereof the arrangement of covers h on the sleeve a for the purpose of making
the said sleeve suitable as a receptacle for the objects employed in effecting
repairs, substantially as described with reference to Figure 9 of the Drawings.
Dated this 15th day of June 1897.
