Improvements in Pneumatic Tyres and in Means for Attaching them
to Wheel Rims.
We, JOSEPH ANDREW BERGER, of 983, North Clark Street, Chicago, County of
Cook, State of Illinois, United States of America, Electrician, and JOHN PETER
LARSON, of 772, Sedgwick Street, in said Chicago, Tobacco 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 fol-
lowing statement:
Our invention has particular reference to a form of pneumatic tyre fasteners in
which the nipples for fastening the spokes to the wheel-rim are utilized for
removably securing the tyre-jacket to the rim.
In putting our invention into practice, we use a spoke-nipple having a head
thereon which engages with eyelets or sockets in the tyre-jacket.
The construction and operation of our device will be understood from the fol-
lowing description with reference to the accompanying drawings, in which:-
Figure 1 is a cross section of a tyre, a wheel-rim, and fastening means con-
structed according to our invention.
Figure 2 is a side view of part of the tyre and rim, partly broken away, and
in section on the line, a of Figure 1; showing the fastening means and the
position of the laps of the tyre-jacket from that view.
Figure 3 is a modification of the nipple and head, in which the head has a
threaded shank seated in the body of the nipple which is oppositely threaded.
Figure 4 is a cross section of part of the rim and tyre, partly broken away,
showing a modified form of the fastening means in which a spring-head on the
nipple engages with a socket in the inner lap of the jacket.
The body 1 of the nipple shown in Figures 1 and 2 has an integral neck 3
extending above the flange 2 and terminating in the head 4. The spoke S is
threaded to fit the nipple in the usual manner.
The rim 7 has therein, the usual recess 6 for receiving the bur 5 upon which
the flange 2 of the nipple rests.
The tyre jacket 10 has an eyelet 9, in its outer lap 10¹ and an eyelet 9¹ in
its inner lap 10".
The eyelets 9 and 9' are of the proper size to permit the head 4 to pass through
same.
The inner lap 10 of the tyre-jacket, has a strip 11 secured thereto for pro-
tecting the inner tube 12, of the tyre, against the head 4.
When the inner tube 12 is inflated, the laps 101 and 10", draw apart so that
the head 4 projects over. the rim of the eyelet 9¹, thus preventing the accidental
removal of the jacket.
When the inner tube 12 is deflated the lap 10" can be readily released from
the heads 4, at any part of the tyre.
All of the spoke nipples may be made as shown, but this will not be necessary,
since the tyre-jacket can be firmly held by attachment to nipples of our form
which alternate with nipples of the kind in ordinary use.

page_text: One of the main advantages of our construction, is that the inner lap of the
tyre-jacket may be released from its fastenings at any place where the inner tube
may be punctured. This will enable the operator to draw out enough of the
tube to mend same without disturbing the tyre-jacket, or removing same from
its fastenings, at other parts of the rim.
The modification shown in Figure 3 consists of an ordinary nipple. 11 interiorly
threaded, with the head 4 having the neck 3 the same as in the other form shown
in Figures 1 and 2, but having a threaded shank 3 adapted to be screwed into
the body of the nipple.
The object of this form is to utilize the form of nipples now in common use,
providing the head with a threaded shank for attachment thereto.
f
The modification shown in Figure 4, consists of a nipple which is in all
respects like that shown in Figures 1 and 2, except that the head 4 is made like
those in common use on glove fasteners; being made of thin resilient sheet-
metal. With this form of head I use a socket 9 such as is used on said glove
fasteners. This is fastened to the inner lap 10" of the tyre-jacket. The eyelet
for the outer lap 101 is like that shown in Figures 1 and 2.
We are aware that it is old to secure the laps of the tyre-jacket together by
means of studs and sockets similar to glove fasteners, and also that it is old to
secure the tyre-jacket to the rim by similar means. We are aware also, that
the spoke nipples have been used heretofore for fastening plates to the wheel
rim; said plates having sockets therein, near the sides of the nipples, for receiv-
ing heads or studs on the jacket. We therefore do not claim such construction
broadly.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that
what we claim is;-
(1) A spoke-nipple having a flange 2, and a neck, extending above said flange
of sufficient length to pass through. the outer lap of a tyre-jacket, and termi-
nating in a head, substantially as and for the purpose specified.
2. A spoke nipple having a flange, and a neck extending above said flange
of sufficient length to pass through the outer lap of a tyre-jacket, and termina-
ting in a head; in combination with a tyre-jacket having eyelets in the outer
and inner laps for receiving such head, substantially as described.
3. A spoke-nipple having an integral flange 2, and an integral neck extending
above said flange of sufficient length to pass through the outer lap of a tyre-
jacket, and terminating in a head, substantially as and for the purposes specified.
4. A spoke-nipple having an integral flange 2, and an integral neck extending
above said flange of sufficient length to pass through the outer lap of a tyre-
jacket, and terminating in a head, in combination with a tyre-jacket having
eyelets in the outer and inner laps, for securing said. head, substantially as
described.
5. A spoke-nipple having an integral flange 2, an integral neck 3 extending
above same and terminating in an integral head 4; in combination with an inner
pneumatic tube 12, and a tyre-jacket having the eyelets 9, 91 in its laps, adapted
to pass entirely below said head and engage the neck and head when said inner
tube is inflated; substantially as described:
