Improvements in or relating to Tires for Wheels of Vehicles.
I, HERBERT JOHN HADDAN, of the Firm of Herbert Haddan & Co., of 18,
Buckingham Street, Strand, W.C., London, Consulting Engineer, do hereby
declare the nature of this invention a communication to me from abroad by
Frank Wilbur Kinney, Edgar Arnold Hill and Raymond Beach Price, all Manu-
facturers, of Montauk Building, Chicago, Illinois, United States of America,
and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement:-
-
In fastening the ends of the wires or bands used in the manufacture of elastic
tires for vehicles, it is important that the joints shall be such as not only to hold
the ends of the wire or band against tensile strain but also to prevent any
lateral movement of the wire which would tend to speedily chafe and destroy
the tire at such point. The present invention is designed to provide a joint
fastener for tire wires or bands that shall not only securely hold together the
opposing ends of the wire or band against tensile strain, but shall securely retain
such parts against any danger of lateral shift incident to the strains that are
thrown upon the wire or band in use.
The invention consists in the joint fastener hereinafter described, illustrated in
the accompanying drawing and particularly pointed out in the claim at the
end of this specification.
Figure 1 is a perspective view showing part of an elastic tire with its retaining
wire or band and having my improved fastener applied thereto. Fig. 2 is a view
in vertical longitudinal section through a portion of the clastic tire showing the
wire or band made by my improved fastener. Fig. 3 is a view in vertical cross-
section on line 3-3 of Fig. 2. Fig. 4 is a detail perspective view of one of the
sections of my improved joint fastener. Fig. 5 shows a modification.
A designates the body of the rubber tire through which will extend a retain-
ing wire or band B. The body of the band B is formed of the longitudinal
thickened edge portions b, b united by a thinner central web thereby forming
central channels at opposite sides of the band or wire between its thickened
portions. Each of the ends of the wire or band is formed with one or more
holes adapted to receive retaining pins c that pass through the web and pre-
ferably the pins c are formed integral with one of the sections C or C¹ of the
fastener. Each of the sections C and C¹ of the fastener is formed with inwardly
extending lateral edges c and with a central rib 2. The central rib c² of each
section of the fastener will correspond in contour with the channel upon the
adjacent side of the band and the inwardly turned flanges c¹ will extend partially
around the thickened edge portions of the wire or band. In order to join the
ends of the wire or band B they will be brought together as shown in Figs. 1
and 2 and the sections C, C¹ of the fastener will be placed upon opposite sides of
the ends of the tire or band, with the pins e passing through the central web
of the wire or band. The free ends of the pins c will then be upset or headed
as at (Fig. 3) and will serve not only to securely unite the ends of the wire or
band B but also to rigidly clamp the sections C, C' of the fastener in position.

page_text: When the fastener is thus in place the central rib of each section, and the in-
wardly extending flanges c¹ will securely hold the ends of the retaining wire
or band B against all possibility of lateral movement, thereby giving to the wire
or band B the effect of a continuous ring. In practice I prefer to form the
sections C, C¹ of the fastener of drop forgings, although manifestly this is not
essential. If the band B be formed with thickened portions and a channel on
one face only, then obviously only one of the sections of the fastener need be
formed with the central rib ..
18.4
In the modification shown in Fig. 5 of the drawing, the inner face of one of
the fastener sections is shown as provided at each side of the central rib with
transverse ribs that will be embedded in the thickened edge portions 6 of the
wire or band B when the fastener sections are in place thereon. These transverse
ribs not only increase the tensile strength of the joint but also give greater
lateral strength thereto. The transverse rib c may be formed on one or both of
the sections of the fastener.
.1
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. In a vehicle tire, the combination with the retaining band or wire B having
thickened portions and channels upon one or both sides and having its ends
provided with holes to receive the retaining pins, of the joint fastener comprising
opposite sections, one or both having inwardly extending. side. flanges and having
an intermediate longitudinal rib to enter the channel or channels of the band or
wire and having pins for uniting said section joints together, said pins passing
through the holes in the ends of the band, substantially as described.
2. The fastener for a retaining band or wire, said fastener consisting of
opposite sections, one or both of which sections having a rib to enter the channel
or channels of the band or wire and having transverse ribs adapted to be embedded
in the thickened portions of the band or wire.
