Improvements relating to the Manufacture of Wheel Rims.
I, CHARLES SANFORD DIKEMAN, of Torrington in the County of Litchfield
and State of Connecticut, United States of America, Manufacturer 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 :-
My invention relates to an improvement in clips for wheel rims. The object
is to so construct the clip that it will prevent the meeting ends of the rim from
springing apart, whereby the escape of the tyre is prevented.
With this end in view my invention consists in certain novel features of construc-
tion and combinations of parts which will be hereinafter described and pointed out
in the claims.
In the accompanying drawings, Fig. 1 is a view illustrating my invention in its
is a detached
operative position. Figure 2 is a cross section of Fig. 1. Figure
view; and Fig. 4 is a modification.
A represents the rim and b, b, the overlapping edges thereof, which latter are
adapted to hold the tire in position in the rim. The rim may be made in the usual
manner of any preferred material, as steel for instance, or of aluminium, which
I prefer.
The meeting ends of rim A are secured together by means of a clip B, which
latter forms the essential feature of my present improvement. The inwardly turned
flanges c, c, of clip B, are adapted to overlap the flanges b, b, of rim A, whereby
said flanges b, b, are held against outward movement. A hole e is centrally located
in clip B aud is adapted to align with hole f formed at or near the meeting ends of
said rim. Through holes e and f projects the usual valve, to which is attached when
necessary the device for inflating the tire.
The clip B can be made of any suitable material, but I prefer to construct the
same of aluminium, and also prefer to complete said clip before attaching it to
the rim.
The clip is applied as shown in Figure 1 and is secured to the rim by any suitable
means, rivets being preferably used. When the clip is in the position shown in
Figure 1, it will be apparent that the rim instead of being weak at its meeting point,
is really made stronger than at any other place in it. It will also be seen that the
meeting ends of the flanges b, b, will be prevented from turning outwardly, thus
making the escape of the tire at this point impossible.
In the modification, the rim has no side flanges and the clip therefore requires
none, it being made to conform to the shape of the rim and the two being securely held
together by rivets or other equivalent means. In this form the ends of the rim are
preferably cut off squarely and made to abut each other in the form of a heading
joint.
It is evident that other slight changes in the construction and relative arrangement
of the several parts might be made without avoiding my invention and hence I
would have it understood that I do not restrict myself to the particular construction
and arrangement of parts shown and described, but,
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :
1st. The combination with a wheel rim curved transversely the ends of which are
cut off squarely and made to abut against each other to form a heading joint, of a

page_text: having rivet holes formed therein to receive rivets whereby to secure the clip in
place on the rim ends whereby a secure and rigid joint is produced.
2nd. The combination with a wheel rim having overlapping tire clamping edges
formed by bending the edges of the material forming the rim inwardly towards
each other, of a clip consisting of a plate constructed to conform to and tightly fit
the exterior of the rim and the tire clamping edges whereby to effect a rigid joint
at the ends of the rim, substantially as set forth.
3rd. The combination with a wheel rim having overlapping tire clamping edges
formed by bending the edges of the material forming the rim inwardly towards each
-other, the ends of the rim made to abut each other and having a hole formed partly
in each of them for the valve, of a clip constructed to receive and hold the end of
the rim together, said clip having flanges which overlap and embrace the tire
-clamping edges of the rim, said clip having a hole therein adapted to align with the
hole in the rim, substantially as set forth.
