Improvements in Rims for Wheels of Cycles and other Vehioles.
We WILLIAM JOSEPH GODDARD Secretary and Manager to a Public Company
and ALFRED HENRY TRIGWELL Mechanical Engineer both of 136 Great Saifron
Hill in the County of London do hereby declare the nature of this invention to
be as follows:-
Our invention relates to rims for the wheels of cycles and other vehicles and
refers particularly to the method of fastening the circumferential joint of such
rims in those cases where the rim is a hollow rim made out of a single piece of
strip steel or other metal which is fashioned into the desired shape by rolling or
drawing or both and is afterwards bent into a circular shape and the ends made to
butt and join so as to form the rim of a wheel for holding a pneumatic tyre or a
rubber tyre of any kind. It has hitherto been customary for the circumferential
joint in such rims to be fastened by soldering or brazing. In carrying out our
invention we fasten the circumferential joint in the following manner. Having
rolled or drawn the strip steel or other metal into the shape suitable for forming
the rim intended to be made and the drawn strips being then in such a form
that the two sides of the strip are meeting and one of the edges overlapping the
other in the centre of the rim and such edges being rolled close down to the
bottom of the rim are forming a threefold thickness of metal at the point intended
eventually to receive the spokes of the wheel or the two sides may be turned under
and meeting and one of the edges underlapping the other in the centre of the rim
or they may be folded and keyed into one another forming a five-fold thickness of
metal at the point eventually intended to receive the spokes of the wheel. We take
these strips and without any further fastening we bend them at once into a circular
shape until the ends butt. We fasten the ends by brazing soldering or rivetting as
may be most convenient and with or without a bridge piece as occasion requires.
Having brought our rim into the necessary circular shape we proceed to carry out the
process which constitutes the essence of our invention. We drill or punch or by
other convenient means form at the proper place in the rim the holes to receive
the spokes of the wheel. Into each of these holes we insert a small. sleeve or
collar or eyelet formed of steel, brass copper, aluminium or other suitable metal
and we fasten each eyelet by punching it down close to the rim with an ordinary
We thus form
eyeletting punch or other convenient eyeletting tool or apparatus.
an efficient fastening for the circumferential joint of the rim. Finally we solder
the edge of the circumferential joint completing the fastening of the rim. The
eyelets or sleeves will in the ordinary hollow rim with a single thickness of metal
at the bottom take the place of the hard steel washers generally used to prevent
the spokes pulling through.

Improvements in Rims for Wheels of Cycles and other Vehicles.
We, WILLIAM JOSEPH GODDARD, Secretary, and Manager to a Public
Company and ALFRED HENRY TRIGWELL, Mechanical Engineer both of
136 Great Saffron Hill in the County of London 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 rims for the wheels of cycles and other vehicles
and will be best understood by reference to the accompanying drawings in
which ;-
Fig. 1 is a perspective view of a tubular rivet or eyelet which we employ for
fastening the joints according to our invention.
Figs. 2 to 8 are sections of various forms of rim constructed according to this
invention and
Fig. 9 is a perspective view of a portion of rim constructed in the manner
illustrated in Fig. 2.
Like letters indicate like parts throughout the drawings.
Iu constructing wheel rims as shown in Figs. 2 to 5 out of one strip of sheet
metal, say first a rim having a form in section such as shown in Fig. 2, we bend
the strip to this form, either by drawing it through dies or rolling it or by both of
these processes. The strip is then bent in the direction of its length to a circular
form and the ends secured together in any of the usual ways. We next drill holes
through the rim at the parts to which the spokes are to be secured (at which part
there are three thicknesses of the sheet metal) and secure the three thicknesses of
the metal together by means of tubular rivets A, the rivetting being effected at
either the outside or inside of the rim and by a eyeletting machine or other means.
The internal diameter of the tubular rivets is slightly greater than that of the
spoke-nipple B Fig. 6 just below the head B', and these rivets are adapted to
receive and allow of the rotation therein of the spoke-nipples, the heads B¹
preventing the nipples from being pulled through the rim.
The rim shown in Fig. 3 instead of having the over-lapping edges of the strip
at the outside of the rim as in Fig. 2, has them in the inside; in other respects
this rim is substantially similar to that shown in Fig. 2.
The rim shown in Fig. 4 differs from that shown in Fig. 2 in that its edges
instead of being merely laid one on the other, are folded together whereby the
joint is rendered more secure. In this arrangement instead of the hollow rivets
passing through three thicknesses of the sheet metal as in Fig. 2, they pass
through five thicknesses, and the rigidity of the whole rim is considerably augmented.
The sectional shape of this rim is slightly modified as compared with Figs. 2
and 3 but if desired the improvements embodied in Fig. 4 may be applied to rims
of various forms, for example, instead of the two edges of the sheet metal being
folded together at the outside of the rim, they may be folded together at the inside
of the rim, the tubular rivets passing through the whole five thicknesses of the
sheet metal as in Fig. 4.
In Fig. 5 the two edges of the sheet metal are folded together at the inside of
the rim and the hollow rivets A pass through and secure together only four of the
five thicknesses of the sheet metal, riz.;-the folded edges, the fifth thickness
being at a little distance away and provided with apertures Copposite the rivets A
and large enough to admit of the spoke-nipple-heads B' and the spoke-nipple key
being passed through it. If desired instead of the two edges being folded together
as shown in Fig. 5 they may merely overlap each other, the rim in all other respects
being as in Fig. 5.
In all the foregoing examples the hollow rivets may be applied after the rim is
in its circular form, but when it is required to apply them to a rim having a cross

page_text: section such as shown in Fig. 6, they are applied before the rim is brought to this
form and while it is straight so as to admit of a mandrel being inserted into it to
support the heads of the rivets during the rivetting operation, after which the
mandrel is withdrawn. In this construction of rim the tubular rivets A like the
holes C shown in Fig. 5 must have their internal diameter large enough to admit
of the spoke-socket-heads B¹ and the key for manipulating the spoke-sockets
passing freely through them. In this construction where the joint is at the outside
of the rim, the spoke-sockets B pass through only one thickness of the sheet metal
and the tubular rivets A through two (the overlapping edges) but when the joint
is at the inside of the rim the spoke-sockets are fitted in the tubular rivets which
connect the overlapping edges and holes are formed in the outer part of the rim
to enable the spoke-sockets to be placed in position and otherwise manipulated.
In a rim formed of two separate strips of sheet metal as shown in Figs. 7 and 8
having one (D) a concave form and the other (E) a channelled form in cross
section, the strip E may be bent over the edges of the strip D as shown in Fig. 7
or the edges of both of the strips may be folded together as shown in Fig. 8.
These united edges are then drilled and the tubular rivets A rivetted through
them; in the former example the rivets A pass through three thicknesses of the
sheet metal and in the latter, five thicknesses.
The strips E, Figs. 7 and 8 are provided with apertures C for the same purpose
as those described in connection with Fig. 5.
In addition to using the tubular rivets A we may solder, braze or otherwise
treat the joints so as to ensure the exclusion of air from the interior of the rim and
thereby minimize the possibility of rust or corrosion.
By the term intermediate part' hereinafter used in the claims we mean a part
located between the edges which are secured together by the tubular rivets in the
manner before described, and these edges would appear in a cross section of the
rim. We are aware that nipple-ferrules have been used for the purpose of
transferring the strain of the spoke-nipple from the inner to the outer section of
double section rims and we wish it understood that we do not claim any such
arrangement.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is ;-
1. The combination with a wheel rim of a tubular rivet.
2. The combination with a wheel-rim formed of bent or folded sheet-inetal of
one or more tubular rivets passing through its overlapping or folded edges.
3. A wheel rim formed of bent or folded sheet-metal having its edges secured
together by one or more tubular rivets which also pass through the sheet-metal at
an intermediate part.
4. A wheel rim formed of bent or folded sheet metal having its edges secured
together by one or more tubular rivets and having at an intermediate part
perforations through which access may be had to the rivets substantially as and
for the purpose described.
5. The combination with a wheel rim of a tubular rivet through which the
spoke or spoke-nipple passes.
6. A wheel rim constructed and having a cross section substantially as described
in Figs. 2, 3, 4, 5, 6, 7 or 8 of the accompanying drawings.
Dated this 27th day of November 1895.
