Wheels of Velocipedes, Road Carriages, and the like.
I, HENRY PIEPER, of 16, Rue des Bayards, Liége, in the Kingdom of Belgium,
Manufacturer of Fire-arms, do hereby declare the nature of this invention to be
as follows:-
This invention relates to the construction of improved metallic tyres for veloci-
pede and road-vehicle wheels, and has for its principal object to avoid the jointing
of metallic tyres or fellies used for cycles, carriages, motor cars and the like.
It consists in constructing the tyre or felly of a plurality of laminated rings
or circular strips or hoops which are without brazed, soldered or welded ends, and
which rings may be stamped or rolled out, being afterwards riveted or clinched
together, in such a manner that the ends or joints are not all in the same place
but are covered over being divided around the circumference of the tyre.
By this method of construction I avoid the usual brazing or welding of the
joints and the subsequent structural change of the metal at that part, which may
thereby be entailed. The tyre especially retains around the whole of its contour
or circumference, the qualities of springiness and rigidity inherent in the metal
employed.
The section of the fellies or tyres so obtained may be varied, as desired; the
examples shewn in the annexed drawings will be sufficient to represent in general
the construction of my improved tyre, at various stages in its manufacture.
Referring to these drawings,
Upon a ring or suitable strip of metal curved to the shape of a circular hoop,
the ends being left free and unjointed, and of a section such as is shewn at A on
Figure 1 and provided with two indented ribs B and C, I place internally a second
ring or strip of metal D such as shewn at Figure 2, in such a manner that the
junctions or ends of each ring are at different points or places; for example
(see Figure 16) at E and G for the outer and inner hoops respectively. The ribs B
and C of the outer ring are afterwards bent back by any suitable means, over
and upon the inner ring D, as is shewn on Figure 3.
I then form the two beads or treads H and J for the tyre, Figure 4, which are
made by bending back (by rolling or otherwise) the two edges of the ring A on
to a hoop or core K formed of metal and of a section suitable for the final shape
of the treads. The two beads or treads H and J may also be formed as shewn on
Figure 5.
The second example is represented by
Figures 11, 12, 13, and 14, which latter shew different stages in the manufac-
ture of a tyre of another section and of a construction identical with that above

The section of the fellies or tyres so obtained may be varied as desired; the
examples shewn in the drawings filed with my Provisional Specification will be
sufficient to represent in general the construction of my improved tyre at various
stages in its manufacture.
Referring to those drawings,
Upon a ring or suitable strip of metal curved to the shape of a circular hoop,
the ends being left free and unjointed, and of a section such as is shewn at A on
Figure 1 and provided with two indented ribs B and C, I place internally a second
ring or strip of metal 1) such as shewn at Figure 2, in such a manner that the
junctions or ends of each ring are at different points or places; for example
(see Figure 16), at E and G for the outer and inner hoops respectively. The ribs B
and C of the outer ring are afterwards bent back by any suitable means, over
and upon the inner ring D, as is shewn on Figure 3.
I then form the two beads or treads H and J for the tyre, Figure 4, which are
made by bending back (by rolling or otherwise) the two edges of the ring A on
to a hoop or core K formed of metal and of a section suitable for the final shape
of the treads. The two beads or treads H and J may also be formed as shewn on
Figure 5.
The second example is represented by,
Figures 11, 12, 13, and 14, which latter shew different stages in the manufac-
ture of a tyre of another section and of a construction identical with that above
described. In this modification the edges of the ring A may each be furnished
or strengthened with a liner or ring L the inner edge of which has previously been
inserted into the hollow of the ribs B and C and is bent back with each of these
ribs as is shewn on Figure 5. The beads or treads H and J are then formed by
bending or rolling the rings A and L together. In this case the ends of the
different rings or circular strips might be situated as shewn for example, on
Figure 16, namely at E and G for the rings A and D and at M and O for the
rings L.
3rd and 4th examples.
Figures 6, 7, 8, and 9 shew two other sections of tyres or fellies constructed in
the same manner but with the differences that the ribs B and C are dispensed with,
and that the ring D is widened or extended laterally to the dimension or width
of the ring A with which it is bent back to form the two beads H and J. Although
the mechanical shaping or stamping of the rings A and D suffices to prevent their
sliding one on the other, corrugations or undulations may be impressed or formed
on the strip or sheet of these as and where desired; for instance I may suitably
corrugate them by means of grooved rollers R and S as shewn on Figure 10.
Further, the insertion of the nipple heads of the spokes will prevent any
slipping or independent motion of the two rings.
The various rings or hoops may also be riveted one to another as shewn on
Figure 15.
The rings or hoops being (preferably) made of steel polished and previously
punched, stamped or rolled to sections, I may solder or connect one to the other,
the different parts of the tyre, by immersing them in a suitable tin bath or bath
of melted tin.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is
The construction of metallic tyres (fellies). for the wheels of velocipedes, road
carriages and the like, formed of various rings or circles with unsoldered joints
or free ends which rings are riveted or fastened together in such a manner that the
