Certain Improvements in the Manufacture of Metallic Wheel Rims
for Bicycles and other Velocipedes, Motor Cars and Road Vehicles.
I, SYDNEY PHILLIPS, of 215, New John Street West, in the City of Birmingham,
Manufacturers Manager, do hereby declare the nature of this invention to be as
follows:-
-
This invention consists of the herein described improvements in the manu-
facture of metallic wheel rims for bicycles and other velocipedes motor cars and
road vehicles. At the present time what is known as a "junctionless" or "joint-
less" wheel rim is made from a sheet metal disc which by stamping or spinning
is raised into a shallow dish shape the bottom of which is cut out leaving the
rim like a short cylinder which by means of rolling or spinning processes carried
on by suitable tools worked in a lathe is formed into the required trough section
rim thus making what is called a junctionless or jointless rim, as it has no cross
joint or seam. The disc like bottom which is cut out of the dish is waste metal
unless it can be put to some useful purpose. The discs of which the said junction-
less or jointless rims are at present formed are so thick that sometimes it is diffi-
cult to find a ready sale for the said disc like bottoms and therefore the manu-
facture of the rims is not carried on so profitably as it would be if the disc like
bottoms were much thinner as they could then he sold at a good price.
The object of my invention is to so make the said wheel rims from thin tinned
sheet iron or steel that although the finished rims will be as thick and strong as
heretofore the disc like bottoms will be much thinner so as to command a ready
sale for use in the manufacture of various articles of tin ware.
Moreover by my
invention I diminish the risk of the rim breaking at an unknown fracture and
I make the rims stronger than heretofore without adding to their weight.
In carrying out my invention instead of as heretofore operating on a sheet metal
blank which is of the same gauge as the finished rim I operate on two three or
more very thin tinned sheet steel or sheet iron blanks laid together the combined
thicknesses of which will be equal to the thickness of the finished rim. These said
tinned blanks' are laid together one on the top of the other and by means of suit-
able dies or tools in a press I raise these blanks together into one shallow dish
like shape with the edge or flange turned outwardly and I pierce out the bottom
leaving the rim like a hoop or short cylinder of two three or more thicknesses
of metal according to the number of blanks of which the dish is formed. Or the
blanks may be raised separately and their bottoms pierced out thus leaving
separate hoops which are inserted and fitted one within the other to form the said
rim of two three or more thicknesses. By means of suitable tools or dies in a
spinning lathe or by other means the said cylinder or rim is rolled or otherwise
formed into the required trough section wheel rim which will thus be of two three
or more thicknesses of metal fitting close together. The two three or more thick-
nesses of metal forming the said wheel rim are then soldered or sweated together
by being heated uniformally so as to melt the tin on their adjacent surfaces

of gas burners which play upon the said rim while it is revolving or the said wheel
rim may be dipped into a bath of molten tin and kept there until the tin on the
adjacent surfaces is melted. When cold the two three or more thicknesses of
metal composing the rim will adhere together forming a rim of the required
strength and thickness. Thus in making each rim I produce two or three thin
discs which being of thin gauge can as aforesaid be sold at a good price as they
are in constant demand for making various articles of tin ware.
When building up the wheel rim from the two three or more hoops formed and

the part of the rim through which the spokes pass.

improved wheel rim is formed should be fractured the rim may still be sound as

rim. Moreover by making the wheel rims as above described I

Certain Improvements in the Manufacture of Metallic Wheel Rims
for Bicycles and other Velocipedes, Motor Cars and Road Vehicles.
I, SYDNEY PHILLIPS, of 215, New John Street West, in the City of Birmingham,
Manufacturers Manager, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
"
This invention consists of the herein described improvements in the manu-
facture of metallic wheel rims for bicycles and other velocipedes motor cars and
road vehicles. At the present time what is known as a junctionless" or joint-
less" wheel rim is made from a sheet metal disc which by stamping or spinning
is raised into a shallow dish shape the bottom of which is cut out leaving the rim
like a short cylinder which by means of rolling or spinning processes carried on by
suitable tools worked in a lathe is formed into the required trough section thus
making what is called a junctionless or jointless rim as it has no cross joint or
seam. The disc like bottom which is cut out of the dish is waste metal unless
it can be put to some useful purpose. The discs of which the said junctionless or
jointless rims are at present formed are so thick that sometimes it is difficuit to
find a ready sale for the said disc like bottoms and therefore the manufacture
of the rims is not carried on so profitably as it would be if the disc like bottoms
were much thinner as they could then be sold at good prices.
The object of my invention is to so make the said wheel rims from thin tinned
sheet iron or steel that although the finished rims will be as thick and strong as
heretofore the disc like bottoms will be much thinner so as to command a ready
sale for use in the manufacture of various articles of tin ware. Moreover by my
invention I diminish the risk of the rim breaking at an unknown fracture and I
make the rims stronger than heretofore without adding to their weight.
.
I will describe my invention by referring to the accompanying drawings, c
on

page_text: which Fig. 1 is a cross section of a wheel rim constructed in accordance, with this
invention suitable for use with a pneumatic tyre of the Welch-Dunlop type;
Figs. 2 and 3 illustrate two stages in the manufacture of the same; Fig. 4 is a cross
section of anotlier form of wheel rim constructed in accordance with my invention
suitable for use with a pneumatic tyre of the Clincher type; and Fig. 5 is a cross
section of another form of wheel rim suitable for use with a pneumatic tyre of
the Welch-Dunlop type."
The same letters of reference indicate the same or corresponding parts in all
the figures of the urawings.
In carrying out my invention instead of as heretofore operating on a sheet metal
blank which is of the same gauge as the finished wheel rim I operate on two
three or more (say for instance three) very thin tinned sheet steel or sheet iron
blanks which I will call respectively A B and C laid together the combined thick-
nesses of which will be equal to the thickness of the finished rim. These tinned
blanks A, B and C are laid together one on the top of the other and by means of
suitable dies or tools in a press raise these blanks together into one shallow
dish like shape such as shewn in Fig. 2 with the edge or flange part marked e
turned outwardly and I pierce out the bottoni f leaving the rim like a hoop or
short cylinder as shewn in Fig. 3 of three thicknesses of metal, or of two or more
than three thicknesses according to the number of blanks of which the dish is
formed. Or the blanks A B C may be raised separately to the form shewn in
Fig. 2 and their bottoms pierced out separately thus leaving three separate hoops
which are inserted and fitted one within the other to form the rim of three thick-
nesses as shewn in Fig. 3 or of two or more than three thicknesses. By means
of suitable well known tools or dies in a spinning lathe or by other weil known
means the cylinder or rim shewn in Fig. 3 is now rolled or otherwise formed into
the required trough section wheel rim shewn in Fig. 1 which will thus be of three
thicknesses of metal marked respectively A B C fitting close together. The thick-
nesses of metal forming the wheel rim shewn in Fig. 1 are then soldered or
sweated together by being heated uniformly so as to melt the tin on their adjacent
surfaces which may conveniently be done by dipping the rim into a bath of molten
tin and keeping it there until the tin of the adjacent surfaces is melted. Or
other means for heating the rim to melt the tin may be employed such as
an appliance composed of gas burners arranged to play upon the wheel rim while it
is revolving but such appliance needs no further description here as it forms
no part of my present invention. When cold the two three or more thicknesses
of metal A B and C composing the rim shewn in Fig. 1 will adhere together form-
ing the rim of the required strength and thickness. Thus in making each rim
I produce two three or more thin discs corresponding with the bottom f of the
dish shewn in Fig. 3 which discs being of thin gauge can as aforesaid he sold at a
good price as they are in constant demand for making various articles of in ware.
When building up the wheel rim from the two three or more hoops formed and
fitting one within another as above described some one or more of the said hoops
may be of less width than the others and be fixed so as to strengthen the part of
the rim through which the spokes pass. For instance as shewn in Figs. 4 and 5
the hoop A is made of less width than the other two hoops B C so as to strengthen.
the central portion of the rim.
If any one of the two three or more hoops or thicknesses of metal of which my
improved wheel rim is formed should be fractured the rim may still be sound as such
fracture may not extend through the other thickness or thicknesses of the rim.
Moreover by making the wheel rims as above described I can add to their strength
without increasing their weight as I can arrange for the blanks to be disposed
with their grain at right angles or at other angles to one another thus reducing
the liability of fracture.
It will be understood that my invention is not limited to the precise sections
of wheel rims shewn upon my drawings as these are only intended as examples,

page_text: my invention being applicable to trough section wheel rims of many different
sections as will readily be understood.
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. The improved method of manufacturing a trough section metallic wheel
rim for bicycles and other velocipedes motor cars and road vehicles, consisting
in stamping two or more thin tinned sheet iron or tinned sheet steel blanks
together one above the other or others into a shallow dish shape, piercing out the
bottom of the same and thereby forming thin discs corresponding in number with
the blanks which are being used to form the rim and leaving a hoop or rim of two
or more thicknesses throughout which by rolling in a lathe or by other means is
formed into the required trough section and is heated so as to cause the adjacent
surfaces to adhere together and thus form a wheel rim, substantially as described.
2. The improved method of manufacturing a trough section wheel rim for
bicycles and other velocipedes motor cars and road vehicles consisting in stamping
two or more thin tinned sheet iron or tinned sheet steel blanks separately
into a shallow dish shape to fit one within the other or others pierc-
ing out the bottoms of the same leaving hoops or rims which
fitted one within the other or others and are afterwards rolled or
otherwise formed into the required trough section and are heated
as to cause their adjacent surfaces to adhere together and thus form a wheel rim
of two or more thicknesses substantially as described.

stantially as herein before described.
4. A trough section wheel rim for bicycles and other velocipedes motor cars
and road vehicles formed throughout. of two or more thicknesses of thin tinned
sheet iron or tinned sheet steel hoops which have been stamped and worked
