I WILLIAM PHILLIPS THOMPSON F.C.S., M.I.M.E. of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool and 6, Bank Street, Manchester both in
the County of Lancaster, and 323, High Holborn in the County of Middlesex, Civil
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to Metallic Wheel Rims, and pertains to improvements in
the construction of said rims and in means for connecting the outer ends of metallic
spokes with said rims, and the invention consists in the peculiar construction of a
wheel-rim, and in the construction and arrangement of the devices for attaching the
said rim to the spokes, all as hereinafter fully described.
In the drawing forming part of this specification, Figure 1 is a transverse sectional
view of a portion of a wheel rim constructed according to this invention said Figure
showing the outer end of a wheel-spoke connected to said rim by devices embodying
the improvements and showing the tire of the wheel in section. Figure 2, is a
sectional view of that part of the wheel-rim to which the spokes are attached, and a
side elevation of said spoke-attaching devices and of a part of a spoke. Figure 3, is
a sectional view of the spoke attaching nut. Figure 4, is a side elevation of one end
of a spoke and a longitudinal section of the bushing constituting one of said con-
necting devices.
In the drawing, 3, indicates the wheel rim which is of suitable metallic construction,
and is formed from a strip of sheet metal having the thickened portion, or rib, 4,
thereof, formed in said strips by rolling in the usual way.
When said strip of metal from which the rim is to be made is rolled or formed,
the said thickened portion, 4, thereof is brought nearer to one edge of said strip than
to the other, in order to leave sufficient width of sheet metal on one side of said strip

page_text: to form the side, a, of the rim, the tire-groove D, and to provide a border to one side
of said groove sufficiently wide to allow a hook c, to be formed thereon.
The sheet metal on the opposite side of said thickened portion, 4, is of sufficient
width to constitute the side e, of the rim, and the edge of said side, e, has an offset o,
formed thereon, the face of which is made to recede sufficiently towards the centre of
the tire-groove to receive the hook shaped edge, c, and to leave the outer surface of
said edge, c, in the same plane as tho side, e, of the rim, as shown in Figure 1.
The rim, 3, is formed by rolling in any well known manner familiar to persons
skilled in the art of so making hollow metallic wheel-rims. The above-described
manner of uniting the edge of the side, e, of the rim and the hook-shaped
edge, c, thereof forms a lap-joint at one edge of the rim about opposite the centre of
1.he tire.
Tho said thickened portion, 4, of the wheel-rim, 3, provides a sufficient thickness of
metal for rigidly securing the ends of the spokes, 5, of the wheel thereto, and said
thickened portion of the rim is drilled and tapped to adapt it to receive the nut, 6,
which is perforated longitudinally, as shown in Figure 3, has one end counter bored
as at,, in said Figure, to give to one end of said perforation an outwardly
tapering form, and is slotted, as shown, from said inwardly tapering end towards the
opposite end.
The end of the spoke, 5, which is attached to the wheel-rim is screw-threaded as
shown in Figure 4.
A bushing, 7, having an exterior diameter about equal to said perforation through
the nut, 6, is internally screw-threaded, and is adapted to be screwed onto the end
of the spoke, 5, as shewn. Said bushing is counter-bored at one end, as shown in said
Figure 4, and the last-named end of said bushing has a form given thereto, as
shown, which adapts it to have a wrench applied thereto to turn it, and on its outer
end is formed a head, f, which has its under side tapered to correspond with the
internally tapered end of the nut, 6.
The end of each spoke, 5, is connected to said thick portion of the rim, 3, as
follows. The nut, 6, is placed on the end of the spoke with its head towards the
wheel-hub, and the bushing, 7, is then screwed onto the end of the spoke, and
ordinarily it is not screwed fully onto the latter at first, in order that it may be finally
adjusted to place as below described. The nut, 6, is then brought up over the bushing,
as shown in Figures 1 and 2, and screwed into the thick portion of the rim, 3, and
finally by a wrench applied to the end of said bushing, the latter is screwed onto the
end of the spoke until its head, f, is brought into engagement with the internally
tapered end of said nut, or to the position shown in Figure 2, and the bushing is then
screwed onto the end of the spoke until the requisite tension is imparted to the latter,
it being understood, of course, that the opposite end of the spoke is rigidly attachod
to the hub of the wheel.
A Wheel-rim constructed as above described with the thickened portion, 4,
adapted to have the nut, 6, screwed therein for each spoke, together with said
nut and bushing as means of attaching the spokes to the rim, provides a spoke and
rim construction, in so far as it relates to connecting the ends of the spokes to
the rim, which possesses marked advantages over means heretofore employed for
making such connections.
One great advantage in said construction is that the end of the spoke is con-
nected to the rim entirely from the inner side of the latter, or that side opposite
to the tire-groove, and without making any perforation through the latter opposite
the ends of the spokes.
Another advantage pertaining to said construction is that by means of the bushing, 7,
and its screw-connection with the spoke, the desired tension of the latter may be
easily adjusted at all times.
The purpose of the longitudinal slot, z, in the internally tapered end of the nut, 6,
is to permit the slotted end of the nut to be spread more or less when the head of the
bushing is forced against it in tightening the spoke, and thereby to cause said nut to
be so locked in the rim that it cannot work loose.

page_text: The tire, 8, of the wheel may consist of the ordinary rubber one, or it may be made
of any other suitable material, and the sides, e and a, of the wheel rim may be made
either of the form shewn in Figure 1, or they may be curved from the thickened
portion, 4, to those parts of the rim constituting the borders of the tire-groove, D,
thereof.

COMPLETE SPECIFICATION.
Improvements in or relating to Metallic Wheels' Rims.
A communication from abroad by THE WARWICK CYCLE MANUFACTURING COMPANY,
a corporation of, and doing business at, Springfield, County of Hampden and
State of Massachusetts, United States of America.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E. of the Agency for Foreign
Patent Agents, 6, Lord Street, Liverpool, and 6 Bank Street, Manchester both in
the County of Lancaster, and 323, High Holborn in the County of Middlesex, Civil
Engineer, 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 Metallic Wheel Rims, and pertains to improvements in the
construction of said rims and in means for connecting the outer ends of metallic
spokes with said rims, and the invention consists in the peculiar construction
of a wheel-rim, and in the construction and arrangement of the devices for attaching
said rim to the spokes, all as hereinafter fully described, and pointed out in the
claims.
In the drawings filed with the provisional specification, Figure 1 is a transverse
sectional view of a portion of a wheel-rim constructed according to this invention,
said Figure showing the outer end of a wheel-spoke connected to said by rim devices
embodying the improvements, and showing the tire of the wheel in section. Figure 2
is a sectional view of that part of the wheel-rim to which the spokes are attached, and
a side elevation of said spoke-attaching devices and of a part of a spoke. Figure 3
is a sectional view of the spoke-attaching nut. Figure 4 is a side elevation of one
end of a spoke and a longitudinal section of the bushing constituting one of said
connecting devices.

page_text: In the drawing 3 indicates the wheel-rim which is of suitable metallic construction,
and is formed from a strip of sheet metal having the thickened portion, or rib 4
thereof, formed in said strip by rolling in the usual way. When said strip of metal
from which the rim is to be made, is rolled or formed, the said thickened portion 4
thereof is brought nearer to one edge of said strip than to the other in order to leave
sufficient width of sheet metal on one side of said strip to form the side a of the rim,
the tire-groove D, and to provide a border to one side of said groove sufficiently wide
to allow a hook c to be forined thereon.
с
The sheet metal on the opposite side of said thickened portion 4, is of sufficient
width to constitute the side e of the rim, and the edge of said side e has an offset o
formed thereon, the face of which is made to recede sufficiently towards the
centre of the tire-groove to receive the hook-shaped edge c and to leave the outer
surface of said edge c in the same plane as the side e of the rim, as shown in
Figure 1.
The rim 3 is formed by rolling in any well known manner familiar to persons
skilled in the art of so making hollow metallic wheel-rims. The above-described
manner of uniting the edge of the side e of the rim and the hook-shaped edge c
thereof forms a lap-joint at one edge of the rim about opposite the centre of the tire.
Tho said thickened portion 4 of the wheel-rim 3 provides a sufficient thickness of
metal for rigidly securing the ends of the spokes 5 of the wheel thereto, and said
thickened portion of the rim is drilled and tapped to adapt it to receive the nut 6
which is perforated longitudinally, as shown in Figure 3 has one end counter-bored
as at in said Figure, to give to one end of said perforation an outwardly
tapering form, and is slotted, as shown, from said inwardly tapering end towards the
opposite end.
The end of the spoke 5 which is attached to the wheel-rim is screw-threaded, as
shown in Figure 4.
A bushing 7 having an exterior diameter about equal to said perforation through
the nut 6 is internally screw-threaded and is adapted to be screwed onto the end of
the spoke 5 as shown. Said bushing is counter-bored at one end, as shown in said
Figure 4, and the last-named end of said bushing has a form given thereto, as shown,
which adapts it to have a wrench applied thereto to turn it, and on its outor end is
formed a head which has its under side tapered to correspond with the internally
tapered end of the nut 6.
The end of each spoko 5 is connected to said thick portion of the rim 3 as follows.
The nut 6 is placed on the ond of the spoke with its head towards the wheel-hub, and
the bushing 7 is then screwed onto the end of the spoke, and ordinarily is not
screwed fully onto the latter at first, in order that it may be finally adjusted to place
as below described. The nut 6 is then brought up over the bushing as shown in
Figures 1 and 2, and screwed into the thick portion of the rim 3 and finally, by a
wrench applied to the end of said bushing, the latter is screwed onto the end of the
spoke until its head fis brought into engagement with the internally tapered end of
said nut, or to the position shown in Figure 2, and the bushing is then screwed
onto the end of the spoke until the requisite tension is imparted to the latter, it
being understood, of course, that the opposite end of the spoke is rigidly attached to
the hub of the wheel.
A wheel-rim constructed as above described with the thickened portion 4 adapted
to have the nut 6 screwed therein for each spoke, together with said nut and
bushing as means of attaching the spokes to the rim, provides a spoke and rim
construction, in so far as it relates to connecting the ends of the spokes to the
rim, which possesses marked advantages over means heretofore employed for making
such connections.
One great advantage in said construction is that the end of the spoke is connected to
the rim entirely from the inner side of the latter, or that side opposite to the
tirc-groove, and without making any perforation through the latter opposite the ends
of the spokes.
Another advantage pertaining to said construction is that by means of the bushing 7

page_text: and its screw-connection with the spoke, the desired tension of the latter may be
easily adjusted at all times.
The purpose of the longitudinal slot z in the internally tapered end of the nut 6, is
to permit the slotted end of the nut to be spread more or less when the head of the
bushing is forced against it in tightening the spoke, and thereby to cause said nut to be
so locked in the rim that it cannot work loose.
The tire 8 of the wheel may consist of the ordinary rubber one, or it may be
made of any other suitable material, and the sides e and a of the wheel-rim may
be made either of the form shown in Figure 1, or they may be curved from the
thickened portion 4 to those parts of the rim constituting the borders of the tire-
groove, D thereof.
I would remark in conclusion that I am aware that tubular metallic wheel rims
thickened at their inner portions for attachment of the spokes are not new and I do
not claim such rims generally.
Having now particularly described and ascertained the nature of the said invention,
and in what manner the same is to be performed, as communicated to me by my
foreign correspondents, I declare that what I claim is :
1. A tubular metallic wheel-rin made from a strip of metal having the solid,
thickened rib 4 to which the ends of the spokes are connected, that portion of said
strip one side of said rib forming one side, the tire-groove of the rim, and having the
hook-shaped edge c the portion of said strip on the opposite side of said rib forming
the side e of the rim and having its edge offset to form, with said hook-shaped edge, a
lap-joint on one edge of the rim, substantially as set forth.
2. In combination with a hollow metallic wheel-rim having a rib 4 and with a
wheel-spoke 5 having a screw-threaded end, a hollow nut, 6, screwing, into said rib,
and a headed bushing 7 passing through said nut and engaging therewith and screwing
on to said spoke, substantially as set forth.
3. In combination with a hollow metallic wheel-rim having a rib 4 and with a
wheel-spoke 5 having a screw-threaded end, a hollow, longitudinally slotted nut 6
screwing into said rib, and a bushing 7 having a head whose under side is tapered
passing through said nut and engaging with the slotted end of said nut and screwing
on to said spoke, substantially as set forth.

.
In the drawing, 3, indicates the wheel rim which is of suitable metallic construction,
and is formed from a strip of sheet metal having the thickened portion, or rib, 4,
thereof, formed in said strips by rolling in the usual way.
When said strip of metal from which the rim is to be made is rolled or formed,

The end of the spoke, 5, which is attached to the wheel-rim is screw-threaded as
shown in Figure 4.
A bushing, 7, having an exterior diameter about equal to said perforation through
the nut, 6, is internally screw-threaded, and is adapted to be screwed onto the end
of the spoke, 5, as shown. Said bushing is counter-bored at one end, as shewn in said
Figure 4, and the last-named end of said bushing has a form given thereto, as
shown, which adapts it to have a wrench applied thereto to turn it, and on its outer

Improvements in or relating to Metallic Wheels' Rims.
A communication from abroad by THE WARWICK CYCLE MANUFACTURING COMPANY,
a corporation of, and doing business at, Springfield, County of Hampden and
State of Massachusetts, United States of America.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E. of the Agency for Foreign
Patent Agents, 6, Lord Street, Liverpool, and 6 Bank Street, Manchester both in
the County of Lancaster, and 323, High Holborn in the County of Middlesex, Civil
Engineer, 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 Metallic Wheel Rims, and pertains to improvements in the
construction of said rims and in means for connecting the outer ends of metallic
spokes with said rims, and the invention consists in the peculiar construction
of a wheel-rim, and in the construction and arrangement of the devices for attaching
said rim to the spokes, all as hereinafter fully described, and pointed out in the
claims.
In the drawings filed with the provisional specification, Figure 1 is a transverse
sectional view of a portion of a wheel-rim constructed according to this invention,
said Figure showing the outer end of a wheel-spoke connected to said by rin devices
embodying the improvements, and showing the tire of the wheel in section. Figure 2
is a sectional view of that part of the wheel-rim to which the spokes are attached, and
a side elevation of said spoke-attaching devices and of a part of a spoke. Figure 3
is a sectional view of the spoke-attaching nut. Figure 4 is a side elevation of one
end of a spoke and a longitudinal section of the bushing constituting one of said
connecting devices.

page_text: In the drawing 3 indicates the wheel-rim which is of suitable metallic construction.
and is formed from a strip of sheet metal having the thickened portion, or rib 4
thereof, formed in said strip by rolling in the usual way. When said strip of metal
from which the rim is to be made, is rolled or formed, the said thickened portion 4
thereof is brought nearer to one edge of said strip than to the other in order to leave
sufficient width of sheet metal on one side of said strip to form the side a of the rim,
the tire-groove D, and to provide a border to one side of said groove sufficiently wide
to allow a hook c to be formed thereon.
The sheet metal on the opposite side of said thickened portion 4, is of sufficient
width to constitute the side e of the rim, and the edge of said side e has an offset o
formed thereon, the face of which is made to recede sufficiently towards the
centre of the tire-groove to receive the hook-shaped edge c and to leave the outer
surface of said edge c in the same plane as the side e of the rim, as shown in
Figure 1.
The rim 3 is formed by rolling in any well known manner familiar to persons
skilled in the art of so making hollow metallic wheel-rims. The above-described
manner of uniting the edge of the side e of the rim and the hook-shaped edge c
thereof forms a lap-joint at one edge of the rim about opposite the centre of the tire.
The said thickened portion 4 of the wheel-rim 3 provides a sufficient thickness of
metal for rigidly securing the ends of the spokes 5 of the wheel thereto, and said
thickened portion of the rim is drilled and tapped to adapt it to receive the nut 6
which is perforated longitudinally, as shown in Figure 3 has one end counter-bored
as at in said Figure, to give to one end of said perforation an outwardly
tapering form, and is slotted, as shown, from said inwardly tapering end towards the
opposite end.
The end of the spoke 5 which is attached to the wheel-rim is screw-threaded, as
shown in Figure 4.
A bushing 7 having an exterior diameter about equal to said perforation through
the nut 6 is internally screw-threaded and is adapted to be screwed onto the end of
the spoke 5 as shown. Said bushing is counter-bored at one end, as shown in said
Figure 4, and the last-named end of said bushing has a form given thereto, as shown,
which adapts it to have a wrench applied thereto to turn it, and on its outer end is
formed a head which has its under side tapered to correspond with the internally
tapered end of the nut 6.
The end of each spoke 5 is connected to said thick portion of the rim 3 as follows.
The nut 6 is placed on the end of the spoke with its head towards the wheel-bub, and
the bushing 7 is then screwed onto the end of the spoke, and ordinarily it is not
screwed fully onto the latter at first, in order that it may be finally adjusted to place
as below described. The nut 6 is then brought up over the bushing as shown in
Figures 1 and 2, and screwed into the thick portion of the rim 3 and finally, by a
wrench applied to the end of said bushing, the latter is screwed onto the end of the
spoke until its head is brought into engagement with the internally tapered end of
said nut, or to the position shown in Figure 2, and the bushing is then screwed
onto the end of the spoke until the requisite tension is imparted to the latter, it
being understood, of course, that the opposite end of the spoke is rigidly attached to
the hub of the wheel.
A wheel-rim constructed as above described with the thickened portion 4 adapted
to have the nut 6 screwed therein for each spoke, together with said nut and
bushing as means of attaching the spokes to the rim, provides a spoke and rim
construction, in so far as it relates to connecting the ends of the spokes to the
rim, which possesses marked advantages over means heretofore employed for making
such connections.
One great advantage in said construction is that the end of the spoke is connected to
the rim entirely from the inner side of the latter, or that side opposite to the
tire-groove, and without making any perforation through the latter opposite the ends
of the spokes.
Another advantage pertaining to said construction is that by means of the bushing 7

page_text: and its screw-connection with the spoke, the desired tension of the latter may be
easily adjusted at all times.
The purpose of the longitudinal slot z in the internally tapered end of the nut 6, is
to permit the slotted end of the nut to be spread more or less when the head of the
bushing is forced against it in tightening the spoke, and thereby to cause said nut to be
so locked in the rim that it cannot work loose.
The tire 8 of the wheel may consist of the ordinary rubber one, or it may be
made of any other suitable material, and the sides e and a of the wheel-rim may
be made either of the form shown in Figure 1, or they may be curved from the
thickened portion 4 to those parts of the rim constituting the borders of the tire-
groove, D thereof.
Having now particularly described and ascertained the nature of the said invention,
and in what manner the same is to be performed, as communicated to me by my
foreign correspondents, I declare that what I claim is :
1. A tubular metallic wheel-rim made from a strip of metal having the solid,
thickened rib to which the ends of the spokes are connected, that portion of said
strip one side of said rib forming one side, the tire-groove of the rim, and having the
hook-shaped edge c the portion of said strip on the opposite side of said rib forming
the side e of the rim and having its edge offset to form, with said hook-shaped edge, a
lap-joint on one edge of the rim, substantially as set forth.
2. In combination with a hollow metallic wheel-rim having a rib 4 and with a
wheel-spoke 5 having a screw-threaded end, a hollow nut, 6, screwing, into said rib,
and a headed bushing 7 passing through said nut and engaging therewith and screwing
on to said spoke, substantially as set forth.
3. In combination with a hollow metallic wheel-rim having a rib 4 and with a
wheel-spoke 5 having a screw-threaded end, a hollow, longitudinally slotted nut 6
screwing into said rib, and a bushing 7 having a head whose under side is tapered
passing through said nut and engaging with the slotted end of said nut and screwing
on to said spoke, substantially as set forth.
